house wizard n.
[prob. 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 esp. of Unix wizards. The
term `house guru' is equivalent.
