Screaming Penguin - Source Does Matter

Online book seller Amazon.com hosted a contest where a block of code was posted to be cracked; the winner recieving a whole bunch of cryptology books and materials. The code Amazon thought would take weeks to crack took only hours once news of the contest hit slashdot.org (why cant ToTSP have that kind of galvanizing effect??). Apparently the string of numbers seperated by hyphens turned out to be ISBN numbers (the numeric reference code on all books). Gee, Amazon themed it so appropriately.
