We will kick off this meetup with a talk on "JRuby+Truffle: A faster but simpler new Ruby" by Dr Chris Seaton, followed by two talks on "Doing Things Differently at Reevoo" by Jonny Arnold and "Continuous Feedback" by Chris Blackburn.
JRuby+Truffle is a new Ruby interpreter from Oracle Labs. While it uses cutting-edge compiler technology to achieve high performance, the concepts and implementation of most of JRuby+Truffle are actually rather simple - simpler than MRI, JRuby or Rubinius, and needing only techniques that can be explained in a few slides.
Dr Chris Seaton is a Research Manager at the Virtual Machine Group in Oracle Labs, where he leads the work to implement Ruby using the next generation of Java Virtual Machine technology, and other projects.
Reevoo is already an Agile company: we have JIRA Agile, so we must be, right? A few months ago we set out on a greenfield project, and decided to do things differently. What would happen when we went back to sticky notes and whiteboards for planning? Could we deliver on time for a project if we never set a deadline? And what happens when half of the development team changes every two weeks? Come along to our public retrospective on what went well and what we would never do again.
Jonny has been gradually going south for the last 7 years. Following a degree in physics from Durham University, he has spent the last 4 years developing alternative skills as a software developer in Stevenage and then London. Now currently working at Reevoo, he can often be found rambling at great volume about software architecture, productivity and karaoke.
