// About

A Linux nerd who never grew out of it.

I'm Brian. I write Go, I build operating systems, and I've spent thirty-some years convinced that the computer should work the way I think — not the other way around.

These days I manage engineers at Microsoft. Before that I was a cloud advocate, a startup CTO, a conference founder, and a co-author. The common thread is open source and a stubborn belief that systems should be legible. If you can't reason about it, you don't own it.

My favorite character is Duncan Idaho — killed, resurrected, and brought back across thousands of years. I relate. Every side project I've ever "finished" eventually comes back.
