A recent Slashdot article
discussed a mysterious letter
received by Fermilab containing what appeared to be a coded message.
Two enterprising cryptologists recently deciphered the message. Of the two, one posted the code used to decipher the message, written (as you might expect since you're reading it here) in Perl.
It's a nice snippet, and he earned even greater admiration from this humble monk for taking the care to use warnings and strict. It took him 29 lines, and was obviously written for clarity and not brevity. How many would it take you?
