College Students

Why are they all so bad at programming?
This is my second semester at Uni and I am seriously helping seniors complete their idiotic Java programming assignments. It took me three fucking hours to explain one guy the difference between a compiler and an interpreter.

I thought Universities would be filled with programming geniuses, what the hell?

Haven't I mentioned it already, that LISP is a bad hobby? Ideally, your hobby should help you obtain social contacts and empower you in some way. So being a star wars fan or writing articles for some wiki are nice hobbies in all respects, but what gives you LISP, besides self-destructive tendencies?
