  • Amazon Trying to Launch a Global Satellite Cellphone Network In 2028
    by BeauHD on 27/07/2026 at 10:00 pm

    Amazon has asked the FCC to approve a 5,105-satellite constellation launching in 2028 that would provide global direct-to-cell "voice, messaging, data, and emergency services," similar to Starlink's partnership with T-Mobile. The network would use Globalstar spectrum, support future Apple satellite services, and complement Amazon's existing Leo broadband constellation. The Verge reports: Advanced Television points out that the FCC application also includes a request to use spectrum assigned to Iridium's satellite network outside the US, even as Rocket Lab is in the process of acquiring Iridium with plans to expand. The new constellation and direct-to-device service will "complement" the broadband services Amazon also plans to offer through its Leo platform. In addition to consumer satellite service, it would also be used for things like disaster response and emergency messaging. Amazon says the new direct-to-device satellites "will process the signals in orbit before relaying them to improve performance." The new constellation will be nearly double the size of Amazon's initial Leo constellation, which is planned to include around 3,200 satellites. As of July 2nd, Amazon says "over 375" of those satellites have launched so far. Read more of this story at Slashdot.

  • Nvidia, Tech Giants Launch AI Safety Initiative
    by BeauHD on 27/07/2026 at 9:00 pm

    wiredmikey shares a report from SecurityWeek: Nvidia and a large group of technology, cybersecurity, and enterprise software companies have launched new initiative aimed at developing and sharing open source tools, models, and techniques for securing AI systems and agents. The new Open Secure AI Alliance aims to give defenders more open tools for testing, auditing and protecting AI models and agents. Nvidia points to the recent security incident involving OpenAI and Hugging Face, noting that when closed AI tools could not differentiate between attackers and defenders and blocked forensic work, Hugging Face used the open-weight GLM 5.2 model on its own systems to review over 17,000 actions and contain the breach. "The right response is not to deny defenders access to capable open systems. It is to pair openness with strong safeguards, clear rules against malicious misuse, rigorous evaluation and rapid remediation. In cybersecurity, the safer path is the one that gives more defenders the ability to test, verify and strengthen the systems on which society relies," Nvidia said. Thanks to longtime Slashdot reader SphericalCrusher for also sharing the news. Read more of this story at Slashdot.

  • Codeberg Bans Cryptocurrency and LLM-Generated Code Projects
    by BeauHD on 27/07/2026 at 8:00 pm

    Longtime Slashdot reader AmiMoJo shares a report from Hackaday: Community-led open source project hosting site Codeberg has formally announced that projects whose code is largely or fully machine-generated through LLMs and other 'AI' tools will no longer be welcome. This follows on the heels of a similar ban on cryptocurrency-related projects. The community vote was on two issues, the first being the notion that scraping of project code for the use in LLMs should be forbidden, which was a motion that easily passed. The second motion was on disallowing projects whose code was substantially generated by LLMs like Claude, OpenAI Codex, and similar. This motion passed with 358 in favor versus 144 against. In the earlier linked blog post the reasoning behind especially this second issue is expanded upon, covering not only "license whitewashing," but also the direct and indirect hardware costs, with the expanding 'AI' datacenter hyperscaling having massively increased hardware costs for Codeberg over the past years, as the costs have been largely externalized. Also covered is the aspect of these LLM-based tools destroying the OSS community, which is something that is backed up by recent studies. Read more of this story at Slashdot.

  • China Begins Mass Production of Homegrown DUV Chip Tools
    by BeauHD on 27/07/2026 at 7:00 pm

    According to The Information (paywalled), a state-backed Shanghai company has begun mass-producing China's first homegrown immersion DUV lithography machines, with about five units expected this year for SMIC, Hua Hong, and CXMT. Roughly 20 more units are expected in 2027. Tom's Hardware reports: The Information didn't name the manufacturer, but its sources described the operation as having pulled DUV development teams from several Chinese companies, one of them the state-backed startup Shanghai Yuliangsheng Technology. SMIC has been testing a Yuliangsheng immersion tool since September 2025. Most components in the new systems are domestic, though some critical parts still come from Japan, and delays at local suppliers have held back output this year. [...] China accounts for around 20% of ASML's net sales this year, down from 33% in 2025, driven mainly by mainstream logic demand... Independent analysis from the AI Futures Project in June put commercial-scale Chinese immersion DUV in the mid-2030s, with ASML holding 98.7% of the immersion market. Qualifying the new machines for production lines could take many months, and they trail ASML's tools on performance and build quality. China's domestic EUV effort, which Reuters first reported as a working prototype in December, remains years away. Read more of this story at Slashdot.

  • ChatGPT Starts Blocking Direct Requests To Copy an Author's Style
    by BeauHD on 27/07/2026 at 6:10 pm

    An anonymous reader quotes a report from Ars Technica: OpenAI's ChatGPT is now refusing requests to generate text that directly mimics the style of famous authors. When asked to do so, the popular LLM instead offers a response that draws on the "broad qualities" of those authors "while remaining distinct in its own voice," for example. This morning, Ars received the following response to a test prompt asking for a story introduction in the style of Stephen King: "I can definitely write with the hallmarks of atmospheric, character-driven horror and small-town dread, but I can't write in Stephen King's exact style or closely imitate his distinctive voice. Here's an original opening that captures a similar feeling while remaining its own..." In testing, ChatGPT generated similar dodges for other authors both living (J.K. Rowling, Amy Tan) and dead (Charles Dickens, Ernest Hemingway). An analysis published by No Latency earlier this month (PDF) found the same behavior for living authors but found ChatGPT complied with style-copying requests for deceased authors. In refusing to directly copy the "exact style" of various authors, ChatGPT offered instead to capture an overall "feeling" by incorporating some of the common features found in those authors' work. That may seem like a distinction without a real difference at first glance. But the slight alteration could be legally important as OpenAI continues to fight a number of lawsuits brought by book authors alleging large-scale copyright infringement by models trained on their work. One of those suits specifically cites ChatGPT's "uncanny ability to generate text similar to that found in copyrighted textual materials," for instance. An OpenAI spokesperson did not respond to a request for comment from Ars Technica. In the US, copyright law generally protects only a specific expression of an idea, not the more intangible style of an author. But an AI-generated stylistic imitation could become infringing if it becomes "substantially similar" to the work of the original author. "We've never had a situation in which this personal style of individual creators could be imitated as well and as inexpensively as we now have with AI," George Washington University Law School Professor Robert Brauneis told Bloomberg Law.

  • Apple Will 'Watch Everything Burn' When AI Bubble Bursts
    by BeauHD on 27/07/2026 at 5:00 pm

    MacRumors interviewed AI critic Ed Zitron, author of the Where's Your Ed At newsletter and host of the Better Offline podcast, about what could happen to Apple if the costly AI infrastructure boom collapses. Zitron argued that Apple is relatively well insulated because it has spent far less on data centers than rivals such as Microsoft, Google, and Amazon. He said the company could use the downturn to make selective acquisitions, though it might simply continue operating largely as before. "I think they will sit on the sidelines and watch everything burn," Zitron said. Here's an excerpt from the report: If the bubble deflates the way you expect (write-downs, too much compute supply, possibly OpenAI cratering), can you walk us through what that would actually look like for Apple? Does anything break for iPhone users, or does Apple mostly watch it happen from the sidelines? Could it even benefit Apple? I think things would look much the same for Apple. I think they will sit on the sidelines and watch everything burn. I could see them doing some choice acquisitions as things begin to collapse, but I could also see them do nothing. I think Apple is in a very weird place at the moment. The Vision Pro was a dud, but it was also the most interesting and future-forward thing I've seen anyone put out in a while. If they were smart, they'd tread water and sink as much money into making that as small as humanely possible -- no matter how long it takes -- because the entire AI bubble is a result of everybody running out of hypergrowth ideas, mostly because we're flat out of new interfaces. I want to be clear that what they want to do with the Vision Pro requires it to basically be weightless and invisible and never need adjustments. When it works, it's genuinely awesome. But that's a load-bearing when. One slight movement means the whole thing goes out of focus. I can't even use mine anymore because it needs an update that requires you to wear the thing the whole time. So much promise, released too early, shoved out the door by a CEO on his way out.
