K23: A Secure Research OS Running WASM - Jonas Kruckenberg

K23 offers a fresh look a OS design. It is entirely written in Rust with an integrated WASM JIT compiler that tries to answer what an OS built for the 21st century could look like. We will cover the general ideas behind K23 and its inspirations. We'll go over the project progress so far, and detail a few points that are of interest to the Rust crowd: various nightly features used, custom debugging tools, and a few stories from embedded Rust development.
