I'm a long-time user of free/open source software, and write various things for both fun and profit. I don't take myself all that seriously and I do all of my own stunts.
You can find me at these fine establishments on the web: Open Source Musings, The Monday Kickoff, Weekly Musings. and The Plain Text Project.

Geany got a mention in another roundup article, and has a good article devoted to it. It's gotten quite a bit of love, to be honest.
I don't program and, obviously, have never developed a hardware driver. Yet I've been using Linux as my sole operating system, and productively, since 1999.
