14 of the world's best living programmers

It seems like there are lots of programmers out there these days, and lots of really good programmers. But which ones are the very best? Even though, there’s no way to really say who the best living programmer is, that hasn’t stopped developers from frequently kicking the topic around. ITworld has solicited input and scoured coder discussion forums to see if there was any consensus and, as it turned out, a handful of names did frequently get mentioned in these discussions. Based on that input, here are 14 people commonly cited as the world’s best living programmer.
