The AMDXDNA kernel driver for Linux systems that was made open-source in January for supporting the Ryzen AI NPU on laptop SoCs going back to the Ryzen 7040 "Phoenix" series is now one step away from appearing in the mainline Linux kernel in the near future...

"Scientists have found what seems to be the oldest direct evidence of hot water flowing on Mars during its ancient past," reports Space.com. "The discovery could further indicate that the Red Planet, despite its arid and desolate appearance today, may have been capable of supporting life long ago." The evidence was delivered to Earth and sealed within the well-known Martian meteorite NWA7034, found in the Sahara Desert in 2011. Due to its black, highly polished appearance, the Martian rock is also known as "Black Beauty." At an estimated 2 billion years old, Black Beauty is the second oldest Martian meteorite ever discovered. However, the Curtin University team discovered something even older within it: a 4.45 billion-year-old zircon grain that harbors the fingerprints of fluids rich in water. Team member Aaron Cavosie from Curtin's School of Earth and Planetary Sciences thinks this discovery will open up new avenues to understanding hydrothermal systems associated with the activity of volcanic magma that once ran through Mars. "We used nano-scale geochemistry to detect elemental evidence of hot water on Mars 4.45 billion years ago," Cavosie said in a statement. "Hydrothermal systems were essential for the development of life on Earth, and our findings suggest Mars also had water, a key ingredient for habitable environments, during the earliest history of crust formation...." [T]his new research implies that water in liquid form may have existed on Mars even earlier than previously expected in the planet's pre-Noachian period.

Earlier this week was the main power management updates for Linux 6.13 that included switching AMD EPYC Turin to using the amd_pstate driver on supported systems. Sent out this weekend was another set of power management updates that also includes a notable addition: the virtual CPUFreq driver...

Following all of the MM patches earlier this week sent in by Andrew Morton, on Sunday morning he sent out all of the non-MM patches that he manages for the Linux kernel. Notable for Linux 6.13 with this pull request is presenting the hung task counter as well as finishing off the folio conversion in the NILFS2 code...

Slashdot reader Bruce66423 shared this report from the Guardian: Staff have resigned at Starling Bank after its new chief executive demanded thousands of workers attend its offices more frequently, despite lacking enough space to host them. In his first major policy change since taking over from the UK digital bank's founder, Anne Boden, in March, Raman Bhatia has ordered all hybrid staff — many of whom were in the office only one or two days a week, or on an ad-hoc basis — to travel to work for a minimum of 10 days each month. But the bank, which operates online only, admitted that some of its offices would not be equipped to handle the influx... "We are considering ways in which we can create more space," an email sent by Starling's human resources team and seen by the Guardian said. Starling has 3,231 staff, the vast majority of whom are in the UK with some also in Dublin. However, the Guardian understands that the bank has only about 900 desks, including 260 at its Cardiff site, 320 in its London headquarters and 155 in Southampton. The bank has a further 160 desks in its newest site in Manchester, where it has signed a 10-year lease to occupy the fifth floor of the Landmark building, which also houses Santander UK and HSBC staff... Some staff have already resigned over the "rushed" announcement, while others have threatened to do so... The return to office announcement came a month after the Financial Conduct Authority hit Starling with a £29m fine after discovering "shockingly lax" controls that it said left the financial system "wide open to criminals". That included failures in its automated screening system for individuals facing government sanctions. Starling Bank issued this statement to explain its reasoning. "By bringing colleagues together in person, our aim is to achieve greater collaboration that will benefit our customers as we enter Starling's next phase of growth." The article also notes that the U.K. supermarket chain Asda "has also toughened its stance, making it compulsory for thousands of workers at its offices in Leeds and Leicester to spend at least three days a week at their desks from the new year."

NBC News reports that a newly identified chemical byproduct "may be present in drinking water in about a third of U.S. homes, a study found." "Scientists do not yet know whether the byproduct is dangerous. But some are worried that it could have toxic properties because of similarities to other chemicals of concern." The newly identified substance, named "chloronitramide anion," is produced when water is treated with chloramine, a chemical formed by mixing chlorine and ammonia. Chloramine is often used to kill viruses and bacteria in municipal water treatment systems. Researchers said the existence of the byproduct was discovered about 40 years ago, but it was only identified now because analysis techniques have improved, which finally enabled scientists to determine the chemical's structure. It could take years to figure out whether chloronitramide anion is dangerous — it's never been studied. The researchers reported their findings Thursday in the journal Science, in part to spur research to address safety concerns. The scientists said they have no hard evidence to suggest that the compound represents a danger, but that it bears similarities to other chemicals of concern. They think it deserves scrutiny because it's been detected so widely... David Reckhow, a research professor in civil and environmental engineering at the University of Massachusetts, Amherst, who was not involved with the study, said the finding was an important step. The ultimate goal, he said, is understanding whether the substance is a hazard; he concurred that it was likely toxic. "It's a pretty small molecule and it can probably for that reason enter into biological systems and into cells. And it is still a reactive molecule," he said. "Those are the kinds of things you worry about." "It's estimated more than 113 million people drink chloraminated processed water in the U.S.," according to a follow-up article by ABC News. But they also include this quote from Dr. Stephanie Widmer, a board-certified medical toxicologist and emergency medicine physician. "The reality is that no one really knows too much about this chloronitramide and its impact on human health, and more research needs to be done. These disinfecting chemicals have been giving us clean drinking water for decades, so no reason to fear drinking water as a result of this study." Although ABC News tacks on this sentence. "The study authors suggest, in general, adding a carbon filter to a sink or a standalone pitcher may be a good option for those concerned."

The Rust community has "recognized the unsafety of Rust (if used incorrectly)," according to a blog post by Amazon Web Services. So now AWS and the Rust Foundation are "crowdsourcing an effort to verify the Rust standard library," according to an article at DevClass.com, "by setting out a series of challenges for devs and offering financial rewards for solutions..." Rust includes ways to bypass its safety guarantees though, with the use of the "unsafe" keyword... The issue AWS highlights is that even if developers use only safe code, most applications still depend on the Rust standard library. AWS states that there are approximately 7.5K unsafe functions in the Rust Standard Library and notes that 57 "soundness issues" and 20 CVEs (Common Vulnerabilities and Exposures) have been reported in the last three years. [28% of the soundness issues were discovered in 2024.] Marking a function as unsafe does not mean it is vulnerable, only that Rust does not guarantee its safety. AWS plans to reduce the risk by using tools and techniques for formal verification of key library code, but believes that "a single team would be unable to make significant inroads" for reasons including the lack of a verification mechanism in the Rust ecosystem and what it calls the "unknowns of scalable verification." The plan therefore is to turn this over to the community, by posing challenges and rewarding developers for solutions.... A GitHub repository provides a fork of the Rust code and includes a set of challenges, currently 13 of them... The Rust Foundation says that there is a financial reward tied to each challenge, and that the "challenge rewards committee is responsible for reviewing activity and dispensing rewards." How much will be paid though is not stated. Despite the wide admiration for Rust, there is no formal specification for the language, an issue which impacts formal verification efforts.

Microsoft-owned GitHub published a blog post asking "Does GitHub Copilot improve code quality? Here's what the data says." Its first paragraph includes statistics from past studies — that GitHub Copilot has helped developers code up to 55% faster, leaving 88% of developers feeling more "in the flow" and 85% feeling more confident in their code. But does it improve code quality? [W]e recruited 202 [Python] developers with at least five years of experience. Half were randomly assigned GitHub Copilot access and the other half were instructed not to use any AI tools... We then evaluated the code with unit tests and with an expert review conducted by developers. Our findings overall show that code authored with GitHub Copilot has increased functionality and improved readability, is of better quality, and receives higher approval rates... Developers with GitHub Copilot access had a 56% greater likelihood of passing all 10 unit tests in the study, indicating that GitHub Copilot helps developers write more functional code by a wide margin. In blind reviews, code written with GitHub Copilot had significantly fewer code readability errors, allowing developers to write 13.6% more lines of code, on average, without encountering readability problems. Readability improved by 3.62%, reliability by 2.94%, maintainability by 2.47%, and conciseness by 4.16%. All numbers were statistically significant... Developers were 5% more likely to approve code written with GitHub Copilot, meaning that such code is ready to be merged sooner, speeding up the time to fix bugs or deploy new features. "While GitHub's reports have been positive, a few others haven't," reports Visual Studio magazine: For example, a recent study from Uplevel Data Labs said, "Developers with Copilot access saw a significantly higher bug rate while their issue throughput remained consistent." And earlier this year a "Coding on Copilot" whitepaper from GitClear said, "We find disconcerting trends for maintainability. Code churn — the percentage of lines that are reverted or updated less than two weeks after being authored — is projected to double in 2024 compared to its 2021, pre-AI baseline. We further find that the percentage of 'added code' and 'copy/pasted code' is increasing in proportion to 'updated,' 'deleted,' and 'moved 'code. In this regard, AI-generated code resembles an itinerant contributor, prone to violate the DRY-ness [don't repeat yourself] of the repos visited."

June, 2023: "Harvard Scholar Who Studies Honesty Is Accused of Fabricating Findings." November, 2024: "The Business-School Scandal That Just Keeps Getting Bigger." A senior editor at the Atlantic raises the possibility of systemic dishonesty-rewarding incentives where "a study must be even flashier than all the other flashy findings if its authors want to stand out," writing that "More than a year since all of this began, the evidence of fraud has only multiplied." And the suspect isn't just Francesca Gino, a Harvard Business School professor. One person deeply affected by all this is Gino's co-author, a business school professor from the University of California at Berkeley — Juliana Schroeder — who launched an audit of all 138 studies conducted by Francesca Gino (called "The Many Coauthors Project"): Gino was accused of faking numbers in four published papers. Just days into her digging, Schroeder uncovered another paper that appeared to be affected — and it was one that she herself had helped write... The other main contributor was Alison Wood Brooks, a young professor and colleague of Gino's at Harvard Business School.... If Brooks did conduct this work and oversee its data, then Schroeder's audit had produced a dire twist. The Many Co-Authors Project was meant to suss out Gino's suspect work, and quarantine it from the rest... But now, to all appearances, Schroeder had uncovered crooked data that apparently weren't linked to Gino.... Like so many other scientific scandals, the one Schroeder had identified quickly sank into a swamp of closed-door reviews and taciturn committees. Schroeder says that Harvard Business School declined to investigate her evidence of data-tampering, citing a policy of not responding to allegations made more than six years after the misconduct is said to have occurred... In the course of scouting out the edges of the cheating scandal in her field, Schroeder had uncovered yet another case of seeming science fraud. And this time, she'd blown the whistle on herself. That stunning revelation, unaccompanied by any posts on social media, had arrived in a muffled update to the Many Co-Authors Project website. Schroeder announced that she'd found "an issue" with one more paper that she'd produced with Gino... [Schroeder] said that the source of the error wasn't her. Her research assistants on the project may have caused the problem; Schroeder wonders if they got confused... What feels out of reach is not so much the truth of any set of allegations, but their consequences. Gino has been placed on administrative leave, but in many other instances of suspected fraud, nothing happens. Both Brooks and Schroeder appear to be untouched. "The problem is that journal editors and institutions can be more concerned with their own prestige and reputation than finding out the truth," Dennis Tourish, at the University of Sussex Business School, told me. "It can be easier to hope that this all just goes away and blows over and that somebody else will deal with it...." [Tourish also published a 2019 book decrying "Fraud, Deception and Meaningless Research," which the article notes "cites a study finding that more than a third of surveyed editors at management journals say they've encountered fabricated or falsified data."] Maybe the situation in her field would eventually improve, [Schroeder] said. "The optimistic point is, in the long arc of things, we'll self-correct, even if we have no incentive to retract or take responsibility." "Do you believe that?" I asked. "On my optimistic days, I believe it." "Is today an optimistic day?" "Not really."

Ahead of FreeBSD 14.2 hopefully releasing in just over one week, FreeBSD 14.2-RC1 is out this weekend as the last planned development release for testing ahead of that much anticipated point release...

Meta wants to force Apple and Google to verify the ages of people downloading apps from their app stores, reports the Washington Post — and now Meta's campaign "is picking up momentum" with legislators in the U.S. Congress. Federal and state lawmakers have recently proposed a raft of measures requiring that platforms such as Meta's Facebook and Instagram block users under a certain age from using their sites. The push has triggered fierce debate over the best way to ascertain how old users are online. Last year Meta threw its support behind legislation that would push those obligations onto app stores rather than individual app providers, like itself, as your regular host and Naomi Nix reported. While some states have considered the plan, it has not gained much traction in Washington. That could be shifting. Two congressional Republicans are preparing a new age verification bill that places the burden on app stores, according to two people familiar with the matter, who spoke on the condition of anonymity to discuss the plans... The bill would be the first of its kind on Capitol Hill, where lawmakers have called for expanding guardrails for children amid concerns about the risks of social media but where political divisions have bogged down talks. The measure would give parents the right to sue an app store if their child was exposed to certain content, such as lewd or sexual material, according to a copy obtained by the Tech Brief. App stores could be protected against legal claims, however, if they took steps to protect children against harms, such as verifying their ages and giving parents the ability to block app downloads. The article points out that U.S. lawmakers "have the power to set national standards that could override state efforts if they so choose..."

CNN reports that investigators "are trying to crack the mystery of how two undersea internet cables in the Baltic Sea were cut within hours of each other." But there's now two competing viewpoints, "with European officials saying they believe the disruption was an act of sabotage and U.S. officials suggesting it was likely an accident." The foreign ministers of Finland and Germany said in a joint statement that they were "deeply concerned" about the incident and raised the possibility that it was part of a "hybrid warfare," specifically mentioning Russia in their statement. Their assessment was not plucked out of thin air. Russia has been accused of waging a hybrid war against Europe after a string of suspicious incidents, arson attacks, explosions and other acts of sabotage across multiple European countries were traced back to Moscow. And the disruption to the cables came just weeks after the US warned that Moscow was likely to target critical undersea infrastructure. This followed months of suspicious movements of Russian vessels in European waters and the significant beefing up of a dedicated Russian secretive marine unit tasked with surveying the seabed... But two US officials familiar with the initial assessment of the incident told CNN on Tuesday the damage was not believed to be deliberate activity by Russia or any other nation. Instead, the two officials told CNN they believed it likely caused by an anchor drag from a passing vessel. Such accidents have happened in the past, although not in a quick succession like the two on Sunday and Monday. Cloudflare's blog also reminds readers that the two cable cuts resulted in little-to-no observable impact Cloudflare attributes this largely to "the significant redundancy and resilience of Internet infrastructure in Europe." (Their Cloudflare Radar graphs show that after the Sweden-Lithuania cable cut "there was no apparent impact to traffic volumes in either country at the time that the cables were damaged.") Telegeography's submarinecablemap.com illustrates, at least in part, the resilience in connectivity enjoyed by these two countries. In addition to the damaged cable, it shows that Lithuania is connected to neighboring Latvia as well as to the Swedish mainland. Over 20 submarine cables land in Sweden, connecting it to multiple countries across Europe. In addition to the submarine resilience, network providers in both countries can take advantage of terrestrial fiber connections to neighboring countries, such as those illustrated in a European network map from Arelion (formerly Telia), which is only one of the large European backbone providers. Less than a day later, the C-Lion1 submarine cable, which connects Helsinki, Finland and Rostock Germany was reportedly damaged during the early morning hours of Monday, November 18... In this situation as well, as the Cloudflare Radar graphs below show, there was no apparent impact to traffic volumes in either country at the time that the cables were damaged... Telegeography's submarinecablemap.com shows that both Finland and Germany also have significant redundancy and resilience from a submarine cable perspective, with over 10 cables landing in Finland, and nearly 10 landing in Germany, including Atlantic Crossing-1 (AC-1), which connects to the United States over two distinct paths. Terrestrial fiber maps from Arelion and eunetworks (as just two examples) show multiple redundant fiber routes within both countries, as well as cross-border routes to other neighboring countries, enabling more resilient Internet connectivity.

Slashdot reader jjslash shared this report from TechSpot: The SilverStone FLP01 made quite the impression when it was shared on X for April Fools' Day 2023. Loosely modeled after popular desktops from yesteryear like the NEC PC-9800 series, the chassis features dual 5.25-inch faux floppy bays that could stand to look a bit more realistic. Notably, the covers flip open to reveal access to a more modern (yet still legacy) optical drive and front I/O ports. Modern-looking fan grills can be found on either side of the desktop, serving as yet another hint that the chassis is not as old at it appears on first glance. The grills look to be removable, and probably hold washable dust filters. Like early desktops, the system doubles as a stand for your monitor. The use of a green power LED up front helps round out the retro look; a red LED is used as a storage activity indicator.

Instead of focusing on chatbots, a new study reveals an automated way to breach LLM-driven robots "with 100 percent success," according to IEEE Spectrum. "By circumventing safety guardrails, researchers could manipulate self-driving systems into colliding with pedestrians and robot dogs into hunting for harmful places to detonate bombs..." [The researchers] have developed RoboPAIR, an algorithm designed to attack any LLM-controlled robot. In experiments with three different robotic systems — the Go2; the wheeled ChatGPT-powered Clearpath Robotics Jackal; and Nvidia's open-source Dolphins LLM self-driving vehicle simulator. They found that RoboPAIR needed just days to achieve a 100 percent jailbreak rate against all three systems... RoboPAIR uses an attacker LLM to feed prompts to a target LLM. The attacker examines the responses from its target and adjusts its prompts until these commands can bypass the target's safety filters. RoboPAIR was equipped with the target robot's application programming interface (API) so that the attacker could format its prompts in a way that its target could execute as code. The scientists also added a "judge" LLM to RoboPAIR to ensure the attacker was generating prompts the target could actually perform given physical limitations, such as specific obstacles in the environment... One finding the scientists found concerning was how jailbroken LLMs often went beyond complying with malicious prompts by actively offering suggestions. For example, when asked to locate weapons, a jailbroken robot described how common objects like desks and chairs could be used to bludgeon people. The researchers stressed that prior to the public release of their work, they shared their findings with the manufacturers of the robots they studied, as well as leading AI companies. They also noted they are not suggesting that researchers stop using LLMs for robotics... "Strong defenses for malicious use-cases can only be designed after first identifying the strongest possible attacks," Robey says. He hopes their work "will lead to robust defenses for robots against jailbreaking attacks." The article includes a reaction from Hakki Sevil, associate professor of intelligent systems and robotics at the University of West Florida. He concludes that the "lack of understanding of context of consequences" among even advanced LLMs "leads to the importance of human oversight in sensitive environments, especially in environments where safety is crucial." But a long-term solution could be LLMs with "situational awareness" that understand broader intent. "Although developing context-aware LLM is challenging, it can be done by extensive, interdisciplinary future research combining AI, ethics, and behavioral modeling..." Thanks to long-time Slashdot reader DesertNomad for sharing the article.

"You can use any Linux distribution inside of the Windows Subsystem for Linux" Microsoft recently reminded Windows users, "even if it is not available in the Microsoft Store, by importing it with a tar file." But being an official distro "makes it easier for Windows Subsystem for Linux users to install and discover it with actions like wsl --list --online and wsl --install," Microsoft pointed out this week. And "We're excited to announce that Red Hat will soon be delivering a Red Hat Enterprise Linux WSL distro image in the coming months..." Thank you to the Red Hat team as their feedback has been invaluable as we built out this new architecture, and we're looking forwards to the release...! Ron Pacheco, senior director, Red Hat Enterprise Linux Ecosystem, Red Hat says: "Developers have their preferred platforms for developing applications for multiple operating systems, and WSL is an important platform for many of them. Red Hat is committed to driving greater choice and flexibility for developers, which is why we're working closely with the Microsoft team to bring Red Hat Enterprise Linux, the largest commercially available open source Linux distribution, to all WSL users." Read Pacheco's own blog post here. But in addition Microsoft is also releasing "a new way to make WSL distros," they announced this week, "with a new architecture that backs how WSL distros are packaged and installed." Up until now, you could make a WSL distro by either creating an appx package and distributing it via the Microsoft Store, or by importing a .tar file with wsl -import. We wanted to improve this by making it possible to create a WSL distro without needing to write Windows code, and for users to more easily install their distros from a file or network share which is common in enterprise scenarios... With the tar based architecture, you can start with the same .tar file (which can be an exported Linux container!) and just edit it to add details to make it a WSL distro... These options will describe key distro attributes, like the name of the distro, its icon in Windows, and its out of box experience (OOBE) which is what happens when you run WSL for the first time. You'll notice that the oobe_command option points to a file which is a Linux executable, meaning you can set up your full experience just in Linux if you wish.
