  • Trump Signs AI Executive Order Asking Companies To Give Government Early Access To Models
    by BeauHD on 02/06/2026 at 6:00 pm

    An anonymous reader quotes a report from CNBC: President Donald Trump on Tuesday signed an executive order asking artificial intelligence companies to provide models to the federal government to assess their capabilities ahead of a full release. The order asks companies, on a voluntary basis, to participate in a benchmarking process to assess a model's "advanced cyber capabilities" and determine whether it should be considered a "covered frontier model." It then asks for access to those models up to 30 days before the companies plan to release them more broadly, and enables the government to help select the "trusted partners" that will receive early access. "Nothing in this section shall be construed to authorize the creation of a mandatory governmental licensing, preclearance, or permitting requirement for the development, publication, release, or distribution of new AI models, including frontier models," the order said. Trump signed the order in private, just weeks after he postponed a signing ceremony with prominent tech CEOs because he "didn't like certain aspects of it," he told reporters at the time. [...] Trump's AI order outlines several timeframes to develop directives and other guidance, specifically calling on the Department of Defense to prioritize the cyber defense of its information systems.

  • Adafruit Pauses Blog After Demand Letter From Flux.ai's Lawyers
    by BeauHD on 02/06/2026 at 5:00 pm

    Longtime Slashdot reader Matt_Bennett shares a blog post from Adafruit: Adafruit received at 10:38 p.m. ET on May 22, 2026 a letter from former FBI chief of staff, Jonathan F. Lenzner, and partner at Fenwick & West LLP, counsel for Flux, demanding, among other things, that Adafruit refrain from publishing an article addressing what the letter characterizes as false and potentially defamatory claims about Flux, including statements about Flux's intellectual property, commercial traction and user base. The letter further asserts claims under the Computer Fraud and Abuse Act. Adafruit accessed only information that Flux's own systems made publicly available through a server misconfiguration. Adafruit's reporting concerns a matter of public security interest and was conducted in the ordinary course of responsible disclosure. Although Adafruit vigorously rejects the assertions made in Flux's May 22, 2026 demand letter, we have temporarily stopped publishing on the Adafruit blog while we consider our response and next steps. We will update the community as appropriate. For context, Adafruit is a major open-source hardware company and electronics retailer known for its maker-focused boards, components, tutorials, and community publishing. Flux.ai is relevant because it is building an AI-assisted circuit-board design platform aimed at changing how engineers create and collaborate on PCB designs. "Adafruit probably did a review of AI PCB tools," writes HN user karmicthreat. "I've used Flux.ai before; it was a pretty bad experience. After about 50-100$ in tokens a couple of times, I couldn't get more than a couple of simple components on the schematic. And not in sensible positions..." Redditor AlexTaradox adds: "Nothing was published as far as I know. I assume they did review of AI tools and likely contacted flux with some preliminary results, but flux saw where it is going and decided to block them from publishing any results. Flux is garbage and they obviously know it, but they need to hold for some time until some other scam acquires them. Doing anything with them is just asking to be screwed..." Further discussions are taking place on Reddit and Hacker News. Read more of this story at Slashdot.

  • User-Replaceable Batteries Are Coming Back In a Big Way
    by BeauHD on 02/06/2026 at 4:00 pm

    New EU battery rules taking effect early next year are pushing tech makers toward user-replaceable batteries in products like headphones, e-readers, handheld consoles, laptops, and possibly earbuds. But carve-outs for smartphones and tablets may mean replaceable batteries won't necessarily return to phones in the way many users remember. The Verge's Dominic Preston reports: Since the upcoming law doesn't actually come into force until February 18th, 2027, companies still have plenty of time to get their ducks in a row. Still, it's likely that before then we'll see more and more manufacturers launch products with user-replaceable batteries, across audio, e-readers, gaming handhelds, and more. Only time will tell whether most of those products are EU only, or whether the new European laws shape the nature of tech worldwide. It's likely that some product categories will move slower than others. Tech companies will have breathed a sigh of relief that wearables look likely to be exempt, but if wireless earbuds aren't carved out as well then there may be a scramble to adapt the miniature designs for easy replaceability. "The in-ear form factor demands extreme miniaturization, to fit the driver, antenna, processor, microphones and battery," notes a recent report from consultants Futuresource, going on to suggest that meeting the requirements will make earbuds both bigger and more expensive to manufacture. There also remains uncertainty about how some elements of the law will be interpreted. The law requires that user repairs be possible using "commercially available tools," which are "tools available on the market to all end-users." Right to Repair Europe's Alberico points out that this is a broad definition, likely to include a lot of tools not found in most houses, so there will likely be nothing to stop manufacturers requiring the sorts of less common screws that require dedicated electronics tool kits. There's also no strict definition of the "reasonable" price that manufacturers are required to set for spare parts. "That will likely take time -- and possibly litigation -- to clarify in practice," Alberico says. "But without fair access to affordable spare parts, repair will struggle to become the simplest and most attractive option for consumers." The big disappointment is that the separate phone and tablet legislation means we won't see any real changes there, so long as manufacturers make their batteries and devices durable. "This creates a false tradeoff between durability and repairability," Alberico says. "Robust, waterproof devices should not have to come at the expense of user-replaceable batteries. While the ecodesign legislation requirements meant an improvement in battery durability and replaceability, at Right to Repair Europe we'll continue to advocate for all products to be designed with user-replaceable batteries." Whether the EU will listen remains to be seen. Otherwise, the main product people seem to want to replace the battery in may remain one of the only ones where they can't.

  • GitHub Copilot Users React To New Usage-Based Pricing System
    by BeauHD on 02/06/2026 at 3:00 pm

    An anonymous reader quotes a report from Ars Technica: In April, GitHub announced that it was moving subscribers from request-based billing to a usage-based model for its AI-powered Copilot service. As that new pricing model goes into effect today, many GitHub Copilot users are reporting some extreme sticker shock as they realize just how quickly their previous "normal" usage is burning through their newly limited monthly allotment of AI credits. Across social media and forums, many Copilot users are sharing personal statistics showing how just a few hours of AI usage can now account for a large chunk of their new monthly subscription caps. For some users, it reportedly took less than a day to use up a month's usage quota. That's a big change from previous months, when GitHub Copilot subscribers were allocated a certain number of "requests" and "premium requests" based on their payment tier. GitHub said that the old system meant that "a quick chat question and a multi-hour autonomous coding session [could] cost the user the same amount," forcing Copilot itself to "absorb much of the escalating inference cost behind that usage." [...] Indeed, some Copilot users have been sharing estimates from GitHub's own tool showing that their previous monthly usage would rack up bills in the thousands of dollars under the new pricing plan. Under GitHub's new usage-based pricing system, paid Copilot subscriptions instead grant users a certain number of AI "credits" each month, with one credit corresponding to $0.01 of usage. Subscribers also get bonus credits depending on their subscription level: the $10/month Pro plan includes 1,500 credits ($15 worth); the $39 Pro+ plan includes 7,000 credits ($70 worth); and the $100/month Copilot Max plan includes 20,000 credits ($200 worth). The precise number of Copilot credits used by a given prompt is determined by the number of input and output tokens used and the rates charged by the underlying large language model. That means pricing is highly dependent not just on the type of request but on the specific model that a user chooses. One million output tokens from OpenAI's GPT-5.4 nano would run just $1.25 on GitHub Copilot, but that same level of output would run $30 on the frontier GPT-5.5 model (Copilot users who rely on "Auto" mode to pick the most appropriate available model for any request should be extremely careful, as some users report it can switch to expensive models for extremely simple queries).

  • Google Requests Permission to Release 32 Million Mosquitoes In California and Florida
    by BeauHD on 02/06/2026 at 11:00 am

    Google has asked the EPA for permission to release up to 32 million sterile male mosquitoes in California and Florida over two years. The effort is part of the company's Debug program, which uses Wolbachia-infected males to reduce populations of disease-spreading Aedes aegypti mosquitoes. Google cites a similar approach in Singapore that helped suppress mosquito populations and reduce dengue cases. The Guardian reports: As part of its successful "Debug" program, Google is tapping into its tech expertise to raise an army of sterile male mosquitoes to lower the number of illness-spreading bugs. Mosquitoes -- the world's deadliest animal -- kill more people than any other creature in the world every year by spreading lethal diseases such as dengue, West Nile virus, Zika, chikungunya and malaria. A notice (PDF) from the federal register shows the US Environmental Protection Agency (EPA) is reviewing Google's request to release up to 16 million mosquitoes annually, in Florida and California, over the span of two years. The EPA will decide whether to greenlight Google's request for an experimental use permit after a public comment period, which ends on 5 June. Male mosquitoes don't bite or carry disease. One of the main approaches Google is testing involves rearing male mosquitoes with a naturally occurring bacteria, called wolbachia, which stops them from having offspring with wild female mosquitoes. When an infected male tries to mate with a wild female, her eggs won't hatch; Google explains in a blog post: "the population gets smaller with each generation." Read more of this story at Slashdot.

  • Texas Adds Another Huge Solar Farm As ERCOT Grid Demand Soars
    by BeauHD on 02/06/2026 at 7:00 am

    Texas is adding another large solar project as ERCOT electricity demand rises. According to Electrek, Vesper Energy has secured $236 million in financing for its 201 MW Nazareth Solar farm in Swisher County, which will be capable of generating enough electricity for about 53,000 homes. The project is expected to begin construction in June 2026 and come online in fall 2027. From the report: Nazareth Solar will sit on more than 2,400 acres of private land and generate enough electricity to power around 53,000 homes annually. The project will neighbor Vesper's Hornet Solar (pictured above), another large solar farm the company developed. ERCOT faces growing demand from population growth, industrial expansion, and power-hungry data centers. And despite political attacks on renewables, solar continues getting built in this red state because it's one of the fastest and cheapest ways to add new electricity to the grid. Vesper says the project will bring new tax revenue to local schools, infrastructure, and emergency services, along with construction jobs and long-term operations roles. Participating landowners are also expected to receive long-term lease income from the solar farm. Read more of this story at Slashdot.
