Here is L-Packer, my new Atari & Amiga executable compressor! Optimized for 64K-style demos, it balances high compression ratios with efficient decompression. Feedback and testing are welcome! More details here github.com/arnaud-carre/L… #demoscene #amiga #atari

No need for software or IC :)

Use AI to train compressors on your specific data. Awesome!

Amazing work by such a tiny team! Btw the article has some great links to interactive digital design online simulator

I am pleased to share a small but valuable Unity feature I have been working on recently. It enables customization of certain visuals for each renderer at no additional CPU performance cost. discussions.unity.com/t/renderer-sha…

What can robotics learn from watch design? - Hundreds of parts packed into a coin-sized case, - keeping time within ±20 seconds daily - enduring decades of use Mechanical design at its most optimal. Let's explore the mechanisms that make watches tick ⬇️
