We just launched a side-project we have been building over the last couple of months -- Coderoulette is a pair programming game for developers, like a Chatroulette for hackers.

We match developers in real time and give them coding challenges they have to solve doing pair programming using a collaborative IDE and video conference.

You can check it out here: https://www.coderoulette.com/

We also published an article explaining how we built it. I'd love to hear your feedback.
