Tony Finch ☛ tolower() with AVX-512

A couple of years ago I wrote about tolower() in bulk at speed using SWAR tricks. A couple of days ago I was interested by Olivier Giniaux’s article about unsafe read beyond of death, an optimization for handling small strings with SIMD instructions, for a fast hash function written in Rust.

[Old] David Tran ☛ Checking If tmux Session Exists in Script

One thing I found cumbersome was that my script would rerun the commands even if the tmux session exists. This produced a session whose layout had additional panes, windows, etc. depending on the script.

Rust Blog ☛ The Rust Programming Language Blog: crates.io: development update

Since crates.io does not have releases in the classical sense, there are no release notes either. However, the crates.io team still wants to keep you all updated about the ongoing development of crates.io. This blog post is a summary of the most significant changes that we have made to crates.io in the past months.

When looking at crates like ripgrep you will notice that the installation instructions now say cargo install ripgrep instead of cargo add ripgrep. We implemented this change to make it easier for users to install crates that have binary targets. cargo add is still the correct command to use when adding a crate as a dependency to your project, but for binary-only crates like ripgrep, cargo install is the way to go.
