I liked the talk and did get some good value out of it, but I didn't feel that the topic focused enough on what went wrong. There was a good amount of the talk speaking about how the system was architected without any reference to what was wrong about it.
The speaker had great charisma and spoke very well.
This was a great talk with lots of extremely valuable insight. It was kind of unusual for a keynote talk, but since it is such a universally valuable concept, I liked the fact that all of the attendees got to experience it. The presentation was well done, and the speaker had a good presence.
I definitely don't agree with "Don't laugh at PHP jokes" though. Self deprecating humor is hilarious :p
I have pretty much the same feedback as a lot of the comments already posted here. The topic is extremely valuable and needs to be addressed, but I didn't feel like the talk did it service. When overcoming these challenges, I feel that positivity and getting people excited about solving these challenges is the way to go. This talk didn't fill me with positivity or optimism at all. It was very much a downer.
The talk was very interesting. I really liked the comparison of the various storage methods and the discussions of the pros and cons of each. It was way more helpful than the fanatical presentations about one particular product that claims it's a silver bullet.
I learned a broad range about different data types in the different "databases", and how to query them.
I enjoyed the talk but it felt as if the topic was more focused on specific tool(s) that were used in conjunction with AWS. I was hoping that the topic would be more about AWS in general.
The information that was presented was well written and easy to understand, and the speaker was eloquent and charismatic.
An insightful talk that inspired me to learn more about how efficient response times were accomplished. I would have liked to see more of a deep dive into how exactly this was done. The talk did present information along those lines, but it felt like there was more to the story. Specifically, I'd like to hear more about how Swoole was used.
Kudo's to Demin for tackling a tough topic when English is clearly not his first language. He explained the topic clearly and was very easy to understand even given his strong accent.
A good general topic to start the conference off with. The speaker was charismatic and spoke clearly. The content was entertaining and educational.
I was expecting a bit more comparison and benchmark on how these things can work. Real-life examples would be great.
Also during the slides presenter went from guitars to some student records and then back to guitars which was strange.
Great
The first half of the talk felt like it was more for beginners, with a lot of good practices which most senior devs should already be aware of (it doesn't hurt to reinforce it though). I mostly enjoyed the second half of the talk where I learned about a few tools I wasn't aware of, and learned of some capabilities of tools I knew, but didn't realize they had.
