Rust, the general purpose programming language developed by Mozilla for being a safe, concurrent, and practical language, can even be used to write a system kernel.
Rust has been around for a few years now though it's adoption hasn't been too widespread yet. For those unfamiliar with the language, visit Rust-Lang.org
The interesting project pointed out by a Phoronix reader today is Rustboot, a tiny 32-bit kernel written in Rust. This kernel can run within QEMU and is written entirely in Rust, but it doesn't do too much right now. As said in the project's read-me, "It paints the screen bright red and then hangs. That's it."
