1. Clone your fork:

git clone [email protected]:YOUR-USERNAME/YOUR-FORKED-REPO.git

2. Add remote from original repository in your forked repository:

cd into/cloned/fork-repo
git remote add upstream git://github.com/ORIGINAL-DEV-USERNAME/REPO-YOU-FORKED-FROM.git
git fetch upstream

Here's how this works:

• Include a git_hooks/ directory in your project, with these two files (plus other hooks if you want, written in a similar style).
• Add "npm" to your devDependencies in package.json, so that the pre-commit hook can do its magic.
• Add test and lint scripts to your package.json, e.g.

    "scripts": {
        "test": "mocha",
 "lint": "jshint ./lib --show-non-errors"

// example function where arguments 2 and 3 are optional
function example( err, optionalA, optionalB, callback ) {

    // retrieve arguments as array
    var args = [];
    for (var i = 0; i < arguments.length; i++) {
        args.push(arguments[i]);
    }

    // first argument is the error object

Let's say you have an iOS project, and you want to use some external library, like AFNetworking. How do you integrate it?

With submodules

Add the project to your repo:

git submodule add [email protected]:AFNetworking/AFNetworking.git Vendor/AFNetworking

or something to that effect.

Advanced SCSS

Or, 16 cool things you may not have known your stylesheets could do. I'd rather have kept it to a nice round number like 10, but they just kept coming. Sorry.

I've been using SCSS/SASS for most of my styling work since 2009, and I'm a huge fan of Compass (by the great @chriseppstein). It really helped many of us through the darkest cross-browser crap. Even though browsers are increasingly playing nice with CSS, another problem has become very topical: managing the complexity in stylesheets as our in-browser apps get larger and larger. SCSS is an indispensable tool for dealing with this.

This isn't an introduction to the language by a long shot; many things probably won't make sense unless you have some SCSS under your belt already. That said, if you're not yet comfy with the basics, check out the aweso
