You could really tell this speaker was very knowledgeable and his presentation materials were excellent. Would've very much liked to see the second part though.

Great speaker and polished materials. Would've appreciated technical details on specific attacks, maybe for next time? Thank you!

Loved helping out on joind.in. Thank you to Andreas and Jos for their patience and the organizer for getting us drinks and snacks.

Speaker seemed very comfortable, materials were very polished and interesting.

Brilliant as ever. Felt a bit rushed at the end but even that was expertly done.

Excellent talk. It was not rushed and all, and still conveyed a good message. Thank you!

Really excellent. Bits of humour, great content and information on BC for code.

Great talk! Loved the quizing! Makes you realize that even adding new unrelated stuff can break backwards compatibility

For a beginner it was hard to understand in the beginning what were the differences between caching and using read models. Of course, this is the fact that it happens on change vs on request, and the last one of those causes big delays for a lot of users at the moment of a cache invalidation. This is something that would've been better to explain in the first 10 minutes of the talk and would've made the rest of the talk stronger.

Satisfied the curiosity, gave solid advice for what to do with and was very calm and composed. Excellent talk!
