  • Cloudflare Keeps 1.1.1.1 Out of Piracy Blocking, Escapes Penalties In France
    by BeauHD on 09/10/2026 at 3:00 pm

    An anonymous reader quotes a report from TorrentFreak: Cloudflare doesn't block pirate sports streaming sites through its 1.1.1.1 DNS resolver in France, only through its CDN. The Paris Judicial Court has now accepted that stance, rejecting [French pay-TV provider] Canal+'s request for penalties of 50,000 euros per site, per day. Interestingly, the court's conclusion relies on statistics provided by Canal+ itself. [...] As a result, Cloudflare will not be penalized under these orders, even though its public DNS resolver is not blocking the sites in question. That is in line with the company's long-standing claim that it doesn't interfere with its DNS. In its recent transparency reports, Cloudflare repeatedly stated that it hasn't blocked any content through 1.1.1.1, despite orders from French and Italian courts. "To date, Cloudflare has not blocked content through the 1.1.1.1 Public DNS Resolver," the company's latest report reads. [...] Blocking through the CDN is another matter. According to the same report, Cloudflare geoblocked 1,238 domains in France in the second half of 2025, all under a single court order. In the first half of the year, it geoblocked 662 domains under seven orders. Cloudflare recently explained its position to the European Commission, in a submission (PDF) to its Counterfeit and Piracy Watch List consultation, stressing that global public DNS resolvers should not be used to block or restrict access. Instead, it highlights its real-time pirate stream blocking program, which allows vetted rightsholders to flag pirate streams that run through its network. These streams are disrupted "within seconds," Cloudflare says, without any DNS or IP address blocking. "For live content, where speed is crucial, Cloudflare has built real-time mitigation mechanisms that allow vetted rightsholder partners to flag infringing streams. When those streams are running through our network, we act on them in seconds," Cloudflare informed the Commission. For now, Cloudflare can continue to block pirate sites through its CDN only, while its 1.1.1.1 DNS resolver remains untouched. Canal+ can still appeal the rulings, so it may not be the last we hear of it. Read more of this story at Slashdot.

  • A 1960 Paper Published In Science Predicts World Will End Next Month
    by BeauHD on 09/10/2026 at 11:00 am

    sciencehabit shares a report from Science Magazine: A physicist has put a definite date on Doomsday," The New York Times wrote on November 4, 1960. "He calculates that it will come on Friday the Thirteenth in November, 2026 A. D. On that date, or thereabouts, the human population will have expanded so far as to approach infinity and thus will automatically annihilate itself." The newspaper was right -- but the prediction was wrong. That week, Austrian American physicist Heinz von Foerster and two colleagues published a paper in Science with the stunningly succinct title "Doomsday: Friday, 13 November, A.D. 2026." The work was based on a simple observation: The time it took for the human population to double in size kept getting shorter. Using population estimates from about 400 B.C.E. until 1958 C.E., the authors -- all from the department of electrical engineering at the University of Illinois Urbana-Champaign -- came up with an equation that best described the trend. If things continued the way they were going, the number of humans on Earth would rise faster and faster, reaching more than 25 billion by 2020. The researchers didn't calculate when humanity would run out of food, land, or energy. They just concluded that at some point this year, the equation ceased to give meaningful results because the predicted population shot toward infinity. That was their doomsday. "Our great-great-grandchildren will not starve," they wrote. "They will be squeezed to death." The exact date was somewhat arbitrary, however. The formula solved to 2026.87 plus or minus 5.5 years, and The New York Times reported that von Foerster "searched the center of this doom-time span for an appropriate date and found that a Friday the Thirteenth would fall conveniently in November of 2026." (November 13 also happened to be his birthday.) [...] [D]emographers, annoyed by what they saw as a provocation by outsiders, pointed out obvious flaws. For example, the time it takes for the number of humans to double could get a lot shorter, but certainly not shorter than the 9 months it takes for a baby to develop. "In view of the comments that subsequently were published in this journal, an extensive discussion of this article does not seem to be required," public health expert Harold Dorn drily noted in Science 2 years after von Foerster's article was published. The forecast would set a record, he predicted, "for the short length of time required to demonstrate its unreliability." "The failure of the Doomsday equation is ultimately a cautionary tale about the dangers of extrapolating from historically exceptional circumstances," writes economist Javier Birchenall of the University of California, Santa Barbara writes in a Perspective published in Science today.

  • Apollo Software Pioneer Margaret Hamilton Dies at 90
    by BeauHD on 09/10/2026 at 7:00 am

    "Margaret Hamilton, the groundbreaking researcher who helped create the field of software engineering and whose code helped land NASA's Apollo astronauts on the moon to win the 20th century space race, has died," writes longtime Slashdot reader Veeru. "She was 90." MIT News reports: A computing pioneer who authored over 130 publications, Hamilton helped to establish software engineering as a dedicated discipline. She worked at MIT from 1959 until the mid-1970s, after which she became a successful computing entrepreneur and CEO. Her life's work was recognized with many awards and honors, including the 2016 Presidential Medal of Freedom from President Barack Obama, whose citation noted: "Hamilton defined new forms of software engineering and helped launch an industry that would forever change human history. Her software architecture led to giant leaps for humankind, writing the code that helped America set foot on the moon." "To say Margaret Hamilton was a pioneer -- to say she was ahead of her time -- would be a dramatic understatement. She was a software engineer at a time when that field was in its infancy, and she not only developed advanced code herself but also led a team in using that nascent technology to develop one of the most complex systems humanity had ever achieved," says Olivier de Weck, the Apollo Program Professor and interim head of the MIT Department Aeronautics and Astronautics. "The Apollo program still stands as one of our greatest testaments to the power of collaboration, ingenuity, and engineering, and Margaret Hamilton was a fundamental contributor to that program's success. And for her that was just the beginning! She went on to become an entrepreneur and remained on the cutting edge of systems software throughout an extraordinary career, while acting as an advocate, mentor, and inspiration to millions."

  • First Thorium Nuclear Clocks Begin to Tick
    by BeauHD on 09/10/2026 at 3:00 am

    Researchers in Vienna and Beijing have independently built the first nuclear clocks based on oscillations inside thorium nuclei, marking a major milestone for a field that could eventually produce highly portable, ultra-precise timekeepers. The clocks are already precise enough to lose only about a second over millions of years. The New York Times reports: The first nuclear clocks are not going to immediately supplant the worldwide network of atomic clocks, whose steady ticking we rely on for GPS and the definition of a second. Nor have they captured the record for most precise timepiece; the best atomic clocks are about 10,000 times more reliable and would take more than 100 billion years to lose one second. But nuclear clocks hold a bevy of potential advantages over existing atomic clocks. One day, they could be more reliable than the leading atomic versions, and nuclear clocks could be made more portable. They even hold the ability to search for certain kinds of dark matter -- the invisible stuff whose clumps make up 83 percent of the matter in the universe. If a particle of dark matter passed through the thorium nuclei, it could register as a wobble in the nuclear clock's otherwise steady ticktock. The findings have been published in the journal Nature.

  • US Bars Microsoft, Adobe, and Major IT Firms From Green Card Program
    by BeauHD on 08/10/2026 at 11:00 pm

    An anonymous reader quotes a report from TechCrunch: The Trump administration is suspending Microsoft, Adobe, and several other technology companies from a program that helps skilled foreign workers obtain permanent residency in the United States, accusing the companies of fraud. "Our message to Microsoft is: You're a great American company, but you've got to hire great American workers," U.S. Vice President JD Vance said in a news conference on Thursday, Reuters reported. The other firms being suspended from the program include Capgemini, Cognizant, HCL, Infosys, Tata, and Wipro. Secretary of Labor Keith Sonderling said the government would not accept any new or pending permanent labor certification applications involving these companies. H-1B visas are designed for highly skilled positions that employers may struggle to fill with qualified U.S. workers. Tech companies are among the largest users of the program, with nearly three-quarters of approved visas going to workers from India, according to The Associated Press. Vance also said during the news conference that the administration would investigate nine universities, including Harvard, Yale, and Stanford, over allegations they're abusing a program that allows international students to come to the U.S. and were using the program to undermine wages for American workers. "We believe in the strength and talent of the American workforce," a Microsoft spokesperson said in a statement. "That is why the vast majority of Microsoft employees in the United States are Americans. We look forward to providing the Administration with additional information. For example, of the approximately 6,000 H-1B visa applications we submitted in the last fiscal year, 80% percent were to extend or change the status of existing Microsoft employees." "These were not to hire new people. The remaining filings for new employees were for individuals already legally in the United States who decided to come work for us, and they equal only 1% of our U.S. workforce. They are not new arrivals to our country." Read more of this story at Slashdot.

  • Emmy Awards Leave Broadcast TV For Prime Video
    by BeauHD on 08/10/2026 at 7:00 pm

    Amazon Prime Video will become the exclusive global home of the Emmy Awards under a six-year deal beginning in 2027, the Television Academy announced on Tuesday. The Emmys will stream live for free to viewers in more than 240 countries and territories without requiring a Prime subscription. From the report: In the release, Prime Video was named as the "permanent home" for the Emmys, in contrast to the rotating agreement in place years prior. The switch ends the traditional "wheel-deal" setup to broadcast the awards, where ABC, CBS, NBC and Fox took turns hosting the Emmys each year. The system has been in place since at least 1994, with the most recent eight-year contract expiring this year. "Television has never been more global, and the Emmys should be a celebration that the world can share," Television Academy chair Cris Abrego said in a statement. "Having a dedicated home with Prime Video allows us to build on that legacy with unprecedented global reach and a broader commitment to the Television Academy and our mission throughout the year."
