This site has topics that I have worked on, professionally or for fun. There’s also just things that I happen to think about long enough to write something about.
I have ads and links for more information and purchase. I try to keep links up to date but sites disappear, items are removed and links break. I apologize if you get an error message. You can use my Search page to google directly from this site (see yellow chair at left).
If you click on my Adsense ads or buy through my Amazon and eBay links, I get a small percentage of revenue generated. You’ll see various “Amazon Picks” at the right and bottom of posts. I choose those – based on relevance to the topic, whether they seem interesting, price, availability and customer reviews. You can go to Amazon and buy anything you’re looking for using my search box in the right margin. Thanks!
