  • Some Datacenters Divert Power from Homes. Will It Drive Homeowners to Solar and Batteries?
    by EditorDavid on 17/05/2026 at 1:34 am

    An anonymous reader shared this report from Electrek: A Nevada utility just told 49,000 Lake Tahoe residents that it's redirecting 75% of their electricity supply to data centers, and they have less than a year to find a new power source. It's one of the starkest examples yet of the AI boom's impact on everyday Americans... NV Energy needs the capacity for data centers being built by Google, Apple, and Microsoft around the Tahoe-Reno Industrial Center east of Reno, according to Fortune... Data centers drove half of all US electricity demand growth last year.... That dynamic — small residential customers losing out to massive industrial electricity buyers — is exactly what's driving the broader shift to distributed solar and storage. When the grid becomes unreliable or unaffordable because of data center demand, the homeowners who have solar panels and a battery in the garage are the ones with options. "The shift is measurable," they argue: Third-party ownership models (leases and power purchase agreements), which still qualify for the [U.S.] commercial investment tax credit through 2027, are projected to grow 25% in 2026 and capture up to 69% of residential installations, up from roughly 45% in 2025. Homeowners aren't waiting for incentives to come back — they're finding new ways to get solar on their roofs... [A] battery that can store cheap solar energy and deploy it during peak hours is increasingly essential. California utility customers alone are adding roughly 8,000 new home batteries per month — about 100 MW of new storage capacity. Municipal programs are accelerating the trend. Ann Arbor, Michigan, recently became the first US city to directly deploy solar and battery systems on 150 homes through its city-owned utility. Vermont's Green Mountain Power is offering home batteries at little to no upfront cost. These programs signal that utilities themselves recognize the value of distributed energy.

  • An Entire Wikipedia That's 100% AI Hallucinations
    by EditorDavid on 16/05/2026 at 10:34 pm

    "Every link leads to an entry that does not exist yet," explains the GitHub page for a Wikipedia-like site called Halupedia. "Until you click it, at which point an LLM pretends it has always existed and writes it for you, in the deadpan register of a 19th-century scholarly press..." Every article is invented on demand. The footnotes are also lies... The hardest problem with an infinite, on-demand encyclopedia is internal contradiction... When the LLM writes an article, it is required to add a context="..." attribute on every <a> it inserts, summarising the future article it is linking to (e.g. context="19th-century clerk who formalized footnote drift, Pellbrick's mentor")... When that target article is later requested for the first time, the worker loads the accumulated hints and injects them into the system prompt as "PRIOR REFERENCES — these are CANON". The LLM is instructed that the encyclopedia is hallucinated and absurd, but it must not contradict itself. Fast Company reports that Halupedia was created by software developer BartÅomiej Strama, who confessed in a Reddit comment that the site came about after a drunk night with a friend. In the week since launch, he says Halupedia has amassed more than 150,000 users." Beyond indulging in silly alternate histories, what's the point of using Halupedia? Strama hinted at one larger purpose in a reply to a donor on his Buy Me a Coffee page: "Your contribution towards polluting LLM training data will surely benefit society!" he wrote. The site is licensed as free software under the GPL-3.0 license. Thanks to long-time Slashdot reader schwit1 for sharing the news. Read more of this story at Slashdot.

  • How I Added an LLM-Based Grammar Checking + TeX Math Import To LibreOffice
    by EditorDavid on 16/05/2026 at 9:34 pm

    Former Microsoft programmer Keith Curtis "wrote and self-published After the Software Wars to explain the caliber of free and open source software," according to his entry on Wikipedia, "and why he believes Linux is technically superior to any proprietary OS." He's also KeithCu (long-time Slashdot reader #925,649), and has written a blog post on "How I added an LLM-based grammar checking + TeX math import to LibreOffice." : At Microsoft, I spent five years working on the text components RichEdit and Quill, and came to understand the "physics" of word processing: the file formats, data structures, and algorithms that provided fast access to text and properties, independent of the length of the file. Selecting one million characters to make them bold took about the same time as changing one character, because of the clever data structures (piece tables) and algorithms in these engines... When I decided to add a real-time AI grammar checker to [LibreOffice plugin] WriterAgent, I knew what I was getting into, but I underestimated the trickery of LibreOffice's UNO. His site shares the surprises he encountered, one by one. (Starting with "the office suite throws a bunch of initialization variables at your constructor. If your Python __init__ method doesn't handle them, the code fails to map the call, the stack misaligns, and the program dies.") There's sentence casing issues, duplicate words, and foreign-language syntax — all culminating in new features for "a LibreOffice extension (Python + UNO) that adds generative AI editing to Writer, Calc, and Draw..." "If you want to try it out, the repo is here... Let's make LibreOffice and the free desktop AI-native!" Read more of this story at Slashdot.

  • The Apple-OpenAI Alliance is Fraying, Setting Up a Possible Legal Fight
    by EditorDavid on 16/05/2026 at 8:34 pm

    Bloomberg reports that Apple's two-year-old partnership with OpenAI "has become strained, according to people familiar with the matter." Bloomberg describes OpenAI as "failing to see the expected benefits from the deal and now preparing possible legal action." OpenAI lawyers are actively working with an outside legal firm on a range of options that could be formally executed in the near future, said the people, who asked not to be identified because the deliberations are private. That could include sending the iPhone maker a notice alleging breach of contract without necessarily filing a full lawsuit at the outset, according to the people... OpenAI believed that the companies' partnership, which wove ChatGPT into Apple software, would coax more users into subscribing to the chatbot. It also expected deeper integration across more Apple apps and prime placement within the Siri assistant. Instead, Apple's use of OpenAI technology across its operating systems remains limited, and features can be hard to find... Apple has had its own concerns about OpenAI, including whether the company does enough to protect user privacy. And a recent push [by OpenAI] to make devices — an effort overseen by former Apple executives — has rankled the iPhone maker. Any legal move by OpenAI likely wouldn't come until after the conclusion of the Musk trial, according to the people. No final decisions have been made, and OpenAI still hopes to resolve its issues with Apple outside of court. The article points out that OpenAI "initially believed the deal could generate billions of dollars per year in subscriptions — something that hasn't come close to happening." An OpenAI executive argues to Bloomberg that from a product perspective Apple hasn't done everything they could, "and worse, they haven't even made an honest effort."

  • California Law Limits 'Recyling' Logo in New Attack on Plastic Waste
    by EditorDavid on 16/05/2026 at 7:34 pm

    "Most of the plastic waste in California is about to lose the recycling symbol," writes the Washington Post's "climate coach." The "chasing arrows" symbol, created in 1970 by a college student inspired by the burgeoning environmental movement, has been stamped indiscriminately on plastic bottles, clamshell takeout containers, chip bags and more for decades. The majority of the items emblazoned with the mark have been virtually impossible to recycle for most people. California lawmakers say they want to end the charade: Under what's known as the Truth in Recycling law, plastics cannot use the symbol if they aren't collected by curbside programs serving 60% of Californians and sorted by facilities serving 60% of the state's recycling programs (with some additional requirements). If the law goes into effect as scheduled on October 4, more than half of the types of plastic packaging and products sold in the state can no longer carry the chasing arrows logo. That will affect plastic films, foam, PVC and mixed plastics... Food and packaging groups have sued the state of California, calling the law a form of censorship whose vague restrictions violate the First Amendment and due process rights.... Advocates of the law counter that corporations deliberately misled the public by turning the recycling symbol into a marketing device that masks the fact that only a small fraction of plastic packaging is ultimately recycled... The mark was originally intended to informwaste processors what polymers a plastic item was made from. But the public reasonably assumed anything stamped with the symbol was recyclable. Millions of tons of worthless plastic trash have since poured into recycling facilities unable to process it.... States are now taking action. Seven have passed laws shifting the cost of recycling onto packaging makers. Oregon and Washington have lifted requirements that plastic containers carry the chasing arrows symbol. The article notes that Norway already recovers 97% of beverage bottles, while Slovakia recycles 60% of plastic packaging. "But the U.S. only recovers about a third of its PET and HDPE bottles, and just 13% of plastic packaging, according to U.S. Plastics Pact, an industry-led forum. "It won't be easy for the U.S. to reach higher levels of recycling: The necessary infrastructure and incentives are chronically underfunded, no federal mandate exists for minimum-recycled-content that would create demand and a mix of mostly unrecyclable hydrocarbons still dominates the waste stream."

  • Anthropic's Mythos Helped Build a Working macOS Exploit in Five Days
    by EditorDavid on 16/05/2026 at 6:34 pm

    "The vulnerability is simple in practice," writes Tom's Hardware: "run a command as a standard user and gain root (administrator) access to the machine." And it was Mythos Preview that helped the security researchers at Palo Alto-based Calif bypass a five-year Apple security effort in just five days. The blog 9to5Mac reports: Last year, Apple introduced Memory Integrity Enforcement (MIE), a hardware-assisted memory safety system designed to make memory corruption exploits much harder to execute... [The researchers note it's built into Apple all models of the iPhone 17 and iPhone Air, and some MacBooks] They explain they have a 55-page technical report on the hack, but they won't release it until Apple ships a fix for the exploit. But they do note in broad terms that Anthropic's Mythos Preview model helped them identify the bugs and assisted them throughout the entire collaborative exploit development process. "Mythos Preview is powerful: once it has learned how to attack a class of problems, it generalizes to nearly any problem in that class. Mythos discovered the bugs quickly because they belong to known bug classes. But MIE is a new best-in-class mitigation, so autonomously bypassing it can be tricky. This is where human expertise comes in. Part of our motivation was to test what's possible when the best models are paired with experts. Landing a kernel memory corruption exploit against the best protections in a week is noteworthy, and says something strong about this pairing...." [I]n a time when even small teams, with the help of AI, can make discoveries such as this one, "we're about to learn how the best mitigation technology on Earth holds up during the first AI bugmageddon."
