A fascinating hacker story I barely understand.

An ingenious fellow has decoded the software in an iPod by converting that code into sounds, played through the iPod's headphone jack like a piece of music. He placed a microphone and the iPod in a padded box, recorded these sounds, and then converted them to computer code. This acoustic hack is much like the old acoustic coupler kind of modem, which I'm sure many of you don't remember. There's a lesson to be learned here about having deeper understanding and knowing history to solve today's problems.
