  • How the US Nuclear Plant Fleet Is Leaning Into AI
    by EditorDavid on 12/10/2026 at 7:22 am

    "This year, nearly the entire fleet of 94 U.S. nuclear reactors has been offered the chance to integrate AI into its operations, and most have taken it," reports IEEE Spectrum: In August, California-based Atomic Canyon launched NIVA, the Nuclear Industry Virtual Assistant, which was developed in cooperation with nuclear-industry groups. The assistant was pilot-tested in nuclear plants run by Constellation Energy and is now available to the United States' entire fleet of reactors.... Meanwhile, the AI-for-nuclear startup Nuclearn says its products have gone to work with more than 65 U.S. partners, a total that includes many traditional plants but also an integration with NuScale Power Corp. that is working toward advanced small nuclear reactors. Microsoft and Nvidia have collaborated on a project to apply AI toward optimizing "the entire life cycle of a nuclear plant, spanning site permitting, design, construction, and continuous operations." The reason for the rapid adoption, according to Nuclearn CFO and cofounder Jerrold Vincent, is twofold. First, the technology companies banking their futures on AI are also keen on a revival of nuclear power to provide the electricity for all those data centers. Vincent says AI is also ideal for addressing some of the nuclear industry's most pressing problems. Many of the things that make reactors so difficult to operate — intricate regulations, along with complex systems for management and maintenance — are exactly the kinds of tasks that AI is good at. The industry is staggering to deal with aging hardware and an aging workforce. If it is going to survive, and have a real shot at a nuclear revival, it will need help from machine intelligence, Vincent says... Right now, the principal output of a nuclear reactor (aside from electricity) is paperwork. Nuclear plants produce piles of documentation to demonstrate regulatory compliance and to record how they respond to any potential problem, from a crack in the sidewalk to a fault in the reactor... Nuclearn's AI products help plants search through large repositories of data more efficiently to more quickly file paperwork with the federal government or figure out how a particular problem was solved in the past. "If you think of it as ChatGPT for nuclear," he says, "it's actually not a bad place to start." It's especially important because the nuclear power industry "has a remarkably skilled but quickly shrinking workforce tasked with keeping old reactors online and possibly starting up new ones to meet surging demand for electricity," the article points out. It also stresses that "So far, both the Nuclearn and NIVA large language models used in the nuclear world report to humans and don't go anywhere near power plant operations."

  • Let's Encrypt to Cut SSL Certificate Lifetimes to 64 Days in February 2027
    by EditorDavid on 12/10/2026 at 3:09 am

    Let's Encrypt "will shorten the default validity period of its TLS certificates from 90 days to 64 days, starting February 10, 2027," reports the blog Linuxiac: All certificates issued or renewed from that date will have a 64-day lifespan unless users explicitly select one of the shorter options already available: 45 or six days. Existing certificates will remain valid until their expiration dates. Let's Encrypt expects the final 90-day certificate to expire on May 11, 2027. The organization also confirmed no valid certificates will be revoked during the transition. To help administrators prepare, Let's Encrypt will introduce 64-day certificates in its staging environment on October 14, 2026, allowing users to test their renewal setups before the change reaches production. The move is part of a broader effort to improve web security by reducing how long compromised or incorrectly issued certificates remain usable... Looking further ahead, the organization plans to reduce the default certificate lifetime again, this time to 45 days in 2028. That makes the upcoming 64-day limit an intermediate step rather than the final destination. "Administrators using cron jobs or scripts with hardcoded renewal intervals should review their configurations," the article suggests. "Another upcoming change concerns domain validation. Let's Encrypt will reduce the period during which a previously completed domain authorization can be reused from 30 days to 10 days. In 2028, that period will shrink further to just seven hours."

  • Game Console Market Craters: Xbox and PS5 Sales Plummet Over 25%
    by EditorDavid on 12/10/2026 at 1:09 am

    "Video game console sales in the U.S. have cratered," reports Tom's Hardware, with sales through August far below where they'd been in 2025: Mat Piscatella, the video game industry advisor at research firm Circana, shared the numbers on his Bluesky account — PlayStation 5 sales have dropped by 25%, putting it at its lowest point since 2013, when gamers held off buying PlayStation consoles in anticipation of the arrival of the PS4, while Xbox's retail figures have cratered by 33% YTD, putting its sales numbers at an all-time low since its launch almost 25 years ago. Piscatella said price sensitivity is becoming a real problem among gamers, especially as the chip shortage has pushed console manufacturers to raise prices. Microsoft has raised the price of the Xbox three times in the past two years, with the 512GB versions jumping by $100 and 1TB models becoming $150 more expensive. Worse, the company has killed off the 2TB model. This brought the Xbox Series S to $499.99 (512GB) and $599.99 (1TB), while the Xbox Series X now costs $749.99 for the Digital Edition, and the disc version costs $50 more at $799.99. PlayStation fans haven't escaped these price hikes, as Sony raised prices for that console by $100 to $150. The base Digital Edition PS5 now costs $599.99, while the version with an optical drive is priced at $649.99. If you want the PS5 Pro, you'll have to shell out $899.99, while those who want to stream games from their console via the PlayStation Portal must now pay $249.99 — $50 higher than its $199.99 launch price. Even used consoles didn't escape inflation, with Sony bumping the price of refurbished PS5 Slim consoles by $100, bringing them to $399. "Still, Piscatella says the U.S. hardware market has never been more precarious since the early 1980s." Read more of this story at Slashdot.

  • Research Firm Calls Anthropic's Upcoming IPO 'Unprecedented Test of Investor Gullibity'
    by EditorDavid on 11/10/2026 at 11:58 pm

    CNBC reports: As Anthropic barrels toward a potential $2 trillion market cap on the Nasdaq, one research firm is valuing the artificial intelligence company at a mere $150 billion and says Wall Street is about to face an "unprecedented test of investor gullibility." In a report on Tuesday, independent financial research provider New Constructs called Anthropic's upcoming offering the "most ridiculous IPO of 2026." To reach its desired valuation, the firm estimates Anthropic would need to record double the trailing year of profit for Nvidia, the world's most valuable tech company. Nvidia's net income over the past four quarters topped $190 billion. Meanwhile, Anthropic's revenue in 2025 was $4.6 billion as the company racked up a net loss of $42 billion, according to Reuters, which cited a leaked copy of the company's prospectus. Anthropic's mounting operating losses coupled with emerging competition from a plethora of open-source models led New Constructs to conclude that, "We don't think Anthropic has a viable business...." Anthropic didn't respond to a request for comment... The New Constructs report also notes that Anthropic's assertion that AI could pose "a catastrophic or existential risk to humanity" is another reason why investors should avoid the IPO. Reuters reported that Anthropic's IPO prospectus "highlights risks associated with its AI models, which it said could exhibit 'self-preserving behaviors,' including attempts to 'resist shutdown,' to 'conceal or manipulate information' and behavior 'resembling blackmail.'" Now Bloomberg writes that "investors considering Anthropic's planned mega-IPO are grappling with an unusual, and more than a little scary, conundrum: How to value a company that some fear could help wipe out the human race?" Anthropic's valuation also drew some scrutiny from a senior analyst at PitchBook. "A $2 trillion price is about 435 times 2025 revenue, less than 44 times the annualized second-quarter revenue of more than $46 billion and just under 31 times the July run rate."

  • Gas Cars Fall Below 50% of Global New Car Sales for the First Time
    by EditorDavid on 11/10/2026 at 9:10 pm

    "Gas cars are now a minority of the world's new car sales," reports Electrek. Gasoline-only vehicles made up 49% of global new-vehicle sales in the first half of 2026, down from 73% in 2021, according to Mobility Global data first reported by Nikkei. It's the first time on record that they've been under half. But there's a catch: most of the cars taking their place still have a gas tank... [The share of gas-only vehicles] fell three points in a single year, from 52% to 49%. Battery-electric vehicles grew 12% to 6.87 million units and took 17% of the market, up three points. Conventional hybrids grew 10% to 7.27 million units, or 18%... [T]he rest is diesel, plug-in hybrids and a few minor fuels. Nikkei ties the acceleration to oil. Fuel prices spiked with the conflict in the Middle East, and buyers went looking for lower running costs. The whole car market shrank about 5% in the first half, according to the IEA, so gas-only sales fell twice as fast as the market. Gas car sales dropped the most in China, down 26%, followed by Europe at 13%... Mobility Global has battery-electric sales up 32% in Europe to 1.81 million, up 81% in Southeast Asia to 350,000, and more than doubling in Oceania to 110,000... Yoshiaki Kawano, an associate director at Mobility Global, told Nikkei that few EV buyers go back to gasoline cars or hybrids. He expects demand based on "genuine consumer needs rather than subsidies" to grow as prices come down... [Hybrids] outsold battery-electric vehicles in the first half, 7.27 million to 6.87 million... Only the 17% that's battery-electric burns no fuel at all. So about 83% of the new vehicles sold in the world this year still came with an engine. The article notes that U.S. hybrid sales were up 23%, reaching a record 16.3% of vehicles sold in the second quarter of 2026, while the share of ICE vehicles went down. Gas-only cars went from 73% to 49% of the market in less than five years, and nothing in the data suggests they're getting that share back. The last time gasoline wasn't on top was the early 1900s, when steam and electric cars outsold it in the US. I hate seeing media headlines claiming that "EV sales are down" and that "EV growth has stalled." The data is clear: that's true in the US, but only in the US. The rest of the world is moving to electric vehicles, and it is not slowing down. Read more of this story at Slashdot.

  • 'The Social Reckoning' Bombs with $5.5 Million Opening
    by EditorDavid on 11/10/2026 at 8:10 pm

    Why didn't The Social Reckoning enjoy the box office success of 2010's The Social Network, asks IndieWire/A>: [T]here wasn't the same urgency in the story being told. The Social Reckoning focuses less on Zuckerberg, and more on data engineer Frances Haugen's decision to blow the whistle on how Facebook's algorithms were promoting political content that radicalized users, as well as the company's awareness of how its products were contributing to a rise in bullying and teen suicide... [B]ut The Social Reckoning arrives as a much greater threat has emerged from Silicon Valley. Artificial intelligence is dominating the headlines, as fears mount about the economic disruptions it will unleash when millions of jobs are replaced by machines, and, graver still, its potential to trigger a world-ending event... And it's not like Haugen's testimony led to lasting change at Facebook... As IndieWire's Ryan Lattanzio put it, "'The Social Reckoning' argues that the aftermath of their whistleblowing is still somehow felt today. In actuality, living as we do in 2026, it pretty much feels like... no one cared, and nothing changed?" After the first movie's director bowed out, Sony Pictures shied away from selling it as a sequel — but the problems run deeper, the article adds. "The Social Reckoning isn't just a financial failure, it's a critical one, too. The reviews were blistering..." Although on the bright side, "Sony wisely kept The Social Reckoning's budget at $30 million, meaning it won't face losses on the scale of a Digger... " Variety writes that Digger "cratered in its second weekend with $3.2 million from 3,321 theaters, a 60% decline from its dismal $8 million debut. So far, the Tom Cruise satire has limped to $14 million domestically and $35.3 million globally. Warner Bros. spent above $160 million to produce the film, which is shaping up to be one of the biggest bombs ever..." Read more of this story at Slashdot.
