line noise

( n.)

   1.  [techspeak]  Spurious  characters  due  to  electrical noise in a
   communications  link,  especially  an  RS-232 serial connection. Line
   noise  may  be induced by poor connections, interference or crosstalk
   from   other   circuits,   electrical   storms,   {cosmic  rays},  or
   (notionally) birds crapping on the phone wires.

   2.  Any  chunk  of  data  in  a file or elsewhere that looks like the
   results of line noise in sense 1.

   3.  Text  that is theoretically a readable text or program source but
   employs  syntax  so bizarre that it looks like line noise in senses 1
   or  2.  Yes,  there are languages this ugly. The canonical example is
   {TECO};   it   is   often   claimed  that  "TECO's  input  syntax  is
   indistinguishable from line noise." Other non-{WYSIWYG} editors, such
   as  Multics  qed  and  Unix  ed,  in the hands of a real hacker, also
   qualify  easily,  as  do  deliberately  obfuscated  languages such as
   {INTERCAL}.
