This session will survey a wide range of tools across the Java space. We'll look at utilities such as VisualVM, jstatd, jps, jhat, jmap, Eclipse Memory Analyzer, jtracert, btrace and more.

Open Source is not just a suite of libraries you consume within your application, but now reaches into the space of tools to help you troubleshoot and improve your applications. The price of these tools eliminates barriers to their use and their open source nature allows you to mix and match them into compositions that work well for your application's unique debugging needs.

These tools will help you peel away layers of your application to expose bugs and performance ceilings. We'll interactively analyze the heap and garbage collection cycles of both local and remote applications, take snapshots of heap, query the heap for heavy usage, leaks and augment running code without a reboot and without breaking a sweat. After attending, you'll never look at Java debugging the same way again.

Does your application transmit customer information? Are there fields of sensitive customer data stored in your DB? Can your application be used on insecure networks? If so, you need a working knowledge of encryption and how to leverage Open Source APIs and libraries to make securing your data as easy as possible. Encryption is quickly becoming a developer's new frontier of responsibility in many data-centric applications.

In today's data-sensitive and news-sensationalizing world, don't become the next headline by an inadvertent release of private customer or company data. Secure your persisted, transmitted and in-memory data and learn the terminology you'll need to navigate the ecosystem of symmetric and public/private key encryption.

Developers are looking for venues to present at these days for the education of the community and betterment of their career. The goal may be to present at a conference, user group, or just a private company. Learn the techniques of the best presenters in the industry through a dissection of what it takes to efficiently construct an engaging talk that offers solid insights and is memorable for the audience.

This talk provides tips, techniques, examples, and references: In short, a complete boot camp for building presentations that will capture the hearts and minds of an audience. This talk is largely tool-agnostic and you can use these techniques in Apple Keynote, Microsoft PowerPoint, or OpenOffice Impress. Specific points covered include stock photos, mind maps, presentation techniques, topic selection and diagramming.

Explore what's new on the cutting edge release of Maven, version 3.0. We'll explore the performance improvements, features that make debugging Maven issues easier, and changes to POMs that may require modifications to your build, but will result in more determinate build outputs.

Maven 3.0 has undergone major refactorings, and correspondingly, a battery of backwards compatibility tests to ensure a smooth transition from Maven 2.0. These refactorings prepare Maven for the next several years of development, including the separation of the POM file language from from the POM in-memory processor, which is already leading to Groovy, Ruby and YAML based POM file parsers.

You've heard about Git, Mercurial, Bazaar and the Distributed Version Control System revolution. In this deeply hands on session, we'll load Git on participants laptops, build repositories and share out pieces of work. We'll explore the optimized agile workflows that Git facilitates, building branches for each story card and merging with our team mates, even when a network isn't present. We'll clone an existing Subversion repository, work on it in a Git fashion, and push just the "good changes" back to Subversion, showcasing the incredibly polished interoperability of this radical source code control tool.

This will be a hands on session and requires attendees to bring a laptop (Windows, Linux, or Mac).
