Updates

04/10/2011 - Updated application.js and application.rb thanks to @rebo's comments

In this article, I will walk through some simple steps to get a [demo app][2] up and running with [Backbone.js][3] and [Sinatra][4] on [Heroku][5].

Why objects (usually) use less memory than arrays in PHP

This is just a small post in response to [this tweet][tweet] by Julien Pauli (who by the way is the release manager for PHP 5.5). In the tweet he claims that objects use more memory than arrays in PHP. Even though it can be like that, it's not true in most cases. (Note: This only applies to PHP 5.4 or newer.)

The reason why it's easy to assume that objects are larger than arrays is because objects can be seen as an array of properties and a bit of additional information (like the class it belongs to). And as array + additional info > array it obviously follows that objects are larger. The thing is that in most cases PHP can optimize the array part of it away. So how does that work?

The key here is that objects usually have a predefined set of keys, whereas arrays don't:

I wrote this in early January 2012, but never finished it. The research and thinking in this area led to a lot of the design of Yeoman and talks like "Javascript Development Workflow of 2013", "Web Application Development Workflow" and "App development stack for JS developers" (surpisingly little overlap in those talks, btw).

Now it's June 2013 and the state of web app tooling has matured quite a bit. But here's a snapshot of the story from 18 months ago, even if a little ugly and incomplete. :p

In the beginning…

Intro to tooling

	namespace Ormigo\Tests;

	use Symfony\Component\Templating\EngineInterface;
	use Symfony\Component\HttpFoundation\Response;

	# vi: set ft=ruby :

	this_dir = File.dirname(__FILE__) + "/"
	require this_dir + "vagrant/hostmaster.rb"

	Vagrant::Config.run do \|config\|

	# define some colors for our output
	def colorize(text, color_code) "#{color_code}#{text}\033[0m" end

 defmodule Languafy.Web.Context do
   @behaviour Plug
   import Plug.Conn
   alias Languafy.User
   def init(opts), do: opts
   def call(conn, _) do
     case build_context(conn) do
       {:ok, context} ->

	function it($m,$p){echo ($p?'✔︎':'✘')." It $m\n"; if(!$p){$GLOBALS['f']=1;}}function done(){if(@$GLOBALS['f'])die(1);}
