I started my programming career in telecom where your code had to work 24x7x365, no excuses. And so my code is what I refer to as "kindergarten code". It's always as simple as possible, even if it takes a few more lines to accomplish. It should always be easy to understand with no fancy tricks, no showing off allowed, no cramming 20 lines worth of code in to one convoluted undecipherable mess of a line.
Someday, someone else is going to have to look at your code, so don't be an asshole, make sure they have a fighting chance of understanding what you've written and why.
