  • 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."

  • FDA Approves First Alzheimer's Blood Test For Americans As Young As 40
    by BeauHD on 24/08/2026 at 5:00 pm

    The FDA has cleared the first Alzheimer's blood test for symptomatic patients as young as 40. The test measures amyloid and tau biomarkers from a single blood draw and identified positive biomarkers with 97.6% accuracy in a validation study. New Atlas reports: PrecivityAD2 is a single blood test that quickly assesses the proteins amyloid and tau, using mass spectrometry to measure plasma AB42/40 and p-tau217/np-tau217. The results are then scored, qualifying as negative, likely positive, or positive for AD. "Just over a year ago, there were no FDA-cleared blood tests for Alzheimer's, and now we have three," Isobel Coleman, chief executive officer of the Alzheimer's Drug Discovery Foundation (ADDF), said in a statement. "This is a proof point that sustained, early investment in translational science plays a catalytic role in moving promising ideas from the lab to patients." In a recent clinical validation study, 1,142 symptomatic adults were tested using PrecivityAD2. The process accurately identified 97.6% of positive biomarkers. What's more, the results remained consistent even in patients with comorbidities like chronic kidney disease and diabetes, which can distort plasma amyloid samples. It's worth noting that the test isn't intended for general health screenings, but for patients who already show some cognitive decline. "As PrecivityAD2 and tools like it move further into clinical practice, they will enable earlier detection, sharpen clinical trials, and build the foundation for precision medicine and combination therapies," Coleman added.

  • Humanoid Robots Run 100 Meters Faster Than Usain Bolt's Record Pace
    by BeauHD on 24/08/2026 at 4:00 pm

    Two humanoid robots competing at the World Humanoid Robot Games in Beijing on Saturday ran the 100-meter dash faster than Usain Bolt's 9.58-second world-record time. "[T]he Tiangong Ultra humanoid robot completed the 100-meter dash in 9.39 seconds during a preliminary heat," reports Engadget. "Developed by Beijing Humanoid Robot Innovation Center, the record-holding robot overtook Honor's Lightning robot, which completed the sprint in 9.47 seconds. From the report: Despite the impressive finish times, don't expect these humanoid robots to be used for any commercial purposes yet. After their sprints, they slammed directly into pads and some even required human assistance to be stretchered off the course. However, it's still a major improvement from last year's inaugural World Humanoid Robot Games, where the Tiangong Ultra won the 100-meter dash in 21.5 seconds. Beijing has also hosted a humanoid robot half-marathon, where Honor's Lightning won in 50 minutes and 26 seconds, which also beat the pace of another human world record. "The World Humanoid Robot Games in Beijing kicked off August 22 and will run until the 26, hosting thousands of robot participants competing in more than just track and field events, including soccer, table tennis and boxing," adds Engadget.

  • Dr. Dre Says He Uses AI To Produce Songs
    by BeauHD on 24/08/2026 at 3:00 pm

    An anonymous reader quotes a report from Gizmodo: Dr. Dre, the pioneering rapper and seven-time Grammy-winning producer behind hit songs like Tupac's "California Love" and Eminem's "The Real Slim Shady," is very much pro using artificial intelligence tools to make music. In an interview with the New York Times, Dr. Dre and Interscope Records co-founder Jimmy Iovine spoke about artificial intelligence's recent foray into music production, with the producer characterizing those who oppose AI song generation tools as "afraid of learning new things." "I don't see it as a threat. I think the only people that see it as a threat are the people who have trouble creating," Dr. Dre said. "I had a discussion with a few people a few days ago. They were against AI, and I'm like, 'OK, you sound like the person that would have been against the drum machine when it came out.' Or synthesizers, right?" [...] Iovine, the music executive and Dr. Dre's partner in Beats by Dre, for his part, says he doesn't "see the downside at all." "There will be some crappy music. There's crappy music now," Iovine told the NYT. "In the studio, when gifted people have AI, they're going to make better records." Dr. Dre said he uses AI in producing "as a tool to see what it would do with what I just did." The award-winning producer also said he is definitely not alone among his peers in his stance on AI either: many producers use AI but fear to admit it. Iovine calls them "closet AI producers," and says Timbaland, the four-time Grammy-winning singer-producer behind a long list of hits like "Promiscuous" with Nelly Furtado, is also one.
