Code examples from a couple projects.

Gistr.js

/** 	This is an extension for Adobe's open source editor Brackets.io that creates Gists easily
	I think its pretty clever code on a couple levels, but mainly because operating systems prevent
	browser technologies from accessing the clipboard directly. So instead, I exposed the URL as a string within
	a text field, and select it, so the user only needs to hit their Copy shortcut.
	
	I think its cool.
