  • Prada Unveils 'Liquid Cooling' Inner-Layer Garment for NASA's Moon Astronauts with Knitted-In Ventilation Tubes
    by EditorDavid on 07/06/2026 at 11:27 pm

    Italian fashion house Prada "unveiled on Sunday the inner-layer garment set to be worn by NASA astronauts heading to the moon," reports Reuters. "The body-hugging suit, created in collaboration with Houston-based space infrastructure developer Axiom Space, features ventilation tubes knitted into the garment." Expertise for developing space exploration products "can come from lots of seemingly unrelated industries," said Jonathan Cirtain, CEO of Axiom Space... The new product follows Prada's splashy foray into space fashion in 2024 with the unveiling of a spacesuit that is expected to be used for NASA's anticipated Artemis 4 moon landing in 2028... Other fashion and apparel companies have jumped on the space bandwagon. Under Armour has partnered with spaceflight company Virgin Galactic to create space apparel, while Columbia Sportswear has worked with space exploration company Intuitive Machines on space fabric technology. The new "Liquid Cooling and Ventilation Garment" was displayed on a mannequin at an event at Prada's Manhattan store. Read more of this story at Slashdot.

  • Black Market Tinkerers on Facebook Marketplace Offer to Hide 'Recording Lights' on Meta Smartglasses
    by EditorDavid on 07/06/2026 at 10:17 pm

    People are disabling the "recording light" on Meta's Ray-Ban smartglasses — "by my count, thousands of people," says tech journalist Joanna Stern in a new video report: STERN: "They're hiring people on Facebook Marketplace to drill out the light for as much as $100. According to our reporting, folks are offering this service in at least 30 states — despite Meta's attempts to stop it... In most states, we found multiple listings. In the New York and New Jersey area alone there were 23 listings." Stern watched a man in New Jersey disable and then conceal the light with a drill and dental probe in a New Jersey garage (a skill he learned watching YouTube and TikTok videos). He said the same day he'd already been contacted by eight more interested customers, and Stern also found at least 10 other people willing to do the same thing, just in New Jersey. "But what we found is they're all over the country." Meta sold 7 million smartglasses in 2025, but a Meta spokesperson insisted to the videomaker that a "majority" of their smartglasses owners aren't blocking the recording light. And furthermore, they added "We aggressively target anyone advertising tampering tools, have removed thousands of violating ads and Marketplace listings for these services, and pursue legal action when appropriate." (The reporter acknowledges "many" of the Marketplace ads disappeared after they brought them to Meta's attention — and Meta also said they were working with other retailers and sellers to take down listings for smartglasses-tampering parts.) The reporter also heard from one journalist who said they'd used it so they could record the activities of federal immigration agents without being targeted. "Others told me they just don't want people asking questions when they're recording." (There's video of one young man saying "It's already difficult enough to film in public. I don't want to have a blinking light on my face.") Tampering with smartglasses isn't illegal — though it is against Meta's Terms of Service, and could void your warranty. But a lawyer in the report says recording others without consent may be illegal, depending on a wide range of "jurisdictional nuances" like whether you live in an all-party consent state or a one-party consent state. "This seems to be our new reality," the report concludes: "more cameras, more microphones everywhere, and less certainty about who and what is recording." (Tech blogger John Gruber offered this assessment. "Using a Meta platform to find people to hack a Meta device so you can surreptitiously record strangers. So perfectly Meta.") Stern's report points out that "People are trying to fight back. Apps have popped up that use Bluetooth to scan for nearby camera glasses." (In the video one app-maker wonders why Meta isn't offering the same service themselves. "There are technical solutions to these problems.") Ironically, when I watched the report on YouTube, it was preceded by... an ad for Meta's Ray-Ban AI smartglasses. Read more of this story at Slashdot.

  • New Fortune 500 Rankings: Texas Overtakes California, But Amazon is #1, Beating Walmart
    by EditorDavid on 07/06/2026 at 8:29 pm

    "Texas has dethroned California as the state with the most Fortune 500 companies," reports the Los Angeles Times: The Fortune 500 list ranks the largest U.S. companies by revenue. This year, 57 of the top companies are headquartered in Texas, compared with California's 56. It's a reversal from two years ago when the Golden State had the pole position... California's corporate haters say they try to avoid the state's high costs, income taxes and strict regulations, but the western state is still a top money maker. "California dominates on nearly every other measure: its Fortune 500 companies are the most profitable ($647 billion), most valuable ($20 trillion), and employ more people than any other state (2.8 million workers)," Fortune said in a news release. Indeed, despite the naysayers, Californian companies have been leading the world in developing artificial intelligence technology as well as the latest in space and defense tech. The state is home to nearly 400 "unicorns," or billion-dollar startups — more than any other state, according to CB Insights. It also gobbled up nearly two-thirds of U.S. venture capital last year, with San Francisco Bay Area startups such as OpenAI leading the way, according to the business information platform Crunchbase. Texas and California have been in a tug-of-war for the crown. In 2024, after a decade, California bagged the top spot with 57 companies on the list, while Texas and New York tied in second with 52 companies each... The fourth spot was tied between Illinois and Ohio, with 29 companies each. Amazon was the top company on the list, ending Walmart's 13-year reign at the top of the annual Fortune 500 companies list. Amazon's 2025 revenue was $716.9 billion, compared with Walmart's $713.2 billion. Seattle-headquartered Amazon joined Exxon Mobil, General Motors, and Walmart as the only four companies to have ever held the top position since Fortune began publishing the data in 1955.

  • The Gamer-Rights Group Fighting to Make the Industry Stop Killing Games (Servers)
    by EditorDavid on 07/06/2026 at 7:10 pm

    "Can a company take away something you've already paid for?" asks the BBC. "In the world of online video games, some already do." Publishers can decide to switch off a game's servers, often leaving it effectively unplayable. Stop Killing Games, a growing consumer rights campaign started by American YouTuber Ross Scott in 2024, is challenging that practice. In January, the group submitted a petition featuring nearly 1.3 million signatures to the European Commission, triggering a public hearing in the European Parliament in April. What began as an online campaign is now awaiting a decision from one of the EU's most powerful institutions... Scott's campaign began following an announcement from the major studio Ubisoft, saying it would shut down the online-only racing game The Crew in 2024... Ubisoft has already defended its position in court. Responding to a proposed class-action lawsuit brought by two The Crew players in California, the studio argued that customers had purchased a licence to use the game, not unlimited ownership rights, and that players had been warned online services would not be available forever. The lawsuit was dismissed without prejudice in June 2025, after the plaintiffs voluntarily withdrew the case. The wider games industry has also pushed back against the campaign. Video Games Europe, which represents many of the industry's largest publishers, said shutting down online services "must be an option" when games are no longer commercially viable. It also warned that some of the campaign's proposals could make online-only games significantly more expensive to develop. "In no way are we asking companies to keep servers running or services going, they can end it any time they want," said Scott. Instead, he and his fellow campaigners argue that when a game is shut down it should be done "responsibly", with publishers considering "end-of-life plans" such as updating the game to work offline or releasing software that allows players to continue running it. Two key points from the article: "In March, French consumer group UFC-Que Choisir launched legal action against Ubisoft over the shutdown of The Crew, arguing that players were misled about the permanence of their purchase and that some of the company's contract terms were unfair." "The European Commission must respond to the European Citizens' Initiative — the petition brought by the group — by 27 July."

  • Winners Announced in 2026's 'International Obfuscated C Code Competition'
    by EditorDavid on 07/06/2026 at 5:34 pm

    Yesterday 2026's International Obfuscated C Code Contest concluded, with 22 new winners announced in a special three-hour livestreamed ceremony! Started 42 years ago, it's been described as the internet's longest-running contest, with entrants concocting convoluted programs glorying in the C programming language's subtleties, all while having some fun. And "For IOCCC29, the volume and quality of submissions were at near-historic heights," explains its home page. There's a "Tetris-optimized" GameBoy emulator with source code that looks like a GameBoy, as well as a quasi-Rogue-like game voted "most likely to teleport." Awards were also given for the best imaginary emulator (a virtual machine in 366 bytes of C) and the best fractional emulator (a maze generator for the Commodore 64). But every one of the 22 winning programs seems wildly creative... Quine Pong. "Running the program produces the source code to generate the next frame, formatted to display the current frame. By repeatedly compiling and running each successive frame, you can play the game. To move, pass either "w" (up) or "e" (down) as an argument..." A winning Taiwanese programmer formatted their source code in the shape of a Tardis from Doctor Who — code that displays an intricate ASCII animation of Doctor Who's 1963 opening title sequence. One winning entry emulates an IBM 7040 mainframe, first converting a program (encoded in whitespace) into ASCII-character drawings of punchcards for a FORTRAN program — and then executing that program to calculate the light visible to an observer looking at black hole, ultimately creating an image. It's all recreating what astrophysicist Jean-Pierre Luminet had to do in 1978 to generate the first-ever simulated photograph of a black hole (on an IBM 7040 mainframe). "The entry can also run other FORTRAN programs — but "they must be provided as a deck of punch cards... Tools have been provided to convert to/from decks and to interpret..." "We have added fun challenges to this year's winning entries competition..." the web site notes. "After you figure out what a given winning entry does, we encourage you to attempt the fun challenge!" Thanks to long-time Slashdot reader achowe for bringing the news (who has submitted winning entries in four different decades, starting in 1991 and continuing through 2025) — and who won again this year for a program simulating the Space Invaders-like game from Casio's 1980 MG-880 calculator.

  • James Bond Videogame '007 First Light' Sells 3M Copies, Earns $150M
    by EditorDavid on 07/06/2026 at 4:34 pm

    The new James Bond-themed videogame 007 First Light had a budget of 1.3 billion Danish krone — a little more than USD $202 million, reports IGN, citing a report from Denmark's public service broadcaster. "Denmark's TV 2 said that makes 007 First Light the most expensive entertainment product in the country's history" — and the game "still has some way to go before breaking even." 007 First Light is estimated to have sold 2.2 million copies, generating $150 million in revenue... [Saturday IGM reported sales had jumped to 3 million copies.] The only official sales data we have comes from developer IO Interactive, which said that 007 First Light had become the fastest-selling game in the company's history, shifting 1.5 million copies in its first 24 hours... The impressive sales milestone was achieved without the aid of the Nintendo Switch 2 version, which is due out this summer. The James Bond adventure is also the highest rated IOI game ever, with an 87 on Metacritic... The developer has said it wants to make a trilogy of James Bond games. Game-tracking company Alinea Analytics tweeted their estimates that 55.1% of sales were on PS5, 33.1% on Steam, and 11.8% on Xbox (Xbox console, Windows, and cloud combined). And Polygon reports that new downloadable game content was announced Friday. Read more of this story at Slashdot.
