- [$] Removing read-only transparent huge pages for the page cache
Things do not always go the way kernel developers think they will. Whenthe kernel gained support for the creation of read-only transparent hugepages for the page cache in 2019, the developer of that feature, Song Liu,added aKconfig file entry promising that support for writable hugepages would arrive "in the next few release cycles". Over six yearslater, that promise is still present, but it will never be fulfilled.Instead, the read-only option will soon be removed, reflecting how the coreof the memory-subsystem has changed underneath this particular feature.

- [$] A flood of useful security reports
The idea of using large language models (LLMs) to discover security problems isnot new. Google's Project Zeroinvestigatedthe feasibility of using LLMs for security research in 2024. At the time, theyfound that models could identify real problems, but required a good deal ofstructure and hand-holding to do so on small benchmark problems. In February2026, Anthropicpublished a reportclaiming that the company's most recent LLM at that point in time, Claude Opus 4.6, had discoveredreal-world vulnerabilities in critical open-source software, including the Linuxkernel, with far less scaffolding. On April 7, Anthropic announced a new experimental model that issupposedly even better; which they havepartnered with the Linux Foundationto supply to some open-source developers with access to the tool for security reviews.LLMs seem to have progressed significantly in the last few months, a changewhich is being noticed in the open-source community.

It has been a little while since LWN last surveyed tools for managing a digitalmusic collection. In the intervening decades, many Linux users have moved on tomusic streaming services, found them wanting, and are looking to curate their owncollection once again. There are plenty of choices when it comes toripping, managing, and playing digital audio; so many, in fact, that it can be abit daunting. After years of tinkering, I've found a few tools that work well formanaging my digital library: the first I'd like to cover is the fre:ac free audio encoder for ripping music fromCDs and converting between audio formats.
- [$] An API for handling arithmetic overflow
On March 31, Kees Cook shareda patch set that represents the culmination of more than a year of worktoward eliminating the possibility of silent, unintentional integer overflow inthe kernel. Linus Torvalds wasnot pleased with the approach, leading to a detailed discussion about themeaning of "safe" integer operations and the design of APIs for handling integeroverflows. Eventually, the developers involved reached a consensus for adifferent API that should make handling overflow errors in the kernel much lessof a hassle.
- Nix privilege escalation security advisory
The NixOS project has announceda critical vulnerability in many versions of the Nix packagemanager's daemon. The flaw was introduced as part of a fix for aprior vulnerability in 2024. According to the advisory,all default configurations of NixOS and systems building untrusted derivationsare impacted.
A bug in the fix for CVE-2024-27297allowed for arbitrary overwrites of files writable by the Nix processorchestrating the builds (typically the Nix daemon running as root inmulti-user installations) by following symlinks during fixed-outputderivation output registration. This affects sandboxed Linux builds -sandboxed macOS builds are unaffected. The location of the temporaryoutput used for the output copy was located inside the build chroot. Asymlink, pointing to an arbitrary location in the filesystem, could becreated by the derivation builder at that path. During outputregistration, the Nix process (running in the host mount namespace)would follow that symlink and overwrite the destination with thederivation's output contents.
In multi-user installations, this allows all users able to submitbuilds to the Nix daemon (allowed-users - defaulting to all users) togain root privileges by modifying sensitive files.

In 2024 the Verge's consumer tech reporter paid $173 for a WD Black SN850X 2TB SSD. But "now that same SSD costs $649..." "Like with RAM, demand from the AI industry is swallowing up supply from a limited number of manufacturers, leading to a drastic reduction in the inventory that's available to consumers" — and skyrocketing prices:The price on my WD Black drive nearly quadrupled since November 2025, and consumer SSDs across the board are seeing similar increases, much like with RAM. The 4TB version of the popular Samsung 990 Pro SSD previously cost $320, but will now run you nearly $1,000. External SanDisk SSDs saw a 200 percent price hike at the Apple Store in March.... According to price trends from PC Part Picker, NVMe SSD prices began ticking upward in December 2025, with prices on 256GB to 4TB SSDs now double or triple what they were just a few months ago, and continuing to climb.

- Two-Week Social Media 'Detox' Erases a Decade of Age-Related Decline, Study Finds
Critics say social media is engineered to be as addictive as tobacco or gambling, writes the Washington Post — while adding that "the science has been moving in parallel with the court's recognition."A growing body of research links heavy social media use not only to declines in mental health but to measurable cognitive effects — on attention, memory and focus — that in some studies resemble accelerated aging. Science also suggests we have more control than we realize when it comes to reversing this damage, and the solution is surprisingly simple: Take a break... "Digital detoxes" can sound like a fad. But in one of the largest studies to date, published in PNAS Nexus and involving more than 467 participants with an average age of 32, even a short time away produced striking results — effectively erasing a decade of age-related cognitive decline. For 14 days, participants used a commercially available app, Freedom, to block internet access on their phones. They were still allowed calls and text messages, essentially turning a smartphone into a dumb phone. Their time online decreased from 314 minutes to 161 minutes, and by the end of the period the participants had improvements in sustained attention, mental health as well as self-reported well-being. The improvement in sustained attention was about the same magnitude as 10 years of age-related decline, the researchers noted, and the effect of the intervention on depression symptoms was larger than antidepressants and similar to that of cognitive behavioral therapy. But two things were even more mind-blowing... Even those people who cheated and broke the rules after a few days seemed to have positive effects from the break; and in follow-up reports after the two weeks, many people reported the positive effects lingered. "So you don't have to necessarily restrict yourself forever. Even taking a partial digital detox, even for a few days, seems to work," Kushlev said. The article also notes a November study at Harvard published in JAMA Network Open where nearly 400 people 'found that even a short break can make a measurable difference: After just one week of reduced smartphone use, participants reported drops in anxiety (16.1 percent), depression (24.8 percent) and insomnia (14.5 percent)..." "Other experiments point in the same direction — whether decreasing social media use by an hour a day for one week or stepping away from just Facebook and Instagram."

- Firefox vs. Chrome: Which Performs Better on a Linux Laptop?
Phoronix staged "a showdown" between Firefox and Chrome, testing them both on an Intel Panther Lake laptop running Ubuntu 26.04.JetStream 3.0 was announced at the end of March as the latest major web browser benchmark. This updated version of JetStream is focused on intensive portions of modern JavaScript and WebAssembly web applications... Google Chrome 147 came in at 1.47x the performance of Mozilla Firefox 149. A very strong showing for Google's web browser and to not much surprise Google engineers have been heavily involved in JetStream 3 as part of its open governance model. Chrome debuts very well on JetStream 3 while it will be interesting to see what optimizations Mozilla engineers pursue in the months ahead... In the recent Speedometer 3.1 benchmark update that is focused on browser responsiveness, Chrome was at 1.24x the performance of Firefox... Firefox picked up wins in the MotionMark and StyleBench browser benchmarks. Google Chrome meanwhile continued to dominate in the JavaScript heavy benchmarks... In some of the WebAssembly benchmarks, there was at least some healthy competition between Firefox and Chrome on Linux. Across the web browser benchmarks, the Core Ultra X7 358H power consumption came in at 11.44 Watts on average for Chrome and 11.74 Watts for Firefox. Quite close. The slight CPU power difference may come down to the CPU usage with Chrome coming in slightly lower at 8.13% on average to 8.35% with Firefox. Chrome also came in at slightly lower memory consumption across all the benchmarks with total memory usage on average at 4.67GB to Firefox at 4.83GB.

- The End of 'Star Trek'? Every Single Series Now Cancelled
"Every single Star Trek series has been canceled..." reports ScreenRant. "There is "no Star Trek in production or greenlit for the first time in nearly a decade." While there were five active Star Trek series just a few years ago, Star Trek: Strange New Worlds filmed its fifth and final season in the fall of 2025, and Star Trek: Starfleet Academy "wrapped filming its second and final season at the end of February." (Though ironically, both Star Trek series still have seasons yet to premiere, with two season of Strange New Worlds mean it may continue airing through 2027.)TrekCentral reports that the sets for Star Trek: Starfleet Academy are now being torn down... There will be a local online auction for parts of the set on Friday. Additionally, Star Trek: Strange New Worlds' sets are also being taken down... Star Trek: Starfleet Academy boasted the largest sets ever built for Star Trek. The demolition of Starfleet Academy's stunning sets includes the loss of the multi-level atrium, which had the Starfleet Wall of Heroes, the USS Athena's bridge, and the classrooms.

- US Demands Reddit Unmask ICE Critic, Summons Firm To Grand Jury
An anonymous reader quotes a report from Ars Technica: The Trump administration has stepped up an effort to unmask a Reddit user who criticized Immigration and Customs Enforcement (ICE). After failing to obtain information through a summons issued (PDF) to Reddit, the government reportedly issued a subpoena demanding that Reddit provide the information and appear before a grand jury in Washington, DC. The Intercept described the subpoena today. "According to a subpoena obtained by The Intercept, Reddit has until April 14 to provide a wide range of personal data on one of its users, whom US Immigration and Customs Enforcement agents have been trying unsuccessfully to identify for more than a month," the article said. The legal saga began in US District Court for the Northern District of California. On March 12, the anonymous Reddit user whose information is being sought filed a motion (PDF) to quash a summons seeking a host of information from Reddit. The summons was issued by the Department of Homeland Security and directed Reddit to turn information over to an ICE senior special agent. The summons cited authority under 19 U.S. Code 1509, which is part of the Smoot-Hawley Tariff Act of 1930. The motion to quash said the summons is not authorized by the law, which deals with imports of boats, alcoholic drinks, and animals, among other things. "J. Doe is a US citizen who has not traveled out of the country, is not engaged in any international commerce, has no business concerns outside the United States, and primarily uses their Reddit account to engage in political speech relevant to their local community," said the filing by the Civil Liberties Defense Center (CLDC), which represents the Reddit user. "Yet the government claims the right to obtain Doe's name, telephone number, home address, banking and credit card information, IP addresses, telephone model number(s), and the names of any other accounts associated with their Reddit account. The information sought by the government in no way pertains to customs or importing or exporting merchandise, and is clearly intended to chill free speech." "We should be very, very, very concerned that they've now taken one of these to a grand jury," said David Greene, senior counsel for the Electronic Frontier Foundation. "It's something to be taken very seriously." A Reddit spokesperson told Ars today that "we seek to inform users of any legal process compelling disclosure of their data, as we did in this case, because users should have the agency to protect their own information and are often better positioned to challenge requests that impact them." "We do not voluntarily share information with any government, especially not on users exercising their rights to criticize the government or plan a protest. We review every inquiry for legal sufficiency and routinely object to requests that are overbroad or threaten civil rights. When legally compelled to disclose data, we provide only the minimum required and notify the user whenever possible so they can defend their interests."

- CPUID Site Hijacked To Serve Malware Instead of HWMonitor Downloads
Attackers briefly hijacked part of CPUID's backend and swapped legitimate download links on its site with malware-laced ones. "The issue hit tools like HWMonitor and CPU-Z, with users on Reddit and elsewhere starting to notice something wasn't right when installers tripped antivirus alerts or showed up under odd names," reports The Register. From the report: CPUID has since confirmed the breach, pinning it on a compromised backend component rather than tampering with its software builds. "Investigations are still ongoing, but it appears that a secondary feature (basically a side API) was compromised for approximately six hours between April 9 and April 10, causing the main website to randomly display malicious links (our signed original files were not compromised)," one of the site's owners said in a post on X. "The breach was found and has since been fixed." The files themselves appear to have been left alone and remain properly signed, so it doesn't seem like anyone got into the build process. Instead, the problem sat in front of that, in how downloads were being served. For anyone who hit the site during that stretch, though, that distinction offers little comfort. If the link you clicked had been swapped out, you were pulling whatever it pointed to, whether you realized it or not.

- To Fill Air Traffic Controller Shortage, FAA Turns To Gamers
An anonymous reader quotes a report from the New York Times: As the Trump administration seeks to fill a national shortage of air traffic controllers, officials are targeting a new talent pool: gamers. The Federal Aviation Administration on Friday is making a recruiting push aimed at avid players of video games, as the agency strives to fill thousands of vacancies that lawmakers have said leave the traveling public less safe. In a new YouTube ad, the agency is using flashy graphics and the promise of six-figure salaries to convince video game enthusiasts to apply their trigger fingers in service of air safety. In recent years, video gamers have emerged as a target demographic for recruiters at a number of federal agencies, including the military and the Department of Homeland Security. They are welcomed for their hand-eye coordination, quick decision-making in complex environments and ability to remain focused on screens for hours on end. "To reach the next generation of air traffic controllers, we need to adapt," Transportation Secretary Sean Duffy said in a statement. Focusing recruiting efforts on gamers, he added, "taps into a growing demographic of young adults who have many of the hard skills it takes to be a successful controller." [...] The F.A.A. plans to begin prioritizing recruiting gamers over more traditional avenues like college fairs, officials said, pointing out that only 25 percent of controllers have a traditional college degree, while the vast majority appear to have logged hours gaming. During the presidential transition in 2024, incoming Trump administration officials polled about 250 new air traffic academy graduates over six weeks. Only two of those interviewed were not gamers, according to F.A.A. officials [...]. Students who failed out of the training academy were not similarly queried, officials said, though they have plans to conduct more comprehensive exit interviews in the future. Still, the overwhelming presence of gaming habits among graduates tracked with what they were hearing anecdotally from controllers already certified to work in towers and other air traffic facilities, the officials said, many of whom liked to play video games during breaks in their shifts.

- Artemis II Astronauts Splash Down Off California's Coast
NASA's Artemis II crew safely splashed down off the California coast after completing a 10-day trip around the moon and back. "This is not just an accomplishment for NASA," sad NASA Administrator Jared Isaacman. "This is an accomplishment for humanity, again, a historic mission to the moon and back." From a report: Isaacman is aboard the USS John. P Murtha Navy recovery vessel, where the astronauts will be brought once they've been retrieved from the Orion capsule, and he shared "there is a lot to celebrate right now on on a mission well accomplished for Artemis II." Isaacman also complimented the crew as "absolutely professional astronauts, wonderful communicators and almost poets" "" as well as "ambassadors from humanity to the stars." "I can't imagine a better crew than the Artemis II crew that just completed a perfect mission right now. We are back in the business of sending astronauts to the moon and bringing them back safely. This is just the beginning. We are going to get back into doing this with frequency, sending missions to the moon until we land on it in 2028 and start building our base." Isaacman also said it's time to start preparing for Artemis III, expected to launch in 2027. You can watch the moment of the splashdown here.

- Chimpanzees In Uganda Locked In Vicious 'Civil War', Say Researchers
Researchers say the world's largest known wild chimpanzee community in Uganda fractured into rival factions and has been locked in a vicious "civil war" for the last eight years. "It is not clear exactly why the once close-knit community of Ngogo chimpanzees at Uganda's Kibale National Park are at loggerheads, but since 2018 the scientists have recorded 24 killings, including 17 infants," reports the BBC. From the report: [O]ver several decades, [lead author Aaron Sandel] said the nearly 200 Ngogo chimpanzees had lived in harmony. There were divided into two sets - known to researchers as Western and Central - but they had existed overall as a cohesive group. Sandel said he first noticed them polarizing in June 2015, when the Western chimpanzees ran away and were chased by the Central group. "Chimpanzees are sort of melodramatic," he said, explaining that following arguments there would ordinarily be "screaming and chasing" and then later, they would grooming and co-operating. But following the 2015 dispute, the researchers saw that there was a six-week avoidance period between the two sets, with interactions becoming more infrequent. When they did occur, Sandel said they were "a little more intense, a little more aggressive." Following the emergence of the two distinct groups in 2018, members of the Western group started attacking the Central chimpanzees. In 24 targeted attacks since the split, at least seven adult males and 17 infants from the Central chimps have been killed, the study found, although the researchers believe the actual number of deaths are higher. The researchers believe many factors such as the group size and subsequent competition of resources, and "male-male competition" for reproducing may be to blame. But they say there were three likely catalysts:- The first, were the deaths of five adult males and one adult female -- for reasons unknown -- in 2014, which could have disrupted social networks and weakened social ties across the subgroups- The following year, there was a change in the alpha male, which the study says coincided with the first period of separation between the Western and Central groups. "Changes in the dominance hierarchy can increase aggression and avoidance in chimpanzees," it explained- The third factor was the deaths of 25 chimpanzees, including four adult males and 10 adult females, as a result of a respiratory epidemic, in 2017, a year before the final separation. One of the adult males who died was "among the last individuals to connect the groups," the research paper said. The study has been published in the journal Science.

- EU Parliament Fails To Renew Loophole Allowing Tech Firms To Report Abuse
Bruce66423 shares a report from the Guardian: The European parliament has blocked the extension of a law that permits big tech firms to scan for child sexual exploitation on their platforms, creating a legal gap that child safety experts say will lead to crimes going undetected. The law, which was a carve-out of the EU Privacy Act, was put in place in 2021 as a temporary measure allowing companies to use automated detection technologies to scan messages for harms, including child sexual abuse material (CSAM), grooming and sextortion. However, it expired on April 3, and the EU parliament decided not to vote to extend it, amid privacy concerns from some lawmakers. The regulatory gap has created uncertainty for big tech companies, because while scanning for harms on their platforms is now illegal, they still remain liable to remove any illegal content hosted on their platforms under a different law, the Digital Services Act. Google, Meta, Snap and Microsoft said they would continue to voluntarily scan their platforms for CSAM, in a joint statement posted on a Google blog. Bruce66423 adds: "Child abuse as the excuse for avoiding privacy protections. Who would have thought it?"

- The disturbing white paper Red Hat is trying to erase from the internet
It shouldnt be a surprise that companies and for our field, technology companies specifically working with the defense industry tends to raise eyebrows. With things like the genocide in Gaza, the threats of genocide and war crimes against Iran, the mass murder in Lebanon, its no surprise that western companies working with the militaries and defense companies involved in these atrocities are receiving some serious backlash. With that in mind, it seems Red Hat, owned by IBM, is desperately trying to scrub a certain white paper from the internet. Titled Compress the kill cycle with Red Hat Device Edge!, the 2024 white paper details how Red Hats products and technologies can make it easier and faster to, well, kill people. Links to the white paper throw up 404s now, but it can still easily be found on the Wayback Machine and other places. Its got some disturbingly euphemistic content. The find, fix, track, target, engage, assess (F2T2EA) process requires ubiquitous access to data at the strategic, operational and tactical levels. Red Hat Device Edge embeds captured, analyzed, and federated data sets in a manner that positions the warfighter to use artificial intelligence and machine learning (AI/ML) to increase the accuracy of airborne targeting and mission-guidance systems. Delivering near real-time data from sensor pods directly to airmen, accelerating the sensor-to-shooter cycle. Sharing near real-time sensor fusion data with joint and multinational forces to increase awareness, survivability, and lethality. The new software enabled the Stalker to deploy updated, AI-based automated target recognition capabilities. If the target is an adversary tracked vehicle on the far side of a ridge, a UAS carrying a server running Red Hat Device Edge could transmit video and metadata directly to shooters. ↫ Red Hat white paper titled Compress the kill cycle with Red Hat Device Edge! I dont think theres something inherently wrong with working together with your nations military or defense companies, but that all hinges on what, exactly, said military is doing and how those defense companies products are being used. The focus should be on national defense, aid during disasters, and responding to the legitimate requests of sovereign, democratic nations to come to their defense (e.g. helping Ukraine fight off the Russian invasion). Theres always going to be difficult grey areas, but any military or defense company supporting the genocide in Gaza or supplying weapons to kill women and children in Iran is unequivocally wrong, morally reprehensible, and downright illegal on both an international and national level. It clearly seems someone at Red Hat feels the same way, as the company has been trying really hard to memory-hole this particular white paper, and considering its word choices and the state of the world today, its easy to see why. Of course, the internet never forgets, and I certainly dont intend to let something like this slide. We all know companies like Microsoft, Oracle, and Google have no qualms about making a few bucks from a genocide or two, but it always feels a bit more traitorous to the cause when its an open source company doing the profiting. It feels like Red Hat is trying to have its cake and eat it too, by, as an IBM subsidiary, trying to both profit from the vast sums of money sloshing around in the US military industrial complex as well as maintain its image as a scrappy open source business success story shitting bunnies and rainbows. Its a long time ago now that Red Hat felt like a genuine part of the open source community. Most of us both outside and inside of Red Hat, Im sure have been well aware for a long time now that those days are well behind us, and I guess Red Hat doesnt like seeing its kill cycle this compressed.
- FreeBSD works best on one of these laptops
If you want to run FreeBSD on a laptop, youre often yanked back to the Linux world of 20 years ago, with many components and parts not working and other issues such as sleep and wake problems. FreeBSD has been hard at work improving the experience of using FreeBSD on laptops, and now this has resulted in a list of laptops which work effortlessly with the venerable operating system. Theres only about 10 laptops on the list so far, but they do span a range of affordability and age, with some of them surely being quite decent bargains on eBay or whatever other used stuff marketplace you use. If you want to use FreeBSD on a laptop, but dont want to face any surprises or do any difficult setup, get one of the laptops on this list a list which will surely expand over time.
- Fixing AMDGPUs VRAM management for low-end GPUs
It may sound unbelievable to some, but not everyone has a datacenter beast with 128GB of VRAM shoved in their desktop PCs. Around the world people tell the tale of a particularly fierce group of Linux gamers: Those who dare attempt to play games with only 8 gigabytes of VRAM, or even less. Truly, it takes exceedingly strong resilience and determination to face the stutters and slowdowns bound to occur when the system starts running low on free VRAM. Carnage erupts inside the kernel driver as every application fights for as much GPU memory as it can hold on to. Any game caught up in this battle for resources will surely not leave unscathed. That is, until now. Because I fixed it. ↫ Natalie Vock The solution is to use cgroups to control the kernels memory eviction policies, so that applications that should get priority when it comes to VRAM allocation like games dont get their memory evicted from VRAM to system RAM. Basically, evict everything else from VRAM before touching the protected application. This way, something like a game will have much more consistent access to more VRAM, thereby reducing needless memory evictions that harm performance. Its a clever solution that makes use of a ton of existing Linux tools, meaning its also much easier to upstream, implement, and support. Excellent work.
- Why do Macs ask you to press random keys when connecting a new keyboard?
You might have seen this, one of the strangest and most primitive experiences in macOS, where you’re asked to press keys next to left Shift and right Shift, whatever they might be. Perhaps I can explain. ↫ Marcin Wichary It seems pretty obvious to me thats what it was for, but I guess many normal, regular people have never seen anything but one particular keyboard configuration (ANSI for Americans, ISO for some Europeans, etc.) keyboards. Perhaps they dont realise that not only are there ANSI keyboards with other layouts, but also entirely different keyboard configurations (mainly ISO and JIS). Interestingly, my home country of The Netherlands uses a US English layout on an ANSI configuration, but of course, its the US International variant, either with deadkeys or using AltGr for the various accented/special characters we use. In my current country of residence, Sweden, they use this utterly wild and incomprehensible ISO layout where Shift unlocks characters on the bottom of keys, while AltGr unlocks characters at the top, the exact opposite of literally every other keyboard Ive ever used (US Intl, classic Dutch (no longer used), German, French, etc.). Its utterly bizarre, but entirely normal to my Swedish wife. We cannot use each others keyboards.
- USB for software developers
This post aims to be a high level introduction to using USB for people who may not have worked with Hardware too much yet and just want to use the technology. There are amazing resources out there such as USB in a NutShell that go into a lot of detail about how USB precisely works (check them out if you want more information), they are however not really approachable for somebody who has never worked with USB before and doesn’t have a certain background in Hardware. You don’t need to be an Embedded Systems Engineer to use USB the same way you don’t need to be a Network Specialist to use Sockets and the Internet. ↫ Nik WerWolv! A bit of a generic title, but the article details how to write a USB driver.

This past month, theres been considerable graphics improvements, better deadlock detection in the kernel, improved Unicode support thanks to switching over to ncurses library variant with Unicode support, and much more. Alongside these, youll find the usual long list of kernel, driver, and relibc changes, bugfixes, and improvements. This month also covered three topics weve already discussed individually: Redox new no- AI! code policy, capability-based security in Redox, and the brand-new CPU scheduler.
- Mac OS X 10.0 Cheetah ported to Nintendo Wii
Since its launch in 2007, the Wii has seen several operating systems ported to it: Linux, NetBSD, and most-recently, Windows NT. Today, Mac OS X joins that list. In this post, I’ll share how I ported the first version of Mac OS X, 10.0 Cheetah, to the Nintendo Wii. If you’re not an operating systems expert or low-level engineer, you’re in good company; this project was all about learning and navigating countless “unknown unknowns”. Join me as we explore the Wii’s hardware, bootloader development, kernel patching, and writing drivers and give the PowerPC versions of Mac OS X a new life on the Nintendo Wii. ↫ Bryan Keller And all of this, because someone on Reddit said it couldnt be done. It wont surprise you to learn that the work required was extensive, from writing a custom bootloader to digging through the XNU source code, applying binary patches to the kernel during the boot process, building a device tree, writing the necessary drivers, and so much more. Even just setting up a development environment was a pretty serious undertaking. Especially writing the drivers posed an interesting and unique challenge, as the Wii doesnt use PCI to connect and expose its hardware components. Instead, components are connected to a dedicated SoC with its own ARM processor that talks to the main Wii PowerPC processor, exposing hardware that way. This meant that Keller had to write a driver for this chip first, before moving on to the device drivers for devices connected to this ARM SoC graphics drivers, input drivers, and so on. After a ton more work and overcoming several complex roadblocks, we now have Mac OS X 10.0 Cheetah on the Nintendo Wii. Amazing.
- Plan 9 is a uniquely complete operating system
From 2024, but still accurate and interesting: Plan 9 is unique in this sense that everything the system needs is covered by the base install. This includes the compilers, graphical environment, window manager, text editors, ssh client, torrent client, web server, and the list goes on. Nearly everything a user can do with the system is available right from the get go. ↫ moody This is definitely something that sets Plan 9 apart from everything else, but as moody 9front developer notes, this also has a downside in that development isnt as fast, and Plan 9 variants of tools lack features upstream has for a long time. He further adds that he think this is why Plan 9 has remained mostly a hobbyist curiosity, but Im not entirely sure thats the main reason. The cold and harsh truth is that Plan 9 is really weird, and while that weirdness is a huge part of its appeal and I hope it never loses it, it also means learning Plan 9 is really hard. I firmly believe Plan 9 has the potential to attract more users, but to get there, its going to need an onboarding process thats more approachable than reading 9fronts frequently questioned answers, excellent though they are. After installing 9front and loading it up for the first time, you basically hit a brick wall thats going to be rough to climb. It would be amazing if 9front could somehow add some climbing tools for first-time users, without actually giving up on its uniqueness. Sometimes, Plan 9 feels more like an experimental art project instead of the capable operating system that it is, and I feel like that chases people away. Which is a real shame.
- Anos: a hobby microkernel operating system written in C
Anos is a modern, opinionated, non-POSIX operating system (just a hobby, wont be big and professional like GNU-Linux) for x86_64 PCs and RISC-V machines. Anos currently comprises the STAGE3 microkernel, SYSTEM user-mode supervisor, and a base set of servers implementing the base of the operating system. There is a (WIP) toolchain for Anos based on Binutils, GCC (16-experimental) and Newlib (with a custom libgloss). ↫ Anos GitHub page Its written in C, runs on both x86-64 and RISC-V, and can run on real hardware too (but this hasnt been tested on RISC-V just yet). For the x86 side of things, its strictly 64 bit, and requires a Haswell (4th Gen) chip or higher.

This year sees 35 years since 2.11BSD was announced on March 14, 1991 itself a slightly late celebration of 20 years of the PDP-11 and January 2026 brought what looks to be the venerable 16-bit OSs biggest ever patch! Much of the 1.3 MB size is due to Anders Magnusson, well-known for his work on NetBSD and the Portable C Compiler. Since 2.11BSDs stdio was not ANSI compliant, hes ported from 4.4BSD. ↫ BigSneakyDuck at Reddit Theres an incredible amount of work in here on this old variant of BSD, including fixes for old bugs and tons of other changes. This, the 499th patch for 2.11BSD, is so big, in fact, that vi on 2.11BSD cant handle the size of the files, so youre going to need to cut them up with sed, for which instructions are included. Its quite unique to see such a big update on the 35th anniversary of an operating system.
- Linux Kernel Developers Adopt New Fuzzing Tools
by George Whittaker
The Linux kernel development community is stepping up its security game once again. Developers, led by key maintainers like Greg Kroah-Hartman, are actively adopting new fuzzing tools to uncover bugs earlier and improve overall kernel reliability.
This move reflects a broader shift toward automated testing and AI-assisted development, as the kernel continues to grow in complexity and scale.
What Is Fuzzing and Why It Matters
Fuzzing is a software testing technique that feeds random or unexpected inputs into a program to trigger crashes or uncover vulnerabilities.
In the Linux kernel, fuzzing has become one of the most effective ways to detect:
Memory corruption bugs Race conditions Privilege escalation flaws Edge-case failures in subsystems
Modern fuzzers like Syzkaller have already discovered thousands of kernel bugs over the years, making them a cornerstone of Linux security testing.
New Tools Enter the Scene
Recently, kernel maintainers have begun experimenting with new fuzzing frameworks and tooling, including a project internally referred to as “clanker”, which has already been used to identify multiple issues across different kernel subsystems.
Early testing has uncovered bugs in areas such as:
SMB/KSMBD networking code USB and HID subsystems Filesystems like F2FS Wireless and device drivers
The speed at which these issues were discovered suggests that these new tools are significantly improving bug detection efficiency.
AI and Smarter Fuzzing Techniques
One of the most interesting developments is the growing role of AI and machine learning in fuzzing.
New research projects like KernelGPT use large language models to:
Automatically generate system call sequences Improve test coverage Discover previously hidden execution paths
These techniques can enhance traditional fuzzers by making them smarter about how they explore the kernel’s behavior.
Other advancements include:
Better crash analysis and deduplication tools (like ECHO) Configuration-aware fuzzing to explore deeper kernel states Feedback-driven fuzzing loops for improved coverage
Together, these innovations help developers focus on the most meaningful bugs rather than sifting through duplicate reports.
Why This Shift Is Happening Now
The Linux kernel is one of the most complex software projects in existence. With millions of lines of code and contributions from thousands of developers, manually catching every bug is nearly impossible.

- GNOME 50 Reaches Arch Linux: A Leaner, Wayland-Only Future Arrives
by George Whittaker
Arch Linux users are among the first to experience the latest GNOME desktop, as GNOME 50 has begun rolling out through Arch’s repositories. Thanks to Arch’s rolling-release model, new upstream software like GNOME arrives quickly, giving users early access to the newest features and architectural changes.
With GNOME 50, that includes one of the most significant shifts in the desktop’s history.
A Major GNOME Milestone
GNOME 50, officially released in March 2026 under the codename “Tokyo,” represents six months of development and refinement from the GNOME community.
Unlike some previous versions, this release focuses less on dramatic redesigns and more on strengthening the foundation of the desktop, improving performance, modernizing graphics handling, and simplifying long-standing complexities.
For Arch Linux users, that translates into a more streamlined and future-ready desktop environment.
Goodbye X11, Hello Wayland-Only Desktop
The headline change in GNOME 50 is the complete removal of X11 support from GNOME Shell and its window manager, Mutter.
After years of gradual transition:
X11 sessions were first deprecated Then disabled by default And now fully removed in GNOME 50
This means GNOME now runs exclusively on Wayland, with legacy X11 applications handled through XWayland compatibility layers.
The result is a simpler, more modern graphics stack that reduces maintenance overhead and improves long-term performance and security.
Improved Graphics and Display Handling
GNOME 50 brings several key improvements to display and graphics performance:
Variable Refresh Rate (VRR) enabled by default Better fractional scaling support Improved compatibility with NVIDIA drivers Enhanced HDR and color management
These changes aim to deliver smoother animations, more responsive desktops, and better support for modern displays.
For gamers and users with high-refresh monitors, these upgrades are especially noticeable.
Performance and Responsiveness Gains
Beyond graphics, GNOME 50 includes multiple performance optimizations:
Faster file handling in the Files (Nautilus) app Improved thumbnail generation Reduced stuttering in animations Better resource usage across the desktop
These refinements make the desktop feel more responsive, particularly on systems with demanding workloads or multiple monitors.
New Parental Controls and Accessibility Features
GNOME 50 also expands its focus on usability and accessibility.

- MX Linux Pushes Back Against Age Verification: A Stand for Privacy and Open Source Principles
by George Whittaker
The MX Linux project has taken a firm stance in a growing controversy across the Linux ecosystem: mandatory age-verification requirements at the operating system level. In a recent update, the team made it clear, they have no intention of implementing such measures, citing concerns over privacy, practicality, and the core philosophy of open-source software.
As governments begin introducing laws that could require operating systems to collect user age data, MX Linux is joining a group of projects resisting the shift.
What Sparked the Debate?
The discussion around age verification stems from new legislation, particularly in regions like the United States and Brazil, that aims to protect minors online. These laws may require operating systems to:
Collect user age or date of birth during setup Provide age-related data to applications Enable content filtering based on age categories
At the same time, underlying Linux components such as systemd have already begun exploring technical changes, including storing birthdate fields in user records to support such requirements.
MX Linux Says “No” to Age Verification
In response, the MX Linux team has clearly rejected the idea of integrating age verification into their distribution. Their reasoning is rooted in several key concerns:
User privacy: Collecting age data introduces sensitive personal information into systems that traditionally avoid such tracking Feasibility: Implementing consistent, secure age verification across a decentralized OS ecosystem is highly complex Philosophy: Open-source operating systems are not designed to act as data collectors or gatekeepers
The developers emphasized that they do not want to burden users with intrusive requirements and instead encouraged concerned individuals to direct their efforts toward policymakers rather than Linux projects.
A Broader Resistance in the Linux Community
MX Linux is not alone. The Linux world is divided on how, or whether, to respond to these regulations.
Some projects are exploring compliance, while others are pushing back entirely. In fact, age verification laws have sparked:
Strong debate among developers and maintainers Concerns about enforceability on open-source platforms New projects explicitly created to resist such requirements
In some extreme cases, distributions have even restricted access in certain regions to avoid legal complications.
Why This Matters
At its core, this issue goes beyond a single feature, it raises fundamental questions about what an operating system should be.
Linux has long stood for:

- LibreOffice Drives Europe’s Open Source Shift: A Growing Push for Digital Sovereignty
by George Whittaker
LibreOffice is increasingly at the center of Europe’s push toward open-source adoption and digital independence. Backed by The Document Foundation, the widely used office suite is playing a key role in helping governments, institutions, and organizations reduce reliance on proprietary software while strengthening control over their digital infrastructure.
Across the European Union, this shift is no longer experimental, it’s becoming policy.
A Broader Movement Toward Open Source
Europe has been steadily moving toward open-source technologies for years, but recent developments show clear acceleration. Governments and public institutions are actively transitioning away from proprietary platforms, often citing concerns about vendor lock-in, cost, and data control.
According to recent industry data, European organizations are adopting open source faster than their U.S. counterparts, with vendor lock-in concerns cited as a major driver.
LibreOffice sits at the center of this trend as a mature, fully open-source alternative to traditional office suites.
LibreOffice as a Strategic Tool
LibreOffice isn’t just another productivity application, it has become a strategic component in Europe’s digital policy framework.
The software:
Is fully open source and community-driven Supports open standards like OpenDocument Format (ODF) Allows governments to avoid dependency on specific vendors Enables long-term control over data and infrastructure
These characteristics align closely with the European Union’s broader strategy to promote interoperability and transparency through open standards.
Government Adoption Across Europe
LibreOffice adoption is already happening at scale across multiple countries and sectors.
Examples include:
Germany (Schleswig-Holstein): transitioning tens of thousands of government systems to Linux and LibreOffice Denmark: replacing Microsoft Office in public institutions as part of a broader digital sovereignty initiative France and Italy: deploying LibreOffice across ministries and defense organizations Spain and local governments: adopting LibreOffice to standardize workflows and reduce costs
In some cases, migrations involve hundreds of thousands of systems, demonstrating that open-source office software is viable at national scale.

- From Linux to Blockchain: The Infrastructure Behind Modern Financial Systems
by George Whittaker
The modern internet is built on open systems. From the Linux kernel powering servers worldwide to the protocols that govern data exchange, much of today’s digital infrastructure is rooted in transparency, collaboration, and decentralization. These same principles are now influencing a new frontier: financial systems built on blockchain technology.
For developers and system architects familiar with Linux and open-source ecosystems, the rise of cryptocurrency is not just a financial trend, it is an extension of ideas that have been evolving for decades.
Open-Source Foundations and Financial Innovation
Linux has long demonstrated the power of decentralized development. Instead of relying on a single authority, it thrives through distributed contributions, peer review, and community-driven improvement.
Blockchain technology follows a similar model. Networks like Bitcoin operate on open protocols, where consensus is achieved through distributed nodes rather than centralized control. Every transaction is verified, recorded, and made transparent through cryptographic mechanisms.
For those who have spent years working within Linux environments, this architecture feels familiar. It reflects a shift away from trust-based systems toward verification-based systems.
Understanding the Stack: Nodes, Protocols, and Interfaces
At a technical level, cryptocurrency systems are composed of multiple layers. Full nodes maintain the blockchain, validating transactions and ensuring network integrity. Lightweight clients provide access to users without requiring full data replication. On top of this, exchanges and platforms act as interfaces that connect users to the underlying network.
For developers, interacting with these systems often involves APIs, command-line tools, and automation scripts, tools that are already integral to Linux workflows. Managing wallets, verifying transactions, and monitoring network activity can all be integrated into existing development environments.

This move aligns with Mozilla’s long-standing emphasis on user privacy and security.
Split View for Better Multitasking
Firefox 149 introduces a Split View mode, allowing users to display two web pages side by side within a single browser window. This feature is especially useful for:
Comparing documents or products Copying information between pages Research and multitasking workflows
Instead of juggling multiple tabs and windows, users can now work more efficiently in a single, organized view.
Tab Notes: A New Productivity Tool
Another standout feature is Tab Notes, available through Firefox Labs. This tool allows users to attach notes directly to individual tabs, making it easier to:
Keep track of research Save reminders tied to specific pages Organize ongoing tasks
This feature reflects a growing trend toward integrating lightweight productivity tools directly into the browser experience.
Smarter Browsing with Optional AI Features
Firefox 149 also expands its experimental AI-powered features, including tools that can assist with summarizing content, providing quick explanations, or helping users interact with web pages more efficiently.
Importantly, Mozilla is keeping these features optional and user-controlled, maintaining its focus on transparency and privacy.
Developer and Platform Updates
For developers, Firefox 149 includes updates to web standards and APIs. One example is improved support for HTML features like enhanced popover behavior, which helps developers build more interactive web interfaces.
As always, these under-the-hood changes help ensure Firefox remains competitive and standards-compliant.

- The Need for Cloud Security in a Modern Business Environment
by George Whittaker
Cloud systems are an emergent standard in business, but migration efforts and other directional shifts have introduced vulnerabilities. Where some attack patterns are mitigated, cloud platforms leave businesses open to new threats and vectors. The dynamic nature of these environments cannot be addressed by traditional security systems, necessitating robust cloud security for contemporary organizations.
Just as businesses have come to acknowledge the value of cloud operations, so too have cyber attackers. Protecting sensitive assets and maintaining regulatory compliance, while simultaneously ensuring business continuity against cloud attacks, requires a modern strategy. When any window could be an opportunity for infiltration, a comprehensive approach serves to limit exploitation.
Unlike traditional on-premise infrastructure, cloud environments dramatically expand an organization’s threat surface. Resources are distributed across regions, heavily dependent on APIs, and frequently created or decommissioned in minutes. This constant change makes it difficult to maintain a fixed security perimeter and increases the likelihood that misconfigurations or exposed services go unnoticed, creating opportunities for exploitation.
The Vulnerabilities of Cloud Security Services
Any misconfiguration, insecure application programming interface (API), or identity management solution may become an invitation for cyberattacks. Amid the rise of artificial intelligence (AI) technology, it is possible for even inexperienced individuals to exploit such weaknesses in cloud systems. Cloud environments are designed for accessibility, a benefit that can be taken advantage of.
“Unlike traditional software, AI systems can be manipulated through language and indirect instructions,” Lee Chong Ming wrote for Business Insider. “[AI expert Sander] Schulhoff said people with experience in both AI security and cybersecurity would know what to do if an AI model is tricked into generating malicious code.”
At the same time that many businesses are migrating to cloud platforms and implementing cloud security features, they are adopting AI technology in order to accelerate workflows and other processes. These systems may have their advantages for certain industries, but their presence can create its own vulnerabilities. Addressing the shortcomings of cloud systems and AI at the same time compounds the security challenges of today.

- Google Brings Chrome to ARM Linux: A Long-Awaited Step for Modern Linux Devices
by George Whittaker
Google has officially announced that Chrome is coming to ARM64 Linux systems, marking a major milestone for both the Linux and ARM ecosystems. The native browser is expected to launch in Q2 2026, finally closing a long-standing gap for users running Linux on ARM-based hardware.
For years, ARM Linux users have relied on Chromium builds or workarounds to access a Chrome-like experience. That’s about to change.
Why This Announcement Matters
Until now, Google Chrome on Linux was limited to x86_64 systems, leaving ARM-based devices without an official build.
That meant users had to:
Use Chromium instead of Chrome
Run emulated versions of Chrome
Miss out on proprietary features like sync, DRM support, and Google services
With this new release, ARM Linux users will finally get the full Chrome experience, including seamless integration with Google’s ecosystem.
What Users Can Expect
The upcoming ARM64 version of Chrome will bring the same features users expect on other platforms:
Google account sync (bookmarks, history, tabs)
Access to the Chrome Web Store and extensions
Built-in features like translation, autofill, and security protections
Support for DRM services and media playback
This brings ARM Linux closer to feature parity with macOS (ARM support since 2020) and Windows on ARM (since 2024).
The Rise of ARM on Linux
The timing of this move reflects a broader shift in computing. ARM-based hardware is rapidly gaining traction across:
Laptops powered by Snapdragon and future ARM chips
Developer boards like Raspberry Pi
High-performance systems such as NVIDIA’s ARM-based AI desktops
Google itself highlighted growing demand for Chrome on these systems, especially as ARM expands beyond mobile devices into mainstream computing.
Partnerships and Deployment
Google is also working with hardware vendors to streamline adoption. Notably, Chrome will be integrated into NVIDIA’s Linux-on-ARM DGX Spark systems, making installation easier for high-performance AI workstations.
For general users, Chrome will be available for download directly from Google once released.
Why This Took So Long
Interestingly, this move comes years after Chrome was already available on ARM-based platforms like Apple Silicon Macs and Windows devices.

- CrackArmor Exposed: Critical Flaws in AppArmor Put Millions of Linux Systems at Risk
by George Whittaker
A newly disclosed set of vulnerabilities has sent shockwaves through the Linux security community. Dubbed “CrackArmor,” these flaws affect AppArmor, one of the most widely used security modules in Linux, potentially exposing millions of systems to serious compromise.
Discovered by the Qualys Threat Research Unit, the vulnerabilities highlight a concerning reality: even core security mechanisms can harbor weaknesses that go unnoticed for years.
What Is CrackArmor?
“CrackArmor” refers to a group of nine critical vulnerabilities found in the Linux kernel’s AppArmor module. AppArmor is a mandatory access control (MAC) system designed to restrict what applications can do, helping contain attacks and enforce system policies.
These flaws stem from a class of issues known as “confused deputy” vulnerabilities, where a lower-privileged user can trick trusted processes into performing actions on their behalf.
Why These Vulnerabilities Are Serious
The impact of CrackArmor is significant because it undermines one of Linux’s core security layers. Researchers found that attackers could:
Escalate privileges to root from an unprivileged account
Bypass AppArmor protections entirely
Break container isolation, affecting Kubernetes and cloud workloads
Execute arbitrary code in the kernel
Trigger denial-of-service (DoS) conditions
In some demonstrations, attackers were able to gain full root access in seconds under controlled conditions.
How Widespread Is the Risk?
The scope of the issue is massive. AppArmor is enabled by default in major distributions such as:
Ubuntu
Debian
SUSE
Because of this, researchers estimate that over 12.6 million Linux systems could be affected.
These systems span:
Enterprise servers
Cloud infrastructure
Containers and Kubernetes clusters
IoT and edge devices
This widespread deployment significantly amplifies the potential impact.
A Long-Standing Problem
One of the most concerning aspects of CrackArmor is how long the vulnerabilities have existed. According to researchers, the flaws date back to around 2017 (Linux kernel 4.11) and remained undiscovered in production environments for years.
This long exposure window increases the risk that similar weaknesses may exist elsewhere in critical system components.
