I published online my 2 articles that have been published in Polish paper magazine "Programista" many years ago, in EN and PL version: - "Time Measurement in Game Programming" - "Writing Efficient C++ Code" Maybe a bit outdated, but maybe still useful? asawicki.info/news_1804_tw...

We are excited to announce that we can successfully use Rust's portable SIMD on the GPU. This has never been done before. www.vectorware.com/blog/simd-on... Supporting Rust's `core::simd` enables existing Rust code to work on the GPU and makes GPU programming more ergonomic.
Rust SIMD on the GPU
GPU code can now use Rust's portable SIMD. We share the implementation approach and what this unlocks for GPU programming.

New blog post! In "Zigzag decoding with AVX-512", we look at two different ways to possibly (caveat emptor) speed up various forms of zigzag decoding with AVX-512 functionality that isn't just "wider registers"! zeux.io/2026/06/17/z...
Zigzag decoding with AVX-512

A dream was always to make a "cloud" tool. Now over the last 1-2 years I tried to build smth on and off. Now I made it work in the browser. WARNING! Depending on the settings it can take a lot of GPU power, so be careful. Only for people who know what they're doing. artbuddy.urlich.ch/cloudbox/
