Black absorbs infared heat better, not radiate it. The radiating material, not it's color, is what makes the difference when you want to cool something. Ever paint your CPU cooler contact plate black before putting ArticSilver on it?

No, the colour of an object affects its radiative properties exactly the same way as its absorptivity. The reason you don't paint a CPU cooler black is because it doesn't cool by radiation, but by conduction/convection.

Ok...so AES was thought to require 2^128 time units to brute force. So 2^119 time complexity means essentially that the new algorithm takes 2^119 units of time to complete which is a lot better, and they think it might be able to optimize it down to 2^110 units of time.

Where does 2^128 come from? I would have expected 2^255, since on average you need to try half of the 2^256 possible keys.

If it's not in the computer, it doesn't exist.

Working...
