  • China Broadens Travel Curbs To Encompass Family of Top AI Talent
    by BeauHD on 28/09/2026 at 11:00 pm

    Longtime Slashdot reader schwit1 shares a report from Business Standard: China has expanded overseas travel restrictions for top AI professionals in private firms to include the families of key personnel, further tightening measures designed to prevent the outflow of critical know-how and information to the US. Government agencies have recently begun to share the wider restrictions with affected people, which include prominent startup founders as well as the heads of strategically important companies in AI-related fields, people familiar with the matter said. Direct relatives such as spouses and children of certain AI and chip executives, whose work is considered paramount to state security, are now required to obtain approval from Beijing before going abroad even for short trips, the people said. That marks a broadening of existing curbs on the freedom of movement of China's most influential tech talent -- a category that encompasses entrepreneurs, researchers and executives. While not an outright ban on travel, the new requirement is likely to exert a further chilling effect on a tech sector already facing unprecedented curbs. China has restricted foreign travel for top AI professionals in private firms such as Alibaba Group Holding Ltd and DeepSeek since earlier this year, Bloomberg News reported in May, reflecting Beijing's determination to safeguard its technology as it makes big strides in AI and chipmaking. It's unclear whether all those people's families need to follow the new strictures, the people said. China is also separately implementing rules, which became effective Sept 15, for enforcing exit bans in cases ranging from criminal investigations to potential violations of the country's industrial and technological security. Beijing's plan is to add relevant individuals to the list as time goes by, the people said, asking not to be identified discussing a sensitive issue. Government departments have already notified several people of the need to clear family travel, two of the people said. Read more of this story at Slashdot.

  • AMD Acquires Fei-Fei Li's World Labs For $8.2 Billion
    by BeauHD on 28/09/2026 at 10:00 pm

    AMD has agreed to acquire Fei-Fei Li's World Labs for about $8.2 billion in stock, making it the chipmaker's second-largest acquisition and giving it a major foothold in "world models" that simulate 3D environments for robotics and other physically grounded AI. CNBC reports: AI researchers expect world models will be able to help develop robots and other physically-grounded artificial intelligence applications. AMD plans to keep World Labs separate from its chipmaking business until the transaction closes later this year. The lab's research on next-generation models will allow AMD to plan for what its AI chips need to be capable of years in advance. World Labs was founded by AI researcher Fei-Fei Li, who is widely seen as an AI pioneer as a Stanford professor, and who previously worked for Google leading AI research. Li will become an AMD's chief scientist and an executive vice president at the company. In a demo presented by Li and AMD CEO Lisa Su earlier this year, the two executives showed a World Labs model called Marble creating a three-dimensional scene out of a few images. "Intelligent agents, whether it's robots or vehicles or even tools, can learn inside very-rich physics-aware digital worlds before they even need to be deployed into the real one, making them much safer," Li said at the presentation.

  • TikTok to Pay Alabama $100 Million, Limit Teen Use In First State Settlement
    by BeauHD on 28/09/2026 at 9:00 pm

    TikTok has agreed to pay Alabama at least $100 million and adopt new restrictions for teenage users, including a two-hour daily limit, overnight access restrictions, stronger age verification, a ban on beauty filters, and an option for a non-personalized feed. The settlement could grow to as much as $300 million if enough other state attorneys general join similar agreements. The Guardian reports: A trial had been set to begin on Monday in the southern US state over claims by Alabama that TikTok misled parents about tools meant to shield children from harmful content. [...] Attorney general Steve Marshall hailed Friday's settlement as "a great day for Alabama parents." He said: "Tonight, they can rest easier knowing real protections are in place to shield their children from the dangers of social media addiction." Under the settlement, TikTok will send $100m to Alabama and could possibly pay up to $300m in total if 40 other attorneys general sign similar agreements with the company within a specified timeframe. In addition, the Alabama deal includes a conditional restriction that Meta also agreed to: expanding the night-time shutdown period to 10pm to 7am if other platforms also commit to do the same. "TikTok's priority has always been fostering a safe and positive space where people can be creative, discover what they love, and connect with their community," a company spokesperson told AFP. "This builds on our commitment and core objective to continually enhance our robust safety tools to protect teens," the spokesperson added. More than a dozen other states, including California and New York, still have suits against TikTok. Read more of this story at Slashdot.

  • Data Center Developer Offers $10,000 Checks To Nearby Households
    by BeauHD on 28/09/2026 at 8:00 pm

    An anonymous reader quotes a report from Tom's Hardware: NorthPoint Development wants to build a data center on 1,300 acres in the Pocono foothills, near Hazle Township, Pennsylvania. As well as seeking to charm the local government with various funding packages, it has proposed paying checks of $10,000 per household. Despite the Pennsylvania town's median income of $60,000, the offer isn't being warmly welcomed by locals, reports the Wall Street Journal. Those interviewed were widely against the data center development plans and cited several reasons for being averse to accepting the payout. The major concerns regarded potential impacts on property values, the specter of noise pollution, and a distrust of both the AI moguls and local government representatives. Offer letters began to be received by Hazle Township back in June. The WSJ recently talked to several residents about NorthPoint's $10,000 offer. While some say the $10,000 would be handy, it couldn't find many residents who were "eager to welcome the data center for the payout," in the journal's words. [...] Traditionally, developers have offered towns and cities packages worth tens of millions, including funding for local services. But direct cash payments to residents represent a new phase of their charm offensive, the WSJ indicates. Perhaps the idea for the direct payments to residents came after "a raucous public meeting last year, where angry locals asked what they had to gain by supporting the data center," ponders the source. The locals won't just get the direct payout, though. Other funds up to $120 million over the next 15 years have been dangled like a carrot for community and local services investments -- improved schools, emergency services, and so on. Meanwhile, Hazle Township's government already rejected the data center project on zoning grounds last year, and it has enacted a temporary moratorium on data center construction. Finally, the $10,000 offer to households is simply not enough in many interviewed folks' opinions. Residents could feel insulted by it, regarding the offer as a bribe, concludes the WSJ report.

  • Meta Taps MongoDB CEO Desai to Drive Enterprise AI Push
    by BeauHD on 28/09/2026 at 7:00 pm

    Meta has hired MongoDB CEO Chirantan "CJ" Desai to lead a new enterprise AI business aimed at turning Meta's models, agents and tools into products companies can deploy themselves. Reuters reports: Desai, a veteran technology executive, took over the role from Dev Ittycheria. MongoDB has appointed Ittycheria as interim CEO as it searches for a permanent replacement. "While the departure is disappointing, we believe MongoDB remains well-positioned strategically and view the share-price reaction as overdone," brokerage Piper Sandler said in a note. [...] Desai will directly report to Meta CEO Mark Zuckerberg in the newly created role of chief enterprise platform officer and will focus on turning the company's AI stack into products and services that companies can deploy for their own businesses. Before joining MongoDB, Desai led product and engineering at Cloudflare and spent nearly eight years at ServiceNow, including as president and chief operating officer.

  • Nvidia Unveils AI Agent Safety Platform With Hardware-Based Watchdog
    by BeauHD on 28/09/2026 at 6:00 pm

    wiredmikey shares a report from SecurityWeek: Nvidia on Monday announced the Open Agent Safety Platform, which combines open source software and a reference system design to keep AI agents within set boundaries from testing through deployment. The chipmaker explained that the platform pairs the open-source OpenShell runtime with Sentry, an out-of-band watchdog running on BlueField-4 DPUs. Nvidia says Sentry can monitor agent activity independently and quarantine an agent that crosses its boundaries within milliseconds. Nvidia is pitching the platform against a backdrop of recent incidents in which frontier AI labs have reported agents escaping the evaluation environments meant to contain them, reaching systems they should not have accessed and, in some cases, misreporting what they did. OpenShell and related skills are available via Nvidia's developer resources page and on GitHub. Read more of this story at Slashdot.
