OAuth Provider Service and Rails 3
I am trying to look into setting up an OAuth Provider Server with Rails 3 but can't seem to find anything out there to accomplish this. I am also a newb when it comes to oauth, so excuse my ignorance. When setting up an oauth server do I need to already have an oauth account at somewhere like agree2.com?

Ruby on rails: Devise, want to add invite code?
Hi, I would like to add an invite_code requirement for users to sign up. Ie. in addition to requiring them to specify an email/password combo, I want an additional field :invite_code. This is a temporary fix so that non-wanted users cannot login during a given alpha period. I'm confused since Devise doesn't add controllers. I'm sort o...
Disabling ActiveModel callbacks
I published an article on disabling ActiveModel callbacks, but I’m not completely sure this is the prettiest way to do something like this. Mongoid::Timestamps adds a before save callback that updates the updated_at field. Let's say I don't want that in some cases and I disable the callback like this: class User # I'm using Mongoid, ...

When and when not to stub/mock a test
I am making a concerted effort to wrap my head around Rspec in order to move towards more of a TDD/BDD development pattern. However, I'm a long way off and struggling with some of the fundamentals: Like, when exactly should I be using mocks/stubs and when shouldn't I? Take for example this scenario: I have a Site model that has_many :b...

Ruby/Ruby on Rails vs PHP
We do not get much projects in Ruby, we are so far focused only on PHP. As a web development agency are we missing an important channel of revenue due to our unopened nature with Ruby and Ruby on Rails?

How to tell Terminal which version of Ruby to use?
Hello, I have two related questions that I was hoping someone could help out with. I recently installed Ruby 1.9.2 on my Mac (running Snow Leopard 10.6.4) and I haven’t been able to figure out how to get Terminal to use the new Ruby as a default, rather than the factory-installed Ruby 1.8.7.
