Software Developer (Senior) Paddedwall Software
United States United States
I've been paid as a programmer since 1982 with experience in Pascal, and C++ (both self-taught), and began writing Windows programs in 1991 using Visual C++ and MFC. In the 2nd half of 2007, I started writing C# Windows Forms and ASP.Net applications, and have since done WPF, Silverlight, WCF, web services, and Windows services.

My weakest point is that my moments of clarity are too brief to hold a meaningful conversation that requires more than 30 seconds to complete. Thankfully, grunts of agreement are all that is required to conduct most discussions without committing to any particular belief system.

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.

Software Developer (Senior) RADDev Publishing
United States United States
Roger has worked in IT for over 25 years in numerous roles (Technical Support, Quality Assurance, Capacity & Performance Engineering and Software Development).
During that time, he has recognized that software often just becomes another layer of work that the user has to wade through.
Sometimes technical documentation is like that too: so confusing and complex that it wastes developers' time.
That's why when he writes his books like Programming Windows 10 Via UWP and his articles (Practical Electronics For Makers) he strives to explain things in the shortest available space with the simplest language possible. Often that means, writing in a tutorial style with numerous images to help guide the user.
He believes the best guiding principle is Einstein's famous quote: "Everything should be made as simple as possible, but not simpler."
Richard Deeming
Software Developer CodeProject
United Kingdom United Kingdom
I started writing code when I was 8, with my trusty ZX Spectrum and a subscription to "Input" magazine. Spent many a happy hour in the school's computer labs with the BBC Micros and our two DOS PCs.

After a brief detour into the world of Maths, I found my way back into programming during my degree via free copies of Delphi and Visual C++ given away with computing magazines.

I went straight from my degree into my first programming job, at Trinet Ltd. Eleven years later, the company merged to become ArcomIT. Three years after that, our project manager left to set up Nevalee Business Solutions, and took me with him. Since then, we've taken on four more members of staff, and more work than you can shake a stick at. Smile | :)

Between writing custom code to integrate with Visma Business, developing web portals to streamline operations for a large multi-national customer, and maintaining RedAtlas, our general aviation airport management system, there's certainly never a dull day in the office!

Outside of work, I enjoy real ale and decent books, and when I get the chance I "tinkle the ivories" on my Technics organ.
