Geb is a Groovy based framework for automated acceptance testing of web applications - think "Selenium on steroids". Learn about how Geb uses the Page model to make acceptance tests less brittle and strategies for getting the maximum value out of your acceptance tests.
Testing is a great way to introduce Groovy into an organization. It allows you to try out the language without having to change your production environment. Spock is the premier Groovy based testing framework for developing elegant, powerful tests - quickly and efficiently.
Domain Specific Languages can provide an order of magnitude productivity benefit when used properly. Learn how to refactor from a traditional API through internal DSLs to external DSLs and how to handle real world requirements like IDE support, testing and DSL evolution. In this session we'll show how you can refactor a language from an API all the way to an external DSL in less than a day.
Some apps are little more than CRUD. The interesting projects are those with essential complexity in the domain. In this presentation we'll show how ideas from Domain Driven Design, Domain Specific Modeling and Domain Specific Languages can be used to more effectively design, refine and maintain the code at the heart of complex applications.
In just 90 minutes, we'll install Gradle and develop a range of build scripts. Whether you're just looking to improve your builds or to create sophisticated project automation scripts, get some hands-on experience with the framework that won a Springy at SpringOne2GX for "Most Innovative Product/Project".
What's the point attending a conference unless you do something with the knowledge you gain? In this session we look at practical strategies for selecting new technologies and proven approaches for driving adoption back at the office.
Prerequisite: Frustration that you don't get to use all the cool technologies you learn about at No Fluff.
"What will it cost?" "When will it be done?". Unfortunately, almost a decade after the agile manifesto was written, these are still questions we have to answer on a regular basis.
In this session we'll cover a range of practical techniques for improving your requirements gathering and increasing the accuracy of your project estimates while also setting realistic expectations for your project stakeholders based on practical experience in specifying, quoting and delivering over four hundred applications over the last ten years.
Prerequisite: Previous experience with missing a milestone or blowing an estimated budget!
Tim Berglund - GitHubber
Want to go deep on a popular NoSQL database? Cassandra is a scalable, highly available, column-oriented data store in use at Netflix, Twitter, Reddit, Rackspace, and other web-scale operations. It offers a compelling combination of a rich data model, a robust deployment track record, and a sound architecture, making it a good choice of NoSQL databases to study first.
Prerequisite: None, but NoSQL Smackdown! would be helpful preparation.
Some systems are too large to be understood entirely by any one human mind. They are composed of a diverse array of individual components capable of interacting with each other and adapting to a changing environment. As systems, they produce behavior that differs in kind from the behavior of their components. Complexity Theory is an emerging discipline that seeks to describe such phenomena previously encountered in biology, sociology, economics, and other disciplines.
Take one ugly legacy schema, a toolbox full of simple database refactorings, and a world-class schema refactoring tool, and you've got 90 minutes of workshop that will equip you to bring a culture of database responsibility to your team.
Prerequisite: Database Refactoring with Liquibase
Most teams manage database change using an ad-hoc system of SQL migration scripts manually applied to various development, staging, and production servers. Some even contrive automated processes, but rarely does this surplus build engineering deliver value directly to the customer. We should be writing applications, not build tools.
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.
You love Groovy and you're a believer in cloud computing. For a larger project you might choose Grails and hosting on Amazon EC2, but what if you want to take advantage of the nearly massless deployments of a cloud provider like the Google App Engine? You could make Grails work, but it's not always the best fit. Enter Gaelyk.
You've read that the relational model is old and busted, and there are newer, faster, web-scale ways to store your application's data. You've heard that NoSQL databases are the future! Well, what is all this NoSQL stuff about? Is it time to ditch Oracle, MySQL, and SQL Server in favor of the new guard? To be able to make that call, there's a lot you'll have to learn.
Neal Ford - Application Architect at ThoughtWorks, Inc.
Domain Specific Langauges seems like a cool idea, but where's the payoff? This talk provides an overview of how to build both internal and external DSLs (including the state of the art tools), stopping along the way to show how this is practical to your day job.
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.
Prerequisite: Having worked in an organization that values bureaucracy more than individuals
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?
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.
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.
Prerequisite: understanding of architectural and design concepts
Matthew McCullough - Head of Training, GitHub
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.
Prerequisite: A very basic knowledge of MapReduce and Hadoop
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.
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.
Prerequisite: Basic understanding of Subversion or similar version control system
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.
Prerequisite: Basic knowledge of a version control system. Subversion knowledge is a plus, but not imperative.
This session will survey a wide range of tools across the Java space. We'll look at utilities such as VisualVM, jstatd, jps, jhat, jmap, Eclipse Memory Analyzer, jtracert, btrace and more.
Open Source is not just a suite of libraries you consume within your application, but now reaches into the space of tools to help you troubleshoot and improve your applications. The price of these tools eliminates barriers to their use and their open source nature allows you to mix and match them into compositions that work well for your application's unique debugging needs.
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.
Prerequisite: Basic understanding of cryptography (hashing, symmetric, asymmetric)
You're serious about improving the quality of your code base, but with 10,000 lines of code, where do you start and how do you ensure the greatest ROI for the re-work your team members will perform?
Sonar is an open source tool that brings together the best of breed static and dynamic analysis of Java projects. The result is a unified view of problematic areas of your code on a time-line basis, allowing the team to attack the problems with the best ROI, and maintain a more watchful eye for positive and risky trends in the codebase in the future.
Prerequisite: Basic familiarity with Ant, Maven or Gradle builds and a desire to measure the quality of your code base.
Ted Neward - Enterprise, Virtual Machine and Language Wonk
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.
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.
Games? What do games have to do with good business-oriented applications? Turns out, a lot of interesting little tidbits of user-interface, distribution, and emergence, found normally in the games we play, have direct implications on the way enterprise applications can (or should) be built.
"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.
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.
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.
"From Wikipedia: "A physics engine is computer software that provides an approximate simulation of certain simple physical systems, such as rigid body dynamics (including collision detection), soft body dynamics, and fluid dynamics, of use in the domains of computer graphics, video games and film. Their main uses are in video games (typically as middleware), in which case the simulations are in real-time. The term is sometimes used more generally to describe any software system for simulating physical phenomena, such as high-performance scientific simulation."
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.
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.
Nathaniel Schutta - Author, speaker, software engineer focused on user interface design.
Some developers assume that agility and usability are mutually exclusive - in reality, they are extremely complimentary; if you squint, you might have a hard time telling the difference between agile practices and good user interface design. This usability talk is aimed squarely at developers giving you the tools you need to develop UIs that won't make your users yack. We'll discuss the importance of observation, personas, paper prototyping, usability testing and the importance of good moderators. In addition, we'll map the various aspects of user interface design to a typical agile iteration.
The word just came down from the VP - you need a mobile app and you need it yesterday. It needs to be polished and have that design stuff too. Oh and it needs to be on all the major platforms in time for the big marketing push next month. After a moment of panic, you wonder if it's too late to become a plumber but don't worry, there's hope! More and more developers are falling in love with the "write less do more" library and for good reason; it simplifies the job of today's front end engineer. But did you know jQuery could also help you with your mobile needs as well? That's right, jQuery Mobile is a touch optimized framework designed to provide a common look and feel across a wide variety of today's mot popular platforms. In this session, we'll take a look at all that jQuery Mobile has to offer and we'll convert a native application to an HTML5, jQuery Mobile masterpiece.
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.
Brian Sletten - Forward Leaning Software Engineer
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.
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.

Today's web application developers and testers have a host of options at their disposal for building automated user acceptance tests. This session will be a "shootout" of sorts between several of the popular available frameworks:
You've got your build automated using Ant/Maven/Gradle and you're building and running your unit test suite every time you check-in. That's easy. In fact, with Jenkins you can do this in under 5 minutes.
However, if we want to move beyond "mere" Continuous Integration to Continuous Delivery, there are many other areas in which we need to achieve "push button" automation. This talk will survey many of these areas and tie everything together with an integrated case study at the end.
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.
Kanban. What is it? It is most certainly not just moving sticky notes around on a board. Far from that, it is a method for gradual, evolutionary improvement of existing software processes. That's right, existing software processes. There is no "Kanban Development Process." Think you're "doing Kanban?" Think again.
Venkat Subramaniam - Founder of Agile Developer, Inc.
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.
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.
Quite a few languages have raised to prominence on the JVM. A frequently asked question is "How do I integrate my Java code with these?" This session answers that very specific question.
Keynote on lessons we can learn from our civilizations and evolution.
Scala, the hybrid functional, fully object-oriented language has evolved over the years. In this presentation we will talk about what has changed in this language in the recent release and look at some cool things you can do with this very powerful language.
Automated functional testing is very critical to ensure the code we write is relevant and continues to provide direct business value as it evolves. Business analyst and customers can help develop these tests and programmers can help maintain these. Easyb is a great tool for creating such automated tests.
