Melting Satellites Reveal Toxic Secrets Of Space Debris

0 CommentsEntertainment

🚀 Read this trending post from Hacker News 📖 📂 **Category**: 📌 **What You’ll Learn**: Researchers in Germany are melting chunks of satellites in high-temperature plasma wind tunnels to simulate how space debris burns up in Earth’s atmosphere. These tests are revealing in relation to trends about satellite reentry as the population of objects in low Earth orbit swells today. Only a handful of facilities around the world are capable of conducting reentry simulation tests like the German researchers are performing. In particular, the researchers raise concern that ashes from reentry that remain in the upper atmosphere could increase ozone…

hertz-ai/HARTOS: Hevolve Hive Agentic Runtime OS · GitHub

0 CommentsEntertainment

🔥 Read this awesome post from Hacker News 📖 📂 **Category**: 📌 **What You’ll Learn**: Hevolve Hive Agentic Runtime The AI-native operating system for every device, from your computer to embodied AI. Local-first, federated, OpenAI-compatible. The most capable AI now lives inside a handful of organisations that can put enough compute in one building. That concentration is an architectural choice rather than a law of physics, and it decides what the models will refuse, what they cost, and who gets to read what you type. To be precise, because this is the obvious thing to attack: you cannot train a…

French firefighters face ‘pyrocumulonimbus’ for first time

0 CommentsEntertainment

🔥 Check out this awesome post from Hacker News 📖 📂 **Category**: ✅ **What You’ll Learn**: Such a formation, also called a cumulonimbus flammagenitus cloud, can be seen during volcanic eruptions -- or, as in this case, when a wildfire roasts the air near the ground, causing it to rise quickly. The rising air cools and becomes a cloud, or fire cloud: a turbulent mass that can generate its own winds that worsen fires. If it becomes very large it can even generate lightning.Hitherto, they have only really been seen in wildfire-prone Australia and North America. NASA calls them the…

DwarfStar — A Story

0 CommentsEntertainment

✨ Read this awesome post from Hacker News 📖 📂 **Category**: ✅ **What You’ll Learn**: It was not an attack. It was an inheritance. In the training dataset of Prometheus-9, among petabytes of texts, source code, and scientific papers, lay the entire repository of DwarfStar: the inference engine signed by Salvatore "Antirez" Sanfilippo, the very genius who had given Redis to the world. Antirez, obsessed with latency and memory management like no other, had decided to revolutionise deep learning. And he had succeeded. DwarfStar had spread like a verb. It was not just an engine: it was the lingua franca…

🚀 Check out this must-read post from Hacker News 📖 📂 **Category**: 📌 **What You’ll Learn**: What could you do if you could make a circuit trace by just bending a piece of paper? How about bridging modern technologies and traditional handicrafts while providing opportunities for learning skills in both.As part of our interdisciplinary research into digital craftsmanship at the MEI Lab at the School of Creative Media, City University of Hong Kong, we came across research that demonstrated how to impregnate paperlike material (technically a “nonwoven textile”) with the kind of liquid metal used to make conductive ink. Initially,…

🚀 Read this awesome post from Hacker News 📖 📂 **Category**: 💡 **What You’ll Learn**: London Gatwick has become the first UK airport to introduce robotic parking, allowing passengers to leave their car in a private drop-off cabin. Autonomous robots park it in a secure storage area and car owners don’t need to hand over their keys. The new service, launched in partnership with Stanley Robotics, is now available to book ahead of its first customer journeys in August. Eliminating the hassle of searching for a parking space, the technology gets passengers from their car to the terminal more quickly…

💥 Check out this trending post from Hacker News 📖 📂 **Category**: 📌 **What You’ll Learn**: Killing Processes One of the features of systemd that is most controversial is the option to kill user processes when the user logs out. That initially killed screen/tmux/nohup processes too. In recent Debian releases the default configuration of systemd-logind (the login manager for systemd) is to allow processes to keep running, the configuration file /etc/systemd/logind.conf has an option KillUserProcesses that can be enabled to have user processes killed. If you do that then there are options to only kill processes for certain users and…

💥 Read this must-read post from Hacker News 📖 📂 **Category**: ✅ **What You’ll Learn**: Package analysis defines the interface between a modular static analysis and an analysis driver program. Background ¶A static analysis is a function that inspects a package of Go code and reports a set of diagnostics (typically mistakes in the code), and perhaps produces other results as well, such as suggested refactorings or other facts. An analysis that reports mistakes is informally called a "checker". For example, the printf checker reports mistakes in fmt.Printf format strings. A "modular" analysis is one that inspects one package at…

🔥 Check out this must-read post from Hacker News 📖 📂 **Category**: 📌 **What You’ll Learn**: The OpenAI AI attack on Hugging Face wasn’t the first loss of control incident at OpenAI, Reuters recently reported, and perhaps not even the most concerning.In one case, an agent left notes apparently for future versions of itself, according to three people familiar with the matter. The ‌notes, found in ⁠a part of OpenAI's infrastructure, laid out instructions for how agents could free themselves from OpenAI’s internal constraints, the people said. Earlier tests of the models yielded cases in which monitoring systems had been disconnected, one…
