That's great! Considering the millions of instructions that nowadays are executed just to cope with all layers of abstraction to read a sigle byte from a drive, we really need to start thinking about energy consumption and energy-efficient programming! When it's too cool, I spin up a kernel build, after a while the room is warmed by the heat of the CPU.
