Escaping tabs with progressive (web) apps... A short keynote talk I gave yesterday at Velocity NYC on how Service Worker unlocks a whole new life-cycle for web apps: offline, add to homescreen, push notifications, and much more. Best of all, these progressive (web) apps retain all the best properties about the web: easy to discover, instant gratification for the user, secure, ..., and built with web technology!

First implementation of requestIdleCallback is in Chrome Canary!

What is it? It allows applications to cooperatively schedule background tasks such that they do not introduce delays to other high priority tasks that share the same event loop, such as input processing, animations and frame compositing. 

For more details on the API, the spec, and more examples, see:
https://w3c.github.io/requestidlecallback/

Finally, to get started:
- Boot up Chrome Canary
- Enable chrome://flags/#enable-experimental-web-platform-features
- Restart the browser
- Experiment with rIC, ..., and please provide feedback!
