Wow, a content-less presentation. The topics list was good, the list of three sample questions was ok. But then didn't actually have any content about system design after that. Reminds me of when I was a consultant and didn't have time to prep for a presentation.
Thanks Akela Drissner for the workshop. Very informative. As Alexey said, people shouldn't be overwhelmed by the details. Just take some time and go over the notebook again. Good thing is, it has all the details you will need for adaptation to another use case.
