The correct order is: debug, then ship.
If it isn't broken, don't fix it.
If you fiddle with something long enough, it will break.
It works better if you plug it in.
If it's wedged, power-cycle it.
A working example is worth a thousand manual pages.
Failures occur where two parts join.
Demos cause failures.
Systems grow more complex with time.
If it's too complex, rebuild it.
Small parts vanish when dropped.
Don't build from components what you can buy pre-packaged for less.
