noddy
 /nod'ee/, adj.

   [UK: from the children's books]

   1. Small and un-useful, but demonstrating a point. Noddy programs are
   often written by people learning a new language or system. The
   archetypal noddy program is {hello world}. Noddy code may be used to
   demonstrate a feature or bug of a compiler. May be used of real
   hardware or software to imply that it isn't worth using. "This
   editor's a bit noddy."

   2. A program that is more or less instant to produce. In this use, the
   term does not necessarily connote uselessness, but describes a {hack}
   sufficiently trivial that it can be written and debugged while
   carrying on (and during the space of) a normal conversation. "I'll
   just throw together a noddy {awk} script to dump all the first
   fields." In North America this might be called a {mickey mouse
   program}. See {toy program}.
