Funny how people tend to quote Linus Torvalds on technical issues in order to prove a point. I hear the guy barely made it through college.
Actually, I lied about even that. I was thrown out of fourth grade because I couldn’t write my own name, and it’s been all downhill from there. I had to lie about getting into college just so that I’d have better chances of making a career here at McDonalds - if you have a college degree (or you lied about having one), they don’t make you scrape the burger pans.

Something modular, where adding new components would be as easy as playing with Lego bricks.
