With the forthcoming release of Java7, a number of things come to fruition, both in the Java language and in the libraries, and it's important for Java developers to know what those features are, and how they change the game of writing Java code--or not.

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."

The full title of this talk reveals its grand aims: Game Theory and Software Development: Explaining Brinksmanship, Irrationality, and Other Selfish Sins

Once in a while, a topic, seemingly orthogonal to software development, presents a great opportunity to showcase how engineering can benefit from knowledge of seemingly more social disciplines. In this talk, the fundamental principles of economics' Game Theory are compared to often inexplicable behaviors and decisions we frequently observe in programming projects.

Programming concurrency has turned into a herculean task. I call the traditional approach as the synchronized and suffer model. Fortunately, there are other approaches to concurrency and you can reach out to those directly from your Java code.

Hadoop is a MapReduce framework that has literally sprung into the vernacular of "big data" developers everywhere. But coding to the raw Hadoop APIs can be a real chore. Data analysts can express what they want in more English-like vocabularies, but it seems the Hadoop APIs require us to be the translator to a less comprehensible functional and data-centric DSL.

The Cascading framework gives developers a convenient higher level abstraction for querying and scheduling complex jobs on a Hadoop cluster. Programmers can think more holistically about the questions being asked of the data and the flow that such data will take without concern for the minutia.

We'll explore how to set up, code to, and leverage the Cascading API on top of a Hadoop sample or production cluster for a more effective way to code MapReduce applications all while being able to think in a more natural (less than fully MapReduce) way.

Traditional collections on the Java platform focused on providing thread-safety at the expense of performance or scalability. More modern data structures strive to provide performance without compromising thread-safety. Some of them require you to adopt to a different semantics or programming model. In this presentation we will explore some data structures that can help reach both thread-safety and reasonable performance.

One of the first principles of lean software development is the elimination of waste. Shigeo Shingo identified seven types of manufacturing waste in his "A Study of the Toyota Production System." Later, the Poppendieck's translated these to seven wastes of software development.

The Java Virtual Machine is home to several different languages beyond Java, many of which mix ideas (paradigms) together to create a flexible language. Languages which support these different paradigms can be awkward and hard to understand how to use at first.

When it comes to cross cutting software concerns, we expect to have or build a common framework or utility to solve this problem. This concept is represented well in the Java world with the loj4j framework, which abstracts the concern of logging, where it logs and the management of logging. The one cross cutting software concern which seems for most applications to be piecemeal is that of security. Security concerns include certification generation, SSL, protection from SQL Injection, protection from XSS, user authorization and authentication. Each of these separate concerns tend to have there own standards and libraries and leaves it as an exercise for the development team to cobble together a solution which includes multiple needs.... until now... Enterprise Security API library from OWASP.

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.

JavaScript is one of those very powerful languages that is often misunderstood and underutilized. It's quite popular, yet there's so much more we can do with it.

"The Google Guava project contains a host of new features/classes for use by the Java programmer. Intended as a drop-in supplement for the standard JDK APIs, Guava provides features like immutable and forwarding collections, some concurrency utilities, more support for primitives, and so on.

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

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.

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.

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

Programmers often complain that it is hard to automate unit and acceptance tests for JavaScript. Testability is a design issue and with some discipline and careful design we can realize good automated tests.

Whether you are just getting started, or you’ve made an attempt and well… it could be better… a lot better, this session is for you. Ken has been working on Agile projects as a coach and mentor for a number of years. Come discover the common reasons teams fail to get it right. Bring your own challenges and lets discuss. This is set to be an engaging and illuminating discussion.

Scala is a statically typed, fully OO, hybrid functional language that provides highly expressive syntax on the JVM. It is great for pattern matching, concurrency, and simply writing concise code for everyday tasks. If you're a Java programmer intrigued by this language and are interested in exploring further, this section is for you.

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.

Android is a new mobile development platform, based on the Java language and tool set, designed to allow developers to get up to speed writing mobile code on any of a number of handsets quickly. In this presentation, we'll go over the basic setup of the Android toolchain, how to deploy to a device, and basic constructs in the Android world.

Cryptography at first seems like a daunting topic. But after a basic intro and the leverage of the Java Cryptography Extension (JCE), it seems downright feasible to add encryption and decryption capabilities to your application.

Developers weren't satisfied with just the JCE and its plug-in concepts though. Over the last few years, framework architects have made strides in either wrapping or re-writing the approachable JCE in more convenient APIs and fluent interfaces that make effective and accurate crypto down right simple.

Explore three of these libraries -- Jasypt, BouncyCastle and KeyCzar -- and how they can be leveraged to make your next Java cryptography and data security effort a simple exercise and not a tribulation.

Many development shops have made the leap from RCS, Perforce, ClearCase, PVCS, CVS, BitKeeper or SourceSafe to the modern Subversion (SVN) version control system. But why not take the next massive stride in productivity and get on board with Git, a distributed version control system (DVCS). Jump ahead of the masses staying on Subversion, and increase your team's productivity, debugging effectiveness, flexibility in cutting releases, and repository redundancy at $0 cost. Understand how distributed version control systems are game-changers and pick up the lingo that will become standard in the next few years.

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.

There is a new “movement” in software development circles called DevOps. It is about the automation of development best practices as well as the automation of the deployment pipeline. Answer this question, “How long does it take your organization or team to push 1 line code of change into production?” That’s what this session is all about.

With the rise of multi-core processors, and their growing ubiquity (on client machines, to say nothing of the server machines on which Java applications most frequently execute), the need to "program concurrently" has risen from "nice-to-have" to "mandatory" requirement, and unfortunately the traditional threading-and-locking model is just too complicated for most Java developers--even the brightest of the lot--to keep track of with any degree of reliability. As a result, numerous new solutions are emerging, each of them with their own strengths and weaknesses, leaving the Java developer in a bit of a quandary as to which to examine.

Git is a version control system you may have been hearing a bit about lately. But simply hearing more about it may not be enough to convince you of its value. Getting hands on experience is what really counts. In this workshop, you'll bring your Windows, Mac or Linux laptop and walk through downloading, installing, and using Git in a collaborative fashion.

People are confused about the status of HTML 5. Is it ready? Is it not? What is part of the spec and what isn't? We'll talk about the situation in the "HTML 5 and the Kitchen Sink" discussion, but as always, the proof is in the pudding. We will introduce the most exciting new features of HTML 5 and its related technologies and build examples that use them.

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?

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.

CoffeeScript is a little language that compiles into JavaScript. Underneath all of those embarrassing braces and semicolons, JavaScript has always had a gorgeous object model at its heart. CoffeeScript is an attempt to expose the good parts of JavaScript in a simple way.

The golden rule of CoffeeScript is: "It's just JavaScript". The code compiles one-to-one into the equivalent JS, and there is no interpretation at runtime. You can use any existing JavaScript library seamlessly (and vice-versa). The compiled output is readable and pretty-printed, passes through JavaScript Lint without warnings, and runs in every JavaScript implementation.

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.

Agile has matured to the point of mainstream success. Even large companies have discovered that it helps them build better quality software faster. But the agile practices that are mainstream today have been around for a long time. What is the next wave of innovation in the Agile world going to bring?

Want to use Groovy but don't have time to read all of Groovy in Action? This talk gives you a whirlwind introduction to its capabilities, from basic data types, Groovy strings, POGOs, collections, Groovy SQL, and the Groovy JDK.

The second 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.

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

Groovy was never intended to replace Java. Instead, it expands Java capabilities and makes developers' lives easier. In this presentation, we'll survey many ways to make your Java systems easier by adding Groovy.

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 fourth of 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.

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.

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.

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.

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.

Businesses are increasingly recognizing the value of connecting with their customers on a more personal level. Companies can utilize social networking to transition from "Big Faceless Corporation" to "Friend" by taking their wares to the online communities where their customers are. In this age of social media, those communities are found at social network sites such as Facebook, Twitter, and LinkedIn. In this session, you'll learn how to build applications that interact with the various social networks. We'll also look at Spring Social, a new feature in the Spring portfolio that enables integration with social networks in Spring-based applications.
