1. hexadecimal.

2. A 6-pack of anything (compare quad). Neither usage has anything to do with magic or black art, though the pun is appreciated and occasionally used by hackers. True story: As a joke, some hackers once offered some surplus ICs for sale to be worn as protective amulets against hostile magic. The chips were, of course, hex inverters.

3.   (character)   The hash character, used to introduce hexadecimal constants in some assembly languages.
