Great look at some ways of storing non-scalar data. I enjoyed the talk and thought there was some great details, including how to query JSON columns in MySQL and Postgres. I would've structured the talk a little bit differently, and would have possibly gone through each database technology separately, rather than looking at all of the technologies for each topic at once.

Really informative with pleantly of tools to research, the pace covered well.

The presentation was on the short side (20-25 min). Tips for improvement, show some tooling and/or examples of the design principles how we (as developers) can improve our applications. After all, there was enough time. In addition, I was very curious about numbers, how often do these specific attacks occur?

Funny and informative

Good comparison of all the different databases. Would have liked a bit more (opinionated) examples of when to use which database to show some of the strengths

Great introduction to Hadoop. Good delivery, with clear explanation of the concepts.

I came into this talk a complete beginner to Hadoop. So I'm not sure the talk was aimed at me.

Michael is clearly very knowledgeable and covered a lot of ground in the talk. I would have loved to have seen a common data example that could be followed through, culminating in how to interact with it using Phresto. As a summary of services the talk was great.

Brilliant and enjoyable talk. Informative, and the advice given was easy to understand and clear examples were given.
Loved the analogy to the real world high-risk systems like nuclear power plants and aeroplanes, was awesome to hear more about how those systems are designed and operated and interesting to hear the failure stories too! The occasional jokes were great too (I won't be mindlessly clicking on alerts from now on haha).

The talk was well structured and Chris was well prepared. Kudos for staying completely calm despite losing the slides for a while!

It was a nice run through all the different technologies to store non-scalar data and a nice refresher about all the different solutions out there. Nothing "revolutionary" for me personally.

Kudos to Derick for staying cool and composed despite the mic problems!

Such a great talk. Really really informative run through what's coming out in 7.2 and beyond, and I LOVED the easy to follow examples of opcode caching optimisations. Enjoyed the history intro too. Thanks for all the graphs and stats on CO2 savings - that gives us all a great argument to go back with to our business owners and badger them about upgrading to 7! :)

Very well prepared and structured talk, and delivered without a glitch!
