Notes about the videos
- ALL VIDEOS FOR SPRING 2010 COURSES WERE DELETED ON JANUARY 25, 2011. Links will not work!
- The videos are all uploaded to Screencast.com and are in my Classes_Spr2010 folder, which is public. If you don't see a link for the video you're looking for, it may already by available in that folder, even if I haven't posted the link yet.
- If you notice any problems or abnormalities, please let me know. For example, there have been times when I forgot to turn on the microphone and didn't notice.
- Some videos that you might expect to be available may be missing because of technical difficulties. Sorry.
- For students, please consult your notes or the teacher version of the PowerPoint if you can't read what's on the screen. See the PowerPoint page.
