  • Amazon Hikes Hardware Prices By 60%, Blaming Memory Shortage
    by BeauHD on 24/08/2026 at 11:00 pm

    Amazon has raised the prices of its hardware devices by as much as 60%, blaming "significant increases in memory and storage component costs." TechCrunch reports: The price explosion impacted Fire TVs, Echos, Kindles, and Eeros. One egregious example that's been cited is that of the Echo Dot, one of Amazon's cheapest smart speakers, the price of which jumped 60% overnight, from $49.99 to $79.99. Price-tracking sites like CamelCamelCamel show the stark uptick, which has previously hovered much lower. [...] The company also said that it would continue to offer occasional promotions to customers over the course of the next year. Amazon said in a statement: "The consumer electronics industry is facing significant increases in memory and storage component costs. After absorbing these increases for as long as we could, we recently adjusted pricing across our product lines." Read more of this story at Slashdot.

  • SEC Investigating Near-Implosion of AI Hedge Fund
    by BeauHD on 24/08/2026 at 10:00 pm

    The SEC is investigating the near-collapse of AI-focused hedge fund Situational Awareness, sending subpoenas to major Wall Street banks for details about the fund's trades, borrowing, and communications with lenders. The fund, founded by former OpenAI researcher Leopold Aschenbrenner, managed over $30 billion and borrowed tens of billions more before leveraged bets unraveled, forcing it to sell most of its stock portfolio to Citadel at a discount. The New York Times reports: The subpoenas asked for details on the timing of Situational Awareness's trades and for its communications with lenders about the money it was borrowing, also known as "leverage," two of those people said. The subpoenas additionally warned the banks to preserve any information regarding the San Francisco hedge fund. The S.E.C. oversees financial markets with an eye toward protecting small investors, and has brought civil cases regularly against investment firms that produced large losses. Any investigation into Situational Awareness would be at its earliest stages, and it's no guarantee that it would lead to fines or other punishment. The hedge fund has not been accused of wrongdoing. [...] Situational Awareness had a fast rise and an even quicker retreat. Founded just two years ago by Leopold Aschenbrenner, a former researcher at OpenAI, it rode the A.I. boom to soaring investment returns. To achieve those results, however, the fund relied on heavy borrowing, as well as complicated and expensive financial instruments that magnify gains -- and losses. The latter piled up quickly last month when the stock prices of publicly traded, high-flying A.I. companies dipped. At the same time, shares in more traditional technology companies -- which the hedge fund had been betting against -- rose, compounding the problem. Situational Awareness was forced into a fire sale. It wound up selling most of its stock portfolio to a rival, Citadel, at a discount. Read more of this story at Slashdot.

  • Trump Admin Moves to Impose More Than $100K Fee For H-1B Worker Visas
    by BeauHD on 24/08/2026 at 9:00 pm

    The Trump administration is proposing to make permanent a $103,265 fee on certain new H-1B visas, dramatically increasing costs for employers that rely on highly skilled foreign workers in tech, education, and research. "A federal judge in June ruled that the fee was illegal and blocked the Trump administration from collecting it," reports Reuters. "A Boston-based appeals court is reviewing that decision while a different court considers whether a judge properly rejected a challenge to the fee by a major business group." From the report: Trump's temporary fee increase expires in September, one year after it was issued. The proposed rule by the U.S. Department of Homeland Security, posted in the Federal Register on Monday, would make a fee of $103,265 permanent. It could be finalized by the end of the year. The H-1B program allows U.S. employers to hire foreign workers with training in specialty fields and offers 65,000 visas annually, with another 20,000 for workers with advanced degrees, approved for three to six years. Those visas typically came with fees between $2,000 and $5,000 before Trump's order. The fee would not apply to visas granted to foreign citizens already in the United States on student visas, who make up a large share of new H-1B recipients, or to renewals of current visas.

  • Raspberry Pi Shares Its Official Tutorial For Making a Cyberdeck
    by BeauHD on 24/08/2026 at 8:00 pm

    Raspberry Pi has published an official guide for building a cyberdeck, leaning into a viral trend of homemade portable computers built from repurposed cases, purses, and other oddball hardware. The guide uses a Raspberry Pi 5, keyboard, battery, and Pelican-style case. The Verge reports: Raspberry Pi's head of social, Ashley Whittaker, acknowledged the cyberdeck trend today, saying "we haven't been able to get away from cyberdecks this year." Raspberry Pi has also increased its prices multiple times this year due to rising costs for RAM and other components, which could be another reason to support this growing market of active and would-be hobbyists. The 16GB version of the Raspberry Pi 5 included in the company's official cyberdeck guide got a $100 price hike in April, nearly as much as the board's original $120 price.

  • Nvidia Senior Manager Linked To Supermicro Scheme Smuggling AI Servers To China
    by BeauHD on 24/08/2026 at 7:00 pm

    An anonymous reader quotes a report from Ars Technica: Taiwan has indicted nine people -- reportedly including an Nvidia senior manager and two Supermicro employees based in the country -- who allegedly helped forge documents to cover up illegal exports of high-end AI servers to China in violation of US export controls. On Monday, Reuters reported that prosecutors in Keelung did not release any names but confirmed that the suspects were "charged with breach of trust and document forgery." One suspect linked to a related case remains at large, accused of the "siphoning of funds from a distributor company involved" in helping China get access to restricted Nvidia chips. Since 2022, the US has required a license to export semiconductors to China, with the intent of protecting national security by staying ahead of China in the AI race. But after the US arrested Supermicro co-founder Wally Liaw in March for allegedly funneling $2.5 billion in restricted AI servers to China since 2024, Taiwan launched a separate probe to learn more about the scheme. Taiwan's investigation found that co-conspirators attempted to falsify documents to make it appear that 130 B300 servers were installed and in use at a Taiwan facility. But 74 of those servers "were ultimately exported and delivered to Chinese customers," Reuters reported, while the rest, 56, were intended to go to China but were blocked once Taiwanese customs officials "detected irregularities." According to Taiwan officials, Nvidia's manager and Supermicro employees "colluded with one another at various levels for enormous profit, illegally exporting high-end servers, increasing corporate compliance costs, and severely damaging our nation's international image." Supermicro said in a statement to PCMag: "Supermicro is committed to protecting our advanced technologies and intellectual property. We are working closely with Taiwanese authorities on recent events, which underscore the importance of continued collaboration across industry and government to strengthen safeguards, enhance supply chain visibility, and facilitate the enforcement of export control laws."

  • China Delays Ambitious Chang'e 7 Lunar Mission Until 2027
    by BeauHD on 24/08/2026 at 6:00 pm

    China has delayed its ambitious Chang'e 7 lunar mission until at least 2027 after scrubbing an August 24 launch. Poor weather conditions were likely a factor, with China's Manned Space Agency (CMSA) saying the decision reflects the need for "absolute safety." Scientific American reports: China and the U.S. are in a race to send humans back to the moon, a feat that that U.S. accomplished in the 1960s and that has never been achieved by any other country. Chang'e 7 is to play to a crucial part in China's ambitions: the probe is designed to search for frozen water in the Shackleton Crater, a pit that spans some 21 kilometers (13 miles) and sits beside the lunar south pole. No spacecraft has ever landed in that region, which scientists consider to be among the likeliest places to find water on the moon. Locating water that can be used by humans is vital to establishing any long-term lunar presence. NASA and China are eyeing the region to establish a crewed base -- and because this real estate is so precious, it matters who gets their first. Ars Technica notes in its reporting that the delayed launch was "most likely" due to Typhoon Narra, "which has 45 mph winds (equivalent to a moderate Tropical Storm) and continues to meander around in the waterway separating Hainan Island, where the spaceport is located, and mainland China." As for why the next launch window won't open until next February or March? "It likely is a combination of factors, including sunlight conditions in polar landing zones as well as the mission plan that requires a 90-day lunar orbit reconnaissance before landing," reports Ars. There's also a possibility, albeit an unlikely one, that "some technical issue was discovered at the last minute with either the complex Chang'e 7 payload, or the rocket."
