We use FORTRAN to develop missile models because the language is fast, has low overhead and provides the percision that is needed for flight calculation. It is legacy code that incorporates differential equations to do calculations and so having low overhead is beneficial to speed. If it runs too slow or doesn't provide enough precision we can't use it. Even recurrsive functions cannot be used if it doesn't meet real time timing constraints. FORTRAN is fast and easier than assembler.
For new clients I always get half up front. It does two things, 1. insures the clients interest in the project 2. insures you get something for your work if the client bails. I usually require NDA from the client so they don't drop me for someone cheap once we're making progress.
I have a keytronic lifetime series keyboard cost about $50 and a kensington expert mouse track track ball ($99). As much time as I spend behind the screen on the keyboard it's well worth the investment. Why an expensive keyboard, because it's all about touch. This keyboard has a consistent touch for all the keys unlike some dell keyboards that have that lazy key and that stiff key here or there.
BTW why do they call ita keyboard, my son asked.. should it be called a button board?:-)
