#HTML presentation tools
There are many HTML presentation tools and they are all created for slightly different reasons. Here's an overview. Please let me know if I forgot any.

RGBToBin = function(r,g,b){ | |
var bin = r << 16 | g << 8 | b; | |
return (function(h){ | |
return new Array(25-h.length).join("0")+h | |
})(bin.toString(2)) | |

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written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.
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.
There are many different provisioning tools out there, the most popular of which are Chef and Puppet. Chef uses Ruby, Puppet uses a DSL (Domain Specific Language), there are others that use simple bash too, but today we're going to focus on Chef Solo.
To get Chef working properly on your local machine you need a few things.
Make sure you use Ruby 1.9.x and not Ruby 2.x as you will get errors with the json 1.6.1 gem on 2.x. Use rbenv or RVM to manage several different Rubies on the one machine.

Let's have some command-line fun with curl, [jq][1], and the [new GitHub Search API][2].
Today we're looking for:
Multi-series line chart rendered using React and D3.
// === Arrays | |
var [a, b] = [1, 2]; | |
console.log(a, b); | |
//=> 1 2 | |
// Use from functions, only select from pattern | |
var foo = () => [1, 2, 3]; |
On the Refinery29 Mobile Web Team, codenamed "Bicycle", all of our unit tests are written using Jasmine, an awesome BDD library written by Pivotal Labs. We recently switched how we set up data for tests from declaring and assigning to closures, to assigning properties to each test case's this
object, and we've seen some awesome benefits from doing such.
Up until recently, a typical unit test for us looked something like this:
describe('views.Card', function() {
