Today's world of parallel and distributed computing poses hard new challenges for software development. A rapidly increasing number of developers now have to deal with races, deadlocks, non-determinism, and we are ill-equipped to do so. How can we keep things simple, in spite of the complexity of the underlying runtimes?
JRuby is just a Ruby implementation for the JVM, right? Wrong! JRuby has gone well beyond other language implementations by supporting arbitrarily-encoded strings, native library calls, reloadable applications, and much more. This talk will explore how JRuby is pushing the JVM and Java platform in new directions, and how you can take advantage of this new power.
One theme of Programming Android is that Android is now client Java. Client Java is what every Java coder started with when they start learning Java, but then, when it gets down to working for a living, it's all server Java now. So you have millions of coders who are primed for a successful client Java, and many of them work in enterprise IT. How will Android impact the work of Java coders?

Writing a compiler used to be a big deal. Nowadays, we have an abundance of good tools to help us: parsing frameworks, bytecode generators, and rich runtimes. In this introductory talk, we’ll see how to design and implement a rudimentary compiler in about half an hour for a simple programming language on the JVM.

Ever wondered whether you should use a weak reference or a phantom reference? If you answered "yes" or "phantom who?," this is the talk for you. Walk in with a working knowledge of the language, and walk out an expert in references, referents, reclamation and other garbage collection necromancy.

The power of enterprise Java is now available through the expressiveness of Ruby. More and more projects are suited to new technologies and frameworks such as Ruby on Rails. Using TorqueBox, a team's members can leverage their knowledge, investments, skills, and trust in Java while exploring the cutting edge of new development models.
Securing your applications can be a painful and confusing process, but it doesn't have to be. Apache Shiro simplifies all aspects of application security without sacrificing power or flexibility. Les Hazlewood, Apache Shiro PMC Chair, will explain all of Shiro's core features and demonstrate how to easily secure your own application- from small mobile to large enterprise applications.

Learn how to build a simple JVM compiler with Scala's parser combinators and Apache's BCEL.
The Android SDK is open source and developed transparently. Although not well known, this is just the tip of the iceberg. There is a huge variety of development, test and build tools available. You can reuse some existing Java libraries and will find that more and more Android specific libraries are being created and used. Get a good overview and see what the future might bring.
You've written applications for the JVM, using various frameworks and maybe even various languages. You understand how to rig up the CLASSPATH, get .class files to load, compile source, and set up an IDE. But you've always wanted a better understanding of the plumbing underneath. How does JVM bytecode work? What happens to bytecode after you hand it off to the JVM?

Visage is the successor to the JavaFX Script Language, a domain-specific language for writing UIs. It excels at rapid application design and can be used on any platform that supports Java. In this lab you will have an opportunity to write Visage applications that deploy to and run on Android mobile devices. No prior experience with Android or Visage development is required.
