The following session types are suggested (if you have a good reason to deviate from the format please add this to your description): Session 20m: A short session of 20 minutes, ideal for a use-case or technical insight. Session 40m: A long session of 40 minutes, ideal for a technical deep dive. Workshops of half an hour, 1 or 2 hours on a specific topic. Lightning talks of maximum 7 minutes..
