Lecture 2 (including recording) and Problem set 2 now available

Lecture 2 (including recording) + Problem set 2 is now available here. Unfortunately, the recording is again only capturing my presenter view, and not what was shown on the projector screen. For some reason, the recording software would not allow me to record the external screen. While I will try to investigate how to avoid this issue, we might have to live with it for the rest of the semester.
