Links to lecture and lab videos

The 2009 lectures and labs videos are packaged using Adobe Connect. Those files are available here.

Links to each lecture or lab are in the following calendar. They are labelled by their contents. On campus students are welcome to use these if you miss a class or want to see something again.

We anticipate posting videos within a few hours of the end of lecture.
