The simplest (not safest:) ) way of doing what you want is getting 5V switchable relays that basically turn on in the presence of 5V (really ~4) and turn off when seeing 0V.
Then hook up a pin from your parallel port to each of the relays, also hook up the ground pin to the control ground for the relay. You'll need a diagram of a parallel port from http://www.beyondlogic.org/index.html#PARALLEL or anywhere else to choose pins from the data byte. After that, turning on and off the relay is as simple (in linux) as getting perms to the port with ioperm (http://www.rt.com/man/ioperm.2.html) and making a bit go up or down in a certain byte in your memory space (the possible locations are in the parallel port doc above I believe).
I've done this, it's simple and it works... but don't mess up and put 120V through your parallel port. You will regret it:)
Well, if this was easy, codebreaking wouldn't be any fun. Don't forget that both the Germans and the Japanese had a variety (tens if not hundreds) of different cyphers in circulation, so it wasn't exactly as simple as assuming it's Enigma or Code Purple. As to how it's done, that has to do with analysing the text, frequency analysis of 1-grams 2-gram etc. Simple substitution will exhibit one fingerprint (though different languages will obviously be different), something like a playfair or Venegere (sp) square will have another, and DES encypted text a completely different structure. Obviously on a small enaugh sample there may not be enaugh information to latch into... But with a larger sample, it's mostly a combination of good tools, experience, and guesswork:)
Actually if you had taken _any_ economics classes you'd know that cutting costs is Exactly how capitalism works. A company's to maximize its profits by any means necessary. the key has always been a lot of very selfish interests working together to create Wealth and better Living Conditions. Anything else (government quality control and whatnot) is really leaning towards socialism. So call it what it is.

Which of course is the point. Why have everybody
pay more if we can just find those that will die
within five years of cancer by their genetic makeup. Let them pay for their own bad luck.
If anyone's missing this, that would be the basis
of all out genetic warfare between the genetic
haves and havenots.
And if you think you have good makeup, wait till
the engineered babies start apperaring, then we'll
all be in the same boat.
