72 times faster than original quasicrystal code. And i think thats not the ultimate limit,could be possible to get within half a second

For a second I thought someone had finally broken out the Asm and pwned everyone else.

I have a habit for checking asm output of compiler to check if they make some part of code(like inner loops) calling slow opcode like

C++ is a good language. It is not a perfect language because it inherits from C. C is a flawed language where many things are left undefined. C is an ancient artifact that serves no purpose outside of the domain of kernel design. Because of the improvements made upon C to form C++, beginning programmers and veteran programmers alike may be led astray, thinking that modern C usage is a good idea. It is a mistake to believe the success of C++ justifies the continued use and popularity of C. Just because C++ is successful does not mean the language it has inherited from is of high quality.

How are little girls disgusting? If that's not it, how is a grown man masturbating to little girls any more disgusting than another grown man masturbating to women?
