true-hacker
n.
[analogy with `trufan' from SF fandom] One who exemplifies the primary
values of hacker culture, esp. competence and helpfulness to other
hackers. A high compliment. "He spent 6 hours helping me bring up UUCP
and netnews on my FOOBAR 4000 last week -- manifestly the act of a
true-hacker." Compare {demigod}, oppose {munchkin}.
