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.

In this workshop we take the unique approach of moving from release back through testing to development practices, analyzing at each stage how to improve collaboration and increase feedback so as to make the delivery process as fast and efficient as possible. At the heart of the workshop is a pattern called the deployment pipeline, which involves the creation of a living system that models your organization's value stream for delivering software. We spend the first half of the workshop introducing this pattern, and discussing how to incrementally automate the build, test and deployment process, culminating in continuous deployment.

In the second half of the workshop, we introduce agile infrastructure, including the use of Puppet to automate the management of testing and production environments. We'll discuss automating data management, including migrations. Development practices that enable incremental development and delivery will be covered at length, including a discussion of why branching is inimical to continuous delivery, and how practices such as branch by abstraction and componentization provide superior alternatives that enable large and distributed teams to deliver incrementally.

Although Agile has proven to provide incredible benefits in software development and delivery, it is not foolproof, nor a “Silver Bullet.” Plenty of factors need to be considered before attempting this highly disciplined approach.

Learn from the mistakes other organizations have made and discover which pitfalls to avoid to ensure that your first attempt at applying an Agile approach will be met with a successful outcome. This hour-long web seminar will explore these areas and provide clear steps your team and organization should consider to provide a clear set of tools to maximize the opportunity for best results possible.

Some come to Agile assuming it involves less discipline than their traditional methods, but this is a misperception. Today, the need for discipline in software development is greater than it ever was. Agile answers that need, arriving at discipline through the Team. Agile Teams must collaborate to develop strong discipline in both planning and execution.

We'll discuss how teams can obtain Agile discipline to achieve one of our core principles of delivering “working software” frequently. We'll explore some of the key Agile planning and engineering practices like continuous planning, Test-Driven Development, Continuous Integration and Acceptance testing. We'll look at the discipline involved in these practices, their inter-relationship, and the benefits they realize in delivering value to the customer.

The Executable Specification is a result of implementing a set of practices that allow frequent change in software products to ensure that the right product is delivered economically. We'll explore how mature Agile Team's go from User Stories to Executable Specifications by implementing practices that foster collaboration, shared understanding and liberal automation to achieve living documentation that supports the team.

We'll collaboratively walk through a evolving example of how software can be created by utilizing an executable specification to document the the software requirements and confirm it completeness.

There is a good amount of excitement about the new version of Java. The big
evolution of course is the lambda expressions. In this presentation we will dive into the language features in Java 8, take a look at some of their nuances, and look at ways to put them to good use.

Java 8 language capabilities and application.

Relational databases have ruled the world since the dawn of time (or so it appears). They power our enterprises and for many in the corporate world, it may be hard to imagine life without them. Each decade a novel idea would challenge the status quo and make a case to deviate for the tradition. A flock of enthusiastic programmers, like your humble speaker back in the early 90s, would throw their support around it, only to be crushed eventually by the large vendors and enterprise standards. But, the excitement around NoSQL has shown that enterprise data is not the only thing that's persistent.

In this presentation we'll learn how NoSQL deviates from those deep rooted traditional approaches, and how this may be useful. We will also discuss the situations where these types of databases may be more appropriate.

JavaScript has a mixed heritage: OO and Functional. To date, us developers have focused on the OO side of JavaScript and not much mind-share has been given to the other, more powerful side. In this session we'll explore how to use the power of functional Javascript.

JavaScript has elements of two distinct programming languages: Self and Scheme. These two languages are very different - and some of JavaScript's weirdness is due to this mixing of very different language designs. The conceptual models are also very different between Self and Scheme - one is a prototypical object based language, while the other is a functional language. In this session, we'll discuss the elements of how the Scheme functional programming language manifest in JavaScript. We're going to explore how you can write JavaScript in a more elegant and powerful way by applying functional concepts.

So you think you've picked up enough JavaScript to be dangerous, but feel like the whole prototypical language thing is still a mystery. In this session, we'll go from basic JavaScript to advanced JavaScript. We'll discuss and code modular JavaScript with CommonJS. We'll look into the details of a prototype language and discuss things like parasitic inheritance. We'll also look at JavaScript libraries that will help you get the most out of JavaScript - not jQuery, but a library like UnderscoreJS and SugarJS.

This is a fast paced session meant to bring you up to speed with the latest and greatest JavaScript techniques and tools. Whether you're building client side JavaScript with HTML5 or Appcelerator Titanium, or server-side JavaScript with node.js, you'll come away with knowledge and patterns for how the pro's use JavaScript for building real apps.

We've come a long way down the JavaScript road. Gone are the days of 'just hack it' for the web - architecting even a small project in JavaScript can be a challenge. Thankfully, there are several frameworks to help you; the most popular currently is Backbone.js.

Before you start using a framework in JavaScript, you will want to understand the techniques expert JavaScript programmers use to build them. In this session, we'll dive into design patterns in JavaScript, and do live coding so you can see these patterns applied. Even if you're not using a framework, you can use these design patterns to make your code more maintainabile, elegant, and concise.

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.

This session describes the current thinking about emergent design, discovering design in code. The hazard of Big Design Up Front in software is that you don't yet know what you don't know, and design decisions made too early are just speculations without facts. Emergent design techniques allow you to wait until the last responsible moment to make design decisions. This talk covers four areas: emergent design enablers, battling things that make emergent design hard, finding idiomatic patterns, and how to leverage the patterns you find. It includes both proactive (test-driven development) and reactive (refactoring, metrics, visualizations, tests) approaches to discovering design, and discusses the use of custom attributes, DSLs, and other techniques for utilizing them. The goal of this talk is to provide nomenclature, strategies, and techniques for allowing design to emerge from projects as they proceed, keeping you code in sync with the problem domain. This talk shows lots of examples of how to make this concept work in your environment.

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.

This talk defines of DSLs (Domain Specific Languages), distinguishes the types of DSLS (internal and external), and shows examples of building DSLs of several kinds. It shows how to utilize DSLs for externalizing configuration (which you're already doing, whether you realize it or not), how to make your code readable to humans, how DSLs make developer tools better (and how to use DSL techniques to build your own tools), and how DSLs can provide your users unprecedented flexibility and power, by building DSLs customized to their job. This talk provides a good foundation for the subject if you've never seen anything about it, but keeps the focus on practical goals.

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

Learning the syntax of a new language is easy, but learning
to think under a different paradigm is hard. This session
helps you transition from a Java writing imperative programmer to a
functional programmer, using Java, Clojure and Scala for
examples. This session takes common
topics from imperative languages and looks at alternative ways of
solving those problems in functional languages. As a Java developer, you know how to achieve code-reuse
via mechanisms like inheritance and polymorphism. Code reuse is
possible in functional languages as well, using high-order
functions, composition, and multi-methods. I show examples from my book Functional Thinking of shifting your perspective on problems, ceding messy details to the language, working smarter, not harder, and how to deal with multiparadigm languages.

The basics of developing for the Android platform will be explored, from setting up the SDK to using the Android Studio IDE and the generated Gradle build files. No previous experience is required, other than a basic knowledge of Java.

After discussing how Android fits into the marketplace, we'll look at creating applications, how to use activities, and working with layouts.

Building on the the previous talk, we'll add intents, customized layouts for alternative configurations, talk about the activity lifecycle, use logging, and more.

We'll deploy to both emulators and connected devices, and change input styles.

Testing is well-established in the server-side Java ecosystem but is often an afterthought when it comes to Android development. This talk will review the available options and libraries used to do both unit and integration testing.

We'll look at tools that come with the SDK, as well as third-party tools for UI testing.

Groovy isn't designed to replace Java – it just makes Java cleaner and easier to develop. This presentation will look at various tasks Java developers need to do and demonstrate ways Groovy can help.

Topics will include building and testing applications, accessing both relational and NoSQL databases, working with web services, and more.

The Gradle build tool is one of the most successful projects in the Groovy ecosystem because it addresses a difficult problem – every major build is a custom build. Gradle builds are written in Groovy, so the full power of the language is available if you need it. Gradle supports Maven project structure and repositories and uses Ivy dependency management without being bound by their normal constraints. With major systems like Grails, Hibernate, and the Spring Framework moving to Gradle, this is a technology worth taking the time to understand.

This talk will cover the basics of Gradle both through simple examples and by examining the build files for major open source projects.

Statistics is hot lately, due in part to the easy availability of large data sets and the successes of people like Nate Silver. These aren't your father's statistics, however. A quiet revolution has swept through the field, shifting it from traditional frequentist methods toward a more Bayesian approach. This talk will discuss Bayes' Theorem and show you how to do simple, back-of-the-envelope calculations to apply it to a wide variety of problems.

In addition, we'll also talk about common errors non-experts make when dealing with statistical conclusions, ranging from small sample size issues to the use of arbitrary endpoints to the problem of overfitting and more.

Ever wish you could use your JavaScript-foo to build a NATIVE mobile app? Wish there was an open-source platform that would let you build awesome cross-platform mobile apps? Come to this session and learn about Titanium, an open-source, JavaScript based platform for creating native mobile apps.

Titanium is an open-source development tool for producing cross-platform mobile applications by Appcelerator. Using Titanium, you develop your mobile application using Javascript coded against the Titanium API's. The Titanium platform invokes their builder to take your Javascript and build a native application for iOS and Android.

This session will walk you through the details of building great apps for the Android and iOS platforms. We'll talk about Titanium development, its ecosystem, and architecture. We'll spend time looking at lots of code - we'll build an app, in fact, while we discuss and explore the framework. We'll also spend some time discussing best practices, what to expect when developing against it, and the limits of this type of development.

The Single Page App, or SPA, require the developer thinks about architecture in new ways compared to traditional server-side page generation web apps. Whether you've used Java web frameworks like Spring Web, or Struts, dynamic frameworks like Grails or Rails, or even Django or PHP, you will need to learn some new techniques for building SPA type applications. We discuss the architecture and design of Service Oriented Front End Architectures (SOFEA) in this session.

In this session, we'll look at structuring your app from both the client and server side. Using a SPA framework like Backbone.js or Ember can help, but does not answer critical design questions. This is a fast paced session where we'll talk about SPAs, REST, SEO, and much more.

Have you looked into Scala? Scala is a new object-functional JVM language. It is statically typed and type inferred. It is multi-paradigm and supports both object oriented and functional programming. And it happens to be my favorite programming language.

If you are interested in Scala, how you are planning to learn Scala? You probably are going to pick up a book or two and follow through some examples. And hopefully some point down the line you will learn the language, its syntax and if you get excited enough maybe build large applications using it. But what if I tell you that there is a better path to enlightenment in order to learn Scala?

Scala Koans, a set of test cases that will teach you Scala language. The Scala koans will help the audience learn the language, syntax and the structure of the language through test cases. It will also teach the functional programming and object oriented features of the language. Since learning is guided by failing tests it allows developers to think and play with the language while they are learning.

Workshop Requirements

Namaste,

For those planning to attend the Scala Koans…

Welcome to Scala Koans!

Scala Koans is an interactive session that puts the programming and learning in your hands. Therefore, a laptop is required by all participants. If you do not have a laptop, then perhaps you have a friend with a laptop, is so, well, that would work too. In order to participate in the Scala Koan endeavor, a few things are required:

• A laptop
• A modern JDK installation. JDK 1.6+ will suffice. Remember that it should be a JDK and not a JRE!
• Your JDK should be mapped properly to JAVA_HOME and your PATH variables.
• An installation of your favorite IDE or editor.
• An inquisitive mind.

The process of actually running the koans will be covered during the session. Unfortunately, Internet connectivity is sometimes a dicey affair and at times it can rain on our parade. To avoid having to wait for the install at the conference you can prepare for the koans before the conference! If you don't have the opportunity to do this, we will have either memory sticks or private networks at the conference.

If you want to get started with the set up:

1. Download the koans by visiting https://bitbucket.org/dmarsh/scalakoansexercises and click on the download link on the right hand side of the page. (or you can clone the bitbucket project)
2. Unzip the koans: dmarsh-scalakoansexercises-#####.zip
3. cd into the dmarsh-scalakoansexercises-#### folder
4. If you are in Linux or MacOSX run: ./koans, on Windows ./koans.bat
5. After some initialization, you are now in the koans/sbt shell (you should see a > prompt)
6. In the shell run the following commands:
   a. test:compile
   b. eclipse (if you are planning to use Eclipse)
   c. gen-idea (if you are planning to IntelliJ Idea)
7. Exit the shell by typing exit

Before attending the koans session, you may want to take the opportunity to load some Scala Plugins onto your favorite IDE and Editor. Below is a list of resources that you can use to enhance your environment so that you can enjoy Scala syntax highlighting and other helpful tools like refactoring, debugging and analysis.

Eclipse - The Eclipse has an IDE plugin for Scala called aptly scala-ide. All the information about the plugin can be found at http://scala-ide.org including an easy to follow along video located at http://scala-ide.org/docs/current-user-doc/gettingstarted/index.html

IntelliJ - IntelliJ has a Scala plugin that can be found by going to Settings -> Plugins, clicking on 'Browse Repositories' button and searching for the 'Scala' plugin on the left. Right click on the 'Scala' and choose 'Install'. IntelliJ will prompt you to restart the IDE, do so, and enjoy.

NetBeans - Currently, Github user 'dcaoyuan' hosts a NetBeans Scala plugin at the address: https://github.com/dcaoyuan/nbscala. I have not tried this out since the number of NetBeans users has shrunk in recent years. If you are an avid NetBeans user, and wish to try it, you can let me know the results during the session. There is additional information at: http://wiki.netbeans.org/Scala

Emacs - Github user 'aemoncannon' has created 'ENSIME' (ENhanced Scala Interaction Mode for Emacs) at the address and has a great following. https://github.com/aemoncannon/ensime with some documentation at http://aemoncannon.github.io/ensime.

VIM - For VIM users you can use https://github.com/derekwyatt/vim-scala as a VIM plugin that offers Scala color highlighting

That is it. Hope to see you soon.

Invoke dynamic is a Java 7 feature that had the most impact at the bytecode level and also in terms of performance. First perceived as a feature to help dynamically typed languages on the JVM, it turned into a powerful feature that has been exploited quite a bit in the implementation of features in the Java
language itself.

In this presentation we will understand what problem this features really solves and how it has influenced other features in the Java language and on the Java platform.

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?

In this session, we'll explore several ways that Spring has changed over the years and look at the best approaches when working with the latest versions of Spring.

In this presentation, we'll see how to use Spring to create, secure, streamline, hyperlink, and consume REST APIs.

In modern applications, there are a diverse array of clients consuming content from the web. Each of these clients has unique capabilities and limitations, therefore demanding presentation of the application to be tailored to each device. As a result, presentation logic is often pushed into the client itself, leaving the application to serve a common data-oriented lightweight API to be consumed by each client.

In this session, we're going to combine the magic of Spring Boot and the magic of Spring Data to yield something even more powerful. You'll see how to quickly build an application's persistence layer, whether it stores data in a RDBMS, Mongo, Neo4j, or several other popular data stores. You'll also see how to create a functioning REST API with nothing more than an interface and a domain type.

Spring Boot dramatically simplifies application development with Spring. But before Spring Boot came along, Spring Data was already making developers' lives easy when it comes to working with data. When combined, Spring Data and Spring Boot can make data persistence the easiest part of your application.

Today’s interconnected world requires that organizations rapidly deliver flexible-integrated solutions. The conventional approach is to integrate heterogeneous applications using web services but unfortunately that tends to tightly couple those applications. In this session we will explore several alternatives for achieving Enterprise Integration Agility.

Public Web APIs are increasing at an exponential rate resulting in an ever more connected web. This connected contagion is not just relegated to the domain of Web 2.0 but has infected the corporate world. In fact, companies are becoming more reliant on Software as a Service (SAAS) to provide key business functions.

Combating this contagion requires an approach that provides a type of insurance against constant change and lays the foundation for evergreen enterprise solutions. In this session we will explore three popular architectural styles including Message Oriented, Service Oriented, and Resource Oriented Architecture that are used to achieve Enterprise Integration Agility. In addition, I will provide examples of each architectural style using ActiveMQ/Camel, Mule ESB, and NetKernel.

In this session, I will demonstrate several concurrent processing techniques including Fire and Forget, Fork-Join, Producer-Consumer, and Asynchronous Web Services using the Java Concurrency Library, the Akka Framework and the Spring Framework.

Traditional concurrent development on the Java Platform requires in depth knowledge of threads, locks, and queues. Fortunately, new languages and frameworks that run on the Java Platform have made concurrent processing easier. This session apply concurrent processing patterns and techniques using several popular libraries and frameworks.

Simulation allows a rigorous, scalable, and reproducible approach to testing. The separation of concerns, and the use of a versioned, time-aware database, give simulation great power. This talk will introduce simulation testing, walking through a complete example using Simulant, an open-source simulation library.

Simulation allows a rigorous, scalable, and reproducible approach to testing:

Statistical modeling

Simulation begins with statistical models of the use of your system. This model includes facts such as “we have identified four customer profiles, each with different browsing and purchasing patterns” or “the analytics query for the management report must run every Wednesday afternoon.” Models are versioned and kept in a database.

Activity streams

The statistical models are used to create activity streams. Each agent in the system represents a human user or external process interacting with the system, and has its own timestamped stream of interactions. With a large number of agents, simulations can produce the highly concurrent activity expected in a large production system.

Distributed execution

Agents are scaled across as many machines as are necessary to both handle the simulation load, and give access to the system under test. The simulator coordinates time, playing through the activity streams for all the agents.

Result Capture

Every step of the simulation process, including modeling, activity stream generation, execution, and the code itself, is captured and stored in a database for further analysis. You will typically also capture whatever logs and metrics your system produces.

Validation

Since all phases of a simulation are kept in a database, validation can be performed at any time. This differs markedly from many approaches to testing, which require in-the-moment validation against the live system.

Separation of concerns

The separation of concerns above, and the use of a versioned, time-aware database, gives simulation great power. Imagine that you get a bug report from the field, and you realize that the bug corresponds to a corner case that you failed to consider. With a simulation-based approach, you can write a new validation for the corner case, and run that validation against your past simulation results, without ever running your actual system.

This talk will introduce simulation testing, walking through a complete example using Simulant, an open-source simulation library.

This is a revised and updated version of the previous talk, with current thinking from practice and the literature. The talk presents why conflicts with your manager are inevitable based on differences in priorities and perspectives, and how to plan for them. The goal is to show you how to build the loyalty relationship that allows you to get what you need when you need it.

Topics covered will include diagnosing communication styles, lessons from game theory, working within the organizational hierarchy, and lessons on how to build a relationship with your manager that still allows you the freedom to express yourself and what you really want.

This is the first in a new series on resource-oriented systems. The goal of the series is to provide practical guidance on the design and implementation of next generation systems that are flexible, extensible, high-performance and future-friendly. The talks are designed to work as arc, building upon each other, but they should also stand alone. The first topic is a guided walk through of building quality REST APIs.

We will focus on the architecture of the Web and how it can help us model and manipulate our important business concepts. We will discuss the role of stable identifiers, intentional representation design, hypermedia affordances and architectural consistency. The goal is not to be “RESTful”, the goal is to build systems that display the properties we require.

This talk will be accessible for people new to REST, but also different enough that those who have attended previous REST talks will learn new things.

This is the second in a new series on resource-oriented systems. The goal of the series is to provide practical guidance on the design and implementation of next generation systems that are flexible, extensible, high-performance and future-friendly. The talks are designed to work as arc, building upon each other, but they should also stand alone. This second talk is an introduction to the use of Semantic Web technologies to enable collaboration without coordination.

REST is a means to an end, but it is not a satisfactory end state. It usually pushes complexity to the client in ways that make data integration difficult across multiple sources. The W3C Semantic Web initiative introduces us to new technologies for linking resources and querying across them in powerful new ways. We will learn about the RDF model, what it brings to the table and how we can use it connect information regardless of where and how it is stored. We will use the SPARQL protocol and query language to ask powerful questions of arbitrary resources. We will also see how we can create new information just by asking for it.

This is the third in a new series on resource-oriented systems. The goal of the series is to provide practical guidance on the design and implementation of next generation systems that are flexible, extensible, high-performance and future-friendly. The talks are designed to work as arc, building upon each other, but they should also stand alone. This third talk will introduce you to RDFa, one of the most exciting technologies estimated to be used on at least 25% of the indexed Web.

We understand that documents contain information, but it is usually only accessible to humans if they know where and how to find them. What if we could automatically extract arbitrary information about arbitrary domains and connect it to information held elsewhere? What if we could use the information in a document to help us organize our content better? What if this embedded information could help external search engines index the public Web better and improve your rankings?

This talk will show you how to weave and extract information in HTML, XHTML and arbitrary XML using standard tools such as RDFa. In the process, you will learn how to free the information so that it may be reused in powerful and unanticipated ways.

If you're not terrified, you're not paying attention.

Publishing information as webs of data does not require us to just give it away. We have a series of tools and techniques for managing identity, authentication, authorization and encryption so we only share content with those we trust.

Before we tackle Web Security, however, we need to figure out what we mean by Security. We will pull from the worlds of Security Engineering and Software Security to lay the foundation for technical approaches to protecting our web resources.

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 workshop 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.

We'll look at some popular web sites discussing what we would do differently in a mobile context and then take a look at the actual mobile experience to see what other designers actually did. Using paper, we'll work though a design or two of our own. We'll wrap up discussing various methods of creating a mobile app - should we use the web or build something native? What about shell apps? While we might not have all the answers, at the end of this workshop you'll know what questions to ask when thinking through your own situation.

Workshop Requirements

This workshop is more analog than digital - a laptop is not required. A pen or pencil though, is!

You may have noticed today's web applications involve more than a few lines of JavaScript. You've probably also figured out JavaScript lacks certain…features…that make writing non-trivial applications more challenging. How do we resolve this conundrum? Luckily for us, we can leverage libraries like Backbone add some structure to our code. Backbone brings the concepts of the model view controller pattern we've applied to the server for years to the browser.

In this workshop, we'll introduce the idea of asynchronous user interfaces and show how Backbone helps us write that style of application. We'll work our way up from the bottom building a simple application along the way. We'll create models, we'll use a templating library (or two) and we'll also explore Underscore - a JavaScript utility belt you can use right now today without committing to building MVC style web applications.

If you're struggling to manage an increasing amount of JavaScript or you want to build more responsive web applications, this workshop can help!

Workshop Requirements

For this workshop you should have:

• Laptop
• Text editor or IDE
• One or more “modern” (Chrome, Safari, etc) browser

Optionally, you can have Git installed but it isn't required. Before the workshop, take a minute to setup the code somewhere on your laptop. The code is on github:

https://github.com/ntschutta/backbone_workshop

You can clone the repo from there or simply download a zip if you prefer. That's it! See you in Florida!

In this session you will learn to strategically introduce technology innovations by applying specific change patterns to groups of individuals. Using these patterns and related techniques will not only benefit your organization but will ultimately benefit your career as a technologist by making you a better influencer, writer, and speaker.

The rapid pace of technological innovation has enabled many organizations to dramatically increase productivity while at the same time decrease their overall headcount. However, the vacillating global economy combined with “change fatigue” within organizations has resulted in a risk averse culture. In such an environment how can one possibly introduce and inculcate the latest technology or process within an organization? The answer is to have a solid understanding of Diffusion Theory and to leverage Patterns of Change.

Find yourself overwhelmed with hundreds of to-dos? Is your hard-drive littered with dozens of killer ideas that you started with enthusiasm and then just fizzled away? Do you feel like you are moving as fast as can but only getting to the wrong place quicker? Well perhaps this session will help.

There are various techniques and strategies available to us today that aim to help with exactly this conundrum - from Getting Things Done ™ to Personal Kanban. Unfortunately it is often easy to be extremely productive using these systems, but not very effective. After all, it's not about getting things done, but getting the RIGHT things done. In this talk we will discuss not only how to get things done, but also attempt to figure out what it is you actually need to be doing.

In this session, I will attempt to show you how you can leverage various strategies to be more effective, knock to-dos out and have fun while doing it. If time permits we will close with an overview of the tools that are available to you, and how you can use these to become a to-do list ninja :)

In this session we will look to see how we can refactor our learning - what tools, and methodologies can we use to help us learn quicker and better - how we can create a store that gives us quick access to information when we really need it.

We all work in an industry in which not only do the tools that we use change ever few years, but one in which we have to shift the very paradigms these tools are built on! Even the most trivial of projects entails tens of different toolkits, frameworks, and languages coming together, and somehow we need to know how to leverage each one. How does one keep up? Despite all our years in schools, and our in-born nature to learn, we often are never taught how to learn. How can we learn faster, and retain even more?

In this session we will take a look at various tools and techniques available to us and see how we can make our learning effective.

In this session, we will take a look at Angular - a new MVC framework by Google. We will discuss some of the terminology that Angular offers, and see how we can use that to develop highly interactive, dynamic web applications. See “Detail” for a list of topics I cover and the Github repo URL

This is an intro-level talk we will take a look at Angular and developing rich web applications. Angular embraces HTML and CSS, allowing you to extend HTML towards your application, and uses plain JavaScript which makes your code easy to reuse, and test.

Note: This is an intro level talk. It is targeted towards developers who are curious about Angular and want to learn about the fundamental features and concepts in Angular.

Topics Covered -

• Bootstrapping an AngularJS application using ng-app
• ng-init and the evaluation {{ }} directive
• A brief look at $rootScope
• ng-model
• Controllers, Dependency Injection, and the View-Model ($scope)
• Looping using ng-repeat
• Forms using ng-form, form validation and submission in AngularJS
• Angular provided filters
• Making AJAX requests using $http

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.

In this session, we will focus on the enterprise - where the user-base is known and fairly consistent, but typically where user interface and interaction are not the top most priorities. We will discuss some rules for good design, look at a few simple design elements that can make your web apps shine, and your users rejoice.

Traditional automated testing approches combine input generation, execution, output capture, and validation inside the bodies of single functions. Generative testing approaches gain expressive power by isolating these steps.

With generative testing:

• a generator is a declarative description of possible inputs to a function
• execution is up to your program
• outputs are data, and can be captured for future study
• validators are programs that have access to the generators, the program, and the outputs

There are a number of benefits to this approach:

• once test data generation is separate, it is immediately obvious that such data generation should be statistical, not merely a few hand-picked cases
• validators can be reused in a variety of
• it becomes easier to identify and develop declarative, logic-based validations, rather than imperative ones
• the various phases can be decoupled and run at different times

This talk introduces test data generation and generative testing, using for its examples the data.generators and test.generative libraries developed by the author.

• test.generative
• data.generators
• chapter 10 of Programming Clojure

Logic programming delivers great expressive power: you work in domain abstractions, and your program figures out execution details. And it has never been easier. With the Datalog engine in Datomic Free, you can work both with databases and with your own data in plain Java collections.

Datalog queries have the expressive power of SQL + recursion, so is a good fit for systems that want “the power of SQL” but e.g. more flexibility. When combined with a universal schema, Datalog is particularly easy to learn and to read.

Datomic's datalog implementation works with immutable database values, providing additional benefits:

• decompose a query into multiple steps without compromising performance or correctness
• perform logic and navigation as separate steps, using the entity API
• join across 2 or more databases
• query past values of the database
• perform cross-temporal queries of different versions of your data

In this talk you will learn

• the basics of writing datalog programs
• the difference between datalog and prolog
• how to create reusable abstractions with datalog rules
• how to extend datalog with your own functions and predicates
• querying databases
• joining across multiple databases
• using datalog with your own data
• decomposing queries into logic and navigation
• time travel

On the Web

• A short video introducing datalog
• Reference documentation for Datomic query
• The Day of Datomic examples repository

edn and Fressian are self-describing, schema-free, batteries-included, extensible data languages. In this talk, you will find out where you might benefit from these languages over e.g. JSON or XML.

Systems use many languages, and not just programming languages such as Java, C#, Ruby, or Python. Systems also relay on data languages, both for data on the wire, and for data at rest. These data languages differ greatly in their design objectives and capabilities, and are often less understood than their programming language counterparts.

This talk will introduce two data notations: edn and Fressian, which share several common characteristics. Both are

• self-describing
• schema-free
• batteries-included
• extensible

These capabilities align well with the dynamic, flexible needs of real systems. And in their key difference (text vs. binary), edn and Fressian cover the bases of human readability and maximum performance.

The enterprise today consists of tens, if not hundreds of applications, all designed to meet the needs of the business. These applications rarely live in a silo, and often there is a need to establish a communication protocol between these applications.

There are various approaches to integration, and in this talk we will discuss the pros and cons of each. We will then focus on one particular approach, and solution - Spring Integration brought to us by the folks at Spring Source. We will talk about both inter and intra application integration, and look at some of the ways we can leverage Spring Integration within the enterprise

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.

In this presentation, we'll look at several examples of Spock tests and review most of its capabilities, including mock objects and integration with Spring.

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. This talk discusses using the radar for personal breadth development, architectural guidance, and governance.

ThoughtWorks Technical Advisory Board creates a “technology radar” twice a year, a working document that helps the company make decisions about interesting technologies and where we spend our time. ThoughtWorks then started conducting radar-building exercises for our clients, which provides a great medium for technologists company-wide to express their opinions about the technologies they use every day. For companies, creating a radar helps you document your technology decisions in a standard format, evaluate technology decisions in an actionable way, and create cross-silo discussions about suitable technology choices. This session describes the radar visualization and how to conduct a radar building session for yourself. After a brief introduction, the bulk of the workshop consists of attendees building a radar for the group, following the same procedure you'll use when you do this exercise at your company. At the end, we'll have created a unique Radar for this event and practiced doing it for yourself.

Git, at it's core, leverages a relatively simple data structure to maintain history. In this session we will take a look at this data-structure, which in turn will give us a better view of how Git manages history, and how better to work with it. NOTE: This is NOT an introduction to Git. This session assumes familiarity with Git concepts such as init, add, commit and merge.

Git has fast emerged as one of the leaders in DVCS. Git may seem arcane, but under the covers, leverages a very simple data-structure to store your version history. As developers, it has always serves us well to know how things fundamentally work, and Git is no different. In this talk we will explore this data-structure, and how the various commands you invoke against Git mutate it.

In this session, I'll show you how to secure your Spring application with Spring Security 3.2. You'll see how 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.

Although we may invite guests into our homes and give someone a ride in our car, we locks and alarms on our homes and our cars to keep uninvited and malicious visitors out. Similarly, we allow people to use the applications that we develop, but we probably want to control the access that they have.

Security is an important aspect of any application. And while we could program security rules into the web controllers and methods in our application, we'd find ourselves cluttering our business logic with repetitive security code. Security is a cross-cutting concern–begging to be handled with aspect-oriented techniques.

Spring Security is an authentication and access-control framework based on Spring that provides security aspects. With Spring Security, you can declare who is allowed to access your application and what they're allowed to see, keeping your application logic focused and uncluttered with security details.

Languages offer a lot more than syntax and compilers. They often have supporting libraries and special facilities that set them apart from other languages. Some languages offer special compiler support for a particular construct, like tail call optimization, for example. Others provide interesting library support or capabilities.

In this presentation we will dive into 12 cool things we can do with different languages on the JVM, things that are either impossible or hard to do in Java, but are quite easy and useful to realize in other popular languages on the JVM. If mixing these languages is an option on your projects, you'll have dozen more reasons after this presentation.

No business objectives will be accomplished during this talk.

The purpose of “Pure Fun” is to participate in the sheer joy of using computers. Each talk is an individual performance where you might see or participate in some of the following:

• Exploring music with SuperCollider and Overtone
• Flying an A/R drone helicopter
• Controlling a robot
• Developing a core wars game
• Visualizing data from ridiculous sources

Groovy has a very easy learning curve for Java developers, so many people become Groovy users without realizing all it can do. This presentation will examine features of Groovy that can make your life easier once you're past the initial adoption stage.

Examples will include closure coercion, mixins, simple runtime metaprogramming, operator overloading, drop and take, a tour through some of the overlooked methods in the Groovy JDK, and more.
