hex
     
        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.  The {hash} character, used to introduce
        {hexadecimal} constants in some {assembly language}s.
