Tech Stacks

Technologies I have experience with

I have used many technologies over the years. In the days before windowed operating systems were the norm, I spent a lot of time in the command line on unix, linux and windows systems. I used a lot of different editors and IDE's, including command line editors, WYSIWYG editors, and full IDE's.
