		<description><![CDATA[In this presentation, Bob Lee the CTO of Square Inc discusses where Java comes from and where it is heading. According to him, the main driver is scalability and throwing more hardware is not the solution. He discusses also JRuby, Android, invokedynamic, closures and how open Java is.

		<description><![CDATA[In this video, JRuby core team members will give you a tour of the codebase, showing how JRuby parses Ruby code, implements Strings and other core classes, and eventually compiles and optimizes JRuby code on the JVM. You&#8217;ll learn how to debug JRuby, profile performance or memory hotspots, implement extensions in Java or Ruby, and ultimately how to contribute back to JRuby.

		<description><![CDATA[RedBridge is a nickname of embedding API included in JRuby. Using Ruby from Java is another feature of JRuby as well as using Java from Ruby. With JRuby’s RedBridge, RubyGems becomes one of the choices to build a Java application. This means JVM languages can also choose RubyGems to create an application.

		<description><![CDATA[In the same manner that Matz Ruby has C extensions, JRuby has Java extensions. Even though JRuby lets you use existing Java classes directly from Ruby you may still want to write a pure Java extension. This could be to have a higher performing ruby class or to make an existing Java class library more &#8216;ruby-esque&#8217;. My use case was to provide a seamless API for the Hitimes gem across all ruby engines. This talk will cover the facets of building Java extensions for JRuby and the burgeoning support for ...]]></description>

		<description><![CDATA[The discussion about JRuby has for a long time been focused on “Bringing Ruby to the Java World” – but no longer! With the release of “jruby-jars” – a gem containing a runnable version of JRuby available to any platform – the conversation has shifted. We’ll look at how akephalos uses jruby-jars to bridge MRI and HtmlUnit (a pure Java library), and how you can start using JRuby today as a part of your MRI stack.

		<description><![CDATA[One major benefit of JRuby is the ability to import Java classes and use them as if they were POROs (Plain Old Ruby Objects). This feature makes Java fun again. You can pull in legacy code and sculpt an API which fits nicely into your Ruby code. You can even access novel and unrivaled Java libraries to do something not currently possible in the Ruby world. This video shows basics of interacting with Java classes from within Ruby, point out Gotchas and gives style hints to make Java APIs fit ...]]></description>

		<description><![CDATA[Today writing portable Web applications that can use the power of the Comet technique is almost impossible: Tomcat, Jetty, and Grizzly/GlassFish application server all have their own set of private APIs. Atmosphere leverages and builds on Project Jersey and the Java API for RESTful Web Services (JAX-RS). Jersey is the open resource reference implementation of JAX-RS that makes it easier to build RESTful Web services. Atmosphere and Jersey complement each other, with the goal of making it easier to build Comet-based Web applications that include a mix of Comet and ...]]></description>

JRuby is everywhere, bringing Ruby to new users and new domains every day. In this session, we&#8217;ll show many other examples of JRuby, from mobile devices to games to desktop apps to cloud computing to new Java integration features.

		<description><![CDATA[As web developers, we live in an arranged marriage with JavaScript. What is a Rubyist to do? Use JavaScript as a compile target? Abstract it away on the server? With JRuby, we can embrace the shared language of the web in a compelling way, building reusable libraries that work across the client-server boundary. By bridging Ruby to JavaScript using Rhino, we gain shared databases, including their indexing strategies. We gain remote model discovery and shared client/server validation. We gain a shared query language. And because it is JavaScript, we gain ...]]></description>

We begin by describing some applications we&#8217;ve developed for App Engine, including implementation of other languages, such as JRuby, on top of the App Engine for Java implementation. These implementations demonstrate the breadth of capability provided by App Engine. We then examine some of the strengths and current weaknesses that we encountered. We also describe more about the implications for testing that arise when ...]]></description>

Running JRuby on top of Google App Engine for Java gives access to many interesting possibilities, including running Rails on top of Google&#8217;s infrastructure. Exactly how to make this happen is not totally apparent, though, and there are several gotchas involved in the process. This presentation will introduce the pieces of JRuby needed to get everything working, what kind of customizations are needed, what you might need to avoid in Ruby to avoid getting in trouble with App ...]]></description>
