Part two of this workshop takes a deeper dive in application, integration, and enterprise architecture topics, including evaluating architectures via Agile ATAM, the impacts of continuous delivery on architecture, comparing architectures, SOA, SOAP, and REST, integration hubs, and enterprise architecture approaches and strategies.

The job Software Architect places in the top ten of most annual surveys of best jobs, yet no clear path exists from Developer to Architect. Why aren't there more books and training materials to fill this demand? First, software architecture is a massive multidisciplinary subject, covering many roles and responsibilities, making it difficult to teach because so much context is required for the interesting subjects. Second, it's a fast moving discipline, where entire suites of best practices become obsolete overnight.

To fully leverage knowledge, you need application. Part three of this workshop uses the public domain Architectureal Katas exercise to apply learnings from the first two parts.

To fully leverage knowledge, you need application. Part three of this workshop uses the public domain Architectureal Katas exercise to apply learnings from the first two parts.

From the Architectal Katas website:

Architectural Katas are intended as a small-group (3-5 people) exercise, usually as part of a larger group (4-10 groups are ideal), each of whom is doing a different kata. A Moderator keeps track of time, assigns Katas (or allows this website to choose one randomly), and acts as the facilitator for the exercise.

Each group is given a project (in many ways, an RFP–Request For Proposal) that needs development. The project team meets for a while, discovers requirements that aren’t in the orignal proposal by asking questions of the “customer” (the Moderator), discusses technology options that could work, and sketches out a rough vision of what the solution could look like. Then, after they’ve discussed for a while, the project team must present their solution to the other project teams in the room, and answer challenges (in the form of hard-but-fair questions) from the other project teams. Once that challenge phase is done, the room votes on their results, and the next project team takes the floor.

Part 3, Architectal Katas, is an instructor-led hands-on Katas exercise.

The new facilities in Java 8 is about the change the way we write code. Our code will become
more expressive and concise. But, exactly how?

In this presentation we will take several common Java code examples, discuss the core idea expressed in code, and transform that code to use the facilities in Java 8. Watch and interact as you see Java code go through a weight loss program right in front of your eyes.

Functional programming has gained the recognition it deserves and almost all mainstream languages now support functional style of programming. With the introduction of lambdas in Java 8, we have new tools on our hands. In this presentation, we explore this tool and how we can benefit from it.

We start with an introduction to lambda and learn about imperative vs. declarative style and learn how to solve some common problems with it.

We all have heard about lambda expressions in Java 8. The real unsung hero of Java 8 are the Streams.

In this presentation we will take an example driven approach to explore streams, their core capabilities form the application development point of view, and how to explore these capabilities for improve performance and efficiency.

Functional programming is receiving much attention recently. Most mainstream languages, including C++, Java, and C# now support lambda expressions and functional style. Why is there a sudden interest in adapting something that was largely ignored for decades? What are the technical reasons, how do we benefit, in what ways can using these techniques make our applications better and our development efforts easier as well?

In this technical presentation we will learn about the technical underpinnings of functional programming, the fundamental problems they address, and the large impact of those on application development

Big data, smart phones, tablets, wearable devices, multicore processors,…—we're seeing rapid and drastic
evolution in both the computing environments and the application needs. Thankfully, a number of technologies have been evolving over the past several years to meet these demands. The reactive manifesto is an attempt to reenforce a set of technical practices needed to meet the emerging demands.

If you've heard and read about reactive programming, but are eager to realize that in code, then this presentation is for you. We will start with a rapid introduction and get into code to learn about reactive programming, not in theory but with practical examples.

At the end of the day, an architect's primary job is to communicate. Not only do we need to make sure our teams understand the design of the system well enough to implement it, we must be able to explain our decisions to an audience that isn't impressed with how many TLAs you can rattle off in one sentence. Successful architects need to seamlessly transition from in depth technical conversations to budget meetings to discussions with end users adjusting the message to fit the audience.

While oral communication is key, good architects also spend a good deal of time putting pixel to screen via email, IM and various architectural documents we're expected to create. We need to write clearly and concisely while also knowing when the best course of action is to pick up the phone or walk to someone's desk.

In this talk, we'll explore the various methods that we as architects use to communicate with our stakeholders. We'll talk about knowing our audience, being able to present as well as how to run a good meeting. We'll discuss various patterns (and antipatterns) of presenting along with some concrete advice on how to do it better. At the end of the day, our job is to tell effectively tell a story - this talk will look at ways to do that.

Big up front design is discouraged in agile development. However, we know that architecture plays a significant part in software systems. Evolving architecture during the development of an application seems to be a risky business.

In this presentation we will discuss the reasons to evolve the architecture, some of the core principles that can help us develop in such a manner, and the ways to minimize the risk and succeed in creating a practical and useful architecture.

Creating code is easy, creating good code takes a lot of time, effort, discipline, and commitment. The code we create are truly the manifestations of our designs. Creating a lightweight design can help make the code more extensible and reusable.

In this presentation we will take an example oriented approach to look at some core design principles that can help us create better design and more maintainable code.

“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.

Building and running container images isn’t enough. There are very real problems that we still have to solve:

• how do we schedule and run these containers on infrastructure?
• how do we create networks that can link these containers across multiple hosts?
• how do we handle data that needs to persist across container restarts?
• how do we handle concerns like service discovery and load balancing?

These concerns are the focus of much of the development work being done in the Docker ecosystem today.

We’ll examine the use of several projects and how they contribute to solutions to these problems, including:

• Kubernetes by Google
• Apache Mesos
• Cloud Foundry Diego
• Cloud Foundry BOSH
• Weave
• CoreOS
• The Hashicorp family of projects

Inspired by success stories from companies such as Amazon and Netflix, many organizations are moving towards microservice architectures at a brisk pace. This session provides a thorough overview of the pros and cons for microservice architectures, when it is applicable, and some nascent best practices.

Microservice architecture is important because it’s the first architecture to fully embrace the Continuous Delivery and DevOps revolutions. In this session, I cover the motivations for building a microservice architecture (including making the distinction between “regular SOA” and microservices), some considerations you must make before starting (such as transactions versus eventual consistency), how to determine service partition boundaries, and ten tips to dowse you towards success. I also discuss the role of polyglot development, enterprise governance, how data and databases fit into this new world, and tooling to help ensure consistency between core services like logging and monitoring. This session provides a thorough overview of the pros and cons for microservice architectures, when it is applicable, and some nascent best practices.

Part 1 of this workshop focuses on the many elements required to make the journey from developer to architect, covering process topics like the impact of Continuous Delivery on architecture, technical subjects like application, integration, and enterprise architecture, and soft skills. While we can't make you an architect overnight, we can start you on the journey with a map and a good compass.

In this session, we will take a look at Angular - the powerful MVVM SPA framework from 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

In this session we will take a look at Angular and using it to develop 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 and scoping rules
• ng-model
• Controllers, Dependency Injection, and the View-Model
• Looping using ng-repeat
• Forms using ng-form, form validation and submission in AngularJS
• ng-messages to display form validation messages to the user
• Angular provided filters and custom filters

See “Detail” for a list of topics I cover and the Github repo URL

In this session we continue our discussion from Part I. As we continue to evolve our application we will seek to use, and understand a few more of AngularJS' core constructs.

• Factories and services
• Routing using ng-view and $routeProvider
• AJAX calls to a backend using $http

If time permits we will look at a few good practices when developing AngularJS applications, ways to modularize your code, and some tools that aid in the development of AngularJS applications.

Visualizing data often requires that the visualization be updated on data changes, or in response to user input. As we know, a key strength of AngularJS is its 2-way binding and apply/digest cycle which makes keeping the view and data-model in sync painless. This makes creating dynamic visualizations with or without interactive data a breeze with Angular.

This is a 2 session series. In this first part we will look at some of the underlying constructs in D3, and AngularJS directives. The second part of this session will attempt to bring these 2 together to allow us to enable dynamic visualizations in Angular.

This is my story of lessons learned on why improvement efforts fail… I had a great team. We were disciplined about best practices and spent tons of time on improvements. Then I watched my team slam into a brick wall. We brought down production three times in a row, then couldn’t ship again for a year.

Despite our best efforts with CI, unit testing, design reviews, and code reviews, we lost our ability to understand the system. We thought our problems were caused by technical debt building up in the code base, but we were wrong. We failed to improve, because we didn’t solve the right problems. Eventually, we turned our project around, but with a lot of tough lessons along the way.

In this talk, we'll go through a deep-dive case study that starts with project failure, then revisit all the mistakes we made over a 3 year journey to turn the project around. We'll discuss bad assumptions, strategies that failed, ideas that changed, techniques and tools that changed, and how we eventually learned our way to victory.

After reviewing each mistake, we'll have a group discussion about the underlying reasons, so you can avoid these mistakes on your own project.

JavaScript will celebrate it's 24th birthday in 2020. 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. ES 7, 8, 9 and now 10 all use the features introduced by ES6 to further the language.

In this session we will take a look at some of the features that ECMAScript 6 / 7 / 8 / 9 and 10 bring to the table. We will take an exploratory approach, and by the end of 3 hours, you will be well versed with ALL of the new features in JavaScript.

The first part of the Continuous Delivery workshop covers the differences between continuous integration, continuous deployment, and continuous delivery). It also introduces the deployment pipeline_, along with usage, patterns, and anti-patterns. This part concludes with some applied engineering principles.

Releasing software to actual 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. The workshop materials are derived from the best selling book Continuous Delivery and creating in collaboration with the authors and other of my ThoughtWorks colleagues. Continuous Delivery details how to get fast feedback on the production readiness of your application every time there is a change—to code, infrastructure, or configuration.

The first part of the workshop describes the technical differences between related topics such as continuous integration, continuous deployment, and continuous delivery. 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. I discuss the various stages, how triggering works, patterns and anti-patterns, and how to pragmatically determine what “production ready” means. This session also covers some agile principles espoused by the Continuous Delivery book, including new perspectives on things like developer workstations and configuration management.

Continuous Delivery relies on a variety of interlocking engineering practices to work efficiently; this session covers three related topics. First, I cover the role of testing and the testing quadrant. Second, I specifically cover version control usage and offer alternatives to feature branching like toggle and branch by abstraction. Third, I describe some incremental release strategies, along with their impact on other stages of project lifecycle.

Continuous Delivery relies on a variety of interlocking engineering practices to work efficiently; this session covers three related topics. First, I cover the role of testing and the testing quadrant, including the audience and engineering practices around different types of tests. I also cover some best practices around testing, including testing ratios, code coverage, and other topics. Second, I specifically cover version control usage and offer alternatives to feature branching like toggle and branch by abstraction. Generally, I talk about building synergistic engineering practices that complement rather than conflict one another. In particular, I discuss why feature branching harms three other engineering practices and describe alternatives. Third, I describe some incremental release strategies, along with their impact on other stages of project lifecycle.

Two big stumbling blocks for Continuous Delivery adaptation are interactions with operations and the keepers of data. First in this session, I cover operations, DevOps, and programmatic control of infrastructure. Second, I discuss how to incorporate databases and DBA's into the Continuous Integration and Continuous Delivery process.

Two big stumbling blocks for Continuous Delivery adaptation are interactions with operations and the keepers of data. First in this session, I cover operations, DevOps, and programmatic control of infrastructure using tools like Puppet and Chef. I also discuss the explosion of tool alternatives in this space, and cover some current-day best practices. Second, I discuss how to incorporate databases and DBA's into the Continuous Integration and Continuous Delivery process. This includes database migrations, strategies for enhancing collaboration between application development and data, and database refactoring techniques.

Today, we all benefit from the sophistication of modern compilers and hardware, but that extra complexity can also make it difficult to reason about performance.

In this talk, we'll examine some surprising performance cases and learn how to
use profiling and benchmarking tools to better understand our modern execution environments.

Early releases of Java performed poorly, but those issues largely disappeared long ago with the introduction of HotSpot. However, much of the performance advice for Java persists through hearsay from those early days.

In this talk, we'll forget the hearsay and take an objective look using benchmarking and profiling tools to find out which optimizations matter today and just as importantly those that don't.

Unlike earlier languages, Java had a well-defined threading and memory model from the beginning. And over the years, Java gained new packages to help solve concurrency problems.

Despite this, Java concurrency is sometimes subtle and fraught with peril.

In this talk, you'll learn these subtleties. And finally, you'll learn how to handle concurrency by exploring the concepts behind java.util.concurrent and other concurrency libraries.

The drive to continuous delivery, micro services and PaaS includes the need to auto scale and potentially auto provision services. This session will identify the legacy thinking of a statically partitioned world and drive to the scalable world of Apache Mesos.

This session will look at the failings of the many of today's cloud technology, identify the goals we have and look into the tooling of how to get there. In this session we will look at:

• static vs elastic partitioning
• vm vs containers
• separating cluster capacity from application scale
• load balancing with HAProxy

This session will be packed with demonstrations.

If there is a safe bet, it is that everything fails. From hard drives to power supplies, from routers to software, everything fails. Frankly a planned upgrade of a production service is planned down time, or a failure to continue services for a planned period of time.

This session will look at planning for failure by deploying into an Apache Mesos cluster.

This session will delve into how Apache Mesos identifies failures and how it protects from them. It will also look at how to upgrade infrastructure without down time.

Despite our best efforts with Agile best practices – CI, unit testing, design reviews, code reviews – every few years we end up rewriting our software.

This talk is about my personal experiences with project failure, improvement failure, patterns across the industry, and the key lessons that were critical to success. I had a great team. We were disciplined with best practices and spent tons of time working on improvements. Yet still, I watched my team slam into a brick wall. We brought down production three times in a row, then couldn't ship again for another year.

We thought our problems were caused by technical debt building up in the code base, but we were wrong. We failed to improve, because we didn't solve the right problems. Eventually, we turned our project around, but with a lot of tough lessons along the way.

When I started consulting, I saw the same patterns across the industry:

Our problems are invisible. They're hard to measure, hard to explain. We rely primary on gut feel to make improvement decisions, and it's really easy to make improvements that don't make much difference.

The relentless business pressure never lets up, and developers don't have control. Without visibility, management makes ill-informed decisions, train-wrecks our projects, and drives the development team to exhaustion.

I turned the lessons I learned into the Idea Flow Learning Framework, a data-driven feedback loop for guiding improvements. By quantifying the impact of disruptions, test maintenance, confusing code, and collaboration problems, we can find our biggest problems, understand the causes, and align our development priorities with leadership.

React.js is a view library from Facecbook for building performant user-interfaces in JavaScript. In this session, we'll explore React.js and understand why it's a great step forward for building complex UI's that run fast. We'll code up an example web application using React.js and step through the basics of using the library while discussing concepts like the virtual DOM and components.

In this session, we'll explore React.js and understand why it's a great step forward for building complex UI's that run fast. We'll code up an example web application using React.js and step through the basics of using the library while discussing concepts like the shadow DOM and components.

In this session, we'll dig deep into the performance aspects of JavaScript and the Web Browser. Single page web applications are becoming popular very quickly, and understanding the low-level and high-level aspects of the browser platform and JavaScript runtimes embedding in them are important.

We'll cover topics such as browser pipe-lining, memory management, testing and measuring performance.

The usage of JavaScript on the server is rising. In this session, we'll talk about all the tools and utilities that comprise a modern JavaScript application, from a server-side point of view.

The usage of JavaScript on the command line and server has exploded over the past couple of years. Node.js has become popular with development shops from startups to big corporations. With its asynchronous nature, JavaScript provides the ability to scale dramatically. Along with the ability to drive your server-side applications, there are a number of tools that help with all aspects of browser development: testing, packaging, and deployment. In this session, we'll explore these tools and show you how you can incorporate these into your environment.

JavaScript has first class support for functional programming. There are many techniques for writing code in more clear, and concise form, in JavaScript using these techniques. In this session, we'll explore these techniques and talk about how to implement them. We'll use commonly used libraries like underscore to make elegant JavaScript code.

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 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!

You wouldn't write your entire application in a single main() method or servlet. Nor would you develop an entire production-ready application in a single class. It's even unlikely that you'd cram everything into a single package.

Modularity helps us gain order in our code, breaking it into easily digestible, refactorable, pluggable, and testable chunks. Classes and methods are a form of modularity that we're all familiar with. But once the code is built, modularity goes away and we're left deploying a single WAR file.

Aside from being buzzword-compliant, Microservices are a means of defining entire systems from composable, but distinct deployment units gaining all of the benefits of finer-grained modularity. As it turns out, Spring is well-equipped as the platform on which we can build and deploy microservices.

In this session, we'll examine the details of microservices and explore the features of Spring, Spring Boot, and Spring Cloud that enable you to achieve modularity via microservices.

How do you test a Spring application? The easy answer is that Spring encourages loose-coupling through interfaces and dependency injection, therefore it's easy to inject mock implementations at test time.

But, as I said, that's the easy answer.

There's more to testing an application than simple unit-testing. And the most challenging parts of an application to test are the external edges such as the web and database portions. It's difficult to inject a mock user into a web application; and injecting a mock database doesn't give any confidence that persistence code will work with a real database.

In this session, we'll look at various ways that Spring and Spring Boot help with testing the tough-to-test portions of an application.

The Semantic Web and its related technologies provide an incredibly powerful model for driving the cost of data integration down to nearly zero. So, how do we deal with developers who are overwhelmed, frightened or annoyed by its data models and formats?

We really do not have to devolve into Webs of Haves and Have nots when it comes to semantically rich, interoperable data and modern application tools, frameworks and user interfaces. There is a surprisingly simple mechanism by which “normal” developers can benefit from the power of the Semantic Web and the latter's developers can integrate with the panoply of tools and toys under constant development by the former.

The trick is JSON-LD. A simple, but deliberately designed extension to JSON that bridges both worlds and is finding its way into many other uses by the likes of Google and GitHub.

We will learn about:

• the JSON-LD format
• how to frame, sign and validate it
• how to convert it to/from RDF
• how to describe Hypermedia systems with Hydra and JSON-LD
• how to embed and consume JSON-LD in HTML documents
• how JSON-LD is being used in a variety of mass market ways

Encryption is a powerful tool for privacy. At least that is what we're meant to think.

If you consider encryption to be a black box of magic, you should probably attend this talk.
If you think encryption will protect your secrets, you should probably attend this talk.
If you have (or haven't) been following the news, you should probably attend this talk.

The truth is, encryption can be an effective way of making it harder for people to steal your secrets. But it isn't magical, it isn't fool proof and, depending on how you are using it, may be completely useless. It is a hard topic that we'll only touch the surface on, but there are very few topics that are more crucial for our industry and profession to understand better than encryption. You don't have to understand the math (although that will help), but you do have to understand what it will and won't do for you*.

*and how implementations of it may have been intentionally compromised

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.

We started with documents on the Web. Then we realized we could share data using the same technologies. And then services. Concepts were next to help us organize all of this information. And now, we want Things on the Internet and Web too. Fortunately, we already have much of the infrastructure to welcome all of these new physical information producers and consumers to the party.

This talk will be a high level overview of how the Internet of Everything scales to accept entire new classes of devices and how we make sense of it all. We will also look toward the future of where we are going next.

Test Driven Design, we hear is a great way to create lightweight design that is easier to maintain and evolve. Unfortunately, just writing test cases mechanically do not lead to good design. In fact, it may really not lead us anywhere we want to really go!

In this presentation we will discuss some of the challenges with using test driven development, look at practical and pragmatic solutions that will help us make a good use of this wonderful design tool.

In some organizations, architects are dismissed as people that draw box and arrow diagrams - the dreaded whiteboard architect. While we don't want to foster that stereotype, it is important for an architect to be able to construct basic architectural diagrams. An architect must also be able to separate the wheat from the chaff eliminating those models that don't help tell the story while fully leveraging those that do.

In this workshop, we'll discuss the various diagrams at our disposal. We'll walk through a case study and as we go, we'll construct a set of diagrams that will help us effectively communicate our design. We'll talk about stakeholders and who might benefit from each typ of diagram. Additionally we'll discuss how to constructively review an architectural model.

Workshop Requirements

Neither a laptop nor special software is required for this workshop though your modeling tool of choice (Spark, Visio, OmniGraffle, etc.) is welcome for the exercises. Of course paper and pencil are very effective too and frankly recommended! Feel free to work in pairs or teams. That's it! Well, and a willingness to participate!

Neither a laptop nor special software is required for this workshop though your modeling tool of choice (Spark, Visio, OmniGraffle, etc.) is welcome for the exercises. Of course paper and pencil are very effective too and frankly recommended! Feel free to work in pairs or teams. That's it! Well, and a willingness to participate!

Scala for Java Developers is a full live code and fast paced presentation and workshop (laptops optional), and this is all about the Scala language.

Scala is a wonderful functional/hybrid language. It will become one of the 5 languages that you will need to know to be a highly successful JVM developer in the very near future (others being Groovy, Clojure, Java 8, and JRuby). Scala, as opposed to some of the other languages, has quite a learning curve. This presentation was built for questions. We will start with some basics, how this presentation will flow and end will be up to you, the audience. Bring your intellect, curiosity, and your questions, and get ready for some Scala. Laptops optional so you can try stuff out on your machine and create questions of your own!

Workshop Requirements

Some things will be required if you to participate in the workshop

• A modern JDK installation. JDK 1.8+ 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.

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 Scala 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. But it is preferred to do the installation before the event.

For MacOSX:

• Download brew package manager at http://brew.sh
• At a console type: brew install scala

For Windows

• Visit http://scala-lang.org/download
• Download the .msi package
• Install the .msi package

For Linux

• Download the tar.gz package
• Extract the package to your favorite directory
• Export SCALA_HOME to your Scala directory (scala-2.11.x)
• Add to your PATH: $SCALA_HOME/bin

You may also 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. You can either download the complete Scala IDE which includes the complete Eclipse download. You can also download the plugin. 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, although I would recommend getting the latest instructions from scala-ide.org

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

VSCode - Download the “Scala Language Plugin” from the plugins within VSCode.

That is it. Hope to see you soon.

Didn't you hear the news? TDD is dead. Yet many developers rely on it for quality code. Come join the zombie apocalypse and learn and understand TDD, what sets it apart from unit testing after the fact, what to do when you need to update code, effective mocking, automatically generating test data and lots of it, leaving code alone and respecting your work, and more

This presentation will cover:

• What is TDD?
• Benefits of TDD
• How to TDD
• Mocking
• The Great TDD Debate
• Opinions of TDD from Industry Leaders
• JVM Testing Tools
• JVM Testing Languages
• Testing Static Calls
• Updating Code

This 2015 presentation covers the Guava library developed by Google. 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/or dynamic language competitors like Scala, Ruby, and Clojure. Why a brand spanking new 2015 version of this presentation? Well, there more new stuff to learn and use!

This presentation covers briefly on the tried and true stuff like functions, predicates and how they interact with Java 8. It covers how to use new collection constructs that make life easier, including MultiMap, BiMaps, and MultiSets, immutable collections, handling Futures with callbacks and shutdowns, caches, and then we will dwell on tons of the newer features that came with Releases 16, 17, and 18.

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.

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.

Java 8 is the biggest change to the Java language ever. The addition of lambdas, functional interfaces, and streams fundamentally changes the programming model for applications. This talk summarizes those changes, along with optionals, method references, and other new features of the language.

Demonstrations will include the map/filter/reduce mechanism, the streaming API, how to write functional interfaces, predicates, suppliers, consumers, method references, default methods in interfaces, optionals, and more.

Time is very precious and is often threatened by phone calls, emails, co-workers, bosses, and most of all, yourself. The Pomodoro Technique reigns in unfocused time and gives your work the urgency and the attention it needs, and it's done with a kitchen timer.

In this presentation we discuss how to set up, estimate time, log time, deal with interruptions, and integrate with Agile as a team. We discuss timer software and even some of the great health benefits of the Pomodoro Technique.

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.

Good architects are, almost by definition, good story tellers. And while good communication skills are vital to success as an architect, so too is an ability to constructively critique an architecture. In this talk, we'll explore why reviews are important and what it takes to perform them well. Additionally, we'll talk about the importance of planning and preparation in conducting a successful review.

HotSpot provides a variety of garbage collectors with a variety of strengths and weaknesses. To get the most out of our applications, we need to pick the right garbage collector and design to take advantage of its strengths and avoid its
weaknesses.

In this presentation, you'll learn about criteria for picking a garbage collector, how to measure GC performance, and how to write code that works with rather than against the GC.

Modern applications are changing as we embrace the engineering practices associated with Continuous Delivery and DevOps, migrate our applications to modern cloud platforms, elastically scale applications with the dynamics of customer demand, and embrace microservices architectures. The Twelve-Factor App is a collection of application development patterns developed by Heroku engineers that aim to support these types of architectural and cultural change.

The 12 Factors are:

1. One codebase tracked in revision control, many deploys
2. Explicitly declare and isolate dependencies
3. Store config in the environment
4. Treat backing services as attached resources
5. Strictly separate build and run stages
6. Execute the app as one or more stateless processes
7. Export services via port binding
8. Scale out via the process model
9. Maximize robustness with fast startup and graceful shutdown
10. Keep development, staging, and production as similar as possible
11. Treat logs as event streams
12. Run admin/management tasks as one-off processes

We’ll examine how to implement these factors using JVM “microframeworks” like Spring Boot and Dropwizard.

Microservice architectures place great emphasis on autonomous product teams that develop and deploy equally autonomous services using decentralized release management, testing, and deployment strategies. I don’t have to wait on you to deploy my service, and you don’t have to wait on me. And yet the complexity associated with managing these large, distributed systems seems like it would demand even greater discipline and centralized coordination of testing activities. Fortunately, while greater discipline is in fact required, we don’t require the centralized coordination that would seem to destroy many of the benefits of embracing microservices. In this session will examine principles and practices that will help us develop an effective testing strategy for microservices.

Topics will include:

• who moved my trust boundary?
• expressing API’s as versioned contracts
• what’s in a contract? the good, the bad, and the ugly
• leveraging consumer-driven contracts
• exploratory testing for risk discovery
• recovery OVER prevention
• dogfooding

Groovy is unusual among programming languages in that it doesn't seek to replace its predecessor. You can freely mix Groovy with Java on a class-by-class, or even line-by-line, basis. If you are working with Java, there's no reason not to make your life easier by adding Groovy where it helps the most.

Groovy helps Java in many ways, especially when processing XML or JSON data, replacing anonymous inner classes, adding tons of library methods that Java has needed all along, vastly simplified file and database manipulation, and much more. This talk will demonstrate how you can add Groovy to Java applications and simplify your development job immediately.

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.

Grails is no longer the web framework you remember. Based on Spring Boot and complete with profiles and JSON views, Grails is now an excellent way to build micro-services, access NoSQL databases, provide a powerful REST API, and more.

Grails can do everything Spring Boot can do and more. It combines sophisticated Groovy DSLs with asynchronous capabilities, a newly redesigned data services layer, and more.

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.

Visualizing data often requires that the visualization be updated on data changes, or in response to user input. As we know, a key strength of AngularJS is its 2-way binding and apply/digest cycle which makes keeping the view and data-model in sync painless. This makes creating dynamic visualizations with or without interactive data a breeze with Angular.

This is a 2 session series. In this first part we looked at some of the underlying constructs in D3, and AngularJS directives. This second part will attempt to bring these 2 together to allow us to enable dynamic visualizations in Angular.

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.
