Since I didn't find this info on the site, I figured I would ask

I've been using WC/TC for years, and I don't recall it _ever_ crashing on me. Does anyone know what language was used to write it? Delphi?
I'd be curious also about Christian's bio, where he went to school, how he learned to develop, on what projects he also worked, advice he could give to new developers about writing solid software, etc.
Cheers
JD.
