| 8:34p | Rust-Written Linux Scheduler Continues Showing Promising Results For Gaming "A Canonical engineer has been experimenting with implementing a Linux scheduler within the Rust programming language..." Phoronix reported Monday, "that works via sched_ext for implementing a scheduler using eBPF that can be loaded during run-time." The project was started "just for fun" over Christmas, according to a post on X by Canonical-based Linux kernel engineer Andrea Righi, adding "I'm pretty shocked to see that it doesn't just work, but it can even outperform the default Linux scheduler (EEVDF) with certain workloads (i.e., gaming)." Phoronix notes the a YouTube video accompanying the tweet shows "a game with the scx_rustland scheduler outperforming the default Linux kernel scheduler while running a parallel kernel build in the background." "For sure the build takes longer," Righi acknowledged in a later post. "This scheduler doesn't magically makes everything run faster, it simply prioritizes more the interactive workloads vs CPU-intensive background jobs." Righi followed up by adding "And the whole point of this demo was to prove that, despite the overhead of running a scheduler in user-space, we can still achieve interesting performance, while having the advantages of being in user-space (ease of experimentation/testing, reboot-less updates, etc.)" Wednesday Righi added some improvements, posting that "Only 19 lines of code (comments included) for ~2x performance improvement on SMT isn't bad... and I spent my lunch break playing Counter Strike 2 to test this patch..." And work seems to be continuing, judging by a fresh post from Righi on Thursday. "I fixed virtme-ng to run inside Docker and used it to create a github CI workflow for sched-ext that clones the latest kernel, builds it and runs multiple VMs to test all the scx schedulers. And it does that in only ~20min. I'm pretty happy about virtme-ng now."

| 9:34p | Billy Mitchell and Twin Galaxies Settle Lawsuits On Donkey Kong World Records "What happens when a loser who needs to win faces a winner who refuses to lose?" That was the tagline for the iconic 2007 documentary The King of Kong: A Fistful of Quarters, chronicling a middle-school teacher's attempts to take the Donkey Kong record from reigning world champion Billy Mitchell. "Billy Mitchell always has a plan," says Billy Mitchell in the movie (who is also shown answering his phone, "World Record Headquarters. Can I help you?") By 1985, 30-year-old Mitchell was already listed in the "Guinness Book of World Records" for having the world's highest scores for Pac-Man, Ms. Pac-Man, Donkey Kong, Donkey Kong, Jr., Centipede, and Burger Time. But then, NME reports... In 2018, a number of Mitchell's Donkey Kong high-scores were called into question by a fellow gamer, who supplied a string of evidence on the Twin Galaxies forums suggesting Mitchell had used an emulator to break the records, rather than the official, unmodified hardware that's typically required to keep things fair. [Twin Galaxies is Guiness World Records' official source for videogame scores.] Following "an independent investigation," Mitchell's hi-scores were removed from video game database Twin Galaxies as well as the Guinness Book Of Records, though the latter reversed the decision in 2020. Forensic analysts also accused him of cheating in 2022 but Mitchell has fought the accusations ever since. This week, 58-year-old Billy Mitchell posted an announcement on X. "Twin Galaxies has reinstated all of my world records from my videogame career... I am relieved and satisfied to reach this resolution after an almost six-year ordeal and look forward to pursuing my unfinished business elsewhere. Never Surrender, Billy Mitchell." X then wrote below the announcement, "Readers added context they thought people might want to know... Twin Galaxies has only reinstated Michell's scores on an archived leaderboard, where rules were different prior to TG being acquired in 2014. His score remains removed from the current leaderboard where he continues to be ineligible by today's rules." The statement from Twin Galaxies says they'd originally believed they'd seen "a demonstrated impossibility of original, unmodified Donkey Kong arcade hardware" in a recording of one of Billy's games. As punishment they'd then invalidated every record he'd ever set in his life. But now an engineer (qualified as an expert in federal courts) says aging components in the game board could've produced the same visual artifacts seen in the videotape of the disputed game. Consistent with Twin Galaxies' dedication to the meticulous documentation and preservation of video game score history, Twin Galaxies shall heretofore reinstate all of Mr. Mitchell's scores as part of the official historical database on Twin Galaxies' website. Additionally, upon closing of the matter, Twin Galaxies shall permanently archive and remove from online display the dispute thread... as well as all related statements and articles. NME adds: Twin Galaxies' lawyer David Tashroudian told Ars Technica that the company had all its "ducks in a row" for a legal battle with Mitchell but "there were going to be an inordinate amount of costs involved, and both parties were facing a lot of uncertainty at trial, and they wanted to get the matter settled on their own terms." And the New York Times points out that while Billy scored 1,062,800 in that long-ago game, "The vigorous long-running and sometimes bitter dispute was over marks that have long since been surpassed. The current record, as reported by Twin Galaxies, belongs to Robbie Lakeman. It's 1,272,800." Thanks to long-time Slashdot reader UnknowingFool for sharing the news.

| 10:34p | NPM Users Download 2.1B Deprecated Packages Weekly, Say Security Researchers The cybersecurity site SC Media reports that NPM registry users "download deprecated packages an estimated 2.1 billion times weekly, according to a statistical analysis of the top 50,000 most-downloaded packages in the registry." Deprecated, archived and "orphaned" NPM packages can contain unpatched and/or unreported vulnerabilities that pose a risk to the projects that depend on them, warned the researchers from Aqua Security's Team Nautilus, who published their findings in a blog post on Sunday... In conjunction with their research, Aqua Nautilus has released an open-source tool that can help developers identify deprecated dependencies in their projects. Open-source software may stop receiving updates for a variety of reasons, and it is up to developers/maintainers to communicate this maintenance status to users. As the researchers pointed out, not all developers are transparent about potential risks to users who download or depend on their outdated NPM packages. Aqua Nautilus researchers kicked off their analysis after finding that one open-source software maintainer responded to a report about a vulnerability Nautilus discovered by archiving the vulnerable repository the same day. By archiving the repository without fixing the security flaw or assigning it a CVE, the owner leaves developers of dependent projects in the dark about the risks, the researchers said... Taking into consideration both deprecated packages and active packages that have a direct dependency on deprecated projects, the researchers found about 4,100 (8.2%) of the top 50,000 most-downloaded NPM packages fell under the category of "official" deprecation. However, adding archived repositories to the definition of "deprecated" increased the number of packages affected by deprecation and deprecated dependencies to 6,400 (12.8%)... Including packages with linked repositories that are shown as unavailable (404 error) on GitHub increases the deprecation rate to 15% (7,500 packages), according to the Nautilus analysis. Encompassing packages without any linked repository brings the final number of deprecated packages to 10,600, or 21.2% of the top 50,000. Team Nautilus estimated that under this broader understanding of package deprecation, about 2.1 billion downloads of deprecated packages are made on the NPM registry weekly.

| 11:34p | Ultra-Large Structure Discovered In Distant Space Challenges Cosmological Principle "The discovery of a second ultra-large structure in the remote universe has further challenged some of the basic assumptions about cosmology," writes SciTechDaily: The Big Ring on the Sky is 9.2 billion light-years from Earth. It has a diameter of about 1.3 billion light-years, and a circumference of about four billion light-years. If we could step outside and see it directly, the diameter of the Big Ring would need about 15 full Moons to cover it. It is the second ultra-large structure discovered by University of Central Lancashire (UCLan) PhD student Alexia Lopez who, two years ago, also discovered the Giant Arc on the Sky. Remarkably, the Big Ring and the Giant Arc, which is 3.3 billion light-years across, are in the same cosmological neighborhood — they are seen at the same distance, at the same cosmic time, and are only 12 degrees apart on the sky. Alexia said: "Neither of these two ultra-large structures is easy to explain in our current understanding of the universe. And their ultra-large sizes, distinctive shapes, and cosmological proximity must surely be telling us something important — but what exactly? "One possibility is that the Big Ring could be related to Baryonic Acoustic Oscillations (BAOs). BAOs arise from oscillations in the early universe and today should appear, statistically at least, as spherical shells in the arrangement of galaxies. However, detailed analysis of the Big Ring revealed it is not really compatible with the BAO explanation: the Big Ring is too large and is not spherical." Other explanations might be needed, explanations that depart from what is generally considered to be the standard understanding in cosmology... And if the Big Ring and the Giant Arc together form a still larger structure then the challenge to the Cosmological Principle becomes even more compelling... Alexia said, "From current cosmological theories we didn't think structures on this scale were possible. " Possible explanations include a Conformal Cyclic Cosmology, or the effect of cosmic strings passing through... Thanks to long-time Slashdot reader schwit1 for sharing the article.
