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.

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Mac OS X 10.9 Mavericks

Custom recipe to get OS X 10.9 Mavericks running from scratch, setup applications and developer environment. I use this gist to keep track of the important software and steps required to have a functioning system after a semi-annual fresh install.

Install Software

The software selected is software that is "tried and true" --- software I need after any fresh install. I often install other software not listed here, but is handled in a case-by-case basis.

      "This is a **software development story** from early in my career. The company in question went bust eighteen years ago, so it’s probably safe to tell the tale now.1 When I had interviewed for the job, the interviewer had explained that I was needed to work on their JavaScript engine. The company was a web development tools startup, and they had spotted that it would be a good idea to have JavaScript code running on the server as well as on the client, so that you could share your business logic and validation code between the client-side and server-side parts of your application. There are now lots of products in this space but twenty years ago was probably too soon for this to be a success. Anyway, the interviewer told me that the JavaScript engine was nearly done, but there were one or two features that were missing, and it was running a bit slowly, so I might have to do a bit of optimization. Sure, I said, that sounded like it would
