Re: RE: Dear Coders - Rules You Learned in Kindergarten

It's getting on for 20 years since I studied it at uni, but there are methodologies to development and testing that you simply have to follow when working on critical or embedded systems. This allows for you to consider race conditions and unexpected input values as well as simple coding mistakes. Once you go live, patching is incredibly difficult, so yeah i imagine it is possible for someone to have gone years without a bug being found in their code once it had gone live.

I'm sure quite a number of bugs get found during unit testing, then more once your code gets to interact with others in system testing. As was highlighted, a bug in the production environment could be catastrophic - be it nuclear meltdown or planes dropping out of the sky!
