Java EE 7 is around the corner and the horizons for Java EE 8 are emerging. This session looks into the key changes the community can expect. The goal of this session is to foster interest and discussion around these changes.

Some of the changes discussed include retiring EJB 2 entity beans and JAX-RPC, greater alignment with CDI, WebSocket/HTML 5 support, a standard API for JSON processing, the next version of JAX-RS, an overhaul of JMS, long-awaited concurrency utilities, batch processing in Java EE and much, much more.

Domain-Driven Design (DDD) promises to simplify enterprise application development and is gradually gaining traction as an alternative to traditional four-tier architectures originally popularized by J2EE. As the name implies, DDD is an architectural approach that strongly focuses on materializing the business domain in software. This session demonstrates first-hand how DDD can be implemented using Java EE via a project named Cargo Tracker.

Part of the Java EE Blue Prints, Cargo Tracker seamlessly maps concepts like bounded contexts, layered architectures, entities, value objects, aggregates, services, repositories and factories to realistic code examples. The Cargo Tracker project also embraces popular practices adopted by the DDD community such as Object Oriented Analysis, Domain Models, Test Driven Development, Agile Refactoring, Continuous Integration, Object Relational Mapping, Dependency Injection and Cross-Cutting Concerns, incorporating these concepts into a realistic Java EE application.

JMS is the Java standard for accessing enterprise messaging systems. This session introduces JMS 2 (JSR 343), the first update in more than a decade and easily the longest-awaited component of the forthcoming Java EE 7 standard.

The biggest new feature of JMS 2 is a new API that makes JMS much easier to use, especially in a Java EE application. JMS 2 also provides API features to support greater scalability as well as additional messaging features and a long list of minor enhancements and clarifications. With JMS 2 final with Java EE 7, now is an ideal time to find out more about it.

In this session, we will also discuss what might be next for the JMS specification.

Many of you may have an architect title, take on the role of an architect, or even aspire to be an architect, but are you thinking like an architect? Architectural thinking is learning to look at a problem or task from an architect's point of view. In this session we will look at many facets of architectural thinking, including how requirements shape the architecture, component-based thinking, how to make architecture decisions, and what feasibility and vitality means to an architect.

Agenda:

• expectations of an architect
• technical breadth vs. depth
• how requirements shape the architecture
• making architecture decisions
• component-based thinking

Just as developers use design patterns in software development, architects use well-defined architecture patterns to get a head start on defining the characteristics and shape of the architecture for a system. In this session we will explore some of the more common architecture patterns and use concrete real-world examples to demonstrate how the patterns work. I will also go over the pros and cons of each pattern and discuss how requirements and operational aspects can drive which patterns to use. Using the right architecture pattern for your system is critical, because as we all know, once in place the architecture is very hard to change.

Agenda:

• Why use architecture patterns?
• Layered Architecture Patten
• Event Driven Architecture Pattern
• Microkernel Architecture Pattern
• Space-based Architecture Pattern

In the past I have presented quite a few fun sessions about software development anti-patterns - things we repeatedly do while developing code that produce negative results. In this session, I will use the same “pattern” as with my other anti-pattern talks and introduce and discuss many of the common software architecture anti-patterns. These are perhaps more significant than the development anti-patterns because they are harder to refactor. Therefore, knowing these anti-patterns ahead of time will save you time, trouble, and perhaps even your job!

Agenda:

• Introduction
• A detailed look of the most common architecture anti-patterns

Back in the day, web developers had to rely on their wits and a plethora of alert statements - to say our toolkit was spartan would be an understatement. But with the increased importance of web front ends and the rise of JavaScript MVC frameworks, a modern web developer toolkit is finally emerging.

We've evolved from text editors to full fledged IDE's with code completion and refactoring tools but our toolchain doesn't end there. With multiple testing libraries, mocking frameworks, test drivers and even code coverage tools, today's web developer gets to walk downhill on a sunny day.

Many software developers point their career towards ascending to the gilded rank of Architect…but what does it mean to actually be one? While many of us labor under false pretense of abject technical decision making, the reality is often very different. You'll code less, spending more time on activities that lack an objective green/red bar. But you'll also an opportunity to impact far more than one project.

In this talk, I'll speak to my own journey. We'll touch on influencing coworkers, the importance of communication and the importance of cup of coffee.

By now, the importance of having a mobile solution is obvious to just about every seat in the organization…but how do develop expertise? How do we work through the inevitable politics and organizational issues? What about the technical questions about hybrid vs. web vs. native?

Before you think about a mid life career change, spend some time listening to what we did in one large company. We may not have had all the right answers, but we learned a few things along the way.

Architecting and developing user interfaces used to be relatively easy, pick a server side framework, define a standard monitor resolution and spend your days dealing with browser quirks. But today, the landscape presents us with a plethora of screen sizes and resolutions covering everything from a phone to a tablet to a TV. How does a team embrace this brave new world knowing that the future will introduce even more volatility to the client space?

This talk will walk you through this brave new world. We'll discuss the deluge of devices the typical application must deal with today as well as looking at the plethora of client side rendering technologies. This isn't strictly a front end problem though, we need to reconsider how we've built our server side solutions as well; modern applications rely on RESTful web services delivering data to a diverse set of clients. The development landscape has changed, this talk will prepare you to face these challenges.

You spend your precious time building the perfect application. You do everything right. You carefully craft every piece of code and rigorously follow the best practices and design patterns, you apply the most successful methodologies software engineering has to offer with discipline, and you pay attention to the most minuscule of details to produce the best user experience possible. It all pays off eventually, and you end up with a beautiful code base that is not only reliable but also performs well. You proudly watch your baby grow, as new users come in bringing more traffic your way and craving new features. You keep them happy and they keep coming back. One morning, you wake up to servers crashing under load, and data stores failing to keep up with all the demand. You panic. You throw in more hardware and try optimize, but the hungry crowd that was once your happy user base catches up to you. Your success is slipping through your fingers. You find yourself stuck between having to rewrite the whole application and a hard place. It's frustrating, dreadful, and painful to say the least. Don't be that guy! Save your soul before it's too late, and come to learn how to build, deploy, and maintain enterprise-grade Java applications that scale from day one.

Topics covered include: parallelism, load distribution, state management, caching, big data, asynchronous processing, and static content delivery. Leveraging cloud computing, scaling teams and DevOps will also be discuss. P.S. This session is more technical than you might think.

Enforcing the cloud presence of an organization by exposing a RESTfull API is of extreme importance. It is a demanding and formidable task that can turn out to be either a great asset or a dire liability. This challenge is amplified by the vagueness of what a REST architecture is, and the diversity in approaches and opinions among the leading Web APIs.

This session attempts a balance between the spirit and philosophy behind REST, and the practicality and elegance inspired by the principles of modern API design. This very idea is highlighted through a series of concrete issues that frequently surface while building or evolving a mature REST interface whose goal is not only to be complete and feature-rich, but also intuitive and practical.

The rise of NoSQL is characterized with confusion and ambiguity; very much like any fast-emerging organic movement in the absence of well-defined standards and adequate software solutions. Whether you are a developer or an architect, many questions come to mind when faced with the decision of where your data should be stored and how it should be managed. The following are some of these questions: What does the rise of all these NoSQL technologies mean to my enterprise? What is NoSQL to begin with? Does it mean “No SQL”? Could this be just another fad? Is it a good idea to bet the future of my enterprise on these new exotic technologies and simply abandon proven mature Relational DataBase Management Systems (RDBMS)? How scalable is scalable? Assuming that I am sold, how do I choose the one that fit my needs best? Is there a middle ground somewhere? What is this Polyglot Persistence I hear about?

The answers to these questions and many more is the subject of this talk along with a survey of the most popular of NoSQL technologies. Be there or be square.

It was over 10 years ago that Spring hit the scene and made a big impact in the enterprise Java development ecosystem. Now that Spring 4.2 is available (and Spring 5 on the way), there's a lot of new features and a lot that you may not know about yet.

Whether you're already working with Spring 4 or are anxious to make a move up, there's plenty of new tricks Spring has in store for you. We'll explore them all in this overview of everything that's new in 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'll see how to build real Spring applications using Spring Boot. We'll also look under the covers to see what makes Spring Boot tick.

Spring offers a number of configuration options: XML configuration, Java configuration, and Groovy configuration to name a few. To some degree, component-scanning and autowiring help eliminate some explicit configuration. But in general most Spring applications require some essential “bootstrap” configuration to enable key functionality. What's the right way to build Spring applications when there are so many choices?

What if I told you that configuration was optional?

Spring Boot is an exciting new programming model for Spring that makes it extremely easy to create stand-alone, production-ready Spring applications. Rather than writing lots of code to satisfy the needs of a framework, Spring Boot helps you focus your coding efforts on your application. Spring Boot takes an opinionated approach to configuring Spring, making it possible to create Spring applications with little or, in some cases, no Spring configuration at all!

For over 10 years, Spring has been the go-to framework for developing powerful Java server applications. Increasingly, however, modern applications are placing heavier demands on the client side, expecting applications to be available anywhere, anytime, and on any device. In a client-rich world, where does Spring fit it?

In this session, we'll explore Spring's role in modern applications where the client can be on someone's desk or in someone's hands. We'll see how to take advantage of various Spring features and libraries to create a rich and responsive application that can run on a variety of devices.

“Docker is an open-source engine that automates the deployment of any application as a lightweight, portable, self-sufficient container that will run virtually anywhere.” Docker creates containers that provide running process with:

• an equal slice of CPU
• a maximum memory quota
• its own process ID (PID) namespace
• its own network interface
• its own private root filesystem

It does this by leveraging low-level Linux kernel primitives like cgroups and namepaces. The end result is a portable application container that can run anywhere Docker can run, including on VMs, bare-metal servers, OpenStack clusters, public instances, or combinations of the above.

Containers are an excellent way to package your application such that it can run consistently everywhere you want to run it, a fantastic step toward Continuous Delivery. In this session we'll look at how to use Docker to package, deploy, and run Java applications and other services. We'll also compare Docker to another container solution, Warden, which is a key component of the Cloud Foundry PaaS.

BOSH was originally developed to be the toolchain that installs and manages the Cloud Foundry runtime, which is a large distributed system consisting of multiple components running on multiple virtual machines. In order to deploy and manage such a system, you need elements of:

• configuration management tools, such as Puppet and Chef
• orchestration tools, such as Mcollective and RunDeck
• knowledge of multiple IaaS layers (compute, storage, networking) to support portability
• health management
• monitoring and reporting
• etc.

Fortunately, BOSH was written in such a way that it can be used to deploy not just Cloud Foundry, but any distributed system. Teams in multiple organizations are using it today to deploy:

• large-scale Jenkins deployments
• Hadoop clusters
• Cassandra and other NoSQL store clusters
• RabbitMQ and other message broker clusters

In this session we'll learn how to develop a BOSH release using the bosh-lite tool. We'll then learn how to create a deployment manifest, which maps our release to a specific infrastructure environment. Finally, we'll deploy our release to Amazon Web Services.

We make many assumptions when we develop our applications. Many of these assumptions no longer hold true when we start to build applications for the cloud. Cloud platforms also introduce architectural possibilities that do not exist in traditional deployment settings. This session will examine five architectural patterns that we can apply to our applications in order to prepare them for the unique characteristics of cloud environments.

We'll cover the following patterns:

• Microservice
• API Gateway
• Stateless / Shared-Nothing
• Configuration / Service Consumption
• Fault Tolerance

Examples will focus on the application of these patterns using Java/Spring and Cloud Foundry-based PaaS platforms, but should be applicable to any language/framework/PaaS platform combination.

Robert Martin assembled the SOLID family of principles to provide a useful guide to help us create object-oriented software designs that were resilient in the face of change. In recent years, the need to write highly-concurrent software in order to leverage increasingly ubiquitous multicore architectures, as well as general interest in more effectively controlling complexity in large software designs, has driven a renewed interest in the functional programming paradigm. Given the apparent similarity in their goals, “What is the intersection of SOLID with functional programming?” is a natural question to ask.

In this talk, we'll explore this intersection. We'll begin with a tour of the evolutionary patterns associated with enterprise software and programming paradigms, as well as take a look at the ongoing quest for best practices, the goal being to elucidate the motivation for examining this intersection of SOLID and functional programming. We'll then walk through each of the SOLID principles, examining them in their original object-oriented context, and looking at example problems and solutions using the Java language. Then for each principle, we'll examine its possible intersection with the functional programming paradigm, and explore the same problems and solutions using the Clojure language. We'll close by examining the transcendent qualities of the SOLID principles and how they can make any design simpler, regardless of the programming paradigm employed.

For much of the last two years I've delivered a two-part series at NFJS shows entitled “Effective Java Reloaded.” For all pracical purposes, it is an ala carte style rehash of the book Effective Java, written by Josh Bloch. One of my favorite parts of the discussion is of Item #15, which tells us to “Minimize Mutability.” If we turn this inside out, we're actually saying that we want to MAXIMIZE IMMUTABILITY. When we do this, we reap many benefits, such as code that is easier to reason about and that is inherently thread-safe. This can carry us a long way in the direction of program correctness and decreased complexity. However, when we start to program with immutability, several major questions arise.

First, the necessity of using a separate object for each distinct value, never reusing, or “mutating” an object, can quickly cause performance concerns. These concerns are amplified when we're talking about large collections such as lists and maps. These problems are largely solved by what we call “persistent data structures.” Persistent data structures are collections from which we create new values, not by copying the entire data structure and apply changes, but by creating a new structure which contains our changes but points at the previous structure for those elements which have not changed. This allows us to work with data structures in a very performant way with respect to time and resource consumption. We'll examine persistent data structures, their associated algorithms, and implementations on the JVM such as those found in the TotallyLazy library.

Second, because all of an immutable object's state must be provided at the time of construction, the construction of large objects can become very tedious and error prone. We'll examine how the Builder pattern can be applied to ease the construction of large objects, and we'll examine Builder implementations in Java and Groovy.

Third, we run into problems when we start to use frameworks that expect us to program in a mutable style. A prime example is Hibernate, which expects our persistent classes to follow the well-worn JavaBean convention, including a no argument constructor and getters and setters for each property. Such a class can never be mutable! So how do we program with frameworks such as Hibernate and yet still minimize mutability? The key is found in not letting frameworks dictate the way that you design your code. Just because the framework require something, don't let it force you to make the wrong decision. Use the framework as a tool to write your code, don't let your code be a tool of the framework. We'll examine strategies for doing exactly that.

You should come away from this talk better equipped to program in a way that minimizes mutability and maximizes immutability.

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.

This session will move beyond the basics cover Android persistence mechanisms, accessing RESTful web services, and more. We'll look at shared preferences, basic file I/O, and the Sqlite database. We'll also show how to operate off of the UI thread to access data from remote servers.

The application will access JSON data on a remote server, parse the data, and update the user interface based on the response.

The sea change in HTML 5 is likely to shift the pendulum away from today's thin-client based server-side web frameworks like Struts 2 and JSF to JavaScript powered next generation rich clients. With strong support for REST, WebSocket and JSON, Java EE 7 is well positioned to adapt to this change.

In this heavily code driven session, we will show you how you can utilize today's most popular JavaScript rich client technologies like AngularJS, Backbone, Knockout and Ember to utilize the core strengths of Java EE using JAX-RS, JSR 356/WebSocket, JSON-P, CDI and Bean Validation.

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. Scala-IDE is also available at the Eclipse Marketplace!

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.

Almost every example of an agile project involves a single team and while many successful projects are delivered that way, most enterprise software requires the interaction of several teams. But how do we scale agile beyond a single team? What practices translate and which ones don't? In this talk we'll discuss some of the issues you'll encounter as you move agile beyond a single group and how you can keep multiple stakeholders happy. While it isn't as simple as having a “scrum of scrums” it isn't as hard as replacing every line of COBOL.

Developers are flocking to client side frameworks and, as a result, there are more and more JavaScript libraries attempting to solve the rich internet application problem. In a space where new libraries seem to spring up weekly, what framework should you choose for your next project? While there is consensus around basic ideas like Model View Whatever, there are some strong philosophical differences amongst the various libraries. In this talk, we'll look at the similarities and the differences of some emerging JavaScript libraries discussing why you need to be aware of this rapidly evolving aspect of software development.

Technology changes, it's a fact of life. And while many developers are attracted to the challenge of change, many organizations do a particularly poor job of adapting. We've all worked on projects with, ahem, less than new technologies even though newer approaches would better serve the business. But how do we convince those holding the purse strings to pony up the cash when things are “working” today? At a personal, how do we keep up with the change in our industry?

This talk will explore ways to stay sharp as a software professional. We'll talk about how a technology radar can help you stay marketable (and enjoying your career) and how we can use the same technique to help our companies keep abreast of important changes in the technology landscape. Of course it isn't enough to just be aware, we have to drive change - but how? This talk will consider ways we can influence others and lead change in our organizations.

JAX-RS 2 is the new standard Java API for RESTful Web services and a major leap forward in the features and use cases covered by the API. The purpose of this technical session is to elaborate on all the new features being introduced as part of this major API revision.

This session explores the new client API, concepts behind filters and interceptors API, and asynchronous processing support. Other new features it covers include data validation support and improved support for hypermedia and server-side content negotiation. The last part of the session also briefly outlines future plans and focus areas.

Even with the recent explosion in alternative languages for the JVM, the vast majority of us are still writing code in “Java the language” in order to put bread on the table. Proper craftsmanship demands that we write the best Java code that we can possibly write. Fortunately we have a guide in Joshua Bloch's Effective Java.

In his foreward to the first edition, Guy Steele writes about the importance of learning three aspects of any language: grammar, vocabulary, and idioms. Unfortunately many programmers stop learning after mastering the first two. Effective Java is your guide to understanding idiomatic Java programming.

Effective Java is organized into 78 standalone “items,” all of which will be impossible to cover in one session. Instead I've chosen a subset of the most important techniques and practices that are commonly missed by today's Java programmers. You'll pick from a menu and decide where we'll head. Regardless of the path we take, you'll leave this session thoroughly equipped to write better Java code tomorrow!

The Cloud Foundry engineering teams have steadily increased their use of the Go programming language (http://golang.org) for building (or rebuilding) components, starting with the Router, and progressing through Loggregator, the “cf” CLI, and more recently the Health Manager 9000.

As a Java-developer-turned-DevOps-junkie focused on helping our customers and community succeed with Cloud Foundry, it's become clear to me that I need to add Go to my knowledge portfolio.

Go is a very interesting language, open-sourced by Google in late-2009, that takes a “less is more” (http://commandcenter.blogspot.de/2012/06/less-is-exponentially-more.html) approach to language design, but that also bakes in a powerful concurrency model.

This talk will introduce Go, delve into its distinctives, and contrast its approach with that of Java (where appropriate). We'll also write a fair amount of Go code along the way. This talk will be of particular interest to Java developers looking to add Go to their toolkits, but will also be of interest to anyone looking to learn a little bit more about Go.

You understand the Web. Why do you do REST so wrong?

Doing REST “right” isn't a matter of conformance or purity. It isn't about pleasing hard-to-please Restafarian personalities. It's about understanding that WYBIWYG (What you Build is What You Get). Decisions have consequences. You are free to design and implement whatever you like, but you need to understand the consequences of your choices.

REST, as defined by Roy Fielding's thesis, is a collection of architectural constraints designed to yield certain properties in deployed systems. When you take shortcuts, you simply will not receive all the benefits of loose-coupling, evolvable, flexible, scalable systems. URLs are not enough. HTTP is not enough. To fully embrace the world of REST, you must understand Hypermedia. The good news is that you already do, you've apparently just forgotten.

Here's the thing though. REST is not an endpoint, it is just a beginning. Come to this talk to hear how the story starts. We will take a deep dive into why the Web works, the implications for building Hypermedia-driven REST APIs and start to look at what this means in practice.

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.

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.

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.

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.

At the intersection of Big Data, Data Science and Data Visualization lives a programming language that ranks higher on the TIOBE index than Scheme, Fortran, Scala, Prolog, Erlang, Haskell, Lisp and Clojure.

The R language and environment is an open source platform that has quickly become THE language for analyzing data and visualizing the results. This talk will introduce you to the language, the environment and how it is being used with Big Data and Linked Data.

You don't need to be a stats head to attend this session. We'll introduce some basic concepts. If you are a stats head, there is plenty of material that you will still enjoy.

• History of R
• Language basics, data types and main structures
• Some statistics fundamentals
• R Graphics
• R and Big Data
• R and Linked Data

The cost of integrating information isn't cheap. Well, at least it isn't if you do it wrong. Chances are, you're doing it wrong.

The single most difficult aspect of data integration is the effort to achieve consensus. It isn't just that we are disagreeable people. It's also that it is a fantasy that there is a “common model” or a “global truth”. Different groups and individuals see the world differently and have different needs from information systems. Language, and therefore what we call things, isn't simply reflective of reality. It plays a constructive and interpretive role.

The problem is that our technologies force us to make choices about world views and pretend that things aren't changing constantly. This yields fragile systems and high impedance to change that cascades through our organizations. This translates to expensive, rigid and difficult to extend failure to give the business what they want.

Our friend Tim Berners-Lee and his Happy W3C Merrymakers have given us a set of technologies to help us solve these problems though. We forget that the Web he designed was not the public Web, but one to solve integration needs for complex organizations like CERN. The HTML bit that we have gotten so excited about is but a small part of the vision. We will introduce RDF and SPARQL as enabling technologies. They do not necessarily replace what you already have, but they do make it possible to share information with people you've never talked to: Collaboration without Coordination.

The surge of interest in the REpresentational State Transfer (REST) architectural style, the Semantic Web, and Linked Data has resulted in the development of innovative, flexible, and powerful systems that embrace one or more of these compatible technologies. However, most developers, architects, Information Technology managers, and platform owners have only been exposed to the basics of resource-oriented architectures.

This talk, based upon Brian Sletten's book of the same name, is an attempt to catalog and elucidate several reusable solutions that have been seen in the wild in the now increasingly familiar “patterns” style. These are not turn key implementations, but rather, useful strategies for solving certain problems in the development of modern, resource-oriented systems, both on the public Web and within an organization's firewalls.

Webs of documents are fabulous enough. Webs of data will blow your mind.

A table is a fixed structure. A tree is as well. A graph can go on forever and be extended at any time by anyone.

The Web is an unbounded graph. It is our definition of scale. What happens when we start to use it as the basis of sharing information, not just documents. This does not necessarily mean the public Web (although it is certainly appropriate for that as well). It simply means thinking of information as a web of linked entities through discoverable relationships.

Linked data is a way of doing this, but it is also an established project connecting billions of entities from disparate, unrelated sources. How does that even work? What can you do with such a thing? And what does that mean for your organization?

By building on the ideas introduced in the Data Integration talk, we will explore how webs of data built on standards can change everything.

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

JavaScript will celebrate it's 19th birthday in 2014. For a language that has been around for such a while it has seen very few, if any changes to the language itself. Well all that is about to change with ECMAScript.next (or ECMAScript 6). ECMAScript 6 modernizes JavaScript syntax, while bringing in features such as modules for better namespacing, class as a first class construct, and a variety of additional operators thus ensuring that JavaScript is ready for the next era of large scale modern web applications.

In this session we will take a look at some of the features that ECMAScript 6 brings to the table and see what kind of browser support is available for it.

Jamie Zawinski once said “Some people, when confronted with a problem, think “I know, I'll use regular expressions.” Now they have two problems.“. Many consider regular expressions to be indecipherable, but the truth is that every programmer should consider regular expressions an integral part of their toolkit. From the command line to your favorite text editor, from parsing user input to scraping HTML pages - once you know regular expressions you will find a use for them in almost every programming context.

In this session we will attempt to unriddle the mystery that regular expressions pose. We will start at the basics and work our way towards more complex expressions.

Gradle has fast become one of the de-facto build tool in the Java ecosystem. Gradle offers a powerful DSL to configure your builds. Whether you have a simple build, or a complex build with many moving parts, Gradle's DSL and extensible API can help you make your builds easier, and possible.

In this sessio we will start from the ground up. We will write our first Gradle script and examine Gradle's configuration vs. execution phases. We will see how Gradle uses plugins to add on functionality for free to your build and end with a look at the Gradle Plugin API to see how easy it is to write your own plugins for better reuse.

Finally, the Java 8 Date Time API will be in our grasps and now we will celebrate gleefully in the streets! ISO8601 and UTC standards! Immutability! Time to set attention to stun as this presentation will cover all the goods about the new Date/Time API that makes Java programming safe.

Finally, the Java 8 Date Time API will be in our grasps and now we will celebrate gleefully in the streets! ISO8601 and UTC standards! Immutability! Time to set attention to stun as this presentation will cover all the goods about the new Date/Time API in Java 8 that will finally make our code safer than before.

We cover in 90 Minutes:
ISO 8601 & UTC
Instants
Periods
Durations
Parsing
Time Zone Manipulations and Updates
Conversion from Old Java Date Times
Whatever else we can cram into the presentation

This will interactive for the most part with few slides. Bring on your questions.

This presentation covers the Guava library developed by Google (http://code.google.com/p/guava-libraries/). Guava provides collection extensions to the Java Collection API and, along with this, a cornucopia of time-saving utilities that bring Java as close as possible to some of the more functional and dynamic language competitors like Scala, Ruby, and Clojure.

This presentation focuses on the following topics: how to make Predicates and Functions; how to use new collection constructs that make life easier, including MultiMap, BiMaps, and MultiSets; how to set up and use Guava preconditions; and how to create truly immutable collections, and more. All of this is done with Java.

Presentation on Akka. A set various tools to write concurrent, fault-tolerant applications using immutable data, asyncronous message passing using local and remote actors, software transactional memory, and supervised systems.

Akka is a middleware, but it is not your 1990s middleware. Akka is a set of various tools to write concurrent, fault-tolerant applications using immutable data, asyncronous message passing using local and remote actors, software transactional memory, and supervised systems. Akka is also part of the Typesafe stack, a stack that include the Play web framework and the Scala programming language. This Akka presentation will cover both Scala and Java style usage of Akka and give the audience a 30k view of how it comes together. While this presentation is not interactive, all demos will be available on github for those that want to “play” along with their laptops.

The presentation will cover an introduction on the framework by creating a basic web application in both Java and Scala to get you started.

The Play Framework is a lightweight and stateless web framework that is part of the TypeSafe stack, a stack which includes Akka middleware and the Scala programming language. The presentation will cover an introduction on the framework by creating a basic web application in both Java and Scala to get you started. The presentation will also cover javascript library integration and explain the philosophy behind the framework and give an honest analysis on the advantages and disadvantages of the framework. While this presentation is not interactive, all demos will be available on github for those that want to “play” along with their laptops.

The software industry changes rapidly, but you can protect yourself
from these changes by creating code that is complicated enough that
only you can maintain it.

Of course you should not engage in obvious bad practices. The good
news is that you don't have to. You can follow idiomatic industry
practice and stay buzzword compliant with the latest trends, while
quietly spreading complexity throughout systems. Better yet, the
symptoms will show up not in your own code, but in other code that
uses your code, directly or indirectly. You will be a hero as you
lead larger and larger teams burning the midnight oil to keep systems
alive.

Practice these principles, and your code will have an
infectious complexity that guarantees you will always be needed to
maintain it.

• Use OO, and don't forget those setter methods!
• Prefer APIs over data.
• Start with DSLs.
• Always connect (and never enqueue).
• Create abstractions for information.
• Use static typing across subsystem boundaries.
• Put language semantics on the wire.
• Write lots of unit tests.
• Leverage context.
• Update information in place.

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.

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.

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.

Using continuous integration, we will explore how to take an existing build, test, deploy process and shorten the time from code to deploy from days to minutes .

Bootstrap your current build into a build always process providing rapid feedback. We will show the basic of a continuous build process and how quickly you can add in continuous inspections, tests and deployment to increase collaboration, quality and productivity. We will explore how to take an existing build, test, deploy process and shorten the time from code to deploy from days to minutes .

Learn how Kanban can lead your team or organization to a sane approach to dealing with too much work while addressing problems quickly in a collaborative environment that drives continuous improvement.

Kanban can be used as a lightweight process to manage the process of a small development team or production support team. It is also used as the engine of a large-scale Agile Enterprises. We will explore the simplicity of Kanban and discipline required to adhere to the basic principles and practices of Kanban. Learn how Kanban can lead your team or organization to a sane approach to dealing with too much work while addressing problems quickly in a collaborative environment that drives continuous improvement.

Where do defects come from? Technical debt is often one of our biggest challenges as poor design and defects are built up over time by cutting a corners here and there. We will discuss some key technical metrics that can shine light on these defects before they get out of control and find those that are out of control and worth your attention now.

We'll explore how the psychological effect of simply measuring technical metrics and making them visible can have immense impacts on reducing the occurences going forward.

The single most important tool in any developers toolbox isn't a fancy IDE or some spiffy new language - it's our brain. Despite ever faster processors with multiple cores and expanding amounts of RAM, we haven't yet created a computer to rival the ultra lightweight one we carry around in our skulls - in this session we'll learn how to make the most of it. We'll talk about why multitasking is a myth, the difference between the left and the right side of your brain, the importance of flow and why exercise is good for more than just your waist line.

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!

Service-Oriented Architecture (SOA) has become an ugly word in the industry. Not only is everyone more confused than ever about what SOA is, but the tooling and products surrounding SOA has made it into a ubiquitous buzzword that has little or no meaning these days. That said, SOA as an architecture pattern is still very much alive and solves many issues within a service-based architecture approach. So what is SOA from an architecture standpoint? In this product-free session we will take a detailed look at SOA from an architecture pattern point of view, understand how abstraction plays a part in SOA, and also understand the implementation aspects of the pattern. At the end of this session we will look at a few service bus considerations, including dealing with single point of failure scenarios, performance bottleneck issues, and service bus roles and responsibilities.

Agenda:

• architecture pattern elements
• forms of abstraction
• pattern implementation (no products!)
• service bus considerations

Enough with the darn JavaScript frameworks already! There's nothing wrong with a judicious use of this ubiquitous programming language, but it's gotten a little out of hand. What if there were an evolvable future state of declarative and encapsulated user interface elements that was available today in most modern browsers?

There is! The Polymer Project is a young but impressive glimpse into where things should go.

It's goals are:

• Use the platform
• Everything is an element
• Eliminate boilerplate

This talk will introduce you to:

• The Polymer Project
• The strategy for supporting today's browsers with tomorrow's technologies
• Application frameworks that build upon these core technologies
• Custom visual and non-visual elements
• The underlying W3C Specifications that engender all of this

“Computers are useless. They can only give you answers.” –Picasso

If everything is explicitly described in uniform, robust and comprehensive data models, it is easy to imagine how to ask questions of the data. The social, technical and financial costs of getting the information into that state, however, will keep that from ever being a reality. So, how can we integrate and reason over choppy and sloppy data from multiple sources in a variety of formats? We will see how the RDFS and Web Ontology Language (OWL) W3C standards help us connect and reason over content that leaves things unsaid without writing a bunch of custom code.

This is not artificial intelligence, but it is influenced by work done in that field.

Even taking into account everything that we've learned about operating at “web scale” in the last several years, most applications are designed and implemented to be, as Michael Nygard highlights in his book Release It!, “feature complete” not “production-ready.” Unfortunately, the architectural patterns associated with operating at scale – notably the move toward “micro-services” – introduce an order of magnitude more ways in which our applications can fail. If we do not plan well for failure, we will experience the ultimate failure. But if we do plan well for failure, we have a fighting chance at success.

This talk will take a tour through the James Chiles' book Inviting Disaster: Lessons From the Edge of Technology, and examine what we can learn from engineering fields in the physical world, applying those learnings to the way in which we develop fault tolerant applications.

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 look at some JavaScript patterns, and how you can use them within your code.

No longer can you think of JavaScript as a kiddie-scripting language. JavaScript has now been promoted to a first-class citizen within your application - and with this, comes the need to think of better abstractions, code re-use - even thinking of establishing a common vocabulary to discuss approaches to writing better, cleaner and ultimately more maintainable JavaScript code.

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.
