Dear KV,

Though you wrote "Since I've talked about measurement before, let's talk now about the importance of algorithms" I'll take advantage of the opportunity to quote Prof. Knuth: "premature optimization is the root of all evil (or at least most of it) in programming." Measure first, figure out where your programs are spending the bulk of their time, then look to improve the algorithms. Also, I will say that there are easier starting (or continuing) places to learn about algorithms than Knuth, including Robert Sedgewick's "Algorithms", or "Introduction to Algorithms" by Cormen, Leiserson, Rivest, & Stein. Last, for those wacky NUMA architectures, see Maurice Herlihy and Shavit's "The Art of Multiprocessor Programming."
