While many developers are struggling to keep up with the flood of vulnerability reports, others are still focused on preventing those reports from happening in the first place. Control-flow integrity (CFI) is the term for preventing (or at least detecting) exploits that divert the flow of control from its intended paths. At the 2026 GNU Tools Cauldron, Kees Cook presented his changes to the GCC compiler suite to support forward-edge CFI for the kernel.

Cloudflare Keeps 1.1.1.1 Out of Piracy Blocking, Escapes Penalties In France

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

Oct 09, 2026 11:00 | Source: slashdot.org

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.

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.

First Thorium Nuclear Clocks Begin to Tick

Oct 09, 2026 03:00 | Source: slashdot.org

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.

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."

Linux Moves Closer to Retiring the x32 ABI After Years of Limited Adoption

Oct 08, 2026 16:00 | Source: linuxjournal.com

by George Whittaker Linux kernel developers are renewing efforts to retire the x32 application binary interface (ABI), a little-used compatibility feature that attempted to combine the advantages of 64-bit processors with the smaller memory footprint of 32-bit applications. A revised patch series submitted on October 8, 2026, proposes the first steps toward disabling the interface, potentially ending support for an architecture experiment introduced more than 14 years ago. The latest proposal comes from Sebastian Andrzej Siewior, a Linux kernel developer at Linutronix who has been working on the removal effort throughout 2026. Rather than immediately deleting every component associated with x32, the proposed approach would first prevent the feature from being enabled through normal kernel configuration. This would give remaining users and distribution maintainers an opportunity to respond before the underlying implementation is removed. The effort reflects a broader challenge in Linux development: maintaining compatibility with older or rarely used technologies while keeping the kernel manageable, secure, and efficient. Although x32 offered theoretical performance and memory advantages, it never achieved widespread adoption. With conventional x86_64 software dominating modern Linux systems, developers are increasingly questioning whether the additional maintenance burden remains justified. Understanding the Linux x32 ABI The x32 ABI was introduced with Linux kernel 3.4 in 2012 as an alternative to conventional 32-bit and 64-bit application environments. Its goal was to provide applications with access to the architectural improvements of x86_64 processors while retaining smaller data types and pointers associated with 32-bit software. Traditional 32-bit x86 applications use the i386 ABI, which operates with a more limited register set and 32-bit execution conventions. Standard x86_64 applications, meanwhile, benefit from additional general-purpose registers, wider registers, and modern calling conventions, but they normally use 64-bit pointers. Those larger pointers can increase memory consumption in applications that maintain large numbers of pointer-heavy data structures. The x32 ABI attempted to offer a compromise. Applications would execute using the x86_64 instruction set and its larger register file while retaining 32-bit integers, long values, and pointers. This programming model is commonly described as ILP32, meaning that integers, long integers, and pointers are all 32 bits wide. The distinction can be illustrated by comparing the expected sizes of common C data types: Go to Full Article
