computron: /kom'pyoo-tron`/ n. 1. A notional unit of computing
   power combining instruction speed and storage capacity, dimensioned
   roughly in instructions-per-second times megabytes-of-main-store
   times megabytes-of-mass-storage.  "That machine can't run GNU
   EMACS, it doesn't have enough computrons!"  This usage is usually
   found in metaphors that treat computing power as a fungible
   commodity good, like a crop yield or diesel horsepower.  See
   bitty box, Get a real computer!, toy, crank.
   2. A mythical subatomic particle that bears the unit quantity of
   computation or information, in much the same way that an electron
   bears one unit of electric charge (see also bogon).  An
   elaborate pseudo-scientific theory of computrons has been developed
   based on the physical fact that the molecules in a solid object
   move more rapidly as it is heated.  It is argued that an object
   melts because the molecules have lost their information about where
   they are supposed to be (that is, they have emitted computrons).
   This explains why computers get so hot and require air
   conditioning; they use up computrons.  Conversely, it should be
   possible to cool down an object by placing it in the path of a
   computron beam.  It is believed that this may also explain why
   machines that work at the factory fail in the computer room: the
   computrons there have been all used up by the other hardware.
   (This theory probably owes something to the "Warlock" stories
   by Larry Niven, the best known being "What Good is a Glass
   Dagger?", in which magic is fueled by an exhaustible natural
   resource called `mana'.)
