larval stage
 n.

   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. See also
   {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.
