One of the best presentations I've seen. Loved the simplification to explain things while still retaining the tech nitty-gritty :)

Excellent Presentation. I really appreciated his presentation style and with humor mix into this made it more engaging. This was full of nuggets and gave a very clear visual of the process in the forefront as well as the underlying infra. Great job!

Awesome talk. These are insanely hard challenges to overcome and it's really cool to learn from Facebook's example.

This is very informative. Awesome Talk!

Great talk, covers enough technical detail but in an accessible way for someone who has no experience with video streaming.

Why are InfoQ videos only 720p max resolution. The presentations are mostly pixelated.

"How do you deal with porn?"
"We have both people and automated processes monitoring for porn, but yes, it's a _hard_ problem"

What a memer. Great talk.

Wonder why nobody asked in my opinion obvious question: What if millions of users connect to a single POP to watch a popular streamer? How BigCache nodes handle it? Obviously people wathing the same stream in one POP are hitting the same BigCache node, does it have replicas? If yes, how many times each cached segment will be replicated? In my head this should be dynamic, I mean for some streams you need 2-3 replicas for balancing, but for some popular ones (for this particular PoP) you may need 10-15. If so how do you do this dynamic replica creation I'm curious. Thanks in advance.

Can someone share what tool was used to make the presentation?

[Ashley_montz]

such a good speaker. I really enjoyed the talk

Ironically, looking back now after 5 years, how well you've done then eventually Tiktok beats you so hard that end with how many users do you still have now?

the protocol comparison in the talk is useless. looks like a go-to winner. No trade off
