  • Rapid Snow Melt-Off In American West Stuns Scientists
    by BeauHD on 02/04/2026 at 7:00 am

    Scientists say extreme March heat caused an unusually rapid collapse of snowpack across the American West that's leaving major basins at record or near-record lows. "This year is on a whole other level," said Dr Russ Schumacher, a Colorado State University climatologist. "Seeing this year so far below any of the other years we have data for is very concerning." The Guardian reports: [...] The issue is extremely widespread. Data from a branch of the US Department of Agriculture (USDA), which logs averages based on levels between 1991 and 2020, shows states across the south-west and intermountain west with eye-popping lows. The Great Basin had only 16% of average on Monday and the lower Colorado region, which includes most of Arizona and parts of Nevada, was at 10%. The Rio Grande, which covers parts of New Mexico, Texas and Colorado, was at 8%. "This year has the potential of being way worse than any of the years we have analogues for in the past," Schumacher said. Even with near-normal precipitation across most of the west, every major river basin across the region was grappling with snow drought when March began, according to federal analysts. Roughly 91% of stations reported below-median snow water equivalent, according to the last federal snow drought update compiled on March 8. Water managers and climate experts had been hopeful for a March miracle -- a strong cold storm that could set the region on the right track. Instead, a blistering heatwave unlike any recorded for this time of year baked the region and spurred a rapid melt-off. "March is often a big month for snowstorms," Schumacher said. "Instead of getting snow we would normally expect we got this unprecedented, way-off-the-scale warmth." More than 1,500 monthly high temperature records were broken in March and hundreds more tied. The event was "likely among the most statistically anomalous extreme heat events ever observed in the American south-west," climate scientist Daniel Swain said in an analysis posted this week. "Beyond the conspicuous 'weirdness' of it all," Swain added, "the most consequential impact of our record-shattering March heat will likely be the decimation of the water year 2025-26 snowpack across nearly all of the American west." Calling the toll left by the heat "nothing short of shocking," Swain noted that California was tied for its worst mountain snowpack value on record. While the highest elevations are still coated in white, "lower slopes are now completely bare nearly statewide." Read more of this story at Slashdot.

  • SpaceX Files To Go Public
    by BeauHD on 02/04/2026 at 3:30 am

    Reuters reports that SpaceX has confidentially filed for a U.S. IPO, reportedly targeting a valuation above $1.75 trillion. Reuters reports: SpaceX puts more rockets in space than any other company and promises a chance to invest in humanity's return to the moon and attempt to colonize Mars. The company aspires to put artificial intelligence data centers in space, while running a lucrative satellite communications system that opens up much of the earth to the internet and is increasingly used in war. [...] A public listing at a potential valuation of more than $1.75 trillion comes after SpaceX merged with Musk's artificial intelligence startup xAI in a deal that valued the rocket company at $1 trillion and the developer of the Grok chatbot at $250 billion. SpaceX is hosting an analyst day on April 21, encouraging research analysts to attend in person, [...]. The company is also offering analysts an optional visit to xAI's "Macrohard" data center site in Memphis, Tennessee, on April 23, and plans to hold a virtual session on May 4 to discuss financial models with banks' research analysts, the source said.

  • NASA Launches Artemis II Astronauts Around the Moon
    by BeauHD on 01/04/2026 at 11:00 pm

    NASA's Artemis II mission has launched four astronauts around the moon and back, marking humanity's first crewed lunar voyage in 53 years and the first test flight of NASA's Orion capsule and Space Launch System (SLS) with people on board. Five minutes into the flight, Commander Reid Wiseman saw the team's target: "We have a beautiful moonrise, we're headed right at it," he said from the capsule. The Associated Press reports: Artemis II set sail from the same Florida launch site that sent Apollo's explorers to the moon so long ago. The handful still alive cheered this next generation's grand adventure as the Space Launch System rocket thundered into the early evening sky, a nearly full moon beckoning some 248,000 miles (400,000 kilometers) away. Artemis II commander Reid Wiseman led the charge into space with "Let's go to the moon!" accompanied by pilot Victor Glover, Christina Koch and Canada's Jeremy Hansen. It was the most diverse lunar crew ever with the first woman, person of color and non-U.S. citizen riding in NASA's new Orion capsule. Carrying three Americans and one Canadian, the 32-story rocket rose from NASA's Kennedy Space Center where tens of thousands gathered to witness the dawn of this new era. Crowds also jammed the surrounding roads and beaches, reminiscent of the Apollo moonshots in the 1960s and '70s. It is NASA's biggest step yet toward establishing a permanent lunar presence.

  • UFC-Que Choisir Takes Ubisoft To French Court Over the Crew Shutdown
    by BeauHD on 01/04/2026 at 10:00 pm

    Longtime Slashdot reader Elektroschock writes: When Ubisoft pulled the plug on The Crew's servers without warning, players were left with a worthless game they'd already paid for. Now, consumer watchdog UFC-Que Choisir is fighting back, demanding gamers' right to play regardless of publisher whims. Supported by the "Stop Killing Games" movement, this landmark case challenges unfair terms before the Creteil Judicial Court (Val-de-Marne near Paris), and aims to protect players from disappearing games. The lawsuit that UFC-Que Choisir filed against Ubisoft on Tuesday alleges that the video game publisher "misled consumers about the permanence of their purchase and imposed abusive contractual clauses stripping players of ownership rights," reports Reuters.

  • AI Can Clone Open-Source Software In Minutes
    by BeauHD on 01/04/2026 at 9:00 pm

    ZipNada writes: Two software researchers recently demonstrated how modern AI tools can reproduce entire open-source projects, creating proprietary versions that appear both functional and legally distinct. The partly-satirical demonstration shows how quickly artificial intelligence can blur long-standing boundaries between coding innovation, copyright law, and the open-source principles that underpin much of the modern internet. In their presentation, Dylan Ayrey, founder of Truffle Security, and Mike Nolan, a software architect with the UN Development Program, introduced a tool they call malus.sh. For a small fee, the service can "recreate any open-source project," generating what its website describes as "legally distinct code with corporate-friendly licensing. No attribution. No copyleft. No problems." It's a test case in how intellectual property law -- still rooted in 19th-century precedent -- collides with 21st-century automation. Since the US Supreme Court's Baker v. Selden ruling, copyright has been understood to guard expression, not ideas. That boundary gave rise to clean-room design, a method by which engineers reverse-engineer systems without accessing the original source code. Phoenix Technologies famously used the technique to build its version of the PC BIOS during the 1980s. Ayrey and Nolan's experiment shows how AI can perform a clean-room process in minutes rather than months. But faster doesn't necessarily mean fair. Traditional clean-room efforts required human teams to document and replicate functionality -- a process that demanded both legal oversight and significant labor. By contrast, an AI-mediated "clean room" can be invoked through a few prompts, raising questions about whether such replication still counts as fair use or independent creation.

  • Cloudflare Announces EmDash As Open-Source 'Spiritual Successor' To WordPress
    by BeauHD on 01/04/2026 at 8:00 pm

    In classic Cloudflare fashion, the CDN provider used April Fool's Day to unveil an actual, "not a joke" product. Today, the company announced EmDash -- an open-source "spiritual successor" to WordPress that aims to solve plugin security. Phoronix reports: With the help of AI coding agents, Cloudflare engineers have been rebuilding the WordPress open-source project "from the ground up." EmDash is written entirely in TypeScript and is a server-less design. Making plug-ins more secure than the WordPress architecture, EmDash plug-ins are sandboxed and run in their own isolate. EmDash builds upon the Astro web framework. EmDash doesn't rely on any WordPress code but is designed to be compatible with WordPress functionality. EmDash is open-source now under the MIT license. The EmDash code is available on GitHub. Read more of this story at Slashdot.
