I would like to thank everyone who attended, supported, and helped organize this meetup with of-course a special mention for our presenters Julian, Mihai, and Alessandro!
I had a great time yesterday evening and learned many new things along the way. From some personal feedback I got, I know that there were many people who really appreciated the presentations and the open discussion. If there is more feedback about improvements, changes, or things that you would like to see in a next meetup don't hesitate to share here or privately. I will post the videos online on youtube once I finish some small post-processing. Then I will update the talks section in the website [1] with links to the slides, videos, and other relevant information.
