In addition to some lightning talks, Chris Ball will discuss some "free" Ember magic - Loading and Error Substates:
Ember is built around conventions. Conventions are great for developers because they can leverage framework decisions to help eliminate a lot of boilerplate or repetitive code. Loading and Error Substates can and should be used in your Ember applications to provide user feedback for these common states. We’ll look at examples of nested templates and built-in event hooks. Leveraging tools in Chrome, we’ll simulate using an app on a slow connection to see how important and easy this type feedback is.
