Water distortion filter, implemented with Starling's "DisplacementMapFilter".
private function addDistortionTo(target:DisplayObject):void
{
var offset:Number = 0;
var scale:Number = Starling.contentScaleFactor;
var width:int = target.width;
var height:int = target.height;
var perlinData:BitmapData = new BitmapData(width * scale, height * scale, false);
perlinData.perlinNoise(200*scale, 20*scale, 2, 5, true, true, 0, true);

Reset for form elements written in SCSS
/* ----------------------------------------------------------------------------------------------------
SCSS Form Reset Helpers - Forked from: https://gist.github.com/anthonyshort/552543
Intended usage:
- MIXINS: for very specific use cases, when you dont want to reset absolutly all the forms, very verbose output.
- PLACEHOLDER SELECTORS: use as extending classes. Less verbose, more generic overrides.
A couple of things to watch out for:

IndexedDB Full Text Search (Proof of Concept)

This demonstrates the implementation of full text search for documents in Indexed DB.

  • Word-breaking and stemming is used to create a list of terms for each document.
  • Document records are annotated with the list of terms when added to the database.
  • A multi-entry index on the list of terms is populated.
  • A query is similarly processed into a list of terms.
  • A join over the terms is implemented using multiple cursors on the index.

The necessity of annotating records with the word list to populate the index is a limitation of the current Indexed DB API. A feature request to support custom
