Re: That quip about hard things in CS...
There are only 10 kinds of people when it comes to understanding binary...
I have always thought it's more accurately actually 11 kinds of people.
1) Those who understand binary.
2) Those who don't.
3) Those who understand the theory and can explain the concept to others, but then proceed to put the numbers in the columns back to front because last time they had to do anything in binary was (equivalent to) two lifetimes of the new entrants to the workplace ago.
