  • 'Off the Charts' El Nino Is Already the Strongest Since Records Began
    by BeauHD on 22/08/2026 at 7:00 am

    A rapidly developing El Nino is already reaching record-setting levels for this time of year and is expected to intensify further over the coming months. "The El Nino has blossomed. It is off the charts. Usual measures of El Nino have blown past prior record levels in the period with good data, even though maximum effects are still several months in the future," writes renowned climate scientist James Hansen at Columbia University in New York in a newsletter sent today. Climate scientists disagree over whether it has already surpassed previous "super El Nino" events on every metric, but several say the signal is unprecedented in forecasts and could ultimately become the strongest modern event on record. New Scientist reports: There are different ways of measuring El Ninos, which occur when warm surface waters spread eastwards along the equator across the surface of the tropical Pacific Ocean. Hansen thinks the best measure is how much warmer than usual the upper 300 meters of the eastern tropical Pacific becomes. "Our preferred metric, the heat anomaly in the upper 300 meters of the Equatorial Pacific Ocean... already exceeds the 1997-98 super El Nino," he writes. [...] What's clear is that this developing super El Nino will soon exceed previous events on all measures. "I have never seen an El Nino signal this intense in our forecasts," [Adam Scaife at the Met Office, the UK's national weather service] said in a statement released today. "If the forecast is accurate... then 2026 will far exceed our recent experience of El Nino and its worldwide climate influences." While Hansen is comparing the developing super El Nino to other modern events for which we have direct temperature records, Hayley Fowler at Newcastle University in the UK thinks it could also exceed historical events suspected to be even larger. "The super El Nino evolving in the Pacific will likely be the biggest ever recorded, reaching or exceeding the levels of the 1877-1878 El Nino which caused widespread impacts, including famines and around 50 million deaths (3-4 percent of the global population at the time), mostly across Asia and South America," Fowler said in a statement.

  • China Joins Europe In Scrapping Windows For Linux
    by BeauHD on 22/08/2026 at 3:30 am

    An anonymous reader quotes a report from ZDNet: According to a Bloomberg report, attributed to China's Ministry of State Security, the country has ordered some government agencies to drop Windows 10 China Government Edition for Chinese-made Linux distributions. Why not Windows 11? Because China, like many other non-US governments, no longer trusts American companies with their software and services. This approach is all about digital sovereignty. In addition, even before the recent trend of governments outside America moving away from Windows, Beijing has started a long-running push to replace foreign technology in sensitive systems with domestic, open-source alternatives. [...] The Chinese government did not specify which Linux versions would replace Windows 10. However, the stock prices of Chinese Linux suppliers, Kylin Software and Tongxin Software Technology (commonly known as UnionTech), immediately jumped. These companies' respective operating systems, Kylin OS (no relation to Ubuntu Kylin) and UnionTech OS (UOS), were already positioned as domestic desktop and server replacements for Windows in government, state-owned enterprise, and critical-infrastructure environments. [...] Huawei's HarmonyOS 2, which began as an Android variant but is now a proprietary mobile and Internet of Things (IoT) operating system, is also being developed into a PC platform. HarmonyOS 2 won't be deployed anytime soon. Kylin and UOS are the only mature desktops that are ready for institutional desktop deployments. [...] ... this transition won't be easy. For agencies now moving off the government Windows build, the issue will be more demanding than simply swapping one desktop interface for another. Migration requires application testing, peripheral and driver validation, identity system integration, document-format compatibility, staff retraining and, in many cases, replacement or adaptation of Windows-dependent line-of-business software. The report provides no details on exactly how this transformation will occur. But the speed of the shift suggests that these issues are already being addressed in China's centralized managed desktop stack. Read more of this story at Slashdot.

  • Township Fights Nuclear Weapons Data Center By Passing a Moratorium on Electrical Infrastructure
    by BeauHD on 21/08/2026 at 11:00 pm

    Ypsilanti Township, Michigan, has imposed a six-month moratorium on "major electric utility infrastructure" in its latest attempt to delay a proposed $1.2 billion University of Michigan-Los Alamos data center that would support nuclear-weapons research. Township leaders, who have already paused water service for data centers, say the project has moved forward without adequate consultation and want more time to study noise, grid impacts, and other effects on residents. 404 Media reports: Last year, the university announced it was partnering with LANL on the construction of a massive 220,000 square foot hyperscale data center in Ypsilanti Township and residents have been fighting it ever since. During a meeting of the Township Board on August 18, the council unanimously passed a resolution that will delay the construction of new electrical infrastructure for 180 days. Data centers need a lot of energy, and Michigan's power authority will have to build new substations in the Township to power the proposed facility. The moratorium asked the local power authorities to use the six month delay to study noise pollution and how the new infrastructure would affect existing customers. The moratorium is narrowly focused on "the nature and scale of electrical infrastructure necessary to serve new high-energy-demand land uses [...] including infrastructure associated, but not limited to hyper-scale data centers, mid-sized data centers, artificial intelligence computing facilities, and high-performance computational centers, industrial facilities, and other intensive electrical users." Earlier this month, the University of Michigan announced it had settled on a specific plot of land in Ypsilanti Township -- a 144-acre plot on Textile Road. In a press release about the decision, the University said the data center would have the "capacity to change the world" and insisted it would not be a "high value target risk" in a war, that it would not store any hazardous nuclear material, and was not a weapons production facility. LANL previously confirmed that the data center will be used for nuclear weapons research. Ypsilanti Township Supervisor Brenda Stumbo told WEMU news that the selection of the site was a "travesty of justice" because it ignores constituents' concerns about environmental impact. During the August 18 moratorium vote, the Board projected a large stock photograph of an electric substation behind its members. The photo was meant to remind people of the size of the incoming infrastructure and the lack of communication from the university about it. "This picture's really important to think about because U of M has been so crystal clear that they've been communicating to us abundantly -- which is not true," Township clerk Debbie Swanson said during the meeting. "That speaks to the lack of respect." Read more of this story at Slashdot.

  • Apple Cuts Jobs In Siri, Vision Pro Immersive Video and Gaming Teams
    by BeauHD on 21/08/2026 at 10:00 pm

    Apple is cutting more than 200 jobs as it shifts resources toward a rebuilt, AI-powered Siri and other future products. Roughly 100 positions are being eliminated from the Vision Pro organization, including much of its gaming team and some immersive-video staff. Another 100 cuts are hitting the Siri and software teams. Bloomberg reports: In a statement, Apple acknowledged that it was realigning some teams "to evolve our business to deliver the best experiences for our users." "While we will create new roles as part of this change, it will also impact a limited number of existing roles," the company said. "We are grateful to these team members for their contributions, and we are committed to supporting them throughout their transition, including opportunities to apply for other roles at Apple." The Siri reshuffling is tied to an upcoming AI-infused version of the assistant, which is built on a new technical architecture. That shift requires a change in the necessary expertise, prompting the company to eliminate a small number of existing roles, reallocate resources and create new positions supporting the updated Siri. The changes to the Intelligent Systems Experience team reflect an effort to reorganize work on AI-powered capabilities. As more groups bring AI functions to apps, features and services, Apple is realigning teams to match priorities and accelerate development. The restructuring will eliminate some existing positions while creating new roles. Read more of this story at Slashdot.

  • American Who Wiped His Phone With 'Duress' Password During Border Search Gets Felony Charges
    by BeauHD on 21/08/2026 at 9:00 pm

    Federal prosecutors have charged activist Samuel Tunick with obstruction after he gave Customs and Border Protection officers a duress passcode that wiped his GrapheneOS-powered Pixel during a border search. "His prosecution is one of the earliest known instances of the federal authorities charging a person with destroying evidence using a program designed to wipe a device clean after a specific code is entered," reports The New York Times. From the report: "Obstructing federal law enforcement is a serious matter that has serious repercussions," Theodore Hertzberg, the U.S. attorney for the Northern District of Georgia, said in a statement. "Individuals who destroy or attempt to destroy property, including data, to prevent lawful search and seizure should expect to face prosecution and punishment for their actions." A spokeswoman for U.S. Customs and Border Protection said in a statement that the agency had the authority to search the electronic devices of anyone entering or leaving the United States, regardless of citizenship, to enforce laws addressing terrorism, child exploitation, drug- and human-smuggling, visa fraud and national security threats. "The border search will only include an examination of information that is present on the device at the time it is presented for inspection," the spokeswoman said, adding that it searched the electronic devices of fewer than 0.01 percent of all arriving international travelers in the last fiscal year. "Just the knowledge that the government is peering into your private life in this way, trying to dig up dirt on you, even though it's unsuccessful, is creepy," Tunick said, in response to a question about how the charges have affected him. His message: "The government doesn't own our communications, our relationships, as hard as they might try to. We have to defend our fundamental right to privacy; otherwise we can't say that we really live in a democracy." Read more of this story at Slashdot.

  • AI Boosted Homework Scores, Then Exam Scores Dropped
    by BeauHD on 21/08/2026 at 8:00 pm

    An anonymous reader quotes a report from The Economist: Students and school children are increasingly using artificial intelligence. A survey last year by Chegg, an ed-tech firm, found that 80% of rich-world undergraduates used it in their studies. More recent polls put the figure at 94% in Britain and 93% in Germany. Such widespread adoption has fueled concerns about the impact the technology might be having on learning. Teachers report marking identikit essays that they suspect are churned out by ChatGPT. Yet firm evidence on AI's educational effects has been lacking. David Stromberg of Stockholm University and Victor Lei and Wu Yanhui of the University of Hong Kong set out to fill the gap. They tracked 27,000 pupils aged 12-18 in China, where AI adoption has been fast. Around 80% reported using models such as Doubao and DeepSeek; the other 20% formed the control group. The results are eye-opening. After six months, pupils using AI saw their average homework score rise by 18% across all subjects. The time they took to complete each assignment fell from an average of 64 minutes to 45. But come exam time, the same students scored 20% below their classmates who had not called on AI's help. Homework scores once predicted exam performance; now those who score highest are, perversely, more likely to do worse in exams. The takeaway: "AI can boost learning productivity, but only for those who use the technology intelligently," reports The Economist. "Students must resist the temptation to reach for an AI-generated answer before thinking things through for themselves." Read more of this story at Slashdot.
