There's a surprising number of programmers who can't count in binary, or who can't do bitwise operations , or ... any number of things. It's surprising how far some people can get with their hands tied behind their backs. I wouldn't recommend it of course. Also it might possibly be a kind of warning flag: how can someone constantly be exposed to this stuff and never pick it up? But somehow it does sometimes happen!

[ For folks wondering why I'm talking about counting: Bits and bytes is all about learning to count with just 1 finger: 1, 10, 11, 100, 101, 110, 111, 1000, ... And the largest number you can count up to in a byte is 1111 1111 of course (A byte has 8 Binary digITs, and the highest number you can count to in a byte is having all those digits be 1s. In decimal this is the number 255. If you use a computer a lot, you might have run into 255 more often ). ]
