Rails flash messages with AJAX requests

original: http://stackoverflow.com/a/10167659/656428

This is just a jotting of notes on how to embed Faye into a single Rails process. Makes it nice to do simple real time things without the need for a separate Faye server/process.

Also uses Faye Redis to work across load balanced Rails apps.

You also need to copy the compiled javascript into vendor/assets/javascripts and include into application.js manifest.

Ignore the numbers in the file names... just used to add order to the Gist.

This uses the faye/faye Github repo at edc5b42f6560d31eae61caf00f6765a90e1818d1 since I wanted to use with the Puma rack server and that is only available in the master branch (until Faye 1.0)

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.
