The videos from Google I/O 2016 are online and there is some great content there. My favorite so far is this one from Ilya Grigorik on resilient web applications. It does a fantastic job explaining unexpected performance and network failures–way better than I did in my JavaScript Forensics talk.

I really enjoyed the statistics on failed network requests in mobile Chrome; way more common than most people imagine. We really need to plan ahead on what kind of experience we create for our users when networks and devices fail.
