Care to explain that one? And more interestingly; how you discovered it? )

`unpack "C", "f"` or `unpack "c", "f"` or `unpack "U", "f"` or `ord "f"` all give the character code of "f", which is 102. `unpack "H", "A"` gives "4", and you can replace the "A" with any other letter between "@" and "O". Thus, `unpack "HC", "Af"` returns ("4", 102). If you concatenate and reverse that list, you get "2014". From there, I just had to modify the strings until it gave something meaningful instead of random letters.	[reply] [d/l] [select]
