Interesting topic with an interesting concept of delivery. Alan had a few volunteers from the audience help him explain how Oauth2 works, by exchanging paper cards with various credential data and tokens between themselves.
Although a very interesting concept that has some potential, there were too many factors that derailed the flow at times - participants seemed confused at times and all started talking, commenting and asking questions at the same time, while Alen tried to explain everything. I'm sure with some practice on his part, Alen can eliminate the chaotic parts and turn this into a very interesting live demo.
Interesting talk, congratulations for open sourcing your work. I think the talk would be more interesting for the developer population if you would shorten the presentation part and focus on the technical problems and creative solutions you came up to tackle those problems.
Domagoj gave a very interesting presentation which sparked a lot of discussion and comments afterwards. There was a lot of material to cover, so 30 minutes didn't seem like enough time.
I was hoping for a more technical talk - I'd suggest reorganizing the content and focusing more on the use cases with live demo examples, perhaps showing the code base and explaining the building blocks and principles behind the project.
