Postings to this are being entered as we do things or have time to write about things we've learned. You'll see the latest entry at the top of the page. If you're new to this blog you might want to go back and read from the start. There is also a subject index to help you find postings on specific subject areas. Last things, click on a picture to enlarge it, click the Play > on videos to watch them (they may take a few minutes to load on a slow connection).
