gggustafson
Software Developer (Senior)
United States United States
In 1964, I was in the US Coast Guard when I wrote my first program. It was written in RPG (note no suffixing numbers). Programs and data were entered using punched cards. Turnaround was about 3 hours. So much for the "good old days!"

In 1970, when assigned to Washington DC, I started my MS in Mechanical Engineering. I specialized in Transportation. Untold hours in statistical theory and practice were required, forcing me to use the university computer and learn the FORTRAN language, still using punched cards!

In 1973, I was employed by the Norfolk VA Police Department as a crime analyst for the High Intensity Target program. There, I was still using punched cards!

In 1973, I joined Computer Sciences Corporation (CSC). There, for the first time, I was introduced to a terminal with the ability to edit, compile, link, and test my programs on-line. CSC also gave me the opportunity to discuss technical issues with some of the brightest minds I've encountered during my career.

In 1975, I moved to San Diego to head up an IR&D project, BIODAB. I returned to school (UCSD) and took up Software Engineering at the graduate level. After BIODAB, I headed up a team that fixed a stalled project. I then headed up one of the two most satisfying projects of my career, the Automated Flight Operations Center at Ft. Irwin, CA.

I left Anteon Corporation (the successor to CSC on a major contract) and moved to Pensacola, FL. For a small company I built their firewall, given free to the company's customers. An opportunity to build an air traffic controller trainer arose. This was the other most satisfying project of my career.

Today, I consider myself capable.
