Notes on YouTube lectures given by Lindsey Kuper, Assistant Professor of Computing as UCSC
Please excuse cases where I might have given a poor summary of something Lindsey was saying — I'm a student here...
There are no notes for lecture 1 as this was concerned with course administration and logistics.
