  • LibreOffice Explains 'Real Costs' of Upgrading to Microsoft's Windows 11, Urges Taking Control with Linux
    2025-06-16T07:44:00+00:00
    KDE isn't the only organization reaching out to " as Microsoft prepares to end support for Windows 10. "Now, The Document Foundation, maker of LibreOffice, has also joined in to support the Endof10 initiative," reports the tech blog Neowin: The foundation writes: "You don't have to follow Microsoft's upgrade path. There is a better option that puts control back in the hands of users, institutions, and public bodies: Linux and LibreOffice. Together, these two programmes offer a powerful, privacy-friendly and future-proof alternative to the Windows + Microsoft 365 ecosystem." It further adds the "real costs" of upgrading to Windows 11 as it writes: "The move to Windows 11 isn't just about security updates. It increases dependence on Microsoft through aggressive cloud integration, forcing users to adopt Microsoft accounts and services. It also leads to higher costs due to subscription and licensing models, and reduces control over how your computer works and how your data is managed. Furthermore, new hardware requirements will render millions of perfectly good PCs obsolete.... The end of Windows 10 does not mark the end of choice, but the beginning of a new era. If you are tired of mandatory updates, invasive changes, and being bound by the commercial choices of a single supplier, it is time for a change. Linux and LibreOffice are ready — 2025 is the right year to choose digital freedom!" The first words on LibreOffice's announcement? "The countdown has begun...."

  • Fake Bands and Artificial Songs are Taking Over YouTube and Spotify
    2025-06-16T04:54:00+00:00
    Spain's newspaper El Pais found an entire fake album on YouTube titled Rumba Congo (1973). And they cite a study from France's International Confederation of Societies of Authors and Composers that estimated revenue from AI-generated music will rise to $4 billion in 2028, generating 20% of all streaming platforms' revenue: One of the major problems with this trend is the lack of transparency. María Teresa Llano, an associate professor at the University of Sussex who studies the intersection of creativity, art and AI, emphasizes this aspect: "There's no way for people to know if something is AI or not...." On Spotify Community — a forum for the service's users — a petition is circulating that calls for clear labeling of AI-generated music, as well as an option for users to block these types of songs from appearing on their feeds. In some of these forums, the rejection of AI-generated music is palpable. Llano mentions the feelings of deception or betrayal that listeners may experience, but asserts that this is a personal matter. There will be those who feel this way, as well as those who admire what the technology is capable of... One of the keys to tackling the problem is to include a warning on AI-generated songs. YouTube states that content creators must "disclose to viewers when realistic content [...] is made with altered or synthetic media, including generative AI." Users will see this if they glance at the description. But this is only when using the app, because on a computer, they will have to scroll down to the very end of the description to get the warning.... The professor from the University of Sussex explains one of the intangibles that justifies the labeling of content: "In the arts, we can establish a connection with the artist; we can learn about their life and what influenced them to better understand their career. With artificial intelligence, that connection no longer exists." YouTube says they may label AI-generated content if they become aware of it, and may also remove it altogether, according to the article. But Spotify "hasn't shared any policy for labeling AI-powered content..." In an interview with Gustav Söderström, Spotify's co-president and chief product & technology officer, he emphasized that AI "increases people's creativity" because more people can be creative, thanks to the fact that "you don't need to have fine motor skills on the piano." He also made a distinction between music generated entirely with AI and music in which the technology is only partially used. But the only limit he mentioned for moderating artificial music was copyright infringement... something that has been a red line for any streaming service for many years now. And such a violation is very difficult to legally prove when artificial intelligence is involved.

  • Amazon's Return-to-Office Mandate Sparks Complaints from Disabled Employees
    2025-06-16T01:34:00+00:00
    An anonymous reader shared this report from Bloomberg: Amazon's hard-line stance on getting disabled employees to return to the office has sparked a backlash, with workers alleging the company is violating the Americans with Disabilities Act as well as their rights to collectively bargain. At least two Amazon employees have filed complaints with the Equal Employment Opportunity Commission (EEOC) and the National Labor Relations Board, federal agencies that regulate working conditions. One of the workers said they provided the EEOC with a list of 18 "similarly situated" employees to emphasize that their experience isn't isolated and to help federal regulators with a possible investigation. Disabled workers frustrated with how Amazon is handling their requests for accommodations — including exemptions to a mandate that they report to the office five days a week — are also venting their displeasure on internal chat rooms and have encouraged colleagues to answer surveys about the policies. Amazon has been deleting such posts and warning that they violate rules governing internal communications. One employee said they were terminated and another said they were told to find a different position after advocating for disabled workers on employee message boards. Both filed complaints with the EEOC and NLRB. Amazon has told employees with disabilities they must now submit to a "multilevel leader review," Bloomberg reported in October, "and could be required to return to the office for monthlong trials to determine if accommodations meet their needs." (They received calls from "accommodation consultants" who also reviewed medical documentation, after which "another Amazon manager must sign off. If they don't, the request goes to a third manager...") Bloomberg's new article remembers how several employees told them in November. "that they believed the system was designed to deny work-from-home accommodations and prompt employees with disabilities to quit, which some have done. Amazon denied the system was designed to encourage people to resign." Since then, workers have mobilized against the policy. One employee repeatedly posted an online survey seeking colleagues' reactions, defying the company's demands to stop. The survey ultimately generated feedback from more than 200 workers even though Amazon kept deleting it, and the results reflected strong opposition to Amazon's treatment of disabled workers. More than 71% of disabled Amazon employees surveyed said the company had denied or failed to meet most of their accommodation requests, while half indicated they faced "hostile" work environments after disclosing their disabilities and requesting accommodations. One respondent said they sought permission to work from home after suffering multiple strokes that prevented them from driving. Amazon suggested moving closer to the office and taking mass transit, the person said in the survey. Another respondent said they couldn't drive for longer than 15-minute intervals due to chronic pain. Amazon's recommendation was to pull over and stretch during their commute, which the employee said was unsafe since they drive on a busy freeway... Amazon didn't dispute the accounts and said it considered a range of solutions to disability accommodations, including changes to an employee's commute. Amazon is also "using AI to parse accommodation requests, read doctors' notes and make recommendations based on keywords," according to the article — another policy that's also generated internal opposition (and formed a "key element" of the complaint to the Equal Employment Opportunity Commission). "The dispute could affect thousands of Amazon workers. An internal Slack channel for employees with disabilities has 13,000 members, one of the people said..."

  • Mitsubishi Launches EV Battery Swap Network in Tokyo - for Both Cars and Trucks
    2025-06-15T23:38:00+00:00
    In Tokyo Mitsubishi is deploying "an innovative new battery swap network for electric cars" in a multi-year test program reports the EV news site Electrek. But it's not just for electric cars. Along with the 14 modular battery swapping stations, Mitsubishi is also deploying "more than 150 battery-swappable commercial electric vehicles" from truck maker Fuso: A truck like the Mitsubishi eCanter typically requires a full night of AC charging to top off its batteries, and at least an hour or two on DC charging in Japan, according to Fuso. This joint pilot by Mitsubishi, Mitsubishi Fuso Trucks, and [EV battery swap specialist] Ample aims to circumvent this issue of forced downtime with its swappable batteries, supporting vehicle uptime by delivering a full charge within minutes. The move is meant to encourage the transport industry's EV shift while creating a depository of stored energy that can be deployed to the grid in the event of a natural disaster — something Mitsubishi in Japan has been working on for years. The article's author also adds their own opinion about battery-swapping technology. "When you see how simple it is to add hundreds of miles of driving in just 100 seconds — quicker, in many cases, than pumping a tank of liquid fuel into an ICE-powered car — you might come around, yourself."

  • Meta's Llama 3.1 Can Recall 42% of the First Harry Potter Book
    2025-06-15T22:32:00+00:00
    Timothy B. Lee has written for the Washington Post, Vox.com, and Ars Technica — and now writes a Substack blog called "Understanding AI." This week he visits recent research by computer scientists and legal scholars from Stanford, Cornell, and West Virginia University that found that Llama 3.1 70BÂ(released in July 2024) has memorized 42% of the first Harry Potter book well enough to reproduce 50-token excerpts at least half the time... The paper was published last month by a team of computer scientists and legal scholars from Stanford, Cornell, and West Virginia University. They studied whether five popular open-weight models — three from Meta and one each from Microsoft and EleutherAI — were able to reproduce text from Books3, a collection of books that is widely used to train LLMs. Many of the books are still under copyright... Llama 3.1 70B — a mid-sized model Meta released in July 2024 — is far more likely to reproduce Harry Potter text than any of the other four models.... Interestingly, Llama 1 65B, a similar-sized model released in February 2023, had memorized only 4.4 percent of Harry Potter and the Sorcerer's Stone. This suggests that despite the potential legal liability, Meta did not do much to prevent memorization as it trained Llama 3. At least for this book, the problem got much worse between Llama 1 and Llama 3. Harry Potter and the Sorcerer's Stone was one of dozens of books tested by the researchers. They found that Llama 3.1 70B was far more likely to reproduce popular books — such as The Hobbit and George Orwell's 1984 — than obscure ones. And for most books, Llama 3.1 70B memorized more than any of the other models... For AI industry critics, the big takeaway is that — at least for some models and some books — memorization is not a fringe phenomenon. On the other hand, the study only found significant memorization of a few popular books. For example, the researchers found that Llama 3.1 70B only memorized 0.13 percent of Sandman Slim, a 2009 novel by author Richard Kadrey. That's a tiny fraction of the 42 percent figure for Harry Potter... To certify a class of plaintiffs, a court must find that the plaintiffs are in largely similar legal and factual situations. Divergent results like these could cast doubt on whether it makes sense to lump J.K. Rowling, Richard Kadrey, and thousands of other authors together in a single mass lawsuit. And that could work in Meta's favor, since most authors lack the resources to file individual lawsuits. Why is it happening? "Maybe Meta had trouble finding 15 trillion distinct tokens, so it trained on the Books3 dataset multiple times. Or maybe Meta added third-party sources — such as online Harry Potter fan forums, consumer book reviews, or student book reports — that included quotes from Harry Potter and other popular books..." "Or there could be another explanation entirely. Maybe Meta made subtle changes in its training recipe that accidentally worsened the memorization problem."

  • Apple Migrates Its Password Monitoring Service to Swift from Java, Gains 40% Performance Uplift
    2025-06-15T21:29:00+00:00
    Meta and AWS have used Rust, and Netflix uses Go,reports the programming news site InfoQ. But using another language, Apple recently "migrated its global Password Monitoring service from Java to Swift, achieving a 40% increase in throughput, and significantly reducing memory usage." This freed up nearly 50% of their previously allocated Kubernetes capacity, according to the article, and even "improved startup time, and simplified concurrency." In a recent post, Apple engineers detailed how the rewrite helped the service scale to billions of requests per day while improving responsiveness and maintainability... "Swift allowed us to write smaller, less verbose, and more expressive codebases (close to 85% reduction in lines of code) that are highly readable while prioritizing safety and efficiency." Apple's Password Monitoring service, part of the broader Password app's ecosystem, is responsible for securely checking whether a user's saved credentials have appeared in known data breaches, without revealing any private information to Apple. It handles billions of requests daily, performing cryptographic comparisons using privacy-preserving protocols. This workload demands high computational throughput, tight latency bounds, and elastic scaling across regions... Apple's previous Java implementation struggled to meet the service's growing performance and scalability needs. Garbage collection caused unpredictable pause times under load, degrading latency consistency. Startup overhead — from JVM initialization, class loading, and just-in-time compilation, slowed the system's ability to scale in real time. Additionally, the service's memory footprint, often reaching tens of gigabytes per instance, reduced infrastructure efficiency and raised operational costs. Originally developed as a client-side language for Apple platforms, Swift has since expanded into server-side use cases.... Swift's deterministic memory management, based on reference counting rather than garbage collection (GC), eliminated latency spikes caused by GC pauses. This consistency proved critical for a low-latency system at scale. After tuning, Apple reported sub-millisecond 99.9th percentile latencies and a dramatic drop in memory usage: Swift instances consumed hundreds of megabytes, compared to tens of gigabytes with Java. "While this isn't a sign that Java and similar languages are in decline," concludes InfoQ's article, "there is growing evidence that at the uppermost end of performance requirements, some are finding that general-purpose runtimes no longer suffice."

  • Could This City Be the Model for How to Tackle the Both the Climate and Housing Crisis?
    2025-06-15T20:10:00+00:00
    NPR looks at the "high-quality, climate-friendly apartments" in Vienna, asking if it's a model for addressing both climate change and the housing crisis. About half the city's 2 million people live in the widespread (and government-supported) apartments, with solar panels on top and very thick, insulated walls that reduce the need for heating and cooling. (One resident tells NPR they don't even need an air conditioner because "It's not cold in winter times. It's not hot in summer times.") Vienna council member Nina Abrahamczik, who heads the climate and environment committee, says as the city transitions all of its buildings off planet-heating fossil fuels, they're starting with the roughly 420,000 housing units they already own or subsidize.... As Vienna makes an aggressive push to completely move away from climate-polluting natural gas by 2040, it's starting with much of this social housing, says Jürgen Czernohorszky, executive city councilor responsible for climate and environment. City-owned buildings are now switching from gas to massive electric heat pumps, and to geothermal, which involves probing into the ground to heat homes. Another massive geothermal project that drills even deeper into the earth to heat homes is also underway. The city is also powering housing with solar energy. As of a year and a half ago, Vienna mandates all new buildings and building extensions to have rooftop solar. And Vienna's older apartment buildings are getting climate retrofits, says Veronika Iwanowski, spokesperson for Vienna's municipal housing company, Wiener Wohnen. That includes new insulation, doors and windows to prevent the city's wind from getting in the cracks. The increase in energy efficiency and switching from gas to renewables doesn't just have climate benefits from cutting fossil fuel use. It also means housing residents are paying less on electric bills... With city-subsidized housing, housing developers can compete to get land and low-interest loans from the city. Officials say those competitions are a critical lever for climate action. "As we can control the contents of the competitions, we try to make them fit to the main goals of the city," says Kurt Hofstetter, city planner for Vienna, "which is of course also ecological...." Now the housing judges give out points for things like increased energy efficiency, green roofs and sustainable building materials... Now the climate innovations in subsidized housing are inspiring the private market as well, Hofstetter says... The article notes that most of the city's funding is provided in the form of low-interest loans, according to a researcher at the Austrian Federation of Limited-Profit Housing Associations. (And the average social housing rents are about $700 for a large one-bedroom apartment, says Gerald Kössl, researcher at the Austrian Federation of Limited-Profit Housing Associations.)

  • Facial Recognition Error Sees Woman Wrongly Accused of Theft
    2025-06-15T18:20:00+00:00
    A chain of stores called Home Bargains installed facial recognition software to spot returning shoplifters. Unfortunately, "Facewatch" made a mistake. "We acknowledge and understand how distressing this experience must have been," an anonymous Facewatch spokesperson tells the BBC, adding that the store using their technology "has since undertaken additional staff training." A woman was accused by a store manager of stealing about £10 (about $13) worth of items ("Everyone was looking at me"). And then it happened again at another store when she was shopping with her 81-year-old mother on June 4th: "As soon as I stepped my foot over the threshold of the door, they were radioing each other and they all surrounded me and were like 'you need to leave the store'," she said. "My heart sunk and I was anxious and bothered for my mum as well because she was stressed...." It was only after repeated emails to both Facewatch and Home Bargains that she eventually found there had been an allegation of theft of about £10 worth of toilet rolls on 8 May. Her picture had somehow been circulated to local stores alerting them that they should not allow her entry. Ms. Horan said she checked her bank account to confirm she had indeed paid for the items before Facewatch eventually responded to say a review of the incident showed she had not stolen anything. "Because I was persistent I finally got somewhere but it wasn't easy, it was really stressful," she said. "My anxiety was really bad — it really played with my mind, questioning what I've done for days. I felt anxious and sick. My stomach was turning for a week." In one email from Facewatch seen by the BBC, the firm told Ms Horan it "relies on information submitted by stores" and the Home Bargains branches involved had since been "suspended from using the Facewatch system". Madeleine Stone, senior advocacy officer at the civil liberties campaign group Big Brother Watch, said they had been contacted by more than 35 people who have complained of being wrongly placed on facial recognition watchlists. "They're being wrongly flagged as criminals," Ms Stone said. "They've given no due process, kicked out of stores," adds the senior advocacy officer. "This is having a really serious impact." The group is now calling for the technology to be banned. "Historically in Britain, we have a history that you are innocent until proven guilty but when an algorithm, a camera and a facial recognition system gets involved, you are guilty. The Department for Science, Innovation and Technology said: "While commercial facial recognition technology is legal in the UK, its use must comply with strict data protection laws. Organisations must process biometric data fairly, lawfully and transparently, ensuring usage is necessary and proportionate. "No one should find themselves in this situation."

  • New York State Begins Asking Employers to Offically Identify Layoffs Caused by AI
    2025-06-15T16:34:00+00:00
    The state of New York is "asking companies to disclose whether AI is the reason for their layoffs," reports Entrepreneur: The move applies to New York State's existing Worker Adjustment and Retraining Notification (WARN) system and took effect in March, Bloomberg reported. New York is the first state in the U.S. to add the disclosure, which could help regulators understand AI's effects on the labor market. The change takes the form of a checkbox added to a form employers fill out at least 90 days before a mass layoff or plant closure through the WARN system. Companies have to select whether "technological innovation or automation" is a reason for job cuts. If they choose that option, they are directed to a second menu where they are asked to name the specific technology responsible for layoffs, like AI or robots.

  • 17-Year-Old Student Builds 3D-printed Drone In Garage, Interests DoD and MIT
    2025-06-15T15:34:00+00:00
    "Cooper Taylor is only 17 years old, but he's already trying to revolutionize the drone industry," writes Business Insider: His design makes the drone more efficient, customizable, and less expensive to construct, he says. He's built six prototypes, 3D printing every piece of hardware, programming the software, and even soldering the control circuit board. He says building his drone cost one-fifth of the price of buying a comparable machine, which sells for several thousand dollars. Taylor told Business Insider he hopes that "if you're a first responder or a researcher or an everyday problem solver, you can have access to this type of drone." His innovation won him an $8,000 scholarship in April at the Junior Science and Humanities Symposium, funded by the Defense Department. Then, on May 16, he received an even bigger scholarship of $15,000 from the US Navy, which he won after presenting his research at the Regeneron International Science and Engineering Fair... It all started when Taylor's little sister got a drone, and he was disappointed to see that it could fly for only about 30 minutes before running out of power. He did some research and found that a vertical take-off and landing, or VTOL, drone would last longer. This type of drone combines the multi-rotor helicopter style with the fixed wings of an airplane, making it extremely versatile. It lifts off as a helicopter, then transitions into plane mode. That way, it can fly farther than rotors alone could take it, which was the drawback to Taylor's sister's drone. Unlike a plane-style drone, though, it doesn't need a runway, and it can hover with its helicopter rotors. Taylor designed a motor "that could start out helicopter-style for liftoff, then tilt back to become an airplane-style motor," according to the article. And now this summer he'll be "working on a different drone project through a program with the Reliable Autonomous Systems Lab at the Massachusetts Institute of Technology." Thanks to Slashdot reader Agnapot for sharing the news.

  • Site for 'Accelerating' AI Use Across the US Government Accidentally Leaked on GitHub
    2025-06-15T14:34:00+00:00
    America's federal government is building a website and API called ai.gov to "accelerate government innovation with AI", according to an early version spotted by 404 Media that was posted on GitHub by the U.S. government's General Services Administration. That site "is supposed to launch on July 4," according to 404 Media's report, "and will include an analytics feature that shows how much a specific government team is using AI..." AI.gov appears to be an early step toward pushing AI tools into agencies across the government, code published on Github shows.... The early version of the page suggests that its API will integrate with OpenAI, Google, and Anthropic products. But code for the API shows they are also working on integrating with Amazon Web Services' Bedrock and Meta's LLaMA. The page suggests it will also have an AI-powered chatbot, though it doesn't explain what it will do... Currently, AI.gov redirects to whitehouse.gov. The demo website is linked to from Github (archive here) and is hosted on cloud.gov on what appears to be a staging environment. The text on the page does not show up on other websites, suggesting that it is not generic placeholder text... In February, 404 Media obtained leaked audio from a meeting in which [the director of the GSA's Technology Transformation Services] told his team they would be creating "AI coding agents" that would write software across the entire government, and said he wanted to use AI to analyze government contracts.

  • Do People Actually Want Smart Glasses Now?
    2025-06-15T11:34:00+00:00
    It's the technology "Google tried (and failed at) more than a decade ago," writes CNN. (And Meta and Amazon have also previously tried releasing glasses with cameras, speakers and voice assistants.) Yet this week Snap announced that "it's building AI-equipped eyewear to be released in 2026." Why the "renewed buzz"? CNN sees two factors: - Smartphones "are no longer exciting enough to entice users to upgrade often." - "A desire to capitalize on AI by building new hardware around it." Advancements in AI could make them far more useful than the first time around. Emerging AI models can process images, video and speech simultaneously, answer complicated requests and respond conversationally... And market research indicates the interest will be there this time. The smart glasses market is estimated to grow from 3.3 million units shipped in 2024 to nearly 13 million by 2026, according to ABI Research. The International Data Corporation projects the market for smart glasses like those made by Meta will grow from 8.8 in 2025 to nearly 14 million in 2026.... Apple is also said to be working on smart glasses to be released next year that would compete directly with Meta's, according to Bloomberg. Amazon's head of devices and services Panos Panay also didn't rule out the possibility of camera-equipped Alexa glasses similar to those offered by Meta in a February CNN interview. "But I think you can imagine, there's going to be a whole slew of AI devices that are coming," he said in February." More than two million Ray-Ban Meta AI glasses have been sold since their launch in 2023, the article points out. But besides privacy concerns, "Perhaps the biggest challenge will be convincing consumers that they need yet another tech device in their life, particularly those who don't need prescription glasses. The products need to be worth wearing on people's faces all day." But still, "Many in the industry believe that the smartphone will eventually be replaced by glasses or something similar to it," says Jitesh Ubrani, a research manager covering wearable devices for market research firm IDC. "It's not going to happen today. It's going to happen many years from now, and all these companies want to make sure that they're not going to miss out on that change."

  • Space is the Perfect Place to Study Cancer and Someday Even Treat It
    2025-06-15T07:34:00+00:00
    Space may be the perfect place to study cancer — and someday even treat it," writes Space.com: On Earth, gravity slows the development of cancer because cells normally need to be attached to a surface in order to function and grow. But in space, cancer cell clusters can expand in all directions as bubbles, like budding yeast or grapes, said Shay Soker, chief science program officer at Wake Forest's Institute for Regenerative Medicine. Since bubbles grow larger and more quickly in space, researchers can more easily test substances clinging to the edge of the larger bubbles, too. Scientists at the University of Notre Dame are taking advantage of this quirk to develop an in-space cancer test that needs just a single drop of blood. The work builds on a series of bubble-formation experiments that have already been conducted on the ISS. "If cancer screening using our bubble technology in space is democratized and made inexpensive, many more cancers can be screened, and everyone can benefit," said Tengfei Luo, a Notre Dame researcher who pioneered the technology, speaking to the ISS' magazine, Upward. "It's something we may be able to integrate into annual exams. It sounds far-fetched, but it's achievable...." Chemotherapy patients could save precious time, too. In normal gravity, they typically have to spend a half-hour hooked up to a needle before the medicine begins to take effect, because most drugs don't dissolve easily in water. But scientists at Merck have discovered that, in space, their widely used cancer drug pembrolizumab, or Keytruda, can be administered through a simple injection, because large crystalline molecules that would normally clump together are suspended in microgravity... Someday, microgravity could even help patients recovering from surgery heal faster than they would on Earth, Soker added. "Wound healing in high pressure is faster. That's the hyperbaric treatment for wounds...." For the Wake Forest experiment, which is scheduled to launch next spring, scientists will cut out two sections of a cancer tumor from around 20 patients. One sample will stay on Earth while the other heads to the ISS, with scientists observing the difference. The testing will be completed within a week, to avoid any interference from cosmic radiation. If successful, Soker said, it could set the stage for diagnostic cancer tests in space available to the general population — perhaps on a biomedical space station that could launch after the planned demise of the ISS. "Can we actually design a special cancer space station that will be dedicated to cancer and maybe other diseases?" Shoker asked, answering his question in the affirmative. "Pharmaceutical companies that have deep pockets would certainly support that program."

  • Executives from Meta, OpenAI, and Palantir Commissioned Into the US Army Reserve
    2025-06-15T03:49:00+00:00
    Meta's CTO, Palantir's CTO, and OpenAI's chief product officer are being appointed as lieutenant colonels in America's Army Reserve, reports The Register. (Along with OpenAI's former chief revenue officer). They've all signed up for Detachment 201: Executive Innovation Corps, "an effort to recruit senior tech executives to serve part-time in the Army Reserve as senior advisors," according to the official statement. "In this role they will work on targeted projects to help guide rapid and scalable tech solutions to complex problems..." "Our primary role will be to serve as technical experts advising the Army's modernization efforts," [Meta CTO Andrew Bosworth] said on X... As for Open AI's involvement, the company has been building its ties with the military-technology complex for some years now. Like Meta, OpenAI is working with Anduril on military ideas and last year scandalized some by watering down its past commitment to developing non-military products only. The Army wasn't answering questions on Friday but an article referenced by [OpenAI Chief Product Officer Kevin] Weil indicated that the four will have to serve a minimum of 120 hours a year, can work remotely, and won't have to pass basic training...

  • Python Creator Guido van Rossum Asks: Is 'Worse is Better' Still True for Programming Languages?
    2025-06-15T01:49:00+00:00
    In 1989 a computer scientist argued that more functionality in software actually lowers usability and practicality — leading to the counterintuitive proposition that "worse is better". But is that still true? Python's original creator Guido van Rossum addressed the question last month in a lightning talk at the annual Python Language Summit 2025. Guido started by recounting earlier periods of Python development from 35 years ago, where he used UNIX "almost exclusively" and thus "Python was greatly influenced by UNIX's 'worse is better' philosophy"... "The fact that [Python] wasn't perfect encouraged many people to start contributing. All of the code was straightforward, there were no thoughts of optimization... These early contributors also now had a stake in the language; [Python] was also their baby"... Guido contrasted early development to how Python is developed now: "features that take years to produce from teams of software developers paid by big tech companies. The static type system requires an academic-level understanding of esoteric type system features." And this isn't just Python the language, "third-party projects like numpy are maintained by folks who are paid full-time to do so.... Now we have a huge community, but very few people, relatively speaking, are contributing meaningfully." Guido asked whether the expectation for Python contributors going forward would be that "you had to write a perfect PEP or create a perfect prototype that can be turned into production-ready code?" Guido pined for the "old days" where feature development could skip performance or feature-completion to get something into the hands of the community to "start kicking the tires". "Do we have to abandon 'worse is better' as a philosophy and try to make everything as perfect as possible?" Guido thought doing so "would be a shame", but that he "wasn't sure how to change it", acknowledging that core developers wouldn't want to create features and then break users with future releases. Guido referenced David Hewitt's PyO3 talk about Rust and Python, and that development "was using worse is better," where there is a core feature set that works, and plenty of work to be done and open questions. "That sounds a lot more fun than working on core CPython", Guido paused, "...not that I'd ever personally learn Rust. Maybe I should give it a try after," which garnered laughter from core developers. "Maybe we should do more of that: allowing contributors in the community to have a stake and care".
