Kotaku reports: r/opensource, Reddit's primary "subreddit for everything open source related," has banned all AI-assisted and AI-related projects.... As reported by The Verge, the subreddit's October 24 post, titled "Your tokens aren't valuable: No more AI," features four new main rules: all projects must now be at least "1 year old," have "multiple contributors," be posted by someone who must "speak English," and cannot be "made by" or "intended for" AI... [T]he ban on AI is simple; as the subreddit's moderators explain, "AI, as it exists today, is incongruent to this Open Source community." Unsurprisingly, this is the part that's upset the majority of the users in the thread....

[T]he moderator who posted the new guidelines stated in a separate comment that the overwhelmingly negative response is due to "some guy on twitter claiming to be alternative news" who posted an "opinionated editorial pointing hundreds of people to the thread." Given the timing of when the thread was posted, alongside the fact that the X post in question mentions "the Linux kernel," they are presumably referring to this post by The Lunduke Journal. The moderator may be correct, as almost all of the top comments on the post are from users who have never posted in r/opensource before.
The use of AI "doesn't change whether something is open source or not," complained one commenter, who added "I guess Linux is no longer allowed here? Linus uses AI for kernel development now."

The moderator has since updated their post to acknowledge that Redditors have now already created a rival community called r/OpenSourceAIAllowed — plus three more alternatives:

• r/TrueOpenSource
• r/OpenSourceWare
• r/ActuallyOpenSource

UPDATE (10/26): Monday saw a new comment from the moderator stressing that "Adjustments will be made."

"Linux is not, nor could conceivably ever be banned. Interpreting any set of rules as such is simply bad faith. Someone's pet project pumped out in two claude code session limits will not be welcome. The line is somewhere between those, and it will likely move over time from continuous feedback.

"We will cater to humans, and as many and as inclusively as possible. No rule will ever target or favor any ethnicity or social strata."

The problem? Understanding how AI coding agents interact with the software you build. "Whether you're maintaining an SDK, building a command-line interface, or publishing an MCP server or skills... you need to understand whether agents can discover and use what you ship, and what your team can change."

Results can vary, and configurations keep changing, with behaviors influenced by everything from custom instructions and MCP servers to skills and plugins. So after a year of development Microsoft has created Scope, "an open-source platform built on Kubernetes for turning those interactions into evidence product teams can act on."

Details are available on... the Microsoft open source blog: Available under the MIT License, Scope supports a continuous Developer Agent Experience (DevAx) learning loop grounded in repeatable experiments.

The Azure Cosmos DB team's experience shows what that loop can deliver... "The evaluations led to 20 Agent Kit issues and 27 documentation issues resolved," [says Jay Gordon, Senior Program Manager, Azure Cosmos DB]... These results connect evaluation to decisions a product team can make: which documentation needs clarification, where tooling needs a fix, and whether an update changes agent behavior.... [The gains] demonstrate how targeted changes, informed by observed behavior, can improve the way agents use a product.

For more on the shift from building for human developers to supporting agents, watch Your Product Was Built for Humans. Is It Ready for Agents? or join us at AI DevCon NYC conference in November.
Scope surfaces everything from incorrect assumptions in documentation (or recurring missed instructions) to whether agents select the intended SDK, initialize it correctly, and use its APIs, leading to clearer descriptions for command-line tool and more actionable errors.

Microsoft's open source blog also explains why AI agent evaluation needs an open-source foundation: The challenges behind agent experience aren't unique to one product or organization. SDK maintainers, tool authors, researchers, and agent developers are all asking how agents behave and what helps them succeed. No single team can represent every language, workflow, or integration. An open project can bring more scenarios, more failure cases, and more viewpoints into the evaluation process... Opening Scope's execution and evaluation code gives contributors a way to question the methods, investigate unexpected results, and improve the evaluation itself. A shared foundation also reduces duplicated infrastructure. Agent integrations, reusable criteria, and trace-analysis improvements can help other teams study their own products without rebuilding the same machinery. The goal isn't one universal benchmark or definition of success. It's a common starting point that teams can adapt to their needs.

The MIT License lets teams use and extend Scope, while self-managed deployments let them evaluate private workloads without publishing their code or run data.... Scope streams activity as the agent works and retains interactions and workspace snapshots for later review. Your team can follow tool calls, inspect generated files, and connect a failed requirement to the steps that preceded it. Those traces provide observable evidence of what the agent did, helping turn a failure into a concrete documentation, SDK, or tooling improvement.

An anonymous reader quotes a report from ZDNet: The Netherlands' Tax and Customs Administration has abandoned its planned Microsoft 365 public-cloud rollout. Why? The reasons were clear at the Open Source Summit Europe conference, where the Linux Foundation (LF) released the 2026 State of Open Source in Europe. In it, the nonprofit, pro-open-source organization revealed that 94% of European Union (EU) organizations say digital sovereignty is important, with 61% considering it very important. As Thierry Carrez, the Linux Foundation Europe GM, said in his keynote, "Europe has clearly heard the message on digital sovereignty."

In an interview onstage at the summit, Nithya Ruff, chair of the LF board, added that it's not just Europe: "Digital sovereignty is a need that the entire world feels, whether it's Sierra Leone or the US or China." It's not just the Dutch tax collectors, though. The Netherlands is also exploring switching from Windows and proprietary software to Linux and open-source programs across the board. [...] The Netherlands had planned to switch to Microsoft 365 in 2025. The idea then was to complete the rollout by the end of 2026. About 5,000 employees had already migrated when the Dutch Advisory Council on ICT Assessment recommended reversing the public-cloud rollout in June. The government paused the plan in July; the latest announcement replaces that rollout with an on-premises/open-source approach.

The Tax and Customs Administration isn't replacing all of Microsoft Office with a single open-source suite, at least not yet. Instead, the government will keep the existing Microsoft software for now. Looking ahead, State Secretary for Finance Eelco Eerenberg set out the replacement timetable in a letter to Parliament: "In 2027, the provision for mail and calendar will be realized on-premises. Later in 2027 and 2028, European open-source solutions for personal storage and collaboration will follow. This allows us to work toward a sustainable and more autonomous solution for these functionalities." [...] For now, the on-premises email/calendar environment will still use Microsoft software, including Outlook. The open-source portion concerns personal storage and collaboration, not a wholesale replacement of Word, Excel, PowerPoint, or the entire desktop environment. As for why the Netherlands pulled back, the ICT assessment found serious concerns over "information security, information processing and future-proofing." Key issues included routing confidential documents through American servers, relying on standard Microsoft encryption rather than Double Key Encryption, and inadequate end-to-end encryption for Teams calls. The assessment also identified "vendor lock-in, reduced flexibility, concerns about digital sovereignty, and the absence of an adequate exit strategy" as dealbreakers.

ZDNet notes that other Dutch government agencies are developing an open-source alternative called DAWO (Digital Autonomous Work Environment for Government), which would begin by replacing Windows with the Linux distribution NixOS.

The blog It's FOSS reports: You already know that Canonical has been selectively replacing Ubuntu's C-based system components with Rust-written equivalents that don't compromise in terms of functionality, most of the time. Now it looks like the distro's OpenPGP implementation is next, with Sequoia PGP coming preinstalled in Ubuntu 26.10. Canonical wants it to eventually replace GnuPG [the dominant Linux implementation of PGP, written in C] as the default toolchain, though that switch has not happened yet... [The Ubuntu 26.10 release notes say Sequoia PGP's default status will be a future goal...]

[Sequoia PGP] was started in 2017 by three former GnuPG developers who chose to build a new OpenPGP implementation in Rust rather than keep evolving GnuPG's existing codebase. Sequoia PGP is designed as a library that other software can use directly, rather than a standalone command-line tool. sq sits on top of that for encryption, decryption, signing, and key management, and sqv handles signature verification, filling in for gpg and gpgv in GnuPG.

Sequoia also implements RFC 9580, the 2024 revision of the OpenPGP standard, whereas GnuPG has continued from the RFC 4880 branch, pursuing its own newer extensions and the LibrePGP specification rather than adopting RFC 9580 as its primary standard.
From the It's FOSS Weekly newsletter, which also notes that the founder of the It's FOSS blog has also created a Linux-themed game called TUXDLE — a variation on Wordle where all the answers are Linux terms.

Mistral has unveiled Mistral Large 4, or "le Chonk," a 1-trillion-parameter model that it says is the strongest open-weight AI model developed outside China by a wide margin. The model is entering preview for developers, cybersecurity teams and governments before a broader release later this month. CNBC reports: ML4 was trained on 4,000 Nvidia Grace Blackwell GPUs over two months that were deployed in Mistral's own data centers in Europe. When its core parameters are released, ML4 will rank among the top open-weight models globally on aggregate benchmark performance, Mistral said in a statement. The company added that ML4 was the strongest open-weight model developed outside China by a "substantial margin." The new model still lags behind the frontier in areas such as coding.

"The model capabilities will further improve as we scale up our training capacity, following our Series D fundraise," said Guillaume Lample, co-founder and chief scientist of Mistral. "Further, the cyber defense capabilities will enable enterprises and governments to defend themselves against threat actors that are jailbreaking closed models to perform cyber attacks," he added.

A new open-source command-line tool called RemoveMacAI lets macOS 27 users disable Apple Intelligence and reclaim around 12GB or more of storage. MacRumors reports: In macOS 27, Apple removed the toggle to disable Apple Intelligence wholesale, and simply disabling individual features doesn't remove the models from your Mac's drive. As explained by the developer, RemoveMacAI gets around this by using a configuration profile to switch off Apple's own asset management service and remove the models.

It then configures the system so attempts to download the removed models are redirected to a closed local port, preventing them from immediately coming back. And it does all this without disabling System Integrity Protection (SIP) or manually deleting files from protected system locations, unlike some older tools have. The tool can free up roughly 12GB of space depending on which models are present on your Mac. That said, some users are reporting cases of Apple Intelligence models having taken up a lot more space, which they've now reclaimed.

- In 2022 Altair Engineering open sourced "OpenRadioss", an industry-leading finite element solver under the GNU AGPL License, reports Phoronix.

- Siemens acquired Altair Engineering last year

- Siemens closes access to OpenRadioss.

"Siemens didn't just end the project but they shutdown the GitHub repository that hosted the open-source code and removed other resources that had built around it," writes Phoronix, before announcing a new open-source community fork: Radioss has been an industry-leading solver for analyzing crashes, blasts, and other purposes. Altair creating OpenRadioss was a huge milestone for the technical computing industry. It also had other effects like for myself in finally being able to benchmark with this (Open)Radioss code for CPU performance testing compared to the expensive licensing on Radioss itself...

Siemens argues the OpenRadioss closure is for consolidating efforts:

"After four years of successful community-driven research, Siemens is entering a new chapter for the Radioss solver. To accelerate innovation and provide the robust support our global users require for production-grade simulation, we are consolidating our efforts."
It was Brian Clemens. founder/VP Rocky Linux and the Rocky Enterprise Software Foundation who launched the community fork of OpenRadioss — to be called OpenCourant. Its web site announces they'll be "carrying forward the OpenRadioss code base under the GNU AGPL, in the open, where it belongs."

Phoronix writes in a follow-up: OpenCourant is based on the last publicly known open-source OpenRadioss snapshot before Siemens shut it down and removed access to the Git repository... OpenCourant continues with the OpenRadioss GNI AGPLv3 licensing and will be run as part of the Rocky Enterprise Software Foundation. They have run into a small issue though with part of OpenRadioss consisting of binary dependencies and not having the very latest versions prior to Siemens' removal of the repository. Details on that via this discussion thread for anyone that happens to have recent OpenRadioss binaries.
In other open source news, Kagi is ending their development work on the Orion Browser for Linux and Windows, reports the site Linuxiac — but Kagi "plans to open-source both versions so other developers or organizations can keep them going."

"Free your BIOS today!" urges the web page for GNU Boot, calling it "a 100% free software project aimed at replacing the nonfree boot software (like BIOS or UEFI) of computers with free boot software. GNU Boot is only a distribution: it reuses existing software projects like Coreboot, GRUB, SeaBIOS, etc. So it's not very different from 100% free GNU/Linux distributions like Trisquel or Guix.
Last month the Free Software Foundation announced they'd fiscally sponsor the project: "The BIOS is a delicate but essential part of software freedom for computing today," said Zoë Kooyman, executive director of the FSF. "GNU Boot aims to make sure that we can continue using our computers in freedom. With the way it builds on the work of others to replace UEFI, we know it can remain firm in the free software philosophy and stay vital to digital autonomy and user freedom." Free boot firmware, such as GNU Boot, is responsible for loading the computer's operating system.

The work done by GNU Boot contributors has similarities to work done by GNU/Linux distributions: they package software like Coreboot or GNU GRUB, contribute to the upstream repositories of these projects, and assist them with documentation, among other tasks... When asked about their project joining the FSF's fiscal sponsorship program, co-maintainer Adrien Bourmault stated: "Making this decision with the FSF allows us to focus more on what we do best: writing and debugging code that keeps our machines fully free." Projects whose scope and purpose align with the FSF's mission and further mission-related activities can become fiscally sponsored by joining the FSF's Working Together for Free Software Fund.

Long-time Slashdot reader Andreas(R) announces Northstar, a "minimalist" web browser written entirely from scratch in C — now available in version 1.0.11: One window, one page, one process — about 160,000 lines of original C, small enough for one person to read and audit end-to-end. It carries no upstream browser engine: no Gecko, no WebKit, no Blink. It is free software under the GNU General Public License, version 3 or later, and it runs on Linux, macOS and Windows...

Compliance is not inherited from an upstream engine; it is measured, section by section, against the specification text... Private by construction. No telemetry, no update pings, and no AI assistant or AI-style web APIs. Safe browsing checks a top-level navigation's host against a local SHA-256 blocklist before it is fetched — the check never leaves your machine. Cookies, storage and the cache are partitioned by origin.
It's logo reminds me of the old Netscape logo. (And I love the "Best viewed in..." GIF at the upper-right of its web site.)

Cloudflare has launched two open-weight decision models, Clef and Clef-flash, designed for structured yes/no, multiple-choice, and ranking tasks while also supporting images, video, and up to a 64K context window. Cloudflare says its models outperform TypeSafe's Jev on several benchmarks and can run locally from Hugging Face. The Register reports: For starters, Clef has an LLM backbone. According to Cloudflare, Clef uses specially post-trained, frozen versions of Qwen3.8-27B and Qwen3.5-9B for Clef and Clef-flash, respectively, with the Qwen backbone performing a prefill-only pass during inference. Clef is still fast - faster than Jev, to be fair - and scores choices in parallel after that prefill-only pass. It's not clear what Jev's underlying architecture is, as TypeSafe has kept that a secret.

As for its speed and capability, Clef moves fast. Cloudflare ran it against Jev and some other open decision models using the Jev Decision Index available on Hugging Face, and the company's own ranking suggests Clef is slightly slower than other open models, but more accurate, with Clef-flash just as accurate as most of the others, but far faster.

To be fair to the competition, Cloudflare self-reported its own scores against the benchmark, and they have yet to be reproduced for ranking on the official Decision Index. Cloudflare also ran Clef against TypeSafe's own benchmarks, and claimed it beat Jev in three out of four areas, only losing out on agent trace observability. Even if it were a bit slower or less accurate, Clef has another major leg up on Jev: It's not limited to classifying text -- it can also handle images and video. Additionally, Clef supports a 64k context window. Jev can also handle up to 64k tokens across a request, although its state plus longest individual question is limited to 32k.

"F-Droid, a third-party app repository that only distributes free and open-source software packages for Google's Android mobile platform, on Thursday announced version 2.0 of its Android app," reports The Register.

Though they also note "a big banner across the top of the F-Droid site" pointing to a site describing pending changes from Google that threaten the future of F-Droid... [D]evelopers who want their apps broadly distributed outside the official Google Play Store will need to register with Google and verify their identities. Google's Full Distribution option includes paying a one-time $25 fee, handing over a copy of a government-issued ID to verify one's identity, and conforming to Google's terms of service. Google also offers a free Limited Distribution option that doesn't require government ID verification but restricts distribution to 20 authorized devices, while apps from unverified developers can still be installed by users who enable Android's advanced installation flow.

The potential death warrant hanging over its head hasn't stopped the F-Droid team from rolling out a bunch of new features for an app it says it intends to keep working on for years to come... The team also credited the EU's many Digital Markets Act decisions against Google for making the installation experience smoother for users. F-Droid can now use a unified installation service for its apps thanks to the availability of a pre-approval API that allows users to approve an installation when they request it, rather than waiting until the app has finished downloading. That, said the F-Droid team, "brings the F-Droid install experience on official Android devices much closer to what the built-in app store can provide." Additionally, F-Droid 2.0 can fetch and install app updates automatically, which it now does by default.

All of those changes, however, won't matter much if Google pushes ahead undeterred with its plans to force registration onto non-Play Store developers. F-Droid's announcement on Thursday makes it seem that the team isn't going to go quietly.
F-Droid has gone 10 years without a major update, notes Ars Technica — and spent over a year developing F-Droid 2.0: The new F-Droid client was redesigned from scratch in Kotlin Compose, which is the standard for modern Android apps. This makes the store much more responsive, and there's optional support for Android's Material theming. The interface has also been cleaned up considerably, making the most important functions easier to access and hiding some others in overflow menus... Unlike the Play Store, F-Droid doesn't track your taps and installs to push ads and suggestions — it helps you find things and gets out of the way.

F-Droid now includes a huge number of categories, drilling down to specialized niches like firewalls, password managers, and VPNs. You can see all these groups in the search tab. There are also higher-level categories listed on the main Discover page. When searching for apps, F-Droid will now be able to return results based on app descriptions rather than just names.
"One of the goals of the rewrite was to lower the barrier for new contributors," F-Droid said in their announcement. "We are excited to begin rolling out F-Droid 2.0 to users over the coming weeks after 14 test releases." (And if you want the 2.0 release right now, it's available on the versions page.)

"In April this year, we saw Andy Nguyen turning the PS5 into a Linux-powered gaming PC," writes the blog It's FOSS.

It ran Steam games and emulators using the PS5's on-board hardware. But this week Andy announced he's "stopping all my work on PS5 Linux" and "stepping away from the PS5 scene." stopping work on porting the project to the PS5 Pro, which would've shipped sometime in 2027. Andy Nguyen: After pouring my heart and months of my life into it, including plans to finish PS5 Pro support and release in 2027, it's all down the sink.

The scene used to be a group of highly talented researchers, but now it is just a bunch of noobs using LLMs and writing hacks they don't even understand. Slop kiddies found the only hypervisor bug left, which I had also found a while ago, and decided to report to Sony. I asked them to at least wait for GTA 6 to come out so that people would have the opportunity to legally purchase the game and also enjoy Linux. They agreed to wait, but not a day passed and they decided to waste it instead.
Or, as It's FOSS tells it: Running Linux on a PlayStation console is possible because the PS5 Linux project was able to find a way past the hypervisor using exploits Sony had already patched, covering firmware 3.00 through 7.61. ..

[The bug's discoverer writes it was] found with what he calls his "trusty ai clanker machine" and no help from anyone else. He had even agreed to Andy's request to not disclose the findings. Unexpectedly, a third person, still unnamed, found the same bug using AI a few hours later. Anticipating that there would be more people finding the same bug, [he] decided to post the flaw on HackerOne.

The project's GitHub page and all the related repositories are still there. Nothing has been archived as of today, and if you wanted to, you could start contributing to the PS5 Linux project by taking over any pending work or cooking up new improvements... The PS5 Pro support Andy was building never reached the repository, so you would have to start from scratch... While Andy's departure is a blow to the plan for supporting newer PS5 firmware and the PS5 Pro, other contributors have shown that they can deliver work on the loader without him, and I am hopeful more will follow.

Targeting students and beginners, Adafruit released "CircuitPython" in 2017 (as a derivative of the MicroPython microcontroller-optimized programming language).

Now Adafruit managing director Phillip Torrone (also long-time Slashdot reader ptorrone) brings this update: Adafruit has published CircuitPython Turbo, a workflow that compiles selected Python functions into native machine code on a computer, then loads them onto compatible microcontroller boards.

It builds on MicroPython's Native and Viper emitters. In a documented Metro RP2040 fixed-point Mandelbrot test, Viper cut computation time from 8.335 seconds to 0.423 seconds, a 19.71x speedup over bytecode. The rest of the application stays in Python. The guide includes benchmarks, source code and hardware demos. The speedup is for the measured computation, not the whole application.
"Turbo support is now included in the latest official CircuitPython builds for RP2040 and RP2350 boards..." explains Torrone's announcement at Adafruit.com. "The new Turbo in CircuitPython helps when the board spends time calculating: making neopixel effects, drawing fractals, processing audio, filtering sensor readings, or preparing lots of pixels. Those projects can get smoother animation, quicker responses, or room to do more things at once." With Turbo, it's easier, better, and now even faster to make LED light up costumes that also reacts to sound at the same time, a sensor dashboard with animated graphics, or a tiny game doing physics while drawing the screen. Turbo speeds up the busy Python parts. It won't make a slow sensor or display connection faster... Your computer turns selected functions into instructions the chip can run directly. Python still handles the rest.

We have measured speedups, real display captures, and examples you can pull apart to see what happened. None of this arrived alone. CircuitPython, MicroPython, PyMCU, compiler tools, open hardware, and people sharing their work gave us pieces to connect. The Bao experiments take that idea somewhere else, handing calculations to four helper cores. Now we get to make those paths easier to use, compare results, and find the next useful thing. Maybe that's smoother animation, a responsive instrument, or an idea we haven't tried yet.

That's what I like about open source. Someone shares a piece, someone else sees a possibility, and we get to keep building it together.

"Ubuntu has managed to do away with GNU Core Utilities in its default stack," reports the blog It's FOSS.

The last three utilities — cp, mv and rm — have been moved to versions from the uutils project (which reimplements utilities in Rust). Everything else, from ls and cat to chmod and du, made that jump in earlier releases... Canonical started "oxidizing" Ubuntu last year, and Ubuntu 25.10 became the first release to ship [ the uutils project's] coreutils as the default. That release also made sudo-rs the default privilege tool, replacing a command that had been in place for decades.

26.04 was the release where the plan did slow down quite a bit, as Canonical kept cp, mv, and rm on their GNU versions due to a bunch of TOCTOU issues that were blocking the full implementation. These were caught during an audit, when Canonical commissioned Zellic for two rounds between December 2025 and March 2026, focusing on the most security-sensitive utilities first. Across both rounds, Zellic raised 113 issues, and 44 of them were assigned CVEs. Canonical says the vast majority have been resolved.

Getting here has had its ups and downs, and the last stretch was not clean. In July, uutils cp went back into the archive and came straight out again after it broke live image builds. The fix was quick; as the developers marked it "Critical," the fix went upstream, and the migration landed in time for 26.10.

When typing commands, nothing changes for you on the surface. uutils coreutils is designed to be a drop-in replacement for essential GNU tools, and the project treats any divergence from GNU as a bug, further pointing out that some options may still be missing or behave differently. So if you prefer staying on the GNU version, you have the option to install the coreutils-from-gnu package that houses all the required components.

Reservations are now live for Valve's "Steam Frame" VR headset (with its Linux-based SteamOS and an ARM CPU). "It starts at $1,059 for 256GB or $1,299 for 1TB," reports CNET, "and every purchase includes a copy of Half-Life: Alyx if you don't already own it." Reservations are open through Sept. 17 at 10 a.m. PT, "with customers randomly assigned a place in line after the reservation window closes."

CNET's editor at large even argues that the Steam Frame "isn't necessarily the future of XR, as much as it's a framework for evolving beyond the present." Their review calls it an "ambitious" VR headset that "feels like an experiment in progress." The ability to run other apps in windows can make Frame feel, at times, almost like a computer. Linux apps in desktop mode range from Chromium to Firefox to a bunch of other tools. I watched YouTube in one window while playing Portal 2 in other, and started to marvel at how flexible Frame could be. But VR games require a full immersive takeover of the headset... The Steam Frame can convert games intended for both PC VR and even Android APK files, using a conversion tool called Lepton... I haven't sideloaded anything yet, but Steam Frame in theory could be a Rosetta Stone for VR gaming, even tapping into some Android XR titles, but not out of the box...

2D games can be projected onto a near-range or farther-off theater mode screen that can be dragged around, resized and turned into a curved or flat monitor, much like with the Apple Vision Pro, Samsung Galaxy XR or Meta Quest. You can download any game in your Steam library to test, even if it's not technically listed as "Great on Frame" yet...

But the name "Frame" suggests a framework, something Valve's team acknowledged when I spoke to them during my review process... "We want this to be your PC, and people mod it, take it apart, make accessories for it," says Jeremy Selan, a software developer on the Steam Frame team. "We'll be putting out the CAD for all these [Steam Frame] systems. This is entirely based on open-source technology stacks based upon SteamOS. Our hope is that this isn't just one device, that this would be sort of the root of a growing SteamOS ecosystem. It already encompasses gaming and Proton and SteamOS and those Linux gaming capabilities. This is going to lay the foundation for a new sort of evolutionary tree of that, to also bring it into the VR and XR space."

NASA and IBM have released an open-source AI model trained on a large collection of lunar observations to help scientists analyze the Moon at scale. "The NASA-IBM Lunar Foundation Model gives scientists a foundation to explore the Moon at scale, connecting observations across instruments, revealing patterns that are difficult to see in isolation, and providing an open platform the global research community can build on," said IBM director of research for Europe, Juan Bernabe-Moreno. The Register reports: It is claimed as the first AI model to integrate observations captured in a range of modalities (data formats), and at different viewing angles and spatial scales. Instead of sifting through maps and images by hand or using low resolution machine learning models, scientists can use this to analyze geographic features, the pair say. In particular, NASA and IBM hope researchers will be able to discover previously unidentified lunar ice deposits, analyze volcanic features called Irregular Mare Patches, and identify and classify craters.

Lunar ice indicates the presence of water and oxygen, which may be useful for future manned missions. It is found in permanently shadowed regions, which are among the most difficult areas to observe. The NASA-IBM model combines multimodal and multi-resolution observations to better predict where ice may be present on the lunar surface. Alongside the model, IBM and NASA scientists compiled an open-source lunar dataset from over 30 spatially-aligned layers, using data from nine instruments across four missions. It combines tens of thousands of images and maps showing various geophysical properties of the lunar surface.

Switzerland has a population of 9,154,242. And its federal government just launched a pilot program to test open source alternatives to Microsoft 365 on 3,000 workstations, reports the blog It's FOSS. "That's about 7% of the federal workforce." The target is to complete the migration by end of 2027... On September 3, 2026, the Federal Council published results of "PoC BOSS", a feasibility proof-of-concept involving 172 federal employees who tested the openDesk suite, a German open-source collaboration platform. During the proof-of-concept phase, core office tasks like document processing and email received positive assessments, while large-scale video conferencing still showed technical limitations. Based on the 'success' of the PoC phase with 172 employees, the pilot is now launched for 3,000 employees...

According to Matthias Stürmer, professor at the Bern University of Applied Sciences, Microsoft's supremacy in public institutions poses three problems that are driving this migration. First is the risk of foreign access. US cloud legislation could expose Swiss government data to foreign authorities. Second is the risk to service continuity, as dependency on a single foreign vendor creates operational risk. The third risk is the escalating costs as proprietary licensing fees are rising with no Swiss leverage.

Switzerland's military cybersecurity unit, Cyber Command, is not waiting for the civilian pilot. It is already poised to replace Microsoft 365 entirely with openDesk by October 2026. It is pretty much the same reason. Military doesn't want foreign governments accessing sensitive Swiss data.
The article notes that during the pilot phase, the new system runs in parallel with Microsoft 365 rather than replacing it. But the article's author speculates that "If the pilot is successful, we might expect the migration to continue on all the 54,000 workstations owned by the federal administrations."

BrianFagioli writes: Audacity 4.0 has been released with a rebuilt Qt interface, a new clip-editing model, customizable workspaces, native high-DPI rendering, and a new AUP4 project format. The open source audio editor also adds ASIO playback and recording support to official Windows builds, while bringing major changes to recording, playback, plugins, and project handling. The overhaul comes with some tradeoffs. Audacity 4.0 currently lacks several features found in Audacity 3, including Time Tracks, Note and MIDI tracks, Mixer, Macro Manager and scripting pipe, VAMP and LADSPA plugin hosting, and play-at-speed. The developers say they plan to bring the missing functionality back in future releases.

BrianFagioli writes: Perplexity has built a local artificial intelligence engine designed specifically for Apple silicon and the Qwen3.6-35B-A3B model. Called Lily, the engine uses a Rust runtime and custom Metal kernels, with neither PyTorch nor MLX in its execution path. Perplexity says Lily averaged 23 percent faster prompt processing and 35 percent faster token generation than MLX-LM on an M5 Max MacBook Pro with 128GB of unified memory. Lily is more specialized than MLX-LM, which supports a much wider range of models and architectures. Perplexity says it plans to release Lily as open source, but the code is not available yet, leaving its performance claims dependent on internal testing for now.

Broadcom is launching "TrueSource," an effort to curate and secure open-source components used with its Tanzu platform, including Spring, RabbitMQ, and libraries across Java, Python, and Node.js. "The idea is to provide a set of solutions focused on providing clean and secure artefacts," Purnima Padmanabhan, vice president of Broadcom's Tanzu Division, told The Register. "We choose and build every Spring library, databases, other Java components," she said. The Register reports: Padmanabhan said that promise means VMware will also provide "TrueSource trusted artifacts" for code that is not part of Spring, including the wider Java ecosystem, Python, and Node.js. "Broadcom's curation process ensures that the libraries conform to a reference architecture and are supportable by the maintainers of record," according to a company statement. "Thousands of engineers across Broadcom's software divisions scan, fix, contribute to, and consume them every day."

A VMware spokesperson told The Register the Broadcom business unit "will work with and support maintainers on open source software and we will provide fixes to open source upstream for any active projects." "With Spring and RabbitMQ, we are the maintainers. For other open source software, we will work with the maintainers. We believe that the community maintainers must remain the source of truth," the spokesperson said.

This is just the sort of contribution that the open-source community wants vendors to do to reflect the value they extract from software they did not create alone. It's also the sort of thing vendors sometimes conclude they need to do to keep products based on FOSS viable.
