Ask HN: Which computer geek wrote a guide on dating for nerds?

I remember coming across a guide to dating written by some famous (or semi-famous) programmer some time ago. I think it was shared here, but I can't remember.

I know it had a humorous tone to it. Thought it would be a fun read but I never got around to it and now I can't find it. Hoping someone here knows what I'm talking about!
