Presentations
Java Memory, Performance and the Garbage Collector
You are using Java, whew!!! No need to worry about memory, the garbage collector will handle that. Those who have had a memory issue in Java are not so naive any more. Often memory utilization and heap sizes are an after thought and are not recognized until the application is in production, often caused by application uptime, production request volume or production sets of data. When the OutOfMemory Error occurs, often the science of development seems to brake down and knobs are turned. First the (-mx) maximum heap space gets adjusted… More is better right. The next OutOfMemory, heads start scratching, code reviews start in earnest, and Google gets several new hits. Did you know that it is possible to get an OutOfMemory error without running out of heap space?
Hacking - The Dark Arts
A live Hacking demonstration exposing the tools and techniques used by Hackers.
Spring 2.5 - Spring without XML
Spring 2.5 is brand spanking new, with a number of fantastic features. With growth of large and complex Spring applications which struggle with xml manageability and with the added pressure of Guice and SEAM there is a push for less XML, with solution leaning towards annotations. Spring 2.5 adds to the toolset provided in Spring 2.0 to provide a development environment where XML is greatly reduced… or eliminated if you so choose.
Spring+JPA+Hibernate: Standards Meeting Productivity for Java Persistence
Well the standards created EntityBeans…. yea. and the community created Hibernate. Fortunately the standards body learned some lessons and created JPA. JPA requires a vendor implementation and none make a better choice then Hibernate. Combined with Spring this trio is a powerhouse when it comes to developer productivity on applications requiring persistence.
JMX and Spring: Manageability for Spring-based Applications
This session describes management of Java resources using the Java Management Extensions JMX API. JMX provides a unified framework to instrument Java systems with monitoring and management capabilities.
7 Habits of Highly Effective Developers
Thoughts lead to words, words lead to action, actions lead to habits. In this session we'll sharpen the development saw in the process of understanding what makes a hyper-productive programmer. The focus will consist of developer habits and development processes.
