We first want to take a look at what versions are installed for a given formula, brew info FORMULA. Let's take a look at the versions of Redis that are installed.

@czq. ➜  Formula rvm:() git:(master) brew info redis
redis 2.4.5
http://redis.io/
/usr/local/Cellar/redis/2.4.4 (9 files, 460K)
/usr/local/Cellar/redis/2.4.5 (9 files, 460K) *

Retaining line numbers with the Rails asset pipeline

By default the Rails 3 asset pipeline uses the Uglifier gem to optimize and minify your Javascript. One of its many optimisations is to remove all whitespace, turning your Javascript into one very long line of code.

Whist removing all the newlines helps to reduce the file size, it has the disadvantage of making your Javascript harder to debug. If you've tried to track down Javascript errors in minified Javascript files you'll know the lack of whitespace does make life harder.

Luckily there is a simple solution: to configure Uglifier to add newlines back into the code after it performs its optimisations. And if you're serving your files correctly gzip'd, the newlines add only a small increase to the final file size.

You can configure Uglifier to add the newlines by setting the following in your Rails 3 config/production.rb file:

	module JasmineFixtures
	extend ActiveSupport::Concern

	module InstanceMethods

	# Saves the markup to a fixture file using the given name
	def save_fixture(name)
	response.should be_success
	fixture_path = File.join(Rails.root, '/spec/javascripts/fixtures')
	fixture_file = File.join(fixture_path, name)

	// Media Queries in Sass 3.2
	//
	// These mixins make media queries a breeze with Sass.
	// The media queries from mobile up until desktop all
	// trigger at different points along the way
	//
	// And important point to remember is that and width
	// over the portrait width is considered to be part of the
	// landscape width. This allows us to capture widths of devices
	// that might not fit the dimensions exactly. This means the break
