It's FOSS interviewed a software engineer whose long-running open source contributions include Python code for the Arch Linux installer and maintaining packages for NixOS. But "a recent change he made to systemd has pushed him into the spotlight" after he'd added the optional birthDate field for systemd's user database: Critics saw it not merely as a technical addition, but as a symbolic capitulation to government overreach. A crack in the philosophical foundation of freedom that Linux is built on. What followed went far beyond civil disagreement. Dylan revealed that he faced harassment, doxxing, death threats, and a flood of hate mail. He was forced to disable issues and pull request tabs across his GitHub repositories... Q: Should FOSS projects adapt to laws they fundamentally disagree with? Because these kinds of laws are certainly in conflict with what a lot of Linux users believe in. A. Unfortunately, in a lot of cases, the answer is yes — at least for any distribution with corporate backing. The small independent distributions are much more flexible to refuse as a protest. If we ignore regulations entirely, we risk Linux being something that companies are not willing to contribute to, and Linux may be shipped on less hardware. I'm talking about things like Valve and System76 (despite them very vocally hating these laws). That does not help us; it just lowers the quality of software contributions due to less investment in the platform and makes Linux less accessible to the average person. We need Linux and other free operating systems to remain a viable alternative to closed systems. Q. Do you think regulations like these will reshape desktop Linux in the next 5-10 years where we might have "compliant Linux" and "Freedom-first Linux"? A. Unfortunately, yes, to some degree this is likely. I imagine the split will be mostly along the lines of independent distributions and those with corporate backing. We're already seeing it as far as which distributions plan on implementing some sort of age verification and which ones are not, and that sucks. I'd rather nobody have to deal with this mess at all, but this is the reality of things now. As I said in the previous response, the corporate-backed distributions really have no choice in the matter. Companies are notoriously risk-adverse, but something like Artix or Devuan? Those are small and independent enough where the individual maintainers may be willing to take on more risk. I was actually thinking about what this would look like if we added it to [Linux system installer] Calamares and chatting about that with the maintainers before that thread got brigaded by bad actors posting personal information and throwing around insults. I completely support the freedom for the distro maintainers to choose their risk tolerance. If the distribution is based out of Ireland or something (like Linux Mint) without these silly laws in the jurisdiction the developer operates in, I think that we should leave it up to them to make a choice here. They think the installer should have a date picker with a flag to disable it, and "We can even default it to off, and corporate distributions using Calamares or those not willing to take the risk could flip it on if they need to. That way if maintainers of the distributions do not wish to collect the birth date, they won't have to, and no forking is required to patch it out."

"IBM says its quantum computer can now simulate real magnetic materials and match actual lab experiment results," writes Slashdot reader BrianFagioli, "which is something people have been waiting years to see." Instead of just theoretical output, the system reproduced neutron scattering data from a known material, meaning it lines up with real world physics. It still relies on a mix of quantum and classical computing and this is a narrow use case for now, but it is one of the first times quantum hardware has produced results that scientists can directly validate against experiments, which makes it a lot more interesting than the usual hype. Classical computers "are not great at modeling quantum systems," according to this article at Nerds.xyz. "The math gets messy fast, and scientists end up relying on approximations... Quantum computers are supposed to solve that problem..." If this direction continues, it could start to matter in areas like superconductors, battery tech, and even drug development. Those are the kinds of problems where better simulations can actually lead to better outcomes, not just nicer charts in a research paper. "I am extremely excited about what this means for science," said study co-author Allen Scheie from the Los Alamos National Laboratory. In an announcement from IBM, Scheie calls this "the most impressive match I've seen between experimental data and qubit simulation, and it definitely raises the bar for what can be expected from quantum computers."

Memory and storage shortages and price hikes have "steadily rippled outward across all kinds of consumer tech," reports Ars Technica. "Today's bad news comes from Sony, which is raising prices for PlayStation 5 consoles in the US just eight months after their last price hike." The drive-less Digital Edition will increase from $500 to $600; the base PS5 with an optical drive will increase from $550 to $650; and the PS5 Pro is going up from $750 to a whopping $900. At the beginning of 2025, these consoles cost $450, $500, and $700, respectively... RAM and flash memory chips are in short supply primarily because of demand from AI data centers — memory manufacturers have shifted more production toward making the kind of memory found in AI accelerators like Nvidia's H200, leaving less for the consumer market. And the situation is unlikely to improve any time soon, barring a major shift in demand from the AI industry.

In a new 4,000-word article, CNN tells the story of a retired appellate paralegal and grandmother in her early 70s who was treated for depression with psilocybin. CNN notes there's now retreats featuring psilocybin in a few countries — and while psilocybin is illegal under United States federal law, "In Oregon, 5,935 clients received psilocybin services through Oregon's state-regulated program in 2025." High doses of psilocybin are effective in treating depression, a growing body of research suggests, with promise for other conditions, like PTSD and addiction, said Dr. Albert Garcia-Romeu, associate director of the Center for Psychedelic and Consciousness Research at Johns Hopkins University... Some researchers suggest it disrupts entrenched traffic patterns in the brain or grows new neuron connections to change thinking. Others say the results from psilocybin could have to do with its anti-inflammatory effect, Garcia-Romeu said... Colorado became the second state to make psilocybin legal with a 2023 law and issued its first healing center" last year. A law adopted in New Mexico last year established that state's Medical Psilocybin Program, now in development... Psilocybin seems to be "knocking on the door of FDA approval," said Dr. Lynn Marie Morski, president of the Psychedelic Medicine Association, which educates health care providers on the therapeutic use of psychedelics so they can answer patients' questions through the lenses of clinical evidence and harm reduction. Psilocybin therapy first received a "breakthrough therapy" designation for treatment-resistant depression from the US Food and Drug Administration in 2018, and now psilocybin drug products are on track to be submitted to the FDA for possible approval in the not-too-distant future. While psilocybin is illegal under United States federal law, more states are creating their own paths for legal use under state laws.

Linux kernel maintainer Greg Kroah-Hartman tells The Register that AI-driven code review has "really jumped" for Linux. "There must have been some inflection point somewhere with the tools..." "Something happened a month ago, and the world switched. Now we have real reports." It's not just Linux, he continued. "All open source projects have real reports that are made with AI, but they're good, and they're real." Security teams across major open source projects talk informally and frequently, he noted, and everyone is seeing the same shift. "All open source security teams are hitting this right now...." For now, AI is showing up more as a reviewer and assistant than as a full author of Linux kernel code, but that line is starting to blur. Kroah-Hartman has already done his own experiments with AI-generated patches. "I did a really stupid prompt," he recounted. "I said, 'Give me this,' and it spit out 60: 'Here's 60 problems I found, and here's the fixes for them.' About one-third were wrong, but they still pointed out a relatively real problem, and two-thirds of the patches were right." Mind you, those working patches still needed human cleanup, better changelogs, and integration work, but they were far from useless. "The tools are good," he said. "We can't ignore this stuff. It's coming up, and it's getting better...." [H]e said that for "simple little error conditions, properly detecting error conditions," AI could already generate dozens of usable patches today. The sudden increase in AI-generated reports and AI-assisted work has also spurred a parallel push to build AI into the kernel's own review infrastructure. A key piece of that is Sashiko, a tool originally developed at Google and now donated to the Linux Foundation. Kroah-Hartman said some patches are being generated with AI now. "You have a little co-develop tag for that now. We're seeing some things for some new features, but we're seeing AI mostly being used in the review."

After decades of studying, this week NASA announced "a major step forward in bringing nuclear power and propulsion from the lab to space." NASA will launch the Space Reactor-1 Freedom, the first nuclear powered interplanetary spacecraft, to Mars before the end of 2028, demonstrating advanced nuclear electric propulsion in deep space. Nuclear electric propulsion provides an extraordinary capability for efficient mass transport in deep space and enables high power missions beyond Jupiter where solar arrays are not effective. Steven Sinacore, NASA's program executive for Fission Surface Power who will also oversee the SR-1 Freedom mission, emphasized to CNN that "On the ground the reactor is off. There's no radiation coming from it. It doesn't actually turn on until you're up in space, and that's where the radiation comes from." NASA says they aim to develop the capabilities required "for sustained exploration beyond the Moon and eventual journeys to Mars and the outer solar system." And Space Reactor-1 Freedom will carry a fleet of tiny helicopters (much like Ingenuity) to explore Mars, reports Space.com: Whereas Ingenuity was a technology demonstrator, however, the Skyfall fleet will have concrete tasks. Chief among them is scout: If all goes to plan, the little choppers will help NASA assess the potential of their target area (wherever that happens to be) to support human exploration. The Skyfall helicopters will carry cameras and ground-penetrating radar to scout a future landing site, to understand the slopes and hazards for human-scale landers," Steve Sinacore, the program executive for NASA's Space Reactors Office, said during the briefing. "They will also map and characterize the subsurface water ice to find out where the water ice deposits are, along with the size, depth and other important characteristics," he added... And that might not be the end of the line for SR-1 Freedom; NASA may decide to keep flying the spacecraft out into the solar system after it deploys the Skyfall choppers, according to Sinacore. The mission architecture, like much of NASA's exploration portfolio, is not yet finalized.

The Wall Street Journal reports: Walking into his kitchen, Tim Yoder recoiled at a message on his refrigerator door: "Shop Samsung water filters." Yoder, a supply-chain manager in Chicago, owns a Samsung Electronics Family Hub fridge. He paid $1,400 for an appliance that came with a 32-inch screen on the door that allows him to control other Samsung gadgets, pull up recipes or stream music. But since last fall, it's been intermittently serving up ads, part of a pilot program being tested on some of Samsung's smart fridges sold in the U.S. The response? Not warm. "I guess this is another place for somebody to shove an ad in your face," said the 47-year-old Yoder, recalling the first time he noticed one... The ads are only on certain Family Hub fridges that have screens and internet connectivity. They run as a rectangular banner at the bottom — part of a widget that also shows news, the weather and a calendar. Samsung declined to say how long the pilot might last or whether it would end. The firm recently unveiled a "Screens Everywhere" initiative that also includes washers, dryers and ovens.... Samsung launched the banner-type fridge ads that come as part of the widget via an October software update. In a footnote of a news release at the time, Samsung pledged to "serve contextual or non-personal ads" and respect data privacy. The banner ads can be turned off in settings. Samsung said the purpose of the pilot is to explore whether ads relevant to home chores can be useful to owners, and that overall pushback has been negligible. The "turn-off" rate for the pilot ad program remains in the bottom single-digit range, it said... While owners can turn off the banner ads, doing so eliminates the widget altogether, a bummer for Brian Bosworth, a media-industry engineer who liked the feature. Bosworth thinks it's wrong to take away the new feature as a condition. Wanting to keep the widget but not the ads, the 49-year-old in Edgewater, Md., made sure his home router's ad-blocking software extended to his fridge. He hasn't seen another since. One 27-year-old plans to return his refrigerator after the entire display "lit up with a full-screen ad for Apple TV's sci-fi show Pluribus," according to the article. The all-caps ad beckoned him "with an oft-used refrain directed at protagonist Carol Sturka: 'We're Sorry We Upset You, Carol.'" Thanks to Slashdot reader fjo3 for sharing the article.

Long-time Slashdot reader Qbertino writes: ... but the CERN Project "Antimatter in motion" just did it. For the first time in history researchers at CERN have transported 92 antiprotons on a truck in a specially designed magnetic enclosure. The test-drive went so well that the researchers spontaneously decided to go another round... The purpose of the experiment was to test the feasibility of transporting antimatter to other facilities in Europe to conduct further antimatter research. German news Tagesschau has a nice report. CNN reports that the antiproton enclosure was nearly six feet tall and weighed about 1,760 pounds. And Smithsonian magazine explains that it trapped the antiprotons in a vacuum chamber that had to be cooled to around -450 degrees Fahrenheit: Experts used a crane to carefully move the box of precious cargo from a lab onto a truck, which took about three hours, per the Associated Press' Jamey Keaten. Then, they drove the vehicle for roughly 30 minutes around CERN's campus, and subsequently returned the antiprotons to the lab. They worked with so little antimatter that even if it did touch ordinary matter and annihilate, it would release a small amount of energy detectable only by a special instrument, reports the AP.

A dog missing for two months was found at an animal shelter — and its owner received an email from an artificial intelligence service that identified it, according to the Washington Post. "As controversial as AI is right now, this is one of those areas where it's a real win," according to the chief executive at the nonprofit animal welfare organization Best Friends Animal Society. And while it shouldn't replace microchipping pets, AI does offer another tool to help desperate pet owners (and overcrowded animal shelters) — and might even be "game-changing"... People send photos of their lost pets to a database, and AI compares the pets' features — including facial structure, coat pattern and ear shape — to photos of stray pets that have been spotted elsewhere. Many of the stray pets have already been taken to shelters... Doorbell cameras have recently implemented facial recognition for dogs, and perhaps the largest AI database for pet reunification is Petco Love Lost, which says it has reunited more than 200,000 pets and owners since 2021... After owners upload photos of their lost pets, AI scans thousands of photos of lost animals from social media and from about 3,000 animal shelters and rescues that use the software, according to Petco Love, an animal welfare nonprofit that's affiliated with the pet store Petco. It notifies owners if two photos match. The article notes that one in three pets go missing during their lifetime, according to figures from the Animal Humane Society. "But as technology has progressed, so have resources for finding lost pets" — including GPS collars — and now, apparently, AI-powered pet identification.
