You're making a false (and grossly unfair) generalization from the character of network programmer Dennis Nedry in "Jurassic Park".
The folks I work with in SystemAdmin/IT represent a range of personalities, body types, etc. but none who match that characterization.
I'm sure there are some somewhere that do, but your comment is nothing more than gratuitous slander. Stow it, please; crap comments like that demean this forum.
Get over yourself. What is that smell?
