The guys working with memory management tool Valgrind (see previous story at /.) are now up to version 1.9.5, and it's stable! Even more, there is now also an excellent GUI tool for using Valgrind for serious cache optimization; check out KCachegrind!!! Besides, who would have thought cache optimization would be not only intellectually but also visually beautiful?"
