Weta Digital’s Technology Division Sold To US Firm
by Lawrence D'Oliveiro 01 Aug '25

01 Aug '25

Let me see if I understand this article <https://www.nzherald.co.nz/business/sir-peter-jackson-to-sell-weta-digital-…> correctly: the part of Weta Digital that used to develop the in-house 3D graphics/effects tools that they use in all those movies is being sold to US-based Unity Software. The part that is left will be called “WetaFX”, and will become a customer of Unity for the use of those tools, no longer doing its own development in-house. By the way, I’ve been looking at the Unity site <https://unity.com/>, and it looks like all their products are rentware (subscription-based).

New systemd update will bring Windows’ infamous Blue Screen of Death to Linux
by Peter Reutemann 18 Nov '24

18 Nov '24

'Windows' infamous "Blue Screen of Death" is a bit of a punchline. People have made a hobby of spotting them out in the wild, and in some circles, they remain a byword for the supposed flakiness and instability of PCs. To this day, networked PCs in macOS are represented by beige CRT monitors displaying a BSOD. But the BSOD is supposed to be a diagnostic tool, an informational screen that technicians can use to begin homing in on the problem that caused the crash in the first place; that old Windows' BSOD error codes were often so broad and vague as to be useless doesn't make the idea a bad one. Today, version 255 of the Linux systemd project honors that original intent by adding a systemd-bsod component that generates a full-screen display of some error messages when a Linux system crashes. The systemd-bsod component is currently listed as "experimental" and "subject to change." But the functionality is simple: any logged error message that reaches the LOG_EMERG level will be displayed full-screen to allow people to take a photo or write it down. Phoronix reports that, as with BSODs in modern Windows, the Linux version will also generate a QR code to make it easier to look up information on your phone.' -- source: https://arstechnica.com/gadgets/2023/12/linux-distros-are-about-to-get-a-ki… 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/

Juice TV Hiccup
by Lawrence D'Oliveiro 15 Oct '24

15 Oct '24

Currently when I switch to FreeView Channel 200, it shows a frozen image with the text “Cinegy” and “Demo Version” on it. Searching for that name takes me to a site that talks about “software defined television”. Either their product licence has expired, or they never had one in the first place ...

List Of IPTV Resources
by Lawrence D'Oliveiro 22 Sep '24

22 Sep '24

This user <https://github.com/iptv-org> just popped up in my GitHub feed. One repo <https://github.com/iptv-org/iptv> claims to be a list of links to over 8000 streaming TV channels from nations all over the world, while the other is a list of tools*, providers and other resources. Do be aware it’s a bit of a mixed bag: yes, there are legitimate channels (no encryption so far that I have noticed), but also some dubious-looking links. *Oddly, FFmpeg and youtube-dl aren’t in the list.

Tip For Repairing Ancient Linux Installations
by Lawrence D'Oliveiro 02 Apr '24

02 Apr '24

Here’s the scenario: there is a malfunctioning server running a really ancient Linux installation (e.g. 2.6.x-series kernel). You boot up with a reasonably recent copy of SystemRescue, mount the machine’s filesystem, try to chroot into it and run a shell ... and it segfaults. Seems there has been a subtle incompatible change in Linux kernel behaviour since those times, to do with the disabling of something called the “vsyscall” mechanism (which is specific to 64-bit x86-based machines, I understand). This was supposed to be a way to speed up certain commonly-executed system calls (I think getting the system time was one of them) by allowing direct transfers to certain entry points with fixed memory addresses for invoking them. It was later decided this was a bad idea (I think for security reasons). The mechanism has not been completely removed (yet), but nowadays it is disabled by default. To get around this, you need to boot SystemRescue with a change to the kernel command-line parameters, adding this item vsyscall=emulate After you get to a shell, you can confirm that this setting is in effect by checking the /proc/self/maps file (the memory mappings for your own process). At the bottom, there should be an entry with “[vdso]” in it, and below that another line with “[vsyscall]”. The presence of the latter line indicates that vsyscall emulation is in effect. This is not present when I check a process on my own machine, for example. Linus is legendary for being a stickler for never, ever breaking backward compatibility for userland. So the reasons for turning this off must have been pretty compelling, for him to agree to it. But the compromise is, it’s still there to be enabled if you really, really need it. There’s a bit more technical info here <https://0xax.gitbooks.io/linux-insides/content/SysCall/linux-syscall-3.html>, if you are interested. By the way, the above page is part of a book beginning here <https://0xax.gitbooks.io/linux-insides/content/>, about the insides of the Linux kernel. The whole book seems to be accessible from that link, but if you step up a level, the site doesn’t seem to have any idea about the existence of that book.

'Paying People To Work on Open Source is Good Actually'
by Peter Reutemann 01 Mar '24

01 Mar '24

'Jacob Kaplan-Moss, one of the lead developers of Django, writes in a long post that he says has come from a place of frustration: [...] Instead, every time a maintainer finds a way to get paid, people show up to criticize and complain. Non-OSI licenses "don"t count" as open source. Someone employed by Microsoft is "beholden to corporate interests" and not to be trusted. Patreon is "asking for handouts." Raising money through GitHub sponsors is "supporting Microsoft's rent-seeking." VC funding means we're being set up for a "rug pull" or "enshitification." Open Core is "bait and switch." None of this is hypothetical; each of these examples are actual things I've seen said about maintainers who take money for their work. One maintainer even told me he got criticized for selling t-shirts! Look. There are absolutely problems with every tactic we have to support maintainers. It's true that VC investment comes with strings attached that often lead to problems down the line. It sucks that Patreon or GitHub (and Stripe) take a cut of sponsor money. The additional restrictions imposed by PolyForm or the BSL really do go against the Freedom 0 ideal. I myself am often frustrated by discovering that some key feature I want out of an open core tool is only available to paid licensees. But you can criticize these systems while still supporting and celebrating the maintainers! Yell at A16Z all you like, I don't care. (Neither do they.) But yelling at a maintainer because they took money from a VC is directing that anger in the wrong direction. The structural and societal problems that make all these different funding models problematic aren't the fault of the people trying to make a living doing open source. It's like yelling at someone for shopping at Dollar General when it's the only store they have access to. Dollar General's predatory business model absolutely sucks, as do the governmental policies that lead to food deserts, but none of that is on the shoulders of the person who needs milk and doesn't have alternatives.' -- source: https://news.slashdot.org/story/24/02/29/0746221 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/

HDMI Forum Rejects Open-Source HDMI 2.1 Driver Support Sought By AMD
by Peter Reutemann 01 Mar '24

01 Mar '24

'Michael Larabel, reporting at Phoronix: One of the limitations of AMD's open-source Linux graphics driver has been the inability to implement HDMI 2.1+ functionality on the basis of legal requirements by the HDMI Forum. AMD engineers had been working to come up with a solution in conjunction with the HDMI Forum for being able to provide HDMI 2.1+ capabilities with their open-source Linux kernel driver, but it looks like those efforts for now have concluded and failed. For three years there has been a bug report around 4K(a)120Hz being unavailable via HDMI 2.1 on the AMD Linux driver. Similarly, there have been bug reports like 5K @ 240Hz not possible either with the AMD graphics driver on Linux. As covered back in 2021, the HDMI Forum closing public specification access is hurting open-source support. AMD as well as the X.Org Foundation have been engaged with the HDMI Forum to try to come up with a solution to be able to provide open-source implementations of the now-private HDMI specs. AMD Linux engineers have spent months working with their legal team and evaluating all HDMI features to determine if/how they can be exposed in their open-source driver. AMD had code working internally and then the past few months were waiting on approval from the HDMI Forum. Sadly, the HDMI Forum has turned down AMD's request for open-source driver support.' -- source: https://it.slashdot.org/story/24/02/29/076217 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/

'"Today, the KDE Community is announcing a new major release of Plasma 6.0 and Gear 24.02," writes longtime Slashdot reader jrepin. "The new version brings new windows and desktop overview effects, improved color management, a cleaner theme, better overall performance, and much more." From the announcement: KDE Plasma is a modern, feature-rich desktop environment for Linux-based operating systems. Known for its sleek design, customizable interface, and extensive set of applications, it is also open source, devoid of ads, and makes protecting your privacy and personal data a priority. With Plasma 6, the technology stack has undergone two major upgrades: a transition to the latest version of the application framework, Qt 6, and a migration to the modern Linux graphics platform, Wayland. We will continue providing support for the legacy X11 session for users who prefer to stick with it for now. [...] KDE Gear 24.02 brings many applications to Qt 6. In addition to the changes in Breeze, many applications adopted a more frameless look for their interface.' -- source: https://tech.slashdot.org/story/24/02/28/2137237 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/

GitHub besieged by millions of malicious repositories in ongoing attack
by Peter Reutemann 29 Feb '24

29 Feb '24

'GitHub is struggling to contain an ongoing attack that’s flooding the site with millions of code repositories. These repositories contain obfuscated malware that steals passwords and cryptocurrency from developer devices, researchers said. The malicious repositories are clones of legitimate ones, making them hard to distinguish to the casual eye. An unknown party has automated a process that forks legitimate repositories, meaning the source code is copied so developers can use it in an independent project that builds on the original one. The result is millions of forks with names identical to the original one that add a payload that’s wrapped under seven layers of obfuscation. To make matters worse, some people, unaware of the malice of these imitators, are forking the forks, which adds to the flood.' -- source: https://arstechnica.com/security/2024/02/github-besieged-by-millions-of-mal… 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/

Tumblr and Wordpress Are Preparing To Sell User Data To OpenAI and Midjourney, Report Says

'Tumblr and Wordpress are preparing to sell user data to Midjourney and OpenAI, 404Media reported Tuesday, citing a source with internal knowledge about the deals and internal documents. From the report: The exact types of data from each platform going to each company are not spelled out in documentation we've reviewed, but internal communications reviewed by 404 Media make clear that deals between Automattic, the platforms' parent company, and OpenAI and Midjourney are imminent. The internal documentation details a messy and controversial process within Tumblr itself. One internal post made by Cyle Gage, a product manager at Tumblr, states that a query made to prepare data for OpenAI and Midjourney compiled a huge number of user posts that it wasn't supposed to. It is not clear from Gage's post whether this data has already been sent to OpenAI and Midjourney, or whether Gage was detailing a process for scrubbing the data before it was to be sent.

US Government Demands Memory-Safe Programming Languages
by Lawrence D'Oliveiro 28 Feb '24

28 Feb '24

The US Office of the National Cyber Director has put out a report on “a path towards secure and measurable software” <https://devclass.com/2024/02/27/white-house-demands-memory-safe-programming…>. It talks a lot about memory safety, including hardware techniques such as the old “capabilities” idea being resurrected in the CHERI project. And the Rust Foundation has chimed in with some comments about use of their language which is specifically designed to enforce memory safety. But a group of C++ fans has counterclaimed that memory safety is only “a very small part of security”, and that “C++ benefits from having a formal specification, a fully-specified memory model, and an active community of users and implementers”, and that education can improve the quality of code written in C and C++. It also tries to imply that Rust is somehow less desirable because it lacks a formal specification.

Is Windows 64-Bit Yet?
by Lawrence D'Oliveiro 27 Feb '24

27 Feb '24

Given that 64-bit Windows has been shipping for so long, you would think most Windows software, particularly Microsoft’s own software, would have made the transition from 32-bit long ago. After all, on a typical 64-bit Linux system, everything is 64-bit, and has been that way since the early days. So I was mildly surprised to discover that Visual Studio only became 64-bit in November 2021. And today I am even more surprised to discover that the change broke its own Windows Forms framework, and a fix is still not available to this day <https://devclass.com/2024/02/26/microsoft-struggles-to-address-fallout-from…>.

The State Of IoT
by Lawrence D'Oliveiro 23 Feb '24

23 Feb '24

This backflip from Microsoft <https://www.theregister.com/2024/02/21/microsoft_azure_iot_central/> retracting an earlier announcement that seemingly undermined a major part of its “Internet-of-Things” efforts seems to do little to clear the confusion. I found this part of the report quite revealing: The insider also pointed out that vendors struggle to produce value for organizations developing and deploying IoT applications. While the industry underestimated the scale of the challenge in connecting thousands of sensors, each of which could generate 86,400 values per day, it also failed to form a commercial model that worked for everyone. Vendors were focused only on owning the platform and were reluctant to build applications on anyone else's, creating a stalemate, the insider said. Meanwhile, the “maker” movement continues on its merry way, building its applications and toolkits on (and for) open-source platforms like the Raspberry Pi and Arduino, while completely failing to spend billions of dollars on proprietary products. And the proprietary companies can do nothing but search desperately for some lever that will give them that valuable vendor lock-in, but all they can achieve is wrestle each other to a stalemate. Me, I consider that a win-win situation. ;)

Linux Becomes a CVE Numbering Authority (Like Curl and Python). Is This a Turning Point?
by Peter Reutemann 19 Feb '24

19 Feb '24

'From a blog post by Greg Kroah-Hartman: As was recently announced, the Linux kernel project has been accepted as a CVE Numbering Authority (CNA) for vulnerabilities found in Linux. This is a trend, of more open source projects taking over the haphazard assignments of CVEs against their project by becoming a CNA so that no other group can assign CVEs without their involvment. Here's the curl project doing much the same thing for the same reasons. I'd like to point out the great work that the Python project has done in supporting this effort, and the OpenSSF project also encouraging it and providing documentation and help for open source projects to accomplish this. I'd also like to thank the cve.org group and board as they all made the application process very smooth for us and provided loads of help in making this all possible. As many of you all know, I have talked a lot about CVEs in the past, and yes, I think the system overall is broken in many ways, but this change is a way for us to take more responsibility for this, and hopefully make the process better over time. It's also work that it looks like all open source projects might be mandated to do with the recent rules and laws being enacted in different parts of the world, so having this in place with the kernel will allow us to notify all sorts of different CNA-like organizations if needed in the future. Kroah-Hartman links to his post on the kernel mailing list for "more details about how this is all going to work for the kernel." [D]ue to the layer at which the Linux kernel is in a system, almost any bug might be exploitable to compromise the security of the kernel, but the possibility of exploitation is often not evident when the bug is fixed. Because of this, the CVE assignment team are overly cautious and assign CVE numbers to any bugfix that they identify. This explains the seemingly large number of CVEs that are issued by the Linux kernel team... No CVEs will be assigned for unfixed security issues in the Linux kernel, assignment will only happen after a fix is available as it can be properly tracked that way by the git commit id of the original fix. No CVEs will be assigned for any issue found in a version of the kernel that is not currently being actively supported by the Stable/LTS kernel team. alanw (Slashdot reader #1,822) worries this could overwhelm the CVE infrastructure, pointing to an ongoing discussion at LWN.net. But reached for a comment, Greg Kroah-Hartman thinks there's been a misunderstanding. He told Slashdot that the CVE group "explicitly asked for this as part of our application... so if they are comfortable with it, why is no one else?"' -- source: https://linux.slashdot.org/story/24/02/17/1811258 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/

Nginx core developer quits project in security dispute, starts “freenginx” fork
by Peter Reutemann 16 Feb '24

16 Feb '24

'A core developer of Nginx, currently the world's most popular web server, has quit the project, stating that he no longer sees it as "a free and open source project… for the public good." His fork, freenginx, is "going to be run by developers, and not corporate entities," writes Maxim Dounin, and will be "free from arbitrary corporate actions." Dounin is one of the earliest and still most active coders on the open source Nginx project and one of the first employees of Nginx, Inc., a company created in 2011 to commercially support the steadily growing web server. Nginx is now used on roughly one-third of the world's web servers, ahead of Apache. Nginx Inc. was acquired by Seattle-based networking firm F5 in 2019. Later that year, two of Nginx's leaders, Maxim Konovalov and Igor Sysoev, were detained and interrogated in their homes by armed Russian state agents. Sysoev's former employer, Internet firm Rambler, claimed that it owned the rights to Nginx's source code, as it was developed during Sysoev's tenure at Rambler (where Dounin also worked). While the criminal charges and rights do not appear to have materialized, the implications of a Russian company's intrusion into a popular open source piece of the web's infrastructure caused some alarm. Sysoev left F5 and the Nginx project in early 2022. Later that year, due to the Russian invasion of Ukraine, F5 discontinued all operations in Russia. Some Nginx developers still in Russia formed Angie, developed in large part to support Nginx users in Russia. Dounin technically stopped working for F5 at that point, too, but maintained his role in Nginx "as a volunteer," according to Dounin's mailing list post. Dounin writes in his announcement that "new non-technical management" at F5 "recently decided that they know better how to run open source projects. In particular, they decided to interfere with security policy nginx uses for years, ignoring both the policy and developers' position." While it was "quite understandable," given their ownership, Dounin wrote that it means he was "no longer able to control which changes are made in nginx," hence his departure and fork.' -- source: https://arstechnica.com/information-technology/2024/02/nginx-key-developer-… 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 Project's OpenGL Support On Apple Silicon Officially Surpasses Apple's
by Peter Reutemann 16 Feb '24

16 Feb '24

'Andrew Cunningham reports via Ars Technica: For around three years now, the team of independent developers behind the Asahi Linux project has worked to support Linux on Apple Silicon Macs, despite Apple's total lack of involvement. Over the years, the project has gone from a "highly unstable experiment" to a "surprisingly functional and usable desktop operating system." Even Linus Torvalds has used it to run Linux on Apple's hardware. The team has been steadily improving its open source, standards-conformant GPU driver for the M1 and M2 since releasing them in December 2022, and today, the team crossed an important symbolic milestone: The Asahi driver's support for the OpenGL and OpenGL ES graphics have officially passed what Apple offers in macOS. The team's latest graphics driver fully conforms with OpenGL version 4.6 and OpenGL ES version 3.2, the most recent version of either API. Apple's support in macOS tops out at OpenGL 4.1, announced in July 2010. Developer Alyssa Rosenzweig wrote a detailed blog post that announced the new driver, which had to pass "over 100,000 tests" to be deemed officially conformant. The team achieved this milestone despite the fact that Apple's GPUs don't support some features that would have made implementing these APIs more straightforward. "Regrettably, the M1 doesn't map well to any graphics standard newer than OpenGL ES 3.1," writes Rosenzweig. "While Vulkan makes some of these features optional, the missing features are required to layer DirectX and OpenGL on top. No existing solution on M1 gets past the OpenGL 4.1 feature set... Without hardware support, new features need new tricks. Geometry shaders, tessellation, and transform feedback become compute shaders. Cull distance becomes a transformed interpolated value. Clip control becomes a vertex shader epilogue. The list goes on." Now that the Asahi GPU driver supports the latest OpenGL and OpenGL ES standards -- released in 2017 and 2015, respectively -- the work turns to supporting the low-overhead Vulkan API on Apple's hardware. Vulkan support in macOS is limited to translation layers like MoltenVK, which translates Vulkan API calls to Metal ones that the hardware and OS can understand. [...] Rosenzweig's blog post didn't give any specific updates on Vulkan except to say that the team was "well on the road" to supporting it. In addition to supporting native Linux apps, supporting more graphics APIs in Asahi will allow the operating system to take better advantage of software like Valve's Proton, which already has a few games written for x86-based Windows PCs running on Arm-based Apple hardware.

Firefox Maker Mozilla Is Cutting 60 Jobs After Naming New CEO
by Peter Reutemann 14 Feb '24

14 Feb '24

'Less than a week after naming Laura Chambers as interim CEO, Firefox's maker Mozilla said it is cutting about 60 jobs, or 5% of its workforce. The cuts are primarily in the product development organization. Bloomberg reports: "We're scaling back investment in some product areas in order to focus on areas that we feel have the greatest chance of success," Mozilla said in a statement. "We intend to re-prioritize resources against products like Firefox Mobile, where there's a significant opportunity to grow and establish a better model for the industry." Mozilla last cut a significant number of jobs four years ago at the height of the Covid-19 pandemic. The not-for-profit company, which competes with Alphabet Inc.'s Google Chrome, Apple Inc.'s Safari and Microsoft Corp.'s Edge, has been grappling with sliding market share of its Firefox web browser in recent years. So far in 2024, the tech sector has cut 32,000 jobs.

Recently discovered this site <https://hpc-wiki.info/hpc/HPC_Wiki>, which gives some useful introductory info to those wanting to learn how to program a supercomputer (or just curious about the process). For example, here <https://hpc-wiki.info/hpc/MPI> is an intro to one parallelization architecture, called MPI, and here <https://hpc-wiki.info/hpc/OpenMP> is an intro to another one, called OpenMP. Note the examples are given in C and Fortran, and both rely heavily on preprocessors/compiler plugins in order to generate the right code. Yes, Fortran is still in heavy use, it seems. And if you learned your Fortran before the 1990s (as I did), you may not even recognize it as the same language.

'Damn Small Linux' is Back - But Bigger
by Peter Reutemann 13 Feb '24

13 Feb '24

'Back in 2006 Slashdot reported on a 50-megabyte "micro" distro called Damn Small Linux. (And in 2012 we wrote that it "rose from the dead" with a new release candidate.) Now Damn Small Linux has been reborn again, according to its developer's web site: Creating the original DSL, a versatile 50MB distribution, was a lot of fun and one of the things I am most proud of as a personal accomplishment. However, as a concept, it was in the right place at the right time, and the computer industry has changed a lot since then. While it would be possible to make a bootable Xwindows 50MB distribution today, it would be missing many drivers and have only a handful of very rudimentary applications. People would find such a distribution a fun toy or something to build upon, but it would not be usable for the average computer user out of the gate.... The new goal of DSL is to pack as much usable desktop distribution into an image small enough to fit on a single CD, or a hard limit of 700MB. This project is meant to service older computers and have them continue to be useful far into the future. Such a notion sits well with my values. I think of this project as my way of keeping otherwise usable hardware out of landfills. As with most things in the GNU/Linux community, this project continues to stand on the shoulders of giants. I am just one guy without a CS degree, so for now, this project is based on antiX 23 i386... a fantastic distribution that I think shares much of the same spirit as the original DSL project. AntiX shares pedigree with MEPIS and also leans heavily on the geniuses at Debian. The blog It's FOSS News describes it as "a unique experience in a sea of Debian-based and Fedora-based distros." It is offered with two window managers, Fluxbox and JWM, with apt being fully enabled by default for easy package installations... At the time of writing, only the Alpha ISOs were made available on the official downloads page. It is only a matter of time before we get a stable release.' -- source: https://linux.slashdot.org/story/24/02/11/2049252 I actually used DSL back in the day...

Mozilla's Abandoned Web Engine 'Servo' is Rebooting in 2024
by Peter Reutemann 12 Feb '24

'Remember "Servo," Mozilla's "next-generation browser engine," focused on performance and robustness? "The developers of Servo are starting 2024 by going all in..." reports It's FOSS News, citing a social media post from FOSDEM. "[T]he Servo Project team were there showing off the work done so far." If you were not familiar, Servo is an experimental browser engine that leverages the power of Rust to provide a memory-safe and modular experience that is highly adaptable. After Mozilla created Servo back in 2012 as a research project, it saw its share of ups and downs over the years, with it making a comeback in 2023; thanks to a fresh approach by the developers on how Servo should move forward. Even though there are plenty of open source Chrome alternatives, with this, there's a chance that we will get some really cool options based on Servo that just might give Blink and Gecko a run for the money! Just a few months back, in September 2023, after The Servo Project officially joined Linux Foundation Europe, the existing contributors from Igalia stepped up their game by taking over the project maintenance. To complement that, at Open Source Summit Europe last year, Manuel Rego from Igalia shared some really useful insights when he presented. He showcased stuff like the WebGL support, cross-platform support including mobile support for Android and Linux, among other things. They have experimented with Servo for embedded applications use-cases (like running it on Raspberry Pi), and have plans to make advances on it. As far as I can see, it looks like, Servo is faster for Raspberry Pi compared to Chromium. You can explore more such demos on Servo's demo webpage. 2024's roadmap includes "Initial Android support, that will see Servo being made to build on modern Android versions," according to the article, "with the developers publishing nightly APKs on the official website some time in the future." One fun fact? "Even though Mozilla dropped the experimental project, Firefox still utilizes some servo components in the browser" Another FOSDOM update from social media: "Thunderbird is also embracing Rust."' -- source: https://news.slashdot.org/story/24/02/11/2024233 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/

ANZ Bank Tries GitHub Copilot, Likes What It Sees
by Lawrence D'Oliveiro 11 Feb '24

11 Feb '24

ANZ Bank tried a study with its in-house Python programmers <https://www.theregister.com/2024/02/10/anz_bank_github_copilot/>, and found "The group that had access to GitHub Copilot was able to complete their tasks 42.36 percent faster than the control group participants," the report says. "...The code produced by Copilot participants contained fewer code smells and bugs on average, meaning it would be more maintainable and less likely to break in production." In terms of code security, they didn’t find that Copilot helped, but neither did it make things worse. But then, these were relatively simple programming exercises. The report also cites another study which found that AI assistance is leading to lower code quality.

Mozilla Names New CEO as It Pivots To Data Privacy
by Peter Reutemann 09 Feb '24

09 Feb '24

'Mozilla, which manages the open-source Firefox browser, announced today that Mitchell Baker is stepping down as CEO to focus on AI and internet safety as chair of the nonprofit foundation. Laura Chambers, a Mozilla board member and entrepreneur with experience at Airbnb, PayPal, and eBay, will step in as interim CEO to run operations until a permanent replacement is found. Fortune: Baker, a Silicon Valley pioneer who co-founded the Mozilla Project, says it was her decision to step down as CEO, adding that the move is motivated by a sense of urgency over the current state of the internet and public trust. "We want to offer an alternative for people to have better products," says Baker, who wants to draw more attention to policies, products and processes to challenge business models built on fueling outrage. "What are the connections between this global malaise and how humans are engaging with each other and technology?" Chambers says she plans to focus on building out new products that address growing privacy concerns while actively looking for a full-time CEO. Prior to being recruited to the Mozilla board three years ago, Chambers says she was feeling "pretty disillusioned" about society because of the influence of money in politics and the growing power of the tech giants. "I was confused about what to do and this felt like a genuine way to make an impact." Chambers says she won't be seeking a permanent CEO role because she plans to move back to Australia later this year for family reasons. "I think this is an example of Mozilla doing the right role modelling in how to manage a succession," says Chambers.

Critical Vulnerability Affecting Most Linux Distros Allows For Bootkits
by Peter Reutemann 08 Feb '24

08 Feb '24

'Linux developers are in the process of patching a high-severity vulnerability that, in certain cases, allows the installation of malware that runs at the firmware level, giving infections access to the deepest parts of a device where they're hard to detect or remove. ArsTechnica: The vulnerability resides in shim, which in the context of Linux is a small component that runs in the firmware early in the boot process before the operating system has started. More specifically, the shim accompanying virtually all Linux distributions plays a crucial role in secure boot, a protection built into most modern computing devices to ensure every link in the boot process comes from a verified, trusted supplier. Successful exploitation of the vulnerability allows attackers to neutralize this mechanism by executing malicious firmware at the earliest stages of the boot process before the Unified Extensible Firmware Interface firmware has loaded and handed off control to the operating system. The vulnerability, tracked as CVE-2023-40547, is what's known as a buffer overflow, a coding bug that allows attackers to execute code of their choice. It resides in a part of the shim that processes booting up from a central server on a network using the same HTTP that the the web is based on. Attackers can exploit the code-execution vulnerability in various scenarios, virtually all following some form of successful compromise of either the targeted device or the server or network the device boots from. "An attacker would need to be able to coerce a system into booting from HTTP if it's not already doing so, and either be in a position to run the HTTP server in question or MITM traffic to it," Matthew Garrett, a security developer and one of the original shim authors, wrote in an online interview. "An attacker (physically present or who has already compromised root on the system) could use this to subvert secure boot (add a new boot entry to a server they control, compromise shim, execute arbitrary code)."' -- source: https://linux.slashdot.org/story/24/02/07/1749248 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/
