perfect programmer syndrome
n. Arrogance; the egotistical
conviction that one is above normal human error. Most frequently
found among programmers of some native ability but relatively
little experience (especially new graduates; their perceptions may
be distorted by a history of excellent performance at solving toy problems).
"Of course my program is correct, there is no need to
test it." "Yes, I can see there may be a problem here, but
I'll never type `rm -r /' while in root mode."
