Long-time Slashdot reader Geoffrey.landis writes: Despite its impressive output, a recent study from MIT suggests generative AI doesn't have a coherent understanding of the world. While the best-performing large language models have surprising capabilities that make it seem like the models are implicitly learning some general truths about the world, that isn't necessarily the case. The recent paper showed that Large Language Models and game-playing AI implicitly model the world, but the models are flawed and incomplete. An example study showed that a popular type of generative AI model accurately provided turn-by-turn driving directions in New York City, without having formed an accurate internal map of the city. Though the model can still navigate effectively, when the researchers closed some streets and added detours, its performance plummeted. And when they dug deeper, the researchers found that the New York maps the model implicitly generated had many nonexistent streets curving between the grid and connecting far away intersections.

Long-time Slashdot reader DesScorp writes: The Washingtonian magazine reports that yet another company is ending most remote work for its employees. The Post's previous policy from 2022 until now had been 3 days in office, 2 days remote. The employee union for the paper, the Washington Post Guild, will oppose the mandate. The union sent members a defiant email, according to the article. "Guild leadership sees this for what it is: a change that stands to further disrupt our work than to improve our productivity or collaboration." Managers will have to return beginning February 3, 2025, and all other employees will be expected in the office beginning June 2 [according to a memo from publisher Will Lewis]. "I want that great office energy for us every day," Lewis writes. "I am reliably informed that is how it used to be here before Covid, and it's important we get this back."

"Java application security would be enhanced through two proposals aimed at resisting quantum computing attacks," reports InfoWorld, "one plan involving digital signatures and the other key encapsulation." The two proposals reside in the OpenJDK JEP (JDK Enhancement Proposal) index. The Quantum-Resistant Module-Lattice-Based Digital Signature Algorithm proposal calls for enhancing the security of Java applications by providing an implementation of the quantum-resistant module-latticed-based digital signature algorithm (ML-DSA). ML-DSA would secure against future quantum computing attacks by using digital signatures to detect unauthorized modifications to data and to authenticate the identity of signatories. ML-DSA was standardized by the United States National Institute of Standards and Technology (NIST) in FIPS 204. The Quantum-Resistant Module-Lattice-Based Key Encapsulation Mechanism proposal calls for enhancing application security by providing an implementation of the quantum-resistant module-lattice-based key encapsulation mechanism (ML-KEM). KEMs are used to secure symmetric keys over insecure communication channels using public key cryptography. ML-KEM is designed to be secure against future quantum computing attacks and was standardized by NIST in FIPS 203.

Slashdot reader sciencehabit shared this report from Science magazine: Elephants love showering to cool off, and most do so by sucking water into their trunks and spitting it over their bodies. But an elderly pachyderm named Mary has perfected the technique by using a hose as a showerhead, much in the way humans do. The behavior is a remarkable example of sophisticated tool use in the animal kingdom. But the story doesn't end there. Mary's long, luxurious baths have drawn so much attention that an envious elephant at the Berlin Zoo has figured out how to shut the water off on her supersoaking rival—a type of sabotage rarely seen among animals. Both behaviors, reported today in Current Biology, further cement elephants as complex thinkers, says Lucy Bates, a behavioral ecologist at the University of Portsmouth not involved in the study. The work, she says, 'suggests problem solving or even 'insight.''

Salesforce "plans to hire more than 1,000 workers to sell its new generative AI agent product," reports Bloomberg: The hiring surge is aimed at capitalizing on "amazing momentum" for the new artificial intelligence product, Chief Executive Marc Benioff said in a message. "Agentforce became available just two weeks ago and we're already hearing incredible feedback from our customers." The top seller of customer relations management software, Salesforce pivoted its AI strategy this year to focus on agents — tools that can complete tasks such as customer support or sales development without human supervision. It launched the product, dubbed Agentforce, last month, with initial pricing of about $2 per agent conversation.

The Free Software Foundation turns forty on October 4, 2025 "and we will end our thirties on a high note!" they announced this week: We wish we were celebrating the achievement of software freedom for all computer users, but we're not there yet. Until our mission becomes reality and we can retire, instead, we are celebrating forty years of activism, and all that we have achieved. Since our founding in 1985, we laid out many stepping stones on the road to software freedom, and we're eager to continue building the road ahead. We will celebrate our fortieth in the spirit of bringing the international free software community together, discussing what we can do next to make the world freer, and celebrating how far we've come. We're aiming for a libre planet! Sounds familiar? Instead of hosting one LibrePlanet conference in 2025, we're planning a jam-packed anniversary year, filled with several new and exciting activities! We'll begin the anniversary year with an unprecedented memorabilia auction, starting as a silent auction on March 17, and culminating in a virtual live auction on March 23. By moving out of the FSF office, we got to sort through all the fun and historically important memorabilia and selected the best ones. This is your chance to get your very own personal souvenir of the FSF, from original GNU art to a famous katana and the very same VT220 that was standing on the FSF's front desk, and which people used to display ASCII art or to play free software games. Let's claim the month of May as libre planet (or libre local) month! We're inviting free software supporters like you anywhere in the world, to organize an in-person community meetup in your area to bring people together. We're setting up a small fund for these local gatherings, can send stickers, flyers, ideas and tips, and you can invite an FSF staff member to give a talk or workshop during your event and of course, we'll help promote it... Then, on the actual birthday of the FSF on October 4, 2025, there will be a big celebration in Boston, MA, and the entire free software community is invited... These are just some of the big ticket items we have worked out, but there is more! Keep an eye out on the FSF's pages, we'll be posting exact information on everything upcoming. They're looking for volunteers — and they also suggest organizing a community meetup in your area. Plus, there's also an FSF Anniversary Logo Contest. "We would like to source the fortieth anniversary logo design directly from a free software supporter. Everyone is welcome to submit a design (or even multiple designs) no matter your previous experience in design." The winning design "will be chosen by the community and ultimately immortalized in the history of the FSF," according to the announcement — displayed on the FSF homepage, printed on all celebration materials, "and possibly even stamped on some merchandise." But of course, the contest's requirements include respecting everyone's freedoms: - The logo must be produced using exclusively free software editing tools, such as GIMP, Krita, or Inkscape; - Any fonts used in the design must be under the SIL Open Font license or another free license... "The final logo will be released under CC BY, attributed to the FSF."

NASA hopes to stimulate in-space manufacturing through a multi-year "laser beam welding collaboration" with Ohio State University. The project "seeks to understand the physical processes of welding on the lunar surface," according to NASA.gov, "such as investigating the effects of laser beam welding in a combined vacuum and reduced gravity environment." The goal is to increase the capabilities of manufacturing in space to potentially assemble large structures or make repairs on the Moon, which will inform humanity's next giant leap of sending astronauts to Mars and beyond. "For a long time, we've used fasteners, rivets, or other mechanical means to keep structures that we assemble together in space," said Andrew O'Connor, a Marshall materials scientist who is helping coordinate the collaborative effort and is NASA's technical lead for the project. "But we're starting to realize that if we really want strong joints and if we want structures to stay together when assembled on the lunar surface, we may need in-space welding." The ability to weld structures in space would also eliminate the need to transport rivets and other materials, reducing payloads for space travel. That means learning how welds will perform in space. To turn the effort into reality, researchers are gathering data on welding under simulated space conditions, such as temperature and heat transfer in a vacuum; the size and shape of the molten area under a laser beam; how the weld cross-section looks after it solidifies; and how mechanical properties change for welds performed in environmental conditions mimicking the lunar surface. "Once you leave Earth, it becomes more difficult to test how the weld performs, so we are leveraging both experiments and computer modeling to predict welding in space while we're still on the ground," said O'Connor. In August 2024, a joint team from Ohio State's Welding Engineering and Multidisciplinary Capstone Programs and Marshall's Materials & Processes Laboratory performed high-powered fiber laser beam welding aboard a commercial aircraft that simulated reduced gravity. The aircraft performed parabolic flight maneuvers that began in level flight, pulled up to add 8,000 feet in altitude, and pushed over at the top of a parabolic arc, resulting in approximately 20 seconds of reduced gravity to the passengers and experiments. While floating in this weightless environment, team members performed laser welding experiments in a simulated environment similar to that of both low Earth orbit and lunar gravity. Analysis of data collected by a network of sensors during the tests will help researchers understand the effects of space environments on the welding process and welded material. They performed that laser-beam welding in a vacuum chamber during the parabolic flight (on a Boeing 727), according to the article — and successfully completed 69 out of 70 welds in microgravity and lunar gravity conditions. "The last time NASA performed welding in space was during the Skylab mission in 1973... "Practical welding and joining methods and allied processes, including additive manufacturing, will be required to develop the in-space economy."

Nathan Sobo "joined GitHub in late 2011 to build the Atom text editor," according to an online biography, "and he led the Atom team until 2018." Max Brunsfeld joined the Atom team in 2013, and "While driving Atom towards its 1.0 launch during the day, Max spent nights and weekends building Tree-sitter, a blazing-fast and expressive incremental parsing framework that currently powers all code analysis at GitHub." Last year they teamed up with Antonio Scandurra (another Atom alumnus) to launch a new startup called Zed (which in 2023 raised $10 million, according to TechCrunch). And today the open source blog It's FOSS checks in on their open-source code editor — "Zed Editor". Mainly written in Rust, it supports running in CLI, diagnosing project-wide errors, split panes, and markdown previews: By default, any added content is treated as plain text. I used the language switcher to change it to Rust so that I would get proper syntax highlighting, indentation, error detection, and other useful language-specific functions. The switch highlighted all the Rust elements correctly, and I then focused on Zed Editor's user interface. The overall feel of the editor was minimal, with all the important options being laid out nicely. [Its status bar] had some interesting panels. The first one I checked was the Terminal Panel, which, as the name suggests, lets you run commands, scripts, and facilitates interaction with system files or processes directly from within the editor. I then moved to the Assistant Panel, which is home to various large language models that can be integrated into Zed Editor. There are options like Anthropic, GitHub Copilot Chat, Ollama, OpenAI, and Google AI... The Zed Editor team has also recently introduced Zed AI in collaboration with Anthropic for assisting with coding, allowing for code generation, advanced context-powered interactions, and more... The real-time collaboration features on Zed Editor are quite appealing too. To check them out, I had to log in with my GitHub account. After logging in, the Collab Panel opened up, and I could see many channels from the official Zed community. I could chat with others, add collaborators to existing projects, join a call with the option to share my screen and track other collaborators' cursors, add new contacts, and carry out many other collaborative tasks. One can also use extensions and themes to extend what Zed Editor can do. There are some nice pre-installed themes as well.

"The Rust trademark policy has been updated and a new draft is available to view," announced the Rust Foundation this week. The last proposed trademark policy (in April of 2023) was criticized by open source advocate Bruce Perens in The Register as "far awry of fair use which is legally permitted." The Rust Foundation says this new version has "incorporated a number of suggestions from the Rust community," in a blog post that summarizes the feedback and enumerates specific ways it's been addressed: 1. We primarily plan to lean on community reports for enforcement and have no intention of spending our limited resources policing the work of small creators. 2. We have removed the non-legal language summary and instead have clarified wording throughout as best we can while keeping the policy valid. 3. The Rust trademark does not cover use of the word "Rust" in general and instead pertains to its use in relevant technical settings. 4. We have updated the logo usage policy. Color modifications are allowed. 5. The non-endorsement rule is about managing perception of official affiliation with the Foundation and Rust Project, and is thus subjective. 6. We removed restrictions on the use of "Rust" and "Cargo" in package names. The crates prefixes "rust-" and "cargo-" are no longer reserved to the Rust Project. 7. We will usually allow the community to use the marks on limited merchandise (more details in the updated draft).... [T]he central purpose of these updates is to empower all Rustaceans to engage with the Rust language ecosystem more confidently. As a final step in this process, we invite you to review the updated policy and share any blocking concerns you might have... Thank you to everyone who weighed in with helpful suggestions on the initial trademark policy draft we shared. The level of engagement and passion within the Rust community is inspiring to all of us at the Rust Foundation. The tech news site Heise Online writes "It is noticeable that the language is much clearer and dispenses with a lot of legal jargon," in a piece which argues the new draft "should calm the waves and create clarity." The new draft is not only formulated more simply, but is also significantly shorter. Some restrictions have been softened in the new rules or have disappeared completely... Meanwhile, the Foundation has also adapted its logo so that it is clear which logo stands for the programming language and which for the Foundation. The use of the name Rust is explicitly permitted to identify projects that are either written in the programming language or are compatible with it... Before the new trademark rules come into force, the Rust Foundation is collecting feedback on the current draft. The web form is open until November 20, 2024.

Sodium-ion batteries are cheaper than lithium-ion batteries — and they're also more environmentally friendly. And "In the past few years, sodium-ion battery production has increased in the United States," reports the Washington Post, with a new factory planned to manufacture them "in the same way as lithium-ion batteries, just with different ingredients. Instead of using expensive materials like lithium, nickel and cobalt, these will be made of sodium, iron and manganese..." Last month, sodium-ion battery manufacturer Natron Energy announced it would open a "gigafactory" in North Carolina that would produce 24 gigawatt hours of batteries annually, enough energy to charge 24,000 electric vehicles. But sodium-ion batteries are still early in their development compared with lithium-ion, and they have yet to hit the market on a massive scale. "It's unlikely sodium-ion could displace lithium-ion anytime soon," said Keith Beers, polymer science and materials chemistry principal engineer at technical consultancy firm Exponent... The biggest limitation of sodium-ion batteries is their weight. Sodium weighs nearly three times as much as lithium, and it cannot store the same amount of energy. As a result, sodium-ion batteries tend to be larger. Jens Peters, an economics professor at the University of Alcalá in Madrid, said the energy density could be improved over time in sodium-ion batteries. But, he added, "what we found out so far in our assessments is that it is not a game changer." Sodium-ion batteries are touted to be the environmentally friendly alternative to their lithium-ion counterparts, thanks to their raw materials. Sodium, iron and manganese are all abundant elements on the planet, so they require less energy to extract and cost less... Sodium-ion batteries also last longer than lithium-ion ones because they can withstand more charge cycles, said Wendell Brooks, co-CEO of Natron Energy. "Our product can have millions of cycles," said Brooks, "where lithium-ion would have three to five thousand cycles and wear out a lot faster...." Sodium-ion batteries aren't the best fit for smartphones or electric vehicles, which need to store lots of energy. However, one advantage is their low cost. And they could be a good candidate in situations where the size of the battery isn't a concern, like energy storage. "When something is built out to support grid or backup storage, it doesn't need to be very dense. It's staying put," Beers said. Natron will invest nearly $1.4 billion in the factory "to meet the rapidly expanding demand for critical power, industrial and grid energy storage solutions," according to their announcement. "Natron's high-performance sodium-ion batteries outperform lithium-ion batteries in power density and recharging speed, do not require lithium, cobalt, copper, or nickel, and are non-flammable... Natron's batteries are the only UL-listed sodium-ion batteries on the market today, and will be delivered to a wide range of customer end markets in the industrial power space, including data centers, mobility, EV fast charging, microgrids, and telecom, among others."

On Tuesday Massachusetts voted to become the first state to allow gig-working drivers to join labor unions, reports WBUR: Since these gig workers are classified as independent contractors, federal law allowing employees the right to unionize does not apply to them. With the passage of this ballot initiative, Massachusetts is the first state to give ride-hailing drivers the ability to collectively bargain over working conditions. Supporters have said the ballot measure "could provide a model for other states to let Uber and Lyft drivers unionize," reports Reuters, "and inspire efforts to organize them around the United States." Roxana Rivera, assistant to the president of 32BJ SEIU, an affiliate of the Service Employees International Union, that had spearheaded a campaign to pass the proposal, said its approval shows that Massachusetts voters want drivers to have a meaningful check against the growing power of app-based companies... The Massachusetts vote was the latest front in a years-long battle in the United States over whether ride-share drivers should be considered to be independent contractors or employees entitled to benefits and wage protections. Studies have shown that using contractors can cost companies as much as 30% less than employees. Drivers for Uber and Lyft, including approximately 70,000 in Massachusetts, do not have the right to organize under the National Labor Relations Act... Under the Massachusetts measure, drivers can form a union after collecting signatures from at least 25% of active drivers in Massachusetts, and companies can form associations to allow them to jointly negotiate with the union during state-supervised talks. But the Boston Globe points out that the measure " divided labor advocates in Massachusetts, some of whom worry it would in fact be a step backward in the lengthy fight to boost the rights of gig workers." Those concerns led the state's largest labor organization, the AFL-CIO, to remain neutral. But two unions backing the effort, the SEIU 32BJ and the International Association of Machinists, say allowing drivers to unionize, even if not as full employees, will help provide urgently needed worker protections and better pay and safety standards.

Friday "would have been his 38th birthday," writes the EFF, remembering Aaron Swartz as "a digital rights champion who believed deeply in keeping the internet open..." And they add that today the official web site for Aaron Swartz Day honored his memory with a special podcast "featuring those carrying on the work around issues close to his heart," including an appearance by Brewster Kahle, founder of the Internet Archive. The first speaker is Ryan Shapiro, FOIA expert and co-founder of the national security transparency non-profit Property of the People. The Aaron Swartz Day site calls him "the researcher who discovered why the FBI had such an interest in Aaron in the years right before the JSTOR fiasco." (That web page calls it an "Al Qaeda phishing expedition that left Aaron with an 'International Terrorism Investigation' code in his FBI database file forever," as reported by Gizmodo.) Other speakers on the podcast include: Nathan Dyer of SecureDrop, Newsroom Support Engineer for the Freedom of the Press Foundation with an update on SecureDrop Tracey Jaquith, Founding Coder and TV Architect at the Internet Archive, discussing "Microservices, Monoliths, and Operational Security — The Internet Archive in 2024." Tracy Rosenberg, co-founder of the Aaron Swartz Day Police Surveillance Project and Oakland Privacy, with "an update on the latest crop of surveillance battles." Ryan Sternlicht, VR developer, educator, researcher, advisor, and maker, on "The Next Layer of Reality: Social Identity and the New Creator Economy." Grant Smith Ellis, Chairperson of the Board, MassCann and Legal Intern at the Parabola Center, on "Jury Trials in the Age of Social Media." Michael "Mek" Karpeles, Open Library, Internet Archive, on "When it Rains at the Archive, Build an Ark — Book bans, Lawsuits, & Breaches." The site also seeks to showcase SecureDrop and Open Library, projects started by Aaron before his death, as well as new projects "directly inspired by Aaron and his work."

This week Discover magazine looks at evidence — both old and new — for a ninth planet in our solar system: "Orbits of the most distant small bodies — comets or asteroids — seem to be clustered on one half or one side of the solar system," says Amir Siraj [an astrophysicist with Princeton University]. "That's very weird and something that can't be explained by our current understanding of the solar system." A 2014 study in Nature first noted these orbits. A 2021 study in The Astronomical Journal examined the clustering in the orbit and concluded that "Planet Nine" was likely closer and brighter than expected. Astrophysicists don't agree whether the clustering in the orbit is a real effect. Some have argued it is biased because the view that scientists currently have is limited, Siraj says. "This debate for the last decade has a lot of scientists confused, including myself. I decided to look at the problem from scratch," he says. In a 2024 paper, Siraj and his co-authors ran simulations of the solar system, including an extra planet beyond Neptune. "We did it 300 times, about 2.5 times more than what was done previously," Siraj says. "In each simulation, you try different parameters for the extra planet. A different mass, a different tilt, a different shape of the orbit. You run these for millions of years, and then you compare the distribution to what we see in our solar system...." They found that the perimeters for this possible planet were different than what has been previously discussed in the scientific literature, and they supported the possibility of an unseen planet beyond Neptune. Scientists hope a new telescope will have the potential to see deeper into the solar system. In 2025, the Vera C. Rubin Observatory on Cerro Pachón — a mountain in Chile, is expected to go online. The observatory boasts that in the time it takes a person to open up their phone and pose for a selfie, their new telescope will be able to snap an image of 100,000 galaxies, many of which have never been seen by scientists. The telescope will have the largest digital camera ever built, the LSST. Siraj says he expects it will take "the deepest, all-sky survey that humanity has ever conducted." So, what might the Rubin Observatory find past Neptune? Based on the current literature, Siraj sees a few possibilities. One is that the Rubin Observatory, with its increased capabilities, might be able to see a planet beyond Neptune... "Next year is going to be an enormous year for solar system science," he says. NASA points out that the Hawaii-based Keck and Subaru telescopes are also searching for Planet X, while "a NASA-funded citizen science project called Backyard Worlds: Planet 9, encourages the public to help search using images captured by NASA's Wide-field Infrared Survey Explorer (WISE) mission. And starting next year the Rubin observatory will also "search for more Kuiper Belt objects. If the orbits of these objects are systematically aligned with each other, it may give more evidence for the existence of Planet X (Planet Nine), or at least help astronomers know where to search for it. "Another possibility is that Planet X (Planet Nine) does not exist at all. Some researchers suggest the unusual orbit of those Kuiper Belt objects can be explained by their random distribution."

"The majority of strokes could be prevented," reports the Associated Press, according to the first new guidelines in 10 years from the American Stroke Association, which are "aimed at helping people and their doctors do just that." Stroke was the fourth leading cause of death in the U.S. in 2023, according to the Centers for Disease Control and Prevention, and more than half a million Americans have a stroke every year. But up to 80% of strokes may be preventable with better nutrition, exercise and identification of risk factors... The good news is that the best way to reduce your risk for stroke is also the best way to reduce your risk for a whole host of health problems — eat a healthy diet, move your body and don't smoke... Eating healthy can help control several factors that increase your risk for stroke, including high cholesterol, high blood sugar, and obesity, according to the heart association. The group recommends foods in the so-called Mediterranean diet such as fruits, vegetables, whole grains and olive oil, which can help keep cholesterol levels down. It suggests limiting red meat and other sources of saturated fat. Instead, get your protein from beans, nuts, poultry, fish and seafood. Limit highly processed foods and foods and drinks with a lot of added sugar. This can also reduce your calorie intake, which helps keep weight in check. Getting up and walking around for at least 10 minutes a day can "drastically" reduce your risk, said Dr. Cheryl Bushnell, a neurologist at Wake Forest University School of Medicine who was part of the group that came up with the new guidelines. Among the many benefits: Regular exercise can help reduce blood pressure, a major risk factor for stroke. Of course, more is better: The heart association recommends at least 150 minutes of moderate aerobic or 75 minutes of vigorous activity — or some combination — per week. How you do it doesn't matter so much, experts said: Go to the gym, take a walk or run in your neighborhood or use treadmills or stepper machines at home. Diet and exercise can help control weight, another important risk factor for strokes. But in addition, the guidelines now recommend that doctors consider new weight-loss drugs like Ozempic, Wegovy, Mounjaro and Zepbound for people with obesity or diabetes. (Though "people still need to eat well and get exercise, cautions Dr. Fadi Nahab, a stroke expert at Emory University Hospital.")

Tuesday at California's Vandenberg Space Force base, the U.S. launched a Minuteman III missile, "in an important test of the weapon's ability to strike its targets with multiple warheads," according to Air and Space Forces magazine: The Minuteman III missiles that form a critical leg of the U.S. nuclear triad each carry one nuclear-armed reentry vehicle. But the missile that was tested carried three test warheads... The intercontinental ballastic missile (ICBM) test was controlled by an airborne command post in a test of the U.S. ability to launch its nuclear deterrent from a survivable platform.... Gen. Thomas A. Bussiere, the commander of Air Force Global Strike Command, said in a release: "An airborne launch validates the survivability of our ICBMs, which serve as the strategic backstop of our nation's defense and defense of allies and partners...." The three test reentry vehicles — one high-fidelity Joint Test Assembly, which carries non-nuclear explosives, and two telemetry Joint Test Assembly objects — struck the Reagan Test Site near the Kwajalein Atoll in the Marshall Islands roughly 30 minutes later after launch, a flight of about 4,200 miles. "They make up essentially a mock warhead," Col. Dustin Harmon, the commander of the 377th Test and Evaluation Group, the nation's operational ICBM test unit, said in an interview with Air & Space Forces Magazine. "There's two different types. One is telemetered, so it's got a radio transmitter in it, it's got antennas, gyroscopes, accelerometers — all the things that can sense motion and movement. And we fly those or we can put one in there that's called a high-fidelity. That is assembled much like an actual weapon would be, except we use surrogate materials, and so we want it to fly similarly to an actual weapon. ... It has the explosives in it that a normal warhead would to drive a detonation, but there's nothing to drive...." The U.S. government formally notified Russia in advance of the launch in accordance with a 1988 bilateral agreement. More than 145 countries were also provided with advance notice of the launch under the Hague Code of Conduct — an international understanding on launch notifications. The U.S. also provided advance notice to China, a DOD spokesperson told Air & Space Forces Magazine. China notified the U.S. of an ICBM launch over the Pacific Ocean in September. There is no formal agreement between Washington and Beijing that requires such notifications, but each side provided them to avoid miscalculations. Test launches happen three times a year, according to the article, yielding "several gigabytes of data" about reentry vehicles, subsystems, and payloads. "There are 400 Minuteman III missiles currently in service across Colorado, Montana, Nebraska, North Dakota, and Wyoming." Thanks to long-time Slashdot reader SonicSpike for sharing the article.

Back in 1976, Mattel Electronics Auto Race became the very first handheld game to use only solid-state electronics, according to Wikipedia. (Its only mechanical elements were its on/off switch and hand-operated controls...) Nearly half a century goes by — until the ancient and broken gizmo reaches long-time Slashdot reader Shayde, who "dove into disassembling the unit and figuring out the problem." Ironically, at one point his voltimeter stopped working, because...its batteries were dead. But a tri-wing screwdriver reveals the game's beautiful 1976 circuitboard — before the video fast forwards through "an almost comical attempt by me, a systems software engineer, to sauter the connections back onto this 48-year-old connector." (Instead he ends up replacing the machine's 9-volt battery connector...) On his Patreon page, he writes that filming the video "took a stupidly long time to put together." But their Slashdot submission acknowledges that in the end, "Taking it apart and debugging it was fun. (Slight spoiler: I figured out what was wrong, was an easy fix), and the game plays great now!" Any Slashdot readers have memories of playing Mattel Electronics Auto Race? My one experience felt like that time that a gaming magazine had nine children (ages 9 to 12) try to play old 1970s-era videogames like Pong. ("Wow. The score is tied. It's so exhilarating..." "My line is so beating the heck out of your stupid line...")

After missing a chance to capitalize on the AI boom, "Samsung's profit has plunged," reports CNBC, and "around $126 billion has been wiped off its market value, according to data from S&P Capital IQ." It's gotten so bad that "an executive issued a rare public apology about the company's recent financial performance." [A]s AI applications such as OpenAI's ChatGPT rose in popularity, the underlying infrastructure required to train the huge models they rely on became a bigger focus. Nvidia has emerged as the top player in this space with its graphics processing units (GPUs) that have become the gold standard used by tech giants for AI training. A crucial part of that semiconductor architecture is high-bandwidth memory, or HBM. This next generation of memory involves stacking multiple dynamic random access memory (DRAM) chips, but it had a small market before the AI boom. That's where Samsung got caught out and failed to invest... SK Hynix saw this opportunity. The company aggressively launched HBM chips which were approved for use in Nvidia architecture and, in the process, the South Korean firm established a close relationship with the U.S. giant. Nvidia's CEO even asked the company to speed up supply of its next generation chip, underscoring the importance of HBM to its products. SK Hynix posted record quarterly operating profit in the September quarter... Analysts said that Samsung is lagging behind competitors for a number of reasons, including underinvestment in HBM and the fact that it is not a first-mover. "It is fair to say that Samsung has not been able to close the gap with SK Hynix on the HBM development roadmap," said Kazunori Ito [director of equity research at Morningstar]. Samsung's ability to make a comeback in the short term appears to be closely linked to Nvidia. A company must pass a strict qualification process before Nvidia approves it as a HBM supplier — and Samsung has not yet completed this verification. But a green light from Nvidia could open the door for Samsung to return to growth and compete more effectively with SK Hynix, according to analysts.

An anonymous reader shared this report from Phoronix: Intel's Linux kernel test robot has reported a 3888.9% performance improvement in the mainline Linux kernel as of this past week... Intel thankfully has the resources to maintain this automated service for per-kernel commit/patch testing and has been maintaining their public kernel test robot for years now to help catch performance changes both positive and negative to the Linux kernel code. The commit in question causing this massive uplift to performance is mm, mmap: limit THP alignment of anonymous mappings to PMD-aligned sizes. The patch message confirms it will fix some prior performance regressions and deliver some major uplift in specialized cases... That mmap patch merged last week affects just one line of code. This week the Register also reported that Linus Torvalds revised a previously-submitted security tweak that addressed Spectre and Meltdown security holes, writing in his commit message that "The kernel test robot reports a 2.6 percent improvement in the per_thread_ops benchmark."

Though it breaks down faster than CO2, methane is a greenhouse gas over 80 times as potent as carbon dioxide, reports the Washington Post. It suddenly started increasing in the atmosphere in 2007 — and then in 2020, its growth rate doubled. While scientists have suspected it was natural gas, some researchers have a new theory... "The changes that we saw in the last couple of years — and even since 2007 — are microbial," said Sylvia Michel, lead author of the paper published last month in the Proceedings of the National Academy of Sciences. "Wetlands, if they are getting warmer and wetter, maybe they're producing more methane than they used to...." Michel and her co-authors analyzed samples of methane, or CH4, from 22 sites around the globe at a Colorado laboratory. Then they measured the "heaviness" of that methane — specifically, how many of the molecules had a heavier isotope of carbon in them, known as C13. Different sources of methane give off different carbon signatures. Methane produced by microbes — mostly single-celled organisms known as archaea, which live in cow stomachs, wetlands and agricultural fields — tends to be "lighter," or have fewer C13 atoms. Methane from fossil fuels, on the other hand, is heavier, with more C13 atoms. As the amount of methane has risen in the atmosphere over the past 15 years, it's also gotten lighter and lighter. The scientists used a model to analyze those changes and found that only large increases in microbial emissions could explain both the rising methane and its changing weight.... Researchers say it doesn't mean that the world can just keep burning natural gas. If wetlands are releasing methane faster than ever, they argue, there should be an even greater push to curb methane from the sources humans can control, such as cows, agriculture and fossil fuels. The article includes this quote from Stanford University professor Rob Jackson (who works on the Global Methane Budget, a project tracking the world's methane sources). "You can turn a wrench in an oil and gas field to quench methane emissions," Jackson said. "There's no wrench for the Congo or the Amazon." Another recent study found that two-thirds of current methane emissions are caused by humans — from fossil fuels, rice cultivation, reservoirs and other sources. "Methane forms biologically in warm, wet, low-oxygen environments," Jackson said. "The wetlands of a rice paddy and the gut of the cow are all similar." But evidence is also emerging that natural wetlands may be responding to warming temperatures by pumping out more methane. Satellite data from recent years has shown global methane hot spots in the tropical wetlands of the Amazon and the Congo. "Wetlands will emit more methane as temperatures warm," Jackson said. "This may be the start of a reinforcing feedback, that higher temperatures release more methane from natural ecosystems...." Over 100 countries have pledged to reduce their methane emissions by 30 percent by 2030, compared with 2020 levels — but so far, that pledge has yet to see results. Instead, satellite measurements show concentrations are rising at a rate that is in line with the worst-case climate scenarios.
