  • Rescue Mission Is Called Off For NASA's Aging Swift Space Telescope
    by BeauHD on 20/08/2026 at 7:00 am

    NASA has called off a $30 million mission to rescue its aging Swift space telescope after Katalyst Space's Link spacecraft developed persistent control and positioning problems. The Associated Press reports: Katalyst said Link will not attempt to capture Swift and boost it to a higher orbit because of problems with controlling the spacecraft. NASA said this means the telescope will plunge through the atmosphere after more than 20 years of tracking some of the biggest explosions in the universe like gamma ray bursts and exploding stars. Its demise is not expected before October. NASA paid $30 million to Katalyst in an attempt to raise the telescope to a safer, longer-lasting orbit. Intense solar activity caused it to lose altitude faster than expected. The rescue spacecraft went into an uncontrollable spin a few weeks after its liftoff in early July. While flight controllers managed to slow Link's tumble, issues continued to plague its pointing and positioning in orbit. "This is not the outcome we were working toward, but it does not change why this mission was worth attempting," NASA Administrator Jared Isaacman said in a statement. As a consolation prize, Katalyst will continue to operate Link in proximity with the telescope to demonstrate capabilities for future rescue operations. Katalyst CEO Ghonhee Lee said it was an ambitious mission on an aggressive timeline that was thrown together in under a year. "We took on this high-risk, high-reward challenge and are proud of the milestones we reached along the way," Lee said in a statement. "We have already learned a tremendous amount."

  • Whistleblower Arturo Bejar Leads Testimony In Landmark Trial Against Meta
    by BeauHD on 20/08/2026 at 3:30 am

    An anonymous reader quotes a report from NPR: Meta was infused with a culture in which employees obsessed over user numbers and consistently pushed safety to the side, according to Arturo Bejar, a former employee turned whistleblower, who testified today in the landmark child safety trial against the social media company. Only one man had the ability to change that, Bejar said: CEO Mark Zuckerberg. But he didn't. "At the end of the day, it was the company culture that Mark had created that made it so that it was practically impossible to deliver features that addressed the wellbeing and safety issues that we've been talking about," he said. Bejar is a linchpin witness for a consortium of states led by California, Colorado, Kentucky and New Jersey that sued Meta, alleging violations of consumer and child data protection laws, and that the company lied to the public about risks its platforms posed. The attorneys for the states say Meta designed Facebook and Instagram to hook young users and to keep them on site longer thanks to features such as infinite scrolling and the "like" button. Meta has denied the allegations. In his opening statement on Tuesday, attorney Paul Schmidt argued that the company was sensitive to the risks to teens, sought to address them and did not deceive the public about them. The state attorneys have not yet said if they will call Zuckerberg as a witness. Testifying in federal court in Oakland, California, for a second day on Wednesday, Bejar, who worked on safety issues at Meta for eight years, said he interacted with Zuckerberg dozens of times, and charged that Zuckerberg was not telling the truth when he made public denials that the company put profits over safety. In particular, Bejar addressed a widely-shared Facebook post Zuckerberg made in 2021 after another whistleblower, Frances Haugen, shared internal documents with The Wall Street Journal that highlighted risks to the mental health of teens. In the post, Zuckerberg said it's "just not true" that Meta prioritizes profit over safety and wellbeing. "Based on my experience at Meta, that is not an accurate statement," Bejar said. [...] Bejar testified, at almost every turn the company chose policies that boosted usership and revenue over safety. Safety was "not a meaningful priority," he said.

  • PINE64 Halts Linux Device Production Amid DRAM and EMMC Shortages
    by BeauHD on 19/08/2026 at 11:00 pm

    BrianFagioli writes: PINE64 has some very bad news for Linux hardware fans. PINE64 says it has no plans to produce additional Linux devices in the near future because of the ongoing DRAM and eMMC shortage. Future production will depend on component pricing after mid 2027, while existing PineNote and PineTab2 inventory could run out in roughly three months. The company says PineTime, PineVoice, and Pinecil production will continue as usual, but the outlook for its Linux hardware is much less certain. "That's it for this post, all in all it's a bit bleak for the Linux devices, but in the meantime PineStore still have a great lineup of MCU powered devices which will continue to expand with more exciting devices," the company said.

  • Stripe Buys AI Startup OpenRouter For $7.5 Billion
    by BeauHD on 19/08/2026 at 10:00 pm

    Stripe is acquiring AI model marketplace OpenRouter as it pushes beyond payments into the infrastructure behind AI applications. According to The New York Times, the deal is reportedly valued at about $7.5 billion, with $1.5 billion allocated to OpenRouter's founders. Less than three months ago the company was valued at about $1.3 billion. CNBC reports: OpenRouter has become popular with developers seeking to use AI models, particularly those considered non-proprietary and available for free. Many of these so-called open-weight AI models stem from Chinese labs like DeepSeek and Z.ai, which have gained steam among developers for generally being more cost-efficient relative to proprietary AI models from U.S. companies like OpenAI and Anthropic. In a blog post about the deal, Stripe noted that it's been working with companies to "optimize their token costs and route tokens efficiently," referring to a kind of metric used to measure AI model usage. Stripe said it's difficult to manage AI costs relative to performance because of the rapid "pace at which models are released and repriced." [...] OpenRouter said in a blog post that combining with Stripe will help with its overall vision of "a healthy AI ecosystem where many models thrive, where AI neurodiversity is a strength, where a lab or an inference provider with a breakthrough can reach millions of developers, and where no single model becomes the default by inertia." "Stripe is building the economic infrastructure for AI, and together with OpenRouter we'll help businesses maximize profitability by routing their requests intelligently and spending their tokens efficiently," Stripe CEO Patrick Collison said in a statement.

  • Amazon's Drones Will Soon Deliver to Nearly 500 US Cities and Towns
    by BeauHD on 19/08/2026 at 9:00 pm

    Amazon says its Prime Air drone delivery service will expand sixfold to nearly 500 U.S. cities and towns by the end of 2026, including metro areas around Chicago, Syracuse, Cleveland, Atlanta, and Boise. According to Amazon Prime Air vice president David Carbon, the service has already delivered "hundreds of thousands of packages to customers" this year, typically within about an hour. The Verge reports: These will join 11 locations across the US where Amazon already offers drone deliveries, with each Prime Air site serving an area of approximately 175 square miles. The service aims to quickly deliver packages of up to 5 pounds or less [...]. Amazon reiterated its drone safety features alongside these expansion plans, including Prime Air's "industry-leading Detect-and-Avoid system." That's likely an attempt to minimize any concerns raised by the communities where the service is expanding, given these drones have already been scrutinized for crashing into cranes, internet cables, gardens, and an apartment building.

  • Music Publisher Round Hill Files $1 Billion Copyright Infringement Suits Against Suno, Anthropic
    by BeauHD on 19/08/2026 at 8:00 pm

    Independent music publisher Round Hill is suing Suno and Anthropic for allegedly using hundreds of copyrighted songs without permission to train their AI systems. The company says potential damages could exceed $1 billion, arguing there is "nothing fair" about building multibillion-dollar AI businesses on copyrighted material while rights holders receive nothing. From The Hollywood Reporter: Round Hill is a prominent music publisher whose copyrights include the Goo Goo Dolls' "Iris," Bonnie Tyler's "Total Eclipse of the Heart," the Kinks' "Lola" and Dio's "Holy Diver." The company provided a list of 500 songs that the defendants had infringed upon. Round Hill said in the suits that the company plans to "amend to list potentially ten thousand or more of their musical compositions," with those damages potentially exceeding $1 billion. "While in other cases for copyright infringement, Defendant has waxed poetic about the necessity of progress and AI's value to society, there is simply no reason -- other than rote expediency -- to have that progress come at the cost of copyrights holders," prominent music attorney Richard Busch, representing Round Hill, wrote in the suits. Round Hill further argued that the latter "'expediency' arguments completely falter" when taking into account Suno and Anthropic's significant cash valuations they've earned while "exploiting illicit copies of copyrighted works, including the Round Hill Works." "There is simply nothing fair about a company using theft to build for purely commercial purposes a multi-billion dollar business while those from which they steal receive nothing," Round Hill said. Suno also faces a lawsuit from Universal Music Group and Sony Music Group. Read more of this story at Slashdot.
