A thing I have to tell developers who are new to banking, over and over:
Never give a trader a price without a currency, a timestamp, and a source.
The aphorism I would add to Simon's List (capitalised) is:
"Make sure your baby learns to play well with other children".
I'm an end user developer, and everything I do has to work on a busy desktop, not seize resources needed by the other processes, exchange data with other end user applications, and provide interfaces that work for users, managers, system administrators and support staff, and documented APIs allowing other developers to extend and adapt my work.
A large part of all the hours I have ever worked, is working around or against applications that do these things badly or not at all: no software, anywhere, gets to work in splendid isolation in a universe of its own, but half the sofware ever written is implemented as if it did.
