Using new Intel Core i7 instructions to speed up string manipulation. Fascinating stuff. SSE ftw

Good presentation on C compiler optimization, via Cal Henderson. 'People often write less readable code because they think it will produce faster code. Unfortunately, in most cases, the code will not be faster.' I particularly like 'Fancy-Schmancy Algorithms': 'If you have 10-100 elements, use a list, not a red-black tree; Fancy data structures help on paper, but rarely in reality. (More space overhead in the data structure, less L2 cache left for actual data.)'
