Yet Another useful paper

[Brian E Bradley]

  Documents released under the Freedom of Information Act reveal that,
starting in the late 1950's, the NSA was able to "read" the keyclicks
of a typist and know what was typed.

  There are a couple of dozen more tricks that even I, as a civilian, are
aware of.

  Let's face it: if someone is so eager to spy on you or break in that 
they're willing to spend lots of money on it, you probably can't prevent
it.  The best you can hope for is to catch them in the act and feed them
false or misleading information.

  But if your work is drab, boring, useless, or commonplace, rest easy:
they probably won't be interested.
