I have posted the slides for the first lecture on Canvas.
In general, lecture materials will go into the “Files/lectures” folder on Canvas.
The video capture from the first lecture is posted at on Kaltura Mediaspace. The player supports sped up playback (1 1/2x and 2x). (update 1/24: this link should work now)
Watching the video or looking at the slides are not a substitute for attending the lectures, but may be better than nothing.
