Flask + uWSGI + nginx Primer

I've been having trouble with serving a Flask app via uWSGI and nginx, so I thought I'd put together some of the basics to help out others.

How this shit works

Flask is managed by uWSGI.
uWSGI talks to nginx.

Do not try to return properties from controllers, return the whole object.
- Eg: If you want to read a property of the first object of hasMany: do not return elements.firstObject.property. The hasMany are lazily loaded, thus not visible for models/controllers! The correct way is this: return the firstObject as computed property(elements.@each) and in the view bind the property. This way when the collection is lazy loaded, the view is notified and will update.
Caution with collections in computed properties. You can observe the collection pointer or the collection elements(using @each)! They are different. Observing the collection pointer will notify when the collection is replaced or deleted, but not when an item is added! For this, you need to use @each.
Displaying multiple model type on the same page is done with render(you can do it also with outlets but less clean).
Observing a collection in order to apply a JQuery plugin is done using a CollectionView with a function observing content. In t

Ember Router Async Facelift

The Ember router is getting number of enhancements that will greatly enhance its power, reliability, predictability, and ability to handle asynchronous loading logic (so many abilities), particularly when used in conjunction with promises, though the API is friendly enough that a deep understanding of promises is not required for the simpler use cases.

	* `Ember.MergedArray` is an array that observes multiple other arrays (called source arrays) for changes and includes
