Knuth Got It Wrong 298
davecb writes "Think you've mastered the art of server performance? Think again. Poul-Henning Kamp, in an article at ACM Queue, finds an off-by-ten error in btrees, because they fail to take virtual memory into account.

He's one of the top three UNIX gurus in the entire world. In fact, the Internet today is what it is thanks to his hard work and dedication.

I forget the exact amount, but it was like PI or E dollars for every typo. I am not sure what the payment is for an algorithmic error.

Thanks.
