Over at Informit they've got a great Q&A with Donald Knuth. Twenty luminaries in computer science ask Knuth questions about himself, his work, and computer science. The questions are much more interesting than the usual session of this sort so it's definitely worth taking a look.
Among the questioners are Jon Bentley, Radia Perlman, Robert Sedgewick, Silvio Levy, Al Aho, Guy Steele, Robert Tarjan, and Andrew Binstock, just to mention a few who are familiar to me. It's no wonder the questions are of such high caliber.
If you read the entire article, you'll learn lots of interesting things. For me, the most astounding thing was to learn (or more precisely, be reminded) that Knuth has been working on The Art of Computer Programming for more than 50 years. I'm pretty sure that that's longer than most Irreal readers have been alive. As I say, astounding.
