I am still working on the course website. The PHP/mySQL interaction is turning out to be a bit more complicated than I remembered.
In the course of getting that running, I just realized that some of the links on the Notes page refer to PDFs that aren’t currently available. In some cases, the notes may no longer be relevant. In other cases, I need to regenerate the PDF. If you click on a link you’re interested in and get a “Not Found” error, let me know.
