Firefox Gets Privacy Boost By Disabling Proximity and Ambient Light Sensor APIs
by Peter Reutemann 12 Mar '18

12 Mar '18

'Stating with Firefox 60 -- expected to be released in May 2018 -- websites won't be able to use Firefox to access data from sensors that provide proximity distances and ambient light information. >From a report: Firefox was allowing websites to access this data via the W3C Proximity and Ambient Light APIs. But at the start of the month, Mozilla engineers decided to disable access to these two APIs by default. The APIs won't be removed, but their status is now controlled by two Firefox flags that will ship disabled by default. This means users will have to manually enable the two flags before any website can use Firefox to extract proximity and ambient light data from the device's underlying sensors. The two flags will be available in Firefox's about:config settings page. The screenshot below shows the latest Firefox Nightly version, where the two flags are now disabled, while other sensor APIs are enabled.' -- source: https://news.slashdot.org/story/18/03/12/1641205 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft Helps Get A Computer Recycler Sentenced To 15 Months In Prison For Offering Unapproved Recovery Disks
by Lawrence D'Oliveiro 12 Mar '18

12 Mar '18

<https://www.techdirt.com/articles/20180223/17294539295/microsoft-helps-get-…>: Someone dedicates his life to keeping landfills free of harmful material and the government wants to send him to prison. And it's all based on Microsoft's assertion it would have sold as many recovery disks as Lundgren created if only Lundgren hadn't created them. Ignored is the fact they never were distributed. Also ignored is the dubiousness of "lost sales" assertions, which are always 100% conjecture and always presented as a simplistic equation: "1 Piracy = 1 Lost Sale." But in this case, no sales were lost because no sales were replaced with bootleg boot disks. And "sales" must be a legal term of art. Microsoft allows anyone to download a recovery disk for free. But in court, these are suddenly worth money because infringement. To ensure someone gets tossed in jail for breaking the chain of planned obsolescence, Microsoft (and prosecutors) want the court to believe the existence of recovery disks that do nothing unless a person already has a licensed copy of Windows has somehow made the company $700,000 poorer. Given the limitations of burned recovery disks, it's impossible to see where infringement even comes into play. And yet here we are, watching prosecutorial discretion morph into putting someone's head on a platter over recovery disks any one of us could download hundreds of times from Microsoft's website without a single murmur about "lost sales" from the tech giant.

SgxSpectre Attack Can Extract Data From Intel SGX Enclaves
by Peter Reutemann 11 Mar '18

11 Mar '18

'A new variation of the Spectre attack has been revealed this week by six scientists from the Ohio State University. Named SgxSpectre, researchers say this attack can extract information from Intel SGX enclaves. Intel Software Guard eXtensions (SGX) is a feature of modern Intel processors that allow an application to create so-called enclaves. This enclave is a hardware-isolated section of the CPU's processing memory where applications can run operations that deal with extremely sensitive details, such as encryption keys, passwords, user data, and more... Neither Meltdown and Spectre were able to extract data from SGX enclaves. This is where SgxSpectre comes in. According to researchers, SgxSpectre works because of specific code patterns in software libraries that allow developers to implement SGX support into their apps. Vulnerable SGX development kits include the Intel SGX SDK, Rust-SGX, and Graphene-SGX. Academics say an attacker can leverage the repetitive code execution patterns that these SDKs introduce in SGX enclaves and watch for small variations of cache size. This allows for side-channel attacks that allow a threat actor to infer and slowly recover data from secure enclaves. Intel's recent Spectre patches don't necessarily help, as an attacker can work around these fixes. Intel says an update for the Intel SGX SDK that adds SgxSpectre mitigations will be released on March 16. Apps that implement Google's Retpoline anti-Spectre coding techniques are safe, researchers say.' -- source: https://it.slashdot.org/story/18/03/10/0446211 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Developer McHardy Drops GPLv2 'Shake Down' Case
by Peter Reutemann 11 Mar '18

11 Mar '18

'Former Linux developer Patrick McHardy dropped his Gnu General Public License version 2 (GPLv2) violation case against Geniatech in a German court this week. ZDNet explains why some consider this a big "win": People who find violations typically turn to organizations such as the Free Software Foundation, Software Freedom Conservancy (SFC), and the Software Freedom Law Center to approach violators. These organizations then try to convince violating companies to mend their ways and honor their GPLv2 legal requirements. Only as a last resort do they take companies to court to force them into compliance with the GPLv2. Patrick McHardy, however, after talking with SFC, dropped out from this diplomatic approach and has gone on his own way. Specifically, McHardy has been accused of seeking his own financial gain by approaching numerous companies in German courts. Geniatech claimed McHardy has sued companies for Linux GPLv2 violations in over 38 cases. In one, he'd requested a contractual penalty of €1.8 million. The company also claimed McHardy had already received over €2 million from his actions... In July 2016, the Netfilter developers suspended him from the core team. They received numerous allegations that he had been shaking down companies. McHardy refused to discuss these issues with them, and he refused to sign off on the Principles of Community-Oriented GPL Enforcement. In October 2017, Greg Kroah-Hartman, Linux kernel maintainer for the stable branch, summed up the Linux kernel developers' position. Kroah-Hartman wrote: "McHardy has sought to enforce his copyright claims in secret and for large sums of money by threatening or engaging in litigation...." Had McHardy continued on his way, companies would have been more reluctant to use Linux code in their products for fear that a single, unprincipled developer could sue them and demand payment for his copyrighted contributions... McHardy now has to bear all legal costs for both sides of the case. In other words, when McHardy was faced with serious and costly opposition for the first time, he waved a white flag rather than face near certain defeat in the courts.

Hardcoded Password Found in Cisco Software
by Peter Reutemann 08 Mar '18

08 Mar '18

'Cisco released 22 security advisories yesterday, including two alerts for critical fixes, one of them for a hardcoded password that can give attackers full control over a vulnerable system. From a report: The hardcoded password issue affects Cisco's Prime Collaboration Provisioning (PCP), a software application that can be used for the remote installation and maintenance of other Cisco voice and video products. Cisco PCP is often installed on Linux servers. Cisco says that an attacker could exploit this vulnerability (CVE-2018-0141) by connecting to the affected system via Secure Shell (SSH) using the hardcoded password. The flaw can be exploited only by local attackers, and it also grants access to a low-privileged user account. In spite of this, Cisco has classified the issue as "critical." Although this vulnerability has a Common Vulnerability Scoring System (CVSS) Base score of 5.9, which is normally assigned a Security Impact Rating (SIR) of Medium, there are extenuating circumstances that allow an attacker to elevate privileges to root. For these reasons, the SIR has been set to Critical.' -- source: https://it.slashdot.org/story/18/03/08/145209 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Disabling Super-Key App-Menu Shortcut In KDE
by Lawrence D'Oliveiro 07 Mar '18

07 Mar '18

Another new “feature” that KDE has acquired in the last few months is that you just have to press and release the Super (aka “Windows”†) modifier key, and the application menu will appear. This annoys me because I frequently lean on modifier keys while thinking about whether to use them, then release them when I change my mind. And then this damn menu pops up. As is usual with KDE, turning this off is pretty easy, but in this case it’s a little counterintuitive. If you right-click on the app-menu icon in the taskbar, you can choose the “Application Launcher Settings” item in the menu that appears (the name might vary a little bit depending on which particular app menu widget you have installed). In the settings dialog that comes up, you will see two panes to choose from, “Appearance” and “Keyboard shortcuts”. Naturally you go to “Keyboard shortcuts”, only to see an entry showing Alt-F1 as the trigger keystroke. So where do you control the use of the Super key? Never fear. Remove this Alt-F1 setting, and the special behaviour of the Super key disappears as well. †No, it doesn’t have a Windows logo on my Das Keyboard Pro 4. It’s imprinted with some kind of indescribable wing-like symbol.

Ask Slashdot: Should We Worry Microsoft Will 'Embrace, Extend, and Extinguish' Linux?
by Peter Reutemann 07 Mar '18

07 Mar '18

'While there is no proof that anything nefarious is afoot, it does feel like maybe the Windows-maker is hijacking the Linux movement a bit by serving distros in its store. I hope there is no "embrace, extend, and extinguish" shenanigans going on. Just yesterday, we reported that Kali Linux was in the Microsoft Store for Windows 10. That was big news, but it was not particularly significant in the grand scheme, as Kali is not very well known. Today, there is some undeniably huge news -- Debian is joining SUSE, Ubuntu, and Kali in the Microsoft Store. Should the Linux community be worried? My concern lately is that Microsoft could eventually try to make the concept of running a Linux distro natively a thing of the past. Whether or not that is the company's intention is unknown. The Windows maker gives no reason to suspect evil plans, other than past negative comments about Linux and open source. For instance, former Microsoft CEO Steve Ballmer once called Linux "cancer" -- seriously.' -- source: https://tech.slashdot.org/story/18/03/07/159249 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

From <http://www.theregister.co.uk/2018/03/07/mod_spends_more_computers_than_weap…>: Spending on weapons and ammunition for the Armed Forces totalled £1.15bn in fiscal year 2016/17, whereas the MoD spent £1.45bn on computer services in the same period. For the four prior years, spending on computers consistently outpaced that for arms and ammo, with half a billion more being spent on computers than weapons in 2015/16. ... Only shipbuilding and repairing, aircraft and spacecraft, and "technical and financial services" spending outpaced the MoD's expenditure on computers. Even construction, at £1.20bn, lagged behind it.

Turning Off Software Update Notifications In KDE
by Lawrence D'Oliveiro 06 Mar '18

06 Mar '18

Seems the latest version of KDE includes an automatic notifier when there are system updates available. This is great for, shall we say, “normal” users. But I run Debian Unstable. Which means I will be nagged for more updates within a matter of hours after doing a system upgrade, and things will rapidly go downhill from there. So naturally I would rather turn these off completely. The obvious place to find this setting would be in the “Notifications” panel in the System Settings. Unfortunately, the “Event source:” menu lists about three dozen different sources of notification events, and it isn’t obvious (at least, it wasn’t to me) which one handles software updates. The answer is, it’s the one called “Discover”. You will see only one event in its list: “Updates Are Available”. Simply uncheck all the forms of notification for this event. Hmm, I wonder if this panel couldn’t do with a search box...?

No Safe Haven For Victims Of Digital Abuse
by Lawrence D'Oliveiro 05 Mar '18

05 Mar '18

Blocking messages from online abusers -- and even changing your identity to get away from them -- may work fine against someone on the other side of the world. But what if the abuser is your close partner? <https://slate.com/technology/2018/03/apps-cant-stop-exes-who-use-technology…>: When you learn that your privacy has been compromised, the common advice is to prevent additional access—delete your insecure account, open a new one, change your password. But in abusive romantic relationships, disconnection can be extremely fraught. For one, it can put the victim at risk of physical harm: If abusers expect digital access and that access is suddenly closed off, it can lead them to become more violent or intrusive in other ways. It may seem cathartic to delete abusive material, like alarming text messages—but if you don’t preserve that kind of evidence, it can make prosecution more difficult. And closing some kinds of accounts, like social networks, to hide from a determined abuser can cut off social support that survivors desperately need.

Libre Content Creation: 2018 In Perspective
by Lawrence D'Oliveiro 05 Mar '18

05 Mar '18

Nice roundup <http://libregraphicsworld.org/blog/entry/2018-in-perspective> from Alexandre Prokoudine on where a bunch of Free graphics/audio/video projects have gone and where they are likely to go over the coming year. Gimp 2.10 continues to be delayed, but in return the list of goodies promised continues to lengthen: The team initially intended v2.10 to be more or less a GEGL-based upgrade of v2.8 plus high bit depth precision support. Needless to say, the plan hasn't exactly worked: there will be a lot more than that. In fact, even now, when only critical bugs are supposed to be worked on, the team cannot resist making improvements that aren't blocking the release. Another interesting one is an initiative in Germany to come up with a nonproprietary alternative to common colour specifications like Pantone: In December 2017, FreieFarbe e.V. announced that their initiative for „Open Colour Communication“ standard was supported by DIN and will become a DIN SPEC (which is the first step towards DIN Norm). It is claimed that DIN intends to turn this into an international standard via ISO later. The FreieFarbe / FreeColour initiative aims to provide an open alternative to Pantone, HKS, and other proprietary colour systems. They argue that unlike Pantone and some other proprietary manufacturers like RAL, FreiFarbe has an actual color system. On the music-production front, Zyn-Fusion seems to be developing as the successor to the venerable ZynAddSubFX, while VCV Rack is the candidate for the ultimate software modular synth, complete with rat’s nest of (virtual) connecting wires. (I’ve seen a demo or two on YouTube.)

OpenBSD Releases Meltdown Patch

'OpenBSD's Meltdown patch has landed, in the form of a Version 11 code update that separates user memory pages from the kernel's -- pretty much the same approach as was taken in the Linux kernel. From a report: A few days after the Meltdown/Spectre bugs emerged in January, OpenBSD's Phillip Guenther responded to user concerns with a post saying the operating system's developers were working out what to do. Now he's revealed the approach used to fix the free OS: "When a syscall, trap, or interrupt takes a CPU from userspace to kernel the trampoline code switches page tables, switches stacks to the thread's real kernel stack, then copies over the necessary bits from the trampoline stack. On return to userspace the opposite occurs: recreate the iretq frame on the trampoline stack, switch stack, switch page tables, and return to userspace." That explanation is somewhat obscure to non-developers, but there's a more readable discussion of what the project's developers had in mind from January, here.' -- source: https://it.slashdot.org/story/18/02/23/1519245 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

uTorrent Client Affected by Some Pretty Severe Security Flaws

From the report: The vulnerabilities have been discovered by Google Project Zero security researcher Tavis Ormandy, and they impact uTorrent Web, a new web-based version of the uTorrent BitTorrent client, and uTorrent Classic, the old uTorrent client that most people know. Ormandy says that both uTorrent clients are exposing an RPC server -- on port 10000 (uTorrent Classic) and 19575 (uTorrent Web). The expert says that attackers can hide commands inside web pages that interact with this open RPC server. The attacker only needs to trick a user with a vulnerable uTorrent client to access a malicious web page. Furthermore, the uTorrent clients are also vulnerable to DNS rebinding -- a vulnerability that allows the attacker to legitimize his requests to the RPC server.' -- source: https://it.slashdot.org/story/18/02/21/180206 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

by Peter Reutemann 20 Feb '18

20 Feb '18

'In this article, we will walk through the process of getting started with WSL on your Windows 10 machine. You must be running the latest version of Windows 10 with Fall Creator Update installed. Then, check which version of Windows 10 is installed on your system by searching on “About” in the search box of the Start menu. You should be running version 1709 or the latest to use WSL. If an older version is installed, you need to download and install the Windows 10 Fall Creator Update (FCU) from this page. Once FCU is installed, go to Update Settings (just search for “updates” in the search box of the Start menu) and install any available updates.' -- source: https://www.linux.com/blog/learn/2018/2/how-get-started-using-wsl-windows-10 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

cron Is Becoming Obsolete
by Lawrence D'Oliveiro 20 Feb '18

20 Feb '18

I have to get out of the habit of (only) checking various /etc/cron* locations for periodic system tasks. Debian is making more and more use of systemd timer tasks. The nice thing is, you can see them all with a simple command: systemctl status \*.timer Got caught out with this on a client’s machine the other day: when you install the certbot package (for managing certificates issued by Let’s Encrypt) on Debian, it also automatically adds a systemd timer to run certificate renewals twice a day, you don’t need to set up your own cron task to manage this.

Chrome Extension Brings 'View Image' Button Back
by Peter Reutemann 19 Feb '18

19 Feb '18

'Google recently removed the convenient "view image" button from its search results as a result of a lawsuit with stock-photo agency Getty. Thankfully, one day later, a developer created an extension that brings it back. 9to5Google reports: It's unfortunate to see that button gone, but an easy to use Chrome extension brings it back. Simply install the extension from the Chrome Web Store, and then any time you view an image on Google Image Search, you'll be able to open that source image. You can see the functionality in action in the video below. The only difference we can see with this extension versus the original functionality is that instead of opening the image on the same page, it opens it in a new tab. The extension is free, and it will work with Chrome for Windows, Mac, Chrome OS, or anywhere else the full version of Chrome can be used. 9to5Google has a separate post with step-by-step instructions to get the Google Images "view image" button back.' -- source: https://tech.slashdot.org/story/18/02/19/0334208 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Skype Can't Fix a Nasty Security Bug Without a Massive Code Rewrite
by Peter Reutemann 15 Feb '18

15 Feb '18

'ZDNet reports of a security flaw in Skype's updater process that "can allow an attacker to gain system-level privileges to a vulnerable computer." If the bug is exploited, it "can escalate a local unprivileged user to the full 'system' level rights -- granting them access to every corner of the operating system." What's worse is that Microsoft, which owns Skype, won't fix the flaw because it would require the updater to go through "a large code revision." Instead, Microsoft is putting all its resources on building an altogether new client. From the report: Security researcher Stefan Kanthak found that the Skype update installer could be exploited with a DLL hijacking technique, which allows an attacker to trick an application into drawing malicious code instead of the correct library. An attacker can download a malicious DLL into a user-accessible temporary folder and rename it to an existing DLL that can be modified by an unprivileged user, like UXTheme.dll. The bug works because the malicious DLL is found first when the app searches for the DLL it needs. Once installed, Skype uses its own built-in updater to keep the software up to date. When that updater runs, it uses another executable file to run the update, which is vulnerable to the hijacking. The attack reads on the clunky side, but Kanthak told ZDNet in an email that the attack could be easily weaponized. He explained, providing two command line examples, how a script or malware could remotely transfer a malicious DLL into that temporary folder.

Ubuntu Wants To Collect Data About Your System -- Starting With 18.04 LTS
by Peter Reutemann 15 Feb '18

15 Feb '18

' In an announcement on Ubuntu mailing list, Will Cooke, on behalf of the Ubuntu Desktop team, announced Canonical's plans to collect some data related to the users' system configuration and the packages installed on their machines. From a report: Before you read anything further, it's important to note that users will have the option to opt-out of this data collection. The company plans to add a checkbox to the installer, which would be checked by default. The option could be like: "Send diagnostics information to help improve Ubuntu." As per your convenience, you can opt-out during the installation. An option to do the same will also be made available in the Privacy panel of GNOME Settings. With this data collection, the team wishes to improve the daily experiences of the Ubuntu users. It's worth noting that the collected data will be sent over encrypted connections and no IP addresses will be tracked. To be precise, the collected data will include: flavour and version of Ubuntu, network connectivity or not, CPU family, RAM, disk(s) size, screen(s) resolution, GPU vendor and model, OEM manufacturer, location (based on the location selection made during install), no IP information, time taken for Installation, auto-login enabled or not, disk layout selected, third party software selected or not, download updates during install or not, livePatch enabled or not.' -- source: https://news.slashdot.org/story/18/02/15/1410203 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Critical Telegram flaw under attack disguised malware as benign images
by Peter Reutemann 14 Feb '18

14 Feb '18

'Makers of the Telegram instant messenger have fixed a critical vulnerability that hackers were actively exploiting to install malware on users' computers, researchers said Tuesday. The flaw, which resided in the Windows version of the messaging app, allowed attackers to disguise the names of attached files, researchers from security firm Kaspersky Lab said in a blog post. By using the text-formatting standard known as Unicode, attackers were able to cause characters in file names to appear from right to left, instead of the left-to-right order that's normal for most Western languages.' -- source: https://arstechnica.com/information-technology/2018/02/telegram-app-purged-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft’s compiler-level Spectre fix shows how hard this problem will be to solve
by Peter Reutemann 14 Feb '18

14 Feb '18

'The Meltdown and Spectre attacks that use processor speculative execution to leak sensitive information have resulted in a wide range of software changes to try to limit the scope for harm. Many of these are operating system-level fixes, some of which depend on processor microcode updates. But Spectre isn't a simple attack to solve; operating system changes help a great deal, but application-level changes are also needed. Apple has talked about some of the updates it has made to the WebKit rendering engine, used in its Safari browser, but this is only a single application. Microsoft is offering a compiler-level change for Spectre. The "Spectre" label actually covers two different attacks. The one that Microsoft's compiler is addressing, known as "variant 1," concerns checking the size of an array: before accessing the Nth element of an array, code should check that the array has at least N elements in it. Programmers using languages like C and C++ often have to write these checks explicitly. Other languages, like JavaScript and Java, perform them automatically. Either way, the test has to be done; attempts to access array members that don't exist are a whole class of bugs all on their own. [...] In fairness, Microsoft does warn that "there is no guarantee that all possible instances of variant 1 will be instrumented," but as Kocher's examination shows, it's not simply that some Spectre-vulnerable code will escape the compiler's fixes. Much—and perhaps even most—Spectre-vulnerable code will escape. And even if it were only a few instances, bad guys would be able to locate the unprotected routines and focus their attacks accordingly.' -- source: https://arstechnica.com/gadgets/2018/02/microsofts-compiler-level-spectre-f… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

The Most Popular Linux Desktop Programs
by Peter Reutemann 14 Feb '18

14 Feb '18

'The most recent Linux Questions poll results are in. Steven J. Vaughan-Nichols, writing for ZDNet: LinuxQuestions, one of the largest internet Linux groups with 550,000 members, has just posted the results from its latest survey of desktop Linux users. In the always hotly-contested Linux desktop environment survey, the winner was the KDE Plasma Desktop. It was followed by the popular lightweight Xfce, Cinnamon, and GNOME. If you want to buy a computer with pre-installed Linux, the Linux Questions crew's favorite vendor by far was System76. Numerous other computer companies offer Linux on their PCs. These include both big names like Dell and dedicated small Linux shops such as ZaReason, Penguin Computing, and Emperor Linux. Many first choices weren't too surprising. For example, Linux users have long stayed loyal to the Firefox web browser, and they're still big fans. Firefox beat out Google Chrome by a five-to-one margin. And, as always, the VLC media player is far more popular than any other Linux media player. For email clients, Mozilla Thunderbird remains on top. That's a bit surprising given how Thunderbird's development has been stuck in neutral for some time now. When it comes to text editors, I was pleased to see vim -- my personal favorite -- win out over its perpetual rival, Emacs. In fact, nano and Kate both came ahead of Emacs.' -- source: https://linux.slashdot.org/story/18/02/13/1652238 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Active Browser Tabs Vs Active Browser Windows
by Lawrence D'Oliveiro 14 Feb '18

14 Feb '18

I have noticed some interesting behaviour with video playback on various websites, at least with Firefox. Videos on the NZ Herald website, for example, don’t start playing until the tab becomes the active one in the window. Also on YouTube, sometimes after an ad, there is a display inviting you to take part in some kind of survey. This displays for a fixed amount of time, but that time only accumulates while the tab is active -- make it inactive, and the time counter stops until it becomes active again. *But* ... the active tab is still considered to be active even if the window is not the frontmost one. This means if you want to do something else while waiting for a YouTube ad to finish playing (with the sound off, of course) and the extra display to disappear, you just have to do it in an entirely separate window.

Facebook is Pushing Its Data-tracking Onavo VPN Within Its Main Mobile App
by Peter Reutemann 14 Feb '18

14 Feb '18

'Onavo Protect, the VPN client from the data-security app maker acquired by Facebook back in 2013, has now popped up in the Facebook app itself, under the banner "Protect" in the navigation menu. Clicking through on "Protect" will redirect Facebook users to the "Onavo Protect -- VPN Security" app's listing on the App Store. We're currently seeing this option on iOS only, which may indicate it's more of a test than a full rollout here in the U.S. Marketing Onavo within Facebook itself could lead to a boost in users for the VPN app, which promises to warn users of malicious websites and keep information secure as you browse. But Facebook didn't buy Onavo for its security protections. Instead, Onavo's VPN allow Facebook to monitor user activity across apps, giving Facebook a big advantage in terms of spotting new trends across the larger mobile ecosystem. For example, Facebook gets an early heads up about apps that are becoming breakout hits; it can tell which are seeing slowing user growth; it sees which apps' new features appear to be resonating with their users, and much more. Further reading: Do Not, I Repeat, Do Not Download Onavo, Facebook's Vampiric VPN Service (Gizmodo).' -- source: https://tech.slashdot.org/story/18/02/13/2026211 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Camera Makers Still Showing Zero Interest In Protecting Users With Built-In Encryption

13 Feb '18

From <https://www.techdirt.com/articles/20180204/07404639150/camera-makers-still-…>: The Freedom of the Press Foundation sent a letter to major camera manufacturers in December 2016, letting them know filmmakers and journalists would appreciate a little assistance keeping their data out of governments' hands. ... We've covered many cases where police officers have seized phones/cameras and deleted footage captured by bystanders. ... Unfortunately, it doesn't look like camera manufacturers are considering offering encryption. The issue still doesn't even appear to be on their radar, more than a year after the Freedom of the Press Foundation's letter -- signed by 150 photographers and filmmakers -- indicated plenty of customers wanted better protection for their cameras. ... If a government can search something, it will. Encryption may not thwart all searches, but it will at least impede the most questionable ones.

Hi everyone At the last meeting, Ian suggested to have cryptocurrencies (https://en.wikipedia.org/wiki/Cryptocurrency) as topic for our meeting next month. One aspect is the increasing amount of power that is consumed in order to mine "coins". The other interesting aspect introduced by, but not limit to, cryptocurrencies is the concept of the blockchain (https://en.wikipedia.org/wiki/Blockchain) an open, distributed ledger of transactions. Is there interest? Any volunteers to talk about something regarding this topic (history, current status, etc)?

VideoLAN VLC releases version 3.0 with HDR and 360-degree video

'The popular cross-platform, open-source video player VLC has received a significant update in 3.0, the first in what will be called the Vetinari branch.

While VLC is open source, this part of it isn't; Tom's Hardware reports that VideoLAN explained it "used Google’s official closed-source SDK to build out the feature, which prevents it from releasing the source." [*] Other major added features include 3D audio support, audio passthrough for HD audio codecs, and support for browsing NAS drives. As always, a bunch of new codecs are supported too.' [*] 'Please note that Chromecast support in VLC 3.0 is fully open-source for all platforms! That’s the reason why it took us so long to ship as we completely reverse-engineered the entire thing. The closed-source component by Google can’t be used for legal reasons in VLC, isn’t compatible with Macs, Linux and Windows and supports a very limited set of codecs only. With our code, you can play basically anything VLC can decode on your Chromecast (as we transcode on-the-fly if needed).' -- source: https://arstechnica.com/gadgets/2018/02/videolan-vlc-releases-version-3-0-w… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'Razer Doesn't Care About Linux'
by Peter Reutemann 12 Feb '18

'Razer is a vendor that makes high-end gaming hardware, including laptops, keyboards and mice. I opened a ticket with Razor a few days ago asking them if they wanted to support the LVFS project by uploading firmware and sharing the firmware update protocol used. I offered to upstream any example code they could share under a free license, or to write the code from scratch given enough specifications to do so. This is something I've done for other vendors, and doesn't take long as most vendor firmware updaters all do the same kind of thing; there are only so many ways to send a few kb of data to USB devices. The fwupd project provides high-level code for accessing USB devices, so yet-another-update-protocol is no big deal. I explained all about the LVFS, and the benefits it provided to a userbase that is normally happy to vote using their wallet to get hardware that's supported on the OS of their choice. I just received this note on the ticket, which was escalated appropriately: "I have discussed your offer with the dedicated team and we are thankful for your enthusiasm and for your good idea. I am afraid I have also to let you know that at this moment in time our support for software is only focused on Windows and Mac."

How the First Open Source Software and Hardware Satellite UPSat Was Built
by Peter Reutemann 11 Feb '18

11 Feb '18

'UPSat is the first open source -- both hardware and software -- satellite to have ever been launched in orbit. Pierros Papadeas, the Director of Operations for Libre Space Foundation, which helped build the UPSat, talked about the project at FOSDEM, a non-commercial, volunteer-organized European event focused on free and open-source software development. You can watch the talk here; and read an interview of him with folks at FOSDEM ahead of the talk here. Two excerpts from the interview: Q: What challenges did you encounter while designing, building, testing and eventually launching UPSat in orbit? PP: The challenges where numerous, starting with the financial ones. Lack of appropriate funding led us to invest heavily in the project (through Libre Space Foundation funds) to ensure its successful completion. Countless volunteer participation was also key to the success. On the technical side, with minimal documentation and knowledge sharing around space projects we had to re-invent the wheel and discover many procedures and practices in a really short time-frame (6 months - unheard for a space mission). Lack of tools and equipment made our building process a creative exploration as we had to figure out ways to achieve specific tasks resorting to purpose-built projects in our local lab (hackerspace.gr). Testing and verification facilities where also a challenge mainly as we had to undergo much more extensive tests than other missions, having none of our components already "flight proven". Again creativity and countless hours of negotiations and documentation got us to the final delivery point. Launching UPSat in orbit was secured once the delivery happened, but as any typical space mission it came with long delays and timeline push-backs. Q: What do you hope to accomplish by giving this talk? What do you expect? Through this talk we would like to raise awareness for open source initiatives in space, and inspire open source technologists (engineers, programmers, analysts, makers) to engage in an open source project. We would also love to gather feedback and ideas on next steps and provide contribution opportunities for interested parties.' -- source: https://news.slashdot.org/story/18/02/11/2139203 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

EFF Founder John Perry Barlow Has Died At Age 70
by Peter Reutemann 08 Feb '18

08 Feb '18

'The Electronic Frontier Foundation reports that its founder, John Perry Barlow, has passed away quietly in his sleep this morning. He was 70 years old. From the report: It is no exaggeration to say that major parts of the Internet we all know and love today exist and thrive because of Barlow's vision and leadership. He always saw the Internet as a fundamental place of freedom, where voices long silenced can find an audience and people can connect with others regardless of physical distance. Barlow was sometimes held up as a straw man for a kind of naive techno-utopianism that believed that the Internet could solve all of humanity's problems without causing any more. As someone who spent the past 27 years working with him at EFF, I can say that nothing could be further from the truth. Barlow knew that new technology could create and empower evil as much as it could create and empower good. He made a conscious decision to focus on the latter: "I knew it's also true that a good way to invent the future is to predict it. So I predicted Utopia, hoping to give Liberty a running start before the laws of Moore and Metcalfe delivered up what Ed Snowden now correctly calls 'turn-key totalitarianism.'" Barlow's lasting legacy is that he devoted his life to making the Internet into "a world that all may enter without privilege or prejudice accorded by race, economic power, military force, or station of birth... a world where anyone, anywhere may express his or her beliefs, no matter how singular, without fear of being coerced into silence or conformity."' -- source: https://politics.slashdot.org/story/18/02/07/234213 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

New IoT botnet offers DDoSes of once-unimaginable sizes for $20
by Peter Reutemann 02 Feb '18

02 Feb '18

'Organizers of a new botnet made up of infected home and small office routers are brazenly selling denial-of-service attacks of once unimaginable volumes for just $20 per target. Calling itself Los Calvos de San Calvicie, the group is advertising several services on this site. Among the services are distributed denial-of-service attacks of 290 to 300 gigabits per second for $20 each. While a third the size of some of the biggest recorded attacks, 290Gbps is still enough to bring most sites down unless they seek DDoS mitigation services, which in many cases cost considerable amounts of money. Just five years ago, 300Gbps was considered enough volume to shut down the Internet's core infrastructure. Los Calvos de San Calvicie members have been spotted assembling a botnet in recent days that very possibly has the firepower required to deliver the potent attacks promised. According to Pascal Geenens, a researcher at security firm Radware, the group is building the botnet by exploiting two vulnerabilities: one in RealTek routers running out-of-date firmware and the other in the Huawei HG532 router, where a patch released in December has yet to be installed by many users. Both vulnerabilities are also exploited by a different Internet-of-things botnet known as Satori.' -- source: https://arstechnica.com/information-technology/2018/02/for-sale-ddoses-guar… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft Releases Skype As a Snap For Linux
by Peter Reutemann 01 Feb '18

'While Microsoft has long been viewed as an enemy of the Linux community -- and it still is by some -- the company has actually transformed into an open source champion.

By offering that program to desktop Linux users, Microsoft enables them to easily communicate with friends and family that aren't on Linux, thanks to its cross-platform support. Today, Microsoft further embraces Linux by releasing Skype as a Snap. This comes after two other very popular apps became available in Snap form -- Spotify and Slack.

LibreOffice 6.0 Released: Features Superior Microsoft Office Interoperability, OpenPGP Support
by Peter Reutemann 31 Jan '18

31 Jan '18

'LibreOffice 6.0 comes two and a half years after the LibreOffice 5.x series, and it's the biggest release of the open-source and cross-platform office suite so far. It introduces a revamped design with new table styles, improved Notebookbars, new gradients, new Elementary icons, menu and toolbar improvements, and updated motif/splash screen. LibreOffice 6.0 offers superior interoperability with Microsoft Office documents and compatibility with the EPUB3 format by allowing users to export ODT files to EPUB3. It also lets you import your AbiWord, Microsoft Publisher, PageMaker, and QuarkXPress documents and templates thanks to the implementation of a set of new open-source libraries contributed by the Document Liberation project. Many great improvements were made to the OOXML and ODF filters, as well as in the EMF+, Adobe Freehand, Microsoft Visio, Adobe Pagemaker, FictionBook, Apple Keynote, Pages, and Numbers, as well as Quattro Pro import functionality, and to the XHTML export. LibreOffice Online received numerous improvements as well in this major release of LibreOffice.' -- source: https://news.slashdot.org/story/18/01/31/1422245 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Samsung Surpasses Intel To Become the World's Largest Chipmaker
by Peter Reutemann 31 Jan '18

31 Jan '18

'Samsung Electronics just knocked Intel off its perch as the world's biggest chipmaker by revenue, a spot the U.S. company has held since 1992. From a report: On Tuesday, Samsung reported 2017 chip sales of $69 billion, blowing past Intel's $63 billion from last year. The switch underlines how Samsung has transformed itself from a maker of cheap televisions into a pervasive supplier of key components in smartphones and other modern computing devices. It's also a testament to the growth of memory chips, Samsung's main market. Intel, whose processors are the heart of about 90 percent of the world's computers, didn't have a bad year. Sales grew 6 percent. Success in computers is no longer enough, though. Memory chips, a market Intel only recently got back into, are now crucial parts of smartphones, which easily outsell PCs these days. Memory chips are also finding their way into a range of new devices such as cars. One of the ironies of Samsungâ(TM)s success in memory is that itâ(TM)s a business Intel created in the 1960s.' -- source: https://slashdot.org/story/18/01/31/1516212 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google Chrome To Feature Built-In Image Lazy Loading
by Peter Reutemann 31 Jan '18

31 Jan '18

'Future versions of Google Chrome will feature built-in support for lazy loading, a mechanism to defer the loading of images and iframes if they are not visible on the user's screen at load time. This system will first ship with Chrome for Android and Google doesn't rule out adding it to desktop versions if tests go as planned. The feature is called Blink LazyLoad, and as the name hints, it will implement the principle of "lazy loading" inside Chrome itself. Google engineers reported page load speed improvements varying from 18% to 35%, depending on the underlying network. Other browser makers have been notified of the Chrome team's plan, but none have provided input if they plan to implement a similar feature. Compared to most JS-based lazy loading scripts that only target images, Google implementation will also target iframes.' -- source: https://tech.slashdot.org/story/18/01/31/180234 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

MPEG Founder Says the MPEG Business Model Is Broken
by Peter Reutemann 30 Jan '18

30 Jan '18

'Leonardo Chiariglione, the founder and chairman of MPEG, argues on his blog that the current MPEG business model is broken. He writes, "Thanks to [MPEG's] 'business model' that can be simply described as: produce standards having the best performance as a goal, irrespective of the IPR involved. Because MPEG standards are the best in the market and have an international standard status, manufacturers/service providers get a global market of digital media products, services and applications, and end users can seamless communicate with billions of people and access millions of services. Patent holders who allow use of their patents get hefty royalties with which they can develop new technologies for the next generation of MPEG standards. A virtuous cycle everybody benefits from." But, he argues, the MPEG model is now in crisis because the forthcoming AV1 video format from the Alliance for Open Media means that "everybody realizes that the old MPEG business model is broke, all the investments (collectively hundreds of millions USD) made by the industry for the new video codec [HEVC] will go up in smoke and AOM's royalty free model will spread to other business segments as well." Chiariglione goes on to explain what can be done: "The first action is to introduce what I call 'fractional options.' ISO envisages two forms of licensing: Option 1, i.e. royalty free and Option 2, i.e. FRAND, which is taken to mean 'with undetermined license.' We could introduce fractional options in the sense that a proposer could indicate that the technology be assigned to a specifically identified profile with an 'industry license' (defined outside MPEG) that does not contain monetary values. For instance, one such license could be 'no charge' (i.e. Option 1), another could be targeted to the OTT market etc." "The second action, not meant to be alternative to the first, is to streamline the MPEG standard development process. Within this a first goal is to develop coding tools with 'clear ownership,' unlike today's tools which are often the result of contributions with possibly very different weights. A second goal is not to define profiles in MPEG. A third goal could be to embed in the standard the capability to switch coding tools on and off."' -- source: https://news.slashdot.org/story/18/01/30/0419222 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Is This The Hawaii Civil Defence Missile Alert UI?
by Lawrence D'Oliveiro 30 Jan '18

Remember the alert about the incoming missile in Hawaii that turned out to be nonsense? This <https://arstechnica.com/information-technology/2018/01/the-interface-to-sen…> is apparently what the user interface looks like for the system that sends out both test and genuine alerts. It looks like a web page with a random assortment of links. Just off the top of my head, not claiming to be a UI expert here, but I would have a big title across the top of the screen saying either “TEST MODE” or “LIVE MODE” (the latter red, and blinking). Then have a single set of options below, appropriate to the active mode. Even go one better, and do what Japanese railway locomotive drivers do as they see signs at the side of the track: say out loud what the signs mean, before taking appropriate action.

The SCO Vs IBM Zombie Shambles On
by Peter Reutemann 29 Jan '18

29 Jan '18

'At the end of last October, the 10th Circuit issued an opinion overturning the lower court's summary judgement in favor of IBM on one of SCO's claims, sending it back to the lower court for trial. Shortly thereafter, IBM filed for a re-hearing en banc. On January 2nd, the 10th circuit essentially denied IBM's request, issuing a slightly revised opinion with the same conclusions and result. The charge being reheard accuses IBM of "stealing and improperly using [SCO's] source code to strengthen its own operating system, thereby committing the tort of unfair competition by means of misappropriation" -- though that charged is based on an implied duty that SCO says IBM incurred by entering into a development relationship with SCO. "SCO believes that IBM merely pretended to go along with the arrangement in order to gain access to Santa Cruz's coveted source code." The court's 46-page document adds that "We are now almost fifteen years into this litigation."' -- source: https://yro.slashdot.org/story/18/01/29/0213203 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Intel Told Chinese Firms of Meltdown Flaws Before the US Government
by Peter Reutemann 29 Jan '18

29 Jan '18

'According to The Wall Street Journal, Intel initially told a handful of customers about the Meltdown and Spectre vulnerabilities, including Chinese tech companies like Alibaba and Lenovo, before the U.S. government. As a result, the Chinese government could have theoretically exploited the holes to intercept data before patches were available. Engadget reports: An Intel spokesman wouldn't detail who the company had informed, but said that the company couldn't notify everyone (including U.S. officials) in time because Meltdown and Spectre had been revealed early. Lenovo said the information was protected by a non-disclosure agreement. Alibaba has suggested that any accusations of sharing info with the Chinese government was "speculative and baseless," but this doesn't rule out officials intercepting details without Alibaba's knowledge. There's no immediate evidence to suggest that China has taken advantage of the flaws, but that's not the point -- it's that the U.S. government could have helped coordinate disclosures to ensure that enough companies had fixes in place.

Are the BSDs Dying? Some Security Researchers Think So
by Peter Reutemann 26 Jan '18

26 Jan '18

'The BSDs have lost the battle for mindshare to Linux, and that may well bode ill for the future sustainability of the BSDs as viable, secure operating systems, writes CSO's JM Porup. The reason why is a familiar refrain: more eyeballs mean more secure code. Porup cites the work of Ilja von Sprundel, director of penetration testing at IOActive, who, noting the "small number of reported BSD kernel vulnerabilities compared to Linux," dug into BSD source code. His search 'easily' turned up about 115 kernel bugs. Porup looks at the relative security of OpenBSD, FreeBSD and NetBSD, the effect on Mac OS, and why, despite FreeBSD's relative popularity, OpenBSD may be the most likely to survive.' -- source: https://bsd.slashdot.org/story/18/01/26/1636229 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Senator Asks FBI Director To Justify His 'Ill-Informed' Policy Proposal For Encryption
by Peter Reutemann 26 Jan '18

26 Jan '18

'In a speech earlier this month, FBI Director Christopher Wray said the inability of law enforcement authorities to access data from electronic devices due to powerful encryption is an "urgent public safety issue." He proposed that Silicon Valley companies should add a backdoor to their encryption so that they could both "provide data security and permit lawful access with a court order." One person is not amused by Wray's proposal. Senator Ron Wyden criticized Wray on Thursday for not consulting him before going public with the proposal for encryption. Wyden said today, via Gizmodo: Your stated position parrots the same debunked arguments espoused by your predecessors, all of whom ignored the widespread and vocal consensus of cryptographers. For years, these experts have repeatedly stated that what you are asking for is not, in fact, possible. Building secure software is extremely difficult, and vulnerabilities are often introduced inadvertently in the design process. Eliminating these vulnerabilities is a mammoth task, and experts are unified in their opinion that introducing deliberate vulnerabilities would likely create catastrophic unintended consequences that could debilitate software functionality and security entirely. [...] I would like to learn more about how you arrived at and justify this ill-informed policy proposal. Please provide me with a list of the cryptographers with whom you've personally discussed this topic since our July 2017 meeting and specifically identify those experts who advised you that companies can feasibly design government access features into their products without weakening cybersecurity.

Hammered by the finance of physics and the weaponisation of optimisation, Moore’s Law has hit the wall, bounced off - and reversed direction. We’re driving backwards now: all things IT will become slower, harder and more expensive. Actually economics probably had more to do with it than physics, as PC sales have been slowing over the past decade.

City of Barcelona Dumps Windows For Linux and Open Source Software
by Peter Reutemann 24 Jan '18

24 Jan '18

'The City of Barcelona is migrating its computer systems away from the Windows platform, reports the Spanish newspaper El País. The City's strategy is first to replace all user applications with open-source alternatives, until the underlying Windows operating system is the only proprietary software remaining. In a final step, the operating system will be replaced with Linux... According to Francesca Bria, the Commissioner of Technology and Digital Innovation at the City Council, the transition will be completed before the current administration's mandate ends in spring 2019. For starters, the Outlook mail client and Exchange Server will be replaced with Open-Xchange. In a similar fashion, Internet Explorer and Office will be replaced with Firefox and LibreOffice, respectively. The Linux distribution eventually used will probably be Ubuntu, since the City of Barcelona is already running 1,000 Ubuntu-based desktops as part of a pilot... Barcelona is the first municipality to have joined the European campaign 'Public Money, Public Code'. This campaign is an initiative of the Free Software Foundation Europe (FSFE) and revolves around an open letter advocating that publicly funded software should be free. Currently, this call to public agencies is supported by more than 100 organisations and almost 15,000 individuals. With the new open-source strategy, Barcelona's City Council aims to avoid spending large amounts of money on licence-based software and to reduce its dependence on proprietary suppliers through contracts that in some cases have been closed for decades.' -- source: https://linux.slashdot.org/story/18/01/15/0415219 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Firefox 58 Gets Graphics Speed Boost, Web App Abilities
by Peter Reutemann 23 Jan '18

'Mozilla released on Tuesday a new version of its Firefox Quantum browser, boosting its graphics speed and improving a couple of new technologies designed to make the web more powerful. From a report: The browser, version 58, is the first major update since Mozilla's recovery plan hit full stride in November with the debut of Firefox Quantum. Speed is of the essence in Mozilla's recovery plan, and Firefox 58 does better than its predecessor in some graphics tasks by splitting work better across the multiple processor cores that computer chips have these days. The result should be scrolling that's smooth, uninterrupted by the stuttering that in computing circles goes by the disparaging term "jank." [...] Firefox 58 helps with two new web technologies. One, called WebAssembly, provides for dramatically faster web apps. Firefox 58 can get WebAssembly software running faster so you don't have to twiddle your thumbs waiting as long after clicking a link. Another is progressive web apps (PWAs), an initiative that came out of Google to help make the web a better match for the apps we all drop on our phones.' -- source: https://tech.slashdot.org/story/18/01/23/150206 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Various checks are first applied, to try to ensure that the machines being redirected don’t happen to be run by security researchers, for example. Each member of the consortium is activated for serving this malware in turn; then when it is exposed, it is abandoned and the operators move on to the next one. <https://arstechnica.com/information-technology/2018/01/malvertising-factory…>

Has the Decades-Old Floating Point Error Problem Been Solved?
by Peter Reutemann 22 Jan '18

22 Jan '18

'Wednesday a company called Bounded Floating Point announced a "breakthrough patent in processor design, which allows representation of real numbers accurate to the last digit for the first time in computer history. This bounded floating point system is a game changer for the computing industry, particularly for computationally intensive functions such as weather prediction, GPS, and autonomous vehicles," said the inventor, Alan Jorgensen, PhD. "By using this system, it is possible to guarantee that the display of floating point values is accurate to plus or minus one in the last digit..." The innovative bounded floating point system computes two limits (or bounds) that contain the represented real number. These bounds are carried through successive calculations. When the calculated result is no longer sufficiently accurate the result is so marked, as are all further calculations made using that value. It is fail-safe and performs in real time. Jorgensen is described as a cyber bounty hunter and part time instructor at the University of Nevada, Las Vegas teaching computer science to non-computer science students. In November he received US Patent number 9,817,662 -- "Apparatus for calculating and retaining a bound on error during floating point operations and methods thereof." But in a followup, HPCwire reports: After this article was published, a number of readers raised concerns about the originality of Jorgensen's techniques, noting the existence of prior art going back years. Specifically, there is precedent in John Gustafson's work on unums and interval arithmetic both at Sun and in his 2015 book, The End of Error, which was published 19 months before Jorgensen's patent application was filed. We regret the omission of this information from the original article.' -- source: https://science.slashdot.org/story/18/01/21/0157230 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google’s Fuchsia OS on the Pixelbook: It works! It actually works!
by Peter Reutemann 21 Jan '18

21 Jan '18

'Google currently has two OSes on the market: Android and Chrome OS. The company is never one to leave a successful product alone in the marketplace, though, so it's also developing a third operating system called "Fuchsia." When we last checked in on the experimental OS in May 2017, calling it an "OS" was a bit of a stretch. We only got the system UI up and running on top of Android, where it then functioned like an app. The UI offered a neat multi-window system, but mostly it was just a bunch of placeholder graphics. Nothing worked. It has been hard to check in on Fuchsia since. The Fuchsia system UI, which was written with a cross-platform SDK called "Flutter," quickly shut down the Android (and iOS) compatible builds. Fuchsia has a Vulkan-based graphics stack, and no emulator supports the new-ish graphics API. The only way to get Fuchsia up and running again was with actual hardware, and the only supported devices were Intel NUC PCs from 2015 and the Acer Switch Alpha 12 laptop. So after the recent news that the Fuchsia team picked the Chrome OS-powered Google Pixelbook as a supported device, we jumped at the chance to get it up and running. And after a little elbow grease, it actually booted. Now, we're not just running the system UI on top of Android like last time, we're running Fuchsia directly on a piece of hardware! This means it's finally time for a deep dive on what Fuchsia looks like in early 2018. Our usual in-development OS testing caveats apply: Fuchsia only started development in 2016 and probably has several years of development time ahead of it. Everything can—and probably will—change between now and release (if a release ever even happens). Google won't even officially acknowledge the OS exists—Fuchsia is a bunch of code sitting on fuchsia.googlesource.com.' -- source: https://arstechnica.com/gadgets/2018/01/googles-fuchsia-os-on-the-pixelbook… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

NHoS/NHSBuntu Gives Up After NHS Trademark Bullying
by Lawrence D'Oliveiro 18 Jan '18

18 Jan '18

The small team of volunteers behind the NHoS project (formerly NHSBuntu) are giving up. They wanted to offer an alternative to the current NHS smartcard implementation system, currently running on Windows, using open-source software. First they rebranded from “NHSBuntu” to “NHoS” (along with “overhauling the previous tooling and branding”), which they thought would address trademark concents from the NHS. But now it seems even this name is considered unacceptable. One of the developers, Marcus Baw, ... said openhealthhub had numerous conversations that had led to "several cancelled-at-the-last minute meetings" with NHS England (NHSE) CIO Will Smart and Paul Rice, head of technology strategy in the Digital Health team. Baw alleged the pair "(unbeknown to us) were also duplicitously negotiating with Microsoft about a new NHS Enterprise Wide Agreement". He added: "In fact I now strongly suspect that the reason we were getting any engagement at all at these levels was in order to strength NHSE negotiating position with Microsoft, by being able to say to M$ 'There is a competitor, we are meeting with them next week'." <http://www.theregister.co.uk/2018/01/18/nhs_thanks_for_all_the_free_work_li…>

A researcher who has published papers on “traffic differentiation” by ISPs tried to submit an app to perform tests to detect this happening on behalf of Iphone users, only to have Apple turn it down on the grounds that it “has no direct benefits to the user”. That is, until word got around about the rejection. Now it seems they are reconsidering. <https://arstechnica.com/information-technology/2018/01/apple-rejects-app-th…>

Hi everyone I hope everyone had a good break and enjoyed the lovely muggy weather in the Waikato... ;-) Unfortunately, I didn't get around to looking into home automation over the break, so currently drawing a blank in terms of topics for next week's meeting.

Hackers can’t dig into latest Xiaomi phone due to GPL violations
by Peter Reutemann 17 Jan '18

17 Jan '18

'Yet another Android OEM is dragging its feet with its GPL compliance. This time, it's Xiaomi with the Mi A1 Android One device, which still hasn't seen a kernel source code release. Android vendors are required to release their kernel sources thanks to the Linux kernel's GPLv2 licensing. The Mi A1 has been out for about three months now, and there's still no source code release on Xiaomi's official github account. Unfortunately, GPL non-compliance is par for the course in the world of Android. Budget SoC company MediaTek once tried charging users for access to GPL'd code. Motorola under Lenovo has been regularly accused of violating the GPL and releasing incomplete sources or sources that differ from the kernel shipping on devices. Unsurprisingly, the majority of these alleged GPL violators are from China, which often plays fast and loose with IP law. Android developers use the source code to create custom kernels that tweak the way a device works, allowing for overclocking, better battery life, or control over the CPU governor. One of the largest custom kernel developers, Francisco Franco, has started a public Twitter campaign to encourage Xiaomi to comply with the GPL.' -- source: https://arstechnica.com/gadgets/2018/01/xiaomi-is-dragging-its-feet-on-the-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Found: New Android malware with never-before-seen spying capabilities
by Peter Reutemann 17 Jan '18

17 Jan '18

'Last year, researchers found what at the time was quite possibly the world's most sophisticated espionage app ever written for the Android mobile operating system. Now, in a discovery that underscores the growing arms race among competing malware developers, researchers have uncovered a new Android spying platform that includes location-based audio recording and other features that have never been seen in the wild before. According to a report published Tuesday by antivirus provider Kaspersky Lab, "Skygofree" is most likely an offensive security product sold by an Italy-based IT company that markets various surveillance wares. With 48 different commands in its latest version, the malware has undergone continuous development since its creation in late 2014. It relies on five separate exploits to gain privileged root access that allows it to bypass key Android security measures. Skygofree is capable of taking pictures, capturing video, and seizing call records, text messages, geolocation data, calendar events, and business-related information stored in device memory. Skygofree also includes the ability to automatically record conversations and noise when an infected device enters a location specified by the person operating the malware. Another never-before-seen feature is the ability to steal WhatsApp messages by abusing the Android Accessibility Service that's designed to help users who have disabilities or who may temporarily be unable to fully interact with a device. A third new feature: the ability to connect infected devices to Wi-Fi networks controlled by attackers. Skygofree also includes other advanced features, including a reverse shell that gives malware operators better remote control of infected devices. The malware also comes with a variety of Windows components that provide among other things a reverse shell, a keylogger, and a mechanism for recording Skype conversations' -- source: https://arstechnica.com/information-technology/2018/01/found-new-android-ma… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Phrase Of The Week: “Foveated Rendering”
by Lawrence D'Oliveiro 16 Jan '18

16 Jan '18

<http://www.theregister.co.uk/2018/01/16/human_limits_of_vr_and_ar/>: By some estimates, given a field of view of 180 degrees, around 74 gigabytes of visual data are available to us each second, but only around 125 megabytes are ultimately processed ... Much of the rest is chucked away before it even gets to the optic nerve. But trying to minimize the rendering workload by concentrating on the fovea (the most detail-sensitive part of the eye, the little spot where the image falls when you “look at” something) is not so simple, given the quirks of how our visual perception actually works. Computer graphics doyen Alvy Ray Smith is reputed to have said “reality is 80 million polygons per second”. I think we can achieve that now, but the pixel rate considered acceptable on a conventional monitor is peanuts compared to that required for VR.

20 Years Later, Has Open Source Changed the World?
by Peter Reutemann 15 Jan '18

15 Jan '18

'"Most code remains closed and proprietary, even though open source now dominates enterprise platforms," notes Matt Asay, former COO at Canonical (and an emeritus board member of the Open Source Initiative). "How can that be?" he asks, in an essay noting it's been almost 20 years since the launch of the Open Source Initiative, arguing that so far open source "hasn't changed the world as promised." [T]he reason most software remains locked up within the four walls of enterprise firewalls is that it's too costly with too small of an ROI to justify open-sourcing it. At least, that's the perception. Such a perception is impossible to break without walking the open source path, which companies are unwilling to walk without upfront proof. See the problem? This chicken-and-egg conundrum is starting to resolve itself, thanks to the forward-looking efforts of Google, Facebook, Amazon, and other web giants that are demonstrating the value of open-sourcing code. Although it's unlikely that a State Farm or Chevron will ever participate in the same way as a Microsoft, we are starting to see companies like Bloomberg and Capital One get involved in open source in ways they never would have considered back when the term "open source" was coined in 1997, much less in 2007. It's a start. Let's also not forget that although we have seen companies use more open source code over the past 20 years, the biggest win for open source since its inception is how it has changed the narrative of how innovation happens in software. We're starting to believe, and for good reason, that the best, most innovative software is open source. The article strikes a hopeful note. "We're now comfortable with the idea that software can, and maybe should, be open source without the world ending. The actual opening of that source, however, is something to tackle in the next 20 years.' -- source: https://news.slashdot.org/story/18/01/14/1627207 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Meltdown and Spectre Patches Bricking Ubuntu 16.04 Computers
by Peter Reutemann 10 Jan '18

10 Jan '18

'Ubuntu Xenial 16.04 users who updated to receive the Meltdown and Spectre patches are reporting they are unable to boot their systems and have been forced to roll back to an earlier Linux kernel image. The issues were reported by a large number of users on the Ubuntu forums and Ubuntu's Launchpad bug tracker. Only Ubuntu users running the Xenial 16.04 series appear to be affected. All users who reported issues said they were unable to boot after upgrading to Ubuntu 16.04 with kernel image 4.4.0-108. Canonical, the company behind Ubuntu OS, deployed Linux kernel image 4.4.0-108 as part of a security update for Ubuntu Xenial 16.04 users, yesterday, on January 9. According to Ubuntu Security Notice USN-3522-1 and an Ubuntu Wiki page, this was the update that delivered the Meltdown and Spectre patches.' -- source: https://news.slashdot.org/story/18/01/10/1634215 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Germany Ban On Online Hate Speech Triggers Debate
by Lawrence D'Oliveiro 10 Jan '18

10 Jan '18

A new law has come into effect in Germany whereby companies like Facebook and Twitter face multi-million-euro fines if they don’t block their users from expressing “hate speech” <http://www.aljazeera.com/news/2018/01/germany-ban-online-hate-speech-trigge…>. Trouble is, this law seems to be a bit of a blunt axe: on the one hand it led to the temporary suspension of the Twitter account of the deputy leader of the far-right AfD party, Beatrix von Storch. But also caught up in the net was the account of the satirical “Titanic” magazine, after it parodied a phrase used by von Storch. Then again, if you are seen to clamp down too hard on particular points of view, that gives political ammunition to those who claim they are being censored...

Re-Assembling Shredded Stasi Records
by Lawrence D'Oliveiro 09 Jan '18

09 Jan '18

During the last days of the German Democratic Republic (a.k.a. East Germany), the Stasi secret police tried to destroy the more incriminating records they had been keeping on their own citizens. They were only partially successful. And even then, there has been an ongoing project to reassemble those torn-up pieces of paper, by scanning them and doing pattern-recognition to match up the image pieces. Seems the easiest ones are fairly manageable, but now they are getting to smaller fragments, which are proving more of a challenge. <https://www.techdirt.com/articles/20180105/07120838936/stasis-tiny-torn-up-…>

Another Fork Takes Over The Original Project
by Lawrence D'Oliveiro 08 Jan '18

08 Jan '18

Open-source software projects can fork for various reasons. Sometimes a bunch of developers want to go in a different direction. Other times the original project appears to be languishing, but those in charge are reluctant to give up control. Sometimes the forks peter out, other times they coexist happily (or unhappily) with the original project, occasionally they even absorb the original project. This <http://www.theregister.co.uk/2018/01/08/lede_and_openwrt_merge/> seems to be one of the latter cases: the LEDE fork of OpenWRT is merging back in, but the merger will be “governed under the rules of the LEDE project”.

Can You Install Linux On a 1993 PC?
by Peter Reutemann 07 Jan '18

07 Jan '18

'The oldest x86 CPU that the Linux kernel supports today is theoretically the 486. However is this theory actually true in practice? I decided to put this theory to the test in my project. His site describes installing Gentoo Linux on an "ancient" IBM PS/1 Consultant 2133 19C (released in 1993), with 64MB SIMM-72 RAM. (Though to speed things up, he compiled that minimal version of Gentoo on a modern Thinkpad T430 released in 2012.) "Due to the age of the PC, the BIOS only supports booting from the floppy drive or internal HDD," so there was also some disk partitioning and kernel configuration. ("Must disable 64-bit kernel for obvious reasons!") A half-hour video shows that it takes almost 11 minutes just to boot up -- and five and a half minutes to shut down. "Despite the many roadblocks I faced, I was impressed by the level of support Linux has for ancient hardware like this." And there's one more added bonus. "Given the age of the 486 (1989 technology), it does not support branch prediction... Ironically this makes it safe from the Meltdown and Spectre attacks."' -- source: https://linux.slashdot.org/story/18/01/07/228222 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Can We Replace Intel x86 With an Open Source Chip?
by Peter Reutemann 07 Jan '18

07 Jan '18

'Perhaps the Meltdown and Spectre bugs are the impetus for making long-overdue changes to the core DNA of the semiconductor industry and how chip architectures are designed... Linux (and other related FOSS tech that forms the overall stack) is now a mainstream operating system that forms the basis of public cloud infrastructure and the foundational software technology in mobile and Internet of Things (IoT)... We need to develop a modern equivalent of an OpenSPARC that any processor foundry can build upon without licensing of IP, in order to drive down the costs of building microprocessors at immense scale for the cloud, for mobile and the IoT. It makes the $200 smartphone as well as hyperscale datacenter lifecycle management that much more viable and cost-effective. Just as Linux and open source transformed how we view operating systems and application software, we need the equivalent for microprocessors in order to move out of the private datacenter rife with these legacy issues and into the green field of the cloud... The fact that we have these software technologies that now enable us to easily abstract from the chip hardware enables us to correct and improve the chips through community efforts as needs arise... We need to stop thinking about microprocessor systems' architectures as these licensed things that are developed in secrecy by mega-companies like Intel or AMD or even ARM... The reality is that we now need to create something new, free from any legacy entities and baggage that has been driving the industry and dragging it down the past 40 years. Just as was done with Linux. The bigger question is which chip should take its place. "I don't see ARM donating its IP to this effort, and I think OpenSPARC may not be it either. Perhaps IBM OpenPOWER? It would certainly be a nice gesture of Big Blue to open their specification up further without any additional licensing, and it would help to maintain and establish the company's relevancy in the cloud going forward. "RISC-V, which is being developed by UC Berkeley, is completely Open Source."' -- source: https://news.slashdot.org/story/18/01/06/0424200 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

After Intel ME, Researchers Find Security Bug In AMD's SPS Secret Chip-on-Chip
by Peter Reutemann 07 Jan '18

07 Jan '18

'AMD has fixed, but not yet released BIOS/UEFI/firmware updates for the general public for a security flaw affecting the AMD Secure Processor. This component, formerly known as AMD PSP (Platform Security Processor), is a chip-on-chip security system, similar to Intel's much-hated Management Engine (ME). Just like Intel ME, the AMD Secure Processor is an integrated coprocessor that sits next to the real AMD64 x86 CPU cores and runs a separate operating system tasked with handling various security-related operations. The security bug is a buffer overflow that allows code execution inside the AMD SPS TPM, the component that stores critical system data such as passwords, certificates, and encryption keys, in a secure environment and outside of the more easily accessible AMD cores. Intel fixed a similar flaw last year in the Intel ME.' -- source: https://hardware.slashdot.org/story/18/01/07/2015226 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Munich Council: To Hell With Linux, We're Going Full Windows in 2020
by Peter Reutemann 04 Jan '18

04 Jan '18

'The German city of Munich, which received much popularity back in the day when it first ditched Microsoft's services in favor of open-source software, has now agreed to stop using Linux and switch back to Windows. If the decision is ratified by the full council in two weeks, Windows 10 will start rolling out across the city in 2020. From a report: A coalition of Social Democrats and Conservatives on the committee voted for the Windows migration last week, Social Democrat councillor Anne Hubner told The Register. Munich rose to fame in the open-source world for deciding to use Linux and LibreOffice to make the city independent from the claws of Microsoft. But the plan was never fully realised -- mail servers, for instance, eventually wound up migrating to Microsoft Exchange -- and in February the city council formally voted to end Linux migration and go back to Microsoft. Hubner said the city has struggled with LiMux adoption. "Users were unhappy and software essential for the public sector is mostly only available for Windows," she said. She estimated about half of the 800 or so total programs needed don't run on Linux and "many others need a lot of effort and workarounds." Hubner added, "in the past 15 years, much of our efforts were put into becoming independent from Microsoft," including spending "a lot of money looking for workarounds" but "those efforts eventually failed." A full council vote on Windows 10 2020 migration is set for November 23, Hubner said. However, the Social Democrats and Conservatives have a majority in the council, and the outcome is expected to be the same as in committee.' -- source: https://news.slashdot.org/story/17/11/13/1714220 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

They also can't connect with a home-security system or smart-home gadgets that work with Apple and Google software. And, of course, the lock can't be accessed by businesses other than Amazon. No Walmart, no UPS, no local dog-walking company. And so Amazon becomes a gatekeeper (literally) for access to your very home.

All 500 of the World's Top 500 Supercomputers Are Running Linux
by Peter Reutemann 19 Dec '17

19 Dec '17

'Linux rules supercomputing. This day has been coming since 1998, when Linux first appeared on the TOP500 Supercomputer list. Today, it finally happened: All 500 of the world's fastest supercomputers are running Linux. The last two non-Linux systems, a pair of Chinese IBM POWER computers running AIX, dropped off the November 2017 TOP500 Supercomputer list. When the first TOP500 supercomputer list was compiled in June 1993, Linux was barely more than a toy. It hadn't even adopted Tux as its mascot yet. It didn't take long for Linux to start its march on supercomputing. >From when it first appeared on the TOP500 in 1998, Linux was on its way to the top. Before Linux took the lead, Unix was supercomputing's top operating system. Since 2003, the TOP500 was on its way to Linux domination. By 2004, Linux had taken the lead for good. This happened for two reasons: First, since most of the world's top supercomputers are research machines built for specialized tasks, each machine is a standalone project with unique characteristics and optimization requirements. To save costs, no one wants to develop a custom operating system for each of these systems. With Linux, however, research teams can easily modify and optimize Linux's open-source code to their one-off designs. The semiannual TOP500 Supercomputer List was released yesterday. It also shows that China now claims 202 systems within the TOP500, while the United States claims 143 systems.' -- source: https://linux.slashdot.org/story/17/11/14/2223227 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
