I used to have lots of articles on my web site, but I dramatically changed the site's format to this new style in early 2021, and I find that I just don't have the time and motivation to bring all of the old content back. This site doesn't get enough traffic to warrant all of that effort. So, you will find those articles that are still applicable to what I am doing or in which I am still interested, listed below. Of course, new content will be added over time.
