Thanks Mihai for proposing to give a talk! Looking forward to it. I just created and announced the event on meetup [1]. The agenda may change but hopefully the date/time will remain the same.
Apriori we will use a regular Zoom meeting to host the event (like last time) but if people have other preferences let me know. I will share the respective link here and in the meetup platform as we approach the date.
