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.

After almost a decade and several significant releases, Spring has gone a long way from challenging the then-current Java standards to becoming the de facto enterprise standard itself. Although the Spring programming model continues to evolve, it still maintains backward compatibility with many of its earlier features and paradigms. Consequently, there's often more than one way to do anything in Spring. How do you know which way is the right way?

The first in a series of talks that are part of an arc covering next-generation information-oriented, flexible, scalable architectures. The ideas presented apply to both external and internal-facing systems.

Interested in HTML5? Want a change to play around with the latest and greatest in web app development? This workshop is for you! We'll cover feature detection, web forms, the new HTML elements, take a spin around the canvas, and we'll finish up with offline/local storage and web sockets.

This half-day workshop will bring you up to speed on the specifics of the Groovy programming language. We'll touch on most of the major features of the language, from collections and closures to builders, AST transformations, and metaprogramming. Specific examples will cover topics from Groovy itself and will be supported by unit and integration tests and built using Gradle.

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.

For a long while, we've built applications pretty much the same way. Regardless of the frameworks (or even languages and platforms) employed, we've packaged up our web application, deployed it to a server somewhere, and asked our users to point their web browser at it.

But now we're seeing a shift in not only how applications are deployed, but also in how they're consumed. The cost and hassle of setting up dedicated servers is driving more applications into the cloud. Meanwhile, our users are on-the-go more than ever, consuming applications from their mobile devices more often than a traditional desktop browser. And even the desktop user is expecting a more interactive experience than is offered by simple page-based HTML sites.

With this shift comes new programming models and frameworks. It also involves a shift in how we think about our application design. Standing up a simple HTML-based application is no longer good enough.

The word just came down from the VP - you need a mobile app and you need it yesterday. Wait, you've never built a mobile app...it's pretty much the same thing as you've built before just smaller right? Wrong. The mobile experience is different and far less forgiving. How do you design an application for touch? How does that differ from a mouse? Should you build a mobile app or a mobile web site? This talk will get you started on designing for a new, and exciting, platform. Whether that means iPhone, Android, Windows Phone or something else, you need a plan, this talk will help.

A Technology Radar is a tool that forces you to organize and think about near term future technology decisions, both for you and your company.

The Spock framework brings simple, elegant testing to Java and Groovy projects. It integrates cleanly with JUnit, so Spock tests can be integrated as part of an existing test suite. Spock also includes an embedded mocking framework that can be used right away.

This session starts with a high-level look at all that the Spring Data project has to offer. Then we'll dive deeper into a few select Spring Data modules, including Spring Data Neo4j, Spring Data MongoDB, Spring Data Redis, Spring Data JPA, and Spring Data JDBC Extensions

Mobile is the next big thing and your company needs to there. But what does there actually entail? Should you build a native app? On which platforms? Do you have the skills for that? What about the web? Can you deliver an awesome experience using nothing but a mobile web browser? This talk will help you navigate these treacherous waters. We'll discuss the pros and cons of the various approaches and give you a framework for choosing.

Computer science is built on a shaky tower of abstractions, but we've been distracted by other things until we believe it is reality.

Getting software released to users is often a painful, risky, and time-consuming process. This workshop sets out the principles and technical practices that enable rapid, incremental delivery of high quality, valuable new functionality to users. Through automation of the build, deployment, and testing process, and improved collaboration between developers, testers and operations, delivery teams can get changes released in a matter of hours–sometimes even minutes–no matter what the size of a project or the complexity of its code base.

You're all over jQuery - you write plugins in your sleep - and before that, you were a Prototype ninja. Your team treats JavaScript like a first class citizen, you've even written more tests than Kent Beck. Is that all there is in the land of the JavaScript developer? Believe it or not, the JavaScript party hasn't stopped. What other libraries are out there? What do they offer? This talk will survey the field of modern JavaScript libraries getting you up to speed on what's new. We'll dive in just deep enough to whet your appetite on a wide variety of libraries such as Backbone, Underscore, Zepto and more.

Even with the recent explosion in alternative languages for the JVM, the vast majority of us are still writing code in "Java the language" in order to put bread on the table. Proper craftsmanship demands that we write the best Java code that we can possibly write. Fortunately we have a guide in Joshua Bloch's Effective Java.

In this session, we'll start with the basics of Spring MVC development, focusing on how to leverage the new annotation-driven model. With that foundation set, we'll continue by exploring the new features in Spring 3.0 and 3.1 to build RESTful web applications that can serve both human-facing content as well as resources that are consumed by machine clients.

In this session, I'll show you how to secure your Spring application with Spring Security 3.0. You'll see hot to declare both request-oriented and method-oriented security constraints. And you'll see how SpEL can make simple work of expressing complex security rules.

The fifth in a series of talks that are part of an arc covering next-generation information-oriented, flexible, scalable architectures. The ideas presented apply to both external and internal-facing systems.

It's been ages since you copied random JavaScript off a nameless webpage and your JavaScript is every bit as elegant as any server side code. You know the ins and outs of jQuery and you've even built a plugin or three...but is that it? How do we build rich web applications without resorting to heavy weight proprietary components? How do we leverage HTML5 and everything it brings to the table? How do we craft elegant user experiences that integrate fully with the RESTful web services that are all the rage on the backend? How do we build apps that are at home on a 3.5 inch phone as they are on the 15 inch notebook? This talk goes beyond jQuery to explore new libraries like Backbone are bringing even more to the front end developer's toolbox.

Object-oriented programming was formally introduced in the 1970's with the advent of Smalltalk. C++ took it mainstream in the 1980's, and Java carried it to the next level in the 1990's. Unfortunately, if you examine the vast majority of Java codebases, what you'll find is a bunch of C-style structs (a.k.a. JavaBeans) and functions. As these codebases grow, a number of design smells can potentially crop up, which in turn cripple our ability to respond to change. We need SOLID principles that we can apply to keep our software clean and malleable.

In this session, we'll look at OAuth, focusing on OAuth 2, from the perspective of an application that consumes an OAuth-secured API as well as see how to use OAuth to secure your own APIs.

The Web is changing faster than you can imagine and it is going to continue to do so. Webs of Documents are giving way to machine-processable Webs of Information. We no longer care about data containers, we only care about data and how it connects to what we already know.

Perhaps the concepts of the Semantic Web initiative are new to you. Or perhaps you have been hearing for years how great technologies like RDF, SPARQL, SKOS and OWL are and have yet to see anything real come out of it.

Whether you are jazzed or jaded, this workshop will provide you with the understanding of a technological tidal wave that is heading in your direction.

Successful projects require any number of practices but if you don't know who you're building it for or what you're supposed to build, failure is a distinct possibility. How do we capture the who and what? Personas and story maps are two effective techniques that you can leverage. After discussing the basics, we'll break into small groups and you'll have a chance to actually try building a set of personas as well as a story map.

What is the DevOps movement? It a nutshell, it is the idea that the days of silos are over. Development, QA, and operations can no longer be thought of as separate warring divisons with their own "turfs." Instead, we must focus on the fact that we are all part of a single value stream for the customer. By collaboration and shared expertise, we can find real overlaps between our previously segregated areas of expertise and optimize that value stream.

In this session, we'll start with an empty directory and use Spine.js to create an interactive client-side web application. Then we'll leverage what we learned to build a mobile web application with a native feel that can be deployed either through a phone's web browser or via native wrapper frameworks such as Apache Cordova (aka, PhoneGap).

Chef is a community-developed platform for automated provisioning, configuration, and integration of software infrastructure. It currently boasts 190+ individuals and 40+ companies (including parent company OpsCode) as contributors, and companies like EngineYard, ElectronicArts, GoTime, and Rhapsody as adopters.

Chef achieves fully automated infrastructure via three primary disciplines:

• Automated provisioning of bare metal, virtualized, and cloud environments
• Configuration of servers via roles ("webserver", "appserver", "loadbalancer") and recipes, which are declarative descriptions of resource (e.g. Apache, MySQL, Hadoop) configurations written in a Ruby DSL
• Systems integration via dynamic lookup and discovery

Learning the syntax of a new language is easy, but learning to think under a different paradigm is hard.

Google “MongoDB is Web Scale” and prepare to laugh your tail off. With such satire, it easy to pass off MongoDB as a passing joke… but that would be a mistake. The humor is in the fact there seems to be no end to those who parrot the MongoDB benefits without a clue. This session is about getting a clue.

Technology changes, it's a fact of life. And while many developers are attracted to the challenge of change, many organizations do a particularly poor job of adapting. We've all worked on projects with, ahem, less than new technologies even though newer approaches would better serve the business. But how do we convince those holding the purse strings to pony up the cash when things are "working" today? At a personal, how do we keep up with the change in our industry?

Of all the non-functional requirements of software development, complexity receives the least attention and seems to be the most important from a long term standard point. This talk will look at some of forces that drive complexity at the code level and at a system level and their impact. We will discuss what causes us to over look complexity, how our perception of it changes over time and what we can do about it?

Puppet is a powerful framework for the automation of tasks typically performed by system administrators as part of software infrastructure provisioning and maintenance. Puppet adoption is rapidly increasing, boasting use by companies such as Google, RedHat, Constant Contact, Zynga, and Shopzilla.

Puppet is composed of three principle components:

• a declarative language for expressing system configuration,
• a client and server for distributing it,
• and a library for realizing the configuration

Why is Clojure the best new language on the JVM? Come to this session and see why this functional, dynamic Lisp is the best thing on the JVM since Java.

Poorly designed web applications fail to serve both the business and the users, leading to a unnecessary costs, and frustrated customers. By keeping the user in mind, and following a few simple guidelines, you can make huge leaps in the way your users interact with your applications.

Build processes are a pain point in most organizations. Ant is mature but very low level, Maven is powerful but hard to customize, and so on. The Gradle project brings the power and flexibility of Groovy to build files and processes.

Feature requests are steadily pouring in, but the team cannot respond to them. They are paralyzed. The codebase on which the company has "bet the business" is simply too hard to change. It's your job to clean up the mess and get things rolling again. Where do you begin? Your first task is to get the lay of the land by applying a family of techniques we'll call "Code Archaeology."

As a web application developer, most of the focus is on the user stories and producing business value for your company or clients. Increasingly however the world wide web is more like the wild wild web which is an increasingly hostile environment for web applications. It is absolutely necessary for web application teams to have security knowledge, a security model and to leverage proper security tools.

Build a Grails application from start to finish in this half-day workshop. We'll start with domain classes, apply constraints, add controllers and services, apply both unit and integration tests, and then add additional functionality through plugins.

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.

One of the hallmarks of lean software development is the elimination of waste. Several of the key wastes in software development revolve around incomplete, incorrect, or obsolete documentation, especially documentation of requirements. One effective means of ensuring that your requirements documentation is complete, correct, and up-to-date is to make it executable. That sounds nice, but how do we get it done, especially in the world of modern, cross-browser web applications?

You are a JavaScript developer who has gotten past writing one-off scripts on pages and wants to leverage the true power of the language. You have tasted the power of objects, and inheritance in Java, and hope to put the same to work for you in JavaScript.
