Same code, same input, different answer. A polygon-overlap test passed locally and failed on the server because LLVM folded a multiply-add into FMA on x86 and not on WASM. Here's a 2D geometry library that uses no floats — i64 coordinates, i128 cross products, bit-exact across architectures.
⚙️ Space Engineers just got a major update, Economy 2. The patch is FREE, and there's an optional paid Economy 2 Pack with decorative blocks.
The flagship is the Services Terminal: save whole grids (ships and bases) into a storage to free up PCU, restore them with precise placement via Precision Mode, perform quick repairs for in‑game currency and scrap unwanted builds. The economy got a serious redesign, the new Economy Overview merge...
@RcrdSgrd Could you tell more details about the device, name / type and hardware configuration (CPU, RAM, GPU, Screen Size).
I had simply more luck 😉 or did something different. Installation and running debian on different machines, new and old ones, from Dell (Desktops and Laptops), Lenovo (Desktops and Laptops), intel nuc (Desktop) and Terra (Laptop), Razer (Laptop) was without any problems.

Percatar: Awareness
El Modelo del Universo Sensible se construye en tres idiomas a la vez: griego, español e inglés. Cada uno aporta lo que los otros no tienen, y la metodología trilingüe — heredada del trabajo previo de Edith Stein y de las tradiciones contemplativas que han usado siempre más de una lengua.https://sensible-universe.com/2026/04/27/percatar-awareness/

96웰 플레이트에서 1나노리터~1마이크로리터 수준의 액체를 거의 완벽한 반복성으로 주입하는 실시간 로봇 시스템을 소개합니다. 미세한 규모에서도 흔들림, 드리프트, 과도한 오버슈트 없이 안정적으로 동작하는 점이 핵심입니다.
This is real time. You can see how stable the motion is. A system placing droplets between 1 nanoliter and 1 microliter inside a 96 well plate with almost perfect repeatability. No shake. No drift. No overshoot. The robot keeps the tip on track even at this scale where tiny
