  • Meta Pauses Employee-Tracking Program Following Internal Data Leak
    by BeauHD on 24/06/2026 at 10:00 pm

    Meta has paused its Model Compatibility Initiative that tracked employee mouse movements, clicks, keystrokes, and screen content to train AI agents, after some of its collected data became accessible to more employees than intended. Meta says it has no evidence the information was improperly accessed and will not restart the program until it is confident in its safeguards. Wired reports: Meta rolled out the Model Compatibility Initiative (MCI) tool in April to US employees. The tool "collects computer inputs such as mouse movements, click locations and keystrokes, as well as screen content," according to workers who have been petitioning against it over privacy, security, and personal liberty concerns. When MCI launched, employees couldn't opt out, but that changed to a limited degree after workers protested. Meta executives have repeatedly defended the data-gathering project, saying it was necessary to train AI systems to operate computer software the way humans do and that employees were the best examples for the artificial intelligence to learn from. On Monday, a Meta engineer issued an internal security notice stating that databases filled with information gathered by MCI had been exposed to anyone inside the company. A former employee actively involved in pushing back against MCI describes the lapse as "a mess" -- and one that employees had expected would occur. "When workers raised concerns, leadership doubled down and failed to acknowledge the risks workers raised about the safety and privacy of worker and customer data," the person says. "Leadership has clearly created an authoritarian environment where workers are no longer respected or heard." But after critical comments poured into internal forums on Monday expressing frustration about the security issue, Meta shocked some of its staff by pausing MCI altogether, telling WIRED about the development several hours before announcing it to employees. A few workers told WIRED they were confused in the meantime because the tool was continuing to run on their laptops. Late on Monday, Stephane Kasriel, a Meta vice president overseeing AI research, announced the pause and told staff that the security issue had been discovered on June 18 and addressed within four hours. But the initial fix didn't stick and access to the data had to be further locked down. The issue made "some MCI-derived data" accessible to more people than intended, he wrote, without elaborating.

  • GTA VI Is a Worrying Sign For the Future of Physical Games
    by BeauHD on 24/06/2026 at 9:00 pm

    Rockstar Games has revealed the price of Grand Theft Auto VI to be $79.99, and confirmed that the physical versions of the game won't include a disc. Instead, they'll contain a one-time download code when it launches November 19. "Not only is that a disappointing decision for people who like to own physical games, but given the scale of the next GTA, it also sets a bad precedent for the rest of the industry," reports The Verge. From the report: There are a lot of advantages to buying digital. You can start a download from your couch. You can store multiple games on one hard drive so you don't have to get up to play something else. Storefronts like Steam or the PlayStation Store don't run out of inventory of the newest game you're interested in, and you can often get games at a cheaper price thanks to frequent sales. But it's becoming increasingly clear that digital ownership has significant disadvantages, too. If a game you don't own digitally is removed from a storefront, whether that's for things like licensing, artificially limited availability, or even the store eventually closing down, your only option is to hope you can find a physical version. If your account on a platform is banned, even if that ban isn't warranted, you might be locked out of your digital library with no way to play those games unless you buy them again or hope your account gets restored. You can't sell or trade digital games you've purchased, and while there are ways to share digital games, they require some work and are usually intended just for families. It's also much harder to preserve digital games because they only "exist" on the hard drive of a console, PC, or device they were downloaded to. This is an issue across many industries, not just console games; there are multiple examples of things like mobile games and streaming shows becoming lost for good when they don't have a physical version. Without physical versions, you also can't find a used version of a game at a garage sale or a local game shop. It's unclear whether Rockstar will ever release a physical version of the game. As for why, The Verge suspects the decision was made in part to prevent leaks; "by only being available digitally, Rockstar can ensure that GTA VI unlocks at the same exact time for everyone." "The digital-only choice might also indicate that the game has a massive file size that's too big for PlayStation and Xbox game discs." Read more of this story at Slashdot.

  • OpenAI Unveils First Chip As Part of Broadcom Deal
    by BeauHD on 24/06/2026 at 8:00 pm

    OpenAI and Broadcom have unveiled Jalapeno, OpenAI's first custom AI chip, designed primarily to handle inference for ChatGPT and other services. It's a major step in OpenAI's plan to "build the full stack behind its models and products," says OpenAI. "By designing more of the stack ourselves, we can serve more intelligence with greater efficiency and keep pushing advanced AI toward broader access." CNBC reports: The chip with Broadcom is an ASIC, which industry experts say is less flexible than Nvidia's GPU, but is also less expensive and can be designed for specific AI tasks. OpenAI said that it designed the chip in nine months, and that it also crafted large parts of the computer system where it will be used. The companies are calling the chip an "Intelligence Processor" and describe it as the first "AI accelerator" in a platform they're building "to make advanced AI faster, more reliable, and more accessible to more people." [...] A physical sample of the new chip will be delivered to OpenAI on Wednesday. The companies said they're aiming for initial deployment of the Jalapeno chips by the end of 2026, "expanding in the years ahead." Read more of this story at Slashdot.

  • Walmart's First Nuclear Deal Shows Demand Beyond AI Data Centers
    by BeauHD on 24/06/2026 at 7:00 pm

    An anonymous reader quotes a report from Barron's: Walmart is signing a long-term contract to buy nuclear power for the first time ever, a promising sign that the industry's future is supported by more than just the AI data center boom. The retail giant agreed on Tuesday to buy power from a nuclear plant in Illinois owned by Constellation Energy for its operations in the area, including its stores and a high-tech warehouse in Illinois that stores and sorts perishable food. Walmart will buy 176 megawatts of power from the plant over a 15-year period, or enough power to serve around 150,000 homes. The Walmart deal will allow Constellation to expand the capacity of the Illinois plant by 30 megawatts, a process known as an uprate, which can involve replacing older equipment and improving efficiency. Walmart, which has pledged to eliminate net carbon emissions from its U.S. operations by 2040, will also receive the environmental attributes associated with the nuclear energy, which generates electricity without carbon emissions.

  • Bob Iger's Disney Wanted Apple, Twitter, and 007
    by BeauHD on 24/06/2026 at 6:00 pm

    In an exit interview with The Financial Times (paywalled), former Disney CEO Bob Iger says the company seriously considered buying Twitter, explored a potential merger with Apple, and pursued the James Bond franchise during his tenure. The Verge reports: According to Iger, Disney came close to buying Twitter from co-founder Jack Dorsey "at a very attractive price," sometime prior to Elon Musk buying the social media platform in 2022 and changing its name to X. Iger had plans to turn Twitter into a global distribution platform for Disney, but walked away on the morning of the deal over concerns that it would be "a horrible distraction." Disney was also at one point involved in early conversations regarding a potential merger with Apple, something Iger thinks would have been "truly transformational." In the end, Iger says these conversations "never went anywhere," and that "Apple didn't show that much interest." The two companies have a mixed history -- Iger was an Apple board member from 2011 to 2019, and notably a driving force behind Disney acquiring Pixar in 2006, which was led by Apple co-founder Steve Jobs at the time. According to Iger, his first call with Jobs resulted in an almost immediate deal to put Disney content on the first video iPod. "All of a sudden, I'm now someone Steve likes and respects," Iger told The Financial Times. "The old Disney that he knew was lumbering in terms of bureaucracy. And so he thought, this is a new day." The Pixar acquisition spurred Iger to find more companies to bring under Disney's wing, though not every attempt was successful. "We felt unstoppable. We put together a list of acquisition targets," said Iger. "Marvel was one, Star Wars was another, James Bond was one. We had a list and I figured let's just tick them off and buy them all." Iger provides no details about Disney's attempt to buy the James Bond franchise, but we know it obviously failed -- Amazon bought the 007 distribution rights when it acquired MGM in 2022, and later paid more than $1 billion to take full creative control of the franchise in February 2025.

  • Boffin Claims Microsoft's 'Quantum Leap' Is Invalid Due To 'Basic Python Errors'
    by BeauHD on 24/06/2026 at 5:00 pm

    A peer-reviewed Nature critique argues that Microsoft's 2025 Majorana quantum-computing breakthrough -- and its claim that it could enable "a truly meaningful quantum computer not in decades, as some have predicted, but in years" -- is fundamentally flawed. According to Dr Henry Legg, a lecturer at the University of St Andrews, the claims were undermined by omitted data, selective plotting, and basic Python errors that concealed alternative results. Microsoft, for its part, says the bugs were minor and stands by its findings and roadmap. The Register reports: "Last year they claimed to be years, not decades from a 'topological quantum supercomputer,'" Legg told The Register in an email. "My feeling is that they are centuries, not decades away. If it works at all -- and, based on what I have seen, the most likely scenario is that it doesn't work." Based on his analysis of the research Microsoft published in 2025, Legg argues that the company's claims about finding and being able to control the elusive Majorana particle to build a topological superconductor do not withstand scrutiny. "I demonstrate that Microsoft's tune-up software is flawed and that coding errors resulted in incorrect statements to peer reviewers," said Legg. "Raw data, which was omitted from the original paper, also appears to indicate Microsoft's devices contain considerable disorder and are not compatible with the existence of a topological gap. In other words, the prerequisites for Microsoft's claims do not appear to be met, but this was obscured because this data did not appear in the original publication." Essentially, Microsoft has proposed a Topological Gap Protocol (TGP) that can be used to detect the phase transition deemed to be a prerequisite for conducting quantum calculations using Majorana particles. Legg argues that based on his analysis of underlying transport data (measurements of particle change) -- omitted from the original publication -- Microsoft chose to focus on results that supported its thesis and ignored data that could be interpreted as a negative result. As he notes in his critique: "The TGP plotting code was set to highlight only the largest purportedly topological region." "The primary consequence was the omission of other regions that passed their tune-up protocol (the TGP)," said Legg. "When peer reviewers asked if other regions existed, Microsoft inaccurately stated that they had investigated the only region passing the protocol within the explored range. This was not correct." Legg also argues that Microsoft mishandled its code. "The code antisymmetrized bias voltage based on array index rather than physical value," his analysis says. In other words, Microsoft's researchers made a basic programming mistake by evaluating the array index -- the number identifying a value's position in an array -- instead of the value to which the index refers. "There were two pretty basic Python programming errors that hid these alternative regions," Legg explained. "Their plotting software was hardcoded with a filter (zbp_cluster_numbers=[1]) that forced it to display only the single largest region, concealing other successful results from their phase maps. Changing this to zbp_cluster_numbers=[1,2] shows already a second region." Legg added: "The TGP software transformed the data by simply reversing a Python array (x[::-1]) based on its index position, ignoring the actual physical bias voltages."
