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.
