Words that can be rendered in HEX

December 15, 2007

If you’re in IT, or just like to hack around with computers, you invariably run into HEX numbers. About the only fun thing with HEX is that since it uses the letters A-F, you can use it to write out words. 0xDEADBABE, 0xDEADBEEF, 0xBABECAFE, 0xDECAFBAD, and 0xDEFEC8ED (defecated) are the standard ones that come to mind.

You can use this command

egrep "^([a-fo]|ate|to|too|two|for|four)\*$" /usr/share/dict/words

to print out a list of words on a *NIX system that can be rendered in HEX using ‘0’ for ‘o’, ‘8’ for ‘ate’, ‘2’ for ‘to’/’too’/’two’, and 4 for ‘for’/’four’. On Mac OS X 10.5 (Leopard), the above command finds the following ‘words’:
