[bulibuta]

I am a university professor teaching Operating Systems based on the Dinosaur book. I always use the authos' slides to which I add my own notes and extra/missing concepts.

My colleagues from other universities here do exactly what you say, they do their own summary which is an effort I also don't understand.

The only moment when I felt I needed to do my own slides was with the pandemic online courses that refrained me from using the whiteboards in the amphitheater. But in the end the graphical tablet saved me from that.
