Treasure Island - Railsberry 2012 - Krakow. Talk about concurrency in Ruby and JRuby in particular. Ruby is pretty unique among scripting languages in having not only one but six (!) fairly mature runtime environments -- MRI, Rubinius, JRuby, MacRuby, IronRuby and MagLev -- each of them with specific strengths. In this talk I will first give a brief overview of planet Ruby and its continents. Then we will embark together on a journey into the deepest concurrency jungles on Java island, where strange beasts like Kilim, Jetlang and Akka roam. With a little luck, we might even encounter the legendary Disruptor! Using examples taken from actual production JRuby code, I will demonstrate how the power of the JVM plus the rich ecosystem around it are an ideal complement to the expressiveness of Ruby -- and how this killer combination can be used to fully exploit modern multicore hardware. Speakers: Tim Lossen, Patrick Huesler

Slides from my talk at RubyConf India 2012. This is a case in point for a highly productive & scalable enterprise application development platform with JRuby on Rails. When we started to architect an enterprise micro-blogging solution as part of the internal collaboration platform for a large customer (henceforth referred by dummy name ’CustCollab’), the next immediate question was “Which web application development framework to use?”. Simplicity, productivity, ability to deliver high quality of service (QoS), especially performance & scalability, & alignment with CustCollab’s technology stack were our top criteria for framework selection. After considerable research on state-of-the-art, we zeroed in on 2 frameworks – 1) “Ruby on Rails” (RoR) for its super simplicity & productivity & 2) “Java Enterprise Edition” (JEE) for its obvious “enterprise” class, high QoS & greater alignment with CustCollab’s technology stack. But we just couldn’t rule out either one, since each framework had been proven to deliver qualities not so proven in the other framework. Naturally, we started dreaming of a framework which can deliver best of both worlds! And in reality, there lived such a framework – ’JRuby on Rails’! In this talk I will focus more on our experience of how JRuby, & hence JRoR, has done a fantastic job of delivering best of RoR & JEE worlds to an enterprise application w.r.t multiple ’quality of service’ attributes like scalability (parallel processing, Garbage Collection, compilation, caching, advanced database connection pooling etc.), productivity, extensibility, security (especially CSRF), session management, reusability, total cost of ownership (alignment with existing/preferred technology stack) etc. With the help of the real world ’CustCollab Micro-blogging’ case in point, this presentation demonstrates how the distant, isolated worlds of RoR & JEE can synergize with the help of the JRuby bridge to result in a highly productive & scalable enterprise application development platform. I hope it encourages others to adapt JRuby, & hence Ruby, in the enterprise. After all, as promised by the JRuby dev. team, the JRuby improvisation is well capable of delivering the best of both Java & Ruby worlds, & hence deserves greater attention in the enterprise world!
