One of the often-requested LWN site features that has languished the longest on our to-do list is full-text RSS feeds. We are happy to announce that, finally, there is a set of such feeds available; the full set can be seen on our feeds page. This is a subscriber-only feature, and it works by creating a unique fetch URL for each user. We will, of course, be counting on our readers to not share those URLs.

Another feature we have had requests for is to automatically present the site in dark-mode colors when a reader's browser has been configured to prefer it. That feature, too, is now available. In this case, we had to think about the interaction between automatic selection and the color customization that the site has long had. The conclusion we reached is that, if custom colors have been configured for an account, they will win out over the automatic selection. There is a new preference in the customization area to change this default if desired.

Both of these features — and the other enhancements we have made recently — were enabled by the support of LWN's subscribers. By making it possible to bring in new staff last year, you created the space to improve the site experience while keeping up with the writing. We thank all of you for your support.

Version 25.2 of the Armbian Linux distribution for single-board computers (SBCs) has been released. Notable changes in this release include support for many new SBCs, an upgrade to Linux kernel 6.12.x, and more. See the changelog for a complete list.

More than 90% of UK undergraduate students now use AI in their studies, up from two-thirds a year ago, according to a Higher Education Policy Institute survey released Wednesday. The poll of 1,041 full-time undergraduates found 88% used generative AI such as ChatGPT for assessments, compared with 53% in 2024, with science students more likely to use the technology than humanities peers. Half of students cited "saving time" and "improving work quality" as their primary motivations. The proportion considering it acceptable to include AI-generated text after editing rose to 25% from 17% last year, while only 6% approved using AI content without editing. "Every assessment must be reviewed in case it can be completed easily using AI," said Josh Freeman, policy manager at Hepi. The report identified "persistent digital divides" in AI competency, with men and students from wealthier backgrounds more likely to be frequent users.

The Guardian: For some, the adverts that precede the start of a film are the bane of a trip to the cinema; for others, they are a useful buffer as you stand in the popcorn queue. But for one man in India, the lengthy marathon of cinema advertising was so infuriating that he took the matter to the courts -- and won. Abhishek MR, a 30-year-old man from the southern city of Bangalore, had booked a trip to the cinema with friends in December last year to watch wartime drama Sam Bahadur. But while the scheduled time he had booked the ticket for was 4.05pm, he had to sit through 25 minutes of adverts for upcoming features and commercial items such as homewares, mobile phones and cars before the film actually began. Having planned to return to work straight after the film, Abhishek MR was angered by what he felt was a costly disruption to his life. He filed a lawsuit against PVR Inox, India's largest cinema multiplex chain, stating that: "The complainant could not attend other arrangements and appointments which were scheduled for the day and has faced losses that cannot be calculated in terms of money as compensation." Bruce66423 adds: Great outcome -- and only 25 minutes of garbage punished. Note that Indian cinemas also make patrons sit through 15 minutes of adverts in the middle of the film.

The Faster CPython project has been working to speed up the Python interpreter for the past several years. Now, Ken Jin, a member of the project, has merged a new set of changes that have been benchmarked as improving performance by 10% for some architectures. The only change is switching from using computed goto statements to using tail calls as part of the implementation of Python's bytecode interpreter — but that change allows modern compilers to generate significantly better code.

Security updates have been issued by Fedora (crun, gnutls, libtasn1, and openssl), Mageia (emacs, gnutls, iniparser, kernel, kmod-virtualbox, kmod-xtables-addons, kernel-linus, krb5, libxml2, and vim), Slackware (tigervnc and xorg), SUSE (libprotobuf-lite28_3_0 and Maven), and Ubuntu (dropbear, kernel, libxml2, linux, linux-lowlatency, linux-lowlatency-hwe-6.8, linux, linux-lts-xenial, linux-aws-5.4 linux-raspi-5.4, linux-gcp, linux-gke, linux-gkeop, linux-ibm, linux-nvidia, linux-nvidia-6.8, linux-nvidia-lowlatency, linux-raspi, ProFTPD, python-virtualenv, rails, and xorg-server, xwayland).

British iPhone users have shown minimal reaction to Apple's decision to disable end-to-end encryption for UK iCloud customers, challenging the company's assumption about privacy priorities, a Bloomberg columnist notes. Rather than create a government-accessible backdoor demanded under Britain's Investigatory Powers Act, Apple chose to eliminate its Advanced Data Protection feature entirely for UK customers, effectively giving both authorities and potential hackers easier access to stored emails, photos and documents. The near absence of public outcry from British consumers points to what researchers call the "privacy paradox," where stated concerns about data security rarely translate to action. According to cited research, while 92% of American consumers believe they should control their online information, only 16% have stopped using services over data misuse. The quiet reception suggests Apple's principled stand against backdoors may have limited impact if customers don't understand or value encrypted protection, potentially undermining privacy's effectiveness as a marketing differentiator for the tech giant.

North Korean hackers have executed the largest cryptocurrency theft in history, draining $1.5 billion from Dubai-based exchange Bybit by compromising its multisignature cold wallet system. The attackers stole over 400,000 ethereum and staked ethereum coins without exploiting code vulnerabilities or infrastructure. Security researchers from Elliptic identified North Korean signatures in the subsequent laundering operations, consistent with the nation's ongoing cryptocurrency theft operations that fund its weapons programs. Investigators determined the hackers manipulated the user interfaces on multiple Bybit employees' devices simultaneously, tricking authorized personnel into approving what appeared to be legitimate transactions. This sophisticated attack "altered the smart contract logic and masked the signing interface," according to Bybit's disclosure. "The Bybit hack has shattered long-held assumptions about crypto security," noted researchers at Check Point. "No matter how strong your smart contract logic or multisig protections are, the human element remains the weakest link."

New research suggests that anthocyanins, the antioxidants responsible for the vibrant colors of fruits and flowers, may help counteract reproductive harm caused by microplastics. The Guardian reports: The new review of scientific literature on anthocyanins found that the compounds are probably protective against a range of plastic-induced impacts on hormones, reductions in testosterone and estrogen, decreased sperm counts, lower sperm quality, erectile dysfunction and ovarian damage. [...] Researchers said that mice exposed to microplastics, then treated with anthocyanins, showed increased sperm quality, including increased sperm count and motility, and the antioxidants overall reduced testicular damage. The new paper also pointed to research that found some microplastics reduce testosterone levels because they harm Leydig cells, which are responsible for the hormone's production. Anthocyanins seem to helped restore testosterone production and protect Leydig cells. In women, impacts on fertility and sexual development could be mitigated by anthocyanins that seem to protect hormone receptors from plastic chemicals such as bisphenol, phthalates and cadmium. The chemicals can mimic hormones, or cause hormonal responses. Microplastics in ovarian tissue cause inflammation that seems to lower levels of estrogen and other hormones. Research found that treating rats exposed to microplastics protected the ovarian tissue and normalized levels of estrogen and other hormones. "Its antioxidant properties help preserve ovarian function and potentially maintain fertility, highlighting its therapeutic potential in managing ovarian damage," the authors wrote.

Asteroid 2024 YR4, once considered a significant impact risk, has been reassigned to Torino Scale Level Zero and therefore poses no hazard to Earth. "The NASA JPL Center for Near-Earth Object Studies (CNEOS) now lists the 2024 YR4 impact probability as 0.00005 (0.005%) or 1-in-20,000 for its passage by Earth in 2032," Richard Binzel, Professor of Planetary Science at the Massachusetts Institute of Technology (MIT) and creator of the Torino scale exclusively told Space.com. "That's impact probability zero folks!" From the report: Discovered in Dec. 2024, 2024 YR4 quickly climbed to the top of NASA's Sentry Risk table, at one point having a 1 in 32 chance of hitting Earth. This elevated it to Level 3 on the Torino scale, a system used since 1999 to categorize potential Earth impact events. Level 3, which falls within the yellow band of the Torino Scale, is described as: "A close encounter, meriting attention by astronomers. Current calculations give a 1% or greater chance of collision capable of localized destruction." This conforms to the second part of the Torino scale level 3 description, which states: "Most likely, new telescopic observations will lead to re-assignment to Level 0. Attention by public and by public officials is merited if the encounter is less than a decade away." "Asteroid 2024 YR4 has now been reassigned to Torino Scale Level Zero, the level for 'No Hazard' as additional tracking of its orbital path has reduced its possibility of intersecting the Earth to below the 1-in-1000 threshold," Binzel continued. "1-in-1000 is the threshold established for downgrading to Level 0 for any object smaller than 100 meters; YR4 has an estimated size of 164 feet (50 meters)." [...] While 2024 YR4 poses no threat, it will still have a major scientific impact when it passes Earth in 2028 and again in 2032. On Dec. 17, the asteroid will come to within 5 million miles of Earth. Then, on Dec.22, 2032, 2024 YR4 will pass within just 167,000 miles of our planet. For context, the moon is 238,855 miles away.

An anonymous reader quotes a report from the New York Times: As investigators struggled for weeks to find who might have committed the brutal stabbings of four University of Idaho students in the fall of 2022, they were focused on a key piece of evidence: DNA on a knife sheath that was found at the scene of the crime. At first they tried checking the DNA with law enforcement databases, but that did not provide a hit. They turned next to the more expansive DNA profiles available in some consumer databases in which users had consented to law enforcement possibly using their information, but that also did not lead to answers. F.B.I. investigators then went a step further, according to newly released testimony, comparing the DNA profile from the knife sheath with two databases that law enforcement officials are not supposed to tap: GEDmatch and MyHeritage. It was a decision that appears to have violated key parameters of a Justice Department policy that calls for investigators to operate only in DNA databases "that provide explicit notice to their service users and the public that law enforcement may use their service sites." It also seems to have produced results: Days after the F.B.I.'s investigative genetic genealogy team began working with the DNA profiles, it landed on someone who had not been on anyone's radar:Bryan Kohberger, a Ph.D. student in criminology who has now been charged with the murders. The case has shown both the promise and the unregulated power of genetic technology in an era in which millions of people willingly contribute their DNA profiles to recreational databases, often to hunt for relatives. In the past, law enforcement officials would need to find a direct match between DNA at the crime scene and that of a specific suspect. Now, investigators can use consumer DNA data to build family trees that can zero in on a person of interest -- within certain policy limits.

Chinese robotics company Zhongqing Robotics (also known as Engine AI) posted a video of what is claimed to be the world's first humanoid robot front flip. New Atlas reports: Ten years ago, this kind of stuff simply did not exist. And now you can buy your very own open-source PM01 robot for US$13,700, according to EngineAI's website. Its specs aren't bad: 5-DoF (degrees of freedom) in each arm and six per leg. That's 23-DoF in body movement in total. The bot also boasts 221 lb-ft of torque (300 Nm), which seems like quite a punch when the little guy is only 4.5 ft (138 cm) tall and weighs 88 lb (40kg). You can watch the video here.

Denmark is set to ban mobile phones in schools and after-school clubs, following a government commission's recommendation that children under 13 should not have their own smartphones. The Guardian reports: The government said it would change existing legislation to force all folkeskole -- comprehensive primary and lower secondary schools -- to become phone-free, meaning that almost all children aged between seven and 16-17 will be required by law not to bring their phones into school. The announcement marks a U-turn by the government, which had previously refused to introduce such a law. It comes as governments across Europe are trying to impose tighter regulations on children's access to phones and social media. The Danish wellbeing commission was set up by the prime minister, Mette Frederiksen, in 2023 to investigate growing dissatisfaction among children and young people. Its long-awaited report, published on Tuesday, raised the alarm over the digitisation of children and young people's lives and called for a better balance between digital and analogue life. Among its 35 recommendations was the need for government legislation banning phones from schools and after-school clubs. The minister for children and education, Mattias Tesfaye, told Politiken: "There is a need to reclaim the school as an educational space, where there is room for reflection and where it is not an extension of the teenage bedroom." There will be scope for local authorities to make exceptions, including for children with special educational needs, but he said mobile phones and personal tablets "do not belong in school, neither during breaks nor during lessons." He said the government had started preparing a legislative amendment.

A massive blackout has hit Chile, leaving millions without power and disrupting transportation, businesses, and essential services across 14 of the country's 16 regions. The Associated Press reports: The National Electrical Coordinator, Chile's grid operator, said a disruption had occurred in a high-voltage transmission line that carries power from the Atacama Desert of northern Chile to the capital of Santiago in the country's central valley. It did not say what actually caused the disruption that pushed much of the country's power grid into shutdown, from the northernmost Chilean port of Arica to the southern Los Lagos agricultural region. Interior Minister Carolina Toha said hospitals, prisons and government buildings were switching on backup generators to keep essential equipment operating. In a press conference, Toha urged the public to stay calm and said officials were racing to put the grid back in operation and restore electric service across the country of some 19 million people. "It's affecting the entire electrical system of the country," she said of the breakdown in the 500-kV backbone transmission line. Toha said if all areas didn't return to normal by sunset the government would take emergency measures to avert a crisis. [...] Videos on social media from all over Chile, a long ribbon of a country stretching 4,300 kilometers (over 2,600 miles) along the southern Pacific coast, showed chaos at intersections with no functioning traffic lights, people having to use their mobile phones as torches in the underground metro and police dispatched to help evacuate office buildings.

An anonymous reader quotes a report from Gizmodo: As part of a settlement announced by the state of New York's Attorney General, Letitia James, DoorDash has agreed to pay $16.75 million to more than 60,000 Dashers who were supposed to receive that money in the form of tips but instead, the company used it to cover base pay and pocketed the rest. New York's lawsuit alleged that between May 2017 and September 2019, tens of thousands of Dashers were misled by DoorDash's pay model. At the time, the company offered a guaranteed wage to drivers -- the minimum amount that they could expect to make from a job. But instead of paying that guarantee and letting drivers keep their tips, DoorDash counted the tip toward their base pay and kept what was left. [...] Per the AG's lawsuit, DoorDash showed a message to customers that said "Dashers will always receive 100 percent of the tip" -- a statement that is technically true but does not clarify that "tip" is actually the delivery drivers' wage. New York argued that disclosures explaining how tips worked were buried in online documents and "customers had no way of knowing that DoorDash was using tips to reduce its own costs." DoorDash did eventually change its payment model to ensure "earnings will increase by the exact amount a customer tips on every order," but New York's case represents drivers finally getting those tips they earned during the period when the company was less transparent about who was actually pocketing that extra cash. Dashers eligible for the settlement will be contacted by the settlement administrator so they can get their piece of the pie that was rightfully theirs in the first place.

According to Bloomberg (paywalled), Warner Bros. Discovery announced today that it is shutting down three gaming studios and canceling development of its planned Wonder Woman project. Engadget reports: Monolith Productions, Player First Games and WB Games San Diego will be shuttered due to a "disappointing 2024" for WB's gaming business, according to an internal memo from JB Perrette, the company's CEO and president of global streaming and games. [...] According to the internal email from Perrette, WB's gaming efforts will be focused on four of its properties: Harry Potter (including Hogwarts Legacy), Mortal Kombat, the DC universe and Game of Thrones. "We need to make some substantial changes to our portfolio/team structure if we are to commit the necessary resources to get back to a "fewer but bigger franchises' strategy," Perette said.

At its "Second Gen" event today, Framework detailed three new computers: an updated Framework Laptop 13 with AMD Ryzen AI 300, a 4.5-liter Mini-ITX desktop powered by Ryzen AI Max, and a colorful, convertible Framework Laptop 12 designed with students in mind. The latter is defined by Framework as a "defining product." Tom's Hardware reports: Framework Desktop: The Framework Desktop is a 4.5L Mini-ITX machine using AMD's Ryzen AI Max "Strix Halo" chips with Radeon 8060S graphics. While this is a mobile chip, Framework says putting it in a desktop chassis gets it to 120W sustained power and 140W boost "while staying quiet and cool." Framework says this should allow 1440p gaming on intense titles, as well as workstation-class projects and local AI. [...] The base model, with a Ryzen AI Max 385 and 32GB of RAM, starts at $1,099, while the top-end machine with a Ryzen AI Max+ 395 with 128GB of RAM begins at $1,999. Framework is only doing "DIY" editions here, so you'll have to get your own storage drive and bring your own operating system (the company is calling it "the easiest PC you'll ever build"). The mainboard on its own will be available from $799. Pre-orders are open now, and Framework expects to ship sometime in Q3. Framework Laptop 12: The Laptop 12 is designed to bring the flexibility from the Laptop 12 but make it smaller, cheaper, and in more colors (with an optional stylus to match). These machines are made of ABS plastic molded in thermoplastic polyurethane, all around a metal frame. Framework says that it's "our easiest product ever to repair," but that more information on that will come closer to its launch in mid-2025. I'm really looking forward to this repair guide. It comes in five colorways: lavender, sage, gray, black, and bubblegum. The laptop will come with 13th Gen Intel Core i3 and i5 processors, which aren't the latest, but better than entry-level junk. You'll get up to 48GB of RAM, 2TB of storage, and Wi-Fi 6E. It has a 1920 x 1200 touch screen that the company claims will surpass 400 nits of brightness. There's no pricing information yet, and Framework says there's more to share on pricing and specs later in the year. Pre-orders will open in April ahead of the mid-year launch. Framework Laptop 13: The Framework Laptop 13 is getting a significant refresh with AMD Ryzen AI 300 Series. It doesn't look all that different on the outside, with a 13.5-inch design that largely resembles the one from way back in 2021. But there are new features. Beyond the processors, the Framework Laptop 3 is getting bumped up to Wi-Fi 7 and is getting a new thermal system, a "next-generation" keyboard, and new colorways for the Expansion Cards and bezels (though I still don't know why you would want a bezel in anything other than black). [...] The new Framework Laptop 13 with AMD Ryzen AI 300 starts at $899 for a DIY Edition without storage or an OS, and $1,099 for a pre-built model. If you're buying the mainboard to put in an old system, that's $449. (Framework is keeping the Ryzen 7040 systems around starting at $749). No word for now on any new Intel models.

An anonymous reader quotes a report from 9to5Google: Starting with the Snapdragon 8 Elite, Qualcomm will offer device manufacturers (OEMs) the "ability to provide support for up to eight consecutive years of Android software and security updates." Qualcomm today announced a "program" in partnership with Google: "What this means is that support for platform software included in this program will be made available to OEMs for eight consecutive years, including both Android OS and kernel upgrades, without requiring significant changes or upgrades to the platform and OEM code on the device (a separation commonly referred as 'Project Treble' or the 'vendor implementation'). While kernel changes will require updating kernel mode drivers, the vendor code can remain unchanged while the software support is being provided." This program specifically includes "two upgrades to the mobile platform's Android Common Kernel (ACK) to support the eight-year window." It's ultimately up to manufacturers to update their devices, but the bottleneck going forward won't be the chip. Qualcomm today notes how the extended software support it's providing can "lower costs for OEMs interested in supporting their devices longer." The first devices to benefit are Snapdragon 8 Elite-powered smartphones launching with Android 15. Notably, the program runs for the "next five generations" of SoCs, including Snapdragon 8 and 7-series chips launching "later this year." Older chipsets will not benefit from this program.

The conversation around the merging of a set of Rust abstractions for the kernel's DMA-mapping layer has mostly settled after Linus Torvalds made it clear that the code would be accepted. One other consequence of this decision, though, is that Christoph Hellwig has quietly stepped down from the maintenance of the DMA-mapping code. Marek Szyprowski will be the maintainer of that layer going forward. Hellwig has maintained that code for many years; his contributions will be missed.
