  • eBay Rejects GameStop's $56 Billion Takeover As 'Neither Credible Nor Attractive'
    by BeauHD on 12/05/2026 at 5:00 pm

    An anonymous reader quotes a report from Reuters: EBay on Tuesday rejected a $56 billion takeover bid from the much smaller GameStop over financing doubts, calling the proposal "neither credible nor attractive." EBay, which has roughly four times GameStop's market value, also underscored that its turnaround efforts under CEO Jamie Iannone have boosted growth, with its stock returning 201% since Iannone took the position six years ago. "We have concluded that your proposal is neither credible nor attractive," eBay Chairman Paul Pressler said in a statement. "eBay's Board is confident the company, under its current management team, is well-positioned to continue to drive sustainable growth." He also pointed to concerns with GameStop's bid, including its financing, its impact on eBay's long-term growth and the leadership structure of a potentially combined company. Last week, GameStop's CEO Ryan Cohen delivered one of the most memorable CNBC interviews in recent memory... initially disinterested, then increasingly hostile, with little eye contact, few real answers to basic questions, and repeated robotic deflections to "check the website." It's worth a watch if you have a few extra minutes. Read more of this story at Slashdot.

  • FCC Says Foreign-Made Routers Can Get Updates Until 2029
    by BeauHD on 12/05/2026 at 4:00 pm

    The FCC has softened its ban on foreign-made consumer routers, allowing vendors to keep issuing broader software and firmware updates for devices already in use in the U.S. through at least January 2029. Dark Reading reports: Under the original FCC ruling, foreign manufacturers were permitted to provide only limited maintenance and security patches to US customers through March 2027. In a public note (PDF) on May 8, the FCC extended that deadline to at least January 2029 and also expanded the scope of permissible updates. The FCC will now allow foreign manufacturers to provide not just minor security fixes and changes, but also more major software and firmware updates that could affect router functionality, which previously required additional FCC review. The agency described the revisions as intended to ensure the continued safety of already deployed foreign-made consumer routers in the US. "The FCC likely issued this revision in response to the operational realities of network security and the slow pace of equipment replacement," says Jason Soroko, senior fellow at Sectigo. "Replacing millions of embedded devices across national infrastructure requires immense time and capital, and abandoning existing systems to a completely unpatched state would create an immediate vulnerability." "This waiver significantly alleviates the most pressing fears tied to the initial ban by preventing a sudden and dangerous security vacuum," added Soroko. Read more of this story at Slashdot.

  • First Real-Time Brain-Controlled Hearing Device
    by BeauHD on 12/05/2026 at 3:00 pm

    Researchers at Columbia demonstrated the first real-time brain-controlled hearing system that can identify which speaker a listener is focusing on in a noisy environment and automatically amplify that voice while suppressing others. "This breakthrough addresses the 'cocktail party effect,' a major limitation of conventional hearing aids, which often struggle to distinguish between overlapping conversations in noisy settings," reports Neuroscience News. From the report: In the new study, Columbia researchers teamed up with surgeons and their epilepsy patients who were undergoing brain surgery to better pinpoint the sources of their seizures. The hospital patients, who volunteered to be part of this study, already had electrodes implanted in their brains. [senior author Nima Mesgarani's] system used the electrodes to measure the brain activity of the patients as they focused on one of two overlapping conversations played simultaneously. The system then automatically detected which conversation a patient was paying attention to and adjusted the volume in real time, turning up that conversation while quieting the other. For one volunteer, the experience of controlling the system with her brain was literally unbelievable. She accused the researchers of secretly adjusting the volumes. Others told stories about friends and family with hearing impairments who could benefit from such a technology. One person said: "It seems like science fiction." [...] The scientists developed real-time machine-learning algorithms that could examine the brainwaves and identify which conversation the patients were paying attention to. Once deployed, their system could rapidly deduce which conversation each listener was paying attention to and make it easier for them to hear it. This happened both when the researchers guided the subjects toward a particular conversation, and when the subjects chose freely, as would be necessary in a real-world conversation. "For this to work in real time, the system has to be very fast, accurate and stable for the experience to feel pleasant for the listener," Dr. Mesgarani said. The scientists found their new system correctly identified which conversation the volunteers paid attention to. This dramatically improved the intelligibility of the speech the volunteers focused on, reduced listening effort, and was consistently preferred by the volunteers when compared to conversations the system did not provide assistance with. One volunteer recalled her uncle, who had hearing problems. "Can you imagine if this technology existed in a world [where] ... he could access it? He might actually live a much more peaceful... life." The research has been published in Nature Neuroscience. Read more of this story at Slashdot.

  • Arts and Cultural Engagement 'Linked To Slower Pace of Biological Aging'
    by BeauHD on 12/05/2026 at 11:00 am

    An anonymous reader quotes a report from the Guardian: Singing, painting or visiting a gallery or museum helps people age more slowly, according to the latest study to link taking an active interest in art and culture with improved health. The findings are the first to show that both participating in arts activities and attending events, such as viewing an exhibition, lead to people staying biologically younger. "These results demonstrate the health impact of the arts at a biological level. They provide evidence for arts and cultural engagement to be recognized as a health-promoting behavior in a similar way to exercise," said Prof Daisy Fancourt, the lead author of the research and the head of the social biobehavioral research group at University College London. However, slower aging does not necessarily mean someone will live longer. The "epigenetic clocks" used in the study to assess biological ageing are predictive of future morbidity and mortality, and previous studies have suggested a link between arts engagement and longer lifespan, but much more research would be needed to establish potential causal effects on longevity. Those who take part in artistic pursuits the most often slow the pace of their biological aging the most. Under one of the study's methods of assessment, those who did so at least weekly slowed their aging process by 4%, while monthly engagement led to it slowing by 3%. Similarly, another of the tests showed that those who undertook an arts activity at least once a week were on average a year younger biologically than those who rarely engaged in such pursuits. Those who exercised once a week were only six months younger by that measure. The benefit the arts confer on the pace at which people age is so dramatic that it is comparable to the difference between smokers and those who have given up smoking, the researchers say. The results, published in the journal Innovation in Aging, are based on blood test and survey response data from 3,556 adults taking part in the UK Household Longitudinal Study. It uses blood samples to estimate people's biological age and the pace at which they are ageing. Read more of this story at Slashdot.

  • Microsoft CEO Satya Nadella Testifies In OpenAI Trial
    by BeauHD on 12/05/2026 at 7:00 am

    The Musk v. Altman trial entered its third week Monday, with Microsoft CEO Satya Nadella and former OpenAI co-founder and renowned AI researcher Ilya Sutskever taking the stand. Nadella testified that Elon Musk never raised concerns to him that Microsoft's investments in OpenAI violated any special commitments, and said he viewed the partnership as clearly commercial from the start. He also described OpenAI's 2023 board crisis as "amateur city." Meanwhile, Sutskever testified that he had raised concerns about Sam Altman because he feared OpenAI could be "destroyed." He expressed concerns about Altman's behavior to the board, in part because he said he felt "a great deal of ownership" over the startup. "I simply cared for it, and I didn't want it to be destroyed," Sutskever said. CNBC reports: Nadella said he was "very proud" that Microsoft took the risk to invest in OpenAI when "no one else was willing" to bet on the fledgling lab. Musk, who testified late last month, said Microsoft's $10 billion investment was the key tipping point that made him believe OpenAI was violating its nonprofit mission. He testified that the scale of the investment bothered him, and it prompted him to open a legal investigation into OpenAI. "I was concerned they were really trying to steal the charity," Musk said from the stand. Nadella said he did not believe Microsoft's investments in OpenAI were donations, and that there was a clear commercial element to their partnership from the outset. He said during the partnership's early years, Microsoft gave OpenAI sharp discounts on computing resources, and Microsoft believed it would reap marketing benefits from doing so. During a separate video deposition that was played on Monday morning, Michael Wetter, a corporate development executive at Microsoft, said the company has recognized approximately $9.5 billion in revenue to date through its partnership with OpenAI as of March 2025. [...] Nadella said he was "pretty surprised" by the board's decision [to fire Altman in November 2023], and that his priority was to try and figure out how to maintain continuity for Microsoft customers. Immediately after Altman was removed, Nadella said he made an effort to learn more about what happened, adding that he suspected jealousy and poor communication was at play. During conversations with OpenAI board members after the firing, Nadella said he was simply trying to understand the language in the OpenAI's statement about Altman being "not consistently candid" while communicating with the board. That language, Nadella said, "just didn't sort of suffice, because this is the CEO of a company that we are invested in and we're deeply partnered with, and so I felt that they could have explained to me what are the incidents or what is the detail behind it." There must have been instances of jealousy or miscommunication that could have justified pushing out Altman, Nadella said. He wanted more depth from the board members after the remark about candor, but no such information was available, he said. "It was sort of amateur city, as far as I'm concerned," Nadella testified. [...] Musk testified that he is not entirely against OpenAI having a for-profit unit, but he said it became "the tail wagging the dog." He repeatedly accused Altman and Brockman of enriching themselves from a charity while also reaping the positive associations that come from running a nonprofit. "Microsoft has their own motivations, and that would be different from the motivations of the charity," Musk said from the stand. "All due respect to Microsoft, do you really want Microsoft controlling digital superintelligence?" During a videotaped deposition shown in court last week, former OpenAI director Tasha McCauley recalled a discussion with Nadella and her fellow board members after the 2023 decision to dismiss Altman as OpenAI's CEO. "To the best of my recollection, Satya wanted to restore things to as they had been," McCauley said. The board members didn't think that was the right move, she said. But as a court witness on Monday, Nadella said he never demanded that the board reinstate Altman as OpenAI CEO.

  • A Data Center Drained 30 Million Gallons of Water Unnoticed
    by BeauHD on 12/05/2026 at 3:30 am

    A Georgia data center developed by QTS used nearly 30 million gallons of water through two unaccounted-for connections before residents complained about low water pressure and the county utility discovered the issue. "All told, the developer, Quality Technology Services, owed nearly $150,000 for using more than 29 million gallons of unaccounted-for water," reports Politico. "That is equivalent to 44 Olympic-size swimming pools and far exceeds the peak limit agreed to during the data center planning process." From the report: The details were revealed in a May 15, 2025 letter from the Fayette County water system to Quality Technology Services, which outlined the retroactive charge of $147,474. The letter did not specify how many months the unpaid bill covered, but when asked about it Wednesday, Vanessa Tigert, the Fayette County water system director, said it was likely about four months. A QTS spokesperson said the timeframe was 9-15 months. Once the data center was notified, it paid all retroactive charges, a QTS spokesperson said in an email, noting the unmetered water consumption occurred while the county converted its system to smart meters. The Fayette County water system confirmed the data center's meters are now fully integrated and tracked. Tigert, the water system director, blamed the issue on a procedural mix-up. "Fayette County is a suburb, it's mostly residential, and we don't have much commercial meters in our system anyway," she said. "And so we didn't realize our connection point wasn't working." The incident became public last week when a county resident obtained the 2025 letter to QTS through a public records request and posted it on Facebook, prompting outrage from residents concerned about the data center's water consumption. [...] Tigert, who sent the 2025 letter to QTS, said the utility didn't know about the water hookups because the connection process "got mixed up" as the county transitioned to a cloud-based system while also trying to accommodate an industrial customer. Tigert also said her staff is small and at capacity. "Just like any water system, we don't have enough staff. We can't keep staff," she said. "I've got one person that's doing inspections and plan review, and so he's spread pretty thin." She said it's possible her staff did know about hookups but that she hadn't been able to locate the inspection report. "I may have hit 'send' too soon," she said about the 2025 letter to QTS. While the utility charged the data center a higher construction rate for the unapproved water consumption, Tigert confirmed the utility did not penalize or fine the data center. For what it's worth, the Blackstone-owned company says its data centers use a closed-loop cooling system that does not consume water for cooling. The reason for last year's high water use, according to QTS, was the temporary construction work such as concrete, dust control, and site preparation. Once the campus is fully operational, it should only use a small amount of water for things like bathrooms and kitchens. But that point could still be years away, as construction and expansion in Fayetteville may continue for another three to five years. Read more of this story at Slashdot.
