>Sure I know what a NFA is, but ask me convert it to a DFA and I'm lost.

Do you really think your average HNer knows how to do that? Or even know what that means and how you define it? I really don't think so :)

In my opinion you know plenty about computer science, certainly much more than your average programmer, but I understand how you feel. I think of myself as not knowledgeable enough and below average all the time.

You haven't mentioned your goal. Do you want to eventually work in any of the areas you mentioned? Or rather you want to learn this for your own intellectual curiosity?
