When stuff has to work in the dark, while it's raining and the operator is using a flashlight to read a plastic cheat sheet, 10,000 mile from home, it really has to work. Not only do you write 10 lines of test code per line of production code, everything must be configurable. You cannot hard code any constants in your code. It all has to be in flash, accessible and changeable by the most rudimentary means from a remote system control that might have the equivalent of a 300 baud connection. This is a really great post! I hope a lot of people listen. This isn’t too far from my own experience.
