Hi! I'm Amos. I write about how computers work - or at least, how they sometimes work. I write long pieces in a casual style, where we take our time to explore a problem. I tend to cover Rust a lot.

In my view, there's nothing that can't be explained if you're creative about it. And I enjoy doing that very much! I've made long series about reading files, the ICMP protocol, and I'm currently spending way too long talking about ELF executables.

Support me on Patreon, in exchange for my eternal gratitude, and/or early access.
