Asahi lead developer Hector Martin, writing in an email: I no longer have any faith left in the kernel development process or community management approach.

Apple/ARM platform development will continue downstream. If I feel like sending some patches upstream in the future myself for whatever subtree I may, or I may not. Anyone who feels like fighting the upstreaming fight themselves is welcome to do so.
The Register points out that the action follows this interaction with Linux Torvalds.

Hector Martin: If shaming on social media does not work, then tell me what does, because I'm out of ideas.

Linus Torvalds: How about you accept the fact that maybe the problem is you. You think you know better. But the current process works. It has problems, but problems are a fact of life. There is no perfect. However, I will say that the social media brigading just makes me not want to have anything at all to do with your approach. Because if we have issues in the kernel development model, then social media sure as hell isn't the solution.

A heated dispute has erupted in the Linux kernel community over the integration of Rust code, with kernel maintainer Christoph Hellwig likening multiple programming languages to "cancer" for the project's maintainability. The conflict centers on a proposed patch enabling Rust-written device drivers to access the kernel's DMA API, which Hellwig strongly opposed. While the dispute isn't about Rust itself, Hellwig argues that maintaining cross-language codebases severely compromises Linux's integrated nature. From a report: "Don't force me to deal with your shiny language of the day," he [Hellwig] wrote. "Maintaining multi-language projects is a pain I have no interest in dealing with. If you want to use something that's not C, be that assembly or Rust, you write to C interfaces and deal with the impedance mismatch yourself as far as I'm concerned." This resistance follows the September departure of Microsoft engineer Wedson Almeida Filho from the Rust for Linux project, citing "nontechnical nonsense."

Software developer and prolific blogger Herman Ounapuu, writing in a blog post: I liked Ubuntu. For a very long time, it was the sensible default option. Around 2016, I used the Ubuntu GNOME flavor, and after they ditched the Unity desktop environment, GNOME became the default option.

I was really happy with it, both for work and personal computing needs. Estonian ID card software was also officially supported on Ubuntu, which made Ubuntu a good choice for family members.

But then something changed. Ounapuu recounts how Ubuntu's bi-annual long-term support releases consistently broke functionality, from minor interface glitches to catastrophic system failures that left computers unresponsive. His breaking point came after multiple problematic upgrades affecting family members' computers, including one that rendered a laptop completely unusable during an upgrade from Ubuntu 20.04 to 22.04. Another incident left a relative's system with broken Firefox shortcuts and duplicate status bar icons after updating Lubuntu 18.04.

Canonical's aggressive push of Snap packages has drawn particular criticism. The forced migration of system components from traditional Debian packages to Snaps resulted in compatibility issues, broken desktop shortcuts, and government ID card authentication failures. In one instance, he writes, a Snap-related bug in the GNOME desktop environment severely disrupted workplace productivity, requiring multiple system restarts to resolve. The author has since switched to Fedora, praising its implementation of Flatpak as a superior alternative to Snaps.

In his post about the future of Fedora Workstation, Christian F.K. Schaller discusses how the Red Hat team plans to integrate AI with IBM's open-source Granite engine to enhance developer tools, such as IDEs, and create an AI-powered Code Assistant. He says the team is also working on streamlining AI acceleration in Toolbx and ensuring Fedora users have access to tools like RamaLama. From the post: One big item on our list for the year is looking at ways Fedora Workstation can make use of artificial intelligence. Thanks to IBMs Granite effort we know have an AI engine that is available under proper open source licensing terms and which can be extended for many different usecases. Also the IBM Granite team has an aggressive plan for releasing updated versions of Granite, incorporating new features of special interest to developers, like making Granite a great engine to power IDEs and similar tools. We been brainstorming various ideas in the team for how we can make use of AI to provide improved or new features to users of GNOME and Fedora Workstation. This includes making sure Fedora Workstation users have access to great tools like RamaLama, that we make sure setting up accelerated AI inside Toolbx is simple, that we offer a good Code Assistant based on Granite and that we come up with other cool integration points. "I'm still not sure how I feel about this approach," writes designer/developer and blogger, Bradley Taunt. "While IBM Granite is an open source model, I still don't enjoy so much artificial 'intelligence' creeping into core OS development. This also isn't something optional on the end-users side, like a desktop feature or package. This sounds like it's going to be built directly into the core system."

"Red Hat has been pushing hard towards AI and my main concern is having this influence other operating system dev teams. Luckily things seems AI-free in BSD land. For now, at least."

An anonymous reader quotes a report from Ars Technica: In what is becoming a sadly regular occurrence, two popular free software projects, X.org/Freedesktop.org and Alpine Linux, need to rally some of their millions of users so that they can continue operating. Both services have largely depended on free server resources provided by Equinix (formerly Packet.net) and its Metal division for the past few years. Equinix announced recently that it was sunsetting its bare-metal sales and services, or renting out physically distinct single computers rather than virtualized and shared hardware. As reported by the Phoronix blog, both free software organizations have until the end of April to find and fund new hosting, with some fairly demanding bandwidth and development needs.

An issue ticket on Freedesktop.org's GitLab repository provides the story and the nitty-gritty needs of that project. Both the X.org foundation (home of the 40-year-old window system) and Freedesktop.org (a shared base of specifications and technology for free software desktops, including Wayland and many more) used Equinix's donated space. [...] Alpine Linux, a small, security-minded distribution used in many containers and embedded devices, also needs a new home quickly. As detailed in its blog, Alpine Linux uses about 800TB of bandwidth each month and also needs continuous integration runners (or separate job agents), as well as a development box. Alpine states it is seeking co-location space and bare-metal servers near the Netherlands, though it will consider virtual machines if bare metal is not feasible.

Tom's Hardware reports: Facebook's heavy-handed censorship of Linux groups and topics was "in error," the social media juggernaut has admitted. Responding to reports earlier this week, sparked by the curious censorship of the eminently wholesome DistroWatch, Facebook contacted PCMag to say that it had made a mistake and that the underlying issue had been rectified.

"This enforcement was in error and has since been addressed. Discussions of Linux are allowed on our services," said a Meta rep to PCMag. That is the full extent of the statement reproduced by the source... Copenhagen-hosted DistroWatch says it has appealed against the Community Standards-triggered ban shortly after it noticed it was in effect (January 19). PCMag received the Facebook admission of error on January 28. The latest statement from DistroWatch, which now prefers posting on Mastodon, indicates that Facebook has lifted the DistroWatch links ban.
More details from PCMag: Meta didn't say what caused the crackdown in the first place. But the company has been revamping some of its content moderation and plans to replace its fact-checking methodology with a user-driven Community Notes, similar to X. "We're also going to change how we enforce our policies to reduce the kind of mistakes that account for the vast majority of the censorship on our platforms," the company said earlier this month, in another irony.

"Up until now, we have been using automated systems to scan for all policy violations, but this has resulted in too many mistakes and too much content being censored that shouldn't have been," Meta added in the same post.

Google is enhancing Android 16's Linux Terminal app to support graphical Linux applications, so Android Authority decided to put it to the test by running Doom. From the report: The Terminal app first appeared in the Android 15 QPR2 beta as a developer option, and it still remains locked behind developer settings. Since its initial public release, Google pushed a few changes that fixed issues with the installation process and added a settings menu to resize the disk, forward ports, and backup the installation. However, the biggest changes the company has been working on, which include adding hardware acceleration support and a full graphical environment, have not been pushed to any public releases.

Thankfully, since Google is working on this feature in the open, it's possible to simply compile a build of AOSP with these changes added in. This gives us the opportunity to trial upcoming features of the Android Linux Terminal app before a public release. To demonstrate, we fired up the Linux Terminal on a Pixel 9 Pro, tapped a new button on the top right to enter the Display activity, and then ran the 'weston' command to open up a graphical environment. (Weston is a reference implementation of a Wayland compositor, a modern display server protocol.)

We also went ahead and enabled hardware acceleration beforehand as well as installed Chocolate Doom, a source port of Doom, to see if it would run. Doom did run, as you can see below. It ran well, which is no surprise considering Doom can run on literal potatoes. There wasn't any audio because an audio server isn't available yet, but audio support is something that Google is still working on.

Facebook has banned posts mentioning Linux-related topics, with the popular Linux news and discussion site, DistroWatch, at the center of the controversy. Tom's Hardware reports: A post on the site claims, "Facebook's internal policy makers decided that Linux is malware and labeled groups associated with Linux as being 'cybersecurity threats.' We tried to post some blurb about distrowatch.com on Facebook and can confirm that it was barred with a message citing Community Standards. DistroWatch says that the Facebook ban took effect on January 19. Readers have reported difficulty posting links to the site on this social media platform. Moreover, some have told DistroWatch that their Facebook accounts have been locked or limited after sharing posts mentioning Linux topics.

If you're wondering if there might be something specific to DistroWatch.com, something on the site that the owners/operators perhaps don't even know about, for example, then it seems pretty safe to rule out such a possibility. Reports show that "multiple groups associated with Linux and Linux discussions have either been shut down or had many of their posts removed." However, we tested a few other Facebook posts with mentions of Linux, and they didn't get blocked immediately. Copenhagen-hosted DistroWatch says it has tried to appeal against the Community Standards-triggered ban. However, they say that a Facebook representative said that Linux topics would remain on the cybersecurity filter. The DistroWatch writer subsequently got their Facebook account locked... DistroWatch points out the irony at play here: "Facebook runs much of its infrastructure on Linux and often posts job ads looking for Linux developers."

UPDATE: Facebook has admited they made a mistake and stopped blocking the posts.

Amid the ongoing Linux 6.14 kernel development cycle, Phoronix spotted a pull request for ACPI updates which "will allow for faster suspend and resume cycles on some systems."

Wikipedia defines ACPI as "an open standard that operating systems can use to discover and configure computer hardware components" for things like power management and putting unused hardware components to sleep. Phoronix reports: The ACPI change worth highlighting for Linux 6.14 is switching from msleep() to usleep_range() within the acpi_os_sleep() call in the kernel. This reduces spurious sleep time due to timer inaccuracy. Linux ACPI/PM maintainer Rafael Wysocki of Intel who authored this change noted that it could "spectacularly" reduce the duration of system suspend and resume transitions on some systems...

Rafael explained in the patch making the sleep change:

"The extra delay added by msleep() to the sleep time value passed to it can be significant, roughly between 1.5 ns on systems with HZ = 1000 and as much as 15 ms on systems with HZ = 100, which is hardly acceptable, at least for small sleep time values."
One 2022 bug report complained a Dell XPS 13 using Thunderbolt took "a full 8 seconds to suspend and a full 8 seconds to resume even though no physical devices are connected." In November an Intel engineer posted on the kernel mailing list that the fix gave a Dell XPS 13 a 42% improvement in kernel resume time (from 1943ms to 1127ms).

Two computer scientists at the University of Waterloo in Canada believe changing 30 lines of code in Linux "could cut energy use at some data centers by up to 30 percent," according to the site Data Centre Dynamics.

It's the code that processes packets of network traffic, and Linux "is the most widely used OS for data center servers," according to the article: The team tested their solution's effectiveness and submitted it to Linux for consideration, and the code was published this month as part of Linux's newest kernel, release version 6.13. "All these big companies — Amazon, Google, Meta — use Linux in some capacity, but they're very picky about how they decide to use it," said Martin Karsten [professor of Computer Science in the Waterloo's Math Faculty]. "If they choose to 'switch on' our method in their data centers, it could save gigawatt hours of energy worldwide. Almost every single service request that happens on the Internet could be positively affected by this."

The University of Waterloo is building a green computer server room as part of its new mathematics building, and Karsten believes sustainability research must be a priority for computer scientists. "We all have a part to play in building a greener future," he said. The Linux Foundation, which oversees the development of the Linux OS, is a founder member of the Green Software Foundation, an organization set up to look at ways of developing "green software" — code that reduces energy consumption.
Karsten "teamed up with Joe Damato, distinguished engineer at Fastly" to develop the 30 lines of code, according to an announcement from the university. "The Linux kernel code addition developed by Karsten and Damato was based on research published in ACM SIGMETRICS Performance Evaluation Review" (by Karsten and grad student Peter Cai).

Their paper "reviews the performance characteristics of network stack processing for communication-heavy server applications," devising an "indirect methodology" to "identify and quantify the direct and indirect costs of asynchronous hardware interrupt requests (IRQ) as a major source of overhead...

"Based on these findings, a small modification of a vanilla Linux system is devised that improves the efficiency and performance of traditional kernel-based networking significantly, resulting in up to 45% increased throughput..."

The Linux 6.14 kernel now maps out support for Microsoft's "Copilot" key "so that user-space software can determine the behavior for handling that key's action on the Linux desktop," writes Phoronix's Michael Larabel. From the report: A change made to the atkbd keyboard driver on Linux now maps the F23 key to support the default copilot shortcut action. The patch authored by Lenovo engineer Mark Pearson explains [...]. Now it's up to the Linux desktop environments for determining what to do if the new Copilot key is pressed. The patch was part of the input updates now merged for the Linux 6.14 kernel.

"Nothing horrible or unexpected happened last week," Linux Torvalds posted tonight on the Linux kernel mailing list, "so I've tagged and pushed out the final 6.13 release."

Phoronix says the release has "plenty of fine features": Linux 6.13 comes with the introduction of the AMD 3D V-Cache Optimizer driver for benefiting multi-CCD Ryzen X3D processors. The new AMD EPYC 9005 "Turin" server processors will now default to AMD P-State rather than ACPI CPUFreq for better power efficiency....

Linux 6.13 also brings more Rust programming language infrastructure and more.
Phoronix notes that Linux 6.13 also brings "the start of Intel Xe3 graphics bring-up, support for many older (pre-M1) Apple devices like numerous iPads and iPhones, NVMe 2.1 specification support, and AutoFDO and Propeller optimization support when compiling the Linux kernel with the LLVM Clang compiler."

And some lucky Linux kernel developers will also be getting a guitar pedal soldered by Linus Torvalds himself, thanks to a generous offer he announced a week ago: For _me_ a traditional holiday activity tends to be a LEGO build or two, since that's often part of the presents... But in addition to the LEGO builds, this year I also ended up doing a number of guitar pedal kit builds ("LEGO for grown-ups with a soldering iron"). Not because I play guitar, but because I enjoy the tinkering, and the guitar pedals actually do something and are the right kind of "not very complex, but not some 5-minute 555 LED blinking thing"...

[S]ince I don't actually have any _use_ for the resulting pedals (I've already foisted off a few only unsuspecting victims^Hfriends), I decided that I'm going to see if some hapless kernel developer would want one.... as an admittedly pretty weak excuse to keep buying and building kits...
"It may be worth noting that while I've had good success so far, I'm a software person with a soldering iron. You have been warned... [Y]ou should set your expectations along the lines of 'quality kit built by a SW person who doesn't know one end of a guitar from the other.'"

Parallels Desktop now supports running 64-bit x86 operating systems on Apple Silicon Macs through its proprietary emulation engine, enabling users to run traditional Windows and Linux distributions. However, performance is said to be "really slow." How-To Geek reports: The latest Parallels Desktop 20.2 update adds early support for x86 emulation on Apple Silicon, allowing traditional x86 PC operating systems to work on newer Mac computers. There were already apps like UTM that could do it (most of them are based on QEMU), but this feature uses Parallels' "proprietary emulation engine" paired with Apple's built-in hypervisor. [...] Parallels on Apple Silicon can now "run existing x86_64 Windows 10, Windows 11*, Windows Server 2019/2022, and some Linux distributives with UEFI BIOS via Parallels Emulator." You can also create new Windows 10 21H2 and Windows Server 2022 virtual machines if needed.

There are some big limitations. You can only run 64-bit x86 operating systems -- sorry, FreeDOS fans -- but those 64-bit operating systems can run 32-bit applications. There's also no support for USB devices, nested virtualization (so WSL2 won't work), or the Parallels hypervisor. Performance will also be "really slow," since x86 instructions have to be translated to ARM. The company said, "Windows boot time is about 2-7 minutes, depending on your hardware. Windows operating system responsiveness is also low."

Linux creator Linus Torvalds announced a playful giveaway for kernel contributors: he'll hand-build a guitar effects pedal for one lucky developer selected at random, using his holiday hobby skills with pedal kits. To qualify, developers must have a 2024 commit in Torvalds' kernel git tree and email him with the subject "I WANT A GUITAR PEDAL". He'll pick a winner at random, use his own money to buy a pedal kit from a company called Aion FX, and then 'build it with my own shaky little fingers, and send it to the victim by US postal services.'" The Register reports: The odd offer appeared in his weekly state-of-the-kernel post, which on Sunday US time informed the Linux world that release candidate (rc) seven for version 6.13 of the Linux kernel "is slightly bigger than normal, but considering the timing, it's pretty much where I would have expected, and nothing really stands out." Torvalds therefore expects version 6.13 to debut next week, meaning it will arrive after his preferred seven release candidates and without delays caused by the usual holiday-period slowdown. Torvalds then added a postscript in which he revealed that he often uses the holiday season to build LEGO, which he frequently receives for Christmas and his late December birthday.

He kept up that tradition last year, but "also ended up doing a number of guitar pedal kit builds" which he described as "LEGO for grown-ups with a soldering iron." [...] Torvalds doesn't play guitar, but did the builds "because I enjoy the tinkering, and the guitar pedals actually do something and are the right kind of "not very complex, but not some 5-minute 555 LED blinking thing.'" He enjoyed the experience and wants to build more pedals, so has decided to give one away to a random kernel developer -- both as an act of generosity and to "check to see if anybody actually ever reads these weekly rc announcements of mine." Torvalds rated his past pedal-building efforts a "good success so far" but warned entrants "I'm a software person with a soldering iron."

"I will test the result to the best of my abilities, and the end result may actually work ... but you should set your expectations along the lines of "quality kit built by a SW person who doesn't know one end of a guitar from the other.'"

"I know, I know: 'Year of the Linux desktop ... yadda, yadda'," writes Steven Vaughan-Nichols, a ZDNet senior contributing editor. "You've heard it all before. But now there's a Linux-powered PC that many people will want..."

He's talking about Nvidia's newly-announced Project Digits, describing it as "a desktop with AI supercomputer power that runs DGX OS, a customized Ubuntu Linux 22.04 distro." Powered by MediaTek and Nvidia's Grace Blackwell Superchip, Project DIGITS is a $3,000 personal AI that combines Nvidia's Blackwell GPU with a 20-core Grace CPU built on the Arm architecture... At CES, Nvidia CEO Jensen Huang confirmed plans to make this technology available to everyone, not just AI developers. "We're going to make this a mainstream product," Huang said. His statement suggests that Nvidia and MediaTek are positioning themselves to challenge established players — including Intel and AMD — in the desktop CPU market. This move to the desktop and perhaps even laptops has been coming for a while. As early as 2023, Nvidia was hinting that a consumer desktop chip would be in its future... [W]hy not use native Linux as the primary operating system on this new chip family?

Linux, after all, already runs on the Grace Blackwell Superchip. Windows doesn't. It's that simple. Nowadays, Linux runs well with Nvidia chips. Recent benchmarks show that open-source Linux graphic drivers work with Nvidia GPUs as well as its proprietary drivers. Even Linus Torvalds thinks Nvidia has gotten its open-source and Linux act together. In August 2023, Torvalds said, "Nvidia got much more involved in the kernel. Nvidia went from being on my list of companies who are not good to my list of companies who are doing really good work." Canonical, Ubuntu Linux's parent company, has long worked closely with Nvidia. Ubuntu already provides Blackwell drivers.
The article strays into speculation, when it adds "maybe you wouldn't pay three grand for a Project DIGITS PC. But what about a $1,000 Blackwell PC from Acer, Asus, or Lenovo? All three of these companies are already selling MediaTek-powered Chromebooks...."

"The first consumer products featuring this technology are expected to hit the market later this year. I'm looking forward to running Linux on it. Come on in! The operating system's fine."

Phoronix reports on Valve's "Steam Survey" results for December 2024, saying the new numbers "reflect a nice upward trend for the Linux gaming statistics and a high point in recent times." In November the Steam Survey reflected a 2.03% marketshare for Linux... Roughly inline with what we have been seeing for Linux right at around the 2% threshold. With the just-published December survey numbers, there is a 0.29% increase to 2.29%...! When looking at the Linux numbers, SteamOS Holo accounts for around 36% of all Linux gamers... SteamOS Holo being the operating system of the Steam Deck and beginning to appear on other devices as well... Driven in large part by the Steam Deck relying on a custom AMD SoC/APU and AMD being popular with Linux gamers/enthusiasts for their open-source driver support, AMD CPU use on Linux commands a 73.6% marketshare.
In fact, December "saw AMD reach another record-high share among participants of Valve's survey," according to TechSpot — "up 3.02% last month, taking its total to 38.7% as Intel fell slightly to 63.4%..." Elsewhere, Windows 11 is now comfortably the most popular OS in the survey. It pulled ahead another 2% to an almost 55% share in December as Windows 10 dropped to 42.3%... However, it's a different story when looking at global users: Windows 10's share has increased two months in a row to 62.7% while Windows 11 has declined to 34.1%. Rounding up the rest of the survey, 16GB of RAM remains the most popular amount of system RAM but it's lead is declining as second-place 32GB grows; a trend that is mirrored in the VRAM category...
Phoronix adds that the Windows percent "pulled back by 0.51% to 96.1% while Apple macOS also gained 0.22% going up to a 1.61% marketshare."

The long-anticipated "year of the Linux desktop" could see renewed interest in 2025 as Microsoft's planned end of support for Windows 10 approaches, potentially driving users to explore alternatives.

With Windows 10 reaching end of support in October 2025, many users will face decisions about upgrading hardware for Windows 11 or considering different operating systems entirely. Linux distributions have evolved to offer increasingly polished desktop experiences, with improving hardware compatibility and familiar user interfaces.

2024 saw Linux adoption grow thanks to the Steam Deck's success, reaching a 4.04% market share in December, up from 3.85% during the same time last year. More Linux laptops, improved gaming compatibility, and growing awareness of its benefits also contributed to its steady rise.

Berlin-based T2 Linux developer René Rebe is also long-time Slashdot reader ReneR — and popped by with a special announcement for the holidays: The T2 Linux team has unveiled T2 Linux SDE 24.12, codenamed "Sky's the Limit!", delivering a massive update for this highly portable source-based Linux distribution... With 3,280 package updates, 206 new features, and the ability to boot on systems with as little as 512MB RAM, this release further strengthens T2 Linux's position as the ultimate tool for developers working across diverse hardware and embedded systems.
Some highlights from Rene's announcement:

• "The release includes 37 pre-compiled ISOs with Glibc, Musl, and uClibc, supporting 25 CPU architectures like ARM(64), RISCV(64), Loongarch64, SPARC(64), and vintage retro computing platforms such as M68k, Alpha, and even initial Nintendo Wii U support added."

• " The Cosmic Desktop, a modern Rust-based environment, debuts alongside expanded application support for non-mainstream RISC architectures, now featuring LibreOffice, OpenJDK, and QEMU."

And T2sde.org gives this glimpse of the future:

"While initially created for the Linux kernel, T2 already has proof-of-concept support for building 'home-brew' pkg for Other OS, including: BSDs, macOS and Haiku. Work on alternative micro kernels, such as L4, Fuchsia, RedoxOS or integrating building 'AOSP' Android is being worked on as well."

BrianFagioli shares a report from BetaNews: As we close out 2024, we Linux enthusiasts are once again looking ahead to what the future holds. While Linux has long been the unsung hero of technology, powering servers, supercomputers, and the cloud, it's also a dominant force in the consumer space, even if many don't realize it. With Android leading the way as the most widely used Linux-based operating system, 2025 is shaping up to be another landmark year for the open source world Here are the predictions mentioned in the article:

- Linux will continue to dominate the enterprise sector
- Linux will further solidify its role in powering cloud infrastructure, with major providers like AWS and Google Cloud relying on it.
- Gaming on Linux is set to grow in 2025
- Linux will play a major role in AI development
- Linux's appeal to developers and tech enthusiasts will remain strong
- The open source movement will grow stronger

What additional predictions do you have for Linux in 2025?
