🤣 Data compression "gurus" are clutching their slide rulers in disbelief over a video that promises a magic trick to zip your files into oblivion. 🎩✨ Never mind the actual content—because who cares about those bytes when you can watch a blurry YouTube clip in SD quality, right? 📺💾

New blog series: @folkertdev shows how we use SIMD in the zlib-rs project.

SIMD is crucial to good performance, but learning how to use it can be daunting. In this series we'll show concrete examples of using SIMD in a real world project.

Part 1 explains how the compiler already uses SIMD for us, how to evaluate whether it's doing a good job, and how to use a more optimal version when the current CPU supports it.

For @trifectatech, Björn and Folkert created a Rust replacement for the bzip2 compression library, using c2rust to translate the C code. Read about the translation and cleanup experience in Folkert's blog: https://tweedegolf.nl/en/blog/151/translating-bzip2-with-c2rust
