If you find the links to any of my tutorials broken, you might try either:

1. Going to Google or Bing and searching the web for pages having the same title, or

2. Going to More articles by Richard G. Baldwin at Developer.com and searching that page for the tutorial by title.

One of those two options is almost certain to lead you to a copy of the tutorial.
