  • Canonical is Funding a PhD to Automate C to Rust Translation
    by EditorDavid on 23/08/2026 at 2:34 pm

    An anonymous reader shared this report from the blog It's FOSS: Canonical has committed funding to a three-year PhD project focused on building a system that can automatically translate large C codebases into Rust. And they are not alone; UK Research and Innovation is matching their funding for the project, which is set to run through the University of Bristol's Programming Languages Research Group. The PhD is aiming to build an all-encompassing platform that can take a C repository running into hundreds of thousands of lines and translate it into Rust that's "safe, behaviourally correct and maintainable Rust." The work will be carried out by a student, Alex Wood, who will be supported by Professor Meng Wang leading the work, with Dr. Cristina David and Canonical's Jon Seager serving as co-supervisors.

  • Supply Chain Issues Delaying US Grid Batteries' Installation
    by EditorDavid on 23/08/2026 at 11:34 am

    Falling prices have made grid-scale storage batteries more attractive, reports Bloomberg. But after decades of stagnant investment, America's grids "are racing to make the upgrades needed to plug them in," with supplies straining for the necessary equipment. Demand for batteries has skyrocketed as electricity use across the U.S. swells, driven by data centers' booming energy needs and increasing electrification. It's also getting harder to get them connected to power grids... As those upgrades get delayed, storage projects are piling up in interconnection queues from coast to coast. For example, Consolidated Edison Inc., a major utility in New York state, says over the last two years the volume of battery storage projects waiting to be connected has grown by 300%... "The whole process of interconnecting these new power plants got really log-jammed and bottlenecked," said Joseph Rand, an energy policy researcher at the Lawrence Berkeley National Laboratory... Nationwide, some 750 gigawatts of energy storage projects — roughly equivalent to the generating capacity of more than 700 nuclear reactors — are in line to get grid connections, according to the lab's research. Not all of these projects will get built. Many developers already abandoned the queue because of delays. Still, the waiting time is increasing; the median was five years in 2025, up from a year and a half in 2015. The flood of battery projects is expected to continue. Wood Mackenzie, an energy consultancy, projects the U.S. energy storage market will quadruple in the next six years... [Shortages in key equipment] have driven up construction costs and time lines for grid upgrades, leaving utilities struggling to build fast enough. A drought of skilled workers is further slowing them down... In California, PG&E Corp., the state's largest utility, told regulators in January that a key driver of delays was long lead times for specialized equipment. Procuring certain breakers could take nearly four years, according to the utility, which reported a 300% increase in its interconnection workload compared to prior years. In Northern California, for example, holdups to circuit breaker upgrades to a substation in Solano County led to projected delays for two battery projects worth a combined 450 megawatts. Transmission line work in the Bay Area has put another 800 megawatts of energy storage at risk of delay, according to PG&E. Last year New York's Con Ed started requiring developers to help pay for upgrades if their projects will push power demand and strain infrastructure. But that also drew criticism: According to a survey conducted by the trade group New York Battery and Energy Storage Technology Consortium (NY-BEST), the new methodology raised costs by an average of $21 million per project, a 14-fold increase. At least 25 projects have been canceled as a result, according to the group. Battery advocates have appealed to state regulators to get Con Ed to abandon the new policy.

  • Debian is Voting on Whether to Allow AI-Assisted Contributions
    by EditorDavid on 23/08/2026 at 7:34 am

    Debian developers are voting on whether to ban AI-assisted contributions, reports the blog Linuxiac, with a ballot listing eight proposals and a "None of the above" option. The first one is still the original proposal to ban LLM-assisted contributions by changing the Debian Social Contract. This would stop generative AI from being used for direct Debian work like packaging, software, documentation, translations, websites, and project communication. However, upstream projects made with AI help would not be affected. The proposal gives several reasons for the ban, such as unclear copyright and licensing, doubts about the reliability of AI-generated work, extra review work for maintainers, aggressive scraping of Free Software resources, and the high resource use of large AI systems... The second option would clearly allow contributions that are partly or fully made by an LLM, as long as contributors check their technical quality, security, licensing, and usefulness, fully understand the changes, and disclose major AI help. It would also ban sending private or sensitive Debian information to untrusted external AI services. A similar fourth option recognizes worries about generative AI but says banning it would be hard to enforce and not helpful. This proposal would accept AI-assisted Debian work if it follows the Debian Free Software Guidelines, is properly reviewed and understood by the contributor, and is marked as AI-assisted when needed. The fifth proposal is even more open. It says Debian should not support or ban generative AI tools, but should apply the same standards for quality, correctness, maintainability, and legality to all contributions, no matter how they were made... One unique proposal is called "Debian is created by humans." Instead of banning AI tools for contributors, it focuses on what actually gets included in Debian. With this approach, contributors could use generative AI for research, analysis, exploration, or critique, but could not submit AI-generated output directly as Debian packaging, patches, documentation, bug reports, project communications, or other Debian work. As the proposal says: humans create Debian. Another, much stricter proposal asks Debian contributors to avoid LLM use as much as possible. It would require all Debian communication, like bug reports, mailing-list messages, Salsa discussions, and Planet Debian posts, to be written only by humans. Any AI use in Debian work would have to be disclosed, and violations could be handled under the project's Code of Conduct. The CEO/founder of AI-native compliance management platform company Strike Graph believes a Debian AI ban is "the wrong fix for the actual problem" at hand, reports The New Stack: "Debian's ban isn't really about banning AI," [CEO Justin] Beals says. "It's an admission that nobody has built a reliable way to verify what an AI agent actually produced before it lands in a codebase this many systems depend on, including infrastructure running in orbit. That's a legitimate thing to be worried about...." He thinks that any policy statement that says AI isn't allowed simply won't hold up, as the tooling keeps getting harder to detect... Looking across the complete set of tabled propositions, proposal A (no LLM contributions to Debian via social contract) needs a 3:1 majority to pass; the other seven proposals (B to H) need a simple majority.

  • Defamation Suit Demanding Elsevier Retract Paper Heads Closer To Trial
    by EditorDavid on 23/08/2026 at 4:33 am

    Retraction Watch reports: A trial date has been set in a $1 billion defamation case against Elsevier that alleges the company published what plaintiffs say was a manipulated study about an air purifying technology over objections from peer reviewers. The case has already cost Elsevier a $10,000 sanction from a judge. Global Plasma Solutions (GPS), which makes air quality products, sued Elsevier in 2022 after the publisher declined to retract a 2021 paper in Building and Environment about GPS' needlepoint bipolar ionization technology, which it heavily marketed during the COVID-19 pandemic as an air purifier. The complaint claims Elsevier is responsible for the authors' alleged omission of data and misleading conclusions in the paper that fueled "massive" financial losses for the company, its lawyers claim. Elsevier knew the paper "failed peer review" under its "own standards," but moved forward with the article despite this knowledge, according to GPS, which now goes by GPS Air. The complaint has survived a bid by Elsevier to dismiss the case, and a trial has been set for Dec. 7. In allowing the case to proceed, U.S. Magistrate Judge David Keesler said in a May 2024 opinion that GPS has "plausibly alleged actual malice" by Elsevier defined as "knowledge of falsity or reckless disregard for the truth." Chief Judge Martin Reidinger of the U.S. District Court for the Western District of North Carolina upheld Keesler's recommendation in July 2025... Citing internal and discovery documents, GPS alleges an assessment of 19 journals revealed Elsevier has published more than 1,200 articles either without any peer review, or against the recommendations of the reviewers.

  • Microsoft Blames Windows Gaming Issues On RGB Lighting Devices
    by EditorDavid on 23/08/2026 at 2:29 am

    BleepingComputer reports: Microsoft says ongoing issues causing games to crash or fail to launch after installing the August 2026 Windows updates may be caused by peripherals with RGB lighting. As Microsoft explained when it confirmed it's investigating on Wednesday, this known issue affects games like ARC Raiders, MARVEL Tokon: Fighting Souls, and The Finals on systems running Windows 11 24H2 and 25H2... "[Peripherals or internal device components with RGB lighting features] may install drivers or code components with file names similar to inpoutx64. In systems where these drivers are found, the issue is then triggered by launching certain games," it noted. Thanks to Slashdot reader joshuark for sharing the article.

  • Battery Fires At Recycling Centres Are Costing the UK £1bn a Year
    by EditorDavid on 23/08/2026 at 12:29 am

    Wrongly discarded lithium batteries, such as those in vapes, are causing more than 10 fires a week at U.K. recycling centers, according to figures shared with the Guardian: The Environment Services Association (ESA), the trade body for waste management companies, said its members had reported 1,518 fires in the year to March 2026. At least 541 of these fires were directly attributed to lithium ion batteries, the survey found. There were a further 216 battery fires in bin lorries [garbage trucks]. The ESA said the reported number of battery-related fires underestimated the scale of the problem, because in most incidents it was impossible to determine the cause of the blaze. A spokesperson said: "We know 40% of fires at recycling centres are caused by batteries, but we think the actual number is more like 70%." It estimates that annual cost of these fires has increased from £150m in 2021 to £1bn today... The ESA is calling for a £5 deposit scheme on the sale of all vapes to ensure that vape users have an incentive to return used devices to retailers for safe disposal... [Patrick Brighty, the head of recycling policy at the ESA, said] "Vapes are among the biggest culprits because they're cheap, abundant and typically have a short use-life."
