Implement Routing for Subdomains

Rails 3.0 introduced support for routing constrained by subdomains.

A subdomain can be specified explicitly, like this:

match '/' => 'home#index', :constraints => { :subdomain => 'www' }

JavaScript function hoisting by example

Below are many examples of function hoisting behavior in JavaScript. Ones marked as works successfuly print 'hi!' without errors.

To play around with these examples (recommended) clone them with git and execute them with e.g. node a.js

Notes on hoisting

(I may be using incorrect terms below, please forgive me)

Web fonts are pretty much all the rage. Using a CDN for font libraries, like TypeKit or Google Fonts, will be a great solution for many projects. For others, this is not an option. Especially when you are creating a custom icon library for your project.

Rails and the asset pipeline are great tools, but Rails has yet to get caught up in the custom web font craze.

As with all things Rails, there is more then one way to skin this cat. There is the recommended way, and then there are the other ways.

The recommended way

Here I will show how to update your Rails project so that you can use the asset pipeline appropriately and resource your files using the common Rails convention.

	module SaysHi
	def self.included(base)
	base.extend ClassMethods
	end

	module ClassMethods
	def hi_to
	@hi_to \|\|= ""
	end

	// WordPress stores the site URL in the database by default (which I have never
	// understood), and it's a pain to have to type out the UPDATE SQL or search in
	// phpMyAdmin to change it. This is a simple way to put the URL into
	// wp-config.php instead.

	// Note that you will still need to update any URLs that appear in the content,
	// especially when you copy a database from a development site to production:
