It's interesting that when I interviewed him, he has all these built-it book cases behind him in his office. The idea of not needing the internet but just occasionally grabbing a book from behind you to look something up when developing software is very appealing to me.

When I interviewed Brian Kernighan one of his complaints was how so much of modern programming is just looking things up rather than building things and I think that Richard has escaped that fate by building things himself.
