Agile Groovy Acceptance Testing with Geb
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.
Essential Complexity: Developing and maintaining complex software
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.
How to Select and Adopt a Technology
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.
Requirements and Estimating - state of the art
A chance for experience agile developers to learn and share state of the art tips for improving requirements gathering and project estimation.
Prerequisite: Experience working on agile projects
Tim Berglund - GitHubber
Cassandra: Radical NoSQL Scalability
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.
Complexity Theory and Software Development
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.
Decision Making in Software Teams
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.
Gaelyk: Lightweight Groovy on the Google App Engine
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.
NoSQL Smackdown!
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.
Programming HTML5
HTML5 wants to make some major changes to the way we deliver media over the web and the way we mark up our pages, but it also gives us a bunch of new stuff in the browser's programming model. To ignore these new JavaScript APIs is to give up on a richer browser UI and a lot of fun.
Jeff Scott Brown - Core Member of the Grails Development Team
A Thorough Introduction To Grails
Grails represents technology that offers great flexibility and power without the complexity introduced by other Java web application frameworks. Custom tag libraries are a snap. GSP Templates provide a simple mechanism for reusing UI elements. Sitemesh is integrated to help provide a consistent presentation across the entire application. GORM is super powerful ORM. Grails provides simple mechanisms for leveraging the power of Ajax.
James Carr - Software Craftsman
Behavior Driven Development with Client Side Javascript
Back in 2004 there wasn't much in the world of test driven development for javascript... you just had jsunit. Since then there has been an explosion of frameworks for javascript and it is almost to the point where it is difficult to choose the right one.
Jeremy Deane - Chief Architect - Software Engineering Aficionado
Implementing RESTful Web Services
RESTful web services have become the preferred approach to synchronously integrating heterogeneous systems. The architectural style’s success is due in large part to its simplicity. Furthermore, REST is based on a small set of widely accepted standards, such as HTTP and XML and requires far fewer development steps, toolkits and execution engines than conventional SOAP web services.
Resource-Oriented Concurrent Processing
Traditional concurrent development on the Java Platform requires in depth knowledge of threads, locks, and queues (oh, my!). Fortunately, new functional languages that run on the Java Platform, such as Scala, have made concurrent programming easier.
An alternate approach is to implement concurrent processes using a resource oriented computing (ROC) platform. At the heart of this ROC platform is a microkernel that allows processing to scale linearly as more CPUs are added. Consequently, developers are freed from the complexity of Java concurrency and functional programming.
Resource-Oriented Enterprise Service Bus
An Enterprise Service Bus (ESB) provides a platform for service provisioning. The core capabilities that enable provisioning across an enterprise include addressing, routing and transformations. Addressing is the ability to specify the location of a service regardless of transport. Service routing defines a message path across a number of servers or nodes and message content transformations are implemented using XML technologies such as XSLT and proprietary adapters.
Resource Oriented Architecture (ROA) goes beyond RESTful web services and provides a more extensible transport-independent foundation. Furthermore, ROA pushes the integration functionality to the edge of the network (as a URI), translating into better service management and scalability.
Dave Klein - Author of 'Grails: A Quick-Start Guide'
Grails Takes Care of the REST
Representational State Transfer (REST) is fast becoming recognized as the preferred web services architecture in many situations. REST provides a loosely coupled way for applications to communicate with each other across the web. The simplicity and expressiveness of REST make it a perfect fit for Grails. Grails provides a full stack framework with which to build RESTful applications, complete with persistence, a transactional service layer, logging, security services, and more. Whether you're building applications for a service oriented architecture or just want to add some integration points to your standard web apps, you can relax and let Grails take care of the REST.
Groovy Hands On Workshop
You've no doubt heard about Groovy before, but if you've never taken a closer look, now is your chance. Groovy is such a natural fit for a Java developer. Just adding a single extra jar to your project can make it so you can't wait to get to work on Monday.
Groovy integrates so well with Java that Dan Woods, of Forbes.com, says that it's a no-brainer for existing Java shops. ( http://bit.ly/hoJ7it ) But don't just take his, or my, word for it; get to know Groovy for yourself. You'll be glad you did.
Matthew McCullough - Head of Training, GitHub
Cascading through Hadoop: A DSL for Simpler MapReduce
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
Cryptography on the JVM: Boot Camp
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.
Git Going with Distributed Version Control
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 Workshop (Bring A Laptop)
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.
Jenkins Continuous Integration in Action
The team dynamics and agile process revolution of the last several years has taught us that continuous integration (CI) is a necessary part of a healthy agile team. Jenkins (formerly Hudson) is the idea and footprint leader in the CI space. A recent survey stated that over 70% of all CI installations have Jenkins in their DNA. What's so awesome about this particular CI tool?
Get on board with a ground-up survey of how to install, apply, upgrade, and leverage the free an open source Jenkins Continuous Integration server for your build, whether it be Ant, Maven, Gradle, JavaScript, Rake, or just shell scripts.
Simpler Cryptography with 3 JVM Libraries
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)
Sonar: Code Quality Metrics Made Easy
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.

Architectural Kata Workshop
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.
Busy Developer's Guide to CouchDB
With the rise of the NoSQL movement, a whole new crop of different ways to store data suddenly became available to the Java developer. Unfortunately,what didn't come with them was an owner's manual. CouchDB, for example, was the first of the NoSQL databases to be named as such, and offers features not found in the traditional RDBMS: A distributed, robust, incremental replication document-oriented database server with bi-directional conflict detection and management, accessible via a RESTful JSON API, stored ad-hoc and schema-free with a flat address space, that is both query-able and index-able, featuring a table oriented reporting engine that uses JavaScript as a query language. (With a list of buzzwords like that, what's not to love?)
Busy Java Developer's Guide to Android: Basics
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.
Busy Java Developer's Guide to Game Design
Creating a good game begins with finding an idea and fleshing it out into something... fun. In this session, we'll explore the art and science of designing games, including a few exercises designed to spark attendees' creativity.
Busy Java Developer's Guide to Games
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.
Busy Java Developer's Guide to Guava
"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.
Busy Java Developer's Guide to Java 7
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.
Pragmatic Architecture
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 Akka
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.

Prerequisite: Easy Mobile Development
Enterprise Integration with Apache Camel and Spring Integration
Enterprise Integration used to be mundane and tedious - developers had to build all the code by hand and testing was difficult. With the rise of popular Enterprise Integration toolkits such as Apache Camel, this is no longer the case. Apache Camel makes it a breeze to do enterprise integration, and in this session, you'll be introduced to both Enterprise Integration basics as well as implementing them with Apache Camel.
From Zero-to-Hero with EHCache
Ehcache is the most popular open source cache framework for the JVM. It is integrated into many open-source packages, such as Grails. First, we'll cover the concept of caching objects and use cases around caching. In this session, we'll get into Ehcache details about architecture, configuration, design, cache types and more. Attendees will learn how to configure Ehcache and we'll discuss the major configuration options. We'll also do some live code demos so attendees can better understand the concepts and features of caching and Ehcache. Of course, we'll also see how it plugs into ORM / JPA tools like Hibernate.
Intro to Clustering with Terracotta
Terracotta is an open-source cluster framework. In this session, attendees will begin by learning about Terracotta architecture and setup. We'll then examine the Terracotta Toolkit in detail with live code examples. Attendees will learn about features in the Terracotta toolkit: barriers, locking, clustered collections, and more. We'll discuss the usage of these features and how to best utilize them across a cluster of JVM's / app servers. We'll also talk about how to setup for high-availability.

BDD with Cucumber Workshop (Bring A Laptop)
Behavior-Driven Development (BDD) employs the approach of specification by example. Cucumber is such an amazing BDD tool because it’s so good at mapping stories and acceptance criteria to automated functional tests. This is a hands-on workshop using Cucumber-JVM that will have you writing and automating acceptance tests on your own laptop by the conclusion of the session.
Introduction to Lean-Agile Software Development
Successful software development is about building the right product at the right time for your customers. This means focusing attention on the right places in the portfolio of projects and products that your company provides, and optimizing the entire value stream from "concept to cash" for your customers and the development teams.
Strategic Design Using DDD
Not every part of a software system will be well-designed. How do you know where to put the time and effort to refine the design, or refactor existing code? Learn how strategic Domain-Driven Design (DDD) patterns can show you how to know which parts of your system matter most to your business and how to focus your team's design efforts most effectively.
Nathaniel Schutta - Author, speaker, software engineer focused on user interface design.
Code Craft
Despite what some developers think, we spend a lot more of our time reading code, code that was often written by someone that isn't around anymore. How do we deal with this common scenario without resorting to burning our predecessor in effigy? Better, how can we write code in such a way that our successors will heap effusive praise upon us at the mere mention of our name? During this talk, we'll read actual code discussing ways it could be improved. As we work through real examples, we'll explore the importance of patterns, principles like SOLID and SLAP and essential practices like unit testing and continuous integration.
Going Mobile with jQuery
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.
HTML 5 Fact and Fiction
For the last few years, the web has been all a-twitter about web 2.0 (and even the occasional reference to web 3.0.) Yes, the days of static web applications are officially over and while libraries like jQuery and Prototype make it easier to build modern applications, ultimately they are papering over issues in the web standards (and the browsers that implement them.) Today we're building to standards that are from the paleolithic era of web design but that's changing - and HTML 5 is a large part of that. In this talk, we'll discus just what HTML 5 is and why it matters. We'll show how you can build to HTML 5 today and which browsers support what. Thankfully, after many years of stagnation, the future of web applications looks bright!
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.
Usability 101
Day in and day out we are subjected to poorly designed applications. From those we experience directly to the time we waste waiting on others who are struggling with systems that seem like they were built to hinder the user. It doesn't have to be like this and many users are waking up and demanding better applications. Are you prepared to deliver? After this workshop, you will be. When you're done, you'll have the tools you need to make sure your application helps your users kick ass!
Ken Sipe - Architect, Web Security Expert
Agile Velocity
The agile development process is all about early and often feedback. One aspect of feedback is how is the team doing... Are we accurate in our estimates? Are we consistent in our velocity? As velocity varies, what is it telling me?
Enter The Gradle
This presentation introduces the audience to the power of Gradle through many real-world examples that are demonstrated live. By the end of the presentation, you'll understand how Gradle helps to elegantly solve the challenges that we face in our daily enterprise builds.
So you want to be an Architect
This session is a quick look at all aspects of being a corporate software architect. Whither you are a developer looking to move into the role of architect, needing to have an understanding of what is expected or already in the role of software architect looking for new and interesting ideas, this session is for you.
Venkat Subramaniam - Founder of Agile Developer, Inc.
Collections for Concurrency
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.
Concurrency without pain in pure Java
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.
Integrating JVM Languages
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: The rise and fall of empires: Lessons for language designers and programmers
Keynote on lessons we can learn from our civilizations and evolution.
State of Scala
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.
Testing with Spock
Spock is an awesome tool that exploits Groovy AST transformation to provide elegant, fluent syntax for writing automated unit tests and functional tests. In this presentation we will learn how to use Spock to unit test both Java and Groovy code.
Mark Volkmann - Software Consultant and Partner at OCI
jQuery - RIA Miracle!
Developing rich internet applications using HTML, CSS and JavaScript is now a common exercise. While it can be done using only those client-side technologies, JavaScript libraries greatly simplify the task. They also shield developers from most browser differences. The jQuery JavaScript library is a very popular option.
