You probably will only be interested in my software section or maybe my blog.
I've also been spending a lot of time writing solitaire games. Here's some links to games you can play right in your browser (or on your phone): Freecell Solitaire, Klondike Solitaire, Flower Garden Solitaire, Spider Solitaire, Sea Haven Towers Solitaire.
