A shallow survey of formal methods for C code
Two interesting things in formally verified software happened recently. The big one was the release of SeL4 - a formally verified L4 microkernel. The second was much smaller, but closer to my usual scope: a paper which showed the correctness of sections of a couple of the assembly implementations of Curve25519.

Implementing a safe garbage collector in Rust
In my last post I introduced an Emacs Lisp VM I was writing in Rust. My stated goal at the time was to complete a garbage collector.
