Just ran a quick benchmark comparing different hashing functions on a Zen 5 EPYC processor (in pure Rust, from https://github.com/rust-stdx/stdx), and Ho My G...! BLAKE3 is crazy fast!

13 GB/s!

Announcing stdx, Rust's extended standard library.

Inspired by Go's extensive standard library and `golang.org/x/...` packages, the goal is to bring simplicity, performance and supply chain security to every Rust developer.

While a few people are complaining that AI is "stealing Open Source", training on Open Source code and giving nothing in return, the complete opposite is true, we are in the golden age of Open Source and you should surf the wave until it crashes.

An essential part of being able to say "I told you so" is in fact having told you so.

Well, here is how the next supply chain attack on #rust will be carried out: https://kerkour.com/rust-supply-chain-nightmare

A 10x performance boost for less that half a day of work?

#rust makes it easy thanks to SIMD intrinsics.

Here are the lessons we've learned implementing SIMD-accelerated algorithms for all platforms (AVX2, AVX-512, NEON and #webassembly SIMD128)
