Ye Olde Learn Un*x The Hard Way Shortcut

GOAL

Be able to push to Heroku as any of three Heroku users from a single computer and a single user.

For this, you will not be allowed to copy and paste anything - except SSH keys themselves, because we're not THAT evil.

If you get error messages, read them carefully, and make note of what you understand, what you don't understand, and what you think you understand.

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.
