There are only 10 types of people in this world: those who know binary and those who don't.

Okay, for those who are the other type of people:

In binary: "10 types" means: 1 * ( 2 ^ 1) + 0 * ( 2 ^ 0 ) = 2 + 0 = "2 types" (in decimal)

Here you can convert from Binary to Decimal or the other way: Binary - Decimal Calculator
(it's a bit quicker than my calculation above.....

I had to learn Binary for my Computer Electronics class I took a few years back, but don't remember much about other than it's 0's & 1's

Been programming for 11 years and I can't say I recall any binary stuff from my university days. That whole area got a little "heady" for me. I'm a "git r done" kind of programmer. Wouldn't make much of a teacher but I sure enjoy what I do.
