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. Cryptography is quickly becoming a developer's new frontier of responsibility in many data-centric applications.

In this session, I'll lead a guided tour through the latest that Spring has to offer. Whether you're a Spring veteran or a Spring newbie, there will be something new for nearly everyone.

Emergent design is a big topic in the agile architecture and design community. This session covers the theory behind emergent design and shows examples of how you can implement this important concept.

In this example-driven session we'll see how to swiftly develop Spring applications using Spring Roo. We'll start with an empty directory and quickly work our way up to a fully functioning web application. You'll see how Roo handles a lot of heavy-lifting that you'd normally have to do yourself when working with Spring. And we'll stop at a few scenic points along the way to see how Roo accomplishes some of its magic.

This talk covers testing the entire stack: unit, integration, functional, behavior-driven, databases, user acceptance, mocking & stubbing, and other topics and strategies.

Most of the time when people talk about agile software development, they talk about project and planning practices and never mention actual development practices. This talk delves into best development practices for agile projects, covering all of its aspects.

Sure, Ajax might not be the hardest thing you'll have to do on your current project, but that doesn't mean we can't use a little help here and there. While there are a plethora of excellent choices in the Ajax library space, jQuery is fast becoming one of the most popular. In this talk, we'll see why. In addition to it's outstanding support for CSS selectors, dirt simple DOM manipulation, event handling and animations, jQuery also supports a rich ecosystem of plugins that provide an abundance of top notch widgets. Using various examples, this talk will help you understand what jQuery can do so you can see if it's right for your next project.

In this presentation we will take a quick walk though the issues with concurrency and how the solutions provided in Scala and Clojure help address those.

Building an application is not the straightforward exercise it used to be. Decisions regarding which architectural approaches to take (n-tier, client/server), which user interface approaches to take (Smart/rich client, thin client, Ajax), even how to communicate between processes (Web services, distributed objects, REST)... it's enough to drive the most dedicated designer nuts. This talk discusses the goals of an application architecture and why developers should concern themselves with architecture in the first place. Then, it dives into the meat of the various architectural considerations available; the pros and cons of JavaWebStart, ClickOnce, SWT, Swing, JavaFX, GWT, Ajax, RMI, JAX-WS, , JMS, MSMQ, transactional processing, and more.

For the last few years, the web has been all a-twitter about web 2.0 (and even the occasional reference to web 3.0.) Yes, the days of static web applications are officially over and while libraries like jQuery and Prototype make it easier to build modern applications, ultimately they are papering over issues in the web standards (and the browsers that implement them.) Today we're building to standards that are from the paleolithic era of web design but that's changing - and HTML 5 is a large part of that. In this talk, we'll discus just what HTML 5 is and why it matters. We'll show how you can build to HTML 5 today and which browsers support what. Thankfully, after many years of stagnation, the future of web applications looks bright!

The single most important tool in any developers toolbox isn't a fancy IDE or some spiffy new language - it's our brain. Despite ever faster processors with multiple cores and expanding amounts of RAM, we haven't yet created a computer to rival the ultra lightweight one we carry around in our skulls - in this session we'll learn how to make the most of it. We'll talk about why multitasking is a myth, the difference between the left and the right side of your brain, the importance of flow and why exercise is good for more than just your waist line.

Fred Brooks said, "How do we get great designers? Great designers design, of course." So how do we get great architects? Great architects architect. But architecting a software system is a rare opportunity for the non-architect.

The kata is an ancient tradition, born of the martial arts, designed to give the student the opportunity to practice more than basics in a semi-realistic way. The coding kata, created by Dave Thomas, is an opportunity for the developer to try a language or tool to solve a problem slightly more complex than "Hello world". The architectural kata, like the coding kata, is an opportunity for the student-architect to practice architecting a software system.
