  • Arduino's New Terms of Service Worries Hobbyists Ahead of Qualcomm Acquisition
    by BeauHD on 24/11/2025 at 10:00 pm

    An anonymous reader quotes a report from Ars Technica: Some members of the maker community are distraught about Arduino's new terms of service (ToS), saying that the added rules put the company's open source DNA at risk. Arduino updated its ToS and privacy policy this month, which is about a month after Qualcomm announced that it's acquiring the open source hardware and software company. Among the most controversial changes is this addition: "User shall not: translate, decompile or reverse-engineer the Platform, or engage in any other activity designed to identify the algorithms and logic of the Platform's operation, unless expressly allowed by Arduino or by applicable license agreements ..." In response to concerns from some members of the maker community, including from open source hardware distributor and manufacturer Adafruit, Arduino posted a blog on Friday. Regarding the new reverse-engineering rule, Arduino's blog said: "Any hardware, software or services (e.g. Arduino IDE, hardware schematics, tooling and libraries) released with Open Source licenses remain available as before. Restrictions on reverse-engineering apply specifically to our Software-as-a-Service cloud applications. Anything that was open, stays open." But Adafruit founder and engineer Limor Fried and Adafruit managing editor Phillip Torrone are not convinced. They told Ars Technica that Arduino's blog leaves many questions unanswered and said that they've sent these questions to Arduino without response. "Why is reverse-engineering prohibited at all for a company built on openly hackable systems?" Fried and Torrone asked in a shared statement. There are also concerns about the ToS' broad new AI-monitoring powers, which offer little clarity on what data is collected, who can access it, or how long it's retained. On top of that, the update introduces an unusual patent clause that bars users from using the platform to identify potential infringement by Arduino or its partners, along with sweeping, perpetual rights over user-generated content. This could allow Arduino, and potentially Qualcomm, to republish, modify, monetize, or redistribute user uploads indefinitely. Read more of this story at Slashdot.

  • Americans Are Holding Onto Devices Longer Than Ever
    by msmash on 24/11/2025 at 9:21 pm

    An anonymous reader shares a report: The average American now holds onto their smartphone for 29 months, according to a recent survey by Reviews.org, and that cycle is getting longer. The average was around 22 months in 2016. [...] Research released by the Federal Reserve last month concludes that each additional year companies delay upgrading equipment results in a productivity decline of about one-third of a percent, with investment patterns accounting for approximately 55% of productivity gaps between advanced economies. The good news: businesses in the U.S. are generally quicker to reinvest in replacing aging equipment. The Federal Reserve report shows that if European productivity had matched U.S. investment patterns starting in 2000, the productivity gap between the U.S and European economic heavyweights would have been reduced by 29 percent for the U.K., 35 percent for France, and 101% for Germany.

  • Udio Users Can't Download Their AI Music Creations Anymore
    by msmash on 24/11/2025 at 8:43 pm

    An anonymous reader shares a report: As part of the settlement with Universal, Udio has amended its terms of service, and users can no longer download their outputs. This has AI music makers furious, and with good reason. Unfortunately, they have little recourse, as the contract they sign when creating a Udio account includes a waiver of the right to bring a class action. Read more of this story at Slashdot.

  • Obesity Jab Drug Fails To Slow Alzheimer's
    by msmash on 24/11/2025 at 8:01 pm

    Drug maker Novo Nordisk says semaglutide, the active ingredient for the weight loss jab Wegovy, does not slow Alzheimer's -- despite initial hopes that it might help against dementia. From a report: Researchers began two large trials involving more than 3,800 people after reports the medicine was having an impact in the real world. But the studies showed the GLP-1 drug, which is already used to manage type 2 diabetes and obesity, made no difference compared to a dummy drug. The disappointing results are due to be presented at an Alzheimer's disease conference next month and are yet to be published in a peer-reviewed journal. Read more of this story at Slashdot.

  • Google's 'Aluminium OS' Will Eventually Replace ChromeOS With Android
    by msmash on 24/11/2025 at 7:20 pm

    Google's long-rumored plan to merge ChromeOS and Android into a single desktop operating system now has a name: Aluminium OS, AndroidAuthority reports, citing a job listing. The job listing explicitly tasks applicants with "working on a new Aluminium, Android-based, operating system." The job listing confirms Google intends to eventually replace ChromeOS entirely, though the two platforms will coexist during a transition period. Aluminium OS won't be limited to budget hardware -- the listing references "AL Entry," "AL Mass Premium," and "AL Premium" tiers across laptops, detachables, tablets, and mini-PCs.

  • Science-Centric Streaming Service Curiosity Stream is an AI-licensing Firm Now
    by msmash on 24/11/2025 at 6:41 pm

    Curiosity Stream, the decade-old science documentary streaming service founded by Discovery Channel's John Hendricks, expects its AI licensing business to generate more revenue than its 23 million subscribers by 2027 -- possibly earlier. The company's Q3 2025 earnings revealed a 41% year-over-year revenue increase, driven largely by deals licensing its content to train large language models. Year-to-date AI licensing brought in $23.4 million through September, already exceeding half of what the subscription business generated for all of 2024. The streaming service's library contains 2 million hours of content, but the "overwhelming majority" is earmarked for AI licensing rather than subscriber viewing, CEO Clint Stinchcomb said during the earnings call. Curiosity Stream is licensing 300,000 hours of its own programming and 1.7 million hours of third-party content to hyperscalers and AI developers. The company has completed 18 AI-related deals across video, audio, and code assets. Read more of this story at Slashdot.
