Sam and Ryan talk about

• Functional CSS training at EmberConf
• Some ideas for hiding styling implementation details from templates
• A new setup for multiple staging environments
• An idea from data modeling called “Making the impossible, impossible”
• How to use data down actions up effectively in forms

They also answer some listener questions:

• When should I use polymorphic or reflexive relationships?
• When do I need to explicitly name a relationship’s inverse?
• When should I reference relationships and when should I embed them?
