At yesterday's BALUG meeting, someone hauled out an old chestnut:
There are 10 types of people in this world, those who understand binary and those who don't. -- Unknown
I mentioned that there were a couple of responses to that, that I had converted to .signature files. The first was by a poster named Ron Fabre on the Linux Users of Victoria (Melbourne) mailing list (whose comment I .sigged):
-- Cheers, There are 10 kinds of people in the world, those who Rick Moen know ternary, those who don't, and those who are now rick@linuxmafia.com looking for their dictionaries. -- Ron Fabre McQ! (4x80)
Being also on that mailing list, I couldn't help doing meta-commentary:
-- Cheers, There are 10 types of people in this world, those who know quaternary, Rick Moen those who only recently figured out Ron Fabre's "ternary" .sig, those who're completely confused, and those who hate self-referential jokes.
I also like:
