I’ve tried to mention sources as much as possible. In case I forgot to give someone his or her due credit, I’ll do so as soon as possible.

Feedback on stuff that doesn’t work yet, on the site itself and in the presentations and the example files, is much appreciated.

The content on this site may not be used for commercial purposes. The presentations and example files (in whole or in part) may not be used in work, courses, classes, books or presentations without my express permission. I hope these files will add to your knowledge of the programs covered.

The use of the files is at your own risk.
