Tim Arnold

I’ve been writing software for about twenty-five years, most of it in Python and a surprising amount of it around the guts of documents — PDF, LaTeX, XML. It’s a stranger specialty than it sounds, and I’ve never really wanted to stop.

I wrote the second edition of Black Hat Python, and I turn up at security conferences now and then. The rest of the time I’m making pictures: crystals under a microscope, curves drawn by arithmetic, and some sheets of folded colour.

Writing on one side, pictures on the other. Go wherever you like.
