  • Coal Power Generation Falls in China and India for First Time Since 1970s
    by msmash on 14/01/2026 at 6:10 pm

    Coal power generation fell in China and India for the first time since the 1970s last year, in a "historic" moment that could bring a decline in global emissions, according to analysis. From a report: The simultaneous fall in coal-powered electricity in the world's biggest coal-consuming countries had not happened since 1973, according to analysts at the Centre for Research on Energy and Clean Air, and was driven by a record roll-out of clean energy projects. The research, commissioned by the climate news website Carbon Brief, found that electricity generated by coal plants fell by 1.6% in China and by 3% in India last year, after the boom in clean energy across both countries was more than enough to meet their rising demand for energy. China added more than 300GW of solar power and 100GW of wind power last year -- together, more than five times the UK's total existing power generation capacity -- which are both "clear new records for China and, therefore, for any country ever," the report said. India added 35GW of solar, 6GW of wind and 3.5GW of hydropower last year, according to the analysis. Read more of this story at Slashdot.

  • McKinsey Asks Graduates To Use AI Chatbot in Recruitment Process
    by msmash on 14/01/2026 at 5:30 pm

    McKinsey is asking graduate applicants to "collaborate" with an AI tool as part of its recruitment process, as competence with the technology becomes a requirement in competing for top-level jobs. From a report: The blue-chip consultancy is incorporating an "AI interview" into some final-round interviews, according to CaseBasix, a US company that helps candidates apply for posts at leading strategic consulting companies. In an online post, CaseBasix said candidates in "select final rounds" in the US have been asked to complete tests using McKinsey's internal AI tool, Lilli. They are required to carry out practical consulting tasks with the help of Lilli. "In the McKinsey AI interview, you are expected to prompt the AI, review its output, and apply judgment to produce a clear and structured response. The focus is on collaboration and reasoning rather than technical AI expertise," CaseBasix said. Read more of this story at Slashdot.

  • Bezos's Vision of Rented Cloud PCs Looks Less Far-Fetched
    by msmash on 14/01/2026 at 4:55 pm

    Amazon founder Jeff Bezos once told an audience that he views local PC hardware the same way he views a 100-year-old electric generator he saw in a brewery museum -- as a relic of a pre-grid era, destined to be replaced by centralized utilities that users simply rent rather than own. The anecdote, shared at a talk a few years ago, positioned Amazon Web Services and Microsoft Azure as the inevitable successors to the desktop tower. Bezos argued that users would eventually abandon local computing for cloud-based solutions, much as businesses once abandoned on-site power generation for the electrical grid. Current market dynamics have made that prediction feel more plausible. DRAM prices have become increasingly untenable for consumers, and companies like Dell and ASUS have signaled price increases across their PC ranges. Micron has shut down its consumer DRAM operations entirely, prioritizing AI datacenter demand instead. SSD storage is expected to face similar constraints. Cloud gaming services from Amazon Luna, NVIDIA GeForce Now and Xbox are seeing steady growth. Microsoft previously developed a consumer version of its business-grade Windows 365 cloud PC product, though the company deprioritized it -- the economics didn't work when cheap laptops remained available. That calculus could shift. Xbox Game Pass's 1440p cloud gaming runs $30 monthly and NVIDIA recently imposed a 100-hour cap on its cloud platform. The infrastructure remains expensive to operate, but rising local hardware costs may eventually close that gap. Read more of this story at Slashdot.

  • Matthew McConaughey Trademarks Himself To Fight AI Misuse
    by msmash on 14/01/2026 at 4:02 pm

    Matthew McConaughey is taking a novel legal approach to combat unauthorized AI fakes: trademarking himself. From a report: Over the past several months, the "Interstellar" and "Magic Mike" star has had eight trademark applications approved by the U.S. Patent and Trademark Office featuring him staring, smiling and talking. His attorneys said the trademarks are meant to stop AI apps or users from simulating McConaughey's voice or likeness without permission -- an increasingly common concern of performers. The trademarks include a seven-second clip of the Oscar-winner standing on a porch, a three-second clip of him sitting in front of a Christmas tree, and audio of him saying "Alright, alright, alright," his famous line from the 1993 movie "Dazed and Confused," according to the approved applications. "My team and I want to know that when my voice or likeness is ever used, it's because I approved and signed off on it," the actor said in an email. "We want to create a clear perimeter around ownership with consent and attribution the norm in an AI world." Read more of this story at Slashdot.

  • UK Police Blame Microsoft Copilot for Intelligence Mistake
    by msmash on 14/01/2026 at 3:20 pm

    The chief constable of one of Britain's largest police forces has admitted that Microsoft's Copilot AI assistant made a mistake in a football (soccer) intelligence report. From a report: The report, which led to Israeli football fans being banned from a match last year, included a nonexistent match between West Ham and Maccabi Tel Aviv. Copilot hallucinated the game and West Midlands Police included the error in its intelligence report without fact checking it. "On Friday afternoon I became aware that the erroneous result concerning the West Ham v Maccabi Tel Aviv match arose as result of a use of Microsoft Co Pilot [sic]," says Craig Guildford, chief constable of West Midlands Police, in a letter to the Home Affairs Committee earlier this week. Guildford previously denied in December that the West Midlands Police had used AI to prepare the report, blaming "social media scraping" for the error. Read more of this story at Slashdot.

  • Europe is Rediscovering the Virtues of Cash
    by msmash on 14/01/2026 at 2:40 pm

    After spending years pushing digital payments to combat tax evasion and money laundering, European Union ministers decided in December to ban businesses from refusing cash. The reversal comes as 12% of European businesses flatly refused cash in 2024, up from 4% three years earlier. Over one in three cinemas in the Netherlands no longer accept notes and coins. Cash usage across the euro area dropped from 79% of in-person transactions in 2016 to just 52% in 2024. Sweden leads the digital shift where 90% of purchases now happen digitally and cash represents under 1% of GDP compared to 22% in Japan. The policy change stems from concerns about financial inclusion for elderly and poor populations who struggle with digital systems. Resilience worries also drove the decision after Spaniards facing nationwide power cuts last spring found themselves unable to buy food. European officials worry about dependence on American payment giants Visa and MasterCard. The EU now recommends citizens store enough cash to survive a week without electricity or internet access.
