Hello,
For security reasons I recommend computer chips are observed, tested, and "wave sampled" or so, and further analyzed to see if they are not leaking "too much" radio (electro?) (magnetic?) waves. (I am aware that they will do this anyway, but perhaps there are transmitters in their on purpose for spying purposes).
I have slight reason to believe that perhaps harddisks are secretly sending out radio electro magnetic waves from their chips and could therefore be observable.
For now take it with a grain of salt...
But you've been warned ! ;) =D
Bye, Skybuck.
