One of my claims to fame is that I have code running on computers in, on, under and orbiting the earth as well as leaving the solar system and scattered in millions of bits on Mars. You've heard all the rumours about the temperature in outer space going from minus 200 degrees in the shade to 200 degrees in the sun, well the gold stuff wrapping equipment that leaves the earth is used to reflect a load of the heat radiation so as to help keep the circuitry cooler (Allegedly).
