Basic Concepts: Brian Pontarelli on Google Guice Dependency Injection

This presentation covers the latest dependency injection framework named Guice. Guice was written by the developers at Google and makes dependency injection lighter, faster and easier to write. Unlike other dependency injection frameworks, Guice uses annotations and Java code for configuration rather than XML. Like most of the projects from Google, Guice is extremely fast and can create large object graphs in milliseconds. Guice supports the most common dependency injection concepts, but in a type safe manner and without the XML.

The topics we'll cover during this presentation are

- Guice Modules
- Guice annotations
- Custom annotations
- Injecting and supporting legacy code
- Multiple implementations of an interface
- Injecting constants
- Injecting statics
- Scopes
- Aspect Oriented Programming

To round out the discussion, we'll compare Guice to the Spring and look at the differences for common day-to-day tasks.

Advanced Concepts: Andrig Miller from RedHat/JBoss: JBoss Enterprise Application Platform Tuning

In this presentation, I cover tuning the JBoss Enterprise Application Plaform (sometimes still called JBoss Application Server).  Along with that, I also cover basic performance tuning practices, Linux specific tuning (which can also be applied to all major OSes), and database and storage performance tuning.
