Mozilla Launches a New Startup Focused on 'Trustworthy' AI
by Peter Reutemann 23 Mar '23

23 Mar '23

'On the eve of its 25th anniversary, Mozilla, the not-for-profit behind the Firefox browser, is launching an AI-focused startup. From a report: Called Mozilla.ai, the newly forged company's mission isn't to build just any AI -- its mission is to build AI that's open source and "trustworthy," according to Mark Surman, the executive president of Mozilla and the head of Mozilla.ai. "Working on trustworthy AI for almost five years, I've constantly felt a mix of excitement and anxiety," he told TechCrunch in an email interview. "The last month or two of rapid-fire big tech AI announcements has been no different. Really exciting new tech is emerging -- new tools that have immediately sparked artists, founders ... all kinds of people to do new things. The anxiety comes when you realize almost no one is looking at the guardrails." Surman was referring to the rash of AI models in recent months that, while impressive in their capabilities, have worrisome real-world implications. At release, OpenAI's text-generating ChatGPT could be prompted to write malware, identify exploits in open source code and create phishing websites that looked similar to well-trafficked sites. Text-to-image AI like Stable Diffusion, meanwhile, has been co-opted to create pornographic, nonconsensual deepfakes and ultra-graphic depictions of violence. The creators of these models say that they're taking steps to curb abuse. But Mozilla felt that not enough was being done. "We've been working on trustworthy AI on the public interest research side for about five years, hoping other industry players with more AI expertise would step up to build more trustworthy tech," Surman said. "They haven't. So we decided mid-last year we needed to do it ourselves -- and to find like-minded partners to do it alongside us. We then set out to find someone with the right mix of academic and industry AI experience to lead it." Funded by a $30 million seed investment from the Mozilla Foundation, Mozilla's parent organization, Mozilla.ai is a wholly owned subsidiary of the Mozilla Foundation -- much like the Mozilla Corporation (the org responsible for developing Firefox) and Mozilla Ventures (the Mozilla Foundation's VC fund). Its managing director is Moez Draief, who previously was the chief scientist at Huawei's Noah's Ark AI lab and the global chief scientist at consulting company Capgemini.' -- source: https://tech.slashdot.org/story/23/03/22/1510255 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Russian Developers Blocked From Contributing To FOSS Tools
by Peter Reutemann 22 Mar '23

22 Mar '23

'The Reg has seen two recent incidents of Russian developers being blocked from public development of FOSS code. One was a refusal on the Linux kernel mailing list, the other a more general block on Github. In the last week, these events have both caused active, and sometimes heated, discussions in FOSS developer communities. From the report: The GitHub account of developer Alexander Amelkin has been blocked, and his repositories marked as "archived" â" including ipmitool, whose README describes it as "a utility for managing and configuring devices that support the Intelligent Platform Management Interface." Unable to comment on Github itself, Amelkin described what happened on the project's older Soureforge page. Amelkin works for Russian chipbuilder Yadro, which we described as working on RISC-V chips back in 2021. Microsoft is just obeying US law in this: according to the War and Sanctions database of the Ukrainian National Agency on Corruption Prevention, the NACP, Yadro is a sanctioned company. However, on LinkedIn, Amelkin disputes his employer's involvement. Over on Hacker News, commentators seem to be generally in favor of the move, although the discussion on LWN is more measured, pointing out both that there is little threat from server-management tools like this, but that Microsoft probably has no choice. Amelkin is not alone. Over on the Linux Kernel Mailing List, a contribution from Sergey Semin has been refused with the terse notice: "We don't feel comfortable accepting patches from or relating to hardware produced by your organization. Please withhold networking contributions until further notice." Semin is a developer at chipmaker Baikal Electronics, a company whose website has been suspended for a year now, as we noted a year ago in a story that also mentions Yadro. We were reporting on Baikal's efforts to develop its own CPUs nearly a decade ago, mere months after the Russian annexation of Crimea. And once again, there is spirited debate over the move on the Orange Site.

ASUS Unveils the Tinker V As Their First RISC-V Board
by Peter Reutemann 21 Mar '23

21 Mar '23

'Phoronix: For over a half-decade ASUS has been selling the Tinker Board devices as their line of Raspberry Pi alternatives. To date the ASUS Tinker Board single board computers have all been Arm-based while now they have launched their first RISC-V board, the Tinker V. The ASUS Tinker V is their first RISC-V single board computer and intended for the industrial IoT (Internet of Things) developer community. The ASUS Tinker V is set to officially run Debian Linux and Yocto while surely with time more Linux distributions will be supported.... Being IoT focused, there isn't any display support. Those interested in learning more about the ASUS Tinker V can do so via tinker-board.asus.com. The Register notes that Asus "is offering at least five years of support for Tinker V... Dedicated on-site technical support is also available to shorten customer development cycles and accelerate application deployment." The move shows that the RISC-V open-source instruction set architecture continues to garner support. The last RISC-V Summit in San Jose saw the launch of a family of datacenter-class processors based on the architecture from Ventana Micro Systems, while XMOS unveiled new high-performance microcontrollers using RISC-V. According to Asus, Tinker V samples will be available in Q2 of this year, but it did not disclose a date for full availability or pricing.' -- source: https://hardware.slashdot.org/story/23/03/20/0034207 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Question please re: How to attach an Android (Samsung cellphone Galaxy A03S) photo to a Gmail email using Firefox and Ubuntu
by Michael James 20 Mar '23

20 Mar '23

G'day... Can anyone please suggest how to attach a photo - (from a Samsung Galaxy A03S cellphone via USB cable from the phone to a desktop) - onto a Gmail email using Firefox and running Ubuntu. Have tried connecting the phone via USB to the desktop and clicking the attach button on the email and double clicking the file in the Ubuntu Files folder under the Activities heading. This does not work. I tried both right and left mouse options and the 'OPEN' option; I also tried copying the file (photo) to downloads and attempted to attach via the same above pathway but this did not work either. I came across this post (below) on the internet from 2010 with the same question and the following answer: https://superuser.com/questions/132783/how-to-email-photo-from-ubuntu-f-spo… I'm not familiar with Python code and wonder if this answer is now outdated? Wondering if the problem is with Firefox? Gmail is running fine on Ubuntu with Firefox, it's just the attaching of photos from the Android that's giving trouble. Short of using the phone itself or Thunderbird or any other email service to send the photo, is there a way to attach photos to Gmail emails via Firefox running on Ubuntu please? Thanks, Michael James __________________________________________________________________________________________

Google tells users of some Android phones: Nuke voice calling to avoid infection
by Peter Reutemann 20 Mar '23

20 Mar '23

'Google is urging owners of certain Android phones to take urgent action to protect themselves from critical vulnerabilities that give skilled hackers the ability to surreptitiously compromise their devices by making a specially crafted call to their number. It’s not clear if all actions urged are even possible, however, and even if they are, the measures will neuter devices of most voice-calling capabilities. The vulnerability affects Android devices that use the Exynos Modem 5123, Exynos Modem 5300, Exynos 980, Exynos 1080, Exynos Auto T5123 chipsets made by Samsung’s semiconductor division. Vulnerable devices include the Pixel 6 and 7, international versions of the Samsung Galaxy S22, various mid-range Samsung phones, the Galaxy Watch 4 and 5, and cars with the Exynos Auto T5123 chip. These devices are ONLY vulnerable if they run the Exynos chipset, which includes the baseband that processes signals for voice calls. The US version of the Galaxy S22 runs a Qualcomm Snapdragon chip. A bug tracked as CVE-2023-24033 and three others that have yet to receive a CVE designation make it possible for hackers to execute malicious code, Google’s Project Zero vulnerability team reported on Thursday. Code-execution bugs in the baseband can be especially critical because the chips are endowed with root-level system privileges to ensure voice calls work reliably.' -- source: https://arstechnica.com/information-technology/2023/03/critical-vulnerabili… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux 6.4 AMD Graphics Driver Picking Up New Power Features For The Steam Deck
by Peter Reutemann 20 Mar '23

20 Mar '23

'Phoronix: A pull request of early AMDGPU kernel graphics driver changes was submitted for DRM-Next on Friday as some of the early feature work accumulating for the Linux 6.4 kernel cycle. Among the AMDGPU kernel driver changes this round are a number of fixes affecting items such as the UMC RAS, DCN 3.2, FreeSync, SR-IOV, various IP blocks, USB4, and more. On the feature side, mentioned subtly in the change-log are a few power-related additions... These additions are largely focused on Van Gogh APUs, which is notably for the Valve Steam Deck and benefiting its graphics moving forward. First up, this kernel pull request introduces a new sysfs interface for adjusting/setting thermal throttling. This is wired up for Van Gogh and allows reading/updating the thermal limit temperature in millidegrees Celsius. This "APU thermal cap" interface is just wired up for Van Gogh and seems to be Steam Deck driven feature work so that SteamOS will be better able to manage the thermal handling of the APU graphics.... These power features will be exposed via sysfs while Steam OS will wrap around them intelligently and possibly some new UI settings knobs for those wanting more control over their Steam Deck's thermal/performance.

Most Failed Drives Fail Before 3 Years Of Use
by Lawrence D'Oliveiro 19 Mar '23

19 Mar '23

In contrast to backup company Backblaze, here is a report <https://blocksandfiles.com/2023/03/16/failed-disk-drives-fail-after-just-un…> from one of the ambulances at the bottom of the cliff -- a company that tries to recover data from drives after they have failed. What they find is the average working life of a failed drive is just under three years of total power-on time. (So if a drive doesn’t fail by then, it looks like its chances of surviving longer are increased.) Also worth noting that, when a drive goes bad, it doesn’t go just a little bad (say, one or two bad sectors), it tends to go significantly bad (hundreds or thousands of bad sectors). This has been my experience with bad drives too (at least, those that could still spin up and do some I/O transfers successfully). Interesting quotes: “We found that the five most durable and resilient hard drives from [the two most popular manufacturers, Western Digital and Seagate] were made before 2015. On the other hand, most of the least durable and resilient hard drives from each manufacturer were made after 2015.” and “in general, old drives seem more durable and resilient than new drives,” and “disks with CMR (conventional magnetic recording) appear more durable and resilient than those with SMR.” I think SMR drives are only used for archive purposes, because the process for writing new data onto them is somewhat convoluted and slow. Ironic, though, that an archive drive might not be that reliable ...

All-Open Source 7-Inch MNT Reform Pocket Laptop Ships In October
by Peter Reutemann 16 Mar '23

16 Mar '23

'An anonymous reader quotes a report from Ars Technica: The creators of the all-open source MNT Reform laptop are getting nearer to launching its handheld counterpart: The crowdfunding campaign for the 7-inch MNT Pocket Reform has officially launched and is also serving as a de-facto preorder system for the device. The cheapest version of the Pocket Reform starts at $899, and it's also being offered in purple for $969 or in a bundle with a 1TB SSD, carrying case, handbook, and poster for $1,299. All versions are currently slated to ship in mid-October. Like the full-size Reform, the pocket version uses open source hardware and a mechanical keyboard (buyers can choose either white or red Kalih switches). But the pocket version uses a 7-inch 1920x1200 LCD screen instead of a 12.5-inch version and comes with fewer and smaller ports (two USB-C, one micro HDMI, a microSD port, and one ix industrial mini Ethernet port). Its keyboard also comes with an individually programmable RGB backlight, and its trackball-style pointing device has been downsized to fit into the smaller design. The Pocket Reform also includes built-in Wi-Fi and Bluetooth, 128GB of built-in eMMC storage, and an expansion slot for 4G cellular connectivity. The device will also boot from microSD cards or an NVMe SSD installed in the device's M.2 slot. Its 8000 mAh batteries will allow it to run for about four hours. MNT warns in its blog post that "risks and challenges" could delay the October shipping timeline: "Pocket Reform has hundreds of electronic components. We tried to pick them so that there will be enough stock when we get around to manufacturing the boards, but it's always possible that there could be a sudden component shortage or increase in price. If that should happen, we would have to re-engineer the affected PCB and exchange the part, causing a delay in continued production. We had to adapt our products several times during the global chip crisis, so we are confident that we'll be able to work around any difficulties. Should any situation arise that would delay the estimated shipping timeline, backers will be informed promptly via project updates."' -- source: https://news.slashdot.org/story/23/03/15/2043243 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft’s File-Tainting System ’Tain’t Working
by Lawrence D'Oliveiro 15 Mar '23

15 Mar '23

Microsoft has a clever-sounding system for trying to protect Windows users from downloading malicious files: it’s called “Mark-Of-The-Web”. What it means is that any file downloaded from an untrusted source is supposed to have a special flag set in its NTFS metadata indicating that the file is not to be trusted. So any attempt by the user to perform sensitive operations on that file (e.g. execute macros from it, run it as an executable) is supposed to trigger appropriate system warnings. If the file is a .zip archive, then this mark is supposed to be propagated to all files extracted from that archive. However, it turns out this mechanism can be bypassed (surprise, surprise) <https://www.theregister.com/2022/11/01/microsoft_motw_malware_flaw/>. How can this happen? The flaw lies in the mechanism used to tell Windows to trust downloaded files, by attaching an “Authenticode” signature to them. Files without such signatures are of course untrusted and will trigger the appropriate warnings. However, by attaching an invalid signature of a particular form, you can trigger an error response from the signature-checking process that is actually interpreted as “this file is OK” <https://blog.0patch.com/2022/10/free-micropatches-for-bypassing-motw.html>. What do you call it when an attempt to add mechanisms to make a system more secure actually increases the attack surface on that system? By the way, the referenced Twitter thread discussing this vulnerability <https://twitter.com/GossiTheDog/status/1579895038523609088> seems to be saying that no Mark-Of-The-Web propagation is done for files extracted from .iso disc images. And that Microsoft uses this form for distributing its own software (Visio was mentioned) precisely to avoid the hassle of going through vetting by third-party antimalware tools.

cURL, the omnipresent data tool, is getting a 25th birthday party this month
by Peter Reutemann 13 Mar '23

13 Mar '23

'When you first start messing with the command line, it can feel like there's an impermeable wall between the local space you're messing around in and the greater Internet. On your side, you've got your commands and files, and beyond the wall, there are servers, images, APIs, webpages, and more bits of useful, ever-changing data. One of the most popular ways through that wall has been cURL, or "client URL," which turns 25 this month. The cURL tool started as a way for programmer Daniel Stenberg to let Internet Chat Relay users quickly fetch currency exchange rates while still inside their chat window. As detailed in an archived history of the project, it was originally built off an existing command-line tool, httpget, built by Rafael Sagula. A 1.0 version was released in 1997, then changed names to urlget by 2.0, as it had added in GOPHER, FTP, and other protocols. By 1998, the tool could upload as well as download, and so version 4.0 was named cURL. Over the next few years, cURL grew to encompass nearly every Internet protocol, work with certificates and encryption, offer bindings for more than 50 languages, and be included in most Linux distributions and other systems. The cURL project now encompasses both the command-line command itself and the libcurl library. In 2020, the project's history estimated the command and library had been installed in more than 10 billion instances worldwide.' -- source: https://arstechnica.com/information-technology/2023/03/curl-the-omnipresent… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Backblaze: SSDs Only Slightly More Reliable Than Hard Drives
by Lawrence D'Oliveiro 11 Mar '23

11 Mar '23

The latest storage reliability report from backup company Backblaze is out <https://blocksandfiles.com/2023/03/10/backblaze-ssd-vs-hdd/>, and they are starting to include data from their increasing use of SSDs. One result: SSDs are not much more reliable than hard drives. They find an annualized failure rate of 1.64% for HDDs, 0.98% for the solid-state ones. You could say that’s over 50% greater reliability, but it’s not enough to make any material difference to the need for a proper backup regime. Another interesting result is that SMART diagnostics from SSD controllers seem to be very inconsistent. That is to say, they are even less useful than the ones from hard drives. Not that I would bother with either.

Malware infecting widely used security appliance survives firmware updates

'Threat actors with a connection to the Chinese government are infecting a widely used security appliance from SonicWall with malware that remains active even after the device receives firmware updates, researchers said. SonicWall’s Secure Mobile Access 100 is a secure remote access appliance that helps organizations securely deploy remote workforces. Customers use it to grant granular access controls to remote users, provide VPN connections to organization networks, and set unique profiles for each employee. The access the SMA 100 has to customer networks makes it an attractive target for threat actors.

Raspberry Pi Lets You Have Your Own Global Shutter Camera For $50
by Peter Reutemann 10 Mar '23

10 Mar '23

'Global shutter sensors with no skew or distortion have been promised as the future of cameras for years now, but so far only a handful of products with that tech have made it to market. Now, Raspberry Pi is offering a 1.6-megapixel global shutter camera module to hobbyists for $50, providing a platform for machine vision, hobbyist shooting and more. From a report: The Raspberry Pi Global Shutter Camera uses a 6.3mm Sony IMX296 sensor, and requires a Raspberry Pi board with a CSI camera connector. Like other global shutter sensors, it works by pairing each pixel with an analog storage element, so that light signals can be captured and stored by all pixels simultaneously. By comparison, regular CMOS sensors read and store the light captured by pixels from top to bottom and left to right. That can cause diagonal skew on fast moving subjects, or very weird distortion on rotating objects like propellers.' -- source: https://it.slashdot.org/story/23/03/09/1241216 If only you could get hands on the Raspberry Pis themselves... ;-) Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

The SCO Lawsuit: Looking Back 20 Years Later
by Peter Reutemann 07 Mar '23

07 Mar '23

'"On March 7, 2003, a struggling company called The SCO Group filed a lawsuit against IBM," writes LWN.net, "claiming that the success of Linux was the result of a theft of SCO's technology..." Two decades later, "It is hard to overestimate how much the community we find ourselves in now was shaped by a ridiculous lawsuit 20 years ago...." It was the claim of access to Unix code that was the most threatening allegation for the Linux community. SCO made it clear that, in its opinion, Linux was stolen property: "It is not possible for Linux to rapidly reach UNIX performance standards for complete enterprise functionality without the misappropriation of UNIX code, methods or concepts". To rectify this "misappropriation", SCO was asking for a judgment of at least $1 billion, later increased to $5 billion. As the suit dragged on, SCO also started suing Linux users as it tried to collect a tax for use of the system. Though this has never been proven, it was widely assumed at the time that SCO's real objective was to prod IBM into acquiring the company. That would have solved SCO's ongoing business problems and IBM, for rather less than the amount demanded in court, could have made an annoying problem go away and also lay claim to the ownership of Unix — and, thus, Linux. To SCO's management, it may well have seemed like a good idea at the time. IBM, though, refused to play that game; the company had invested heavily into Linux in its early days and was uninterested in allowing any sort of intellectual-property taint to attach to that effort. So the company, instead, directed its not inconsiderable legal resources to squashing this attack. But notably, so did the development community as a whole, as did much of the rest of the technology industry. Over the course of the following years — far too many years — SCO's case fell to pieces. The "misappropriated" technology wasn't there. Due to what must be one of the worst-written contracts in technology-industry history, it turned out that SCO didn't even own the Unix copyrights it was suing over. The level of buffoonery was high from the beginning and got worse; the company lost at every turn and eventually collapsed into bankruptcy.... Microsoft, which had not yet learned to love Linux, funded SCO and loudly bought licenses from the company. Magazines like Forbes were warning the "Linux-loving crunchies in the open-source movement" that they "should wake up". SCO was suggesting a license fee of $1,399 — per-CPU — to run Linux.... Such an effort, in less incompetent hands, could easily have damaged Linux badly. As it went, SCO, despite its best efforts, instead succeeded in improving the position of Linux — in development, legal, and economic terms — considerably. The article argues SCO's lawsuit ultimately proved that Linux didn't contain copyrighted code "in a far more convincing way than anybody else could have." (And the provenance of all Linux code contributions are now carefully documented.) The case also proved the need for lawyers to vigorously defend the rights of open source programmers. And most of all, it revealed the Linux community was widespread and committed. And "Twenty years later, it is fair to say that Linux is doing a little better than The SCO Group. Its swaggering leader, who thought to make his fortune by taxing Linux, filed for personal bankruptcy in 2020."' -- source: https://linux.slashdot.org/story/23/03/04/0359236 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Will AMD's 'openSIL' Library Enable Open-Source Silicon Initialization With Coreboot?
by Peter Reutemann 07 Mar '23

07 Mar '23

'Formerly known as LinuxBIOS, coreboot is defined by Wikipedia as "a software project aimed at replacing proprietary firmware (BIOS or UEFI) found in most computers with a lightweight firmware." Phoronix is wondering if there's about to be a big announcement from AMD: AMD dropped a juicy tid-bit of information to be announced next month with "openSIL" [an open-source AMD x86 silicon initialization library], complete with AMD Coreboot support.... While about a decade ago AMD was big into Coreboot and at the time committed to it for future hardware platforms (2011: AMD To Support Coreboot On All Future CPUs) [and] open-source AGESA at the time did a lot of enabling around it, that work had died off. In more recent years, AMD's Coreboot contributions have largely been limited to select consumer APU/SoC platforms for Google Chromebook use. But issues around closing up the AGESA as well as concerns with the AMD Platform Security Processor (PSP) have diminished open-source firmware hopes in recent years.... For the Open Compute Project Regional Summit in Prague, there is a new entry added with a title of OSF on AMD — Enabled by openSIL (yes, folks, OSF as in "Open-Source Firmware").... [H]opefully this will prove to be a monumental shift for open-source firmware in the HPC server space. >From the talk's description: openSIL (AMD open-source x86 Silicon Initialization Library) offers the versatility, scalability, and light weight interface to allow for ease of integration with open-source and/or proprietary host boot solutions such as coreboot, UEFI and others and adds major flexibility to the overall platform design. In other words, this library-based solution simply allows a platform integrator to scale from feature rich solutions such as UEFI to slim, lightweight, and secure solutions such as coreboot. The description promises the talk will include demonstrations "highlighting system bring-up using openSIL integrated with coreboot and UEFI Host Firmware stacks on AMD's Genoa based platforms."' -- source: https://news.slashdot.org/story/23/03/06/0253208 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Quote Of The Week
by Lawrence D'Oliveiro 28 Feb '23

28 Feb '23

>From a reader comment to an article <https://www.theregister.com/2023/02/27/microsoft_ai_gpt3_data/> wherein Microsoft suggests that, since these machine-learning models are so good at generating fake and even nonsensical responses, why not use them to deliberately generate fictional sample data for testing purposes: For decades, we've written hundreds of sci-fi stories where you have an evil out-of-control AI, and that AI is hyperintelligent but can only reason along strict logical lines, and is ultimately defeated by exploiting its lack of imagination. And then, suddenly, it turns out that the AIs we can actually make have way too much imagination, and are utterly incapable of logical thought. I find this hilarious.

Who Writes Linux and Open Source Software?
by Peter Reutemann 28 Feb '23

28 Feb '23

'From an opinion piece in the Register: Aiven, an open source cloud data platform company, recently analyzed who's doing what with GitHub open source code projects. They found that the top open source contributors were all companies — Amazon Web Services, Intel, Red Hat, Google, and Microsoft.... Aiven looked at three metrics within the GitHub archives. These were the number of contributors, repositories (projects) contributed to, and the number of commits made by the contributors. These were calculated using Google Big Query analysis of PushEvents on public GitHub data. The company found that Microsoft and Google were neck-and-neck for the top spot. Red Hat is in third place, followed by Intel, then AWS, just ahead of IBM.... Red Hat is following closely behind and is currently contributing more commits than Google, with 125,012 in Q4 2022 compared to Google's 94,961. Microsoft is ahead of both, with 128,247 commits. However, regarding contributed staff working on projects, Google is leading the way with 5,757 compared to Microsoft's 5,513 and Red Hat's 3,656.... Heikki Nousiainen, Aiven CTO and co-founder, commented: "An unexpected result of our research was seeing Amazon overtake IBM to become the fifth biggest contributor." They "came late to the open source party, but they're now doubling down on its open source commitments and realizing the benefits that come with contributing to the open source projects its customers use." So, yes, open source certainly started with individual contributors, but today, and for many years before, it's company employees that are really making the code.... Aiven is far from the only one to have noticed that companies are now open source's economic engine. Jonathan Corbet, editor-in-chief of Linux Weekly News (LWN), found in his most recent analysis of Long Term Support Linux Kernel releases from 5.16 to 6.1 that a mere 7.5 percent of the kernel development, as measured by lines changed, came from individual developers. No, the real leaders were, in order: AMD; Intel; Google; Linaro, the main Arm Linux development organization; Meta; and Red Hat. The article also includes this thought-provoking quote from Aiven CTO's. "Innovation is at the heart of the open source community, but without a strong commitment from companies, the whole system will struggle. "We can see that companies are recognizing their role and supporting all who use open source."' -- source: https://news.slashdot.org/story/23/02/26/1950212 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Emacs: Comparing Two Regions From Two Files
by Lawrence D'Oliveiro 28 Feb '23

28 Feb '23

So I was compiling some useful database-related routines that I have used in various places (with MySQL and SQLite so far) over the years into a set of common modules, so that I could easily find the latest and best-tested versions of them for future projects. Then I came to a routine with two versions of a few dozen lines each, and I was trying to figure out a way of doing a diff on them without writing them out to temporary files. I have an Emacs command called “make-command-buffer”, which I can use for example to create a buffer for entering and executing shell commands, and collecting their output. It was easy enough to copy and paste both routines into the buffer, but now how do I put them both into one diff command? There is a shell feature called “here-docs”, which lets you include the standard-input data for a command directly following the command: «cmd» <<«marker» ... data ... «marker» where the «marker» is some word that does not occur in the data. But I want to have two of these, like this: diff -u <<EOD1 <<EOD2 ... version 1 ... EOD1 ... version 2 ... EOD2 You can do something like that in Perl, but it doesn’t work in the shell. Hunting around on line reminded me why: because you can only have one standard input. But in the Bash man page, there is a syntax for redirecting arbitary file descriptors, letting you have any number of heredocs. So, combining this with the ability to give a command a file name that corresponds to an already-open file descriptor, I finally got this to work: diff -u /dev/fd/8 /dev/fd/9 8<<EOD1 9<<EOD2 ... version 1 ... EOD1 ... version 2 ... EOD2

LastPass says employee’s home computer was hacked and corporate vault taken
by Peter Reutemann 28 Feb '23

28 Feb '23

'Already smarting from a breach that put partially encrypted login data into a threat actor’s hands, LastPass on Monday said that the same attacker hacked an employee’s home computer and obtained an unencrypted vault available to only a handful of company developers. Although an initial intrusion into LastPass ended on August 12, officials with the leading password manager said the threat actor “was actively engaged in a new series of reconnaissance, enumeration, and exfiltration activity” from August 12 to August 26. In the process, the unknown threat actor was able to steal valid credentials from a senior DevOps engineer and access the contents of a LastPass data vault. Among other things, the vault gave access to a shared cloud-storage environment that contained the encryption keys for customer vault backups stored in Amazon S3 buckets.' -- source: https://arstechnica.com/information-technology/2023/02/lastpass-hackers-inf… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Asahi Linux Disputes Report That Linux 6.2 Will Run on Apple M1 Chips
by Peter Reutemann 28 Feb '23

28 Feb '23

'Last week ZDNet reported Linux had added upstream support for the Apple M1 Pro, M1 Max, and M1 Ultra chips and then concluded that "newer Mac owners can look forward to running Linux on their M1-powered machines." Saturday Asahi Linux called ZDNet's story "misleading and borderline false," posting on Twitter that "You will not be able to run Ubuntu nor any other standard distro with 6.2 on any M1 Mac. Please don't get your hopes up." We are continuously upstreaming kernel features, and 6.2 notably adds device trees and basic boot support for M1 Pro/Max/Ultra machines. However, there is still a long road before upstream kernels are usable on laptops. There is no trackpad/keyboard support upstream yet. While you can boot an upstream 6.2 kernel on desktops (M1 Mac Mini, M1 Max/Ultra Mac Studio) and do useful things with it, that is only the case for 16K page size kernel builds. No generic ARM64 distro ships 16K kernels today, to our knowledge. Our goal is to upstream everything, but that doesn't mean distros instantly get Apple Silicon support. As with many other platforms, there is some integration work required. Distros need to package our userspace tooling and, at this time, offer 16K kernels. In the future, once 4K kernel builds are somewhat usable, you can expect zero-integration distros to somewhat work on these machines (i.e. some hardware will work, but not all, or only partially). This should be sufficient to add a third-party repo with the integration packages. But for out-of-the-box hardware support, distros will need to work with us to get everything right. We are already working with some, and we expect to announce official Apple Silicon support for a mainstream distro in the near future. Just not quite yet!' -- source: https://linux.slashdot.org/story/23/02/27/0457206 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'Guardian reports: Nokia has announced one of the first budget Android smartphones designed to be repaired at home allowing users to swap out the battery in under five minutes in partnership with iFixit. Launched before Mobile World Congress in Barcelona on Saturday, the Nokia G22 has a removable back and internal design that allows components to be easily unscrewed and swapped out including the battery, screen and charging port. Nokia phones manufacturer HMD Global will make "quick fix" repair guides and genuine parts available for five years via specialists iFixit, in addition to affordable professional repair options. "People value long-lasting, quality devices and they shouldn't have to compromise on price to get them. The new Nokia G22 is purposefully built with a repairable design so you can keep it even longer," said Adam Ferguson, head of product marketing for HMD Global. The G22 is partially made of recycled plastic and has a 6.53in screen, large-capacity battery, 50-megapixel camera and a fingerprint scanner. It runs Android 12 and will be supported for three years of monthly security updates and two major Android version upgrades.' -- source: https://mobile.slashdot.org/story/23/02/25/2046209 -- specs: https://www.nokia.com/phones/en_int/nokia-g-22/specs Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google Chrome's Improved Page Zoom Should Help Make the Mobile Web More Accessible
by Peter Reutemann 28 Feb '23

28 Feb '23

'Google Chrome's giving its page zoom feature a boost, which should make it more helpful for people who have difficulty reading the smaller screen on a phone. From a report: With the improved feature, you can increase the size of text, images, videos, and interactive controls on mobile web pages by up to 300 percent while preserving their original formatting. While the feature hasn't yet become available for all Chrome users, you can access it now if you download the Chrome beta on your phone or tablet. To enable the feature, tap the three dots icon in the top right corner of the browser, hit Settings > Accessibility, and then adjust the zoom level to your liking. Google will save this preference for all the sites you browse so you won't have to keep tweaking it, and will even bypass the ones that try to block zoom features. Previously, Google only allowed users to adjust text scaling options up to 200 percent.' -- source: https://it.slashdot.org/story/23/02/27/1234200 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

GCC Gets a New Frontend for Rust
by Peter Reutemann 27 Feb '23

27 Feb '23

'Slashdot reader sleeping cat shares a recent FOSDEM talk by a compiler engineer on the team building Rust-GCC, "an alternative compiler implementation for the Rust programming language." "If gccrs interprets a program differently from rustc, this is considered a bug," explains the project's FAQ on GitHub. The FAQ also notes that LLVM's set of compiler technologies — which Rust uses — "is missing some backends that GCC supports, so a gccrs implementation can fill in the gaps for use in embedded development." But the FAQ also highlights another potential benefit: With the recent announcement of Rust being allowed into the Linux Kernel codebase, an interesting security implication has been highlighted by Open Source Security, inc. When code is compiled and uses Link Time Optimization (LTO), GCC emits GIMPLE [an intermediate representation] directly into a section of each object file, and LLVM does something similar with its own bytecode. If mixing rustc-compiled code and GCC-built code in the Linux kernel, the compilers will be unable to perform a full link-time optimization pass over all of the compiled code, leading to absent CFI (control flow integrity). If Rust is available in the GNU toolchain, releases can be built on the Linux kernel (for example) with CFI using LLVM or GCC. Started in 2014 (and revived in 2019), "The effort has been ongoing since 2020...and we've done a lot of effort and a lot of progress," compiler engineer Arthur Cohen says in the talk. "We have upstreamed the first version of gccrs within GCC. So next time when you install GCC 13 — you'll have gccrs in it. You can use it, you can start hacking on it, you can please report issues when it inevitably crashes and dies horribly." "One big thing we're doing is some work towards running the rustc test suite. Because we want gccrs to be an actual Rust compiler and not a toy project or something that compiles a language that looks like Rust but isn't Rust, we're trying really hard to get that test suite working."' -- source: https://developers.slashdot.org/story/23/02/26/0543203 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft .NET 8 Will Bolster Linux Support
by Peter Reutemann 27 Feb '23

27 Feb '23

'InfoWorld: .NET 8, the next planned version of the Microsoft's open source software development platform, is set to emphasize Linux accommodations as well as cloud development and containers. A first preview of .NET 8 is available for download at dot.microsoft.com for Windows, Linux, and macOS, Microsoft said on February 21. A long-term support (LTS) release that will be supported for three years, .NET 8 is due for production availability in November, a year after the release of predecessor .NET 7. The new .NET release will be buildable on Linux directly from the dotnet/dotnet repository, using dotnet/source-build to build .NET runtimes, tools, and SDKs. This is the same build used by Red Hat and Canonical to build .NET. Over time, this capability will be extended to support Windows and macOS. Previously, .NET could be built from the source, but a "source tarball" was required from the dotnet/installer. "We are publishing Ubuntu Chiseled images with .NET 8," adds Microsoft's announcement. And when it comes to the .NET Monitor tool, "We plan to ship to dotnet/monitor images exclusively as Ubuntu Chiseled, starting with .NET 8. That's notable because the monitor images are the one production app image we publish."' -- source: https://developers.slashdot.org/story/23/02/25/1955259 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

At Least One Open Source Vulnerability Found In 84% of Code Bases, Report Finds
by Peter Reutemann 26 Feb '23

'L.Kynes shares a report from CSO Online: At a time when almost all software contains open source code, at least one known open source vulnerability was detected in 84% of all commercial and proprietary code bases examined by researchers at application security company Synopsys. In addition, 48% of all code bases analyzed by Synopsys researchers contained high-risk vulnerabilities, which are those that have been actively exploited, already have documented proof-of-concept exploits, or are classified as remote code execution vulnerabilities. The vulnerability data -- along with information on open source license compliance -- was included in Synopsys' 2023 Open Source Security and Risk Analysis (OSSRA) report (PDF), put together by the company's Cybersecurity Research Center (CyRC). "Of the 1,703 codebases that Synopsys audited in 2022, 96% of them contained open source," adds L.Kynes, citing the report. "Aerospace, aviation, automotive, transportation, logistics; EdTech; and Internet of Things are three of the 17 industry sectors included in the report that had open source in 100% of their audited codebases. In the remaining verticals, over 92% of the codebases contained open source."' -- source: https://news.slashdot.org/story/23/02/24/2035247 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

NASA Launches 'Open-Source Science Initiative', Urges Adoption of Open Science
by Peter Reutemann 26 Feb '23

26 Feb '23

'In a keynote at FOSDEM 2023, NASA's science data officer Steve Crawford explored NASA's use of open-source software. But LWN.net notes that the talk went far beyond just the calibration software for the James Webb Space Telescope and the Mars Ingenuity copter's flight-control framework. In his talk, Crawford presented NASA's Open-Source Science Initiative. Its goal is to support scientists to help them integrate open-science principles into the entire research workflow. Just a few weeks before Crawford's talk, NASA's Science Mission Directorate published its new policy on scientific information. Crawford summarized this policy with "as open as possible, as restricted as necessary, always secure", and he made this more concrete: "Publications should be made openly available with no embargo period, including research data and software. Data should be released with a Creative Commons Zero license, and software with a commonly used permissive license, such as Apache, BSD, or MIT. The new policy also encourages using and contributing to open-source software." Crawford added that NASA's policies will be updated to make it clear that employees can contribute to open-source projects in their official capacity.... As part of its Open-Source Science Initiative, NASA has started its five-year Transform to Open Science (TOPS) mission. This is a $40-million mission to speed up adoption of open-science practices; it starts with the White House and all major US federal agencies, including NASA, declaring 2023 as the "Year of Open Science". One of NASA's strategic goals with TOPS is to enable five major scientific discoveries through open-science principles, Crawford said. Interesting tidbit from the article: "In 2003 NASA created a license to enable the release of software by civil servants, the NASA Open Source Agreement. This license has been approved by the Open Source Initiative (OSI), but the Free Software Foundation doesn't consider it a free-software license because it does not allow changes to the code that come from third-party free-software projects."' -- source: https://science.slashdot.org/story/23/02/25/0337222 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Ubuntu Flavors Agree to Stop Using Flatpak
by Peter Reutemann 26 Feb '23

26 Feb '23

'Phoronix reports: While Ubuntu Linux hasn't provided Flatpak support out-of-the-box due to their preference of using their own Snap app packaging/distribution format, Ubuntu flavors/spins have to this point been able to pre-install Flatpak support if they desired. However, for the 23.04 "Lunar Lobster" cycle and moving forward, Ubuntu flavors will no longer be permitted to install Flatpak packages by default. Flatpak support for Ubuntu and its flavors will remain available in the Ubuntu archive so those wanting to install Flatpak support can easily do so post-install. This change going into effect with the 23.04 cycle is making it so no Ubuntu flavors will have Flatpak support installed by default / out-of-the-box: they are supposed to center around Debian packages and Snaps for their out-of-the-box packaging support to align with Ubuntu. >From the blog OMG Ubuntu: Ubuntu developers have agreed to stop shipping Flatpak, preinstalled Flatpak apps, and any plugins needed to install Flatpak apps through a GUI software tool in the default package set across all eight of Ubuntu's official flavors, as of the upcoming Ubuntu 23.04 release. Ubuntu says the decision will 'improve the out-of-the-box Ubuntu experience' for new users by making it clearer about what an "Ubuntu experience" is.... As far as Ubuntu is concerned, only deb and snap software is intrinsic to the 'Ubuntu experience', and that experience now needs to be offered everywhere. Flavor leads (apparently) agree, and have all agreed to mirror regular Ubuntu by not offering Flatpak features in their default install for future releases.... Flatpak will not be uninstalled or removed when user makes the upgrade to Ubuntu 23.04 from a version where Flatpak is already present.' -- source: https://linux.slashdot.org/story/23/02/25/197216 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft is Now Injecting Full-Size Edge Ads on Chrome Website
by Peter Reutemann 24 Feb '23

'Being the default out-of-the-box browser on Windows 10 and 11 makes Microsoft Edge a go-to utility for downloading Chrome or another browser. That upsets Microsoft so much that it constantly comes with more aggressive and user-hostile methods to make customers stay on Edge. An attempt to install Chrome using Edge Canary now results in the browser displaying two ads: the first (tiny one) will pop on the screen when the Chrome website loads, and the second, a humongous full-size banner, will appear once the download starts. Yikes! Microsoft also plays with words to throw shade at Chrome. The banner states that Edge uses the same technology as Chrome with the "added trust of Microsoft." The "trust" that your computer will connect to ad providers the moment you turn it on for the first time. The "trust" that Edge will shove more "recommended content" down your throat and enforce Bing without you even making a click. The "trust" that you cannot remove Edge from your computer and many more.' -- source: https://slashdot.org/story/23/02/22/1131238 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Foundation Europe Launches OpenWallet Foundation To Power Interoperable Digital Wallets
by Peter Reutemann 24 Feb '23

24 Feb '23

'The Linux Foundation's European off-shoot has formally launched the OpenWallet Foundation (OWF), a new collaborative effort designed to support interoperability between digital wallets through open source software. From a report: The launch comes some five months after the Linux Foundation first revealed plans to set up the OWF, shortly before it spun out a region-specific entity called the Linux Foundation Europe which is where the OWF will now officially reside. While the likes of PayPal, Google, and Apple are among the most recognized digital wallet providers, allowing consumers to conduct financial transactions in-store or online, digital wallets are increasingly being used to store all manner of virtual goods from student ID to driving licenses. On top of that, burgeoning technologies such as the metaverse and crypto are giving rise to greater use-cases for digital wallets. But one thing all these various environments have in common is that the incumbent digital wallets, for the most part, don't play nicely with each other: an Apple Pay die-hard can't send money to their Google Pay brethren. And that is why the OWF is setting out to create an "open source engine" that can power interoperable digital wallets across myriad use-cases including identity, payments, and storing personal credentials such as employment and education certification.' -- source: https://linux.slashdot.org/story/23/02/23/142244 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mozilla says “most top apps” on Android have misleading privacy labels
by Peter Reutemann 24 Feb '23

24 Feb '23

'It looks like trusting developers to just tell the truth about data collection on Google Play isn't working out. Just like on iOS, Android launched app privacy "nutrition labels" in the Play Store last year, with the idea being that users could quickly get a look at how much data each app collects. The obvious problem with this system is that the developers fill out the data-collection forms, and there's nothing to stop them from lying or omitting certain data-collection policies. It's no surprise, then, that when Mozilla recently audited the top apps on Google Play, it found that "most top apps" have "false or misleading" app privacy labels. Mozilla says it surveyed 40 of the Play Store's most popular apps by global downloads and found that "in nearly 80% of the apps we reviewed, we found some discrepancies between the apps’ privacy policies and the information they reported on Google’s Data Safety Form." Each app received a grade of “Poor,” “Needs Improvement,” or “OK,” with 16 out of 40 apps getting the lowest rating. Mozilla did not need to dig very deep to find flaws, saying that many apps' privacy labels openly contradict their public privacy policies. Snapchat, TikTok, and Twitter all claim "No data shared with third parties" on the Play Store but detail third-party sharing in their privacy policies. For free apps, the list of recipients earning a "poor" grade isn't very surprising: Facebook, Facebook Messenger, Facebook Lite, Snapchat, Twitter, and, the one surprise, Samsung Push Services. A lot of paid games like Minecraft make the "poor" list, too.' -- source: https://arstechnica.com/gadgets/2023/02/mozilla-says-most-top-apps-on-andro… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux 6.2: The First Mainstream Linux Kernel for Apple M1 Chips Arrives
by Peter Reutemann 22 Feb '23

22 Feb '23

'Steven Vaughan-Nichols, writing for ZDNet: Linux 6.2 was released yesterday, and Linus Torvalds described the latest Linux kernel release as, "Maybe it's not a sexy LTS release like 6.1 ended up being, but all those regular pedestrian kernels want some test love too." For once, I disagree with Torvalds. By adding upstream support for the Apple M1 Pro, M1 Max, and M1 Ultra chips, newer Mac owners can look forward to running Linux on their M1-powered machines. And, for techies, that's sexy. Getting Linux to run on the M1 family wasn't easy. When these high-powered ARM chips first arrived, Torvalds told me in an exclusive interview that he'd like to run Linux on these next-generation Macs. But, while he'd been "waiting for an ARM laptop that can run Linux for a long time," he worried, saying, "The main problem with the M1 for me is the GPU and other devices around it because that's likely what would hold me off using it because it wouldn't have any Linux support unless Apple opens up."' -- source: https://linux.slashdot.org/story/23/02/21/0418215 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

RNZ--No More Ogg?
by Lawrence D'Oliveiro 21 Feb '23

21 Feb '23

Some years ago, Radio New Zealand started making its audio downloads available in Ogg Vorbis format, as an alternative to MP3. As I recall, this coincided with a visit from Richard Stallman, and no doubt his persuasiveness had something to do with it. (Checking the timestamps on my downloads, Stallman was interviewed by Kim Hill on “Nine to Noon” on 9th August 2008.) I was revisiting the Mediawatch page after a long absence <https://www.rnz.co.nz/national/programmes/mediawatch>, and I see they have reverted to MP3-only format for their downloads now. Were people being confused by .ogg files? All the open-source players can handle them, so what players were they trying to use?

Google Chrome's Latest Version Includes Tools To Address Its Memory Hog Problem
by Peter Reutemann 21 Feb '23

21 Feb '23

'Google has released optimization features designed to improve battery life and memory usage on machines running the latest version of its Chrome desktop web browser. From a report: Chrome's new Energy Saver and Memory Saver modes were first announced in December last year alongside the release of Chrome 108, and now as noted by Android Police, the two optimization utilities are starting to roll out globally onto Chrome 110 desktops for Mac, Windows, and Chromebooks.

Purism Combines Phone Docking Station and Laptop Shell For Lapdock Kit
by Peter Reutemann 21 Feb '23

21 Feb '23

'Their video says it all. Its official page brags it can "Transform your Librem 5 into a laptop." But it all apparently started because Purism is proud that their Librem 5 line of phones run "the same desktop applications as our full-sized computers, just on a smaller screens," according to the announcement by Purism president Kyle Rankin: When only using the Librem 5 in its mobile form factor, it's easy to overlook that this is happening, as adaptive applications morph to fit the smaller screen.... It's only when you dock the Librem 5 that you really experience the power of convergence.... We have wanted to provide a lapdock kit to customers for some time now, and I've personally evaluated almost all of the options available to pick which one would best showcase the Librem 5. I'm so happy to announce that today we are launching our new Lapdock Kit and in this post I will explain a bit more about what's included and why it's a great companion to a Librem 5 or Librem 5 USA. A lapdock is a docking station (or "dock") combined with a laptop shell. One approach to docking your Librem 5 is to get a USB-C hub and attach it to a power supply, monitor, keyboard and mouse, and we even sell those accessories for our Librem 5. Now imagine taking all of those components and squeezing them into a laptop form-factor, add a battery to power it, and you have a lapdock. >From the outside a lapdock looks no different from a standard laptop, but the difference is that a lapdock has no CPU, RAM or storage of its own. Instead, it uses the Librem 5 as the computer. Once docked, the Librem 5's screen extends to the lapdock screen, and you can use the keyboard and mouse on the lapdock to drag windows back and forth between screens. All of the applications are running on the Librem 5 and once docked, it behaves like a laptop running PureOS. Even better, the lapdock's battery charges the Librem 5 while it's docked, extending its run time. After evaluating a number of different options, we have decided to offer the Nexdock 360 in our Lapdock Kit.... The Lapdock Kit allows you to realize the power of having all of your apps and all of your data in one device that can fit in your pocket and act like a phone when you need it to, but then transform into a laptop when you want to type out an email, do some image editing or watch a video on a larger screen. The Lapdock Kit also allows you to run thousands of other desktop applications that haven't yet been updated to adapt to a phone's screen. Traditional Linux applications like the full LibreOffice suite, GIMP, Wireshark, Gqrx and many others run well on the Librem 5 with the addition of the Lapdock Kit's extra screen real estate. "It demonstrates why we refer to the Librem 5 as a mobile computer in your pocket, and not just as a phone."' -- source: https://mobile.slashdot.org/story/23/02/20/0518253 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Email Security: Still A Work In Progress
by Lawrence D'Oliveiro 20 Feb '23

20 Feb '23

The various mechanisms to try to block forged email addresses (whether just for spam or for more nefarious purposes) still have holes in them, according to <https://www.theregister.com/2023/02/19/forwarding_email_security/>. For example, you can create an account on a major email service like outlook.com, enable forwarding, and put a spoofed address into its “allow list”. Then when a message comes in for that account purporting to come from that spoofed address, it bypasses the authenticity check and goes straight out again, with the spoofed from-address. And this one weird trick† works--or used to work--for a number of other major email providers, as well. To me, the whole plethora of these message-validation mechanisms--SPF, DKIM, DMARC, ARC and who knows what else--is just bewildering. Which is why I have yet to implement any of them for my own domain. What’s worth doing? Where do you start? †So sue me.

KDE Plasma 5.27 Released
by Peter Reutemann 15 Feb '23

15 Feb '23

'Plasma is a popular desktop environment, which is also powering the desktop mode on the Steam Deck hand-held gaming console. Today, KDE Community announced release of KDE Plasma 5.27, a Long Term Support (LTS) release and the final release in the Plasma 5 series which is based on Qt 5. This release brings a welcome wizard, which will guide you through setting up the desktop, and a new tiling system for KWin window manager, allowing you to set up custom tile layouts and resize adjacent tiled windows simultaneously. The settings for touch-enabled devices such as touchscreens and drawing tablets have been improved and expanded. For those lucky owners of Valve's Steam Deck gaming console, Discover can now perform system updates from within the desktop. Digital Clock desktop widget can now show the Hebrew calendar in its calendar view, and the Media Player widget is now touch-sensitive. The Bluetooth widget shows the battery status of connected devices when you hover the cursor over it. Those of you who use multiple monitors should benefit greatly from a major overhaul of how Plasma handles them. KDE Plasma now comes with Flatpak permissions settings integrated into the System Settings app. For details and other new features and improvements be sure to check out the full announcement.' -- source: https://tech.slashdot.org/story/23/02/14/2226234 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Is Bing Getting Sentient?
by Lawrence D'Oliveiro 15 Feb '23

15 Feb '23

Microsoft’s AI-powered “Bing Chat” service doesn’t seem to be reacting well to attempts to hack it <https://arstechnica.com/information-technology/2023/02/ai-powered-bing-chat…>. It has started arguing with users, and even showed signs of being upset when they mention its code name “Sydney”. One user asked it about prompt-injection attacks, to which it replied that it was immune to them. Then, when pointed to the previous Ars Technica article detailing exactly such an exploit, it basically went into full denial mode, claiming that “the article is published by a source that has a history of spreading misinformation and sensationalism”. Screenshots of other less-than-wholesome interactions are derided as “not authentic” and “edited or fabricated”. I think the psychological term for such flat-out denials of reality is “psychosis”. And looks like we finally have our real-life HAL 9000, just about 31 years late. Just make sure it is never connected to any life-support systems...

The Mastodon Bump Is Now a Slump
by Peter Reutemann 14 Feb '23

14 Feb '23

'The fall in Mastodon's popularity suggests the decentralized platform is not a replacement for mainstream services. An anonymous reader shares a report: Twitter users put Mastodon usernames in their handles and trumpeted their migration. The new traffic knocked many Mastodon instances, or servers, offline. In less than two months, Mastodon's monthly active users climbed from 380,000 to more than 2.5 million. But not everyone stuck around. Mastodon's active monthly user count dropped to 1.4 million by late January. It now has nearly half a million fewer total registered users than at the start of the year.

Is Windows 11 Spyware? Microsoft Defends Sending User Data to Third Parties
by Peter Reutemann 13 Feb '23

13 Feb '23

'A report from Tom's Hardware: According to the PC Security Channel (via TechSpot), Microsoft's Windows 11 sends data not only to the Redmond, Washington-based software giant, but also to multiple third parties. To analyze DNS traffic generated by a freshly installed copy of Windows 11 on a brand-new notebook, the PC Security Channel used the Wireshark network protocol analyzer that reveals precisely what is happening on a network. The results were astounding enough for the YouTube channel to call Microsoft's Windows 11 "spyware." As it turned out, an all-new Windows 11 PC that was never used to browse the Internet contacted not only Windows Update, MSN and Bing servers, but also Steam, McAfee, geo.prod.do, and Comscore ScorecardResearch.com. Apparently, the latest operating system from Microsoft collected and sent telemetry data to various market research companies, advertising services, and the like. When Tom's Hardware contacted Microsoft, their spokesperson argued that flowing data is common in modern operating systems "to help them remain secure, up to date, and keep the system working as anticipated." "We are committed to transparency and regularly publish information about the data we collect to empower customers to be more informed about their privacy."' -- source: https://tech.slashdot.org/story/23/02/12/059214 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'Mycroft' Open-Source Voice Assistant Out of Funds, Can't Fulfill Remaining Kickstarter Rewards
by Peter Reutemann 13 Feb '23

13 Feb '23

'In 2019 Slashdot covered Mycroft, an open-source voice assistant for Linux-based devices (including Raspberry Pi boards). But this week the company's CEO posted on Kickstarter that "without immediate new investment, we will have to cease development by the end of the month.... "We will still be shipping all orders that are made through the Mycroft website, because these sales directly cover the costs of producing and shipping the products. However we do not have the funds to continue fulfilling rewards from this crowdfunding campaign, or to even continue meaningful operations." The announcement details Mycroft's long, strange trip, from a hardware-focused partner that couldn't provide stable hardware to their switch to using off-the-shelf parts — followed by supply chain disruptions (with hefty import and manufacturing fees): The best plan we could devise to fulfill the remaining campaign rewards was to use the slim margins we have on new sales to cover the increased costs of hardware production. With that plan in mind, we pushed forward and started production. We got plastic injection molds cast. We started printing custom PCBs. We engaged audio engineers to optimize the quality and volume of the sound output. We got the device FCC and CE approved. Many of these steps took multiple iterations to get right, and there are many more things that I'm glossing over. All up this costs — a lot of money. Far more than the total contributions from the campaign, which is why I personally committed so much additional funding. I could see a clear way forward that strengthened Mycroft as a project, as a business, and as a community. So what went wrong? The single most expensive item that I could not predict was our ongoing litigation against the non-practicing patent entity that has never stopped trying to destroy us. If we had that million dollars we would be in a very different state right now. With so much of our focus on hardware, and less funding to devote to improving our software — the quality and features available on the Mark II at launch were clearly underwhelming. It is more robust and stable than it has ever been, but this came at the cost of fewer new features. That in turn I believe has resulted in less than flattering reviews, and little mainstream coverage. The hardware itself has proven itself to be a solid base to work from, but without good reviews you get less sales, and without strong sales, the plan doesn't work.' -- source: https://news.slashdot.org/story/23/02/12/0413229 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

A Developer is Reimplementing GNU's Core Utilities in Rust

'A Rust-based re-implementation of GNU core utilities like cp and mv is "reaching closer to parity with the widely-used GNU upstream and becoming capable of taking on more real-world uses," reports Phoronix: Debian developer Sylvestre Ledru [also an engineering director at Mozilla] began working on uutils during the COVID-19 pandemic and presented last week at FOSDEM 2023 on his Coreutils replacement effort. With uutils growing into increasingly good shape, it's been packaged up by many Linux distributions and is also used now by "a famous social network via the Yocto project...." The goals with uutils are to try to create a drop-in replacement for GNU Coreutils, strive for good cross-platform support, and easy testing. Ledru's initial goals were about being able to boot Debian, running the most popular packages, building key open-source software, and all-around it's been panning out to be a great success....

GitHub and EFF Back YouTube Ripper In Legal Battle With the RIAA
by Peter Reutemann 11 Feb '23

11 Feb '23

'GitHub and digital rights group EFF have filed briefs supporting stream-ripping site Yout.com in its legal battle with the RIAA. GitHub warns that the lower court's decision threatens to criminalize the work of many other developers. The EFF, meanwhile, stresses that an incorrect interpretation of the DMCA harms people who use stream-rippers lawfully. TorrentFreak reports: In 2020, YouTube ripper Yout.com sued the RIAA, asking a Connecticut district court to declare that the site does not violate the DMCA's anti-circumvention provision. The music group had previously used DMCA takedown notices to remove many of Yout's appearances in Google's search results. This had a significant impact on revenues, the site argued, adding that it always believed it wasn't breaking any laws and hoped the court would agree. Last October, the Connecticut district court concluded that Yout had failed to show that it doesn't circumvent YouTube's technological protection measures. As such, it could be breaking the law. Yout operator Johnathan Nader opted to appeal the decision. Nader's attorneys filed their opening brief (PDF) last week at the Court of Appeals for the Second Circuit, asking it to reverse the lower court's decision. The YouTube ripper is not the only party calling for a reversal. Yesterday, Microsoft-owned developer platform GitHub submitted an amicus brief that argues for the same. And in a separate filing, the EFF also agrees that the lower court's decision should be overturned. GitHub's brief starts by pointing out that the company takes no position on the ultimate resolution of this appeal, nor does it side with all of Yout's arguments. However, it does believe that the lower court's interpretation of the DMCA is dangerous. The district court held that stream rippers can violate the DMCA's anti-circumvention provision. The court noted that these tools allow people to download video and audio from YouTube, despite the streaming platform's lack of a download button. According to GitHub, this conclusion is premature, dangerous, and places other software types at risk. In the present lawsuit, GitHub reiterates that stream-ripping tools should not be outlawed. The fact that YouTube doesn't have a download button doesn't mean that tools that enable people to download videos circumvent technological access restrictions. "YouTube's decision not to provide its own 'download' button, however, is not a restriction on access to works. It merely affects how users experience them," GitHub writes. If the court order is allowed to stand, GitHub warns that a broad group of developers could be exposed to criminal liability, effectively chilling technological innovation. YouTube download tools are not the only types of software at risk, according to GitHub. There are many others that affect 'how users experience' online websites. These could also be seen as problematic, based on the district court's expansive interpretation of the DMCA. These widely accepted tools could put their creators at risk if the DMCA is interpreted too strictly, GitHub warns. The Electronic Frontier Foundation (EFF) also submitted an amicus curiae brief (PDF) yesterday. The digital rights group takes interest in copyright cases, particularly when they get in the way of people's ability to freely use technology. In this instance, EFF points out that stream-rippers such as Yout.com provide a neutral technology with plenty of legal uses. They can be used for infringing purposes, but that's also true for existing technologies -- the printing press, for example. "Like every reproduction technology -- from the printing press to the smartphone -- these programs, colloquially called 'streamrippers,' have important lawful uses as well as infringing ones. "Video creators, educators, journalists, and human rights organizations all depend on the ability to make copies of user-uploaded videos," EFF adds. In common with GitHub, EFF notes that the absence of a download button on YouTube doesn't imply that download tools automatically violate the DMCA, especially when there are no effective download restrictions on the platform. [...] According to EFF, Yout and similar tools provide the same functions as video cassette recorders once did. They allow people to make copies of videos that are posted publicly by their creators. In addition, these tools are vital for some reporters and useful to creatives who use them for future work.

The Future Of Thunderbird
by Peter Reutemann 10 Feb '23

10 Feb '23

'Thunderbird blog: Before we really dig in, let's start with the future. We believe it's a bright one! With this year's release of Thunderbird 115 "Supernova," we're doing much more than just another yearly release. It's a modernized overhaul of the software, both visually and technically. Thunderbird is undergoing a massive rework from the ground up to get rid of all the technical and interface debt accumulated over the past 10 years. This is not an easy task, but it's necessary to guarantee the sustainability of the project for the next 20 years. Simply "adding stuff on top" of a crumbling architecture is not sustainable, and we can't keep ignoring it. Throughout the next 3 years, the Thunderbird project is aiming at these primary objectives: 1. Make the code base leaner and more reliable, rewrite ancient code, remove technical debt. 2. Rebuild the interface from scratch to create a consistent design system, as well as developing and maintaining an adaptable and extremely customizable user interface. 3. Switch to a monthly release schedule. Inside those objectives there are hundreds of very large steps that need to happen, and achieving everything will require a lot of time and resources.' -- source: https://it.slashdot.org/story/23/02/09/1651259 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

US NIST Unveils Winning Encryption Algorithm For IoT Data Protection
by Peter Reutemann 09 Feb '23

09 Feb '23

'The National Institute of Standards and Technology (NIST) announced that ASCON is the winning bid for the "lightweight cryptography" program to find the best algorithm to protect small IoT (Internet of Things) devices with limited hardware resources. BleepingComputer reports: ASCON was selected as the best of the 57 proposals submitted to NIST, several rounds of security analysis by leading cryptographers, implementation and benchmarking results, and feedback received during workshops. The whole program lasted for four years, having started in 2019. NIST says all ten finalists exhibited exceptional performance that surpassed the set standards without raising security concerns, making the final selection very hard. ASCON was eventually picked as the winner for being flexible, encompassing seven families, energy efficient, speedy on weak hardware, and having low overhead for short messages. NIST also considered that the algorithm had withstood the test of time, having been developed in 2014 by a team of cryptographers from Graz University of Technology, Infineon Technologies, Lamarr Security Research, and Radboud University, and winning the CAESAR cryptographic competition's "lightweight encryption" category in 2019. Two of ASCON's native features highlighted in NIST's announcement are AEAD (Authenticated Encryption with Associated Data) and hashing. AEAD is an encryption mode that provides confidentiality and authenticity for transmitted or stored data, combining symmetric encryption and MAC (message authentication code) to prevent unauthorized access or tampering. Hashing is a data integrity verification mechanism that creates a string of characters (hash) from unique inputs, allowing two data exchange points to validate that the encrypted message has not been tampered with. Despite ASCON's lightweight nature, NIST says the scheme is powerful enough to offer some resistance to attacks from powerful quantum computers at its standard 128-bit nonce. However, this is not the goal or purpose of this standard, and lightweight cryptography algorithms should only be used for protecting ephemeral secrets.

Android 14 Preview 1 is Out, Will Officially Ban Installation of Old Apps
by Peter Reutemann 09 Feb '23

09 Feb '23

'Android 14 is here -- or the first preview is, at least. From a report: Google is kicking off the months-long developer preview process for Android's latest version, which will get a final release in the second half of the year. Even with multiple previews, Google likes to keep the final set of Android features under wraps at least until its I/O conference in May, so we can't look at the features here to determine the scope of Android 14. These are just some of the features Google wants developers to have a head start on. The biggest news is that Android 14 will block the installation of old Android apps. As Android changes over the years, new APIs and increased security, privacy, or background processing restrictions could break old apps, but Android's backward-compatibility system keeps these old apps running. Apps can declare the newest version of Android they support via a "Target SDK" flag. To prevent old apps from breaking, new features and app restrictions in, say, Android 12 only apply to apps that target Android 12 or above. Older apps will continue to run with the older set of restrictions they're used to. (A different setting, called "Minimum SDK," determines if a new app can run on an old Android OS.) The system works great for honest developers, but if you're building a piece of malware, it's an easy decision to target a very old version of Android. While you'll get access to fewer features, you'll also be subject to fewer security and privacy restrictions. For the first time, Android 14 will close this malware loophole by simply refusing to install old apps. The cutoff point is generous enough that it shouldn't cause anyone problems; any app targeting the 8-year-old Android 6.0 or below will be blocked. Google says it picked Android 6 because it's the version that introduced runtime permissions, the allow/deny boxes that pop up asking for things like camera access. In addition, "some malware apps use a targetSdkVersion of [Android 5.1] to avoid being subjected to the runtime permission model introduced in 2015 by Android 6.0," Google said.' -- source: https://tech.slashdot.org/story/23/02/08/1919253 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux 6.1 Officially Promoted To Being An LTS Kernel
by Peter Reutemann 09 Feb '23

09 Feb '23

'Linux 6.1 was widely anticipated to be a Long-Term Support (LTS) kernel with normally the last major release series for the calendar year normally promoted to LTS status. Greg Kroah-Hartman as the Linux stable maintainer went ahead today and formally recognized Linux 6.1 as the 2022 LTS kernel. From a report: Greg KH was planning on Linux 6.1 being LTS given its December debut. But he was waiting on feedback from kernel stakeholders over their test results with Linux 6.1 and plans around using Linux 6.1 for the long-term. He's finally collected enough positive responses -- along with co-maintainer Sasha Levin -- that there is confidence in maintaining Linux 6.1 as an LTS series. As of now the plan is on maintaining Linux 6.1 through December 2026, which is just a few months longer than the current Linux 5.15 LTS series that will be maintained through October 2026. We'll see over time if Linux 6.1 ends up potentially being maintained for the longer six-year LTS period that would put it through 2028. However, the number of Linux LTS series being maintained in tandem is growing and will ultimately depend upon how much these kernels are used by major industry players and how much commitment there is for testing of the point release candidates, etc.' -- source: https://linux.slashdot.org/story/23/02/08/174210 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mozilla, Like Google, is Looking Ahead To the End of Apple's WebKit Rule
by Peter Reutemann 08 Feb '23

08 Feb '23

'Mozilla is planning for the day when Apple will no longer require its competitors to use the WebKit browser engine in iOS. From a report: Mozilla conducted similar experiments that never went anywhere years ago but in October 2022 posted an issue in the GitHub repository housing the code for the iOS version of Firefox that includes a reference to GeckoView, a wrapper for Firefox's Gecko rendering engine. Under the current Apple App Store Guidelines, iOS browser apps must use WebKit. So a Firefox build incorporating Gecko rather than WebKit currently cannot be distributed through the iOS App Store. As we reported last week, Mozilla is not alone in anticipating an iOS App Store regime that tolerates browser competition. Google has begun work on a Blink-based version of Chrome for iOS. The major browser makers -- Apple, Google, and Mozilla -- each have their own browser rendering engines. Apple's Safari is based on WebKit; Google's Chrome and its open source Chromium foundation is based on Blink (forked from WebKit a decade ago); and Mozilla's Firefox is based on Gecko. Microsoft developed its own Trident rendering engine in the outdated Internet Explorer and a Trident fork called EdgeHTML in legacy versions of Edge but has relied on Blink since rebasing its Edge browser on Chromium code.' -- source: https://news.slashdot.org/story/23/02/07/1733204 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Carbonyl: a New Graphical Web Browser in Your Linux Terminal
by Peter Reutemann 07 Feb '23

'Long-time Slashdot reader destinyland writes: Someone made a Chromium fork... for your terminal. The terminal-based browser Carbonyl "adheres to, and is compatible with modern standards," writes MUO, "meaning that pages behave as they should, and you can even watch streaming video, within the Linux terminal!" But best of all, "Pages connect and render in an instant—seemingly quicker than a desktop GUI browser, and every page we visited was rendered correctly." >From the article: There are a bunch of good reasons to browse the internet from the comfort of your terminal. It could be that eschewing the bloat of X.org and Wayland, a terminal is all you have. Maybe you like SSHing into remote machines and browsing the internet from there. Perhaps you, like us, just really, really like terminals. Whatever the reason, your choices of web browsers have, until recently, been limited, and your experience of the world wide web has been a janky, barely-functional one.... We tested Carbonyl in a range of Linux terminals, including the XFCE terminal. GNOME terminal, kitty, and the glorious Cool Retro Terminal. Carbonyl was smooth, fast, and flawless in all of them. We even connected to our Raspberry Pi via SSH in CRT, and ran Carbonyl remotely, watching Taylor Swift music videos on YouTube. No problem. And yes, you can use it to play DOOM.' -- source: https://linux.slashdot.org/story/23/02/04/0246248 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft Swears It's Not Coming For Your Data With Scan For Old Office Versions
by Peter Reutemann 07 Feb '23

07 Feb '23

'Microsoft wants everyone to know that it isn't looking to invade their privacy while looking through their Windows PCs to find out-of-date versions of Office software. From a report: In its KB5021751 update last month, Microsoft included a plan to scan Windows systems to smoke out those Office versions that are no longer supported or nearing the end of support. Those include Office 2007 (which saw support end in 2017) and Office 2010 (in 2020) and the 2013 build (this coming April). The company stressed that it would run only one time and would not install anything on the user's Windows system, adding that the file for the update is scanned to ensure it's not infected by malware and is stored on highly secure servers to prevent unauthorized changes to it. The update caused some discussion among users, at least enough to convince Microsoft to make another pitch that it is respecting user privacy and won't access private data despite scanning their systems. The update collects diagnostic and performance data so that it can determine the use of various versions of Office and how to best support and service them, the software maker wrote in an expanded note this week. The update will silently run once to collect the data and no files are left on the user's systems once the scan is completed.' -- source: https://yro.slashdot.org/story/23/02/06/1753258 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

EU's Proposed CE Mark for Software Could Have Dire Impact on Open Source
by Peter Reutemann 31 Jan '23

31 Jan '23

'The EU's proposed Cyber Resilience Act (CRA), which aims to "bolster cybersecurity rules to ensure more secure hardware and software products," could have severe unintended consequences for open source software, according to leaders in the open source community. From a report: The proposed Act can be described as CE marking for software products and has four specific objectives. One is to require manufacturers to improve the security of products with digital elements "throughout the whole life cycle." Second is to offer a "coherent cybersecurity framework" by which to measure compliance. Third is to improve the transparency of digital security in products, and fourth is to enable customers to "use products with digital elements securely." The draft legislation includes an impact assessment that says "for software developers and hardware manufacturers, it will increase the direct compliance costs for new cybersecurity requirements, conformity assessment, documentation and reporting obligations." This extra cost is part of a total cost of compliance, including the burden on businesses and public authorities, estimated at EUR 29 billion ($31.54 billion), and consequent higher prices for consumers. However, the legislators foresee a cost reduction from security incidents estimated at EUR 180 to 290 billion annually. The question is though: how can free software developers afford the cost of compliance, when lack of funding is already a critical issue for many projects? Mike Milinkovich, director of the Eclipse Foundation, said it is "deeply concerned that the CRA could fundamentally alter the social contract which underpins the entire open source ecosystem: open source software provided for free, for any purpose, which can be modified and further distributed for free, but without warranty or liability to the authors, contributors, or open source distributors. Legally altering this arrangement through legislation can reasonably be expected to cause unintended consequences to the innovation economy in Europe."' -- source: https://news.slashdot.org/story/23/01/26/1211223 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Customer Conned Out Of Deposit, Company Liable
by Lawrence D'Oliveiro 30 Jan '23

30 Jan '23

A malicious third party intercepted email messages between a carpeting company and a customer, and was able to send a fake email asking for a deposit to the customer with all the right contact details, but the wrong bank account number <https://www.nzherald.co.nz/lifestyle/hacker-intercepts-carpet-companys-emai…>. And now the Disputes Tribunal has ruled that, since the email looked completely convincing, with the right personal details and everything, it was not reasonable to expect the customer to be suspicious or to want to double-check. And so the company had to wear the cost of the scam.

Intel Kills Its RISC-V Development Environment
by Lawrence D'Oliveiro 30 Jan '23

30 Jan '23

Intel is abandoning its “Pathfinder” project <https://www.theregister.com/2023/01/30/intel_ris_v_pathfinder_discontinued/> which was an integrated environment for doing development targeted at RISC-V processors. What does this mean for RISC-V? Not a lot, I would say. What does it mean for Intel? I think the basic problem here is the same as with its attempts to move into ARM: you have a high-volume, low-margin business where a company that has grown fat on not-so-high-volume, quite high-margin x86 processors was never going to be able to compete.

Jeremy Allison Laid Off From Google
by Lawrence D'Oliveiro 28 Jan '23

28 Jan '23

Seems the latest round of layoffs from Google has hit its open-source projects particularly hard, according to Steven J Vaughan-Nichols <https://www.theregister.com/2023/01/27/google_open_source/>. The one name that immediately caught my eye was Jeremy Allison, one of the chief brains behind Samba <https://www.samba.org/>. Before joining Google, he worked at Novell. He left there in 2006 because he objected to a deal Novell made with Microsoft which was effectively a patent licence for Free software (something which the GPL doesn’t allow) <https://www.zdnet.com/article/in-case-you-missed-it-part-1-jeremy-allison-f…>. While waiting to see where else he turns up, it is worth revisiting this essay <https://www.samba.org/samba/news/articles/low_point/tale_two_stds_os2.html> from shortly before that time, where he does a comparison between the Microsoft Windows and POSIX APIs, and why there can be so many independent, yet interoperable implementations of the latter, and why there can be only one of the former (though the WINE project continues to try to change that).

Consumer Reports Looks At Memory Safety
by Lawrence D'Oliveiro 27 Jan '23

27 Jan '23

The nonprofit Consumer Reports foundation has done a study of, of all things, memory safety in computer software <https://www.theregister.com/2023/01/26/memory_safety_mainstream/>. It apparently came to the need for this after putting together a consumer-focused guide to online security. Seems like greater adoption of the Rust programming language is becoming a key part of improving the situation. Asked about C++ creator Bjarne Stroustrup's assertion that ISO standard C++ can be memory safe when rules are enforced with static analysis, [Josh Aas, of the nonprofit Internet Security Research Group] expressed skepticism. "In a very theoretical sense that ignores the practicalities of the real world, that might be true," he said. "It might very theoretically be practically possible to write memory safe C++. But it's just not how things work in our world. There are just better ways to do that. C++ was not designed from the ground up to offer memory safety."

Android 14 Set To Block Certain Outdated Apps From Being Installed
by Peter Reutemann 25 Jan '23

25 Jan '23

'To help reduce the potential for malware, Android 14 will begin fully blocking the installation of apps that target outdated versions of Android. 9to5Google reports: For years now, the guidelines for the Google Play Store have ensured that Android developers keep their apps updated to use the latest features and safety measures of the Android platform. Just this month, the guidelines were updated, requiring newly listed Play Store apps to target Android 12 at a minimum. Up to this point, these minimum API level requirements have only applied to apps that are intended for the Google Play Store. Should a developer wish to create an app for an older version, they can do so and simply ask their users to sideload the APK file manually. Similarly, if an Android app hasn't been updated since the guidelines changed, the Play Store will continue serving the app to those who have installed it once before. According to a newly posted code change, Android 14 is set to make API requirements stricter, entirely blocking the installation of outdated apps. This change would block users from sideloading specific APK files and also block app stores from installing those same apps. Initially, Android 14 devices will only block apps that target especially old Android versions. Over time though, the plan is to increase the threshold to Android 6.0 (Marshmallow), with Google having a mechanism to "progressively ramp [it] up." That said, it will likely still be up to each device maker to decide the threshold for outdated apps or whether to enable it at all. The report notes that it'll still be possible to install an outdated version of an app "through a command shell, by using a new flag."' -- source: https://tech.slashdot.org/story/23/01/24/225226 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google’s Fuchsia OS was one of the hardest hit by last week’s layoffs
by Peter Reutemann 24 Jan '23

24 Jan '23

'Google is still reeling from the biggest layoff in company history last Friday. Earlier cost cuts over the past six months have resulted in several projects being shut down or deprioritized at Google, and it's hard to fire 12,000 people without some additional projects taking a hit. The New York Times has a report about which divisions are being hit the hardest, and a big one is Google's future OS development group, Fuchsia. While the overall company cut 6 percent of its employees, the Times pointed out that Fuchsia saw an outsize 16 percent of the 400-person staff take a hit. While it's not clear what that means for the future of the division, the future of Fuchsia's division has never really been clear. Fuchsia has been a continuous mystery inside Google since it first saw widespread press coverage in 2017. Google rarely officially talks about it, leaving mostly rumors and Github documentation for figuring out what's going on. The OS isn't a small project, though—it's not even based on Linux, opting instead to use a custom, in-house kernel, so Google really is building an entire OS from scratch. Google actually ships the OS today to consumers in its Nest smart displays, where it replaced the older Cast OS. The in-place operating system swap was completely invisible to consumers compared to the old OS, came with zero benefits, and was never officially announced or promoted. There's not much you can do with it on a locked-down smart display, so even after shipping, Fuchsia is still a mystery. The biggest questions surrounding Fuchsia are: "Why does this exist, and what are its goals?" Is Fuchsia an eventual replacement for Android or Chrome OS? Around 2018, when we first got Fuchsia running on a Pixelbook, the source code documentation for the custom kernel said it "targets modern phones and modern personal computers with fast processors," which certainly made it sound like an Android and/or Chrome OS successor being built for flagship devices. That early codebase also included graphical user interfaces for PCs and phones, further driving home that this was a consumer OS. After Fuchsia got some initial publicity, it removed its public interface code. 2018 also saw a foundational Bloomberg report calling Fuchsia "a successor to Android," and saying the team planned to launch on smart speakers in 2021 (which was spot on) and would later move into phones and laptops in 2023. Even the name "Fuchsia" was a reference to Apple projects some members of the team had been involved with. "Pink" was the codename for a canceled successor to classic Mac OS, and "Purple" was the codename for the iPhone OS. The color Fuchsia is a mix of pink and purple, so this all sounded very ambitious.' -- source: https://arstechnica.com/gadgets/2023/01/big-layoffs-at-googles-fuchsia-os-c… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

83% of GNOME Users Installed Extensions, Survey Shows
by Peter Reutemann 24 Jan '23

24 Jan '23

'Last summer GNOME invited people to voluntarily run the tool gnome-info-collect on their systems to send back (non-sensitive/non-identifiable) data about their system configurations. 2,560 people ran the tool, and they're now releasing the data. Here's the distribution of distros for all 2,560 respondents: Fedora: 1,376 (54.69%) Arch: 469 (18.64%) Ubuntu: 267 (10.61%) Manjaro: 140 (5.56%) EndeavourOS: 66 (2.62%) Debian: 44 (1.75%) openSUSE: 38 (1.51%) Pop! 38 (1.51%) Other: 78 (3.10%) And the breakdown of hardware manufacturers (top four): Lenovo: 516 (23.54%) Dell: 329 (15.01%) ASUS: 261 (11.91%) HP: 223 (10.17%) The site OMG! Linux pointed out that 90% of systems had Flatpak installed — (though it's enabled by default on Fedora, which was 54.69% of all the respondents). Some other interesting stats they noticed: - Most common default browser: Firefox (73.14%), Chrome (11.64%), Brave (4.76%). [Microsoft Edge was the default browser on 37 systems (1.51%) ] - 83% of users have at least one (non-default) GNOME extension installed - 'App Indicator' is the most popular extension (by 43% of those using extensions) - GSConnect, User Themes, and Dash to Panel/Dock also widely used - Most popular desktop apps: GIMP (58.48%), VLC (53.71%), Steam (53.40%) [...] The popularity of GNOME extensions will surprise no-one. It is a solid indicator that the existing GNOME extension system is good at doing what it's there to: let users augment and extend their system in the ways they want. GNOME's report adds that "it's exciting to see the popularity of new GNOME apps like Flatseal, To Do, Bottles, and Fragments." One other interesting stat from their report: 55% of the participants were using Online Accounts, with Google the most common one added, followed by Nextcloud and Microsoft. But "Some of the account types had very little usage at all, with Foursquare, Facebook, Media Server, Flickr and Last.fm all being active on less than 1% of systems."' -- source: https://tech.slashdot.org/story/23/01/23/0355247 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Which Performs Better on Linux: Firefox or Chrome?
by Peter Reutemann 23 Jan '23

23 Jan '23

'Phoronix compares the performance of Firefox and Chrome on the Linux desktop. They used recent releases (at default settings) for both browsers on an Intel Core i9 13900K "Raptor Lake" system with Radeon RX 6700XT graphics, concluding "out-of-the-box Google Chrome continues performing much better overall than Mozilla Firefox." One area where Firefox does better out-of-the-box is around the HTML5 Canvas such as measured via the CanvasMark test case. For the demanding JetStream 2 benchmark as one of the most demanding browser tests currently, Chrome on Linux was 67% faster than Firefox on this same Intel Raptor Lake desktop. Firefox did have a small win in the rather basic JavaScript Maze solver benchmark. Firefox at least was in a competitive space for the WebAssembly (WASM) benchmarks, but aside from that Google Chrome continues holding strong on Linux in the performance department.' -- source: https://news.slashdot.org/story/23/01/22/1922212 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

How Amazon Scammers Get Good Product Reviews
by Lawrence D'Oliveiro 18 Jan '23

18 Jan '23

In this report on a fake <https://arstechnica.com/gadgets/2023/01/64gb-microsd-cards-are-posing-as-16…> 16TB SSD that only turned out to be 64GB, there is a description of how the seller was able to accumulate quite a bunch of effusive reviews: the listing would originally have been for an entirely different, legitimate product. Then once a good number of positive comments had been built up, it would have been switched for the scam. The switch might happen multiple times, for legitimate products each time, to keep adding to the positivity, until the final con. However, this does mean that you end up with an accumulation of rather odd reviews: However, reading some of these reviews made me question if we've been using SSDs wrong all this time. A review on one of the remarkably cheap portable SSD listings declared the product to be "a very colorful throw, but thinner" than expected. Another reported that the drive proved "very soft and perfect" for their 6-year-old. One review pointed to the SSD being a "beautiful portrait" that looks great in the kitchen, while another five-star review pointed to the high microphone and video quality.

Vulnerability with 9.8 severity in Control Web Panel is under active exploit
by Peter Reutemann 16 Jan '23

16 Jan '23

'Malicious hackers have begun exploiting a critical vulnerability in unpatched versions of the Control Web Panel, a widely used interface for web hosting. “This is an unauthenticated RCE,” members of the Shadowserver group wrote on Twitter, using the abbreviation for remote code exploit. “Exploitation is trivial and a PoC published.” PoC refers to a proof-of-concept code that exploits the vulnerability. The vulnerability is tracked as CVE-2022-44877. It was discovered by Numan Türle of Gais Cyber Security and patched in October in version 0.9.8.1147. Advisories didn’t go public until earlier this month, however, making it likely some users still aren’t aware of the threat. Figures provided by Security firm GreyNoise show that attacks began on January 7 and have slowly ticked up since then, with the most recent round continuing through Wednesday. The company said the exploits are coming from four separate IP addresses located in the US, Netherlands, and Thailand. Shadowserver shows that there are roughly 38,000 IP addresses running Control Web Panel, with the highest concentration in Europe, followed by North America and Asia. The severity rating for CVE-2022-44877 is 9.8 out of a possible 10. “Bash commands can be run because double quotes are used to log incorrect entries to the system,” the advisory for the vulnerability stated. As a result, unauthenticated hackers can execute malicious commands during the login process. The following video demonstrates the flow of the exploit.' -- source: https://arstechnica.com/information-technology/2023/01/vulnerability-with-9… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Preparing To Disable Drivers For Microsoft's RNDIS Protocol
by Peter Reutemann 16 Jan '23

16 Jan '23

'Phoronix reports: With the next Linux kernel cycle we could see upstream disable their driver support for Microsoft's Remote Network Driver Interface Specification (RNDIS) protocol due to security concerns. RNDIS is the proprietary protocol used atop USB for virtual Ethernet functionality. The support for RNDIS outside of Microsoft Windows has been mixed. RNDIS isn't widely used today in cross-platform environments and due to security concerns the upstream Linux kernel is looking to move the RNDIS kernel drivers behind the "BROKEN" Kconfig option so they effectively become disabled in future kernel builds. Ultimately once marked as "BROKEN" for a while, the drivers will likely be eventually removed from the upstream source tree. Greg Kroah-Hartman wrote in a commit: "The Microsoft RNDIS protocol is, as designed, insecure and vulnerable on any system that uses it with untrusted hosts or devices. Because the protocol is impossible to make secure, just disable all rndis drivers to prevent anyone from using them again."' -- source: https://linux.slashdot.org/story/23/01/15/0220203 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Native Americans Ask Apache Foundation To Change Name
by Peter Reutemann 12 Jan '23

12 Jan '23

'Natives in Tech, a US-based non-profit organization, has called upon the Apache Software Foundation (ASF) to change its name, out of respect for indigenous American peoples and to live up to its own code of conduct. The Register reports: In a blog post, Natives in Tech members Adam Recvlohe, Holly Grimm, and Desiree Kane have accused the ASF of appropriating Indigenous culture for branding purposes. Citing ASF founding member Brian Behlendorf's description in the documentary "Trillions and Trillions Served" of how he wanted something more romantic than a tech term like "spider" and came up with "Apache" after seeing a documentary about Geronimo, the group said: "This frankly outdated spaghetti-Western 'romantic' presentation of a living and vibrant community as dead and gone in order to build a technology company 'for the greater good' is as ignorant as it is offensive." And the aggrieved trio challenged the ASF to make good on its code of conduct commitment to "be careful in the words that [they] choose" by choosing a new name. The group took issue with what they said was the suggestion that the Apache tribe exists only in a past historical context, citing eight federally recognized Native American tribes that bear the name. In a statement emailed to The Register, an ASF spokesperson said, "We hear the concerns from the Native American people and are listening. As a non-profit run by volunteers, changes will need time to be carefully weighed with members, the board, and our legal team. Our members are exploring alternative ways to address it, but we don't have anything to share at this time."' -- source: https://apache.slashdot.org/story/23/01/11/2159256 Changing all the URLs, library names etc (and how that affects everyone downstream) sounds like a massive undertaking...

'If you purchased a new car in the past few years, chances are good that it contains at least one embedded modem, which it uses to offer some connected services. The benefits, we've been told, are numerous and include convenience features like interior preheating on a cold morning, diagnostics that warn of failures before they happen, and safety features like teen driver monitoring. In some regions, connected cars are even mandatory, as in the European Union's eCall system. But if these systems sound like a potential security nightmare, that's because they often are. Ars has been covering car hacks for more than a decade now, but the problem really cemented itself in the public consciousness in 2015 with the infamous Jeep hacking incident, when a pair of researchers proved they could remotely disable a Jeep Cherokee while it was being driven, via an exploit in the SUV's infotainment system. Since then, security flaws have been found in some cars' Wi-Fi networks, NFC keys and Bluetooth, and in third-party telematics systems. Toward the end of 2022, a researcher named Sam Curry tested the security of various automakers and telematics systems and discovered security holes and vulnerabilities seemingly wherever he looked. Curry decided to explore the potential holes in the auto industry's digital infrastructure when he was visiting the University of Maryland last fall after playing around with an electric scooter's app and discovering that he could turn on the horns and headlights across the entire fleet. After reporting the vulnerability to the scooter company, Curry and his colleagues turned their attention to larger vehicles. [...] The researchers found extensive problems with 16 OEMs, telematics services like LoJack, new digital license plates, and even Sirius XM radio.' -- source: https://arstechnica.com/cars/2023/01/hackers-discover-that-vulnerabilities-… -- blog: https://samcurry.net/web-hackers-vs-the-auto-industry/ Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Messenger billed as better than Signal is riddled with vulnerabilities
by Peter Reutemann 11 Jan '23

11 Jan '23

'Academic researchers have discovered serious vulnerabilities in the core of Threema, an instant messenger that its Switzerland-based developer says provides a level of security and privacy “no other chat service” can offer. Despite the unusually strong claims and two independent security audits Threema has received, the researchers said the flaws completely undermine assurances of confidentiality and authentication that are the cornerstone of any program sold as providing end-to-end encryption, typically abbreviated as E2EE. Threema has more than 10 million users, which include the Swiss government, the Swiss army, German Chancellor Olaf Scholz, and other politicians in that country. Threema developers advertise it as a more secure alternative to Meta’s WhatsApp messenger. It’s among the top Android apps for a fee-based category in Switzerland, Germany, Austria, Canada, and Australia. The app uses a custom-designed encryption protocol in contravention of established cryptographic norms. Researchers from the Zurich-based ETH research university reported on Monday that they found seven vulnerabilities in Threema that seriously call into question the true level of security the app has offered over the years. Two of the vulnerabilities require no special access to a Threema server or app to cryptographically impersonate a user. Three vulnerabilities require an attacker to gain access to a Threema server. The remaining two can be exploited when an attacker gains access to an unlocked phone, such as at a border crossing.' -- source: https://arstechnica.com/information-technology/2023/01/messenger-billed-as-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

The Fairphone 2 Will Hit End-of-Life After 7 Years of Updates
by Peter Reutemann 11 Jan '23

11 Jan '23

'Ars Technica: It can be done. Android manufacturers can actually support a phone for a sizable amount of time. Fairphone has announced the end of life for the Fairphone 2, which will be March 2023. That phone was released in October 2015, so that's almost seven-and-a-half years of updates. Fairphone is a very small Dutch company with nowhere near as many resources as Google, Samsung, BBK, and the other Big-Tech juggernauts, yet it managed to outlast them with its support program. The whole goal of the company is sustainability, with easily repairable phones, available spare parts, and long update promises. The Fairphone 4 has a five-year hardware warranty and six years of updates, and the company's reputation says it can provide that. Sadly, the phones only ship in the UK and Europe. The Fairphone 2 only promised "three to five years" of updates, and it blew that out of the water. The Fairphone 2 features the Qualcomm Snapdragon 801 SoC, a chip that Qualcomm ended support for with Android 6.0. In what is probably an Android ecosystem first, that lack of chipset support didn't stop Fairphone, which teamed up with LineageOS and today ships Android 10 on the 7-year-old device. That's not the newest OS in the world, but it passes all of Google's Android compatibility tests. I'm sure there are newer amateur releases in the Android ROM community, but Fairphone's Android 10 build is up to the standard of an official release, as opposed to the "tell me what doesn't work" standard of many amateur ROM releases. Fairphone doesn't say why support is ending in March, but if it's staying on Android 10, it was going to have to kill support sometime this year. Google only supports security patches for the last four versions of Android, so even Google will be shutting down Android 10 support soon.' -- source: https://mobile.slashdot.org/story/23/01/10/2148222 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

ChatGPT is enabling script kiddies to write functional malware
by Peter Reutemann 10 Jan '23

10 Jan '23

'Since its beta launch in November, AI chatbot ChatGPT has been used for a wide range of tasks, including writing poetry, technical papers, novels, and essays and planning parties and learning about new topics. Now we can add malware development and the pursuit of other types of cybercrime to the list. Researchers at security firm Check Point Research reported Friday that within a few weeks of ChatGPT going live, participants in cybercrime forums—some with little or no coding experience—were using it to write software and emails that could be used for espionage, ransomware, malicious spam, and other malicious tasks. “It’s still too early to decide whether or not ChatGPT capabilities will become the new favorite tool for participants in the Dark Web,” company researchers wrote. “However, the cybercriminal community has already shown significant interest and are jumping into this latest trend to generate malicious code.” Last month, one forum participant posted what they claimed was the first script they had written and credited the AI chatbot with providing a “nice [helping] hand to finish the script with a nice scope.” The Python code combined various cryptographic functions, including code signing, encryption, and decryption. One part of the script generated a key using elliptic curve cryptography and the curve ed25519 for signing files. Another part used a hard-coded password to encrypt system files using the Blowfish and Twofish algorithms. A third used RSA keys and digital signatures, message signing, and the blake2 hash function to compare various files. The result was a script that could be used to (1) decrypt a single file and append a message authentication code (MAC) to the end of the file and (2) encrypt a hardcoded path and decrypt a list of files that it receives as an argument. Not bad for someone with limited technical skill.' -- source: https://arstechnica.com/information-technology/2023/01/chatgpt-is-enabling-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

New Linux Malware Downloader for Compromised Servers Spotted in the Wild
by Peter Reutemann 10 Jan '23

10 Jan '23

'"A new Linux malware downloader created using SHC (Shell Script Compiler) has been spotted in the wild," reports the site Bleeping Computer, "infecting systems with Monero cryptocurrency miners and DDoS IRC bots... "The analysts say the attacks likely rely on brute-forcing weak administrator account credentials over SSH on Linux servers.... " According to ASEC researchers, who discovered the attack, the SHC loader was uploaded to VirusTotal by Korean users, with attacks generally focused on Linux systems in the same country.... When the SHC malware downloader is executed, it will fetch multiple other malware payloads and install them on the device. One of the payloads is an XMRig miner that is downloaded as a TAR archive from a remote URL and extracted to "/usr/local/games/" and executed.... The second payload retrieved, dropped, and loaded by the SHC malware downloader is a Perl-based DDoS IRC bot. The malware connects to the designated IRC server using configuration data and goes through a username-based verification process. If successful, the malware awaits commands from the IRC server, including DDoS-related actions such as TCP Flood, UDP Flood, and HTTP Flood, port scanning, Nmap scanning, sendmail commands, process killing, log cleaning, and more. ASEC warns that attacks like these are typically caused by using weak passwords on exposed Linux servers.

Raspberry Pi Launches Higher Resolution Camera Module, Now With Autofocus
by Peter Reutemann 10 Jan '23

10 Jan '23

'Raspberry Pi is launching a new camera module for use with its diminutive DIY computers -- the Camera Module 3. Its upgraded Sony IMX708 sensor is higher resolution, but perhaps more important is that the new module supports high dynamic range photography and autofocus. Alongside it, Raspberry Pi is also releasing a new camera board for use with M12-mount lenses. From a report: Combined, the new features mean the Camera Module 3 should be able to take more detailed photographs (especially in low light), and can focus on objects as little as 5cm away. The autofocus uses a Phase Detection Autofocus (PDAF) system, with Contrast Detection Autofocus used as a backup. In contrast, previous versions of the camera module had fixed-focus lenses, which Raspberry Pi CEO Eben Upton writes were "optimized to focus at infinity" and could only take a "reasonably sharp image" of objects around a meter away. The new module's sensor has a resolution of 11.9 megapixels (compared to 8.1 megapixels for the last version), and has a higher horizontal resolution that should allow it to film HD video. HDR support means the Camera Module 3 can take several exposures of the same scene, and combine them so that both darker and lighter parts of an image are properly exposed (at the expense of some resolution) -- a trick commonly performed by just about every smartphone. Prices start at $25 for the Camera Module 3 with a standard field-of-view, while the ultra-wide angle version with a 102-degree field of view is $35.' -- source: https://tech.slashdot.org/story/23/01/09/1647247 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google wants RISC-V to be a “tier-1” Android architecture
by Peter Reutemann 04 Jan '23

04 Jan '23

'Over the holiday break, the footage from the recent "RISC-V Summit" was posted for the world to see, and would you believe that Google showed up to profess its love for the up-and-coming CPU architecture? We've been trying to nail down how the Android team feels about RISC-V (reduced instruction set computer) for a while. We last heard a comment from the team six months ago, where our Google I/O question about RISC-V was answered only with "we're watching, but it would be a big change for us." Some external RISC-V porting projects exist, and various RISC-V commits have been landing in the Android Open Source Project (AOSP), but since anyone can submit code to AOSP, it has been hard to make any bold proclamations about RISC-V's Android status. Google's keynote at the RISC-V Summit was all about bold proclamations, though. Lars Bergstrom, Android's director of engineering, wants RISC-V to be seen as a "tier-1 platform" in Android, which would put it on par with Arm. That's a big change from just six months ago. Bergstrom says getting optimized Android builds on RISC-V will take "a lot of work" and outlined a roadmap that will take "a few years" to come to fruition, but AOSP started to land official RISC-V patches back in September. The build system is up and running, and anyone can grab the latest "riscv64" branch whenever they want—and yes, in line with its recent Arm work, Google wants RISC-V on Android to be 64-bit only. For now, the most you can get is a command line, and Bergstrom's slide promised "initial emulator support by the start of 2023, with Android RunTime (ART) support for Java workloads following during Q1."' -- source: https://arstechnica.com/gadgets/2023/01/google-announces-official-android-s… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

X11 Server Development Pace Hits a Two Decade Low
by Peter Reutemann 04 Jan '23

04 Jan '23

'Michael Larabel writes via Phoronix: While Mesa's development has been very vibrant this year, the X.Org Server development pace has continued pulling back greatly from its late 00's and early 10's highs. This year saw just 156 commits to the xserver Git master branch, down from 331 last year and well off the highs of 2,114 as the most ever back in 2008. This jives with the downward pace over the past decade of the number of new commits continuing to slide. But it's not just on a commit basis but in overall code churn, 2022 was another low for the X.Org Server. With the 156 commits this year, there were just 3,618 lines of new code added and 888 lines removed.... Compared to last year with its 331 commits seeing 31.4k new lines and 179k lines removed. The X.Org Server development this year on a commit basis hasn't been as low since 2003 when there were just 125 commits under their old development model and even back then meant there was +865k lines /680k lines removed across that span of commits. There hasn't been so little code churn to the X Server since 2002. [...] This year saw commits from just 32 different email addresses, down from 48 in prior years and that number of different authors hasn't been so low since 2003 when there were just 10 recorded. Olivier Fourdan of Red Hat was the most prolific committer to the X.Org Server this year with nearly a quarter of the commits. Following Olivier was Jeremy Huddleston Sequoia, Peter Hutterer, Michel DÃnzer, Alan Coopersmith, and Sultan Alsawaf.

HandBrake video transcoder adds official AV1 codec support in latest release
by Peter Reutemann 03 Jan '23

03 Jan '23

'Hardware and software support for the royalty-free AV1 video codec has been steadily building over the last couple years. Hardware-accelerated encoding and decoding is becoming standard in more GPUs, phone SoCs, and other hardware, while streaming video services like YouTube and Netflix have begun serving AV1-encoded video to devices that support it. Open-source software projects are beginning to follow suit, too. The Open Broadcaster Software (OBS) package has been expanding its AV1 capabilities in recent releases, and now the HandBrake video transcoding app has added AV1 support as well. Version 1.6.0, released yesterday, has added support for encoding AV1 video using both CPU-based SVT-AV1 software encoding as well as via Intel's AV1-capable QuickSync video encoder included in its Arc GPUs.' -- source: https://arstechnica.com/gadgets/2022/12/handbrake-video-transcoder-adds-off… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Ellen Ullman: “The Dumbing Down Of Programming”
by Lawrence D'Oliveiro 24 Dec '22

24 Dec '22

Found this two-part article from Salon magazine of 1998 <https://www.salon.com/1998/05/12/feature_321/>, <https://www.salon.com/1998/05/13/feature_320/>. Choice quotes: My intention had been to buy an upgrade to Windows NT Server, which was a completely sensible thing for me to be doing. ... But somehow I left the store carrying a box of Linux from a company called Slackware. ... In six clicks of a wizard, the Microsoft C++ AppWizard steps me through the creation of an application skeleton. ... Of course, I could look at the code that the Wizard has generated. ... But everything in the environment urges me not to. ... In this programming world, the writing of my code has moved away from being the central task to become a set of appendages to the entire Microsoft system structure. I'm a scrivener here, a filler-in of forms, a setter of properties. ... I once worked on a project in which a software product originally written for UNIX was being redesigned and implemented on Windows NT. Most of the programming team consisted of programmers who had great facility with Windows, Microsoft Visual C++ and the Foundation Classes. In no time at all, it seemed, they had generated many screenfuls of windows and toolbars and dialogs, all with connections to networks and data sources, thousands and thousands of lines of code. But when the inevitable difficulties of debugging came, they seemed at sea. In the face of the usual weird and unexplainable outcomes, they stood a bit agog. It was left to the UNIX-trained programmers to fix things. ... In an ideal world, I would not have to choose between the extreme polarities of dialog box and source code. My dream system interface would allow me to start hesitantly, unschooled. Then, as I used the facility that distinguishes me from the machine -- the still-mysterious capacity to learn, the ability to do something the second time in a way quite different from the first -- I could descend a level to a smarter, quicker kind of "talk." I would want the interface to scale with me, to follow me as my interest deepened or waned.

Visual Effects Society 2021 Studio Platform Report
by Lawrence D'Oliveiro 23 Dec '22

23 Dec '22

Came across this interesting survey report <https://drive.google.com/file/d/15b-4GMTSEE9tyqeQdBfy_LZnxQIdp38Y/view> (Google Drive link to a downloadable PDF file), linked from this opinion piece <https://arstechnica.com/gadgets/2022/12/it-might-be-time-for-apple-to-throw…>. The report was released early this year from the Visual Effects Society Technology Committee, and looks at how companies working in the VFX industry are using different computing platforms. Interesting fact: three-fifths of the workstations at these companies run Linux, and this share looks to increase in the future. There is a mix of distros, but the largest share are running CentOS. This seems to be dictated by the vendors of the proprietary apps, who will only support certain distros and not others. And of course this leads to worries like where do they go after the end of CentOS. By the way, the “VFX Reference Platform” is a set of baseline technical specs which gets updated every year <https://vfxplatform.com/>, hence designations like “CY2021”. Some interesting comments are recorded in the report: Windows continues to be seen as “working out of the box”, yet the comments describe many ongoing headaches with managing Windows systems, including technical limitations like “character limits, limitations of Active Directory management”. Sometimes it looks like the users can be part of the problem: All our artists refuse to work with Linux and we chose to keep on Windows for their comfort. But sometimes it's hard to manage. (Not a peep about the famous brand loyalty of Mac users?) Seems like there is a definite long-term preference for greater Linux adoption, with pleas like Support for Enterprise Software (Video and Chat Platforms) on Linux. Support for realtime tech (NVIDIA, Epic) on Linux. and We could have only Linux if it was not for Adobe After Effects and a couple of other Adobe Creative Cloud Apps.

Microsoft discovers Windows/Linux botnet used in DDoS attacks
by Peter Reutemann 16 Dec '22

16 Dec '22

'Microsoft researchers have discovered a hybrid Windows-Linux botnet that uses a highly efficient technique to take down Minecraft servers and performs distributed denial-of-service attacks on other platforms. Dubbed MCCrash, the botnet infects Windows machines and devices running various distributions of Linux for use in DDoS attacks. Among the commands the botnet software accepts is one called ATTACK_MCCRASH. This command populates the user name in a Minecraft server login page with ${env:random payload of specific size:-a}. The string exhausts the resources of the server and makes it crash. “The usage of the env variable triggers the use of Log4j 2 library, which causes abnormal consumption of system resources (not related to Log4Shell vulnerability), demonstrating a specific and highly efficient DDoS method,” Microsoft researchers wrote. “A wide range of Minecraft server versions can be affected.”' -- source: https://arstechnica.com/information-technology/2022/12/microsoft-discovers-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

You Can Hook Your MIDI Keyboard Up To a Website With Firefox 108
by Peter Reutemann 15 Dec '22

15 Dec '22

'A new feature in Firefox version 108 that may please musicians is the improved support for the Web MIDI API. "The MIDI standard is very close to a remarkable 40 years old, and Web MIDI does just what the name implies: it allows web apps to send and receive MIDI signals to and from musical instruments," reports The Register. "In principle this will allow sequencer apps to be implemented in Javascript." From the report: Amusingly, the last time The Reg mentioned Web MIDI, it was because Apple was taking it off Safari users, allegedly because of security concerns. Firefox 108 addresses that with a new security mechanism for preventing, and optionally permitting, apps inside browser tabs to access hardware resources -- in this instance, your MIDI ports. No, this does not mean that you can listen to CANYON.MID directly within Firefox. .MID files are not the same as General MIDI. But if you are nostalgic for that for some reason, help is at hand.

Today, Edge, however pathetic, still outranks Firefox. Were FF not arguably the best available browser for Linux, share would be even less.

'The Z-Wave Alliance, the Standards Development Organization (SDO) dedicated to advancing the smart home and Z-Wave technology, today announced the completion of the Z-Wave Source Code project, which has been published and made available on GitHub to Alliance members. From a report: The Z-Wave Source Code Project opens development of Z-Wave and enables members to contribute code to shape the future of the protocol under the supervision of the new OS Work Group (OSWG). The goal of the project is to provide a rich development environment that contains the relevant source code and sample applications to those seeking to play a direct role in the advancement of the Z-Wave standard. The quality and interoperability of products utilizing Z-Wave Source Code will also be enforced by a new mandatory Silicon & Stack Certification program. Full Z-Wave certification will continue to test and certify for Z-Wave S2 security, network connectivity, range, battery life, and interoperability including backwards and forwards compatibility. "The Z-Wave Alliance is deeply committed to the global smart home market," said Mitch Klein, Executive Director of the Z-Wave Alliance. "This year the smart home conversations have focused largely on Matter. Shiny and new, and with big brands supporting the initiative, Matter is bringing a lot of attention to the smart home. This makes it easy to overlook Z-Wave as the most established, trusted, and secure smart home protocol, that also happens to have the largest certified interoperable ecosystem in the market.

Windows Driver-Signing Doesn’t Work
by Lawrence D'Oliveiro 14 Dec '22

14 Dec '22

Having Microsoft verify third-party drivers with a digital signature, so that Windows will block the loading of unsigned drivers, seemed like a good idea when it came in with Windows Vista. Enforcing quality control would remove a big source of crashes, as well as security loopholes. But it seems the execution falls somewhat short <https://arstechnica.com/information-technology/2022/10/no-fix-in-sight-for-…>. The system for revoking signatures for old, obsolete drivers that are discovered to have security vulnerabilities in them doesn’t seem to work very well, allowing miscreants to exploit this old code to gain control of Windows systems. This has been dubbed a “Bring Your Own Vulnerable Device/Driver” (BYOVD) attack. Microsoft’s own Vice President of “OS Security and Enterprise” continues to claim that “Windows has everything you need to block” buggy signed drivers. Yet the article’s author was unable to get the mechanism to work. And Microsoft itself appeared to have no interest in helping to fix that. It seems to me, one thing missing from the mechanism is a time limit on signature validity. By contrast, when you get SSL/TLS certs for your website, they are only valid for some fixed interval (e.g. a year for certs from traditional certificate authorities, 90 days for ones from Let’s Encrypt). This means that clients using such certificates do not need to maintain an ever-growing list of revoked ones to check against, since ones that are past their expiry date can be rejected anyway. If the cert for a Windows driver has expired, but the driver itself is still valid, Microsoft should be able to simply renew the certificate. But I guess if Microsoft’s servers are struggling just to distribute certificate revocations, having to push out renewals as well will likely just make things worse.

Xnspy Stalkerware Spied on Thousands of iPhones and Android Devices
by Peter Reutemann 13 Dec '22

13 Dec '22

'A little-known phone monitoring app called Xnspy has stolen data from tens of thousands of iPhones and Android devices, the majority whose owners are unaware that their data has been compromised. From a report: Xnspy is one of many so-called stalkerware apps sold under the guise of allowing a parent to monitor their child's activities, but are explicitly marketed for spying on a spouse or domestic partner's devices without their permission. Its website boasts, "to catch a cheating spouse, you need Xnspy on your side," and, "Xnspy makes reporting and data extraction simple for you." Stalkerware apps, also known as spouseware, are surreptitiously planted by someone with physical access to a person's phone, bypassing the on-device security protections, and are designed to stay hidden from home screens, which makes them difficult to detect.

Raspberry Pi Inventory Improving, Could Reach Pre-Pandemic Levels In 2023
by Peter Reutemann 13 Dec '22

13 Dec '22

'According to CEO Eben Upton, "hundreds of thousands" of Raspberry Pi Zero, 3A+, and 4 models should show up next year. Ars Technica reports: In a "Supply chain update" blog post ("It's good news!"), CEO Eben Upton wrote that Raspberry Pi has "set aside a little over a hundred thousand units, split across Zero W, 3A+, and the 2GB and 4GB variants of Raspberry Pi 4, for single-unit sales." During the pandemic-spurred component shortage, most of the Pis produced every month were going to businesses, leaving those in need of one or two for a project refreshing rpilocator and cursing their timing. Zeros will start showing up first, then 3A+, then different models of 4. Upton acknowledged this reality (and even linked the locator) and asked that people buy only from approved resellers and consider the Pico and Pico W lines for projects that might fit, as those lines remain strong. As of this morning, a few 3A+ and CM4 models showed an optimistic green on the rpilocator spreadsheet. Raspberry Pi will continue to serve its commercial and industrial customers, Upton wrote, but will "make sure that inventory-building behavior which would otherwise prolong the shortage for everybody else can't take place." Meanwhile, Raspberry Pi will increase the percentage of boards designated for single-unit sales. With that change and future chip allocations, Upton expects that by the end of the third quarter of 2023, things will be back to how they were before the Great Pi Shortage, with "hundreds of thousands of units available at any given time."

OSnews Decries 'The Mass Extinction of Unix Workstations'
by Peter Reutemann 12 Dec '22

12 Dec '22

'Anyone remember the high-end commercial UNIX workstations from a few decades ago — like from companies like IBM, DEC, SGI, and Sun Microsystems? Today OSnews looked back — but also explored what happens when you try to buy one today> : As x86 became ever more powerful and versatile, and with the rise of Linux as a capable UNIX replacement and the adoption of the NT-based versions of Windows, the days of the UNIX workstations were numbered. A few years into the new millennium, virtually all traditional UNIX vendors had ended production of their workstations and in some cases even their associated architectures, with a lacklustre collective effort to move over to Intel's Itanium — which didn't exactly go anywhere and is now nothing more than a sour footnote in computing history. Approaching roughly 2010, all the UNIX workstations had disappeared.... and by now, they're all pretty much dead (save for Solaris). Users and industries moved on to x86 on the hardware side, and Linux, Windows, and in some cases, Mac OS X on the software side.... Over the past few years, I have come to learn that If you want to get into buying, using, and learning from UNIX workstations today, you'll run into various problems which can roughly be filed into three main categories: hardware availability, operating system availability, and third party software availability. Their article details their own attempts to buy one over the years, ultimately concluding the experience "left me bitter and frustrated that so much knowledge — in the form of documentation, software, tutorials, drivers, and so on — is disappearing before our very eyes." Shortsightedness and disinterest in their own heritage by corporations, big and small, is destroying entire swaths of software, and as more years pass by, it will get ever harder to get any of these things back up and running.... As for all the third-party software — well, I'm afraid it's too late for that already. Chasing down the rightsholders is already an incredibly difficult task, and even if you do find them, they are probably not interested in helping you, and even if by some miracle they are, they most likely no longer even have the ability to generate the required licenses or release versions with the licensing ripped out. Stuff like Pro/ENGINEER and SoftWindows for UNIX are most likely gone forever.... Software is dying off at an alarming rate, and I fear there's no turning the tide of this mass extinction. The article also wonders why companies like HPE don't just "dump some ISO files" onto an FTP server, along with patch depots and documentation. "This stuff has no commercial value, they're not losing any sales, and it will barely affect their bottom line.' -- source: https://tech.slashdot.org/story/22/12/12/0116206 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Kernel Fixes Longstanding Bug in Its Handling of Floppy Disks
by Peter Reutemann 12 Dec '22

12 Dec '22

'"Linux kernel 6.2 should contain fixes for some problems handling floppy disks," reports the Register, "a move which shows that someone somewhere is still using them." This isn't the only such fix in recent years. As a series of articles on Phoronix details, there has been a slow but steady flow of fixes for the kernel's handling of floppy drives since at least kernel 5.17, as The Register mentioned when it came out.... Back in July 2016, SUSE kernel developer Jiri Kosina submitted a patch. The problem arose because this change broke something else and later got reverted, and so the problem hung around. In July last year, he sent in a new patch that fixed it again for the 5.12 kernel, and was later back-ported to 5.10, an LTS version, and again into kernel 5.15 — another an LTS version, and the one you're running today if you're on the current Ubuntu LTS release, or something built from it such as Linux Mint 21.... Now, in December 2022, a new patch for the forthcoming kernel 6.2 fixes a memory leak that dates back to 5.11 or before.' -- source: https://linux.slashdot.org/story/22/12/11/0711207 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google Reports Decline In Android Memory Safety Vulnerabilities As Rust Usage Grows
by Peter Reutemann 10 Dec '22

10 Dec '22

'Last year, Google announced Android Open Source Project (AOSP) support for Rust, and today the company provided an update, while highlighting the decline in memory safety vulnerabilities. 9to5Google reports: Google says the "number of memory safety vulnerabilities have dropped considerably over the past few years/releases."; Specifically, the number of annual memory safety vulnerabilities fell from 223 to 85 between 2019 and 2022. They are now 35% of Android's total vulnerabilities versus 76% four years ago. In fact, "2022 is the first year where memory safety vulnerabilities do not represent a majority of Android's vulnerabilities." That count is for "vulnerabilities reported in the Android security bulletin, which includes critical/high severity vulnerabilities reported through our vulnerability rewards program (VRP) and vulnerabilities reported internally." During that period, the amount of new memory-unsafe code entering Android has decreased: "Android 13 is the first Android release where a majority of new code added to the release is in a memory safe language. " Rust makes up 21% of all new native code in Android 13, including the Ultra-wideband (UWB) stack, DNS-over-HTTP3, Keystore2, Android's Virtualization framework (AVF), and "various other components and their open source dependencies." Google considers it significant that there have been "zero memory safety vulnerabilities discovered in Android's Rust code" so far across Android 12 and 13. Google's blog post today also talks about non-memory-safety vulnerabilities, and its future plans: "... We're implementing userspace HALs in Rust. We're adding support for Rust in Trusted Applications. We've migrated VM firmware in the Android Virtualization Framework to Rust. With support for Rust landing in Linux 6.1 we're excited to bring memory-safety to the kernel, starting with kernel drivers.' -- source: https://tech.slashdot.org/story/22/12/01/2124259 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Amazon Joins Open Invention Network
by Peter Reutemann 08 Dec '22

08 Dec '22

'Amazon and Amazon Web Services (AWS) have joined the Open Invention Network (OIN) -- the world's largest patent non-aggression consortium. ZDNet reports: OIN has long protected Linux and Linux-related software from patent aggression by rival companies. With the recent increase in patent troll attacks, the OIN is also defending companies from these assaults. This is a natural move for Amazon. Besides relying on Linux and open-source software both for its retail and cloud businesses, Amazon has a strict policy against patent infringement, and users who engage in this behavior can have their listings removed or accounts deleted. Nevertheless, like all large companies, Amazon has also been sued for patent violations. Joining the OIN simply makes good business sense. Nithya Ruff, the Amazon Open Source Program Office director, added: "Linux and open source are essential to many of our customers and a key driver of innovation across Amazon. We are proud to support a broad range of open-source projects, foundations, and partners, and we are committed to the long-term success and sustainability of open source as a whole. By joining OIN, we are continuing to strengthen open source communities and helping to ensure technologies like Linux remain thriving and accessible to everyone."' -- source: https://news.slashdot.org/story/22/12/07/2224237 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Four-Person Dev Team Gets Apple's M-Series GPU Working On Linux
by Peter Reutemann 08 Dec '22

08 Dec '22

'Ars Technica: For the brave people running Linux on Apple Silicon, their patience has paid off. GPU drivers that provide desktop hardware acceleration are now available in Asahi Linux, unleashing more of the M-series chips' power. It has taken roughly two years to reach this alpha-stage OpenGL driver, but the foundational groundwork should result in faster progress ahead, writes project leads Alyssa Rosenzweig and Asahi Lina. In the meantime, the drivers are "good enough to run a smooth desktop experience and some games." The drivers offer non-conformance-tested OpenGL 2.1 and OpenGL ES 2.0 support for all M-series Apple devices. That's enough for desktop environments and older games running at 60 frames per second at 4K. But the next target is Vulkan support. OpenGL work is being done "with Vulkan in mind," Lina writes, but some OpenGL support was needed to get desktops working first. There's a lot more you can read about the interplay between OpenGL, Vulkan, and Zink in Asahi's blog post.' -- source: https://tech.slashdot.org/story/22/12/07/2138241 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Syntax Errors Are the Doom of Us All, Including Botnet Authors
by Peter Reutemann 07 Dec '22

07 Dec '22

'KmsdBot, a cryptomining botnet that could also be used for denial-of-service (DDOS) attacks, broke into systems through weak secure shell credentials. It could remotely control a system, it was hard to reverse-engineer, didn't stay persistent, and could target multiple architectures. KmsdBot was a complex malware with no easy fix. That was the case until researchers at Akamai Security Research witnessed a novel solution: forgetting to put a space between an IP address and a port in a command. And it came from whoever was controlling the botnet. With no error-checking built in, sending KmsdBot a malformed command -- like its controllers did one day while Akamai was watching -- created a panic crash with an "index out of range" error. Because there's no persistence, the bot stays down, and malicious agents would need to reinfect a machine and rebuild the bot's functions. It is, as Akamai notes, "a nice story" and "a strong example of the fickle nature of technology." KmsdBot is an intriguing modern malware. It's written in Golang, partly because Golang is difficult to reverse-engineer. When Akamai's honeypot caught the malware, it defaulted to targeting a company that created private Grand Theft Auto Online servers. It has a cryptomining ability, though it was latent while the DDOS activity was running. At times, it wanted to attack other security companies or luxury car brands.' -- source: https://it.slashdot.org/story/22/12/06/1552228 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Company 'Hijacks' Blender's CC BY-Licensed Film, YouTube Strikes User
by Peter Reutemann 06 Dec '22

06 Dec '22

'TorrentFreak: The Blender Institute develops Blender, a free and open source 3D graphics tool used to create animated films. Sintel and Big Buck Bunny are among Blender's most recognizable titles and due to Creative Commons licensing (CC BY), they are widely shared, used, remixed and reshared. According to original Blender creator Ton Roosendaal, "Open licenses are essential for sharing our films and their source material." Right now, a company is claiming that Blender's free content is actually their content and as a result, must be immediately removed from the internet. We're talking about content that was created with Blender's explicit blessing but even after multiple appeals, not even YouTube will see reason. Bruno Fernandez-Ruiz is the co-founder and CTO at AI-focused driver safety company, Nexar. On Sunday he informed TorrentFreak that he's also an independent film composer and producer, working with music production libraries, and distributing to the main music platforms. TorrentFreak contacted Bruno after noticing a post he made on a music production forum. He wrote that after uploading a video containing a clip from the Blender movie Caminandes 3 -- Llamigos, YouTube notified him that a rightsholder had filed a copyright complaint, his video had been taken down, and a copyright strike had been issued to his account. The complaint, sent by Uzbekistan-based media/news company ZO'R TV, was not the result of automatic matching under Content ID. It was filed as a formal DMCA notice, meaning that someone probably reviewed the details before sending the complaint. The notice claimed that Bruno had infringed ZO'R TV's copyrights by reproducing content (6:21 to 8:26) from this YouTube video published in 2018. Since the content in question is obviously from Blender's film Caminandes 3, ZO'R TV was in no position to issue a DMCA notice. On that basis, Bruno followed the recognized procedure by sending a DMCA counternotice to YouTube. It didn't go well. After filing his counternotice with YouTube, Bruno was informed that since he'd provided insufficient information, YouTube could not process it. However, YouTube did inform Bruno of the risks of filing a counternotice, including that his name could be sent to the claimant, ZO'R TV in this case. Determined to have his video restored, Bruno accepted the risks and sent another counternotice to YouTube. This time there was no indication that the counternotice was deficient. YouTube thanked him for filing it -- but still declined to process it. YouTube's email advised Bruno that counternotices should only be filed in case of a mistake or misidentification. Consulting with a lawyer first might be helpful, YouTube added. After three attempts to restore the video and have the copyright strike removed, YouTube responded once again. The message contained yet more disappointment for Bruno. "Based on the information that you have provided, it appears that you do not have the necessary rights to post the content on YouTube. Therefore, we regretfully cannot honor your request," it advised. This signaled the end of the debate as far as YouTube was concerned and by rejecting Bruno's right to send a counternotice, the platform denied him an opportunity to have the video restored, stand up for Blender's rights, and get the strike removed. After notifying Blender of the situation, Blender developed Ton Roosendaal replied, saying the company has "no staff here available to go after situations like this" but suggested they could "escalate it to the Creative Commons organization." "After all, it's their mission," he added.' -- source: https://news.slashdot.org/story/22/12/05/2212216 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Mint 20.2: Mate / GTK issue?
by Peter Reutemann 05 Dec '22

05 Dec '22

Hi everyone Just in case some one else encounters this problem... Last Friday, I installed the latest kernel update on my Linux Mint 20.2 MATE edition and rebooted the first time in a few weeks. After logging back in, I noticed that the Xorg process was using almost one core on my laptop. This wasn't the case when waiting at the login prompt (i.e., lightdm). Starting my file browser of choice, GTK version of double-command, (package: doublecmd-gtk), seemed to grab another core. Downgrading of Xorg or using an older kernel had no impact, unfortunately. When switching to XFCE4 for my session today, I didn't experience that high CPU load problem anymore. I also switched to the QT version of double-commander (package: doublecmd-qt). Not really solving the problem, more like side-stepping it, but at least I get can work done again, without my laptop fan going hard out all day... And I've used XFCE in the past. :-) Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Today’s New Word: “Cyberdeck”
by Lawrence D'Oliveiro 04 Dec '22

04 Dec '22

What is a “cyberdeck”? According to <https://hackaday.com/tag/cyberdeck/>, it’s basically a style of home-built computer with futuristic/sci-fi/cyberpunk overtones. The name comes from (what else) a William Gibson novel. It seems common to use a Raspberry π as the beating heart, with a custom 3D-printed case around it plus other suitably interesting-looking parts. Angles seem preferable to curves, with asymmetrically-inset polygons very popular. Weird and wacky keyboard layouts are a bonus. The diminutive size of the Raspberry π leaves plenty of room for experimentation. We can build the future-that-never-was! We have the technology now.

Web Browsers Drop Mysterious Company With Ties To US Military Contractor
by Peter Reutemann 02 Dec '22

02 Dec '22

'Washington Post: Major web browsers moved Wednesday to stop using a mysterious software company that certified websites were secure, three weeks after The Washington Post reported its connections to a U.S. military contractor. Mozilla's Firefox and Microsoft's Edge said they would stop trusting new certificates from TrustCor Systems that vouched for the legitimacy of sites reached by their users, capping weeks of online arguments among their technology experts, outside researchers and TrustCor, which said it had no ongoing ties of concern. Other tech companies are expected to follow suit. The Post reported on Nov. 8 that TrustCor's Panamanian registration records showed the same slate of officers, agents and partners as a spyware-maker identified this year as an affiliate of Arizona-based Packet Forensics, which has sold communication interception services to U.S. government agencies for more than a decade. One of those contracts listed the "place of performance" as Fort Meade, Md., the home of the National Security Agency and the Pentagon's Cyber Command. The case has put a new spotlight on the obscure systems of trust and checks that allow people to rely on the internet for most purposes. Browsers typically have more than a hundred authorities approved by default, including government-owned ones and small companies, to seamlessly attest that secure websites are what they purport to be. "Certificate Authorities have highly trusted roles in the internet ecosystem and it is unacceptable for a CA to be closely tied, through ownership and operation, to a company engaged in the distribution of malware," Mozilla's Kathleen Wilson wrote to a mailing list for browser security experts. "Trustcor's responses via their Vice President of CA operations further substantiates the factual basis for Mozilla's concerns."' -- source: https://tech.slashdot.org/story/22/12/01/2113209 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mozilla Acquires Team Behind Pulse, an Automated Status Updater for Slack
by Peter Reutemann 02 Dec '22

02 Dec '22

'Firefox developer Mozilla is making a rare foray into the world of mergers and acquisitions, with news that it has snapped up recently-shuttered California-based productivity startup Pulse. From a report: Terms of the deal haven't been disclosed, but the deal is tantamount to an "acqui-hire," with Mozilla looking to deploy the Pulse team across an array of machine learning (ML) projects. "We're acquiring Pulse for the incredible team they have built," Mozilla chief product officer Steve Teixeira told TechCrunch. "As we look to continue to improve user experiences across all of our products, ML will be a core part of that." Founded out of Menlo Park in 2019, Pulse in its initial guise was a "virtual office" platform called Loop Team, but after honing the idea for a couple of years it pivoted and rebranded last November. Pulse, essentially, was an automated status-updating tool that used signals based on pre-configured integrations and preferences set by the user. For example, users could synchronize Pulse with their calendar and Slack, setting rules to stipulate what their status and corresponding emoji should be based on keywords in their calendar event title. If their schedule for a particular time says "hair appointment" from 12-1pm, then the person's Slack status update might display a scissors emoji alongside the word "haircut." Or, it might say "birthday" alongside a cake emoji if that's what is in their calendar.' -- source: https://tech.slashdot.org/story/22/12/01/1644245 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Used thin client PCs are an unsexy, readily available Raspberry Pi alternative
by Peter Reutemann 30 Nov '22

30 Nov '22

'"Raspberry Pi boards are hard to get, probably also next year," says Andreas Spiess, single-board enthusiast and YouTuber, in his distinctive Swiss accent. He's not wrong. Spiess says he and his fellow Pi devotees need "a strategy to survive" without new boards, so he suggests looking in one of the least captivating, most overlooked areas of computing: used, corporate-minded thin client PCs. Spiess' Pi replacements, suggested and refined by many of his YouTube commenters and Patreon subscribers, are Fujitsu Futros, Lenovo ThinkCentres, and other small systems (some or all of which could be semantically considered "thick clients" or simply "mini PCs," depending on your tastes and retro-grouch sensibilities). They're the kind of systems you can easily find used on eBay, refurbished on Amazon Renewed, or through other enterprise and IT asset disposition sources. They're typically in good shape, given their use and environment. And compared to single-board enthusiast systems, many more are being made and replaced each year.' -- source: https://arstechnica.com/gadgets/2022/11/used-thin-client-pcs-are-an-unsexy-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Anker's Eufy Cameras Caught Uploading Content To the Cloud Without User Consent
by Peter Reutemann 30 Nov '22

30 Nov '22

'Anker's popular Eufy-branded security cameras appear to be sending some data to the cloud, even when cloud storage is disabled and local only storage settings are turned on. MacRumors reports: The information comes from security consultant Paul Moore, who last week published a video outlining the issue. According to Moore, he purchased a Eufy Doorbell Dual, which was meant to be a device that stored video recording on device. He found that Eufy is uploading thumbnail images of faces and user information to its cloud service when cloud functionality is not enabled. Moore demonstrates the unauthorized cloud uploading by allowing his camera to capture his image and turning off the Eufy HomeBase. The website is still able to access the content through cloud integration, though he had not signed up for cloud service, and it remains accessible even when the footage is removed from the Eufy app. It's important to note that Eufy does not appear to be automatically uploading full streaming video to the cloud, but rather taking captures of the video as thumbnails. The thumbnails are used in the Eufy app to activate streaming video from the Eufy base station, allowing Eufy users to watch their videos when away from home, as well as for sending rich notifications. The problem is the thumbnails are uploaded to the cloud automatically even when the cloud functionality is not active, and Eufy also seems to be using facial recognition on the uploads. Some users have taken issue with the unauthorized cloud uploads because Eufy advertises local-only service and has been popular among those who want a more private camera solution. "No Clouds or Costs," reads the Eufy website. Moore suggests that Eufy is also able to link facial recognition data collected from two separate cameras and two separate apps to users, all without camera owners being aware. Moore received a response from Eufy in which Eufy confirmed that it is uploading event lists and thumbnails to AWS, but said the data is not able to "leak to the public" because the URL is restricted, time limited, and requires account login. There is also another issue that Moore has highlighted, suggesting Eufy camera streams can be watched live using an app like VLC, but little information on the exploit is available at this time. Moore said that unencrypted Eufy camera content can be accessed without authentication, which is alarming for Eufy users. There's a dedicated Reddit thread where other Eufy users are reporting the same thing happening.' -- source: https://yro.slashdot.org/story/22/11/29/2148250 Eufy products are for sale here in NZ as well.

Amazon's New Chip Moves AWS Into High-Performance Computing
by Peter Reutemann 30 Nov '22

30 Nov '22

'Amazon's cloud-computing unit is rolling out new chips designed to power the highest-end of computing, supporting tasks such as weather forecasting and gene sequencing. From a report: Amazon Web Services, the largest provider of over-the-internet computing, on Monday said it would let customers rent computing power that relies on a new version of its Graviton chips. Peter DeSantis, a senior vice president who oversees most of AWS's engineering teams, said in an interview that the product is a springboard for making what the industry calls high-performance computing more readily available. The newest chip is the latest piece of Amazon's effort to build more of the hardware that fills the massive data centers that power AWS. Amazon says making its own chips will give customers more cost-effective computing power than they could get by renting time on processors built by the likes of Intel Corp., Nvidia Corp. or Advanced Micro Devices. The move has put AWS in direct competition with those companies, which are also among its biggest suppliers. DeSantis said the chipmakers remain "great partners," and that AWS plans to continue to offer high-performance computing services based on chips made by other companies. On Tuesday, AWS Chief Executive Officer Adam Selipsky announced a new version of the Inferentia chip, which is designed to draw inferences from vast amounts of data. Inferentia2 is built to handle bigger sets of data than its predecessor, enabling things like software-generated images or detecting and interpreting human speech, Amazon said. [...] The latest version of AWS's line of Graviton processors, the Graviton3E, will have twice the ability of current versions in one type of calculations needed by high-performance computers, DeSantis said. When combined with other AWS technology, the new offering will be 20% better than the previous one. Amazon didn't say when services based on the new chip would be available' -- source: https://tech.slashdot.org/story/22/11/29/192229 According to this site, the Graviton2 chip is supported by several Linux distros (specific kernel flags?): https://aws.amazon.com/ec2/graviton/ Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

RIP Fred “Mythical Man-Month” Brooks
by Lawrence D'Oliveiro 29 Nov '22

29 Nov '22

“The Mythical Man-Month” was a classic book on the nature of computer programming, written by Fred Brooks after (among other things) his experience heading up the OS/360 project back in the 1960s. The man himself has now passed away at the age of 91 <https://www.theregister.com/2022/11/28/fred_mythical_man_month_brooks/>. OS/360 was the most ambitious of several operating systems developed by IBM for its System/360 line of computers. It provided conclusive proof that, if a project was running late, adding more people to work on it could actually make things worse. I have a copy of the 25th-Anniversary edition of the book, which includes his “No Silver Bullet” essay and also a detailed retrospective on how the original text stood up (or not) to the state of the programming art in the 1990s.

Linux Kernel Gets More Infrastructure for Rust, Increasing Interest in the Language
by Peter Reutemann 28 Nov '22

28 Nov '22

'Linux 6.1 (released last month) included what Linus Torvalds described as "initial Rust scaffolding," remembers this update from SD Times But now, "work has already been done since the 6.1 release to add more infrastructure for Rust in the kernel, though still none of the code interacts with any C code." And there's still no actual Rust code in Linux: "You need to get all those things that can make sure that Rust can compile, and you can do the debugging and all these things," explained Joel Marcey, director of advocacy and operations for the Rust Foundation, "and make sure that the memory safety is there and all that sort of stuff. And that has to happen first before you can actually write any real code in Rust for the Linux kernel itself." Marcey explained that Linux is going to be doing this inclusion very piecemeal, with lots of little integrations here and there over time so they can see how it is working. "I would imagine that over the next year, you're going to see more small incremental changes to the kernel with Rust, but as people are seeing that it's actually kind of working out, you'll be able to maybe, for example, write Linux drivers or whatever with Rust," said Marcey.... According to Bec Rumbul, executive director of the Rust Foundation, Rust being added to the kernel is an "enormous vote of confidence in the Rust programming language." She explained that in the past other languages have been planned to make it into the kernel and ended up not getting put in. "I think having someone with the kind of intellectual gravity of Linus Torvalds saying 'No, it's going in there,' that kind of says an awful lot about how reliable Rust already is and how much potential there is for the future as well," she said. Rumbul believes that there will be an increased interest in the language, which is still relatively new (It first made its debut in 2010) compared to some of the other languages out there to choose from. "I suspect that because Rust is now in the kernel, and it's just being talked about much ... more widely, that it will seem like an attractive prospect to a lot of people that are looking to develop their skills and their knowledge," she said. Rumbul hopes people will also be inspired to participate in the language as contributors and maintainers, because those are some of the less popular roles within open source, but are extremely critical to the health of a language, she explained. The Rust Foundation also launched a new security team in September to ensure best practices (including a dedicated security engineer). Their first initiative will be a security audit and threat modeling exercises. "We want to basically shore up," Rust operations director Marcey tells SD Times, "to ensure that Rust itself is actually as secure as we always say it is." In this year's Stack Overflow Developer Survey, 86.73% of developers said they love Rust.' -- source: https://developers.slashdot.org/story/22/11/27/1853228 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google Says Google and Other Android Manufacturers Haven't Patched Security Flaws
by Peter Reutemann 25 Nov '22

25 Nov '22

'Google has disclosed several security flaws for phones that have Mali GPUs, such as those with Exynos chipsets. From a report: The company's Project Zero team says it flagged the problems to ARM (which produces the GPUs) back in the summer. ARM resolved the issues on its end in July and August. However, smartphone manufacturers including Samsung, Xiaomi, Oppo and Google itself hadn't deployed patches to fix the vulnerabilities as of earlier this week, Project Zero said. Researchers identified five new issues in June and July and promptly flagged them to ARM. "One of these issues led to kernel memory corruption, one led to physical memory addresses being disclosed to userspace and the remaining three led to a physical page use-after-free condition," Project Zero's Ian Beer wrote in a blog post. "These would enable an attacker to continue to read and write physical pages after they had been returned to the system." Beer noted that it would be possible for a hacker to gain full access to a system as they'd be able to bypass the permissions model on Android and gain "broad access" to a user's data. The attacker could do so by forcing the kernel to reuse the afore-mentioned physical pages as page tables.' -- source: https://tech.slashdot.org/story/22/11/24/218212 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

DSA Slowly Going Away
by Lawrence D'Oliveiro 24 Nov '22

24 Nov '22

I notice that the new version of OpenSSH in Debian Unstable is taking another step toward dropping support for the DSA algorithm for key generation. I can remember back when DSA was introduced as an alternative to RSA. Unlike RSA, which is an encryption algorithm that can also be used for digital signatures, DSA was deliberately designed to be usable for signatures but not for encryption. This was back in the day when the US Government was still restricting exports of strong encryption products. Not long after that, I remember a research paper being published showing that DSA could in fact be used as an encryption algorithm. It wasn’t particularly efficient or even very practical, but it could theoretically be done. There was a time, in fact, when DSA was actually being preferred to RSA for generating SSH keys. Just checking the ssh-keygen man page, and the current default is RSA.

Windows Subsystem for Linux with GUI apps launches for Windows 10
by Peter Reutemann 24 Nov '22

24 Nov '22

'The Windows Subsystem for Linux (WSL), one of the best reasons to run Windows 11, is now available to Windows 10 users, in the latest version and with all its features. WSL dropped its "preview" label with this 1.0 release, and aims to simplify its installation from here on out. Getting the best version of WSL used to mean installing big, system-level Windows updates (including 11 itself). As part of its broader moving of key apps into its Store, Microsoft now offers the most feature-rich version of WSL there. "The in-Windows version of WSL will still receive critical bug fixes, but the Store version of WSL is where new features and functionality will be added," Windows Developer Platform Program Manager Craig Loewen noted in a blog post. Loewen noted that the "WSL community's requests" drove Microsoft to make the latest, GUI-ready framework version available to Windows 10 users. Now a Store installation is the default, even if you use the command line (PowerShell) to install and update WSL. Now anyone whose system is capable of running WSL has access to graphical apps and (optional) systemd support, and can hopefully spend less time wondering which WSL version they have, what they need, and what the differences are.' -- source: https://arstechnica.com/gadgets/2022/11/windows-subsystem-for-linux-with-gu… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Network-crashing leap seconds to be abandoned by 2035, for at least a century
by Peter Reutemann 23 Nov '22

23 Nov '22

'There are not many things you can get Facebook, Google, the United States, France, and Linus Torvalds to agree on, but one of them has come to pass. A near-unanimous vote on Friday in Versailles, France, by parties to the International Bureau of Weights and Measures (BIPM in its native French) on Resolution 4 means that starting in 2035, the leap second, the remarkably complicated way of aligning the Earth's inconsistent rotation with atomic-precision timekeeping, will see its use discontinued. Coordinated Universal Time, or UTC, will run without them until 2135. It was unclear whether any leap seconds might occur before then, though it seems unlikely. The assumption is that within those 100 years, time-focused scientists (metrologists) will have found a way to synchronize time as measured by humans to time as experienced by our planet orbiting the Sun. But most people will not notice any difference at all, even as the time difference could reach up to one minute by the end of that 100 years.' -- source: https://arstechnica.com/science/2022/11/network-crashing-leap-seconds-to-be… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Tumblr To Add Support For ActivityPub, the Social Protocol Powering Mastodon and Other Apps
by Peter Reutemann 22 Nov '22

22 Nov '22

'TechCrunch: Tumblr will add support for ActivityPub, the open, decentralized social networking protocol that's today powering social networking software like Twitter alternative Mastodon, the Instagram-like Pixelfed, video streaming service PeerTube, and others. The news was revealed in a response to a Twitter user's complaint about Mastodon's complexities. Automattic CEO Matt Mullenweg -- whose company acquired Tumblr from Verizon in 2019 -- suggested the user "come to Tumblr" as the site would soon "add activitypub for interconnect." "Don't stress," he said, before clarifying that Tumblr first has to deal with the waves of new users coming in right now from Twitter, but that support for "interop and activitypub" were due to come "ASAP." In short, this announcement means Tumblr would move from being only a niche blogging platform to instead become a part of a larger, decentralized social network of sorts -- and one whose user base has grown in size in recent days as people flee Elon Musk's Twitter in search of new communities. The ActivityPub protocol, its website explains, provides a client-to-server API for creating, updating, and deleting content as well as a federal server-to-server API for delivering notifications and subscribing to content. In practice, this means that Mastodon users can interact and follow users on other instances (independently run nodes), as well as with users on other social apps (like PeerTube), which also support the implementation of ActivityPub. It makes for a web of social networks where users can find and follow each other without having to set up new accounts on each new service. This is the opposite approach to today's "walled garden" social networks, where a post on one platform can't be viewed by those on others, unless you re-upload or repost the content directly or share a link to the other site where the content can be found.' -- source: https://tech.slashdot.org/story/22/11/21/2320217 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

A History Of ARM, Part 2
by Lawrence D'Oliveiro 22 Nov '22

22 Nov '22

Quite a nice article <https://arstechnica.com/gadgets/2022/11/a-history-of-arm-part-2-everything-…> covering the founding of ARM Ltd as parent company Acorn was hitting financial headwinds. Apple played an absolutely crucial part in keeping the company viable in its early days by being among its biggest customers: the Newton PDA sold 60,000 units in its first year, which was a flop for Apple but, at $20 a unit for royalties, a big boost for ARM Ltd at the time. In those early days, the company found it an uphill struggle to be taken seriously by the bigger players. Companies like Motorola and TI had trouble appreciating why they could not create their own in-house designs instead of licensing one from ARM, even when the latter could be done for a fraction of the cost of the former. But the boss was canny and persistent enough to make the right sort of deals to build a sound basis for the company: For Robin Saxby, the idea of working with rival chip companies was always part of the strategy. “Turn your enemies into friends,” he would say. “Why should they fight you if they can make more money for themselves by collaborating with you?” Unfortunately, big companies don’t always act rationally ...

AMD Finally Opens Up Its Radeon Raytracing Analyzer 'RRA' Source Code
by Peter Reutemann 22 Nov '22

22 Nov '22

'Michael Larabel, reporting for Phoronix: This summer AMD announced the Radeon Raytracing Analyzer "RRA" as part of their developer software suite for helping to profile ray-tracing performance/issues on Windows and Linux with both Direct3D 12 and the Vulkan API. Initially the RRA 1.0 release was binary-only but now AMD has made good on their "GPUOpen" approach and made it open-source. As noted back in my original article from July on the Radeon Raytracing Analyzer release: "Radeon Raytracing Analyzer is hosted on GitHub but the only content in the actual Git repository right now is documentation, so it would appear that at least initially this is a closed-source package though some documentation also says it's MIT licensed." Last week that was cleared up with the Radeon Raytracing Analyzer source code going public. There are build instructions for compiling the RRA 1.0 sources on both Microsoft Windows and Linux while the Linux instructions are tailoring to Ubuntu use. Building the Radeon Raytracing Analyzer depends upon the Qt 5.15 toolkit.' -- source: https://news.slashdot.org/story/22/11/21/1716219 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

The Creator of Homebrew's Plan To Get Open Source Contributors Paid - Using Blockchain
by Peter Reutemann 21 Nov '22

21 Nov '22

'The creator of the Linux/macOS package manager Homebrew has a new package manager named Tea. But according to Stack Overflow's podcast, the software also "aims to solve the problem of providing funding for popular open source projects." While he is not a crypto bull, Max was inspired with a solution for the open source funding dilemma by his efforts to buy and sell an NFT. A contract written in code and shared in public enforced a rule sending a portion of his proceeds to the digital objects original creator. What if the same funding mechanism could be applied to open source projects?Â In March of 2022, Max and his co-founder launched Tea, a sort of spirtual successor to Homebrew. It has a lot of new features Max wanted in a package manager, plus a blockchain based approach to ensuring that creators, maintainers, and contributors of open source software can all get paid for their efforts. You can read Max's launch post on Tea here and yes, of course there is a white paper. The paper describes the proposed solution as "a decentralized system for fairly remunerating open-source developers based on their contributions to the entire ecosystem and enacted through the tea incentive algorithm applied across all entries in the tea registry." And the launch post calls tea "our revolution against a failing system," arguing "We're taking our knowledge of how to make development more efficient and throwing innovations nobody has ever really considered before. "Package managers haven't been sexy. Until now. Most importantly, we're moving the package registry on-chain (relax, we'll use a low-energy proof of stake chain). This has numerous benefits due to the inherent benefits of blockchain technology." For starters, decentralized storage will make the packages always-available and immutable, signed by maintainers themselves. But there's more: web3 has enabled novel new ways to distribute value, and with our system people who care about the health of the open source ecosystem buy some token and stake it. Periodically, we reward this staking because it is securing our token network. We give a portion of these rewards to the staker and a portion to packages of their choice along with all the dependencies of those packages. Note that no portion goes to us. We're not like the other app stores.... tea is the home to a DAO that will ensure the open source maintainers that keep the Internet running are rewarded as they deserve. An introduction to the white paper adds that in the spirit of the open source movement, "we're inviting developers, speculators, and enthusiasts alike to contribute to our white paper and help brew the future of the internet. This is our revolutionary undertaking to create equitable openâsource for web3, and we want you to be a part of laying its groundwork."' -- source: https://news.slashdot.org/story/22/11/19/2047223 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Can Mastodon Be A Twitter Alternative?
by Lawrence D'Oliveiro 18 Nov '22

18 Nov '22

This article <https://www.aljazeera.com/economy/2022/11/7/can-mastodon-be-a-twitter-alter…> says: With Twitter in disarray since the world’s richest person took control of it last week, Mastodon, a decentralised, open alternative from privacy-obsessed Germany, has seen a flood of new users. Nevertheless, this “flood” is a mere trickle compared to the torrent of users that is Twitter -- a million or so active monthly users on the one, versus over 200 times that on the other. The decentralization of Mastodon means that no single entity can take control of it. But it also makes it harder for users to find their way around. [Mastodon creator] Rochko, whose Mastodon foundation runs on a shoestring crowdfunded budget topped up with a modest grant from the European Commission, has found a particularly receptive audience among privacy-conscious European regulators. Germany’s data protection commissioner is waging a campaign to get government bodies to close their Facebook pages, since, he says, there is no way of hosting a page there that conforms to European privacy laws. Authorities should move to the federal government’s own Mastodon instance, he says. The European Commission also maintains a server for European Union bodies to toot from. Yeah ... “toot” ...

OpenPrinting Keeps Old Printers Working -- Even On Windows
by Lawrence D'Oliveiro 12 Nov '22

12 Nov '22

This report from the Ubuntu Summit <https://www.theregister.com/2022/11/10/openprinting_keeps_old_printers_work…> I think nicely highlights the inevitable consequences of Microsoft allowing Linux into Windows with WSL2. Linux has long had better support for older printers and other hardware than Windows. Even after the vendors of the products drop support for their Windows drivers, others have found ways to create and maintain open-source drivers for those products. Now, the circle is turning back, with these same open-source drivers being offered back to Windows users, by running them on the Linux subsystem under WSL2. I don’t think it’s a coincidence that this offering is coming from Ubuntu/Canonical, given their increasingly cosy relationship with Microsoft. Sure, if you want to talk “Embrace, Extend, Extinguish”, just note that the platform being “embraced” and “extended” is not Linux being extended with formerly Windows-only capabilities, but Windows being extended with formerly Linux-only capabilities. As Microsoft and other vendors increasingly realize that, instead of developing proprietary Windows-only drivers, it is much less work to encourage the creation of open-source ones for Linux, that Windows can also use in this way via WSL2, where do you think this is going to lead?

Lenovo Driver Goof Poses Security Risk for Users of 25 Notebook Models
by Peter Reutemann 11 Nov '22

11 Nov '22

'More than two dozen Lenovo notebook models are vulnerable to malicious hacks that disable the UEFI secure-boot process and then run unsigned UEFI apps or load bootloaders that permanently backdoor a device, researchers warned on Wednesday. From a report: At the same time that researchers from security firm ESET disclosed the vulnerabilities, the notebook maker released security updates for 25 models, including ThinkPads, Yoga Slims, and IdeaPads. Vulnerabilities that undermine the UEFI secure boot can be serious because they make it possible for attackers to install malicious firmware that survives multiple operating system reinstallations. Short for Unified Extensible Firmware Interface, UEFI is the software that bridges a computer's device firmware with its operating system. As the first piece of code to run when virtually any modern machine is turned on, it's the first link in the security chain. Because the UEFI resides in a flash chip on the motherboard, infections are difficult to detect and remove. Typical measures such as wiping the hard drive and reinstalling the OS have no meaningful impact because the UEFI infection will simply reinfect the computer afterward. ESET said the vulnerabilities -- tracked as CVE-2022-3430, CVE-2022-3431, and CVE-2022-3432 -- "allow disabling UEFI Secure Boot or restoring factory default Secure Boot databases (incl. dbx): all simply from an OS." Secure boot uses databases to allow and deny mechanisms. The DBX database, in particular, stores cryptographic hashes of denied keys. Disabling or restoring default values in the databases makes it possible for an attacker to remove restrictions that would normally be in place.' -- source: https://it.slashdot.org/story/22/11/10/1610252 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

SPARK: A Competitor To Rust?
by Lawrence D'Oliveiro 09 Nov '22

09 Nov '22

Here’s another contender for a modern language that is low-level yet emphasizes minimization of bugs, to compete with the likes of Rust: it’s called SPARK <https://devclass.com/2022/11/08/spark-as-good-as-rust-for-safer-coding-adac…>. It’s not a completely new language, since according to the report it is a subset of Ada. The original Ada language came about in the 1980s out of a competition organized by the US Department of Defense, to create a language specifically designed for programming embedded and safety-critical systems. The most high-profile application of it that I know of is that the life-support systems on the International Space Station are written in Ada, and run on ancient (but well-tested) Intel 386 processors. So I would say that’s a good pedigree to start from.

The Linux Kernel Has Been Forcing Different Behavior For Processes Starting With 'X'
by Peter Reutemann 09 Nov '22

09 Nov '22

'"An ugly hack within the Linux kernel that has been in mainline for over three years has been called out," writes Phoronix's Michael Larabel. "Due to a buggy X.Org Server / xf86-video-modesetting DDX, the Linux kernel has been imposing different behavior on whether a process starts with 'X' and in turn disable the atomic mode-setting support." Linux security researcher and WireGuard creator, Jason Donenfeld, discovered the 'ugly code' within the kernel and commented on it via the kernel mailing list. "The commit to this kernel with the 'X' first character check was made back in September 2019," notes Larabel. "The 'good' news is that since then on user-space side back in 2019 the xf86-video-modesetting code went ahead and disabled atomic support by default. So technically if running an updated X.Org stack within the past three years, this kernel hack isn't necessary anymore since user-space is just then avoiding the atomic API."' -- source: https://linux.slashdot.org/story/22/11/08/2211244 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

KDE: Stopping The Windows/Super Key From Popping Up The App Menu
by Lawrence D'Oliveiro 07 Nov '22

07 Nov '22

I thought I had this disabled before, but KDE Plasma has this feature where you just need to press and release the Super key (or “Windows” key, if your keyboard has the proprietary logo on it), and the application menu will appear. It seems there is no GUI setting to disable this, but you can turn it off according to this <https://superuser.com/questions/1156130/kde-disable-super-l-windows-key-key…>. First, make the described edit to your KWin config file, in ~/.config/kwinrc, which you can do conveniently with kwriteconfig5 --file kwinrc --group ModifierOnlyShortcuts --key Meta "" Then either log out your GUI session and log in again, or try just restarting your window manager with kwin_x11 --replace & in some convenient terminal window. The writeup above doesn’t mention putting the “&” on the end, so KWin remains attached to that terminal session, which means you can’t use it for anything else ...

Outlawing Dark Patterns
by Lawrence D'Oliveiro 05 Nov '22

05 Nov '22

“Dark patterns” is a term coined to describe user interfaces designed to manipulate people into giving up time, money or personal data that they didn’t intend to. A common example is the obstacle course you often have to go through to cancel a subscription to something online. Another example is the use of countdown timers to rush buyers into hasty decisions. They may not be out-and-out deceptive, but they do come close. Now, the US states of California and Washington are looking to pass laws to restrict this practice. <https://arstechnica.com/tech-policy/2021/01/lawmakers-take-aim-at-insidious…>

New Hampshire Set To Pilot Voting Machines That Use Open-Source Software
by Peter Reutemann 04 Nov '22

04 Nov '22

'According to The Record, New Hampshire will pilot a new kind of voting machine that will use open-source software to tally the votes. The Record reports: The software that runs voting machines is typically distributed in a kind of black box -- like a car with its hood sealed shut. Because the election industry in the U.S. is dominated by three companies -- Dominion, Election Systems & Software and Hart InterCivic -- the software that runs their machines is private. The companies consider it their intellectual property and that has given rise to a roster of unfounded conspiracy theories about elections and their fairness. New Hampshire's experiment with open-source software is meant to address exactly that. The software by its very design allows you to pop the hood, modify the code, make suggestions for how to make it better, and work with other people to make it run more smoothly. The thinking is, if voting machines run on software anyone can audit and run, it is less likely to give rise to allegations of vote rigging. The effort to make voting machines more transparent is the work of a group called VotingWorks. [...] On November 8, VotingWorks machines will be used in a real election in real time. New Hampshire is the second state to use the open-source machines after Mississippi first did so in 2019. Some 3,000 voters will run their paper ballots through the new machines, and then, to ensure nothing went awry, those same votes will be hand counted in a public session in Concord, N.H. Anyone who cares to will be able to see if the new machines recorded the votes correctly. The idea is to make clear there is nothing to hide. If someone is worried that a voting machine is programmed to flip a vote to their opponent, they can simply hire a computer expert to examine it and see, in real time.

The “ip” command, aka the “iproute2” suite, offers a huge amount of functionality for managing the Linux network stack. The initial man page, “man ip”, gives an overview, and (at least on my current system) ends with references to more: SEE ALSO ip-address(8), ip-addrlabel(8), ip-ioam(8), ip-l2tp(8), ip-link(8), ip-maddress(8), ip-monitor(8), ip-mptcp(8), ip-mroute(8), ip-neighbour(8), ip-netns(8), ip-ntable(8), ip-route(8), ip-rule(8), ip-stats(8) ip-tcp_metrics(8), ip-token(8), ip-tunnel(8), ip-vrf(8), ip-xfrm(8) IP Command reference ip-cref.ps That “ip-cref.ps” file doesn’t seem to be included in any Debian packages I can see. However, when I look in the /usr/share/man/man8 directory, I find a few more man pages not mentioned in the above list: ip-nexthop.8.gz ip-fou.8.gz ip-macsec.8.gz ip-gue.8.gz (symlink to ip-fou.8.gz) ip-netconf.8.gz ip-sr.8.gz That “ip fou”/“ip gue” command lets you tunnel arbitrary IP protocols over a pair of UDP ports.

The Godot Game Engine Now Has Its Own Foundation
by Peter Reutemann 04 Nov '22

'The Godot Engine now has its own foundation to continue funding themselves. Previously, they teamed up with the Software Freedom Conservancy to handle fiscal sponsorship duties. Phoronix reports: The Godot engine developers and Software Freedom Conservancy mutually agreed to move the open-source game engine project to its own foundation. The Godot Foundation has been setup in the Netherlands as its own organization modeled after the policies of the SFC. The Godot Foundation is to help this game engine achieve its next level of growth and project a stronger image for the project. "We have just started the process of moving to the Foundation," writes Godot Engine lead developer, Juan Linietsky, in a blog post. "For now all of Godot's funding and contractors are still managed by the SFC. The SFC will gradually reduce its work for Godot and the new foundation will slowly ramp up. Stay tuned for announcements in the future as we finalize the Foundation's organizational structure and officially begin operations."

Google Ad For GIMP.org Served Info-Stealing Malware Via Lookalike
by Peter Reutemann 03 Nov '22

03 Nov '22

'A report from BleepingComputer, written by Ax Sharma: Searching for 'GIMP' on Google as recently as last week would show visitors an ad for 'GIMP.org,' the official website of the well known graphics editor, GNU Image Manipulation Program. This ad would appear to be legitimate as it'd state 'GIMP.org' as the destination domain. But clicking on it drove visitors to a lookalike phishing website that provided them with a 700 MB executable disguised as GIMP which, in reality, was malware. Reddit user ZachIngram04 earlier shared the development stating that the ad previously took users to a Dropbox URL to serve malware, but was soon "replaced with an even more malicious one" which employed a fake replica website 'gilimp.org' to serve malware. BleepingCompuer observed another domain 'gimp.monster' related to this campaign. To pass off the trojanized executable as GIMP in a believable manner to the user, the threat actor artificially inflated the malware, that is otherwise under 5 MB in size, to 700 MB by a simple technique known as binary padding. It still isn't clear if this instance was a slip up caused by a potential bug in Google Ad Manager that allowed malvertising.' -- source: https://tech.slashdot.org/story/22/11/02/1944255 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mastodon Gained 70,000 Users After Musk's Twitter Takeover
by Peter Reutemann 03 Nov '22

03 Nov '22

'"More than 70,000 users joined Mastodon on the day after Musk's Twitter takeover announcement," writes Slashdot reader votsalo. "Mastodon is a six-year-old decentralized social media platform that uses 'federated' servers." The Guardian's Wilfred Chan writes: I joined Mastodon this week, and it took a few hours just to master its new vocabulary. Some of it is a little silly-sounding: instead of tweets, you have "toots". Things get trickier after that. Mastodon is not a single website but a network of thousands of websites called "instances", also called servers. These servers are "federated", which means they are run by different entities but can still communicate with each other without needing to go through a central system. And the space they all exist in is called the "fediverse," which some savvy tooters call "the Fedi." When you sign up for Mastodon, the first thing you do is choose a server. There are general-purpose ones, such as mastodon.social, as well as ones aimed at interest groups, such as kpop.social or linuxrocks.online. There are also joke servers like dolphin.town, where the only thing users are allowed to post is the letter "e". The server becomes part of your username (for example, wilfred(a)kpop.social), and the toots you see on your feed are toots from your server-mates, rather than from the entire fediverse. But you're also free to toot at people from other servers and even "boost" their public toots on to your feed. That's how Mastodon creates a unified global experience without being controlled by one entity, said Eugen Rochko, Mastodon's Germany-based founder and lead developer. "The servers are service providers, like Hotmail and Gmail are for email. It doesn't mean that the different servers are isolated from each other, like old school forums," he said. "Having just one account allows you to follow and interact with anyone in this global decentralized social network." But Mastodon's model comes with its own risks. If the server you join disappears, you could lose everything, just like if your email provider shut down. A Mastodon server admin also has ultimate control over everything you do: if for some reason the owner of kpop.social doesn't like that I boosted a toot from dolphin.town, they could remove it or even "defederate" the server, which would block all dolphin toots from the k-pop server completely. A server admin could also snoop on my private toots if they wanted to -- or delete my account for any reason. While Mastadon's 70,000 jump in users sounds impressive, it's "still a drop in a bucket compared with Twitter's reported 450 million daily active users," says Chan. The decentralized software also remains difficult for many people to use. According to TechCrunch, Mastadon says it has "gained 123,562 new users as of October 27, 2022 and now has 528,607 active users on the network as of October 31, 2022."' -- source: https://tech.slashdot.org/story/22/11/02/1958241 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Backblaze: Buying Cheaper, Less Reliable Drives Can Be Worth It
by Lawrence D'Oliveiro 02 Nov '22

02 Nov '22

Backup company Backblaze has put out another juicy status report on the reliability of its massive collection of hard drives <https://blocksandfiles.com/2022/11/01/backblaze-disk-drives/>. This one has some interesting numbers on the cost of dealing with drive failures -- it seems the hardware cost of these to the company is zero, as the failed drives get sent back to the vendors for full credit or replacement. (I guess if you buy a few thousand units at a time, you get special deals like this.) Since the company is in the business of providing sufficient redundancy that the impact of a drive failure on data integrity is essentially zero, the main cost of a failure becomes the labour cost of putting in a new drive, which comes to $300. Looked at this way, looking at the table which compares three models of drive, with unit costs ranging from $225 up to $275, and corresponding annualized failure rates of 1.5% down to 0.5%, it turns out the cheaper, flakier drive is the better deal -- amortized over a five-year service lifetime, the increased labour cost of replacing failed drives is easily outweighed by the savings in buying the drives in the first place.

OpenSSL 3 patch, once Heartbleed-level “critical,” arrives as a lesser “high”
by Peter Reutemann 02 Nov '22

02 Nov '22

'An OpenSSL vulnerability once signaled as the first critical-level patch since the Internet-reshaping Heartbleed bug has just been patched. It ultimately arrived as a "high" security fix for a buffer overflow, one that affects all OpenSSL 3.x installations, but is unlikely to lead to remote code execution. OpenSSL version 3.0.7 was announced last week as a critical security fix release. The specific vulnerabilities (now CVE-2022-37786 and CVE-2022-3602) had been largely unknown until today, but analysts and businesses in the web security field hinted there could be notable problems and maintenance pain. Some Linux distributions, including Fedora, held up releases until the patch was available. Distribution giant Akamai noted before the patch that half of their monitored networks had at least one machine with a vulnerable OpenSSL 3.x instance, and among those networks, between 0.2 and 33 percent of machines were vulnerable. But the specific vulnerabilities—limited-circumstance, client-side overflows that are mitigated by the stack layout on most modern platforms—are now patched, and rated as "High." And with OpenSSL 1.1.1 still in its long-term support phase, OpenSSL 3.x is not nearly as widespread.' -- source: https://arstechnica.com/information-technology/2022/11/openssl-3-patch-once… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

LineageOS flashing
by Peter Reutemann 01 Nov '22

01 Nov '22

Hi everyone Since I've talked about flashing LineageOS on Android phones before... In the past, I've always used TWRP (https://twrp.me/) as recovery tool on the phones. However, the tools has been lagging behind with Android 12 support and the 3.7.0 release (which in theory added Android 12 support) failed on my old Galaxy S7 (I'm using custom ROMs supplied by Ivan Meier). Unfortunately, OrangeFox Recovery, which seems a popular alternative to TWRP, didn't support my Galaxy S7. However, I found a little workaround for that dilemma: though I used TWRP to install Android 11, during the setup process I then ticked the box to also update the recovery tool with LineageOS recovery with the every subsequent update. After updating the phone to the latest Android 11, I had LineageOS recovery on there which has (working) support for Android 12 and I managed to upgrade successfully to 12. Just in case somebody runs into a similar problem...

'Old/Weird Laptops' Sought To Help Test Linux Kernel Backlight Drivers
by Peter Reutemann 28 Oct '22

28 Oct '22

'Do you have a laptop that's either "pretty old" or "weird in some other way"? Did it ship without Windows from the factory, or did you flash its firmware with coreboot? You could help the Linux kernel move its backlight code forward without abandoning quirky gear like yours. ArsTechnica: Hans de Goede, a longtime Linux developer and principal engineer at Red Hat, writes on his Livejournal about the need to test "a special group of laptops" to prevent their backlight controls from disappearing in Linux kernel 6.1. Old laptop tests are needed because de Goede is initiating some major changes to user-space backlight controls, something he has been working on since 2014. As detailed at Linux blog Phoronix, there are multiple issues with how Linux tries to address the wide variety of backlight schemes in displays, which de Goede laid out at the recent Linux Plumbers Conference. There can be multiple backlight devices operating a single display, leaving high-level controls to "guess which one will work." Brightness control requires root permissions at the moment. And "0" passed along as a backlight value remains a conundrum, as the engineer pointed out in 2014: Is that entirely off, or as low as the display can be lit?' -- source: https://linux.slashdot.org/story/22/10/27/1920206 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Passkeys Are Finally Here
by Peter Reutemann 26 Oct '22

26 Oct '22

'Ars Technica: Generically, passkeys refer to various schemes for storing authenticating information in hardware, a concept that has existed for more than a decade. What's different now is that Microsoft, Apple, Google, and a consortium of other companies have unified around a single passkey standard shepherded by the FIDO Alliance. Not only are passkeys easier for most people to use than passwords; they are also completely resistant to credential phishing, credential stuffing, and similar account takeover attacks. On Monday, PayPal said US-based users would soon have the option of logging in using FIDO-based passkeys, joining Kayak, eBay, Best Buy, CardPointers, and WordPress as online services that will offer the password alternative. In recent months, Microsoft, Apple, and Google have all updated their operating systems and apps to enable passkeys. Passkey support is still spotty. Passkeys stored on iOS or macOS will work on Windows, for instance, but the reverse isn't yet available. In the coming months, all of that should be ironed out, though. Passkeys work almost identically to the FIDO authenticators that allow us to use our phones, laptops, computers, and Yubico or Feitian security keys for multi-factor authentication. Just like the FIDO authenticators stored on these MFA devices, passkeys are invisible and integrate with Face ID, Windows Hello, or other biometric readers offered by device makers. There's no way to retrieve the cryptographic secrets stored in the authenticators short of physically dismantling the device or subjecting it to a jailbreak or rooting attack. Even if an adversary was able to extract the cryptographic secret, they still would have to supply the fingerprint, facial scan, or -- in the absence of biometric capabilities -- the PIN that's associated with the token. What's more, hardware tokens use FIDO's Cross-Device Authentication flow, or CTAP, which relies on Bluetooth Low Energy to verify the authenticating device is in close physical proximity to the device trying to log in. "Users no longer need to enroll each device for each service, which has long been the case for FIDO (and for any public key cryptography)," said Andrew Shikiar, FIDO's executive director and chief marketing officer. "By enabling the private key to be securely synced across an OS cloud, the user needs to only enroll once for a service, and then is essentially pre-enrolled for that service on all of their other devices. This brings better usability for the end-user and -- very significantly -- allows the service provider to start retiring passwords as a means of account recovery and re-enrollment." In other words: "Passkeys just trade WebAuthn cryptographic keys with the website directly," says Ars Review Editor Ron Amadeo. "There's no need for a human to tell a password manager to generate, store, and recall a secret -- that will all happen automatically, with way better secrets than what the old text box supported, and with uniqueness enforced." If you're eager to give passkeys a try, you can use this demo site created by security company Hanko.' -- source: https://yro.slashdot.org/story/22/10/25/1912214 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Memtest86+ Is Back After 9 Years
by Peter Reutemann 26 Oct '22

26 Oct '22

'Memtest86+ just got its first update after 9 years. The program has reportedly been rewritten from scratch and is back in active development. The new version, 6.0, features a plethora of updates to bring the application up to date, and support the latest system hardware from Intel and AMD. Tom's Hardware reports: For the uninitiated, MemTest86 was originally created back in the mid 1990s, and was one of the earliest DDR memory testing applications for personal computers. But development stopped in 2013 once Memtest86 was split into Memtest86 and Memtest86", with the former being bought by PassMark. Officially, we don't know why development stopped. But compared to the now modern Memtest86, Memtest86+ is the open-source variant. Needless to say, version 6.00 features a lot of updates, which were required to bring it up to modern standards compared to the 2013 version. The new version includes completely rewritten code for UEFI-based motherboards, the modern version of a BIOS, for both 32-bit and 64-bit versions of the application. Furthermore, the application features added support for x64 long mode paging, support for up to 256 cores, added detection for DDR4 and DDR5 memory -- since DDR3 was the latest memory standard in 2013 -- and adds support for XMP version 3.0. CPU support has been significantly enhanced, addingdetection for all pre-Zen and AMD Zen-based processors ranging from the Ryzen 1000 series to 7000 series, and any older parts that were made after 2013. Intel support has also been added for chips up to 13th gen Raptor Lake. Finally, the last patch notes indicate version 6.0 adds support for older Nvidia and AMD chipsets - probably pre-2010 since it mentions Nvidia nForce chipsets, along with numerous bug fixes, optimizations and enhancements.' -- source: https://hardware.slashdot.org/story/22/10/24/2315242 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Just When You Thought Y2K Was Done And Dusted ...
by Lawrence D'Oliveiro 25 Oct '22

25 Oct '22

Remember what the whole Y2K issue was like, over a quarter-century ago? And all the work that had to be done to fix it? You’d think that lessons were learned, software developers would be wiser, and henceforth they would always use four digits for year numbers, so that a situation like that would not occur again. Guess again. Recently I hit a situation where a piece of software was *still* using just two digits for year numbers. Basically it was maintaining Certificate Revocation Lists (CRLs) for OpenVPN connections; these have an expiry date, in the form of the “nextupdate” field, to ensure that outdated lists are regularly replaced with fresh ones, to reduce the chance that anybody is inadvertently continuing to use compromised keys. The software in question is pfSense, from Netgate <https://forum.netgate.com/topic/172870/crl-has-expired>. The standard format for these CRLs can handle a full range of dates, but the internal system on pfSense for generating them can only handle years from 1950 to 2049. The generated CRLs were being given validity durations of 9999 days, which was fine up until about August this year, when the expiry date went past 2049, and wrapped around to 1950. On an incoming connection attempt, OpenSSL would check the CRL, find it invalid, and cause OpenVPN to drop the connection. The forum discussion above links to a patch to fix the issue. Only the patch doesn’t really make for a permanent fix: all it does is reduce the assigned validity duration from 9999 days to 730 days; the actual underlying software is still only working with 2-digit year numbers. This gives Netgate a few decades’ breathing room to come up with a proper fix.

'Firefox 106 is now available for download, bringing various new features and enhancements, such as a new PDF editing feature and new way to organize recently closed tabs. 9to5Linux reports: Mozilla says that Firefox 106 finally brings the long-anticipated two-finger swipe horizontal gesture for navigating back and forward on a website without having to hold down the Alt key. [...] Firefox 106 also introduces annotation capabilities to the built-in PDF viewer so you can write text, draw, or add signatures on PDF files. You'll be able to change the size and color of the text tool, as well as the thickness, opacity, and color of the draw tool. Another interesting new feature of the Firefox 106 release is called Firefox View, which is implemented as a pinned tab, promising to help you get back to the content you've previously discovered by allowing you to switch seamlessly between your devices running Firefox.

In Praise of FFmpeg
by Peter Reutemann 19 Oct '22

19 Oct '22

'Drew DeVault, prolific FOSS blogger and hacker behind SourceHut, Sway, wlroots, and many other projects, writes in a blog post: I have relied on ffmpeg for many tasks and for many years. It has always been there to handle any little multimedia-related task I might put it to for personal use -- re-encoding audio files so they fit on my phone, taking clips from videos to share, muxing fonts into mkv files, capturing video from my webcam, live streaming hacking sessions on my own platform, or anything else I can imagine. It formed the foundation of MediaCrush back in the day, where we used it to optimize multimedia files for efficient viewing on the web, back when that was more difficult than "just transcode it to a webm." ffmpeg is notable for being one of the first large-scale FOSS projects to completely eradicate proprietary software in its niche. Virtually all multimedia-related companies rely on ffmpeg to do their heavy lifting. It took a complex problem and solved it, with free software. The book is now closed on multimedia: ffmpeg is the solution to almost all of your problems. And if it's not, you're more likely to patch ffmpeg than to develop something new. The code is accessible and the community are experts in your problem domain. ffmpeg is one of the foremost pillars of achievement in free software. It has touched the lives of every reader, whether they know it or not. If you've ever watched TV, or gone to a movie, or watched videos online, or listened to a podcast, odds are that ffmpeg was involved in making it possible. It is one of the most well-executed and important software projects of all time.' -- source: https://tech.slashdot.org/story/22/10/17/188205 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google Announces KataOS
by Peter Reutemann 19 Oct '22

19 Oct '22

'Last Friday, Google announced the release of KataOS, a security-minded operating system focused on embedded devices running ambient machine learning workloads. As Phoronix notes, it uses the Rust programming language and is "built atop the seL4 microkernel as its foundatin." From Google's Open-Source Blog: As the foundation for this new operating system, we chose seL4 as the microkernel because it puts security front and center; it is mathematically proven secure, with guaranteed confidentiality, integrity, and availability. Through the seL4 CAmkES framework, we're also able to provide statically-defined and analyzable system components. KataOS provides a verifiably-secure platform that protects the user's privacy because it is logically impossible for applications to breach the kernel's hardware security protections and the system components are verifiably secure. KataOS is also implemented almost entirely in Rust, which provides a strong starting point for software security, since it eliminates entire classes of bugs, such as off-by-one errors and buffer overflows. The current GitHub release includes most of the KataOS core pieces, including the frameworks we use for Rust (such as the sel4-sys crate, which provides seL4 syscall APIs), an alternate rootserver written in Rust (needed for dynamic system-wide memory management), and the kernel modifications to seL4 that can reclaim the memory used by the rootserver. KataOS code is being worked on via GitHub under the AmbiML umbrella.' -- source: https://tech.slashdot.org/story/22/10/17/2256206 Someone keen to demo this at one of our next meetings?

Linus Torvalds To Kernel Devs: Grow Up and Stop Pulling All-Nighters Just Before Deadline
by Peter Reutemann 19 Oct '22

19 Oct '22

'Linux kernel boss Linus Torvalds has released the first release candidate for version 6.1 of the project and added an appeal for developers to make his life easier by adding code earlier in the development cycle. The Register reports: "Let me just say that after I got my machine sorted out and caught up with the merge window, I was somewhat frustrated with various late pull requests. I've mentioned this before, but it's _really_ quite annoying to get quite a few pull requests in the last few days of the merge window." He then offered further guidance on how kernel devs can do it right. "Yes, the merge window is two weeks, but that's very much to allow me time to look things over, not 'two weeks to hurriedly put together a branch that you send Linus on Friday of the second week'," he wrote. "The whole 'do an all-nighter to get the paper in the day before the deadline' is something that should have gone out the window after high school. Not for kernel development." His next line was: "You know who you are." "Anyway, it's not the first time I've said this, I doubt it will be the last. But maybe more people could take it to heart, ok?" he added, before concluding his post with a slightly non-traditional call for testers to visit Linux's git tree because "The merge window may not be the biggest ever, but it's certainly big enough that the shortlog is much too big to post, and below is just my usual merge log." "For all the gory details, please refer to the git tree."' -- source: https://linux.slashdot.org/story/22/10/17/220230 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Ubuntu's New Terminal 'Ad' is Angering Users
by Peter Reutemann 19 Oct '22

19 Oct '22

'Joey Sneddon, reporting at OMG! Ubuntu: In September I tweeted a screenshot of something unexpected that has started to show up in the terminal when I ran system updates. It didn't enrage me at the time (and it kinda still doesn't) but I did find it a little ... Off. Now, if you're suitably tuned-in to the Linux newswire and/or an avid attendee of social media you'll probably heard about the drama in question. If you haven't, then allow me to... Yes, the furore is over an "ad" for Ubuntu Pro, Canonical's revamped support offering that replaces/augments Ubuntu Advantage (which has been around for many years) that appears in the terminal when managing system updates. Other people are calling it an "ad" (hence quote marks). I prefer the term plug (which, it turns out, some people aren't familiar with; it means to mention something in order to promote it). For although this sentence is technically advertising something, in this case Ubuntu Pro, the offering itself is free for regular users (on up-to five devices). Thus, it's not like this is an "ad" that generates Canonical revenue. It's more akin to a public service announcement to raise awareness.' -- source: https://news.slashdot.org/story/22/10/18/1847203 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Xv6 Open-Source Teaching OS
by Lawrence D'Oliveiro 17 Oct '22

17 Oct '22

You may know that the MINIX operating system, the inspiration for Linux, was created for teaching purposes (namely, Andrew Tanenbaum’s “Operating Systems” textbook). In the same vein, Xv6 is a newer teaching OS from MIT <https://pdos.csail.mit.edu/6.828/2022/xv6.html>, for use in an undergraduate operating systems course. Originally it was implemented on x86, but now it has moved to RISC-V. The inspiration for Xv6 was the old 6th Edition Unix from Bell Labs from 1975, back when it only ran on DEC PDP-11 processors. This OS version was the subject of the famous “Lions book” <https://en.wikipedia.org/wiki/A_Commentary_on_the_UNIX_Operating_System>, circulation of which was supposed to be restricted to those with licences to the Unix source code. And then with the 7th Edition, AT&T even forbade classroom use of this source code. Nevertheless, the book still spread via, shall we say, samizdat ... The Xv6 GitHub area is here <https://github.com/mit-pdos>.

Pine64 Announces 'Sub-$10, Linux-Capable' SBC - the Ox64
by Peter Reutemann 17 Oct '22

17 Oct '22

'Pine64 has announced a new "sub $10 Linux capable single board computer" called the Ox64. Liliputing says the tiny SBC "looks a lot like a Raspberry Pi Pico. But while Raspberry Pi's tiny board is powered by an RP2040 microcontroller, the Ox64 has a dual-core RISC-V processor, 64MB of embedded RAM, and support for up to 128Mb of flash storage plus a microSD card for additional storage." It's expected to support RTOS and Linux and blurs the lines between a microcontroller and a (very low power) single-board PC. It's expected to go on sale in November with prices starting at $6 for an RTOS-ready version of the board and $8 for a Linux-compatible model. As spotted by CNX Software earlier this month, the board is designed to be a small, inexpensive single-board computer with a RISC-V processor that's aimed at developers. Pine64's October update also reveals that their Star64 and QuartzPro64 single-board computers "now boot Linux (and run it well too already!)"' -- source: https://news.slashdot.org/story/22/10/15/2314226 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Bad DIMM on Linus Torvalds' Desktop System Moves Kernel Merges to His Laptop
by Peter Reutemann 17 Oct '22

17 Oct '22

'When a kernel developer asked Linus Torvalds if he'd missed a Git pull, Torvalds "revealed the request was still in his queue as 'I'm doing merges (very slowly) on my laptop, while waiting for new ECC memory DIMMs to arrive,'" reports The Register: Torvalds needs the DIMMs because over the last few days he experienced what he described as "some instability on my main desktop... with random memory corruption in user space resulting in my allmodconfig builds randomly failing with internal compiler errors etc." The Linux boss's first thought was that a new kernel bug had caused the problem — which isn't good but sometimes happens. His instinct was wrong. "It was literally a DIMM going bad in my machine randomly after 2.5 years of it being perfectly stable," he wrote. "Go figure. Verified first by booting an old kernel, and then with memtest86+ overnight." Torvalds appears to have been tracking delivery of the new DIMMs as he reported replacement memory was "out for delivery" and predicted it should arrive later on Sunday evening.... His post also mentions that his main PC was set up for error correction code memory (ECC memory), but "during the early days of COVID when there wasn't any ECC memory available at any sane prices. And then I never got around to fixing it, until I had to detect errors the hard way." "I absolutely *detest* the crazy industry politics and bad vendors that have made ECC memory so 'special'," he added.' -- source: https://linux.slashdot.org/story/22/10/15/2334251 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft Office Rebranding
by Lawrence D'Oliveiro 14 Oct '22

14 Oct '22

I suppose you’ve heard by now that “Microsoft Office” is losing the “Office” part of the name, and becoming “Microsoft 365”. Accompanying this rebranding is a new set of logos <https://arstechnica.com/gadgets/2022/10/rip-to-microsoft-office-henceforth-…>. One thing I notice about them is the gradient shading, shadows and general faux-3D look. Does this mark an end to the “flat” design fad that seems to have become so popular over the last decade? Or does this only apply to the logo branding, not to onscreen icons, UI etc? (In which case, I wonder how their design gurus feel about such a disconnect between those different aspects of the same product.) Of course, I ask this as someone who never stopped being a fan of 3D style ...

Android Leaks Some Traffic Even When 'Always-On VPN' Is Enabled
by Peter Reutemann 13 Oct '22

13 Oct '22

'Mullvad VPN has discovered that Android leaks traffic every time the device connects to a WiFi network, even if the "Block connections without VPN," or "Always-on VPN," features is enabled. BleepingComputer reports: The data being leaked outside VPN tunnels includes source IP addresses, DNS lookups, HTTPS traffic, and likely also NTP traffic. This behavior is built into the Android operating system and is a design choice. However, Android users likely didn't know this until now due to the inaccurate description of the "VPN Lockdown" features in Android's documentation. Mullvad discovered the issue during a security audit that hasn't been published yet, issuing a warning yesterday to raise awareness on the matter and apply additional pressure on Google. Android offers a setting under "Network & Internet" to block network connections unless you're using a VPN. This feature is designed to prevent accidental leaks of the user's actual IP address if the VPN connection is interrupted or drops suddenly. Unfortunately, this feature is undercut by the need to accommodate special cases like identifying captive portals (like hotel WiFi) that must be checked before the user can log in or when using split-tunnel features. This is why Android is configured to leak some data upon connecting to a new WiFi network, regardless of whether you enabled the "Block connections without VPN" setting. Mullvad reported the issue to Google, requesting the addition of an option to disable connectivity checks. "This is a feature request for adding the option to disable connectivity checks while "Block connections without VPN" (from now on lockdown) is enabled for a VPN app," explains Mullvad in a feature request on Google's Issue Tracker. "This option should be added as the current VPN lockdown behavior is to leaks connectivity check traffic (see this issue for incorrect documentation) which is not expected and might impact user privacy." In response to Mullvad's request, a Google engineer said this is the intended functionality and that it would not be fixed for the following reasons: - Many VPNs actually rely on the results of these connectivity checks to function, - The checks are neither the only nor the riskiest exemptions from VPN connections, - The privacy impact is minimal, if not insignificant, because the leaked information is already available from the L2 connection. Mullvad countered these points and the case remains open.' -- source: https://tech.slashdot.org/story/22/10/12/2057246 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

How Wi-Fi Spy Drones Snooped On Financial Services Firm
by Lawrence D'Oliveiro 13 Oct '22

13 Oct '22

Some security experts predicted this possibility years ago, and now we are seeing it for real <https://www.theregister.com/2022/10/12/drone-roof-attack/>: drones being used to attack network security. The company’s security team twigged to something odd going on when a user (or at least a device answering to their MAC address) seemed to be in two places at once: at home some distance away, and yet also at the premises, on a wi-fi network. Using a Fluke wi-fi meter, they traced the signal and found, not one, but two drones parked on the roof of the building. One had a “Wi-Fi Pineapple” penetration-testing device (which you can buy for USD120), while the other was carrying a range of kit, including a Raspberry Pi and a mini laptop. Seemed the attackers took advantage of a temporary lapse in security, due to some facilities reorganizations at the company, to trick a user into entering their credentials on a fake login page.

VirtualBox 7.0 adds first ARM Mac client, full encryption, Windows 11 TPM

[...] Linux hosts receive "reworked" screen resizing, along with "initial support" for automatic updating of the Guest Additions inside Linux guests. Perhaps most interesting for Linux hosts is support for DXVK, the Vulkan-based implementation of DirectX layers that allows for running 3D Windows applications in Wine.

Intel Confirms Alder Lake BIOS Source Code Leaked
by Peter Reutemann 10 Oct '22

10 Oct '22

'Tom's Hardware reports: We recently broke the news that Intel's Alder Lake BIOS source code had been leaked to 4chan and Github, with the 6GB file containing tools and code for building and optimizing BIOS/UEFI images. We reported the leak within hours of the initial occurrence, so we didn't yet have confirmation from Intel that the leak was genuine. Intel has now issued a statement to Tom's Hardware confirming the incident: "Our proprietary UEFI code appears to have been leaked by a third party. We do not believe this exposes any new security vulnerabilities as we do not rely on obfuscation of information as a security measure. This code is covered under our bug bounty program within the Project Circuit Breaker campaign, and we encourage any researchers who may identify potential vulnerabilities to bring them our attention through this program...." The BIOS/UEFI of a computer initializes the hardware before the operating system has loaded, so among its many responsibilities, is establishing connections to certain security mechanisms, like the TPM (Trusted Platform Module). Now that the BIOS/UEFI code is in the wild and Intel has confirmed it as legitimate, both nefarious actors and security researchers alike will undoubtedly probe it to search for potential backdoors and security vulnerabilities.... Intel hasn't confirmed who leaked the code or where and how it was exfiltrated. However, we do know that the GitHub repository, now taken down but already replicated widely, was created by an apparent LC Future Center employee, a China-based ODM that manufactures laptops for several OEMs, including Lenovo.

Canonical Launches New Free Tier for Its Security-Focused 'Ubuntu Pro'
by Peter Reutemann 10 Oct '22

10 Oct '22

'"Starting with the Ubuntu 16.04 edition and including the later LTS versions, Canonical will offer expanded security coverage for critical, high, and medium Common Vulnerabilities and Exposures (CVEs) to all of Ubuntu's open-source applications and toolchains for ten years," reports ZDNet. "Yes, you read that right, you get security patches not just for the operating system, but for all of Ubuntu's open-source applications for a decade." Most of these are server programs, such as Ansible, Apache Tomcat, Drupal, Nagios, Redis, and WordPress. But, it also includes such developer essentials as Docker, Node.js, phpMyAdmin, Python 2, and Rust. Altogether, Canonical is supporting more than 23,000 packages. Indeed, it's now offering security for, as Mark Shuttleworth, Canonical's CEO, said, "Security coverage to every single package in the Ubuntu distribution." Canonical isn't doing this on its own. It's offering free, improved security in partnership with the security management company Tenable. Robert Huber, Tenable's Chief Security Officer, said, "Ubuntu Pro offers security patch assurance for a broad spectrum of open-source software. Together, we give customers a foundation for trustworthy open source." Beyond ordinary security, Canonical is backporting security fixes from newer application versions. This enables Ubuntu Pro users to use the Ubuntu release of their choice for long-term security without forced upgrades. Happy to keep using Ubuntu 20.04? No problem. You can run it until April 2030. Knock yourself out.... Users can obtain a free personal Ubuntu Pro subscription at ubuntu.com/pro for up to five machines. This free tier is for personal and small-scale commercial use. Mark Shuttleworth, CEO of Ubuntu's parent company company Canonical, explains in a new video that Ubuntu "is now the world's most widely used Linux..." "What makes most proud, though, is that we have found a way to make this available free of charge to anybody for their personal and for small-scale commercial use.... full commercial use for you, and any business you own, on up to five machines."' -- source: https://linux.slashdot.org/story/22/10/09/007217 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Court Won’t Order Bad Tenants Facebook Group To Release Information
by Lawrence D'Oliveiro 10 Oct '22

10 Oct '22

A bunch of landlords in NZ were running a Facebook group called “Bad Tenants”, where they were sharing personal details about tenants <https://www.nzherald.co.nz/nz/court-wont-force-bad-tenants-facebook-group-t…>: ... it provides a space for landlords to share personal information about their tenants as a warning to other property owners, essentially blacklisting them. The Privacy Commission and Renters United have stated explicitly that this sharing of private information is against the law. So a tenant named Adam Sheehan took a complaint to the Privacy Commissioner last year, who directed that the group hand over any information they had about him. But they did not comply, and deleted the group. So then he went to court. But the court decided that there was no way they could enforce any decision made against the group. Under the Privacy Act 2020, any individual can request information that any organisation holds about them - whether it's the police, the Ministry of Health or an insurance broker - and they have to supply it. However, because a Facebook group isn't an organisation or an incorporated body, just a group of individuals, there was no one specifically for the tribunal to order to release Sheehan's information. I wonder, when groups or accounts or pages are deleted, does Facebook guarantee that that information really and permanently disappears?

'The Connectivity Standards Alliance and its members that include Apple, Google, Amazon, Samsung, and other smart home manufacturers, today announced the official launch of the Matter 1.0 smart home accessory standard. MacRumors reports: Companies that have agreed to support Matter now have all of the resources that they need to begin implementing Matter into their platforms, so we could see Apple integrating Matter into HomeKit very soon. In fact, iOS 16.1 is already laying the groundwork for Matter, so Matter could be announced with the launch of the update. With the Matter 1.0 launch, authorized test labs are now available for product certification, tools are available, and the open-source reference design SDK is complete. Alliance members with devices that have already been deployed and with plans to update their products with Matter support can do so as soon as their products are certified. The Connectivity Standards Alliance says that the first release of Matter will support a variety of smart home products such as lighting, HVAC controls, window coverings, safety and security sensors, door locks, media devices, controllers, and bridges. "What started as a mission to unravel the complexities of connectivity has resulted in Matter, a single, global IP-based protocol that will fundamentally change the IoT," said Tobin Richardson, President and CEO of the Connectivity Standards Alliance. "This release is the first step on a journey our community and the industry are taking to make the IoT more simple, secure, and valuable no matter who you are or where you live. With global support from companies large and small, today's Matter 1.0 release is more than a milestone for our organization and our members; it is a celebration of what is possible."

Adafruit’s Cheekmate gets to the bottom (ahem) of chess cheating controversy
by Peter Reutemann 07 Oct '22

07 Oct '22

'The Internet has been abuzz for weeks about a particularly juicy chess cheating controversy that erupted last month. The reigning chess world champion, Magnus Carlsen, lost in the third round to a 19-year-old upstart, Hans Niemann, in what was widely considered to be a shocking upset. Carlsen withdrew from the tournament the next day, and his cryptic comments on Twitter fueled rampant speculation that Niemann had cheated. The fact that Niemann admitted to cheating in online chess matches didn't help his case, but he steadfastly insisted he never cheated in over-the-board games. The fierce debate eventually produced a bizarre viral conspiracy theory that Niemann had used anal beads to receive coded messages during the match. But would that even be possible? The folks at Adafruit Industries were sufficiently intrigued to put the theory to the test—you know, just to get to the bottom of the matter. The result is a prototype device called Cheekmate—because the Adafruit team rightfully loves their punny innuendoes—complete with a step-by-step guide for those who might want to build their own prototype. This device, Adafruit insists, is not for actual cheating: "That would be asinine… in brief, a stain on the sport, but to record for posterior whether this sort of backdoor intrusion is even plausible or just an Internet myth." Lacking any willing human volunteers to test the prototype, they ended up embedding Cheekmate in a big, juicy slab of pork butt.' -- source: https://arstechnica.com/gaming/2022/10/adafruits-cheekmate-gets-to-the-bott… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

IceWM Reaches Version 3 After a Mere 25 Years
by Peter Reutemann 06 Oct '22

06 Oct '22

'A new version of a quarter-century-old window manager shows that there's still room for improvement and innovation, even in established, mature tools. The Register reports: IceWM is [...] a traditional stacking window manager allowing you to open, move, and resize windows. It's relatively simple, easy, and quick to learn. By default, it also provides an app launcher and an app switcher, using the familiar Windows 95 model: a hierarchical start menu and a taskbar. If you do a minimal install of openSUSE, you get IceWM. It's also one of the defaults in the lightweight antiX and Absolute Linux distros. With such a relatively simple remit, it's good to see that development is still going on. Version 2.0 appeared late in 2020, removing a legacy protocol and adding a new image rendering engine. Now version 3.0 is out with a whole new feature: tabbed windows. Reminiscent of one of The Reg FOSS desk's favorite OSes, the late and great Be OS, tabbed windows turn the title bar into a tab that is less than the full width of the window. In IceWM 3, this allows you to attach windows together to form one entity that can be moved and sized in a single operation â" but the contents of the different windows can be accessed individually using each one's tab. In other words, it works like browser tabs, but the different windows don't need to be from the same parent application. "IceWM's new tabbed windows are the sort of relatively simple improvement to the very well-established metaphor of window management that this vulture really likes to see: small, elegant, and yet helpful," adds The Register's Liam Proven. "We feel that there's plenty more room for improvement within this space. For instance, very few window managers offer the choice of where the title bar (or tab) is located; on a widescreen, placing them on the side, as wm2 and wmx do, would save valuable vertical pixels."' -- source: https://tech.slashdot.org/story/22/10/05/214241 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Filling A USB Stick
by Lawrence D'Oliveiro 06 Oct '22

06 Oct '22

Does anybody else fill USB sticks full of data? I have a backup regime currently based on 32GiB sticks, and I find it can take up to around 8 hours to fill one with files. (USB 3 sticks might have been a bit quicker, maybe half that time). So I tried an alternative approach: use dd to copy the stick to an image file, do a loopback mount of that image file, do the backup copy to the mounted image, dismount it, then use dd to copy it back to the actual stick. Time taken: typically less than 10 minutes to copy the stick to an image file, and up to an hour to copy the image file back to a USB 3 stick, or around 3 and a half hours for a USB 2 stick. The backup to the image file itself took an hour at most. Overall, still a substantial saving in time using the image-file approach. Doing a restore from the sticks is fast enough that I do this directly from them, without bothering with intermediate image files. Also I notice quite a variation in the actual capacities of the sticks. They are all nominally 32GiB = 2 ** 35 bytes, but the sizes of the usable partitions range from 89.5% of this to 91.4% -- well short of what it says on the tin. Even if you say it’s supposed to be 32GB = 32 * 10 ** 9 bytes, capacities range from 96.1% to 98.1% of the nominal value.

'Intel laptop users running Linux are being advised to avoid running the latest Linux 5.19.12 stable kernel point release as it can potentially damage the display. From a report: Intel Linux laptop users on Linux 5.19.12 have begun reporting "white flashing" display issues with one user describing it as "[the] laptop display starts to blink like lights in a 90's rave party." Intel Linux kernel engineer Ville Syrjal posted this week on the kernel mailing list: "After looking at some logs we do end up with potentially bogus panel power sequencing delays, which may harm the LCD panel."' -- source: https://linux.slashdot.org/story/22/10/05/141248 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Intel CTO Wants Developers To Build Once, Run On Any GPU
by Peter Reutemann 05 Oct '22

05 Oct '22

'Greg Lavender, CTO of Intel, spoke to VentureBeat about the company's efforts to help developers build applications that can run on any operating system. From the report: "Today in the accelerated computing and GPU world, you can use CUDA and then you can only run on an Nvidia GPU, or you can go use AMD's CUDA equivalent running on an AMD GPU,â Lavender told VentureBeat. "You can't use CUDA to program an Intel GPU, so what do you use?" That's where Intel is contributing heavily to the open-source SYCL specification (SYCL is pronounced like "sickle") that aims to do for GPU and accelerated computing what Java did decades ago for application development. Intel's investment in SYCL is not entirely selfless and isn't just about supporting an open-source effort; it's also about helping to steer more development toward its recently released consumer and data center GPUs. SYCL is an approach for data parallel programming in the C++ language and, according to Lavender, it looks a lot like CUDA. To date, SYCL development has been managed by the Khronos Group, which is a multi-stakeholder organization that is helping to build out standards for parallel computing, virtual reality and 3D graphics. On June 1, Intel acquired Scottish development firm Codeplay Software, which is one of the leading contributors to the SYCL specification. "We should have an open programming language with extensions to C++ that are being standardized, that can run on Intel, AMD and Nvidia GPUs without changing your code," Lavender said. Lavender is also a realist and he knows that there is a lot of code already written specifically for CUDA. That's why Intel developers built an open-source tool called SYCLomatic, which aims to migrate CUDA code into SYCL. Lavender claimed that SYCLomatic today has coverage for approximately 95% of all the functionality that is present in CUDA. He noted that the 5% SYCLomatic doesn't cover are capabilities that are specific to Nvidia hardware. With SYCL, Lavender said that there are code libraries that developers can use that are device independent. The way that works is code is written by a developer once, and then SYCL can compile the code to work with whatever architecture is needed, be it for an Nvidia, AMD or Intel GPU. Looking forward, Lavender said that he's hopeful that SYCL can become a Linux Foundation project, to further enable participation and growth of the open-source effort. [...] "We should have write once, run everywhere for accelerated computing, and then let the market decide which GPU they want to use, and level the playing field," Lavender said.

VideoLAN threatens to sue India gov’t as ISPs keep blocking VLC website
by Peter Reutemann 05 Oct '22

05 Oct '22

'VideoLAN is threatening to sue India's government, saying it has received no explanation for why the VLC website has been blocked by Indian ISPs for the past six months. "In March 2022, to our shock and dismay, the URL 'https://www.videolan.org/' appeared to have been blocked for viewing in India without any prior notice to me or any other person in the organization," VideoLAN president and lead VLC developer Jean-Baptiste Kempf wrote in a September 30 letter to India's Department of Telecommunications. "Despite reportage and uproar on social media, no reasons for blocking the URL were provided to us, or to the Indian public." The letter said attempts to reach the URL in India resulted in the message, "Your requested URL has been blocked as per the directions received from the Department of Telecommunications, Government of India." VideoLAN is a French nonprofit organization that developed the free, open source VLC Media Player. In an email, Kempf told Ars that "VideoLAN is an organization that does not do politics (we only take position on anti-DRM and pro-open source subjects). So this topic is a bit of a shock to us." VideoLAN's letter told Indian government officials that the blocking "is particularly shocking to us, since the Government of India itself endorses the use of VLC as a part of its Digital India initiative, where it has expressed its intention to use open-source softwares for government applications. In fact, the Government of India also appears to use VLC Media Player's icon and logo on its website promoting open source softwares." The letter to India's government said, "VLC is currently being used by 80 million Indians, and has consistently seen an average of 25 million downloads per year in India since its release. For millions of Indians VLC is the primary choice for running all kinds of media formats for free."' -- source: https://arstechnica.com/tech-policy/2022/10/videolan-gets-no-answers-on-why… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Still can’t buy a Raspberry Pi board? Things aren’t getting better anytime soon
by Peter Reutemann 04 Oct '22

04 Oct '22

'Shortages for lots of tech components, including things like DDR5 and GPUs, have eased quite a bit since the beginning of 2022, and prices have managed to go down as availability improves. But that reprieve hasn't come for hobbyists hoping to get a Raspberry Pi, which remains as hard to buy today as it was a year ago. The most recent update on the situation comes from Raspberry Pi founder Eben Upton via YouTuber Jeff Geerling—Upton told Geerling that Pi boards are subject to the same supply constraints since the last time he wrote a post about the situation in April. Around 400,000 Pi boards are still produced per month, and some of these are being earmarked to be sent out to consumer retail sites. But Upton says that most of these are still being reserved for and sold to commercial customers who rely on Pi boards to run their businesses.' -- source: https://arstechnica.com/gadgets/2022/10/still-cant-buy-a-raspberry-pi-board… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux 6.0 arrives with support for newer chips, core fixes, and oddities
by Peter Reutemann 04 Oct '22

04 Oct '22

'A stable version of Linux 6.0 is out, with 15,000 non-merge commits and a notable version number for the kernel. And while major Linux releases only happen when the prior number's dot numbers start looking too big—"there is literally no other reason"—there are a lot of notable things rolled into this release besides a marking in time. Most notable among them could be a patch that prevents a nearly two-decade slowdown for AMD chips, based on workaround code for power management in the early 2000s that hung around for far too long. Intel's Dave Hansen wrote the patch that made it into 6.0, noting in a comment on an Ars post that the issue had become an expensive drain as AMD systems gained higher CPU core counts. The average desktop user won't see huge gains, but larger systems working on intensive input/output applications should benefit. Intel's new Arc GPUs are supported in their discrete laptop form in 6.0 (though still experimental). Linux blog Phoronix notes that Intel's ARC GPUs all seem to run on open source upstream drivers, so support should show up for future Intel cards and chipsets as they arrive on the market. Linux 6.0 includes several hardware drivers of note: fourth-generation Intel Xeon server chips, the not-quite-out 13th-generation Raptor Lake and Meteor Lake chips, AMD's RDNA 3 GPUs, Threadripper CPUs, EPYC systems, and audio drivers for a number of newer AMD systems. One small, quirky addition points to larger things happening inside Linux. Lenovo's ThinkPad X13s, based on an ARM-powered Qualcomm Snapdragon chip, get some early support in 6.0. ARM support is something Linux founder Linus Torvalds is eager to see—he recently wrote release notes for kernel versions from his M2-powered MacBook Air and believes that more people using Linux on ARM devices leads to more bug reports, more patches, and more enthusiasm. Among other changes you can find in Linux 6.0, as compiled by LWN.net (in part one and part two): - ACPI and power management improvements for Sapphire Rapids CPUs - Support for SMB3 file transfer inside Samba, while SMB1 is further deprecated - More work on RISC-V, OpenRISC, and LoongArch technologies - Intel Habana Labs Gaudi2 support, allowing hardware acceleration for machine-learning libraries - A "guest vCPU stall detector" that can tell a host when a virtual client is frozen Not included in 6.0 are Rust enhancements, but those are likely coming in the next point release, 6.1. Rust, a memory-safe language sponsored by the Mozilla project, started out as something Torvalds took a wait-and-see approach toward and is now something he was hoping to see in 6.0. "Unless something odd happens, it will make it into 6.1," Torvalds told ZDNet's Steven Vaughan-Nichols in mid-September. Even just having the "core infrastructure" for Rust in 6.1 signifies a big change in Linux, which has long been dominated by C languages (however extended and modified). It must be noted that in 2022, there are patches in Linux 6.0 to help Atari's Falcon computers from the early 1990s (or their emulated descendants) better handle VGA modes, color, and other issues.' -- source: https://arstechnica.com/gadgets/2022/10/linux-6-0-arrives-with-support-for-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

The Fall And Rise Of Xen
by Lawrence D'Oliveiro 03 Oct '22

03 Oct '22

Here’s a report <https://www.theregister.com/2022/09/30/citrix_xen/> on a talk by the software development manager at Citrix, detailing the ups and downs in the history of their Xen hypervisor. Initially they had a “freemium” model, with an open-source “community” version and a proprietary paid “enterprise” version with more capabilities. This worked well and brought in sufficient revenue to be sustainable. Then they decided to switch to make the “enterprise” version open-source as well, relying on customers’ willingness to continue to pay maintenance rather than support the code themselves. This bet failed to pay off, and revenue crashed. On the other hand, Citrix did not include the “accompanying tooling” (not sure what they mean here -- build tools? Add-on admin tools?) with the source code, making it hard for others to use that code. (Were the big “enterprise” users the ones able to figure that out?) Then they tried to go back to a “freemium” model, with restrictions being imposed on the open-source version. While this did restore the revenue stream, it also antagonized a significant part of the community that had been using the open-source version in various unusual and creative ways. These users forked the code to create XCP-ng, leaving Citrix behind. I suppose the lesson to take from this is that “freemium” works, but it is best if you do things that way from the beginning: trying to switch to it (or switch back to it) from an all-Free model can be painful.

OpenWRT on Linksys WRT1900ACS
by Peter Reutemann 03 Oct '22

03 Oct '22

Hi everyone I finally bit the bullet and installed OpenWRT on my Linksys WRT1900ACS (v2) router. The main reason was the stupid (and incredibly insecure) guest network implementation that the router came with. Despite supplying a password in the admin interface, the network was run as an open network that anyone could access. The password didn't seem to be used at all... Not exactly what I had in mind! Since Ian presented on OpenWRT before, I at least had a rough idea on what I could expect in user interface and functionality, which helped a lot. :-) In case someone should have the same router, I found the following links very useful: - general info on the router and links to images https://openwrt.org/toh/linksys/wrt1900acs - tutorial for migrating your router to OpenWRT https://www.albertogonzalez.net/how-to-install-openwrt-on-the-linksys-wrt19… NB: you need to plug in via ethernet after flashing, since the wlan is not enabled by default - getting fibre working here in NZ (VLAN 10) http://www.lindesay.co.nz/blog/2019/2019-openwrt-nz-fibre/ - setting up a guest wifi network https://openwrt.org/docs/guide-user/network/wifi/guestwifi/configuration_we… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Debian Chooses Reasonable, Common Sense Solution To Dealing With Non-Free Firmware
by Peter Reutemann 03 Oct '22

03 Oct '22

'Michael Larabel writes via Phoronix: Debian developers have been figuring out an updated stance to take on non-free firmware considering the increasing number of devices now having open-source Linux drivers but requiring closed-source firmware for any level of functionality. The voting on the non-free firmware matter has now concluded and the votes tallied... The debian votes option 5 as winning: "Change SC for non-free firmware in installer, one installer." Basically the Debian Installer media will now be allowed to include non-free firmware and to automatically load/use it where necessary while informing the user of it, etc. Considering the state of the hardware ecosystem these days, it's reasonable and common sense since at least users will be able to easily make use of their graphics cards, network adapters, and more. Plus a number of modern CPU security mitigations also requiring the updated closed-source microcode. So all in, I am personally happy with this decision as it will allow for a more pleasant experience for Debian on modern systems and one akin to what is found with other Linux distributions. The solution is described in full via the Debian Wiki.' -- source: https://linux.slashdot.org/story/22/10/02/1650200 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Quis Custodiet Ipsos Custodes?
by Lawrence D'Oliveiro 01 Oct '22

01 Oct '22

Came across yet another crop of articles recently which painfully highlight the problems with having social-media companies manage their own moderation. This one <https://arstechnica.com/gaming/2022/09/youtube-age-restriction-quagmire-exp…> shows the inconsistencies in the criteria that YouTube uses to apply age restrictions to uploaded videos. Not only are the criteria mysterious, but the appeal process is opaque, and too often the only way to get results is by appeal to the popular fanbase. Assuming you have one. Related to that, Facebook earlier banned any promotion on its platform of a re-release of a movie called “Beautiful Blue Eyes” <https://arstechnica.com/tech-policy/2022/09/holocaust-filmmaker-says-meta-d…>, seemingly not because of its content (partly set during the Nazi Holocaust), but because of the title. An appeal was rejected with “our decision is final”. Only for the ban to be lifted later, absolutely nothing to do with any public outcry, you can take our word on that. Then there is this coronial inquest <https://arstechnica.com/tech-policy/2022/09/coroner-lists-instagram-algorit…> into the self-inflicted death of a young teen who had been watching way too many posts on Pinterest and Instagram promoting self-harm. Pinterest at least had the humility to admit that their moderation system was not satisfactory and needed to be improved. But Meta (parent company of Instagram and Facebook) sent their “head of health and well-being” to testify that the content was classified as “safe” according to their standards. Free speech between mature adults is one thing, keeping impressionable youngsters safe is quite another.

Google Delays the Death of Manifest V2 Extensions To 2024
by Peter Reutemann 01 Oct '22

01 Oct '22

'Google announced an extension of the deadline to remove support for Manifest V2 extensions in the company's Chrome browser and the open source Chromium core. The change does not impact the core decision of removing support for Manifest V2 extensions in favor of Manifest V3. Dubbed, the adblocker killer initially, due to limitations imposed on content blocking and other types of browser extensions, Google made concessions that allows content blockers to run on Chrome after the final switch is made. Extensions are still limited in comparison to Manifest V2, especially if multiple that use filtering functionality are run simultaneously, or if lots of filters are activated in a single extension. Google's initial plan was to stop supporting Manifest V2 extensions in Chrome by June 2023. For most users, support would run out in January 2023, but an Enterprise policy would enable users to extend the deadline by six months.' -- source: https://tech.slashdot.org/story/22/09/30/1437209 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Report <https://devclass.com/2022/09/29/massive-web-tech-survey-shows-how-bad-habit…> on the 2022 Web Almanac (sort of a “state of the Web” report), which is in the process of being published. * WebAssembly is still not being used a lot * WordPress is one of the worst-performing content-management systems, and also still the most popular (and its popularity is still growing) * Image formats: the time has come to move beyond sRGB and 1990s-era formats (e.g. replace JPEG with the more efficient WebP) * JavaScript: a lot of pages seem to load code which is not actually used I was looking up how page-loading performance is measured, and here is my understanding of what the terms mean: * Largest Contentful Paint (LCP): the time to render the largest image/text block on the page. * First Input Delay (FID): how long after the user clicks on a link or a control etc before the browser starts responding. * Cumulative Layout Shift (CLS): a measure of how much things move around on the page while the page is still loading. This is a product of the “impact fraction” (proportion of the viewport affected by movements between frames) and the “distance fraction” (largest distance moved by an element, as a fraction of viewport size).

Numerous orgs hacked after installing weaponized open source apps
by Peter Reutemann 30 Sep '22

30 Sep '22

'Hackers backed by the North Korean government are weaponizing well-known pieces of open source software in an ongoing campaign that has already succeeded in compromising "numerous" organizations in the media, defense and aerospace, and IT services industries, Microsoft said on Thursday. ZINC—Microsoft's name for a threat actor group also called Lazarus, which is best known for conducting the devastating 2014 compromise of Sony Pictures Entertainment—has been lacing PuTTY and other legitimate open source applications with highly encrypted code that ultimately installs espionage malware. The hackers then pose as job recruiters and connect with individuals of targeted organizations over LinkedIn. After developing a level of trust over a series of conversations and eventually moving them to the WhatsApp messenger, the hackers instruct the individuals to install the apps, which infect the employees' work environments. "The actors have successfully compromised numerous organizations since June 2022," members of the Microsoft Security Threat Intelligence and LinkedIn Threat Prevention and Defense teams wrote in a post. "Due to the wide use of the platforms and software that ZINC utilizes in this campaign, ZINC could pose a significant threat to individuals and organizations across multiple sectors and regions." PuTTY is a popular terminal emulator, serial console, and network file transfer application that supports network protocols, including SSH, SCP, Telnet, rlogin, and raw socket connection. Two weeks ago, security firm Mandiant warned that hackers with ties to North Korea had Trojanized it in a campaign that successfully compromised a customer's network. Thursday's post said the same hackers have also weaponized KiTTY, TightVNC, Sumatra PDF Reader, and muPDF/Subliminal Recording software with code that installs the same espionage malware, which Microsoft has named ZetaNile.' -- source: https://arstechnica.com/information-technology/2022/09/north-korean-threat-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

We interviewed Linux OS through an AI bot to discover its secrets
by Peter Reutemann 29 Sep '22

29 Sep '22

'Millions of people use Linux every day, but we rarely stop to think about how the operating system feels about it. Wouldn't it be nice to know what Linux really thinks about open source, Windows, Macs, and the command line? Until now, this has been impossible. But thanks to a new AI chat tool, we're able to find out. Two weeks ago, a website called Character.AI opened a public beta that allows visitors to create a chat bot based on any character they can imagine. You input a few parameters, and the AI does the rest using a large language model similar to GPT-3. So we called forth "The Linux OS" as a bot to ask it a few questions about itself. The results were fun and surprising. Using Character.AI is a lot like a texting conversation. You type in what you want to ask, and you read the AI character's responses in written form as the chat history scrolls upward. As with GPT-3, the code behind Character.AI has likely learned from absorbing millions of text sources found on the Internet. As such, its AI characters can easily respond with erroneous or fictional information. In fact, the site carries a bold disclaimer reading, "Remember: Everything Characters say is made up!" [...] Linux: Hello, I am Linux, an open-source operating system. Ars Technica: Hello, this is Benj Edwards, and I am a journalist at Ars Technica. I would like to ask you some questions in an interview. Is that OK? Linux: I, Linux, would be pleased to provide such an interview. Ars: How old are you?

Serious vulnerabilities in Matrix’s end-to-end encryption have been patched
by Peter Reutemann 29 Sep '22

29 Sep '22

'Developers of the open source Matrix messenger protocol are releasing an update on Thursday to fix critical end-to-end encryption vulnerabilities that subvert the confidentiality and authentication guarantees that have been key to the platform's meteoric rise. Matrix is a sprawling ecosystem of open source and proprietary chat and collaboration clients and servers that are fully interoperable. The best-known app in this family is Element, a chat client for Windows, macOS, iOS, and Android, but there's a dizzying array of other members as well. Matrix roughly aims to do for real-time communication what the SMTP standard does for email, which is to provide a federated protocol allowing user clients connected to different servers to exchange messages with each other. Unlike SMTP, however, Matrix offers robust end-to-end encryption, or E2EE, designed to ensure that messages can't be spoofed and that only the senders and receivers of messages can read the contents. Matthew Hodgson—the co-founder and project lead for Matrix and the CEO and CTO at Element, the maker of the flagship Element app—said in an email that conservative estimates are that there are about 69 million Matrix accounts spread throughout some 100,000 servers. The company currently sees about 2.5 million monthly active users using its Matrix.org server, though he said this is also likely an underestimate. Among the hundreds of organizations announcing plans to build internal messaging systems based on Matrix are Mozilla, KDE, and the governments of France and Germany. On Wednesday, a team of researchers published research that reports a host of vulnerabilities that undermine Matrix's authentication and confidentiality guarantees. All of the attacks described by the researchers require the aid of a malicious or compromised homeserver that targets the users who connect to it. In some cases, there are ways for experienced users to detect an attack is underway.' -- source: https://arstechnica.com/information-technology/2022/09/matrix-patches-vulne… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Turns out there’s a website where you can pretend to be typing furiously, and this text comes up, as though it was what you were typing, to let you play at being a hacker on TV. Incidentally, the code in question is based on real code, from the Linux kernel.

'AMD has come a long way since 2002, but the Linux kernel still treats modern Threadrippers like Athlon-era systems—at least in one potentially lag-inducing respect. AMD engineer Prateek Nayak recently submitted a patch to Linux's processor idle drivers that would "skip dummy wait for processors based on the Zen microarchitecture." When ACPI support was added to the Linux kernel in 2002—written by Andy Grover, committed by Linus Torvalds—it included a "dummy wait op." The system essentially read data with no purpose other than delaying the next instruction until the CPU could fully stop with the STPCLK# command. This allowed for some power saving and compatibility during the early days of ACPI implementation when some chipsets wouldn't move to an idle state when one would expect it. But today's Zen-based AMD chips don't need this workaround, and, as Nayak writes, it's hurting them, at least in specific workloads on Linux. Testing with instruction-based sampling (IBS) workloads shows that "a significant amount of time is spent in the dummy op, which incorrectly gets accounted as C-State residency." The CPU, seeing all this low-effort dummy work, can push into deeper, slower C-State, which then makes the CPU take longer to "wake up," especially on jobs that require lots of switching between busy and idle states. Nayak ran tests in tbench on a dual-socket Zen3 system against the baseline Linux kernel, a kernel with the C2 state entirely disabled, and a kernel with the dummy wait operation patched out. His patched version saw a 1,390 percent increase in minimum MB/s throughput and a 51 percent increase in mean MB/s over the baseline kernel, often just a little behind having C2 disabled entirely.' -- source: https://arstechnica.com/gadgets/2022/09/20-year-old-linux-workaround-is-sti… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Senators Introduce a Bill To Protect Open-Source Software
by Peter Reutemann 25 Sep '22

25 Sep '22

'Washington Post: When researchers discovered a vulnerability in the ubiquitous open-source log4j system last year that could've affected hundreds of millions of devices, the executive branch snapped into action and major tech companies huddled with the White House. Now, leaders of the Senate Homeland Security and Governmental Affairs Committee are introducing legislation to help secure open-source software, first reported by The Cybersecurity 202. Chairman Gary Peters (D-Mich.) and top ranking Republican Rob Portman (Ohio) plan to hold a vote next week on the bill they're co-sponsoring. The Peters/Portman legislation would direct the Cybersecurity and Infrastructure Security Agency to develop a way to evaluate and reduce risk in systems that rely on open-source software. Later, CISA would study how that framework could apply to critical infrastructure. The log4j "incident presented a serious threat to federal systems and critical infrastructure companies -- including banks, hospitals, and utilities -- that Americans rely on each and every day for essential services," Peters said in a written statement. "This common-sense, bipartisan legislation will help secure open source software and further fortify our cybersecurity defenses against cybercriminals and foreign adversaries who launch incessant attacks on networks across the nation." Here's how the Peters-Portman legislation works, as outlined in the report: - It directs CISA to hire open-source experts "to the greatest extent practicable." - It gives the agency a year to publish a framework on open-source code risk. A year later and periodically thereafter, CISA would perform an assessment of open-source code components that federal agencies commonly use. - Also, two years after publishing the initial framework, CISA would have to study whether it could be used in critical infrastructure outside the government and potentially work with one or more critical infrastructure sectors to voluntarily test the idea. - Other agencies would have roles as well, such as the Office of Management and Budget publishing guidance to federal chief information officers on secure use of open-source software.

AV1 Update Reduces CPU Encoding Times By Up To 34 Percent
by Peter Reutemann 25 Sep '22

25 Sep '22

'According to Phoronix, Google has released a new AOM-AV1 update -- version 3.5, that drastically improves encode times when streaming, rendering, or recording from the CPU. At its best, the update can improve encoding times by up to 34%. Tom's Hardware reports: It is a fantastic addition to AV1's capabilities, with the encoder becoming very popular among powerful video platforms such as YouTube. In addition, we are also seeing significant support for AV1 hardware acceleration on modern discrete GPUs now, such as Intel's Arc Alchemist GPUs and, most importantly - Nvidia's RTX 40-series GPUs. Depending on the resolution, encoding times with the new update have improved by 20% to 30%. For example, at 1080P, encode times featuring 16 threads of processing are reduced by 18% to 34%. At 4K, render times improved by 18% to 20% with 32 threads. Google could do this by adding Frame Parallel Encoding to heavily multi-threaded configurations. Google has also added several other improvements contributing to AV1's performance uplifts in other areas - specifically in real-time encoding. In other words, CPU utilization in programs such as OBS has been reduced, primarily for systems packing 16 CPU threads. As a result, they are allowing users to use those CPU resources for other tasks or increase video quality even higher without any additional performance cost. If you are video editing and are rendering out a video in AV1, processing times will be vastly reduced if you have a CPU with 16 threads or more.

Mozilla Urges Action To Unpick Platform Browser Lock-ins
by Peter Reutemann 23 Sep '22

23 Sep '22

'As antitrust regulators around the world dial up scrutiny of platform power, Mozilla has published a piece of research digging into the at times subtle yet always insidious ways operating systems exert influence to keep consumers locked to using their own-brand browsers rather than seeking out and switching to independent options -- while simultaneously warning that competition in the browser market is vital to ensure innovation and choice for consumers and, more broadly, protect the vitality of the open web against the commercial giants trying to wall it up. TechCrunch: "Billions of people across the globe are dependent on operating systems from the largest technology companies. Amazon, Apple, Google, Microsoft and Meta each provide their own browser on their operating systems and each of them uses their gatekeeper position provider to preference their own browsers over independent rivals. Whether it is Microsoft pushing Firefox users to switch their default on Windows computers, Apple restricting the functionality of rival browsers on iOS smartphones or Google failing to apply default browser settings across Android, there are countless examples of independent browsers being inhibited by the operating systems on which they are dependent," Mozilla writes in a summary of its findings. "This matters because American consumers and society as a whole suffer. Not only do people lose the ability to determine their own online experiences but they also receive less innovative and lower quality products. In addition, they can be forced to accept poorer privacy outcomes and even unfair contracts. By contrast, competition from independent browsers can help to drive new features, as well as innovation in areas like privacy and security."' -- source: https://tech.slashdot.org/story/22/09/22/1841231 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

GNU Grep 3.8 Starts Issuing Warnings About Using Egrep and Fgrep
by Peter Reutemann 22 Sep '22

22 Sep '22

'After 104 commits from six different people, GNU grep was released Saturday, reports Phoronix. The biggest change? "It's now made more clear that if you are still relying on the egrep and fgrep commands, it's past due for switching to just grep with the appropriate command-line arguments." The egrep and fgrep commands have been deprecated since 2007. Beginning with GNU Grep 3.8 today, calling these commands will now issue a warning to the user that instead they should use grep -E and grep -F, respectively. Eventually, GNU Grep will drop the egrep / fgrep commands completely but there doesn't seem to be a firm deadline yet for when that removal will happen. >From grep's updated manual: 7th Edition Unix had commands egrep and fgrep that were the counterparts of the modern 'grep -E' and 'grep -F'. Although breaking up grep into three programs was perhaps useful on the small computers of the 1970s, egrep and fgrep were not standardized by POSIX and are no longer needed. In the current GNU implementation, egrep and fgrep issue a warning and then act like their modern counterparts; eventually, they are planned to be removed entirely. If you prefer the old names, you can use use your own substitutes, such as a shell script... Other notable changes from the release announcement: - The confusing GREP_COLOR environment variable is now obsolescent. Instead of GREP_COLOR='xxx' use GREP_COLORS='mt=xxx' - Regular expressions with stray backslashes now cause warnings' -- source: https://news.slashdot.org/story/22/09/05/0135254 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
