# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.
#
# Once you're done here, go to
# http://www.gnu.org/software/make/manual/make.html
# to learn SOOOO much more.

1. Set up the bower gem.

2. Follow the Bower instructions and list your dependencies in your bower.json, e.g.

   // bower.json

{

gr2m

function Worker(app) {
    this.app = app;

    app.on('add:$email', this.sendEmail.bind(this) );
}

Worker.prototype.sendEmail = function(email) {

    // check if email has been configured
    var emailConfig = app.config.get("email")

hoodie.js is a library to abstract common backend tasks in form of frontend developer friendly JavaScript methods.

The API is what we care most about. No matter of how complex are behind the curtain, hoodie.js has to remain as simple as jQuery.

The current implementation is done with CoffeeScript, for reasons. But we want to move to make a proper JavaScript implementation and want to invite you to help us:

• what's your opinion on how the hoodie.js modules should be structured, the "JavaScript way"?
• what are libraries we should look into / learn from?
• this is your chance: do you want to help migrating hoodie.js to JavaScript? Raise your hand

// This is in response to https://gist.github.com/Peeja/5284697.
// Peeja wanted to know how to convert some callback-based code to functional
// style using promises.

var Promise = require('rsvp').Promise;

var ids = [1,2,3,4,5,6];

// If this were synchronous, we'd simply write:

  // In real life, you'd probably use more than just 2 workers,
  // and perhaps not put the master and worker in the same file.
  cluster.fork();
  cluster.fork();

  cluster.on('disconnect', function(worker) {
