The JBoss Polyglot Revolution - Be part of it!

In this talk, Galder will look at the evolution of JBoss, from a producer of java based middleware, to the current expansion towards multi-language platforms. How did Torquebox come about? Why are we creating Ceylon? What is Escalante? What is Immutant? This and many other questions will be answered in this informal chat that will not only look into the motivations behind building middleware in other languages, but will also discuss the technological advances that have this expansion possible. During this presentation the audience will get invaluable feedback on the lessons learnt while developing with other languages, pitfalls of the different languages used, tips of learning new languages...etc, giving them first-hand advice that they will be able to apply in their work environments. Finally, the talk will finish with information on how join and contribute to the JBoss Polyglot Revolution!

48. Richard Hamming, 1968 Turing speech Whereas Newton could say, "If I have seen a little farther than others, it is because I have stood on the shoulders of giants," I am forced to say, "Today we stand on each other's feet." Perhaps the central problem we face in all of computer science is how we are to get to the situation where we build on top of the work of others rather than redoing so much of it in a trivially different way.
