The Jargon File (version 4.4.7, 29 Dec 2003):
uninteresting
 adj.
    1. Said of a problem that, although nontrivial, can be solved simply by
    throwing sufficient resources at it.
    2. Also said of problems for which a solution would neither advance the
    state of the art nor be fun to design and code.
    Hackers regard uninteresting problems as intolerable wastes of time, to be
    solved (if at all) by lesser mortals. Real hackers (see toolsmith)
    generalize uninteresting problems enough to make them interesting and solve
    them ? thus solving the original problem as a special case (and, it must be
    admitted, occasionally turning a molehill into a mountain, or a mountain
    into a tectonic plate). See WOMBAT, SMOP; compare toy problem, oppose
    interesting.
