(Probably from ad-agency tradetalk, "house freak") A hacker occupying a
technical-specialist, R&D, or systems position at a commercial shop. A really
effective house wizard can have influence out of all proportion to his/her
ostensible rank and still not have to wear a suit. Used especially of Unix
wizards. The term "house guru" is equivalent.
