With Java supporting lambda expressions, we have nothing to stop us from creating functional style of code for our day to day applications. We're so used to object-oriented programming, but remember the paradigm shift we went through to adapt to that way of programming. It is yet another paradigm shift and most of us wonder how in the world can we write functional style code. Much like how OO was not as much about the syntax as it was about the design, functional programming is about the design, the idioms, and the data structures we'd use to program.

In this hands-on workshop, we will learn about functional programming using practical examples, create small apps that will make use of this style of programming, and relate to how it differs from the traditional way we're used to and the benefits it offers.

Now that Java is supporting lambda expressions, it's time to hone our skills to make use of them. Lambda expressions can help create concise code, however, it takes more than learning the syntax to put them to good use.

In this presentation we will learn the idiomatic use of lambda expressions, explore the ways in which we can use them to solve common tasks, and look into libraries and APIs that make use of them in Java.

Invoke dynamic is a Java 7 feature that had the most impact at the bytecode level and also in terms of performance. First perceived as a feature to help dynamically typed languages on the JVM, it turned into a powerful feature that has been exploited quite a bit in the implementation of features in the Java language itself.

In this presentation we will understand what problem this features really solves and how it has influenced other features in the Java language and on the Java platform.

There is a good amount of excitement about the new version of Java. The big evolution of course is the lambda expressions. In this presentation we will dive into the language features in Java 8, take a look at some of their nuances, and look at ways to put them to good use.

Java 8 language capabilities and application.

Relational databases have ruled the world since the dawn of time (or so it appears). They power our enterprises and for many in the corporate world, it may be hard to imagine life without them. Each decade a novel idea would challenge the status quo and make a case to deviate for the tradition. A flock of enthusiastic programmers, like your humble speaker back in the early 90s, would throw their support around it, only to be crushed eventually by the large vendors and enterprise standards. But, the excitement around NoSQL has shown that enterprise data is not the only thing that's persistent.

In this presentation we'll learn how NoSQL deviates from those deep rooted traditional approaches, and how this may be useful. We will also discuss the situations where these types of databases may be more appropriate.

Languages offer a lot more than syntax and compilers. They often have supporting libraries and special facilities that set them apart from other languages. Some languages offer special compiler support for a particular construct, like tail call optimization, for example. Others provide interesting library support or capabilities.

In this presentation we will dive into 12 cool things we can do with different languages on the JVM, things that are either impossible or hard to do in Java, but are quite easy and useful to realize in other popular languages on the JVM. If mixing these languages is an option on your projects, you'll have dozen more reasons after this presentation.

We've been told to keep things simple. It turns out, that's easily said than done. Creating something simple is, well, not really that simple. If simple was sitting next to us, would we even recognize it? Is my design simple, is yours simple? How can we tell?

That's a simple question, but the answer to it is... well come to this talk to find out.

Developing a rich user interface for web applications is both exciting and challenging. HTML 5 has closed the gaps and once again brought new vibe into programming the web tier. Come to this session to learn how you can make use of HTML 5 to create stellar applications.

User experience and rich interaction is top in the list of things that influence the success and adoption of applications. Such richness and interactions were owned by desktop and native applications in the past. Over the recent years the web has become increasingly interactive, but the true richness was still lacking. But all that has changed with HTML 5 canvas and animation techniques.

Come to this session to learn how to create rich interactive applications with good animation, mouse and touch based interactions.

Mobile devices are gaining popularity but the diversity of these devices poses a challenge for development. HTML 5 promises to bring a consistent API to program the client side for both desktop and diverse mobile devices. One additional challenge with mobile devices is network connectivity, or the lack of it. Mobile devices are often taken into remote areas with low or no connectivity. While a native app can run on the device anytime, a web based application by default depends on having connectivity, unless of course we use the offline capabilities of HTML 5. Come to this presentation to learn how to create applications that can switch seamlessly between connected and offline mode.

Learn about offline options, configurations, local storage and how to program all of that, in this highly interactive, live coding session.

Multiple languages on the JVM offer the ability to write concise and expressive code. One thing that sets Groovy apart, more distinctively than a few others, is its ability to extend the program at runtime. Classes are open in Groovy and we can not only add methods, but we can synthesize methods as well, at runtime. This ability provides for quite an interesting set of flexibilities, paving the way to create highly dynamic applications, domain specific languages, lightweight configurable components, all with less code.

In this workshop we will dive into metaprogramming in Groovy, using practical hands-on examples and make use of it to create some dynamic behavior. We will focus on concepts and techniques you can readily put to real use on your next project.

When I got into Java I had a "Wow, look how easy it is to implement these patterns." When I got into Groovy, I had the same reaction, but only better. The dynamic nature of Groovy makes it easier to implement some common patterns. What's better, there are some patterns that you can exploit in Groovy that are not so easy in Java. In this section, you will learn how to implement some traditional patters in Groovy, and also other patterns you are simply not used to in Java.

This presentation will go far beyond the Gang-of-four (GOF) patterns. You will learn how to implement some GOF patterns, but also some patterns that will allow you to exploit dynamic nature of Groovy and the elegance of Groovy closures.
