I've been designing, constructing, and debugging digital circuits since 1985 and doing the same with software since 1980. Sooner or later I might get good at it, but I've at least been able to make a living at it. I've been a contributor to English Wikipedia, under the same name, since 2001 (before there was a non-English Wikipedia) and have written some interesting stuff on my own site, which I will get back up soon. I'm deeply interested in the history of logic, electronics, materials science, and software, among other things, as you can see by my Wikipedia edits.
