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 shared this report from the Washington Post's "Tech Brief": Last fall, reports that Kroger was considering bringing facial recognition technology into its stores sparked outcry from lawmakers and customers. They worried personalized data could be used to charge different prices for different customers based on their shopping habits, financial circumstances or appearance. Kroger, the country's largest supermarket chain, had already been using digital price tags in its stores.

Kroger told lawmakers that it doesn't use facial recognition to help it set prices, a stance the company reiterated to the Tech Brief on Thursday. Still, the uproar helped to spark a push by consumer advocates who warn that the threat of invasive, personalized pricing schemes is real. Now, Democratic lawmakers in several states are working to ban so-called "surveillance pricing" — when businesses charge customers more or less for the same item based on their personal information.
Besides a bill in California, three more bill were introduced this month in Colorado, Georgia, and Illinois that also ban "surveillance wages," which the article defines as employers adjusting wages based on how much data an employee collects. "Both surveillance pricing and surveillance wages really disrupt fundamental ideals of fairness," University of California, Irvine law professor Veena Dubal tells the Washington Post.

Dubal is one of the consumer advocates behind a new report which notes information released last month by America's consumer-protecting FTC that "suggests that surveillance pricing tools are being actively developed and marketed across a range of industries, including consumer-facing businesses like 'grocery stores, apparel retailers, health and beauty retailers, home goods and furnishing stores, convenience stores, building and hardware stores, and general merchandise retailers such as department or discount stores." The consumer advocates (which include the Electronic Privacy Information Center) put it this way.

"Imagine walking into a grocery store and seeing a price for milk that's higher than what the next shopper pays because an algorithm calculated that you're willing to spend more..."

Deadline reports: It's taking around $1 billion to have 007 stewards Barbara Broccoli and Michael G. Wilson cede creative oversight of their family's storied James Bond franchise to Amazon MGM Studios, sources tell us. Amazon originally overpaid on its purchase of MGM in a deal orchestrated by then-MGM board chair Kevin Ulrich. Though valued between $3.5 billion-$4 billion, the legendary motion picture studio was absorbed by the streamer for $8.5 billion, the hefty sum propped up by the potential access of the 007 franchise. However, Amazon couldn't fully freely develop Bond with Broccoli and Wilson in the mix. Hence, it took another $1 billion to ensure that they could fully steer and exploit the Ian Fleming IP.
The article suggests Broccoli's long hold-out came from "Amazon's desire to expand the James Bond franchise into its own universe akin to Marvel or Star Wars." In the past, filmmakers including Quentin Tarantino and Christopher Nolan have expressed an interest in putting their stamp on Bond; both however, required complete creative control, which wasn't possible under the reign of Broccoli and Wilson. Now, with the producers on the side, Amazon can move forward to attract a top-tier director.

Also available to come to life in the new deal finally are a slew of Bond villains and women in their own series or features. The last time an attempt was made to spin off the Bond franchise was in 2003 with a stand-alone movie about the spy's girlfriend Jinx, played by Halle Berry in Die Another Day. Bond scribes Neal Purvis and Rob Wade were attached to pen that, with Stephen Frears circling, but Broccoli and Wilson put the kibosh to the idea due to creative differences.
In a related note, the article adds that Amazon "is looking to have an international theatrical distribution arm fully operational by some time in 2026."

Jeff Bezos asked his followers on X.com who should play James Bond in the next movie, reports IGN, "and the answer was loud and clear." On X.com the "clear fan favorite" was DC Extended Universe actor Henry Cavill. (Besides playing Superman, Cavill also appeared in the 2024 film spy action-comedy Argyle, and fought Tom Cruise's character in 2018's Mission Impossible: Fallout — and played Geralt of Rivia in the Netflix series The Witcher.)

The SS United States, a historic ocean liner that once held the transatlantic speed record of 36 knots (41 mph / 66 kph), has departed Philadelphia to be transformed into the world's largest artificial reef off Florida's Gulf Coast. The move is part of a $10 million project to boost tourism by creating a unique diving attraction while preserving the ship's legacy as a symbol of American innovation and engineering. The Associated Press reports: The SS United States, a 1,000-foot vessel that shattered the transatlantic speed record on its maiden voyage in 1952, is being towed to Mobile, Alabama, for planned prep work before officials eventually sink it off Florida's Gulf Coast. The move comes about four months after the conservancy that oversees the ship and its landlord resolved a years-old rent dispute. Officials initially planned to move the vessel last November, but that was delayed due to concerns from the U.S. Coast Guard that the ship wasn't stable enough to make the trip.

Officials in Okaloosa County on Florida's coastal Panhandle hope it will become a barnacle-encrusted standout among the county's more than 500 artificial reefs and a signature diving attraction that could generate millions of dollars annually in local tourism spending for scuba shops, charter fishing boats and hotels. Officials have said the deal to buy the ship could eventually cost more than $10 million. The lengthy process of cleaning, transporting and sinking the vessel is expected to take at least one-and-a-half years.

Nvidia has confirmed on its forums that the RTX 50 series GPUs no longer support 32-bit PhysX. Tom's Hardware reports: As far as we know, there are no 64-bit games with integrated PhysX technology, thus terminating the tech entirely on RTX 50 series GPUs and newer. RTX 40 series and older will still be able to run 32-bit CUDA applications and thus PhysX, but regardless, the technology is now officially retired, starting with Blackwell. [...]

The only way now to run PhysX on RTX 50 series GPUs (or newer) is to install a secondary RTX 40 series or older graphics card and slave it to PhysX duty in the Nvidia control panel. As far as we are aware, Nvidia has not disabled this sort of functionality. But the writing is on the wall for PhysX, and we doubt there will be any future games that attempt to use the API.

For over a decade Karol Herbst has been a developer on the open-source Nouveau driver, a reverse-engineered NVIDIA graphics driver for Linux. "He went on to become employed by Red Hat," notes Phoronix. "While he's known more these days for his work on the Mesa 3D Graphics Library and the Rusticl OpenCL driver for it, he's still remained a maintainer of the Nouveau kernel driver."

But Saturday Herbst stepped down as a nouveau kernel maintainer, in a mailing list message that begins "I was pondering with myself for a while if I should just make it official that I'm not really involved in the kernel community anymore, neither as a reviewer, nor as a maintainer." (Another message begins "I often thought about at least contributing some patches again once I find the time, but...")

Their resignation message hints at some long-running unhappiness. "I got burned out enough by myself caring about the bits I maintained, but eventually I had to realize my limits. The obligation I felt was eating me from inside. It stopped being fun at some point and I reached a point where I simply couldn't continue the work I was so motivated doing as I've did in the early days." And they point to one specific discussion on the kernel mailing list February 8th as "The moment I made up my mind."

It happened in a thread about whether Rust would create difficulty for maintainers. (Someone had posted that "The all powerful sub-system maintainer model works well if the big technology companies can employ omniscient individuals in these roles, but those types are a bit hard to come by.") In response, someone else had posted "I'll let you in a secret. The maintainers are not 'all-powerful'. We are the 'thin blue line' that is trying to keep the code to be maintainable and high quality. Like most leaders of volunteer organization, whether it is the Internet Engineerint Task Force (the standards body for the Internet), we actually have very little power. We can not *command* people to work on retiring technical debt, or to improve testing infrastructure, or work on some particular feature that we'd very like for our users. All we can do is stop things from being accepted..."

Saturday Herbst wrote: The moment I made up my mind about this was reading the following words written by a maintainer within the kernel community:

"we are the thin blue line"

This isn't okay. This isn't creating an inclusive environment. This isn't okay with the current political situation especially in the US. A maintainer speaking those words can't be kept. No matter how important or critical or relevant they are. They need to be removed until they learn. Learn what those words mean for a lot of marginalized people. Learn about what horrors it evokes in their minds.

I can't in good faith remain to be part of a project and its community where those words are tolerated. Those words are not technical, they are a political statement. Even if unintentionally, such words carry power, they carry meanings one needs to be aware of. They do cause an immense amount of harm.
The phrase thin blue line "typically refers to the concept of the police as the line between law-and-order and chaos," according to Wikipedia, but more recently became associated with a"countermovement" to the Black Lives Matter movement and "a number of far-right movements in the U.S."

Phoronix writes: Lyude Paul and Danilo Krummrich both of Red Hat remain Nouveau kernel maintainers. Red Hat developers are also working on developing NOVA as the new Rust-based open-source NVIDIA kernel driver leveraging the GSP interface for Turing GPUs and newer.

The Cleveland Review of Books ponders a new 697-page hardcover collection of American poet/author Kevin Killian's.... reviews from Amazon. (Over 2,000 of 'em — written over the course of 16 years.)
In 2012, he wrote three substantial paragraphs about the culinary perfection that can be found in a German Potato Salad Can (15 oz., Pack of 12). Often, he'd open with something like "as an American boy growing up in rural France." Killian grew up on Long Island, New York. He didn't take himself (or much else) too seriously....

[Killian] was also a member of the New Narrative Movement... Writers acknowledge the subjectivity of, and the author's active presence in, the text... Amazon reviews are a near-perfect vehicle for New Narrative's tenets... Killian camouflaged his reviews in the cadence of the Amazon everyman. He embraced all the stylistic quirks, choppy sentence fragments and run-ons, either darting from point to point like a distracted squirrel or leaning heavily into declarative statements.... About the biographer of Elia Kazan, he tells us, "Schickel is in love with the sound of his voice, and somewhere in the shredded coleslaw of his prose, a decent book lies unavailable to us, about the real Elia Kazan...."

[T]he writing can move from very funny to strangely poignant. One of my favorites, his review of MacKenzie Smelling Salts, begins with a tragically tongue-in-cheek anecdote about his Irish grandfather:

"My Irish grandfather used to keep a bottle of MacKenzie's smelling salts next to his desk. He was the principal at Bushwick High School (in Brooklyn, NY) in the 1930s and 1940s, before it became a dangerous place to live in, and way before Bushwick regained its current state of desirable area for new gentrification. And he kept one at home as well, in case of a sudden shock. At school, he would press the saturated cotton under the nostrils of poor girls who realized they were pregnant in health class, before he expelled them."

He ends with his own reasons for using smelling salts, citing wildly diverging examples: his grief upon learning of the death of Paul Walker from the Fast & Furious film franchise abuts Killian's disappointment at not being selected for the 2014 Whitney Biennial. Apparently, both were deeply traumatic experiences for Kevin... ["it took my wife a minute or two to locate the MacKenzie's, but passing it under my nose, as though she were my grandfather ministering to the pregnant girls of yore..."]

No one wants to be forgotten. I do not think it's a coincidence Killian started writing the reviews after his heart attack. Why did he keep going? Most likely, it was because he enjoyed the writing and got something out of it — pleasure, practice, and a bit of notoriety. But mainly, I think the project grew out of habit and compulsion. In a similar way, the graffiti art of Keith Haring, Jean-Paul Basquiat, and Banksy began in subway tunnels, one tag and mural at a time, until it grew into bodies of work collected and coveted by museums worldwide. In Killian's case, the global commerce platform was his ugly brick wall, his subway platform, and his train car. Coming away, I like to imagine him gleefully typing, manipulating the Amazon review forums into something that had little to do with the consumerism they had been created to support: Killian tagging a digital wall to remind everyone KEVIN WAS HERE.
The book reviewer points out that the collection's final review, for the memoir Never Mind the Moon: My Time at the Royal Opera House, is dated a month before Killian died.

"Unfortunately, the editors of this volume did not preserve the Helpful/Not Helpful ratings, only the stars."

Putting it all in perspective, the book critic notes that "In 2023, Amazon reported that one hundred million customers submitted one or more product reviews to the site. The content of most is dross, median." Though the critic then also acknowledges that "I haven't read any of Killian's other work."

Longtime Slashdot reader BrendaEM writes: Command-line aside, Cinnamon is the most effective keeper of the Linux desktop flame -- by not abandoning desktop and laptop computers. Yes, there are other desktop GUIs, such as MATE, and the lightweight Xfce, which are valuable options when low overhead is important, such as in LinuxCNC. However, among the general public lies a great expanse of office workers who need a full-featured Linux desktop.

The programmers who work on GNOME and its family of supporting applications enrich many other desktops do their more than their share. These faithful developers deserve better user-interface leadership. GNOME has tried to steer itself into tablet waters, which is admirable, but GNOME 3.x diminished the desktop experience for both laptop and desktop users. For instance, the moment you design what should be a graphical user interface with words such as "Activities," you ask people to change horses midstream. That is not to say that the command line and GUI cannot coexist -- because they can, as they do in many CAD programs.

I remember a time when GNOME ruled the Linux desktop -- and I can remember when GNOME left those users behind. Perhaps in a future, GNOME could return to the Linux desktop and join forces with Cinnamon -- so that we may once again have the year of the Linux desktop.

Astronomers have discovered a perfect ring of light in a galaxy 590 million light-years away. "The phenomenon is known as an Einstein ring, and it was discovered circumscribing the galaxy NGC 6505 in data collected by the European Space Agency's Euclid space telescope," reports SpaceAlert. From the report: [...] In the case of the newly discovered Einstein ring, the light that encircles the near galaxy is from a more distant galaxy, sitting some 4.42 billion light-years away, whose light has been warped by the curvature of space-time around NGC 6505. It's a very lucky arrangement of objects: they are aligned in such a way that the distant galaxy's light is stretched into a perfect ring, with brighter blobs representing replicated images of the galaxy at four points around the ring.

And the closeness of NGC 6505 makes it even more astonishing. Only five other lenses have been discovered so close; simulations suggest this new lens only had a 0.05 percent chance of existing, never mind being discovered. The more distant galaxy had never been seen before; now, scientists have the perfect tool to study it in greater detail than would be possible without the lens. The research has been published in Astronomy & Astrophysics.

They publish 77 newspapers in 26 U.S. states, according to Wikipedia. But this week a "cybersecurity event" at the newspapers' parent company "disrupted systems and networks," according to an article at one of their news sites which quotes an email sent to employees by the publishing company's CEO. "We have notified law enforcement of the situation."

And the company "has not released print or e-editions in most markets this week," according to the Augusta Free Press, "originally telling subscribers the outage was due to a server issue," The CEO said the company is also working to identify "additional steps we can take to help prevent something like this from happening again." The computer server appears to have compromised [last] Monday morning. No timeline has been announced for when news operations will return to normal publication schedules. According to a report in The News Virginian and published on the websites of the affected papers nationwide, the company is now producing, printing and delivering back issues, indicating at least some progress on printing and layout front...

Unfortunately, the cybersecurity attack on its server wasn't the only bad news for Lee Enterprises this week... In addition to the estimated $16.7 million the enterprise reported it lost in the last quarter, it has also gutted the staff of its newspapers as it appears to shift its focus toward more successful digital operations.

Fortune remembers that in 2011 Steve Jobs had told author Walter Isaacson that Microsoft co-founder Bill Gates would "be a broader guy if he had dropped acid once or gone off to an ashram when he was younger."

But The Indendepent notes that in his new memoir Gates does write about two acid trip experiences. (Gates mis-timed his first experiment with LSD, ending up still tripping during a previously-scheduled appointment for dental surgery...) "Later in the book, Gates recounts another experience with LSD with future Microsoft co-founder Paul Allen and some friends... Gates says in the book that it was the fear of damaging his memory that finally persuaded him never to take the drug again." He added: "I smoked pot in high school, but not because it did anything interesting. I thought maybe I would look cool and some girl would think that was interesting. It didn't succeed, so I gave it up."

Gates went on to say that former Apple CEO Steve Jobs, who didn't know about his past drug use, teased him on the subject. "Steve Jobs once said that he wished I'd take acid because then maybe I would have had more taste in my design of my products," recalled Gates. "My response to that was to say, 'Look, I got the wrong batch.' I got the coding batch, and this guy got the marketing-design batch, so good for him! Because his talents and mine, other than being kind of an energetic leader, and pushing the limits, they didn't overlap much. He wouldn't know what a line of code meant, and his ability to think about design and marketing and things like that... I envy those skills. I'm not in his league."

Gates added that he was a fan of Michael Pollan's book about psychedelic drugs, How To Change Your Mind, and is intrigued by the idea that they may have therapeutic uses. "The idea that some of these drugs that affect your mind might help with depression or OCD, I think that's fascinating," said Gates. "Of course, we have to be careful, and that's very different than recreational usage."
Touring the country, 69-year-old Gates shared more glimpses of his life story:

• The Harvard Gazette notes that the university didn't offer computer science degrees when Gates attended in 1973. But since Gates already had years of code-writing experience, he "initially rebuffed any suggestion of taking computer-related coursework... 'It's too easy,' he remembered telling friends."

• "The naiveté I had that free computing would just be this unadulterated good thing wasn't totally correct even before AI," Gates told an audience at the Harvard Book Store. "And now with AI, I can see that we could shape this in the wrong way."

• Gates "expressed regret about how he treated another boyhood friend, Paul Allen, the other cofounder of Microsoft, who died in 2018," reports the Boston Globe. "Gates at first took 60 percent ownership of the new software company and then pressured his friend for another 4 percent. 'I feel bad about it in retrospect,' he said. 'That was always a little complicated, and I wish I hadn't pushed....'"

• Business Insider adds that according to his memoir, Gates "eventually gave his additional 4% stake to [Steve] Ballmer to convince him to quit business school for Microsoft. 'He joined in 1980 and became the 24-hour-a-day partner I needed,' Gates wrote."

• Benzinga writes that Gates has now "donated $100 billion to charitable causes... Had Gates retained the $100 billion he has donated, his total wealth would be around $264 billion, placing him second on the global wealth rankings behind Elon Musk and ahead of Jeff Bezos and Mark Zuckerberg."

• Gates told the Associated Press "I am stunned that Intel basically lost its way," saying Intel is now "kind of behind" on both chip design and fabrication. "They missed the AI chip revolution, and with their fabrication capabilities, they don't even use standards that people like Nvidia and Qualcomm find easy... I hope Intel recovers, but it looks pretty tough for them at this stage."

• Gates also told the Associated Press that fighting a three-year antitrust case had "distracted" Microsoft. "The area that Google did well in that would not have happened had I not been distracted is Android, where it was a natural thing for me. I was trying, although what I didn't do well enough is provide the operating system for the phone. That was ours for the taking."

• The Dallas News reports that in an on-stage interview in Texas, Mark Cuban closed by asking Gates one question. "Is the American Dream alive?" Gates answered: "It was for me."

Slashdot has been covering Harvard's legendary introductory programming course "CS50" since it began setting attendance records in 2014.

But now long-time Slashdot reader theodp brings some news about the course's fate over at Yale. From Yale's student newspaper: After a decade of partnership with Harvard, Yale's CS50 course will no longer be offered starting in fall 2025.... One of Yale's largest computer science courses, jointly taught with Harvard University, was canceled during a monthly faculty meeting after facing budgetary challenges. [Yale's endowment is $40+ billion]... Since Yale started offering the course in 2015, CS50 has consistently seen enrollment numbers in the hundreds and was often the department's largest class.... According to [Yale instructor Ozan] Erat, the original [anonymous] donation that made CS50 possible ended in June 2024, and the cost of employing so many undergraduate learning assistants for the course had become unsustainable.
theodp reminds us that CS50 and its progeny "will continue to live on in all their glory in-person and online at Harvard and edX."

Long-time Slashdot reader Shayde once restored a 1986 DEC PDP-11 minicomputer, and even ran Turbo Pascal on a 40-year-old Apple II clone.

Now he's exploring a 27-year-old Macintosh PowerBook G3 — with 64 megabytes memory and 4 gigabytes of disk space. "The year is 1997, and Apple is in big trouble." (Apple's market share had dropped from 16% in 1980 to somewhere below 4%...) Turns out this was one of the first machines able to run OS X, and was built during the transition period for Apple after Steve Jobs came back in to rescue the company from bankruptcy.
It's clearly old technology. There's even a SCSI connector, PCMCIA sockets, a modem port for your phone/landline cable, and a CD-ROM drive. There's also Apple's proprietary ports for LocalTalk and an Apple Desktop Bus port ("used for keyboards, mice, and stuff like that"). And its lithium-ion batteries "were meant to be replaced and moved around, so you could carry spare batteries with you."

So what's it like using a 27-year-old laptop? "The first thing I had to note was this thing weighs a ton! This thing could be used as a projectile weapon! I can't imagine hauling these things around doing business..." And it's a good thing it had vents, because "This thing runs hot!" (The moment he plugs it in he can hear its ancient fan running...) It seems to take more than two minutes to boot up. ("The drive is rattling away...") But soon he's looking at a glorious desktop from 1998 desktop. ("Applications installed... Oh look! Adobe Acrobat Reader! I betcha that's going to need an update...")

After plugging in a network cable, a pop-up prompts him to "Set up your .Mac membership." ("I have so little interest in doing this.") He does find an old version of Safari, but it refuses to launch-- though "While puttering around in the application folder, I did notice that we had Internet Explorer installed. But that pretty much went as well as expected." In the end it seems like he ends up "on the network, but we have no browser." Although at least he does find a Terminal program — and successfully pings Google.

The thing that would drive me crazy is when opening the laptop, Apple's logo is upside-down!

An anonymous reader quotes a report from Ars Technica written by Kevin Purdy: There are only two licensed professional sports games included in Wikipedia's "List of video games notable for negative reception." Do not be fooled, however: WWE 2K20 and eFootball 2022 are just the outliers, arriving so poorly crafted as to cause notable outcry and an actual change to development plans. Most licensed professional sports games come out yearly, whether fully baked, notably improved, or not, and fans who have few other options to play with their favorite intellectual property learn to make do with them.

Not so with fans of Football Manager, a series that can be traced back in some form to 1992 that has released a game almost every year, minus one ownership shift in the early 2000s. Sports Interactive, the company behind the franchise, released a statement on Thursday (in British time) that says that "following extensive internal discussions and careful consideration," Football Manager 25 is canceled. The game was "too far away from the standards you deserve," so they are focusing on the 2026 version. [...]

The developer's statement notes that preorder customers are getting refunds. Answering a question that has always been obvious to fans but never publishers, the company notes that, no, Football Manager 2024 will not get an update with the new season's players and data. The company says it is looking to extend the 2024 version's presence on subscription platforms, like Xbox's Game Pass, and will "provide an update on this in due course." Fans eager to build out their dynasty team and end up with Bukayo Saka may be disappointed to miss out this year. But a developer with big ambitions to meaningfully improve and rethink a long-running franchise deserves some consideration amid the consternation.

Scientists have demonstrated control over a newly theorized type of magnetism, known as altermagnetism, by manipulating nanoscale magnetic whirlpools in an ultra-thin wafer of manganese telluride. "Our experimental work has provided a bridge between theoretical concepts and real-life realization, which hopefully illuminates a path to developing altermagnetic materials for practical applications," says University of Nottingham physicist Oliver Amin, who led the research with PhD student Alfred Dal Din. From the report: Using a device that accelerates electrons to blinding speeds, a team led by researchers from the University of Nottingham showered an ultra-thin wafer of manganese telluride with X-rays of different polarizations, revealing changes on a nanometer scale reflecting magnetic activity unlike anything seen before. [...] More recently, a third configuration of particles in ferromagnetic materials was theorized.

In what's referred to as altermagnetism, particles are arranged in a canceling fashion like antiferromagnetism, yet rotated just enough to allow for confined forces on a nanoscale -- not enough to pin a grocery list to your freezer, but with discrete properties that engineers are keen to manipulate into storing data or channeling energy. "Altermagnets consist of magnetic moments that point antiparallel to their neighbors," explains University of Nottingham physicist Peter Wadley. "However, each part of the crystal hosting these tiny moments is rotated with respect to its neighbors. This is like antiferromagnetism with a twist! But this subtle difference has huge ramifications."

Experiments have since confirmed the existence of this in-between 'alter' magnetism. However, none had directly demonstrated it was possible to manipulate its tiny magnetic vortices in ways that might prove useful. Wadley and his colleagues demonstrated that a sheet of manganese telluride just a few nanometers thick could be distorted in ways that intentionally created distinct magnetic whirlpools on the wafer's surface. "Our experimental work has provided a bridge between theoretical concepts and real-life realization, which hopefully illuminates a path to developing altermagnetic materials for practical applications," says University of Nottingham physicist Oliver Amin. This research was published in the journal Nature.

An anonymous reader writes: Low quality books that appear to be AI generated are making their way into public libraries via their digital catalogs, forcing librarians who are already understaffed to either sort through a functionally infinite number of books to determine what is written by humans and what is generated by AI, or to spend taxpayer dollars to provide patrons with information they don't realize is AI-generated.

Public libraries primarily use two companies to manage and lend ebooks: Hoopla and OverDrive, the latter of which people may know from its borrowing app, Libby. Both companies have a variety of payment options for libraries, but generally libraries get access to the companies' catalog of books and pay for customers to be able to borrow that book, with different books having different licenses and prices. A key difference is that with OverDrive, librarians can pick and choose which books in OverDrive's catalog they want to give their customers the option of borrowing. With Hoopla, librarians have to opt into Hoopla's entire catalog, then pay for whatever their customers choose to borrow from that catalog. The only way librarians can limit what Hoopla books their customers can borrow is by setting a limit on the price of books. For example, a library can use Hoopla but make it so their customers can only borrow books that cost the library $5 per use.

On one hand, Hoopla's gigantic catalog, which includes ebooks, audio books, and movies, is a selling point because it gives librarians access to more for cheaper price. On the other hand, making librarians buy into the entire catalog means that a customer looking for a book about how to diet for a healthier liver might end up borrowing Fatty Liver Diet Cookbook: 2000 Days of Simple and Flavorful Recipes for a Revitalized Liver. The book was authored by Magda Tangy, who has no online footprint, and who has an AI-generated profile picture on Amazon, where her books are also for sale. Note the earring that is only on one ear and seems slightly deformed. A spokesperson for deepfake detection company Reality Defender said that according to their platform, the headshot is 85 percent likely to be AI-generated. [...] It is impossible to say exactly how many AI-generated books are included in Hoopla's catalog, but books that appeared to be AI-generated were not hard to find for most of the search terms I tried on the platform. "This type of low quality, AI generated content, is what we at 404 Media and others have come to call AI slop," writes Emanuel Maiberg. "Librarians, whose job it is in part to curate what books their community can access, have been dealing with similar problems in the publishing industry for years, and have a different name for it: vendor slurry."

"None of the librarians I talked to suggested the AI-generated content needed to be banned from Hoopla and libraries only because it is AI-generated. It might have its place, but it needs to be clearly labeled, and more importantly, provide borrowers with quality information."

Sarah Lamdan, deputy director of the American Library Association, told 404 Media: "Platforms like Hoopla should offer libraries the option to select or omit materials, including AI materials, in their collections. AI books should be well-identified in library catalogs, so it is clear to readers that the books were not written by human authors.

The blog OMG Ubuntu reports: Ubuntu's key developers have agreed to switch to Matrix as the primary platform for real-time development communications involving the distro. From March, Matrix will replace IRC as the place where critical Ubuntu development conversations, requests, meetings, and other vital chatter must take place... Only the current #ubuntu-devel and #ubuntu-release Libera IRC channels are moving to Matrix, but other Ubuntu development-related channels can choose to move — officially, given some projects were using Matrix over IRC already.

As a result, any major requests to/of the key Ubuntu development teams with privileged access can only be actioned if requests are made on Matrix. Canonical-employed Ubuntu developers will be expected to be present on Matrix during working hours... The aim is to streamline organisation, speed up decision making, ensure key developers are reliably reachable, and avoid discussions and conversations from fragmenting across multiple platforms... It's hoped that in picking one platform as the 'chosen one' the split in where the distro's development discourse takes place can be reduced and greater transparency in how and when decisions are made restored.

IRC remains popular with many Ubuntu developers but its old-school, lo-fi nature is said to be off-putting to newer contributors. They're used to richer real-time chat platforms with more features (like discussion history, search, offline messaging, etc). It's felt this is why many newer developers employed by Canonical prefer to discuss and message through the company's internal Mattermost instance — which isn't publicly accessible. Many Ubuntu teams, flavours, and community chats already take place on Matrix...
"End-users aren't directly affected, of course," they point out. But an earlier post on the same blog notes that Matrix "is increasingly ubiquitous in open-source circles. GNOME uses it, KDE embraces it, Linux Mint migrated last year, Mozilla a few years before, and it's already widely used by Ubuntu community members and developers." IRC remains unmatched in many areas but is, rightly or wrongly, viewed as an antiquated communication platform. IRC clients aren't pretty or plentiful, the syntax is obtuse, and support for 'modern' comforts like media sending, read receipts, etc., is lacking.To newer, younger contributors IRC could feel ancient or cumbersome to learn.

Though many of IRC's real and perceived shortcomings are surmountable with workarounds, clients, bots, scripts, and so on, support for those varies between channels, clients, servers, and user configurations. Unlike IRC, which is a centralised protocol relying on individual servers, Matrix is federated. It lets users on different servers to communicate without friction. Plus, Matrix features encryption, message history, media support, and so, meeting modern expectations.

Spirit Aerosystems builds aircraft components, including fuselages and flight deck sections for Boeing, according to Wikipedia. But now Boeing is set to acquire Spirit AeroSystems.

The aviation blog called Aviation Source News says the price tag was $4.7 billion, and opines that Boeing's move signals "a renewed focus on quality and supply chain stability" as Boeing "addresses lingering concerns surrounding its 737 program." Spirit's recent struggles with quality control and production delays have had a fallout effect for Boeing... By integrating Spirit's operations, Boeing can implement more stringent oversight and ensure consistent manufacturing processes. This move is a direct response to past quality lapses that have plagued the company and damaged its reputation. Beyond quality control, the acquisition also offers Boeing greater control over its supply chain. By bringing a key supplier in-house, Boeing can streamline production, improve coordination, and reduce the risk of future disruptions...

Spirit AeroSystems also supplies parts to Airbus, Boeing's main competitor. To address this, a separate agreement is being negotiated for Airbus to acquire Spirit's Airbus-related business. This strategic move ensures that Airbus maintains control over its own supply chain and prevents Boeing from gaining undue influence over its competitor's production.
Meanwhile, the vice president leading Boeing's Starliner spacecraft unit "has left his role in the program and been replaced by the company's International Space Station program manager, John Mulholland," Reuters reports, citing a Boeing spokesperson. In its first test mission last summer flying astronauts, Starliner was forced by NASA to leave its crew aboard the ISS and return empty in September over problems with its propulsion system. A panel of senior NASA officials in August had voted to have a Crew Dragon capsule from Elon Musk's SpaceX bring them back instead, deeming Starliner too risky for the astronauts.

Paul Hill, a veteran NASA flight director and member of the agency's Aerospace Safety Advisory Panel, said during a quarterly panel meeting on Thursday that NASA and Boeing continue to investigate Starliner's propulsion system. A Boeing spokesperson said on Thursday that the company and NASA have not yet determined what Starliner's next mission will look like, such as whether it will need to repeat its crewed flight test before receiving NASA certification for routine flights.

"Sometimes, government makes a bad bet..." writes the Los Angeles Times. Opening in 2014, the Ivanpah concentrated solar plant "quickly became known as an expensive, bird-killing eyesore." Assuming that state officials sign off — which they most likely will, because the deal will lead to lower bills for PG&E customers — two of the three towers will shut down come 2026. Ivanpah's owners haven't paid off the project's $1.6-billion federal loan, and it's unclear whether they'll be able to do so. Houston-based NRG Energy, which operates Ivanpah and is a co-owner with Kelvin Energy and Google, said that federal officials took part in the negotiations to close PG&E's towers and that the closure agreement will allow the federal government "to maximize the recovery of its loans." It's possible Ivanpah's third and final tower will close, too. An Edison spokesperson told me the utility is in "ongoing discussions" with the project's owners and the federal government over ending the utility's contract.

It might be tempting to conclude government should stop placing bets and just let the market decide. But if it weren't for taxpayers dollars, large-scale solar farms, which in 2023 produced 17% of California's power, might never have matured into low-cost, reliable electricity sources capable of displacing planet-warming fossil fuels. More than a decade ago, federal loans helped finance some of the nation's first big solar-panel farms.

Not every government investment will be a winner. Renewable energy critics still raise the specter of Solyndra, a solar panel manufacturer that filed for bankruptcy in 2011 after receiving a $535-million federal loan. But on the whole, clean power investments have worked out. The U.S. Department of Energy reported that as of Dec. 31, it had disbursed $40.5 billion in loans. Of that amount, $15.2 billion had already been repaid. The federal government was on the hook for $1.03 billion in estimated losses but had reaped $5.6 billion in interest.
The article notes recent U.S. energy-related loans to a lithium mine in Nevada (close to $1 billion) and $15 billion to expand hydropower, upgrade power lines, and add batteries. Some of the loans won't get paid back "If federal officials are doing their jobs well," the article adds. "That's the risk inherent to betting on early-stage technologies." About the Ivanpah solar towers, they write "Maybe they never should have been built. They're too expensive, they don't work right, they kill too many birds... It's good that their time is coming to an end. But we should take inspiration from them, too: Don't get complacent. Keep trying new things."

PG&E says their objective at the time was partly to "support new technologies," with one senior director of commercial procurement noting "It's not clear in the early stages what technologies will work best and be most affordable for customers. Solar photovoltaic panels and battery energy storage were once unaffordable at large scale." But today they've calculated that ending their power agreements with Ivanpah would cost customers "substantially less." And once deactivated, Ivanpah's units "will be decommissioned, providing an opportunity for the site to potentially be repurposed for renewable PV energy production," NRG said in a statement.

The Las Vegas Review-Journal notes that instead the 3,500-acre, 386-megawatt concentrated thermal power plant used a much older technology, "a system of mirrors to reflect sunlight and generate thermal energy, which is then concentrated to power a steam engine." Throughout the day, 350,000 computer-controlled mirrors track the sunlight and reflect it onto boilers atop 459-foot towers to generate AC. Nowadays, photovoltaic solar has surpassed concentrated solar power and become the dominant choice for renewable, clean energy, being more cost effective and flexible... So many birds have been victims of the plant's concentrated sun rays that workers referred to them as "streamers," for the smoke plume that comes from birds that ignite in midair. When federal wildlife investigators visited the plant around 10 years ago, they reported an average of one "streamer" every two minutes.
"Meanwhile, environmentalists continue to blame the Mojave Desert plant for killing thousands of birds and tortoises," reports the Associated Press. And a Sierra Club campaign organizer also says several rare plant species were destroyed during the plant's construction. "While the Sierra Club strongly supports innovative clean energy solutions and recognizes the urgent need to transition away from fossil fuels, Ivanpah demonstrated that not all renewable technologies are created equal."

An anonymous reader quotes a report from Ars Technica: What exactly is wrong with the batteries in some of Google's Pixel 4a phones still out there? Google has not really said. Now that many Pixel 4a owners are experiencing drastically reduced battery life after an uncommon update for an end-of-life phone, they are facing a strange array of options with no path back to the phone they had.

Google's "Pixel 4a Battery Performance Program," announced in early January, told owners that an automatic update would, for some "Impacted Devices," reduce their battery's runtime and charging performance. "Impacted" customers could choose, within one year's time, between three "appeasement" options: sending in the phone for a battery replacement, getting $50 or the equivalent in their location, or receiving $100 in credit in the Google Store toward a new Pixel phone. No safety or hazard issue was mentioned in the support document.

Google did not explain why only certain devices were affected, but Hector Martin -- of Asahi Linux on Apple silicon, open source Kinect drivers, and other fame -- took apart the update's binary kernel and has some guesses. Martin points out that the updated Pixel 4a kernel has these interesting characteristics:

- It seems to have been built by a Google engineer "on their personal machine, not the proper buildsystem."
-- There is no source provided, as would normally be required of a Linux kernel build, though it may only need to be provided on request under the GNU General Public License.
- The maximum charge voltage of certain battery profiles changes from 4.44 volts to 3.95, which would mean batteries cannot charge to anywhere near their former potential.
- There are two main battery profiles, with distinct "ATL" and "LSN" markers; Martin suggests they relate to Amperex Technology Limited and Lishen, manufacturers of battery cells.
- LSN-tagged batteries assigned the "debug" profile can see capacity reduced from 3,080 milliamp hours (mAh) to 1,539 mAh. The big question is why Google pushed an automatic update to a phone from 2020. "No news or community reports have surfaced yet of Pixel 4a devices causing fires, or even simply failing to function, after four years," writes Ars' Kevin Purdy. "It's an automatic update with a strong fix, but for what?"

Google's support page only states that the update will "improve the stability of their battery's performance."
