Ember.js and Firebase today. Tried out the EmberFire lib provided by Firebase to use Firebase with Ember-Data. I also used the Ember CLI for the first time, can really recommend it. Wanted to see how easy it would be to build an real time syncing Ember.js app and then deploy it to the new and easy to use Firebase hosting service.
It resulted in a simple planning poker app to help with the sprint planning for my remote team. I've uploaded the source to Github.
