About

I'm Guillaume Petiot. I write here to work out what I think, and I publish it in case it is useful to someone else.

What connects most of what I write is an interest in how things work and, more often, how they fail: software, organisations, habits, and plans that looked sound on paper. I find that a failure usually explains more than a success does.

I started out in research, working on formal methods and the verification of software, which meant a good many years spent trying to prove that programs do what they are supposed to do. I now work in accounting, a profession I came to later in life, and I am still learning it. Outside work I like to build small things.

My earlier research is collected under Research.

What I am up to at the moment is on the Now page.
