Rate limiting with Redis

June 2011 - Chris O'Hara - (archived original post)

Rate limiting can be an effective way of conserving resources and preventing automated or nefarious activities on your site.

A common use case is to limit the amount of requests an IP can make over a certain time frame. For example, you might want to restrict users from using an expensive search utility on your site. If the user attempts to search more than 5 times a minute, you can redirect them to another page informing them that they need to wait.

IP based rate limiting is already in use on larger sites. Google and Yahoo both employ the technique to prevent (or at least complicate) automated requests to their services.

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.

        return getHashValue()
