I benchmark Ruby and graph the results, including at https://speed.yjit.org. I give talks about Ruby and programming. I write at https://codefol.io, where you can get on my email list for free chapters. I wrote Rebuilding Rails, Rebuilding HTTP and Mastering Software Technique.

I live in Inverness, Scotland with my wife, three kids, and two cats.
