need to support

• bi-directional model to select2 selected object changes
• select2 data-set changes
• select2 object to ng-model mapping that supports attributes, not necessarily the whole object, similar to <option ng-repeat value={{obj.attribute}}>{{obj.humanReadableAttribute}}</option>
• should work for both multi and single-value selects
• should support optgroups

Problem:

• There's a module that knows how to load (and re-load) data through an API, and stores it locally.
• Multiple modules access the loaded data, and transform them into a different representation (each module does a different transform), also storing them locally
• The transformed data is exposed to the view, with a 'loading' indication when the original data is (re)loaded and/or the transformation is in progress.

##API idea

Promises support:

• on resolution callbacks, where the transform function can be attached.
• a isResolved attribute, which is false when the promise has been started but not yet resolved.

Task callbacks, dependencies, cached results

Discussion on a celery API and implementation that solves

1. Ability to dynamically add callbacks to already running tasks
2. Tasks with dependencies
3. Caching/invalidating task results
4. Being able to stop/restart a task

Async result that allows adding callbacks

Jenkins stuff

Ideas on what to do per build, when to trigger builds, etc.

Basic build per project

• compile
  • triggers build failure
• run unittests
• triggers build unstable
