+title: "Let's Have Fun With WebRTC! - Part 1"
 description: WebRTC is a new technology that allows peer-to-peer media communication. It is fast (it relies on UDP), it is secure (all payload is encrypted -mandatory), and the best, simplest APIs have been implemented in web browsers, so all of this is available right now, without the need of any external softwares or plugins! In this series of articles, we will build some cool applications together to demonstrate the power of WebRTC!

 description: Docker is the new hype these days. Claiming to replace virtual machines, it promises faster delivery times, better software separations, reproducible development -and production- environments. This first post aims at presenting Docker, the concepts of containers, the differences between Docker and virtual machines, and lay the basics for the following posts.

 description: In this second article, it's about time we began playing with docker commands. We will begin by seeing how to install docker, and then we will cover the fundamentals. This is very important because everything else will rely on the good understanding of Docker fundamentals / terminology.
