Microsoft Edge is Leaking the Sites You Visit To Bing
by Peter Reutemann 26 Apr '23

26 Apr '23

'Microsoft's Edge browser appears to be sending URLs you visit to its Bing API website. Reddit users first spotted the privacy issues with Edge last week, noticing that the latest version of Microsoft Edge sends a request to bingapis.com with the full URL of nearly every page you navigate to. Microsoft tells The Verge it's investigating the reports. From a report: "Searching for references to this URL give very few results, no documentation on this feature at all," said hackermchackface, the Reddit user who first discovered the issue. While Reddit users weren't able to uncover why Microsoft Edge is sending the URLs you visit to its Bing API site, we asked Rafael Rivera, a software engineer and one of the developers behind EarTrumpet, to investigate, and he discovered it's part of a poorly implemented new feature in Edge. "Microsoft Edge now has a creator follow feature that is enabled by default," says Rivera in a conversation with The Verge. "It appears the intent was to notify Bing when you're on certain pages, such as YouTube, The Verge, and Reddit. But it doesn't appear to be working correctly, instead sending nearly every domain you visit to Bing."' -- source: https://yro.slashdot.org/story/23/04/25/209254 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/

Red Hat Begins Cutting 'Hundreds of Jobs'
by Peter Reutemann 25 Apr '23

25 Apr '23

'According to Phoronix citing multiple local North Carolina news outlets, Red Hat is cutting "hundreds of jobs" in an initial round of layoffs announced today. From the report: According to WRAL, Red Hat CEO Matt Hicks is said to have told employees in an email "we will not reduce roles directly selling to customers or building our products," which is hopefully good news for their many upstream Linux developers they employ that ultimately build Red Hat Enterprise Linux and associated software products. Red Hat will begin notifying affected employees today in some countries while the process will continue through the end of the quarter. IBM, which acquired Red Hat in 2019, has already slashed some five thousand positions so far in 2023.' -- source: https://linux.slashdot.org/story/23/04/24/2220256 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/

This <https://www.theregister.com/2023/04/24/windows_frontline_cloudpc_sustainabi…> sounds like a way for Microsoft to get more revenue from users buying fewer PCs. I wonder how long it will be before Intel and the major PC vendors put a stop to this kind of talk?

Mango Pi RISC-V Single Board Computer
by Lawrence D'Oliveiro 24 Apr '23

24 Apr '23

Here is an entertaining walkthrough from Christopher Barnatt on the ever-dependable “Explaining Computers” channel of a single-core RISC-V-based board with the same tiny dimensions as a Raspberry Pi Zero W <https://www.youtube.com/watch?v=-g18PMjjlcc>. Hardly a speed demon, but for the price, I think it represents amazing value. Also a clear indication that RISC-V is fulfilling its promise of being a serious competitor, or even a successor, to ARM.

Proton Launches an End-to-End Encrypted Password Manager
by Peter Reutemann 21 Apr '23

21 Apr '23

'Proton, the company behind Proton Mail, has announced the launch of a new password manager: Proton Pass. While the service will eventually become free for everyone to use, it's currently only available as a beta to Proton's Lifetime and Visionary users for now. From a report: As is the case with Proton's other products, Proton Pass uses end-to-end encryption (E2EE) that's supposed to keep your personal information away from prying eyes, including third parties and Proton itself. In addition to letting you store your usernames, passwords, and notes, you can also add any randomly generated email aliases that you can use as a replacement for your real address. Proton's new password manager not only applies E2EE to your passwords but also the usernames, web addresses, and all the other fields associated with your login information. In a blog post explaining the service's security model, Proton notes that "all cryptographic operations, including key generation and data encryption," happen locally on your device, which Protons says it can't decrypt, even if a third party requests it.' -- source: https://yro.slashdot.org/story/23/04/20/1840225 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/

FSF Says Google's Decision to Deprecate JPEG-XL Emphasizes Need for Browser Choice
by Peter Reutemann 17 Apr '23

17 Apr '23

'"The fact remains that Google Chrome is the arbiter of web standards," argues FSF campaigns manager Greg Farough (while adding that Firefox, "through ethical distributions like GNU IceCat and Abrowser, can weaken that stranglehold.") "Google's deprecation of the JPEG-XL image format in February in favor of its own patented AVIF format might not end the web in the grand scheme of things, but it does highlight, once again, the disturbing amount of control it has over the platform generally." Part of Google's official rationale for the deprecation is the following line: "There is not enough interest from the entire ecosystem to continue experimenting with JPEG-XL." Putting aside the problematic aspects of the term "ecosystem," let us remark that it's easy to gauge the response of the "entire ecosystem" when you yourself are by far the largest and most dangerous predator in said "ecosystem." In relation to Google's overwhelming power, the average web user might as well be a microbe. In supposedly gauging what the "ecosystem" wants, all Google is really doing is asking itself what Google wants... While we can't link to Google's issue tracker directly because of another freedom issue — its use of nonfree JavaScript — we're told that the issue regarding JPEG-XL's removal is the second-most "starred" issue in the history of the Chromium project, the nominally free basis for the Google Chrome browser. Chromium users came out of the woodwork to plead with Google not to make this decision. It made it anyway, not bothering to respond to users' concerns. We're not sure what metric it's using to gauge the interest of the "entire ecosystem," but it seems users have given JPEG-XL a strong show of support. In turn, what users will be given is yet another facet of the web that Google itself controls: the AVIF format. As the response to JPEG-XL's deprecation has shown, our rallying together and telling Google we want something isn't liable to get it to change its mind. It will keep on wanting what it wants: control; we'll keep on wanting what we want: freedom. Only, the situation isn't hopeless. At the present moment, not even Google can stop us from creating the web communities that we want to see: pages that don't run huge chunks of malicious, nonfree code on our computers. We have the power to choose what we run or do not run in our browsers. Browsers like GNU IceCat (and extensions like LibreJS and JShelter> ) help with that. Google also can't prevent us from exploring networks beyond the web like Gemini. What our community can do is rally support behind those free browsers that choose to support JPEG-XL and similar formats, letting the big G know that even if we're smaller than it, we won't be bossed around.' -- source: https://news.slashdot.org/story/23/04/16/002204 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 Spectre-Related 'Medium Severity' Flaw Patched in Linux Kernel
by Peter Reutemann 17 Apr '23

17 Apr '23

'"The Spectre vulnerability that has haunted hardware and software makers since 2018 continues to defy efforts to bury it," reports the Register: On Thursday, Eduardo (sirdarckcat) Vela Nava, from Google's product security response team, disclosed a Spectre-related flaw in version 6.2 of the Linux kernel. The bug, designated medium severity, was initially reported to cloud service providers — those most likely to be affected — on December 31, 2022, and was patched in Linux on February 27, 2023. "The kernel failed to protect applications that attempted to protect against Spectre v2, leaving them open to attack from other processes running on the same physical core in another hyperthread," the vulnerability disclosure explains. The consequence of that attack is potential information exposure (e.g., leaked private keys) through this pernicous problem.... Spectre v2 — the variant implicated in this particular vulnerability — relies on timing side-channels to measure the misprediction rates of indirect branch prediction in order to infer the contents of protected memory. That's far from optimal in a cloud environment with shared hardware... The bug hunters who identified the issue found that Linux userspace processes to defend against Spectre v2 didn't work on VMs of "at least one major cloud provider."' -- source: https://linux.slashdot.org/story/23/04/16/0143259 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 Releases Emergency Chrome Security Update
by Peter Reutemann 17 Apr '23

17 Apr '23

'"Earlier this week, Google released an emergency security update for the Chrome browser due to a vulnerability that is being actively exploited in the wild," reports Hot Hardware: On Friday, Google highlighted CVE-2023-2033, reported by Clément Lecigne of Google's own Threat Analysis Group (TAG). This vulnerability is a 'type confusion' bug in the JavaScript engine for Chromium browsers useing the V8 Javascript engine. In short, type confusion is a bug that allows memory to be accessed with the wrong type, allowing for the reading or writing of memory out of bounds. The CVE page says that an attacker could create an HTML page that allows the exploitation of heap corruption. While there is no Common Vulnerability Scoring System (CVSS) score attached to the vulnerability yet, Google is tracking this as a "high" severity issue. This is likely due in part to the fact that "Google is aware that an exploit for CVE-2023-2033 exists in the wild." The article notes that Chrome updates are generally done automatically, but you can also check for updates by clicking Chrome's three-dots menu in the top-right corner, then "Help" and "About Chrome."' -- source: https://it.slashdot.org/story/23/04/16/2057239 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 Feeling Competition From Linux In ... Gaming?!?
by Lawrence D'Oliveiro 14 Apr '23

14 Apr '23

Here’s another interesting development in the Windows-Linux rivalry: in gaming, of all places. The Steam Deck is a Linux-based handheld gaming PC which could, in principle, run Windows. Trouble is, Windows doesn’t offer any good UI options for working with this form factor <https://arstechnica.com/gadgets/2023/04/handheld-mode-for-windows-could-mak…>. So there is talk of developing a new “handheld mode” for Windows. Of course, for Linux, there is no “mode” in the OS for this, it’s just a different configuration of the GUI layer. Which is modular and completely replaceable.

New Attack On Car Security: “CAN Injection”
by Lawrence D'Oliveiro 07 Apr '23

07 Apr '23

CANbus is a mini-LAN built into every car manufactured this century. It is increasingly being used for all kinds of functions, like controlling “smart headlamps”, and of course unlocking the doors and letting you get into the car and drive off. Now it turns out that there are ways to connect to the bus through weak points from outside the vehicle, for example by breaking into the connections for those “smart headlamps”. From here, you can do things like spoof signals from the smart key receiver, fooling the security system into thinking it has received a signal from a valid owner’s key when it hasn’t. And once you’ve done that, you can steal the car. Because, of course, components on the bus are trusting the signals they get from other components, aren’t they? <https://www.theregister.com/2023/04/06/can_injection_attack_car_theft/>

'A report from 9to5Linux: The Ubuntu Cinnamon Remix distribution has become an official Ubuntu flavor and will join the rest of the flavors starting with the upcoming Ubuntu 23.04 (Lunar Lobster) release. Created and maintained by members of the Linux community, Ubuntu Cinnamon Remix is an Ubuntu derivative that features the modern Cinnamon desktop environment developed by the Linux Mint team. Cinnamon Remix aims to offer a traditional approach to the modern Linux desktop. Until now, the maintainers of Ubuntu Cinnamon Remix did a very good job keeping up with all upstream Ubuntu releases, even offering a custom version of the official wallpaper of each new Ubuntu release to match the Cinnamon desktop environment's style. Ubuntu Cinnamon will not be the only new official Ubuntu flavor this Spring when Ubuntu 23.04 will be released as the maintainers of Ubuntu Unity have also managed to obtain official Ubuntu flavor status last year in September. As with Ubuntu Unity, the next step now for the Ubuntu Cinnamon maintainers is to bake daily ISO images in preparation for the upcoming Lunar Lobster release and maybe even take part in the Ubuntu 23.04 beta release later this week on March 30th.

Arduino Announces 'UNO R4' with Clock Speed/Memory/Storage Upgrades, 32-bit ARM Cortex-M4
by Peter Reutemann 28 Mar '23

28 Mar '23

'Saturday Arduino announced "a new, revolutionary revision of the iconic UNO board," promising "a long-awaited update on performance and possibilities." The Arduino UNO R4 indeed preserves the well-known features of the UNO family — standard form factor, shield compatibility, 5V operating voltage, outstanding robustness — while offering no less than a 32-bit Cortex-M4 and a 3-to-16x increase in clock speed, memory and flash storage.... The UNO R4 will come in two versions — UNO R4 WiFi and UNO R4 Minima — offering unprecedented performance and possibilities for the maker community. The WiFi version comes with an Espressif S3 WiFi module, expanding creative opportunities for makers, educators, and hobbyists alike; while the UNO R4 Minima provides a cost-effective option for those seeking the new microcontroller without additional features.... SRAM went from 2kB to 32kB, and flash memory went from 32kB to 256kB to accommodate more complex projects. In addition, following the requests from the community, the USB port was upgraded to the USB-C and maximum power supply voltage was increased to 24V with an improved thermal design. The board provides a CAN bus, which allows users to minimize wiring and execute different tasks in parallel by connecting multiple shields. Finally, the new board includes a 12-bit analog DAC. All in all, Arduino UNO R4 is the answer to the requests for improvement and updates the developer and maker community has been advancing, making it easier than ever to get started with Arduino.... On the software side, a big effort is being made to maximize retrocompatibility of the most popular Arduino libraries so that users will be able to rely on existing code examples and tutorials.' -- source: https://hardware.slashdot.org/story/23/03/26/2357240 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/

Pinduoduo App Malware Detailed By Cybersecurity Researchers
by Peter Reutemann 28 Mar '23

28 Mar '23

'Security researchers at Moscow-based Kaspersky Lab have identified and outlined potential malware in versions of PDD Holdings' Chinese shopping app Pinduoduo, days after Google suspended it from its Android app store. From a report: In one of the first public accountings of the malicious code, Kaspersky laid out how the app could elevate its own privileges to undermine user privacy and data security. It tested versions of the app distributed through a local app store in China, where Huawei Technologies, Tencent Holdings and Xiaomi run some of the biggest app markets. Kaspersky's findings, shared with Bloomberg News, were among the clearest explanations from an independent security team for what triggered Google's action and malware warning last week. The cybersecurity firm, which has played a role in uncovering some of the biggest cyberattacks in history, said it found evidence that earlier versions of Pinduoduo exploited system software vulnerabilities to install backdoors and gain unauthorized access to user data and notifications. Those conclusions agreed in large part with those of researchers that had posted their discoveries online in past weeks, though Bloomberg News hasn't verified the authenticity of the earlier reports.' -- source: https://it.slashdot.org/story/23/03/27/1420241 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 Orange Pi 5: a Fast Alternative To The Raspberry Pi 4
by Peter Reutemann 27 Mar '23

27 Mar '23

'"With an 8-core Rockchip RK3588S SoC, the Orange Pi 5 is leaps and bounds faster than the aging Raspberry Pi 4," writes Phoronix: With up to 32GB of RAM, the Orange Pi 5 is also capable of serving for a more diverse user-base and even has enough potential for assembling a budget Arm Linux developer desktop. I've been testing out the Orange Pi 5 the past few weeks and it's quite fast and nice for its low price point. The Orange Pi 5 single board computer was announced last year and went up for pre-ordering at the end of 2022.... When it comes to the software support, among the officially available options for the Orange Pi 5 are Orange Pi OS, Ubuntu, Debian, Android, and Armbian. Other ARM Linux distributions will surely see varying levels of support while even the readily available ISO selection offered by Orange Pi is off to a great start.... Granted, the Orange Pi developer community isn't as large as that of the Raspberry Pi community or the current range of accessories and documentation, but for those more concerned about features and performance, the Orange Pi 5 is extremely interesting. The article includes Orange Pi 5 specs: - A 26-pin header - HDMI 2.1, Gigabit LAN, M.2 PCIe 2.0, and USB3 connectivity - A Mali G510 MP4 graphics processor, "which has open-source driver hope via the Panfrost driver stack." - Four different versions with 4GB, 8GB, 16GB, or 32GB of RAM using LPDDR4 or LPDDR4X. "The Orange Pi 4GB retails for ~$88, the Orange Pi 5 8GB version retails for $108, and the Orange Pi 5 16GB version retails for $138, while as of writing the 32GB version wasn't in stock." In 169 performance benchmarks (compared to Raspberry Pi 4 boards), "this single board computer came out to delivering 2.85x the performance of the Raspberry Pi 400 overall." And through all this the average SoC temperature was 71 degrees with a peak of 85 degrees — without any extra heatsink or cooling.' -- source: https://build.slashdot.org/story/23/03/25/1725257 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 Pixel Bug Lets You 'Uncrop' the Last Four Years of Screenshots
by Peter Reutemann 25 Mar '23

25 Mar '23

'Ars Technica: Back in 2018, Pixel phones gained a built-in screenshot editor called "Markup" with the release of Android 9.0 Pie. The tool pops up whenever you take a screenshot, and tapping the app's pen icon gives you access to tools like crop and a few colored drawing pens. That's very handy assuming Google's Markup tool actually does what it says, but a new vulnerability points out the edits made by this tool weren't actually destructive! It's possible to uncrop or unredact Pixel screenshots taken during the past four years. The bug was discovered by Simon Aarons and is dubbed "Acropalypse," or more formally CVE-2023-21036. There's a proof-of-concept app that can unredact Pixel screenshots at acropalypse.app, and it works! There's also a good technical write-up here by Aarons' collaborator, David Buchanan. The basic gist of the problem is that Google's screenshot editor overwrites the original screenshot file with your new edited screenshot, but it does not truncate or recompress that file in any way. If your edited screenshot has a smaller file size than the original -- that's very easy to do with the crop tool -- you end up with a PNG with a bunch of hidden junk data at the end of it. That junk data is made up of the end bits of your original screenshot, and it's actually possible to recover that data. While the bug was fixed in the March 2023 security update for Pixel devices, it doesn't solve the problem, notes Ars. "There's still the matter of the last four years of Pixel screenshots that are out there and possibly full of hidden data that people didn't realize they were sharing."' -- source: https://it.slashdot.org/story/23/03/20/2034220 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/

23 Mar '23

Amid all the various AI-related titbits in this article <https://www.theregister.com/2023/03/21/google_bard_ai/> is a link to a Twitter thread where someone asked Google Bard (Google’s answer to ChatGPT) to predict when it is likely to join the ever-growing list of dead Google projects. And it said it is already dead <https://twitter.com/juanbuis/status/1638289186351456257>, and even gave detailed reasons why it was a failure, including lack of user adoption, lack of innovation and lack of resources. Seems the AI managed to pick up a posting on YCombinator predicting it would be shut down in a year’s time, and somehow interpreted it as a news item referring to the present time.

23 Mar '23

'"9to5Linux.com reports that the GNOME 44 desktop environment is officially released and gives a detailed look at the major new features and improvements," writes Slashdot reader prisoninmate. From the report: Code-named "Kuala Lumpur" in recognition of the work done by the organizers of GNOME.Asia Summit 2022 conference, GNOME 44 introduces a GTK4 port of the Epihaphy (GNOME Web) web browser, a file chooser grid view for apps that use the standard GTK file chooser, as well as support for adding a WireGuard VPN directly from the Network panel. GNOME 44 continues to improve the Quick Settings feature introduced in GNOME 43 by implementing a submenu to the Bluetooth button to more easily and quickly connect or disconnect peripherals, adding descriptions to buttons to easily see their status, and implementing a new feature called Background Apps via a new background monitoring service in XDG portals 1.16.0." A full list of changes are available in the official release notes. The GNOME project also published a launch video on YouTube.' -- source: https://tech.slashdot.org/story/23/03/22/2211217 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 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

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/

01 Mar '23

Hi everyone The second attempt at running our AGM took place successfully on Monday night and the minutes are now available: http://wiki.wlug.org.nz/MeetingTopics.2023-02-27 Due to no one stepping forward to take up the president's office, we've decided to wind up the society. Thanks everyone for supporting WLUG over the years. We will keep this mailing list open as a place for exchanging news and knowledge around Linux and open source software. 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/
