David Lloyd Arthur Rall b. 1959 d. not yet
First program written in FORTRAN in 1973. I wish I had saved a listing of the source. It was a cute little crew race that used "<<<<<<<<", "||||||||", and ">>>>>>>>" in succession to emulate an "eight" rowing its way across the screen. In a pathetic way this was a graphical representation of a river with some boats.
Latest programming work includes a satellite orbit propagator (Simplified General Perturbation model SGP4) and a 3D Earth visualizer (C++, OpenGL, WGS-84). Somewhat similar to the AGI Satellite Tool Kit. I freely admit to some pseudo plagiarism of the style of their GUI.
I currently work and live in the Washington, D.C. area for a smallish company that does contracting for various government agencies.
