  • Valve Reveals Its the Architect Behind a Push To Bring Windows Games To Arm
    by BeauHD on 04/12/2025 at 3:03 am

    An anonymous reader quotes a report from The Verge's Sean Hollister If you wrote off the Steam Frame as yet another VR headset few will want to wear, I guarantee you're not alone. But the Steam Frame isn't just a headset; it's a Trojan horse that contains the tech gamers need to play Steam games on the next Samsung Galaxy, the next Google Pixel, perhaps Arm gaming notebooks to come. I know, because I'm already using that tech on my Samsung Galaxy. There is no official Android version of Hollow Knight: Silksong, one of the best games of 2025, but that doesn't have to stop you anymore. Thanks to a stack of open-source technologies, including a compatibility layer called Proton and an emulator called Fex, games that were developed for x86-based Windows PCs can now run on Linux-based phones with the Arm processor architecture. With Proton, the Steam Deck could already do the Windows-to-Linux part; now, Fex is bridging x86 and Arm, too. This stack is what powers the Steam Frame's own ability to play Windows games, of course, and it was widely reported that Valve is using the open-source Fex emulator to make it happen. What wasn't widely reported: Valve is behind Fex itself. In an interview, Valve's Pierre-Loup Griffais, one of the architects behind SteamOS and the Steam Deck, tells The Verge that Valve has been quietly funding almost all the open-source technologies required to play Windows games on Arm. And because they're open-source, Valve is effectively shepherding a future where Arm phones, laptops, and desktops could freely do the same. He says the company believes game developers shouldn't be wasting time porting games if there's a better way. Remember when the Steam Deck handheld showed that a decade of investment in Linux could make Windows gaming portable? Valve paid open-source developers to follow their passions to help achieve that result. Valve has been guiding the effort to bring games to Arm in much the same way: In 2016 and 2017, Griffais tells me, the company began recruiting and funding open-source developers to bring Windows games to Arm chips. Fex lead developer Ryan Houdek tells The Verge he chatted with Griffais himself at conferences those years and whipped up the first prototype in 2018. He tells me Valve pays enough that Fex is his full-time job. "I want to thank the people from Valve for being here from the start and allowing me to kickstart this project," he recently wrote.

  • AT&T and Verizon Are Fighting Back Against T-Mobile's Easy Switch Tool
    by BeauHD on 04/12/2025 at 2:02 am

    AT&T and Verizon are blocking T-Mobile's new "Switching Made Easy" tool that scans their customer accounts to recommend comparable plans. AT&T is also suing, alleging T-Mobile used bots to scrape over 100 fields of sensitive customer data. From The Mobile Report: According to a lawsuit, which AT&T has shared directly with us, T-Mobile updated the T-Life app's scraping abilities three separate times in an attempt to bypass AT&T's detection. Essentially, T-Mobile and AT&T have been in a game of cat and mouse. Not only that, but AT&T alleges that T-Mobile is intentionally hiding the fact that it's their scraper accessing an account, and essentially pretends to be an end user while doing so. Apparently, T-Mobile's scraping bot tries its best to appear as a generic web browser. AT&T sent T-Mobile a cease and desist letter on November 24th demanding T-Mobile stop the scraping process. T-Mobile responded two days later refusing, stating that the process was legal because "customers themselves ... log into their own wireless account." On November 26th, AT&T says they detected T-Mobile is no longer scraping the AT&T website, and instead asks users to upload a pdf of their bill or enter some info manually. They note, however, that at the time the app still appeared to scrape Verizon accounts. The lawsuit further explains that AT&T reached out to Apple with the claim that T-Mobile's T-Life app is also violating the App Store Review Guidelines. T-Mobile responded to this complaint as well, making similar claims that the scraping process does not violate those guidelines. [...] According to AT&T, the T-Life app collects way more information than is necessary for a simple carrier switch. The company alleges T-Mobile grabs over 100 separate bits of info from a customer's account, including info about other users on the account and other services not related to wireless service. It's also worth noting that, apparently, T-Mobile is storing this information, not just using it temporarily, even if the customer doesn't end up switching. T-Mobile has responded to our request for comment, and says that actually, AT&T is wrong about the facts, and Easy Switch is safe and secure... Read more of this story at Slashdot.

  • OpenAI Loses Fight To Keep ChatGPT Logs Secret In Copyright Case
    by BeauHD on 04/12/2025 at 1:01 am

    A federal judge has ordered OpenAI to hand over 20 million anonymized ChatGPT logs in its copyright battle with the New York Times and other outlets. Reuters reports: U.S. Magistrate Judge Ona Wang in a decision made public on Wednesday said that the 20 million logs were relevant to the outlets' claims and that handing them over would not risk violating users' privacy. The judge rejected OpenAI's privacy-related objections to an earlier order requiring the artificial intelligence startup to submit the records as evidence. "There are multiple layers of protection in this case precisely because of the highly sensitive and private nature of much of the discovery," Wang said. An OpenAI spokesperson on Wednesday cited an earlier blog post from the company's Chief Information Security Officer Dane Stuckey, which said the Times' demand for the chat logs "disregards long-standing privacy protections" and "breaks with common-sense security practices." OpenAI has separately appealed Wang's order to the case's presiding judge, U.S. District Judge Sidney Stein. A group of newspapers owned by Alden Global Capital's MediaNews Group is also involved in the lawsuit. MediaNews Group executive editor Frank Pine said in a statement on Wednesday that OpenAI's leadership was "hallucinating when they thought they could get away with withholding evidence about how their business model relies on stealing from hardworking journalists."

  • White House Rolls Back Fuel Economy Standards
    by BeauHD on 04/12/2025 at 12:00 am

    Longtime Slashdot reader sinij shares a report from Car and Driver: [T]he Trump administration announced less stringent Corporate Average Fuel Economy (CAFE) standards in an effort to bring down the price of new vehicles. The administration says that rules put in place by the Biden administration broke the law by going beyond the requirements mandated by Congress when the CAFE program was started. The new regulations will require automakers to meet an average fuel-economy figure of 34.5 mpg across 2031-model-year vehicles, instead of the 50.4 mpg that would have been required under the previous regulations. sinij comments: "This is a much-needed move as they also recently closed a number of loopholes, such as the assumed fuel-savings credit for engine start-stop technology, that made it more difficult to meet these goals. More so, a recent string of engine and transmission failures from multiple manufacturers shows that meeting fleet standards came at a very significant cost of reduced reliability."

  • The Last Video Rental Store Is Your Public Library
    by BeauHD on 03/12/2025 at 11:23 pm

    404 Media's Claire Woodcock writes: As prices for streaming subscriptions continue to soar and finding movies to watch, new and old, is becoming harder as the number of streaming services continues to grow, people are turning to the unexpected last stronghold of physical media: the public library. Some libraries are now intentionally using iconic Blockbuster branding to recall the hours visitors once spent looking for something to rent on Friday and Saturday nights. John Scalzo, audiovisual collection librarian with a public library in western New York, says that despite an observed drop-off in DVD, Blu-ray, and 4K Ultra disc circulation in 2019, interest in physical media is coming back around. "People really seem to want physical media," Scalzo told 404 Media. Part of it has to do with consumer awareness: People know they're paying more for monthly subscriptions to streaming services and getting less. The same has been true for gaming. As the audiovisual selector with the Free Library of Philadelphia since 2024, Kris Langlais has been focused on building the library's video game collections to meet comparable interest in demand. Now that every branch library has a prominent video game collection, Langlais says that patrons who come for the games are reportedly expressing interest in more of what the library has to offer. "Librarians out in our branches are seeing a lot of young people who are really excited by these collections," Langlais told 404 Media. "Folks who are coming in just for the games are picking up program flyers and coming back for something like that." IP disputes are fueling the shift, too. The report notes how rights and licensing battles are making some films harder to access -- from titles that quietly slip out of commercial circulation, to streaming-only releases that never make it to disc, to entire shows vanishing during mergers like HBO Max-Discovery+. One prominent example is The People's Joker, which was briefly pulled from the Toronto International Film Festival over a conflict with Batman's rightsholders. Situations like that are pushing librarians to grab physical copies while they still can, before these works risk disappearing altogether. Read more of this story at Slashdot.

  • After AI Push, Trump Administration Is Now Looking To Robots
    by BeauHD on 03/12/2025 at 10:22 pm

    An anonymous reader quotes a report from Politico: Five months after releasing a plan to accelerate the development of artificial intelligence, the Trump administration is turning to robots. Commerce Secretary Howard Lutnick has been meeting with robotics industry CEOs and is "all in" on accelerating the industry's development, according to three people familiar with the discussions who were granted anonymity to share details. The administration is considering issuing an executive order on robotics next year, according to two of the people. A Department of Commerce spokesperson said: "We are committed to robotics and advanced manufacturing because they are central to bringing critical production back to the United States." The Department of Transportation is also preparing to announce a robotics working group, possibly before the end of the year, according to one person familiar with the planning. A spokesperson for the department did not respond to a request for comment. There's growing interest on Capitol Hill as well. A Republican amendment to the National Defense Authorization Act would have created a national robotics commission. The amendment was not included in the bill. Other legislative efforts are underway. The flurry of activity suggests robotics is emerging as the next major front in America's race against China. "There is now recognition that advanced robotics is crucial to the U.S. in terms of manufacturing, technology, national security, defense applications, public safety," said Brendan Schulman, VP of policy and government relations for Boston Dynamics. "The investment that we're seeing in the sector and the efforts in China to dominate the future of robotics are being noticed." Read more of this story at Slashdot.
