The word "Hacker" can mean several things. It can mean a computer intruder, in which case, see the question above - I am certainly not one. Otherwise, it can mean a clever and competent enthusiast of a certain field of endeavour, primarily used by and for computer workers, but not exclusive to them. As I note, by inspiration from other sources, hacking is at least several millennia old.

Anyway, a "hacker" is something that normally other people call you rather than something you call yourself. I aspire for excellence and continuous improvement in several fields of endeavour (including software development), but only other people can judge whether I am indeed a hacker of them. And my policy is to encourage criticism rather than fanboy/fangirl-ism.
