Montreal is the second largest French city in the world, next to Paris. I like the fact that real estate is dirt cheap here, so cheap that software development alone enables a financial capacity to afford a nearly 2,000-square-foot luxurious condo right in the middle of Downtown Montreal, a 5-minute walk from my office, beside the largest and oldest art museum in Canada with visitors and tourists from all over the planet, including Hollywood stars. I've chosen C# as my first language at Code Project, because it is the only garbage-collected language and platform meeting the performance requirements for real-time game programming, proven by Unity. Code must be perfect, providing safety, security, performance, scalability, availability, reliability, maintainability, extensibility, portability, compatibility, interoperability, readability, productivity, just to name a few. C# is the only language that comes close, with Rust second to it. That being said, even C# is far from being perfect. I dream my own programming language, while on my journey to it. We will see how it goes!

gggustafson

Software Developer (Senior)

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.
