... bright young men of disheveled appearance, often with
sunken glowing eyes, can be seen sitting at computer consoles,
their arms tensed and waiting to fire their fingers, already poised
to strike, at the buttons and keys on which their attention seems
to be riveted as a gambler’s on the rolling dice. When not so
transfixed, they often sit at tables strewn with computer printouts
over which they pore like possessed students of a cabbalistic
text. They work until they nearly drop, twenty, thirty hours
at a time. Their food, if they arrange it, is brought to them:
coffee, Cokes, sandwiches. If possible, they sleep on cots near
the printouts. Their rumpled clothes, their unwashed and
unshaven faces, and their uncombed hair all testify that they are
oblivious to their bodies and to the world in which they move.
These are computer bums, compulsive programmers ...
