This article has been given a more permanent home on my blog. Also, since it was first written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.

You're Missing the Point of Promises

Promises are a software abstraction that makes working with asynchronous operations much more pleasant. In the most basic definition, your code will move from continuation-passing style:

getTweetsFor("domenic", function (err, results) {
 // the rest of your code goes here.

/**
 * The invocator function creates a new instance of the provided constructor
 * which is also linked to a method that it contains.
 *
 * Check this fiddle for a live example: http://jsfiddle.net/thanpolas/Aky9Y/7/
 *
 * Invocator only works for pseudo-classical type of classes (prototypical).
 *
 * Requires 'bind' and 'isFunction', currently use underscore's equivalents.

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

Using Obj-C with MacRuby/Rubymotion

This little post aims to help you to translate Objective-C Blocks into Ruby blocks. Let's start by taking a look at few examples of iOS API call where blocks are used for animations and enumeration

Ruby Lambda Syntaxes:

Im Rubymotion and MacRuby you can use all the Ruby Lambda syntaxes that are:
