Applied AOP
Most people new to Aspect-Oriented Programming (AOP) are fed up with separation of concerns zealots explaining how great their techniques are at dealing with... logging. Ok, you get it. Logging is a cross-cutting concern that can be appropriately modularized. What else does AOP have to offer? A lot, it turns out. This talk will give an introduction to the motivations of AOP as well as a series of concrete examples drawn from enterprise and client side Java. Come learn how AspectJ-flavored AOP can begin to benefit you immediately either in development or production environments. Learn how to enforce architectural policies, find Swing threading issues, reduce the invasiveness of the Observer design pattern or even improve the reusability of your domain models. Now that Spring 2.0 provides support for AspectJ, the time has never been better to learn about these new (but backwards compatible) ways of thinking about building software.Give it a REST
As developers, we sometimes get to make choices about the technologies we use, sometimes not. We base these decisions on personal experiences, recommendations from others and a general sense of where the industry is going.Web Services have been all the rage for several years now. We have been told time and again that we should be building systems around them; as an industry, we've never been more confused. Perhaps it is time to Give it a REST.
RESTlet for the Weary
If you have started to take a look at REST as way of exposing web services or managing information spaces, you may be frustrated by the support offered by legacy containers. There is no direct support for REST concepts in the J2EE specs (yet). XML-based configurations are so 1990's. Come learn about Restlets, a little API that has caught the attention of many in the RESTafarian community.Prerequisite: Give it a REST (unless you are very comfortable with REST)
Resource-Oriented Computing w/ NetKernel : Software for the 21st Century
Imagine the simplicity of REST married to the power of Unix pipes with the benefits of a loosely-coupled, logically-layered architecture. If that is hard to imagine, it may because the architectures available to you today are convoluted accretions of mismatched technologies, languages, abstractions and data models.NetKernel is a disruptive technology that changes the game. It has been quietly gaining mind share in the past several years; people who are exposed to it don't want to go back to the tired and blue conventions of J2EE and .NET. Not only does it make building the kinds of systems you are building today easier, it does it more efficiently, with less code and a far more scalable runway to allow you to take advantage of the emerging multi-core, multi-CPU hardware that is coming our way.
Come see how this open source / commercial product can change the way you think about building software.
Rich Clients, Rich Data Part I : Linking
You hear a lot of talk about rich clients, but the richness they purport to provide is predicated on having access to rich data as well as a rich user interaction style. Without the right levels of abstraction, it is hard to address and link all of the data we have to care about these days. Additionally, the web sites that do support the notion of linking require you to publish your data into TheirSpace. Forget that. You want to be able to link publicly available information to sensitive information in YourSpace.Ever since we started doing relational joins, we've looked for ways to tie data together. The problem is, the relational model is a bit tired and doesn't move at the speed of the Net. We need schemes that integrate relational data, web pages, XML files, RSS feeds and various other sources of information.
Rich Clients, Rich Data Part II : Consuming

The Semantic Web is Dead! Long Live the Semantic Web!
Just as the world is feeling comfortable with the Web, Tim Berners-Lee et al inform us that what we have seen so far is just the beginning. His original plans at CERN were larger and grander. The Semantic Web is a vision of machine-processable documents and metadata to improve search, knowledge discovery and data integration and management. The only problem is that there is no such thing. There is no Semantic Web, just the Web we have that is increasingly semantics-enabled.Forget the hype. Come learn how the technologies of this vision are being used today on the Web and in the Enterprise by more people than you might think.
Viva La Javolution!
You're a good Java programmer. You understand the JDK libraries and how to use them. The problem is that many fundamental APIs don't take the bigger performance picture in mind. Garbage collection can end up killing your app if you aren't careful. Concurrency problems and contention can keep your well-intentioned software from leveraging modern hardware architecture that support multi-core and multi-cpu systems.Who knew that simply using the standard library code the way it was designed was opening you up for performance problems in your apps?
Don't worry, Javolution has your back.
What's Going On? : Complex Event Processing w/ Esper
We write very complicated software, don't we? In our systems, we detect when simple things happen. Customers log in, people buy things, a stock is sold at a particular price, inventory shifts locations... all of these events mean little things, but what about the larger picture? Complex events are particular patterns of simpler events that suggest something deeper is happening. Do you know how you'd discover these bigger picture occurrences? Come hear how the Esper open source software represents a new class of complex event processing (CEP) frameworks that can be added to even high volume, high transaction systems.Jeff Brown - G2One Vice President of Professional Services - Groovy and Grails Developer
A Thorough Introduction To Groovy
Groovy is an agile dynamic language for the Java platform. The language and its libraries bring many things to the table to ease the process of building applications for the Java platform. This session provides a detailed run through Groovy with lots of code samples to drive home the power of the language.Advanced Web Development With Grails
Grails makes web application development both fun and easy. This session dives beyond the basics to cover advanced details of Grails that bring the really exciting features to your applications.Prerequisite: Grails - Agile Web 2.0 The Easy Way
Agile Test Driven Development With Groovy
Dynamic languages bring a lot of interesting elements to the table for teams interested in doing Test Driven Development (TDD). Groovy lends itself very well to TDD and this session demonstrates many features of the language and its libraries that help teams build more testable systems and build better tests.Grails - Agile Web 2.0 The Easy Way
Grails is a full stack MVC framework for building web applications for the Java platform. Grails makes web application development both fun and easy. This session covers all of the fundamentals of building web applications with Grails.Powerful Metaprogramming Techniques With Groovy
Metaprogramming is a key component in building truly dynamic and flexible applications with Groovy. Groovy's metaprogramming capabilities bring great new possibilities to the table that would be very difficult or just plain impossible to write with Java alone. This session will demystify a lot of the magic that seems to be going on inside of a Groovy application.Prerequisite: A Thorough Introduction To Groovy
Ken Sipe - Technology Director, Perficient, Inc. (PRFT)
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.Architecture and Scaling
Scale... what is scale... how do you applications which are scalable. How do you know if the application scales?Hacking - The Dark Arts
A live Hacking demonstration exposing the tools and techniques used by Hackers.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?SOAs Challenges
SOA... Is it hype? What's real... and what's not? What is the right abstraction level?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.Nathaniel Schutta - Author, speaker, software engineer focused on user interface design.
Designing for Ajax, part 1
So you've convinced the boss that your new web application just has to have Ajax...but now what? With dozens of libraries making even the most blinkish of interactions trivial, how do you decided where to sprinkle the magic Ajax dust? This talk will give a plain old boring "web 1.0" an Ajax facelift with a focus on improving the user experience providing you with a game plan for introducing Ajax to your world.Designing for Ajax, part 2
We'll pick up where Part 1 left off working in even more advanced approaches such as offline support with Google Gears.JavaScript: the Good, the Bad, and the Ugly
Thanks to Ajax, JavaScript is cool again and developers are taking a second look at this much maligned language. This session will give you an overview of this misunderstood language as well as opening your eyes to some of the excellent tools available to ease the pain of developing in this dynamic language.Test Infecting the Legacy Organization
When starting a new project, most developers make sure that testing is a priority. However, only the lucky few live in the idyllic world of greenfield development; the vast majority of us must contend with code written when "test" was a four letter word and testing was the sole responsibility of that "other" organization. We'll examine some techniques for introducing testing - not just to your code but to the rest of your development organization.Venkat Subramaniam - Founder of Agile Developer, Inc.
Acceptance Testing Application Behavior
How do you ensure your applications meet the expectations of your key customers? In this session we will explore using the FIT tool and Behavior Driven Design tools to do exactly this.Caring about your Code Quality
We all have seen our share of bad code. We certainly have come across some good code as well.What are the characteristics of good code? How can we identify those? What practices can promote
us to write and maintain more of those good quality code. This presentation will focus on this
topic that has a major impact on our ability to be agile and succeed.
Design Patterns in Java and Groovy
You're most likely familiar with the Gang-of-four design patterns and how to implement them in Java. However, you wouldn't want to implement those patterns in a similar way in Groovy. Furthermore, there are a number of other useful patterns that you can apply in Java and Groovy. In this presentation we'll look at two things: How to use patterns in Groovy and beyond Gang-of-four patterns in Groovy and Java.FP on JVM
Functional Programming Languages (FPLs) have been around for a long time. A lot of features that we get excited aboutin dynamic languages are common place in FPLs. FPLs are gaining importance due to various changes in our industry. What's exciting is that you can use them on the JVM. In this presentation we will dig into the details of what makes FPLs so interesting and look at ways to use them on the JVM?in your Java projects.
Know your Java?
Java has been around for well over a decade now. It started out with the goal of being simple.Over the years, its picked up quite a bit of features and along comes complexity. In this presentation
we will take a look at some tricky features of Java, those that can trip you over, and also look at some
ways to improve your Java code.
Practices of an Agile Developer
You have worked on software projects with varying degree of success. What were the reasons for the success of your last project? What were the reasons for those that failed? A number of issues contribute to project success - some non-technical in nature. In this presentation the speakers will share with you practices in a number of areas including coding, developer attitude, debugging, and feedback. The discussions are based on the 2007 Jolt productivity award winning book with the same title as the talk.Tools to facilitate Agile Development
The first item in the Agile Manifesto reads that we must prefer "people and interaction over process and tools."Given a choice between average people with superior tools and superior people with average tools, you are likely
to achieve greater success with the latter. However, it is important to be continuous and not be episodic?so you
want to get continuous feedback about the state, health, and quality of your code and application. Tools can
help us a great deal to realize this and make us productive.
Towards an Evolutionary Design
A good design is critical for success with agile development.That does not mean a big up-front design. The design has to
be evolutionary. However, the design you evolve must be
extensible and maintainable. After all, you can't be agile
if your design sucks.
