Beyond JUnit: Powertools for Test-Driven Development

Writing tests is more than just writing JUnit test cases and hoping that they'll pass when your project is built. If you want assurance that your code is sound and provides the desired functionality, then you'll want to test it from every angle and run those tests as frequently as possible.

Building Web Applications with Spring MVC

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.

Introducing Spring Roo: From Zero to Working Spring Application in Record Time

Watch Preview Video

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.

Modular Java: An Introduction to OSGi

Contrary to what you may have heard, OSGi is neither complex, nor heavyweight. In this session, I'll show you how OSGi can actually simplify application development rather than complicate it. We'll look at the benefits of modularity, the fundamentals of OSGi, and see how to develop basic OSGi bundles. We'll also see how a few gadgets in the OSGi toolbox can ease the development of OSGi bundles.

Modular Java: Declarative OSGi with Spring Dynamic Modules

This session will introduce you to Spring-DM. You'll learn how working with OSGi services can be as easy and as natural as declaring a in Spring. In addition, we'll look at how to use Spring-DM's web extender to develop modular web applications in OSGi. And we'll see how Spring-DM became part of the OSGi specification as Blueprint Services.

Prerequisite: Modular Java: An introduction to OSGi

What's new in Spring

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.

How to Approach Refactoring

You can't be agile if your code sucks. You know that you have to constantly refactor your code and design. But the questions is how? In this presentation, instead of looking at a laundry list of refactoring techniques, we will instead look at how to effectively approach refactoring and along the way discuss some core principles to look for.

Scala Tricks

Scala is a very powerful hybrid functional pure object oriented language on the JVM. Scala is known for its conciseness and expressiveness. In this presentation we will look at some common tasks you do everyday in developing applications and see how they manifest in Scala.

Tackling Concurrency on the JVM

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.

Testing with dependencies

Testing is a key ingredient to the success of a project. However, testing becomes awfully hard when your application deals with dependencies and that is often the reality.

Transforming to Groovy

Groovy is a elegant, dynamic, agile, OO language. I like to program in Groovy because it is fun and the code is concise and highly expressive. Writing code in a language is hardly about using its syntax, however. It is about using the right idioms. Come to this section to pick up some nice Groovy idioms.

Prerequisite: Some knowledge of Groovy is helpful but not required.

What's Brewing in Java

Java has come a long way, and yet there is so much that's happening in this space. In this presentation we will take a look at the exciting additions and changes coming up in the next version of Java.

Prerequisite: Good programming knowledge of Java

HTML 5 ... and the Kitchen Sink

HTML 5 is an adventurous and confusing prospect that will help change the Web as we know it. It is being finalized as a standard but won't be fully supported by most browsers for quite some time. Companies like Apple and Google have already committed to it as the future of Web application development, however. There are a huge number of new features, updates and gotchas coming at us (including the proverbial kitchen sink!) so it is time to get prepared. This talk will walk you through the new bits and try to put it all into perspective.

RDFA : Weaving Richness and Meaning in the Web

The human web is reasonably well in hand by now. We are getting pretty good at building systems that people find valuable and entertaining. We have not spent as much time concerned about our software friends. There is a ton a rich content available on the web that is too difficult to extract in automated ways using just XHTML, the meta tag and microformats. This talk will introduce you to some emerging technologies from the Semantic Web camp to enrich your web pages with useful information for both automated extraction and improved browsing experiences.

REST : Information-Driven Architectures for the 21st Century

There is a shift going on in the Enterprise. While still used and useful, the promises of the SOAP/WSDL/UDDI Service-Oriented Architecture (SOA) stack have failed to live up to their promise. A new vision of linked information is enveloping online and Enterprise users. The REST architectural style is squarely behind this thinking as a way of achieving low-cost, flexible integration, increased data security, greater scalability and long-term migration strategies.

If you have dismissed REST as a toy or are unfamiliar with it, you owe it to yourself to see what is so interesting about this way of doing things.

SPARQL : Querying the Web of Data

The human-friendly Web is about nicely-formatted, accessible content for users to browse. There are emerging Data Webs (both public and private) that rely on technologies from the Semantic Web stack to link increasingly rich connections between various data sources. SPARQL and RDF are the main tools for expressing and using this connectivity. This talk will introduce you to one of these topics and the practical and accessible aspects of employing them on the Web and in the Enterprise.

Getting people to come to consensus on common models and schemas is usually the hardest part of any data integration strategies. These technologies help lower the bar on both the technical and social costs of stepping up your integration strategies.

Semantic SOA : Meaningful Service Strategies

The goal for web services was always to reduce our burden by increasing the potential for reuse of business functionality. Somehow, we got lost along the way in a morass of confusing, unfulfilling and downright broken technologies.

While we are interested in pursuing REST-based systems for managing information, we need some strategies for tying it all together sensibly. If we abandon WSDL, SOAP and UDDI, what do we replace them with? This talk will walk you through combining resource-oriented strategies with technologies from the Semantic Web to describe, find, and bind to services in dynamic, flexible and extensible ways.

We will start to blur the distinction between data, documents, services and focus on information and how it is connected to what we already know.

Prerequisite: The Semantic Web: The Future Now, Give it a REST and SPARQL : Querying the Data Web would all be helpful talks to have attended

Hacking Your Brain for Fun and Profit

Watch Preview Video

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.

JavaScript Beyond the Basics

JavaScript is one of the most widely used languages around and yet its also one of the most misunderstood. With Ajaxified UIs becoming the norm, this humble language is once again at the forefront.

Testing the Web Layer

While your project might have nearly 100% code coverage on the server tier, many projects ignore testing the web layer. With more and more code being pushed to the browser, a lack of tests for the client code begs for trouble.

jQuery: Ajax Made Easy

Watch Preview Video

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.

Automated Software Quality Control Tools

This session is aimed at helping developers get started with automating the collection of software quality metrics. We'll cover continuous integration, automated code metrics gathering, and analysis of these metrics. The ability to be able to detect problems early, and also to write higher quality code early, helps avoid bugs and headache down the line. We'll cover some best practices around using and putting in tools to help achieve higher quality.

Easy mobile development (IPhone, Android, Palm Pre, Blackberry) without native code

So you have a great idea for an IPhone app, you've tried learning Objective-C, but it's just too hard. What about those other new platforms like Palm Pre and Android? Who wants to write the same app three times? Four times if you count Blackberry! Fear not, there is a much easier way for you to develop on the IPhone. Using a development style called "hybrid mobile applications" you can write apps for IPhone and other platforms using stuff you already know: HTML, CSS and Javascript. In this course, we'll go over the basics for hybrid development

Enterprise JPA & Spring 3.0 - Tips and Tricks for JEE Persistence

As with many technologies, the basics are easy. The hard part comes when the developer needs to do sophisticated integration, development, and testing as part of an enterprise application. A large enterprise application requires the developer to think of issues that affect the development, scalability and robustness of the application. This presentation will cover the advanced topics described below with a focus on the new persistence features in Spring 3.0 and JPA 2.0.

Real-world JEE performance troubleshooting & tuning: Tips n' Tricks

Performance tuning any application is a black art that can consume much time. Fortunately, Java has many tools that can aid in this effort. There also are a number of basic tips that can help to analyze and fix performance problems. The Java memory model is usually something that you don't need to tune, but for high performance applications it is necessary to tweak. While there are a number of advanced things that can be done to performance tune an application, we'll discover that the simple, basic things are all that are usually needed to make your apps fly.

Virtualization for development

We've all heard about virtualization for deploying applications. How about leveraging virtualization for development? In this session, we'll look at some time saving tips and build a virtual VM for development and testing.

Busy Java Developer's Guide to Advanced Collections

Once you've learned the core Collections clases, you're done, right? You know everything there is to know about Collections, and you can "check that off" your list of Java packages you have to learn and know, right?

Prerequisite: Busy Java Developer's Guide to Collections

Pragmatic Architecture

Watch Preview Video

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 Busy Java Developer's Guide to Collections

For so many Java developers, the java.util.* package consists of List, ArrayList, and maybe Map and HashMap. But the Collections classes are so much more powerful than many of us are led to believe, and all it requires is a small amount of digging and some simple exploration to begin to "get" the real power of the Collection classes.

The Busy Java Developer's Guide to Concurrency (Part 1: Threads)

Java's threading capabilities took a serious turn for the better with the release of Java5, thanks to the incorporation of the java.util.concurrent packages, a set of pre-built components for thread pooling and execution, synchronization, and more.

The Busy Java Developer's Guide to Concurrency (Part 2: Concurrency)

Java's threading capabilities have been a part of the Java platform since its inception, yet for many Java developers, using Threads still remain a dark and mysterious art, and synchronization beyond the use of the "synchronized" keyword is almost unknown.

Prerequisite: The Busy Java Developer's Guide to Concurrency (Part 1: Threads)

The Busy Java Developer's Guide to Functional Java

Much noise has been made in recent years about functional languages, like Scala or Haskell, and their benefits relative to object-oriented languages, most notably Java. Unfortunately, as wonderful as many of those benefits are, the fact remains that most Java developers will either not want or not be able to adopt those languages for writing day-to-day code. Which leaves us with a basic question: if I can't use these functional languages to write production code, is there any advantage to learning about them? The short answer is yes, for the fundamental premise--"I can't use functional code on my Java project"--is flawed. Java developers can, in fact, make use of functional ideas, and what's better, they don't even have to reinvent them for Java--thanks to the FunctionalJava library, many of the core primitives--interfaces that serve as base types for creating function values, for example--already exist, ready to be used.

The Busy Java Developer's Guide to Scala: Basics

Scala is a new programming language incorporating the most important concepts of object-oriented and functional languages and running on top of the Java Virtual Machine as standard "dot-class" files. Sporting the usual object-oriented concepts as classes and inheritance, Scala also offers a number of powerful functional features, such as algebraic data types, immutable objects by default, pattern matching, closures, anonymous functions and currying, and more. Combined with some deep support for XML generation and consumption, Scala offers Java programmers an opportunity to write powerful programs with concise syntax for a new decade of Java programming.

Agile Engineering Practices

Evolving towards REST-based Enterprise Integration

This talk describes an agile approach to architecture, and merges the current state-of-the-art thinking in both service oriented architectures(SOA) and web-based architectures like HTTP, REST, and hypermedia.

Keynote: Smithing in the 21st Century

Blacksmiths in 1900 and PowerBuilder developers in 1996 have something in common: they thought their job was safe forever. Yet circumstances proved them wrong. One of the nagging concerns for developers is how do you predict the Next Big Thing, preferably before you find yourself dinosaurized. This keynote discusses why people are bad at predicting the future, and why picking the Next Big Thing is hard. Then, it foolishly does just that: tries to predict the future. I also provide some guidelines on how to polish your crystal ball, giving you tools to help ferret out upcoming trends. Don't get caught by the rising tide of the next major coolness: nothing's sadder than an unemployed farrier watching cars drive by.

Testing the Entire Stack

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

Prerequisite: Confusion about what to test when and where

Visualizations for Code Metrics

Judicious use of metrics improves the quality of your code. But interpreting metrics presents a challenge. You have a list of numbers for a project - what does it mean? And what does it tell me about the health of the project overall? This sessions shows how to produce visualizations for software metrics, making them easier to understand and more valuable. It covers metrics at the individual method level all the way up to the overall architecture of the application. This isn't just a talk about how some tools produce visualizations: this session shows you how to generate your own visualizations, allowing you to customize it to the level in information density that shows real value on your project. I show how to produce projected graphs from dependencies, heat-maps for cyclomatic complexity and code coverage, using XSLT to extract visual information from XML configuration documents, and others. Metrics can't help you if you can't understand them. By creating visualizations, it helps leverage metrics to make your code better.

Aspect Oriented Programming With Spring AOP

Aspect-Oriented Programming (AOP) complements Object-Oriented Programming (OOP) by providing another way of thinking about program structure. The key unit of modularity in OOP is the class, whereas in AOP the unit of modularity is the aspect. Aspects enable the modularization of concerns such as transaction management that cut across multiple types and objects. (Such concerns are often termed crosscutting concerns in AOP literature.)

Compile Time and Runtime Metaprogramming With Groovy

The dynamic nature of Groovy makes it a fantastic language for building dynamic applications for the Java Platform. The metaprogramming capabilities offered by the language provide everything that an application development team needs to build systems that are far more capable than their all Java counterparts. Taking advantage of Groovy's metaprogramming capabilities brings great new possibilities that would be very difficult or just plain impossible to write with Java alone. Building Domain Specific Languages in Groovy is easy to do once a team has a good understanding of the Metaobject-Protocol (MOP) and the method dispatch mechanisms used by the Groovy runtime environment.

GORM Inside And Out

GORM is a super powerful ORM tool that makes ORM simple by leveraging the flexibility and expressiveness of a dynamic language like Groovy. With GORM developers get access to all of the power and flexibility of an ORM tool like Hibernate without any of the complexity.

Enterprise Security, Privacy and Data compliance

Data integrity, security, recovery, privacy and regulatory compliance are most important attributes for enterprise implementation. Enterprise customers ask for transparency in how the vendors will provide security programs. Many question need to be asked for any cloud implementation to policy makers, architects, coders and testers.

In this presentation we will explore data security and storage, privacy and data compliance issues. We will explore the security management in cloud. Presentation is useful for anyone starting from Executives to developers who are going to implement the enterprise Applications in both private and public cloud.

Enterprise testing to make your application foolproof

Enterprise software solutions are an essential part of many large enterprises. Given the critical role enterprise software solutions play, it is imperative that they are tested effectively and efficiently all the time. It is as important, if not the most important, as any other phase of the Software Development Lifecycle (SDLC). But testing an enterprise application is easier said than done. This presentation targets seasoned software developers, testers and project managers who are looking for guidance in implementing an effective application testing strategy. We will discuss the rationale behind application enterprise testing and explore building blocks of effective testing and explain their importance. Then we will explore how to do effective root-cause analysis. We will discuss the typical output of a performance test and how to perform effective analysis. We will learn the effects of particular software environments on testing. The approach is generic; so many details regarding your applications will depend on the characteristics of the technologies you use. Later on we will explore at two tools PushToTest and CloudTest to automatically test web applications. Attendees will learn different test strategies for testing.

Decision Making in Software Teams

Watch Preview Video

Alistair Cockburn has described software development as a game in which we choose among three moves: invent, decide, and communicate. Most of our time at No Fluff is spent learning how to be better at inventing. Beyond that, we understand the importance of good communication, and take steps to improve in that capacity. Rarely, however, do we acknowledge the role of decision making in the life of software teams, what can cause it to go wrong, and how to improve it.
