# RAILS 2.3.15

# Since <tag type="yaml"> was removed from rails' xml parsing,

OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

require 'open-uri'

module SocialUtils

  def self.get_facebook_shares(url)
  	f = open("http://graph.facebook.com/?id=#{url}")
		response = f.read()
		shares = JSON.parse(response)['shares']
		return shares.nil? ? 0 : JSON.parse(response)['shares']
	end

Ember.Console

This is a set of helpers for finding the application's currently active models/routes/controllers/etc. This isn't a straightforward process because of how Ember (rightly) encapsulates application objects, but it's useful in debugging environments to be able to quickly access them. And with the beta release of Ember Data, the store is not easily accessible without helpers either.

Usage

All helpers can be called directly if you provide them an application instance:

var BackboneAdapterMethods = {
	hide : function(){
		this.invoke('hide');
	},
	attr : function(map){
		this.invoke('writeAttribute',map);
	},
	text: function() {

When should you use DateTime and when should you use Time?

It's a common misconception that [William Shakespeare][1] and [Miguel de Cervantes][2] died on the same day in history - so much so that UNESCO named April 23 as [World Book Day because of this fact][3]. However because England hadn't yet adopted [Gregorian Calendar Reform][4] (and wouldn't until [1752][5]) their deaths are actually 10 days apart. Since Ruby's Time class implements a [proleptic Gregorian calendar][6] and has no concept of calendar reform then there's no way to express this. This is where DateTime steps in:

>> shakespeare = DateTime.iso8601('1616-04-23', Date::ENGLAND)
=> Tue, 23 Apr 1616 00:00:00 +0000
>> cervantes = DateTime.iso8601('1616-04-23', Date::ITALY)
=> Sat, 23 Apr 1616 00:00:00 +0000
