if after the first step (u += 0xe91aaa35) you apply this function: invert = lambda x: ~int(hex(0xffffffff - x)[0:-1],16)
it returns the correct value (corrected the overflow) but there is still something wrong, still looking into it, if someone knows how to do this, feel free to comment :) -- http://mail.python.org/mailman/listinfo/python-list
