Leveraging functional programming in Scala at the core of our new platform's backend, making use of cutting-edge technologies.

In our hunt for ways to make better user matches, we experimented with collaborative filtering. Here’s what we discovered.

How do you define a Chatroulette user and create a log of their actions? We put several methods to the test.
