                15 Questions to Ask During a Ruby Interview
              
          
    Originally published in June 2008
When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first.  In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written.  And in the corporate/enterprise world, I often don't have access to their previous work.
To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.
What to expect

Candidates will typically give you a range of responses based on their experience and personality.  So it's up to you to decide the correctness of their answer.

                Simple Authentication in Rail 4 Using Bcrypt
              
          
    #Simple Authentication with Bcrypt
This tutorial is for adding authentication to a vanilla Ruby on Rails app using Bcrypt and has_secure_password.
The steps below are based on Ryan Bates's approach from 
Railscast #250 Authentication from Scratch (revised).
You can see the final source code here: repo. I began with a stock rails app using rails new gif_vault
