Java SwingBuilder is an attempt to bring dynamic language-type productivity to Java Swing UI development by defining the layout/event wiring/binding in a separate YAML file and leaving the Java class to focus on pure business-side code. Inspired by Groovy SwingBuilder (the concept in general), Ruby on Rails (YAML is the new JSON/XML, but leaner) and GTK+ libGlade (for the idea of keeping layout and event wiring in a separate file). End goal of the project: to define max content with the least amount of code.

When designing our API and our deployment model, we purposely went with P2P architecture because we wanted to have ultimate freedom on how a grid node is used. As a result, in GridGain a node can act as master or worker or both, depending on your configuration. Moreover, you don't even have to change a single line of code to get this to work.
