- [$] Kernel hackers at Cauldron, 2025 edition
The GNU Tools Cauldron is almost entirely focused on user-space tools, butkernel developers need a solid toolchain too. In what appears to be adeveloping tradition (started in 2024),some kernel developers attended the 2025 Cauldron for thesecond year in a row to discuss their needs with the assembled toolchaindevelopers. Topics covered in this year's gathering include Rust, betterBPF typeformat (BTF) support, SFrame, and more.

- Alpine Linux plans /usr merge
The Alpine Linux project has announcedplans to change its base filesystem hierarchy:
In the future, /lib, /bin, and /sbinwill be symbolic links to their /usr counterparts, and every packageshall be installed under the /usr paths. For now,/usr/bin and /usr/sbin will continue to be independent paths,but that might change if the Filesystem Hierarchy Standard (FHS) getsupdated.
The merge will take place in the upcoming Alpine 3.23 releaseplanned for November; non-merged systems will be consideredunsupported when 3.22 is at its end of life in May 2027.
- [$] Fedora floats AI-assisted contributions policy
The Fedora Council began a process to create a policy on AI-assistedcontributions in 2024, starting with a survey to ask the communityits opinions about AI and using AI technologies in Fedora. OnSeptember 25, Jason Brooks publisheda draft policy for discussion; so far, in keeping with the spirit ofcompromise, it has something to make everyone unhappy. For some it istoo AI-friendly, while others have complained that it holds Fedoraback from experimenting with AI tooling.
- Security updates for Wednesday
Security updates have been issued by AlmaLinux (kernel, kernel-rt, mysql:8.0, and openssh), Debian (libcommons-lang-java, libcommons-lang3-java, libcpanel-json-xs-perl, libjson-xs-perl, libxml2, open-vm-tools, and u-boot), Fedora (bird, dnsdist, mapserver, ntpd-rs, python-nh3, and rust-ammonia), Oracle (kernel and mysql:8.0), Red Hat (cups, postgresql:12, and postgresql:13), SUSE (cJSON-devel, gimp, kernel-devel, kubecolor, open-vm-tools, openssl-1_1, openssl-3, and ruby3.4-rubygem-rack), and Ubuntu (linux-azure-5.15 and openssl, openssl1.0).
- OpenSUSE Leap 16 released
The openSUSELeap 16 release is now available.
This major version update of our fixed-release community-Linux distribution has a fresh software stack and introduces an unmatched maintenance- and security-support cycle, a new installer and simplified migration options.
See our look at this release for moreinformation.
- Radicle 1.5.0 released
Version 1.5.0of the Radicle peer-to-peer Git collaboration platform has beenreleased. This release includes better support for bare repositories,structured logging, and improvements in the output of rad patchshow:
The previous output would differentiate "updates", where the originalauthor creates a new revision, and "revisions", where another authorcreates a revision. This could be confusing since updates are alsorevisions. Instead, the output shows a timeline of the root of thepatch and each new revision, without any differentiation. The revisionidentifiers, head commit of the revision, and author are still printedas per usual.

- [$] Linting Rust code in the kernel
Klint is a Rust compiler extensiondeveloped by Gary Guo to run somekernel-specific lint rules, which may also be useful for embedded systemdevelopment. He spoke about hisrecent work on the project atKangrejos 2025. The next day, Alejandra Gonzálezled a discussion about Rust's normal linter,Clippy. The two tools offer complementary approaches to analyzing Rustkernel code, although both need some additional direction and support fromkernel developers to reach their full potential.
- Linux Foundation Welcomes Newton: The Next Open Physics Engine for Robotics
Simulating physics is central to robotics: before a robot ever moves in the real world, much of its learning, testing, and control happens in a virtual environment. But traditional simulators often struggle to match real-world physical complexity, especially where contact, friction, deformable materials, and unpredictable surfaces are involved. That discrepancy is known as the sim-to-real gap, and it’s one of the biggest hurdles in robotics and embodied AI... the Linux Foundation announced that it is contributing Newton, a next-generation, GPU-accelerated physics engine, as a fully open, community-governed project. This move aims to accelerate robotics research, reduce barriers to entry, and ensure long-term sustainability under neutral governance.

- Walmart To Deploy Sensors To Track 90 Million Grocery Pallets by Next Year
Walmart plans to deploy sensors across its 4,600 US stores by the end of 2026 to track 90 million pallets of groceries shipped annually [Editor's note: non-paywalled source]. The retailer and technology vendor Wiliot announced the expansion Thursday. The sensors will monitor the location, condition and temperature of perishables as they move from warehouses to stores. Walmart started testing Wiliot's sensors at a Texas warehouse in 2023 and has expanded to 500 locations. The full rollout will cover the retailer's US store network and 40 distribution centers. The microchips measure 0.7 square millimeters and are embedded in shipping labels. They use Bluetooth to transmit real-time data about pallets. Walmart previously relied on manual scanning and paper checks by employees. The Arkansas-based company employs 2.1 million people but increased revenues by $150 billion over five years without adding workers. Walmart accounts for more than a fifth of US grocery sales.

- Linkedin CEO Says Fancy Degrees Will Matter Less in the Future of Work
Top college degrees may no longer provide the edge they once did in the job market, per LinkedIn CEO Ryan Roslansky. "I think the mindset shift is probably the most exciting thing because my guess is that the future of work belongs not anymore to the people that have the fanciest degrees or went to the best colleges, but to the people who are adaptable, forward thinking, ready to learn, and ready to embrace these tools," Roslansky said. "It really kind of opens up the playing field in a way that I think we've never seen before." A 2024 Microsoft survey found 71% of business leaders would choose less-experienced candidates with AI skills over experienced candidates without them. LinkedIn data showed job postings requiring AI literacy increased about 70% year-over-year. Roslansky said AI will not replace humans but people who embrace AI will replace those who don't.

- Earth Is Getting Darker, Literally, and Scientists Are Trying To Find Out Why
An anonymous reader shares a report: It's not the vibes; Earth is literally getting darker. Scientists have discovered that our planet has been reflecting less light in both hemispheres, with a more pronounced darkening in the Northern hemisphere, according to a study published on Monday in Proceedings of the National Academy of Sciences. The new trend upends longstanding symmetry in the surface albedo, or reflectivity, of the Northern and Southern hemispheres. In other words, clouds circulate in a way that equalizes hemispheric differences, such as the uneven distribution of land, so that the albedos roughly match -- though nobody knows why. "There are all kinds of things that people have noticed in observations and simulations that tend to suggest that you have this hemispheric symmetry as a kind of fundamental property of the climate system, but nobody's really come up with a theoretical framework or explanation for it," said Norman Loeb, a physical scientist at NASA's Langley Research Center, who led the new study. "It's always been something that we've observed, but we haven't really explained it fully." To study this mystery, Loeb and his colleagues analyzed 24 years of observations captured since 2000 by the Clouds and the Earth's Radiant Energy System (CERES), a network of instruments placed on several NOAA and NASA satellites. Instead of an explanation for the strange symmetry, the results revealed an emerging asymmetry in hemispheric albedo; though both hemispheres are darkening, the Northern hemisphere shows more pronounced changes which challenges "the hypothesis that hemispheric symmetry in albedo is a fundamental property of Earth," according to the study.

- Japan is Running Out of Its Favorite Beer After Ransomware Attack
Japan is just a few days away from running out of Asahi Super Dry as the producer of the nation's most popular beer wrestles with a devastating cyber attack that has shut down its domestic breweries. From a report: The vast majority of Asahi Group's 30 factories in Japan have not operated since Monday after the attack disabled its ordering and delivery system, the company said. Retailers are already expecting empty shelves as the outage stretches into its fourth day with no clear timeline for factories recommencing operations. Super Dry could also run out at izakaya pubs, which rely on draught and bottles. Lawson, one of Japan's big convenience stores, said in a statement that it stocks many Asahi Group products and "it is possible that some of these products may become increasingly out of stock from tomorrow onwards." "This is having an impact on everyone," said an executive at another of Japan's major retailers. "I think we will run out of products soon. When it comes to Super Dry, I think we'll run out in two or three days at supermarkets and Asahi's food products within a week or so."

- Trust in Media at New Low of 28% in US
Americans' confidence in the mass media has edged down to a new low, with just 28% expressing a "great deal" or "fair amount" of trust in newspapers, television and radio to report the news fully, accurately and fairly, according to Gallup. From the report: This is down from 31% last year and 40% five years ago. Meanwhile, seven in 10 U.S. adults now say they have "not very much" confidence (36%) or "none at all" (34%). When Gallup began measuring trust in the news media in the 1970s, between 68% and 72% of Americans expressed confidence in reporting. However, by the next reading in 1997, public confidence had fallen to 53%. Media trust remained just above 50% until it dropped to 44% in 2004, and it has not risen to the majority level since. The highest reading in the past decade was 45% in 2018, which came just two years after confidence had collapsed amid the divisive 2016 presidential campaign.

- Red Hat Investigating Breach Impacting as Many as 28,000 Customers, Including the Navy and Congress
A hacking group claims to have pulled data from a GitLab instance connected to Red Hat's consulting business, scooping up 570 GB of compressed data from 28,000 customers. From a report: The hack was first reported by BleepingComputer and has been confirmed by Red Hat itself. "Red Hat is aware of reports regarding a security incident related to our consulting business and we have initiated necessary remediation steps," Stephanie Wonderlick, Red Hat's VP of communications told 404 Media. A file released by the hackers and viewed by 404 Media suggested that the hacking group may have acquired some data related to about 800 clients, including Vodafone, T-Mobile, the US Navy's Naval Surface Warfare Center, the Federal Aviation Administration, Bank of America, AT&T, the U.S. House of Representatives, and Walmart.

- In a Sea of Tech Talent, Companies Can't Find the Workers They Want
Tech companies are struggling to fill AI-specialized roles despite a surplus of available tech talent. U.S. colleges more than doubled the number of computer science degrees awarded between 2013 and 2022. Major layoffs at Google, Meta, and Amazon flooded the job market. The Bureau of Labor Statistics predicts businesses will employ 6% fewer computer programmers in 2034 than last year. The disconnect stems from companies seeking workers with specific AI expertise. Runway CEO Cristobal Valenzuela estimates only hundreds of people worldwide possess the skills to train complex AI models. His company advertises base salaries up to $490,000 for a director of machine learning. Daniel Park's startup Pickle offers up to $500,000 base salary and expects candidates willing to work seven days a week. The WSJ story includes the example of one James Strawn, who was laid off from Adobe over the summer after 25 years as a senior software quality-assurance engineer. The 55-year-old has had one interview since his layoff. Matt Massucci, CEO of recruiting firm Hirewell, told the publication companies can automate some low-level engineering tasks and redirect that money to high-end talent.

- Japan Saw Record Number Treated For Heatstroke in Hottest-Ever Summer
More than 100,000 people were sent to hospitals due to heatstroke in Japan between May 1 and Sunday, according to preliminary data from the Fire and Disaster Management Agency. Bloomberg, via Japan Times: The number is the most on record, according to NHK. Transport to hospitals of patients linked to heatstroke over the period rose almost 3% to 100,143 from a year earlier as Japan saw its national temperature record broken twice in a matter of days. The country's average temperature during this summer was the highest since the statistic began being compiled in 1898, the nation's weather agency said last month. Heat waves around the world are being made stronger and more deadly due to human-caused climate change. Government officials in August pledged to boost public health protections and encouraged the installation of more air conditioners in school gymnasiums and the use of cooling centers in communal spaces like libraries. New rules came into effect this summer that require employers to take adequate measures to protect workers from extreme temperatures.

- Insurers Are Using Cancer Patients as Leverage
Major health insurers are threatening to drop renowned cancer centers from their networks during contract negotiations, Memorial Sloan Kettering Cancer Center's president and CEO Selwyn M. Vickers and chairman Scott M. Stuart wrote in a story published by WSJ. Memorial Sloan Kettering Cancer Center reported that both Anthem Blue Cross Blue Shield and UnitedHealthcare prepared to terminate network agreements while patients underwent active cancer treatment. FTI Consulting found that 45% of 133 provider-payer disputes in 2024 failed to reach timely agreements. The disruptions have affected tens of thousands of patients. Research published in the Journal of the National Cancer Institute found that care disruptions lead to more advanced-stage diagnoses and worse outcomes. Similar contract disputes involved Mayo Clinic, Johns Hopkins University and University of North Carolina Health. New York lawmakers introduced legislation this year requiring insurers to maintain coverage for cancer patients during negotiations and until treatment concludes. Memorial Sloan Kettering's leadership described the practice as using patients as bargaining chips despite record insurer profits.

- Google Cuts More Than 100 Design-Related Roles In Cloud Unit
Google has laid off over 100 employees in design-related roles, including user experience research and cloud design teams, as part of broader cost-cutting measures to prioritize AI infrastructure. CNBC reports: Earlier this week, the company laid off employees within the cloud unit's "quantitative user experience research" teams and "platform and service experience" teams, as well as some adjacent teams, according to internal documents viewed by CNBC. The roles often focus on using data, surveys and other tools to understand and implement user behaviors that inform product development and design. Google has halved some of the cloud unit's design teams, and many of those affected are U.S.-based roles. Some employees have been given until early December to find a new role within the company.

- Ubuntu Touch 24.04-1.0 released
With Google closing up Android at a rapid pace, theres some renewed interest in mobile platforms that arent either iOS or Android, and one of those is Ubuntu Touch. Its been steadily improving over the years under the stewardship of the UBports Foundation, and today they released Ubuntu Touch 24.04-1.0. Ubuntu Touch 24.04-1.0 is the first release of Ubuntu Touch which is based on Ubuntu 24.04 LTS, a major upgrade from Ubuntu 20.04. This might not be as big compared to our last upgrade from Ubuntu 16.04 to 20.04, but this still brings newer software stack to Ubuntu Touch (such as Qt 5.15). ↫ Ubuntu Touch 24.04-1.0 release announcement In this release, aside from the upgrade to Ubuntu 24.04 LTS, theres now also a light mode for the shell, including experimental support for switching themes on the fly. Applications already supported a light theme since the previous releases, so adding support for it in the main shell is a welcome improvement. Weve also got experimental support for encrypting personal data, which needs to be enabled per device, which I think indicates not all devices support it. On top of that, theres some changes to the phone application, and a slew of smaller fixes and improvements as well. The list of supported devices has grown as well, with the Fairphone 5 as the newcomer this release. The list is still relatively small, but to be fair to the project, it includes a number of popular devices, as well as a few that are still readily available. If you want to opt for running Ubuntu Touch as your smartphone platform, theres definitely plenty of devices to choose from.
- Microsoft conducts Windows reorg that sees core engineering teams back under the same roof as feature experience teams
Microsoft is reorganising the Windows teams. Again. For those unaware, the Windows organization has essentially been split in two since 2018. Teams that work on the core of Windows were moved under Azure, and the rest of the Windows team (those that focused on top level features and user experiences) remained under the Windows org. That is finally changing, with Davuluri saying that the Windows client and server teams are now going to operate under the same roof once again. This change unifies Windows engineering work under a single organization 0 Moving the teams working on Windows client and server together into one organization brings focus to delivering against our priorities.! ↫ Zac Bowden at Windows Central I mean, its obviously far too simplistic to attribute Windows many user-facing problems and failures on something as simple as this particular organisational split, but it sure does feel like it could be a contributing factor. It seems like the core of Windows is mostly fine and working pretty well, while the user experience is the ares that has suffered greatly in recent years, pressured as the Windows team seems to have been to add advertising, monetisation, tons of sometimes dangerous dark patterns, and more. I hope that bringing these two teams back together will eventually lead to an overall improvement of the Windows user experience, and not a deterioration of the core of the platform. In other words, that the core team lifts up the user experience team, instead of the user experience team dragging the core team down. A Windows that takes its users seriously and respects them could be a fine operating system to use, but it reorganisations like this take a long time to have any measurable effect. Of course, it could also just have no effect at all, or perhaps the rot has simply spread too far and wide. In a few years, depressing as it may seem, Windows 11 might be regarded as a highlight.

- The Encore 91 computer system
Have you ever heard of the Encore 91 computer system, developed and built by Encore Computer Corporation? I stumbled upon the name of this system on the website for the Macintosh like virtual window manager (MLVWM), an old X11 window manager designed to copy some of the look and feel of the classic Mac OS, and wanted to know more about it. An old website from what appears to be a reseller of the Encore 91 has a detailed description and sales pitch of the machine still online, and its a great read. The hardware architecture of the Encore 91 series is based on the Motorola high-performance 88100 25MHz RISC processor. A basic system is a highly integrated fully symmetrical single board multiprocessor. The single board includes two or four 88100 processors with supporting cache memory, 16 megabytes of shared main memory, two synchronous SCSI ports, an Ethernet port, 4 asynchronous ports, real-time clocks, timers, interrupts and a VME-64 bus interface. The VME-64 bus provides full compatibility with VME plus enhancements for greater throughput. Shared main memory may be expanded to 272 megabytes (mb) by adding up to four expansion cards. The expansion memory boards have the same high-speed access characteristics as local memory. ↫ Encore computing 91 system The Encore 91 ran a combination of AT8T’s system V.3.2 UNIX and Encore’s POSIX-compliant MicroMPX real-time kernel, and would be followed by machines with more powerful processors in the 88xxx series, as well as machines based on the Alpha architecture. The company also created and sold its own modified RISC architecture, RSX, for which there are still some details available online. Bits and bobs of the company were spun off and sold off, and I dont think much of the original company is still around today. Regardless, its an interesting system with an interesting history, but well most likely never get to see oe in action unless it turns up in some weird corner of the United States where the rare working examples of hardware like this invariably tends to end up.
- Googles Android developer registration requirement will kill F-Droid
The consequences of Google requiring developer certification to install Android applications, even outside of Googles own Play Store, are starting to reverberate. F-Droid, probably the single most popular non-Google application repository for Android, has made it very clear that Googles upcoming requirement is most likely going to mean the end of F-Droid. If it were to be put into effect, the developer registration decree will end the F-Droid project and other free/open-source app distribution sources as we know them today, and the world will be deprived of the safety and security of the catalog of thousands of apps that can be trusted and verified by any and all. F-Droid’s myriad users will be left adrift, with no means to install — or even update their existing installed — applications. ↫ F-Droids blog post A potential loss of F-Droid would be a huge blow to anyone trying to run Android without Googles applications and frameworks installed on their device. Its pretty clear that Google is doing whatever it can to utterly destroy the Android Open Source Project, something Ive been arguing is what the rumours about Google killing AOSP really mean. Why kill AOSP, when you can just make it utterly unusable and completely barren? Sadly, there isnt much F-Droid can do. Theyre proposing regulators the world over look at Googles plans, and hopefully come to the conclusion that theyre anti-competitive. Specifically the European Union and the tools provided by the Digital Markets Act could prove useful here, but in the end, only if the will exists to use them can these tools be used in the first place. Its dark times for the smartphone world right now, especially if you care about consumer rights and open source. iOS has always been deeply anti-consumer, and while the European Union has managed to soften some of the rough edges, nothing much has changed there. Android, on the other hand, had a thriving open source, Google-free community, but decision by decision, Google is beating it into submission and killing it off. The Android of yesteryear doesnt exist anymore, and its making people who used to work on Android back during the good old times extremely sad. Jean-Baptiste Quéru, husband of OSNews amazing and legendary previous managing editor Eugenia Loli-Queru, worded it like this a few days ago: All the tidbits of news about Android make me sad. I used to be part of the Android team. When I worked there, making the application ecosystem as open as the web was a goal. Releasing the Android source code as soon as something hit end-user devices was a goal. Being able to run your own build on actual consumer hardware was a goal. For a while after I left, there continued to be some momentum behind what I had pushed for. But, now, 12 years later, this seems to have all died. I am sad0 ↫ Jean-Baptiste Quéru And so am I. Like any operating system, Android is far from perfect, but it was remarkable just how open it used to be. I guess good things just dont survive once unbridled capitalism hits.
- Unite: a decades-old QNX-inspired hobby operating system
Unite is an operating system in which`everything`is a process, including the things that you normally would expect to be part of the kernel. The hard disk driver is a user process, so is the file system running on top of it. The namespace manager is a user process. The whole thing (in theory, see below) supports network transparency from the ground up, you can use resources of other nodes in the network just as easily as you can use local resources, just prefix them with the node ID. In the late 80’s, early 90’s I had a lot of time on my hands. While living in the Netherlands I’d run into the QNX operating system that was sold locally through a distributor. The distributors brother had need of a 386 version of that OS but Quantum Software, the producers of QNX didn’t want to release a 386 version. So I decided to write my own. ↫ Jacques Mattheij What a great story. Mattheij hasnt done anthing or even looked at the code for this operating system he created in decades, but recently got the urge to fix it up and publish it online for all of us to see. Of course, resurrecting something this old and long untouched required some magic, and theres still a few things which he simply just cant get to work properly. I like how the included copy of vi is broken and adds random bits of garbage to files, and things like the mouse driver dont work because it requires a COM port and the COM ports dont seem to work in an emulated environment. Unite is modeled after QNX, so it uses a microkernel. It uses a stripped-down variant of the MINIX file system, only has one user but that user can run multiple sessions, and theres a basic graphics mode with some goodies. Sadly, the graphics mode is problematic an requires some work to get going, and because youll need the COM ports to work to use it properly its a bit useless anyway at the moment. Regardless, its cool to see people going back to their old work and fixing it up to publish the code online.
- Why was Windows 3.0’s WinHelp called an online help system when it ran offline?
Some time ago, I described Windows 3.0’s WinHelp as “a program for browsing online help files.” But Windows 3.0 predated the Internet, and these help files were available even if the computer was not connected to any other network. How can it be “online”? ↫ Raymond Chen at The Old New Thing I doubt this will be a conceptual problem for many people reading OSNews, but I can definitely understand especially younger people finding this a curious way of looking at the word online!. Youll see the concept of online help! in quite a few systems from the 90s (and possibly earlier), so if youre into retrocomputing you mightve run into it as well.
- Installing Linux on a PC-98 machine
What if you have a PC-98 machine, and you want to run Linux on it, as you do? I mean, CP/M, OS/2, or Windows (2000 and older) might not cut it for you, after all. Well, it turns out that yes, you can run Linux on PC-98 hardware, and thanks to a bunch of work by Nina Kalinina yes, the same person from a few days ago theres now more information gathered in a single place to get you started. Plamo Linux is one of the few Linux distributions to support PC-98 series. Plamo 3.x is the latest distribution that can be installed on PC-9801 and PC-9821 directly. Unfortunately, it is quite old, and is missing lots of useful stuff. This repo is to share a-ha moments and binaries for Plamo on PC-98. ↫ Plamo98 goodies The repository details upgrading! its a bit more involved than plain upgrading, but its not hard Plamo Linux from 3.x to 4, which gives you access to a bunch of things you might want, like GCC 3.3 over 2.95, KDE 3.x, Python 2.3, and more. Theres also custom BusyBox config files, a newer version of make, and a few other goodies and tools you might want to have. Once its all set and done, you can Linux like its 2003 on your PC-98. The number of people to whom this is relevant must be extraorinarily small, but at some point, someone is going to want to do this, only to find this repository of existing work. Weve all been there.
- UNIX99: UNIX for the TI-99/4A
I’ve been working on developing an operating system for the TI-99 for the last 18 months or so. I didn’t intend this—my original plan was to develop enough of the standard C libraries to help with writing cartridge-based and EA5 programs. But that trek led me quickly towards developing an OS. As Unix is by far my preferred OS, this OS is an approximation. Developing an OS within the resources available, particularly the RAM, has been challenging, but also surprisingly doable. ↫ UNIX99 forum announcement post Were looking at a quite capable UNIX for the TI-99, with support for its sound, speech, sprites, and legacy 9918A display modes, GPU-accelerated scrolling, stdio (for text and binary files) and stdin/out/err support, a shell (of course), multiple user support, cooperative tasks support, and a ton more. And remember all of this is running on a machine with a 16-bit processor running at 16MHz and a mere 16KB of RAM. Absolutely wild.
- Another win for the Digital Markets Act: Microsoft gives truly free access to additional year of Windows 10 updates to EU users
A few months ago, Microsoft finally blinked and provided a way for Windows 10 users to gain free! access to the Windows 10 Extended Security Update program. For regular users to gain access to this program, their options are to either pay around $30, pay 1000 Microsoft points, or to sign up for the Windows Backup application to synchronise their settings to Microsoft’s computers (the “cloud”). In other words, in order to get free! access to extended security updates for Windows 10 after the 25 October end-of-support deadline, you have to start using OneDrive, and will have to start paying for additional storage since the base 5GB of OneDrive storage wont be enough for backups. And we all know OneDrive is hell. Thanks to the European Unions Digital Markets Act, though, Microsoft has dropped the OneDrive requirement for users within the European Economic Area (the EU plus Norway, Iceland, and Liechtenstein). Citing the DMA, consumer rights organisations in the EU complained that Microsofts OneDrive requirement was in breach of EU law, and Microsoft has now given in. Of course, dropping the OneDrive requirement only applies to consumers in the EU/EEA; users in places with much weaker consumer protection legislation, like the United States, will not benefit from this move. Consumer rights organisations are lauding Microsofts move, but theyre not entirely satisfied just yet. The main point of contention is that the access to the Extended Security Update program is only valid for one year, which they consider too short. In a letter, Euroconsumers, one of the consumer rights organisations, details this issue. At the same time, several points from our original letter remain relevant. The ESU program is limited to one year, leaving devices that remain fully functional exposed to risk after October 13, 2026. Such a short-term measure falls short of what consumers can reasonably expect for a product that remains widely used and does not align with the spirit of the Digital Content Directive (DCD), nor the EU’s broader sustainable goals. Unlike previous operating system upgrades, which did not typically require new hardware, the move to Windows 11 does. This creates a huge additional burden for consumers, with some estimates suggesting that over 850 million active devices still rely on million Windows 10 and cannot be upgraded due to hardware requirements. By contrast, upgrades from Windows 7 or 8 to Windows 10 did not carry such limitations. ↫ Eurconsumers letter According to the group, the problem is exacerbated by the fact that Microsoft is much more aggressive in phasing out support for Windows 10 than for previous versions of Windows. Windows 10 is being taken behind the shed four years after the launch of Windows 11, while Windows XP and Windows 7 enjoyed 7-8 years. With how many people are still using Windows 10, often with no way to upgrade but buying new hardware, its odd that Microsoft is trying to kill it so quickly. In any event, we can chalk this up as another win for consumers in the European Union, with the Digital Markets Act once again creating better outcomes than in other regions of the world.
- Linux Foundation Welcomes Newton: The Next Open Physics Engine for Robotics
by George Whittaker Introduction
Simulating physics is central to robotics: before a robot ever moves in the real world, much of its learning, testing, and control happens in a virtual environment. But traditional simulators often struggle to match real-world physical complexity, especially where contact, friction, deformable materials, and unpredictable surfaces are involved. That discrepancy is known as the sim-to-real gap, and it’s one of the biggest hurdles in robotics and embodied AI.
On September 29th, the Linux Foundation announced that it is contributing Newton, a next-generation, GPU-accelerated physics engine, as a fully open, community-governed project. This move aims to accelerate robotics research, reduce barriers to entry, and ensure long-term sustainability under neutral governance.
In this article, we’ll unpack what Newton is, how its architecture stands out, the role the Linux Foundation will play, early use cases and challenges, and what this could mean for the future of robotics and simulation.
What Is Newton?
Newton is a physics simulation engine designed specifically for roboticists and simulation researchers who want high fidelity, performance, and extensibility. It was conceived through collaboration among Disney Research, Google DeepMind, and NVIDIA. The recent contribution to the Linux Foundation transforms Newton into an open governance project, inviting broader community collaboration.
Design Goals & Key Features
GPU-accelerated simulation: Newton leverages NVIDIA Warp as its compute backbone, enabling physics computations on GPUs for much higher throughput than traditional CPU-based simulators.
Differentiable physics: Newton allows gradients to be propagated through simulation steps, making it possible to integrate physics into learning pipelines (e.g. backpropagation through control parameters).
Extensible and multi-solver architecture: Users or researchers can plug in custom solvers, mix models (rigid bodies, soft bodies, cloth), and tailor functionality for domain-specific needs.
Interoperability via OpenUSD: Newton builds on OpenUSD (Universal Scene Description) to allow flexible data modeling of robots and environments, and easier integration with asset pipelines.
Compatibility with MuJoCo-Warp: As part of the Newton project, the MuJoCo backbone is adapted (MuJoCo-Warp) for high-performance simulation within Newton’s framework.

- Kernel 6.15.4 Performance Tuned, Networking Polished, Stability Reinforced
by George Whittaker Introduction
In the life cycle of any kernel branch, patch releases, those minor “.x” updates, play a vital role in refining performance, patching regressions, and ironing out rough edges. Kernel 6.15.4 is one such release: it doesn’t bring headline features, but focuses squarely on stabilizing and optimizing the 6.15 series with targeted fixes in performance and networking.
While version 6.15 already introduced several ambitious changes (filesystem improvements, networking enhancements, Rust driver infrastructure, etc.), the 6.15.4 update doubles down on making those changes more robust and efficient. In this article, we'll walk through the most significant improvements, what they mean for systems running 6.15.*, and how to approach updating.
Release Highlights
The official announcement of Kernel 6.15.4 surfaced around late June 2025. The release includes:
A full source tarball (linux-6.15.4.tar.xz) and patches.
Signature verification via PGP for integrity.
A changelog/diff summary comparing 6.15.3 → 6.15.4.
This update is not a major feature expansion; it’s a refinement release targeting performance regressions, network subsystem reliability, and bug fixes that emerged in prior 6.15.* builds.
Performance Enhancements
Because 6.15 already brought several ambitious changes to memory, I/O, scheduler, and mount semantics, many of the improvements in 6.15.4 are about smoothing interactions, avoiding regressions, and reclaiming performance in corner cases. While not all patches are publicly detailed in summaries, we can infer patterns based on what 6.15 introduced and what “performance patches” generally target.
Memory & TLB Optimizations
One often-painful cost in high-performance workloads is flushing translation lookaside buffers (TLBs) too aggressively. Kernel 6.15 had already begun to optimize broadcast TLB invalidation using AMD’s INVLPGB (for remote CPUs) to reduce overhead in multi-CPU environments. In 6.15.4, fixes likely target edge cases or regressions in those mechanisms, ensuring TLB invalidation is more efficient and consistent.
Additionally, various memory management cleanups, object reuse, and page handling improvements tend to appear in patch releases. While not explicitly documented in the public summaries, such fixes help reduce fragmentation, locking contention, and latency in memory allocation.

- Python 3.13.5 Patch Release Packed with Fixes & Stability Boosts
by George Whittaker Introduction
On June 11, 2025, the Python core team released Python 3.13.5, the fifth maintenance update to the 3.13 line. This release is not about flashy new language features, instead, it addresses some pressing regressions and bugs introduced in 3.13.4. The “.5” in the version number signals that this is a corrective, expedited update rather than a feature-driven milestone.
In this article, we’ll explore what motivated 3.13.5, catalog the key fixes, review changes inherited in the 3.13 stream, and discuss whether and how you should upgrade. We’ll also peek at implications for future Python releases.
What Led to 3.13.5 (Release Context)
Python 3.13 — released on October 7, 2024 — introduced several significant enhancements over 3.12, including a revamped interactive shell, experimental support for running without a Global Interpreter Lock (GIL), and preliminary JIT infrastructure.
However, after releasing 3.13.4, the maintainers discovered several serious regressions. Thus, 3.13.5 was accelerated (rather than waiting for the next regular maintenance release) to correct these before they impacted a broader user base. In discussions preceding the release, it was noted the Windows extension module build broke under certain configurations, prompting urgent action.
Because of this, 3.13.5 is a “repair” release — its focus is bug fixes and stability, not new capabilities. Nonetheless, it also inherits and stabilizes many of the improvements introduced earlier in 3.13.
Key Fixes & Corrections
While numerous smaller bugs are resolved in 3.13.5, three corrections stand out as primary drivers for the expedited update:
GH-135151 — Windows extension build failure
Under certain build configurations on Windows (for the non-free-threaded build), compiling extension modules failed. This was traced to the pyconfig.h header inadvertently enabling free-threaded builds. The patch restores proper alignment of configuration macros, ensuring extension builds succeed as before.
GH-135171 — Generator expression TypeError delay
In 3.13.4, generator expressions stopped raising a TypeError early when given a non-iterable. Instead, the error was deferred to the time of first iteration. 3.13.5 restores the earlier behavior of raising the TypeError at creation time when the supplied input is not iterable. This change avoids subtler runtime surprises for developers.

- Denmark’s Strategic Leap Replacing Microsoft Office 365 with LibreOffice for Digital Independence
by George Whittaker
In the summer of 2025, Denmark’s government put forward a major policy change in its digital infrastructure: moving away from using Microsoft Office 365, and in part, open-source its operations with LibreOffice. Below is an original account of what this entails, why it matters, how it’s being done, and what the risks and opportunities are.
What’s Changing and What’s Not
The Danish Ministry of Digital Affairs has committed to replacing Microsoft Office 365 with LibreOffice.
Earlier reports said that Windows would also be entirely swapped-out for Linux, but those reports have since been corrected: Windows will remain in use on many devices for now.
For LibreOffice, the adoption is being phased: about half of the ministry’s employees will begin using LibreOffice (and possibly Linux in some instances) in the summer months; the rest are expected to transition by autumn.
Why Denmark Is Making This MoveDigital Sovereignty & Dependence
A primary driver is the concern over reliance on large foreign tech companies, especially suppliers based outside Europe. By reducing dependency on proprietary software controlled by corporations abroad, Denmark aims to gain more control over its data, security, and updates.
Cost and Licensing
Proprietary software comes with licensing fees, recurring costs, and often tied contracts. Adopting open-source alternatives like LibreOffice can potentially reduce those long-term expenditures.
Security, Transparency, Flexibility
Open-source software tends to allow more auditability, quicker patching, and the ability to adapt tools or software behavior to specific local or regulatory requirements.
Implementation Plan & TimelinePhase What happens Approximate Timing Phase 1 Begin by moving about 50% of Ministry of Digital Affairs employees to LibreOffice (and in selected cases, using Linux tools) Summer 2025 (mid-year) Phase 2 Full transition of the ministry’s office productivity tasks away from Microsoft Office 365 to LibreOffice Autumn 2025
“Full” here is understood in the scope of office productivity tools (word processing, spreadsheets, slides, etc.), not necessarily replacing all legacy systems or moving everything off Windows.
Challenges & Concerns
While the vision is ambitious, there are several hurdles:

- Valve Survey Reveals Slight Retreat in Steam-on-Linux Share
by George Whittaker Introduction
Steam’s monthly Hardware & Software Survey, published by Valve, offers a window into what operating systems, hardware, and software choices its user base is making. It has become a key barometer for understanding trends in PC gaming, especially for less dominant platforms like Linux. The newest data shows that Linux usage among Steam users has edged downward subtly. While the drop is small, it raises interesting questions about momentum, hardware preferences, and what might lie ahead for Linux gaming.
This article dives into the latest numbers, explores what may be pushing them to abandon Steam, and considers what it means for Linux users, developers, and Valve itself.
Recent Figures: What the Data Shows
June 2025 Survey Outcome: In June, Linux’s slice of Steam’s user base stood at 2.57%, down from approximately 2.69% in May — a decrease of 0.12 percentage points.
Year-Over-Year Comparison: Looking back to June 2024, the Linux share was around 2.08%, so even with this recent slip, there’s still an upward trend compared to a year ago.
Distribution Among Linux Users: A significant portion of Linux gamers are using Valve’s own SteamOS Holo (currying sizable usage numbers via Steam Deck and similar devices). In June, roughly one-third of the Linux user group was on SteamOS Holo.
Hardware Insights:
Among Linux users, AMD CPUs dominate: about 69% of Linux gamers use AMD in June.
Contrast that with the Windows-only survey, where Intel still has about 60% CPU share to AMD’s 39%.
Interpreting the Slip: What Might Be Behind the Dip
Though the drop is modest, a number of factors likely combine to produce it. Here are possible causes:
Statistical Noise & Normal Fluctuation Monthly survey results tend to vary a bit, especially for smaller share percentages. A 0.12% decrease could simply be part of the normal ebb and flow.
Sampling and Survey Methodology
Survey participation may shift by region, language, hardware type, or time of year. If fewer Linux users participated in a given month, the percentage would drop even if absolute numbers stayed flat.
Language shifts in Steam’s usage have shown up before; changes in how many users set certain settings or respond could affect results.
Latency or delays in uploading or processing survey data might also contribute to anomalies.

- Qt Creator 17 Ushers in a Fresh Look and Stronger CMake Integration
by George Whittaker
In June 2025, the Qt team officially rolled out Qt Creator 17, marking a notable milestone for developers who rely on this IDE for cross-platform Qt, C++, QML, and Python work. While there are many changes under the hood, two of the spotlighted improvements are its updated default visual style and significant enhancements in how CMake is supported. Below, we’ll explore these in depth, assess their impact, and offer guidance on how to adopt the new features smoothly.
What's New in Qt Creator 17: A Snapshot
Before zooming into the theme and CMake changes, here are some of the broader enhancements in version 17 to set context:
The “2024” theme set (light and dark variants) — which first appeared in earlier versions — becomes the foundational appearance for all new installs.
General polish across the UI: icon refreshes, more consistent spacing, and better contrast.
Projects now bind run configurations more tightly to the build configurations. That means selecting a build (e.g. Debug vs Release) also constrains which run configurations apply.
Upgraded C++ tooling (with LLVM 20.1.3), improved QML formatting options, enhanced Python (pyproject.toml) support, and refinements in version control & analysis tools.
With that backdrop, let’s dive into the theme and CMake changes in more detail.
A Refreshed Visual Identity: Default “2024” ThemesWhat Has Changed
Qt Creator 17 makes the “2024” light and dark themes the standard look & feel for new installations. These themes had been available previously (since Qt Creator 15) but in this version become the out-of-the-box configuration.
Other visual adjustments accompany the theme change:
Icons throughout the IDE have been reviewed and updated so they align better with the new theme style.
UI consistency is improved: spacing, contrast, and alignment between interface elements have been refined so that the environment feels more cohesive.
Why These Changes Matter
A theme isn't just aesthetics. The look and feel of an IDE affect user comfort, readability, efficiency, and even fatigue. Some benefits include:
Improved clarity for long coding sessions: better contrast helps in low-ambient light or for users with visual sensitivity.
Consistency across elements: less jarring visual transitions when switching between parts of the interface or when using external themes/plugins.
Reduced setup friction: since the “2024” theme is now default, many users won’t need to hunt down or tweak theme settings just to get a modern, usable look.

- Windows 11 Powers Up WSL: How GPU Acceleration & Kernel Upgrades Change the Game
by George Whittaker Introduction
Windows Subsystem for Linux (WSL) has gradually become one of Microsoft’s key bridges for developers, data scientists, and power users who need Linux compatibility without leaving the Windows environment. Over recent versions, WSL2 brought major improvements: a real Linux kernel running in a lightweight virtualized environment, much better filesystem behavior, nearly full system-call compatibility, etc. However, until recently, certain high-performance workloads, GPU computing, video encoding/decoding, and very up-to-date kernel features, were either limited, inefficient, or unavailable.
In Windows 11, Microsoft has taken bold strides to remove many of these bottlenecks. Two of the most significant enhancements are:
The ability for WSL to tap into the GPU for acceleration (compute, video hardware offload, etc.), reducing reliance on CPU where the GPU is much more suited.
More seamless Linux kernel upgrades, allowing users to run newer kernel versions inside WSL2, bringing performance, driver, and feature improvements faster.
This article walks through each thing in detail: what has changed, why it matters, how to use it, what limitations still exist, and how these developments shift what’s possible with WSL on Windows 11.
What WSL Was, and Where It Needed Improvement
Before diving into recent changes, it helps to understand what WSL (especially WSL2) already provided, and where it lagged.
WSL1: Early versions translated Linux system calls to Windows equivalents. Good for basic command-line tools, scripts, but limited in compatibility with certain networking, kernel module, filesystem, and performance-sensitive tasks.
WSL2: Introduced a real Linux kernel inside a lightweight VM (Hyper-V or a similar backend), better system-call compatibility, better performance especially for Linux tools, and much improved behavior for things like Docker, compiling, etc. Still, heavy workloads (e.g. ML training, video encoding, hardware-accelerated graphics) were constrained by CPU support, lack of passthrough of GPU features, older kernels, etc.
So developers were pushing Microsoft to allow more direct access to GPU functionality (CUDA, DirectML, video decoding), and to speed up how kernel updates reach users.
GPU Acceleration in WSL on Windows 11: What It Means
GPU acceleration here refers to WSL’s ability to offload certain computation or video tasks from the CPU to the GPU, enabling faster, more efficient execution. This includes:
Compute workloads - frameworks like CUDA (for NVIDIA), DirectML, etc., so that things like deep learning, scientific computing, data-parallel tasks run much faster. Microsoft now supports running NVIDIA CUDA inside WSL to accelerate ML libraries like PyTorch, TensorFlow.

- Harnessing GitOps on Linux for Seamless, Git-First Infrastructure Management
by George Whittaker Introduction
Imagine a world where every server, application, and network configuration is meticulously orchestrated via Git, where updates, audits, and recoveries happen with a single commit. This is the realm GitOps unlocks, especially potent when paired with the versatility of Linux environments. In this article, we'll dive deep into how Git-driven workflows can transform the way you manage Linux infrastructure, offering clarity, control, and confidence in every change.
GitOps Demystified: A New Infrastructure Paradigm
GitOps isn't just a catchy buzzword, it's a methodical rethink of how infrastructure should be managed.
It treats Git as the definitive blueprint for your live systems, everything from server settings to application deployments is declared, versioned, and stored in repositories.
With Git as the single source of truth, every adjustment is tracked, reversible, and auditable, turning ops into a transparent, code-centric process.
Beyond simple CI/CD, GitOps introduces a continuous reconciliation model: specialized agents continuously compare the actual state of systems against the desired state in Git and correct any discrepancies automatically.
Why Linux and GitOps Are a Natural Pair
Linux stands at the heart of infrastructure, servers, containers, edge systems, you name it. When GitOps is layered onto that:
You'll leverage Linux’s scripting capabilities (like bash) to craft powerful, domain-specific automation that dovetails perfectly with GitOps agents.
The transparency of Git coupled with Linux’s flexible architecture simplifies debugging, auditing, and recovery.
The combination gives infrastructure teams the agility to iterate faster while keeping control rigorous and secure.
Architecting GitOps Pipelines for Linux EnvironmentsStructuring Repositories Deliberately
A well-organized Git setup is crucial:
Use separate repositories or disciplined directory structures for:
Infrastructure modules (e.g., Terraform, networking, VMs),
Platform components (monitoring, ingress controllers, certificates),
Application-level configurations (Helm overrides, container versions).
This separation helps ensure access controls align with responsibilities and limits risks from misconfiguration or accidental cross-impact.

- How DevOps Teams Are Redefining Reliability with NixOS and OSTree-Powered Linux
by George Whittaker
This article explores how modern DevOps teams are redefining stability and reproducibility in production environments by embracing truly unchangeable operating systems. It delves into how NixOS’s declarative configuration model and OSTree’s atomic update mechanisms open the door to systems that are both resilient and transparent. We'll explain the advantages, technologies, comparisons, and real-world use cases fueling this shift.
The Paradigm Shift: From Mutable Chaos to Immutable Assurance
Why the change happened: The traditional model, logging into servers, tweaking packages, and patching in place, has led to unpredictable environments, elusive bugs, “snowflake” systems, and configuration drift as environments diverged over time. Immutable infrastructure treats machines like fungible artifacts: if you need change, you don’t fix the running system, you replace it.
Key benefits:
Reliability at scale: Automated, reproducible deployments, no divergence across servers.
Simplified rolling back: If something breaks, spin up the previous, working version.
Security by design: Core systems are read-only, reducing the attack surface.
Immutable Foundations in ActionNixOS: The Declarative, Version-Controlled Linux
How it works: System configuration, including packages, services, kernels, is expressed in the Nix language in a config file. Rebuilding produces a new system “generation,” which can be booted or rolled back.
Why DevOps teams love it:
Reproducibility: Exact environments can be rebuilt from config files, promoting parity across development, CI, and production.
Speed and consistency gains: In one fintech case, switching to NixOS reduced deployment times by over 50 percent, erased environment-related incidents, shrank container sizes by 70%, and cut onboarding time dramatically.
Edge readiness: Ideal for remote systems or stateless servers rebuilt nightly to ensure fleet consistency with easy rollback.
Personalization meets immutability: With tools like Home Manager, even user-specific configurations (like dotfiles or shell preferences) can be managed declaratively, and consistently reproduced across machines.

- From Novice to Pro: Mastering Lightweight Linux for Your Kubernetes Projects
by George Whittaker Introduction: Why Lightweight Matters for Kubernetes Devs
When running Kubernetes clusters for development, the operating system’s footprint can make or break performance and agility. Heavy, general-purpose Linux distributions waste memory and CPU cycles on components you’ll never use, while lightweight, container-focused distros keep your nodes lean and optimized. For developers experimenting with k3s, MicroK8s, or full-blown Kubernetes clusters, lightweight Linux offers faster spin-ups, lower overhead, and environments that better simulate production-grade setups.
In this guide, we’ll take a look at the best lightweight Linux options for Kubernetes developers, compare their strengths, and walk through code examples for quick setup. Whether you’re spinning up a local test cluster or building a scalable dev lab, this breakdown will help you pick the right base OS and make the most of your Kubernetes workflow.
Key Considerations for Dev-Focused Kubernetes Nodes
Before diving into individual distros, it’s important to understand what really matters when pairing Linux with Kubernetes:
Minimal Resource Usage: A slim OS footprint leaves more CPU and RAM for pods and workloads.
Container Runtime Compatibility: Built-in or easy-to-install support for containerd, CRI-O, or Docker ensures smooth cluster bootstrapping.
Init System Support: Compatibility with systemd or OpenRC impacts how Kubernetes services are managed.
Immutable vs. Mutable: Immutable systems like Fedora CoreOS or Talos enhance reliability but restrict tinkering, while Alpine and Ubuntu Core offer more flexibility for on-the-fly customization.
Developer Friendliness: A distro should integrate seamlessly with kubectl, Helm, CI/CD agents, and debugging workflows.
