Long-time Slashdot reader schwit1 shared this report from Futurism: China has unveiled an extremely powerful "hypergravity machine" that can generate forces almost two thousand times stronger than Earth's regular gravity. The futuristic-looking machine, called CHIEF1900, was constructed at China's Centrifugal Hypergravity and Interdisciplinary Experiment Facility (CHIEF) at Zheijang University in Eastern China, and allows researchers to study how extreme forces affect various materials, plants, cells, or other structures, as the South China Morning Post reports... [Once up and running, it will allow researchers to recreate "catastrophic events such as dam failures and earthquakes inside a laboratory, according to the university."] For instance, it can analyze the structural stability of an almost 1,000-feet-tall dam by spinning a ten-foot model at 100 Gs, meaning 100 times the Earth's regular gravity. It could also be used to study the resonance frequencies of high-speed rail tracks, or how pollutants seep into soil over thousands of years. The machine officially dethroned its predecessor, CHIEF1300, which became the world's most powerful centrifuge a mere four months ago... It can generate 1,900 g-tonnes of force, or 1,900 times the Earth's gravity. To put that into perspective, a washing machine only reaches about two g-tonnes.

European satellite operator Eutelsat "plans to launch 440 Airbus-built LEO satellites in the coming years to replenish and expand its constellation," Reuters reported Friday. And last week America's Federal Communications Commission approved SpaceX's request to deploy another 7,500 Starlink satellites, while Starlink "projects it will eventually have a constellation of 34,000 satellites," writes Fast Company, and Amazon's Project Leo "plans to launch more than 3,200 satellites." Meanwhile "Beijing and some Chinese companies are planning two separate mega-constellations, Guowang and G60 Starlink, totaling nearly 26,000 satellites," and this week the Chinese government "applied for launch permits for 200,000 satellites." But a small Texas-based company called AST SpaceMobile "believes it can provide better service with fewer than 100 gigantic satellites in space." AST SpaceMobile has developed a direct-to-cell technology that utilizes large satellites called BlueBirds. These machines use thousands of antennas to deliver broadband coverage directly to standard mobile phones, says the company's president, Scott Wisniewski. "This approach is remarkably efficient: We can achieve global coverage with approximately 90 satellites, not thousands or even tens of thousands required by other systems," Wisniewski writes in an email... The key is its satellites' size and sophistication. AST's first generation of commercial satellite, the BlueBird 1-5, unfolds into a massive 693-square-foot array in space. Today, the company has five operational BlueBird 1-5 satellites in orbit, but its ambitions are much bigger. On December 24, 2025, AST launched the first of its next-generation satellites from India - called Block 2 - and this one broke records. The BlueBird 6 has a surface of almost 2,400 square feet, making it the largest single satellite in low Earth orbit. The company plans to launch up to 60 more by the end of 2026. "This large surface area is essential for gathering faint signals from standard, unmodified mobile phones on the ground," Wisniewski explains. It is essentially a single, extremely powerful and sensitive cell tower in the sky, capable of serving a huge geographical area... To be clear, AST SpaceMobile's approach is not without its own controversies. The sheer size of the company's satellites makes them incredibly bright in the night sky, a significant source of frustration for ground-based astronomers. McDowell confirms that when it launched in 2022, AST's prototype satellite, BlueWalker 3, became "one of the top 10 brightest objects in the night sky for a while." "It's a serious issue, and we are working directly with the astronomy community to mitigate our impact," Wisniewski says. The company is exploring solutions like anti-reflective coatings and operational adjustments to minimize the time its satellites are at maximum brightness... AST SpaceMobile has already proven its technology works, the article points out, with six working satellites now transmitting at typical 5G speeds directly to regular phones.

There's cursed computing, and then there's cursed computing. It turns out that you can render GNOME's windows with the compositor from Windows 7, dwm.exe. Yes. tl;dr of how this clusterfuck works: this is effectively just x11 forwarding an x server from windows to linux. the fun part is a) making gnome run with an already existing window manager (namely dwm.exe lol), b) making gnome run over x11 forwarding (it is Not a fan, last time it tried running gnome on windows this is what broke it and made it quit trying), and c) actually ripping out parts of the gnome compositor again to make dwm instead of gnome render window decorations to achieve ✨️aero gnome✨️ ↫ ⬡-49016 at Mastodon This is already one of the most cursed things I've ever seen, but then things got so much worse. How about Windows 7's dwm.exe, but composited by GNOME? I need an adult.

Virtualisation is a lot older than you might think, with (one of?) the first implementation(s) being IBM's VM/CMS, the line of operating systems that would grow to include things like System/370, System/390, all the way up until IBM/Z, which is still being developed and sold today; only recently IBM released the IBM z17 and z/OS 3.2, after all. The VM series of operating systems is designed exclusively for mainframes, and works by giving every user their own dedicated virtual machine running on top of the Control Program, the hypervisor. Inside this virtual machine the user can run a wide variety of operating systems, from the simple, single-user classics like IBM's Conversational Monitor System, to more complex systems like Linux or AIX. Early versions of VM were released as open source and are now in the public domain, and enthusiasts have continued to build upon it and expand it, with the latest incarnations being the VM/370 Community Edition releases. They contain the Control Program and Conversational Monitor System, augmented by various fixes, improvements, and other additions. You can run VM in an emulator like Hercules, and continue on from there - but what, exactly, can you do with it? That's where Fun things to do with your VM/370 machine comes in. This article will give you an introduction to the system, and a number of first and later steps you can take while exploring this probably alien environment. If you've always dreamt of using an early IBM mainframe, this is probably the easiest way to do so, because buying one is a really, really bad idea.

This week Google "unveiled a set of tools for retailers that helps them roll out AI agents," reports the Wall Street Journal, The new retail AI agents, which help shoppers find their desired items, provide customer support and let people order food at restaurants, are part of what Alphabet-owned Google calls Gemini Enterprise for Customer Experience. Major retailers, including home improvement giant Lowe's, the grocer Kroger and pizza chain Papa Johns say they are already using Google's tools to help prepare for the incoming wave of AI-assisted shopping and ordering... Kicking off the race among tech giants to get ahead of this shift, OpenAI released its Instant Checkout feature last fall, which lets users buy stuff directly through its chatbot ChatGPT. In January, Microsoft announced a similar checkout feature for its Copilot chatbot. Soon after OpenAI's release last year, Walmart said it would partner with OpenAI to let shoppers buy its products within ChatGPT. But that's just the beginning, reports the New York Times, with hundreds of start-ups also vying for the attention of retailers: There are A.I. start-ups that offer in-store cameras that can detect a customer's age or gender, robots that manage shelves on their own and headsets that give store workers access to product information in real time... The scramble to exploit artificial intelligence is happening across the retail spectrum, from the highest echelons of luxury goods to the most pragmatic of convenience stores. 7-Eleven said it was using conversational A.I. to hire staff at its convenience stores through an agent named Rita (Recruiting Individuals Through Automation). Executives said that they no longer had to worry about whether applicants would show up to interviews and that the system had reduced hiring time, which had taken two weeks, to less than three days. The article notes that at the National Retail Federation conference, other companies showing their AI advancements included Applebee's, IHOP, the Vitamin Shoppe, Urban Outfitters, Rag & Bone, Kendra Scott, Michael Kors and Philip Morris.

ChaosBSD is a fork of FreeBSD. It exists because upstream cannot, and should not, accept broken drivers, half-working hardware, vendor trash, or speculative hacks. We can. ↫ ChaosBSD GitHub page This is an excellent approach to testing drivers that simply aren't even remotely ready to be included in FreeBSD-proper. It should be obvious that this is not, in any way, meant to be used as a production operating system, as it will contain things that are broken and incomplete on purpose. The name's also pretty great.
