JRuby+Truffle is a new high performance implementation of Ruby being built as an open-source research project at Oracle Labs. It uses state-of-the-art research into techniques for writing interpreters and dynamic compilers that allows it to be both significantly faster than any other implementation of Ruby, but also conceptually simpler.

In this talk we'll explain how JRuby+Truffle works. We'll cover the whole system from the parser to emitting the actual machine code bytes - and we won't have to leave our Java IDE to do it.

We won't shy away from technical depth where it's needed to uncover all the details, but Truffle is designed to be a high-level and simple system accessible to non-experts. Novices will get an insight into the big ideas, and experts will be able to find out how it all really works.
