: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}.
