I gave a tutorial on the use of Essence and Conjure at the 2019 ACP Summer School in Vienna.
Let me embed the most important ones here :)
The organisers Andrea Rendl and Tommaso Urli did a great job. They even recorded some of the talks and an interview with all of the speakers. I believe they will publish these real soon now™.
This was a great experience and I really enjoyed it. I had attended the 2011 edition of the same summer school and it was a great experience as a student then. I got to meet a lot of my peers and learned a lot. Also: banana boat.
