Mauricio’s found some CFLAGS in YARV which will power-up the opcodes to give Ruby a highly swift route through recursion. He runs an Ackermann on Ruby HEAD for a time of 1.815 seconds, compared with St. Valentine’s YARV which clocks in at 0.027. (Note that he’s including a 0.02 sleep!)
I’m dying for Nintendo Power to put out a big fold-out map of YARV opcodes and cheats. Anyway, be sure to check the leftmost column of ko1’s map before telling Slashdot that Ruby is leaving streak marks everywhere, lest we become the new heirs to Alex Chiu. You can’t see it, but I am winking.
