In April Matz released a new implementation of the Ruby language called MRuby. MRuby allows developers to embed Ruby in other programs. This talk will give you an overview what MRuby is, what can be done with MRuby and what not. And we will have a closer look at our approach of embedding Ruby in the open source NoSQL database ArangoDB. We will introduce some real life use cases, ready to hear if this approach is nonsense in your point of view or may help you building better applications in a shorter period of time.
