Larval stage
Describes a period of monomaniacal concentration on coding apparently passed through by all fledgling hackers.
Common symptoms include the perpetration of more than one 36-hour
hacking run in a given week; neglect of all other activities including usual basics like food, sleep, and personal hygiene; and a chronic case of advanced bleary-eye.
Can last from 6 months to 2 years, the apparent median being around 18 months. A few so afflicted never resume a more "normal" life, but the ordeal seems to be necessary to produce really wizardly (as opposed to merely competent) programmers.

wannabee.
A less protracted and intense version of larval stage (typically lasting about a month) may recur when one is learning a new
OS or programming language.
