💥 Explore this awesome post from Hacker News 📖 📂 **Category**: ✅ **What You’ll Learn**: Posted July 7, 2026 It started with a Hacker News thread: LibreCAD, the whole Qt desktop application, compiled to WebAssembly and running in a tab. magik shipped that, then OpenSCAD, and the pattern looked like a recipe — Qt for WebAssembly, JSPI, a static dependency stack, and an honest audit of whatever the app assumed about threads, filesystems and OpenGL. The obvious next question was how far it scales. So here is FreeCAD: parametric 3D CAD, sketch-constrained solid modeling, an embedded Python, a dozen-plus workbenches.…

[Brown University] — Brown University chemists have provided direct evidence that upends the textbook explanation of how triple chemical bonds work in heavy elements. In a study published in Science, the researchers show evidence that when atomic nuclei are sufficiently heavy, the principles described in Einstein’s theory of relativity change the structure of triple bonds — blurring the lines between the two separate types of bonds involved in textbook triple bonding. Using a technique called photoelectron spectroscopy, the Brown team showed bonds created by…

💥 Explore this insightful post from Hacker News 📖 📂 **Category**: 💡 **What You’ll Learn**: Our last build-off hit the Hacker News front page, and the comments did not hold back.

Software Engineer – SDK at Moss

0 CommentsEntertainment

💥 Explore this must-read post from Hacker News 📖 📂 **Category**: 💡 **What You’ll Learn**: We built Moss because Voice AI breaks when retrieval is slow. Most retrieval infrastructure was not built for real-time reasoning. It adds latency, breaks context mid-conversation, and becomes the bottleneck just as an AI product needs to feel instant. Moss is the real-time semantic search layer for conversational AI. We deliver sub-10ms retrieval directly in the browser, at the edge, on-device, or in the cloud, without making teams stitch together a slow retrieval stack. We are backed by YC and run in production for teams…

✨ Discover this awesome post from Hacker News 📖 📂 **Category**: 💡 **What You’ll Learn**: Illustration by Aidan Roberts. Ever since James Cameron’s Terminator 2: Judgment Day was released in 1991, I’ve been reading about the many ways ILM, led by visual effects supervisor Dennis Muren, had to basically invent new ways to realise the CG ‘liquid metal’ T-1000 shots in that film, of which there are surprisingly few. Tools like ‘Make Sticky’ and ‘Body Sock’ are ones that I’d heard referenced several times, but I’ve always wanted to know more about how those pieces of software were made. So,…
