class Module
  # Provides a delegate class method to easily expose contained objects' methods
  # as your own. Pass one or more methods (specified as symbols or strings)
  # and the name of the target object as the final :to option (also a symbol
  # or string).  At least one method and the :to option are required.
  #
  # Delegation is particularly useful with Active Record associations:
  #
  #   class Greeter < ActiveRecord::Base
  #     def hello()   "hello"   end

/* Simple spam protection for email addresses using jQuery.
 * Well, the protection isn’t jQuery-based, but you get the idea.
 * This snippet allows you to slightly ‘obfuscate’ email addresses to make it harder for spambots to harvest them, while still offering a readable address to your visitors.
 * E.g.
 * <a href="mailto:foo(at)example(dot)com">foo at example dot com</a>
 * →
 * <a href="mailto:foo@example.com">foo@example.com</a>

In celebration of Whyday: Rubyists always want to show others the beautiful code 
they have created, hence the question: Has Anybody Seen My Code?

Has Anybody Seen My Code
(sung to the tune of Has Anybody Seen My Gal)

Clean and small, works for all,
Ruby is my all in all.
Has anybody seen my code?

Ubuntu 12.04 Ruby on Rails Development Environment

I haven't set up an install guide for the latest ubuntu release, largely because the last set of instructions worked pretty closely with the latest and greatest Ubuntu, 12.04 Precise Pangolin, however when installing today, I found that there were enough differences in the way that I configure my setup to justify an update, so here it goes. Yes, I'm late to the party, but a quick google search didn't find anything that I felt was as complete for my requirements as my previous install guides, so here I go.

As always with my install guides, I have included here is just about everything you'll need (and then some) to get started with ruby on rails development with Ubuntu 12.04 as a platform. These are my settings and preferences, and this is certainly not the only way of doing things, so keep that in mind.

Step 1: Get the repos ready and run updates.

sudo apt-get update && sudo apt-get upgrade
