I retired from the U.S. Department of Energy in 2009 and decided to do all the things I had wanted to do but never had the time. One of these was learning more about how to program for the Web. I learned enough PHP to create a web crawler for a non-profit genealogical organization and enough HTML and CSS to create several web sites. I am currently taking on-line courses from Udemy on the correct way to use HTML5, CSS3, and JavaScript to create responsive web sites. All along the way, I have sought and received valuable advice from far more experienced hands on Stack Overflow!
