Bpftrace: A scriptable magnifying glass with X-ray vision for Linux

One of the posts that I link the article describes an environment used to make proctrace (https://github.com/zmitchell/proctrace), which includes both Rust and `bpftrace` for the tool itself, and some Node stuff for the documentation site.

For Rust development specifically it's a little more setup than without Flox because a typical `rustup` install gives you everything by default, whereas the Rust packages are distributed individually in the Flox Catalog (e.g. install `cargo` and `rustc` separately). That's due to how Nixpkgs packages Rust tools, and we'll probably provide a more ergonomic situation in the future. The only other real downside for Rust development is if you need to compile for a different target than the host machine e.g. wasm. You would need to write a flake that provides those toolchains and add that flake to your manifest.

That sounds like a lot of caveats and extra work, but that's because I’m long winded and have nothing else to really complain about. I have a Rust environment that I pushed to FloxHub, and then I pull a copy of it into each new project. I only needed to set it up once (which was easy) for it to work everywhere since it's reproducible and cross-platform by default.
