I have removed the following AJAX demo applications from the menus because changes in APIs have made them nonfunctional: Stickam, Technorati, Amazon, Yahoo! Video Search, YouTube Favorites. Some of these relied on web services that are no longer provided.
My client dry spell appears to be over because I am now doing some work with Drupal and Elgg which will bring in some money. I may need to discontinue my language study if I become too busy doing other projects.
Yesterday I learned how to create Elgg plugin settings and today I figured out how to create tabs. I still have not figured out how Elgg 1.7 is going to use unit tests in plugins. There is no sample code for that and my attempt to add an unit test to a plugin does not work.
