Many of us would love to embrace microservices in our day-to-day work. But most of us don’t have the opportunity to start over with a pure greenfield effort. We have to understand how to refactor our existing monolithic applications toward microservices. Practical steps include building new features as microservices, leveraging anti-corruption layers, strangling the monolith.

In this presentation we’ll go light on the theory and walk through the actual process of turning a strawman monolith into a family of well-factored microservices.

As we build distributed systems composed of microservices, we introduce new potential performance problems and failure points. As the number of nodes in our system increases, these problems rapidly amplify. In order to keep our composite systems responsive, we can apply the techniques of reactive programming. In order to keep our composite systems healthy, we can apply fault tolerance patterns like circuit breakers and bulkheads.

In this presentation we’ll examine how to leverage two popular libraries from Netflix, Hystrix and RxJava, to create reactive and fault tolerant systems.

Understand Java from a functional programming point of view. This part covers the basics of lambdas and streams, emphasizing functional programming by transforming collections using the stream approach.

Also includes method references and static and default methods in interfaces.

Functional features in Java, including parallel streams, the java.util.function package, the Optional data type, and reduction operations.

The talk also covers the new date and time package based on Joda time, as well as collectors and implementing the Collector interface.

Java SE 8 introduces many new features that can simplify your code. Using streams, lambdas, and the new Optional type all change the way we write Java. In this presentation, we'll work through a series of examples that show how to rewrite existing code from Java 7 or earlier using the new Java 8 approach.

Examples will include replacing anonymous inner classes with lambdas, switching from iterating over collections into transforming streams, using immutables wherever possible, lazy evaluation, and more.

You don't need Node.js or MongoDB to build “full-stack” solutions, but they sure help! This stack is popular for its scalability, its promise of developer productivity, and the capability to develop all components with a single programming language. Not all use cases are a great fit for JavaScript on the server. But love it or hate it, there are valuable lessons and use cases here for all developers.

We'll examine a complete multiuser end-to-end app using HTML5, CSS, and JavaScript. We'll connect it to a simple Node.js instance using WebSocket. We'll wire up a simple document-oriented persistence layer with MongoDB. And we'll do it all using mostly-vanilla JavaScript to illustrate concepts that don't depend on particular frameworks.

You'll leave this session convinced that full-stack JavaScript has “teeth”, and that it's not all just hype. And whether you intend to use JavaScript, Java, Ruby, or a mix of various frameworks on the server, the architecture of a dynamic HTML5 app will be made transparent and straightforward.

You don't need massive frameworks to build mobile apps responsive to touch events, that contain fluid animations, or that are easily deployed to app stores. All you really need is a solid grasp of the JavaScript, CSS3, and HTML5 features and APIs that enable a compelling experience.

In this session, I will show some examples of mobile apps built with HTML5 that offer instantaneous handling of touch events such as pan gestures. I'll demonstrate best practices using CSS3 transitions to implement card and panel design patterns typical of mobile user interfaces. And I'll show just how easy it is to extend the device features available to HTML5 using Cordova, packaging a mobile app for app store deployment.

HTML5 hasn't fundamentally changed the way we build web applications — JavaScript frameworks did that. Not so with Web Components! Web Components are the most important update to HTML and the Document Object Model in recent years. They have a major impact on client-side architecture, on framework selection, and on distribution and reuse of code.

In this session, I'll explain to you the four Web Components standards, their current state, and why you should care. I'll give several examples of complex applications built in Web Components, and running in all modern browsers — including a rich mobile game.

By the end of this conference you will have learned many new tools and technologies. The easy part is done, now for the hard part: getting the rest of the teamand managementon board with the new ideas. Easier said than done.

Whether you want to effect culture change in your organization, lead the transition toward a new technology, or are simply asking for better tools; you must first understand that having a “good idea” is just the beginning. How can you dramatically increase your odds of success?

You will learn 12 concrete strategies to build consensus within your team as well as 6 technique to dramatically increase the odds that the other person will say “Yes” to your requests.

As a professional mentalist, Michael has been a student of psychology, human behavior and the principles of influence for nearly two decades. There are universal principles of influence that neccessary to both understand and leverage if you want to be more effective leader of change in your organization.

In this session we discuss strategies for getting your team on board as well as when/how to approach management within the department and also higherup in the organization.

It happens to us all; there are simply days where it seems impossible to get anything done. This session focuses on techniques and tips to get into the zone, stay in the zone and to protect your productivity, even in disruptive environments.

Rather than focusing on any one productivity methodology (e.g. GTD) This talk analyzes the internal and external factors that affect our productivity and offers broader strategies to get back on track.

Unlock your latent photographic memory. In this session you'll learn failsafe techniques and systems that allow you to never forget names, appointments, or numbers. In the process you'll be more effective and imaginative at work; improve reading speed and comprehension, and shorten study times.

An improved memory will change your life, literally. In the session we will describe in detail several memory techniques that, with a little practice, will have you remembering virtually anything you want.

We all have an innate sense of what's possible. Not only is this how magicians fool you, but it might also be what's holding you back.

In this session Michael Carducci shares how he applied lessons learned in his career as a professional magician to his “day-job” as a software engineer.

Magicians have a simple process for creating new material; think of the most impossible thing you can imagine, the engineer a way to make it possible. Michael has been engineering solutions to “impossible” problems for nearly 20 years and this has given him a unique perspective on dealing with challenges in all aspects of his life.

This talk combines illusion, anecdotes and real-world examples to help identify and overcome your mental obstacles.

When the opportunity arises for development of a new application, or the modernization of an old one, the architect is faced with a myriad of often conflicting choices. There are so many choices there's a significant risks of falling into analysis paralysis or simply defaulting to safe solutions. (“No one ever got fired for choosing IBM.“) On the other side of risk adversity lies RDD - Resume Driven Design - where all the newest, riskiest technologies are thrown into the mix just so the app development will be hot and sexy.

This session explores some architectural trade-offs and lays out a road map for successfully architecting a new project, with key emphasis on targeting accidental complexity and launching the project on the right course while preserving plenty of alternatives.

Suppose you've just been assigned to be the architect on a new development project. The new CTO has no love for the status quo process the organization has been (not) delivering software. (Not delivering software is exactly why there is a new CTO.)

You've been emailed half a dozen Powerpoints outlining the business needs. It's clear the business stakeholders care about two things: Time-to-market and functional effectiveness. Otherwise, they don't care about any of the technical gobbledygook the developers usually use when discussing projects. The developers love all the new languages and technologies and will hate implementing some boring CRUD app for the 99th time.

After years of yearning for a greenfield project, now's your chance to shine - or fall on your keister. Where to start? In this session, we'll develop an architectural road map for successfully bootstrapping your new project without getting yourself boxed into a bad place.

“There's a new JS framework every week! There's a new JavaScript feature every week! There's a new HTML5 feature every week! We are losing our minds OMG@#$HELPUS!”

Settle down everybody. Shiny new frameworks distract you from the stability offered by the web platform: ES6 is the first major update to JavaScript since 2009, and HTML5 was 18 years in the making! More importantly, few of these innovations significantly change the architecture of web applications — we owe browser innovation and frameworks for that. But since the browser evolved in to a full-blown application runtime, we now need solid front-end architecture, and front-end architects. It's not just about JavaScript, it's about the entire browser platform. And you can't pick frameworks to simplify that platform until you understand its underpinnings.

In this workshop, we will dissect the components of a modern web client into three buckets:

1. Networking: How does data get to and from the client? We will discuss the various underlying APIs and libraries for client-server communication.
2. Rendering: How does the user interface get created and painted? We'll look at the HTML5 APIs for manipulating the DOM, and explain how various frameworks including AngularJS, React, and Polymer regard and manipulate the DOM.
3. Distribution & Maintenance: How does the resulting app get distributed and updated, either on the web or to app stores?

I'll lay the foundations to simplify the complex world of front-end tools, frameworks, and architecture. I'll share patterns to help you manage the complexity of front-end development and back-end integration for modern web clients. And I'll convince you to never again complain about how fast the world of front-end technologies is moving.

Regular Expressions are an undervalued, underutilized tool in the developer toolbox. Few programming technologies have stood a comparable test of time for their capacity to improve developer productivity, to shortcut complex tasks, to reduce dependency on various libraries, and to encourage code reuse. They also help to teach patterns and improve pattern recognition, not only for code, but for programmers themselves. Competency with regexes will make you a better programmer, regardless of your choice of language or platforms. And it will impress your peers, too!

This workshop will teach you the fundamentals of writing, debugging, and testing PCREs (Perl-compatible Regular Expressions) in multiple programming languages. With hands-on examples we will cover regex syntax, metacharacters, assertions, grouping, quantifiers, greed, capturing, balanced matches, and replacing. We'll compose regexes from scratch to parse some common string formats such as URLs, email addresses, and even JSON. Given enough time, we'll even learn look-around assertions, and examine some creating uses of regexes in the field of natural language processing.

We've got some seriously big problems in our industry. Under constant business pressure, our organization's drive one project after another into the ground. Once the chaos and fire-fighting finally gets out of control, we rewrite our software… again. How long are we going to wait for somebody else to solve this problem?!

It's about time we took responsibility. OpenDX is a strategy to kick this problem's ass. How? By measuring the pain, and putting the ridiculous costs and risks on center stage for everyone to see, then working together to figure it out.

In this talk, we'll get into the weeds of #OpenDX, a specification for data collection in software development for universally measuring the “pain” or “friction” in developer experience.

• What type of tools do we use?
• What type of analysis can we do?
• What type of patterns can we see?

Visibility changes everything. Once we can measure the pain, explain the costs and risks, and get managers and developers all pulling the same direction, suddenly we can start optimizing our organization's with a data-driven feedback loop.

OpenDX is about making healthy software projects the new norm in our industry. Status quo – You better watch out.

This is my story of lessons learned on how to stop the crushing effects of business pressure… I was team lead with full control of our green-field project. After a year, we had continuous delivery, a beautiful clean code base, and worked directly with our customers to design the features. Then our company split in two, we were moved under different management, and I watched my project get crushed.

As a consultant, I saw the same pattern of relentless business pressure everywhere, driving one project after another into the ground. I made it my mission to help the development teams solve this problem. This is my story of lessons learned on how to transform an organization from the bottom up. I'll show you how to lead the way.

The crushing business pressure is caused by a broken feedback loop that's baked into the organization's design. In this presentation, I'll show you how to fix the broken feedback loop. Learn how to:

• Gather evidence of developer productivity loss
• Identify the key organizational changes required for success
• Make the case to management for improvement
• Partner with your manager for long-term success

If the system is broken, we need to fix the system. You can change the system by making the decision to lead.

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.

No matter the techniques used to make enterprise solutions Highly Available (HA), failure is inevitable at some point. Resiliency refers to how quickly a system reacts to and recovers from such failures. This presentation discusses various architectural resiliency techniques and patterns that help increase Mean Time to Failure (MTTF), also known as Fault Tolerance, and decrease Mean Time to Recovery (MTTR).

Failure of Highly Available (HA) enterprise solutions is inevitable. However, in today's highly interconnected global economy, uptime is crucial. The impact of downtime is amplified when considering Service Level Agreement (SLA) penalties and lost revenue. Even more damaging is the harm to an organization's reputation as frustrated customers express their grievances on social media. Resiliency, often overlooked in favor of availability, is essential.

Using the Microservices Architectural Style to incrementally adopt an Event-driven Architecture (EDA) lowers up-front costs while decreasing time-to-market. EDA extracts value from existing occurrences, limiting invasive refactoring or disrupting existing application development efforts. Implementing Event-driven Microservices yields intelligence, scalable, extensible, reactive endpoints.

This session will cover the fundamentals, patterns, techniques and pitfalls of Event-driven Microservices with several demos leveraging Spring-Boot, Camel, ActiveMQ and Docker.

While rummaging through some books the other day, I came across my copy of The Pragmatic Programmer. Flipping to the copyright page, I realized that it had been 16 years since its publication. Many of our careers have been deeply affected by reading and considering the many nuggets of wisdom contained in this book, and it is near the top of multiple recommended reading lists.

In this presentation, we’ll revisit this book, and we’ll also consider what we’ve learned since its publication - what would we change? And what remains timeless?

Over the past year I’ve had the pleasure of wearing the hat of “product manager” for the Spring Cloud Services team at Pivotal, operating using a distributed variant of the Pivotal Labs process. Along the way I’ve learned many valuable lessons that I hope you’ll be able to apply to your product development efforts.

In this presentation we’ll examine the relationship of product management to engineering and to your customer, and how you can be an effective broker between the two groups.

Visibility is one of the primary characteristics of applications that aren’t just coded well, but run well in production. We need visibility to understand:

• how our system performs
• how our system misbehaves
• how our system fails
• how our users interact with our system
• what’s providing value to users and what’s not
• and more!

In this talk we’ll look at the three disciplines of monitoring, metrics, and logging, and see how properly used, they can dramatically increase our system’s inherent visibility.

Topics will include:

• what metrics should we collect?
• how should we expose those metrics?
• can frameworks help?
• what should we monitor?
• monitoring components vs. systems
• building dashboards
• the art of logging
• log aggregation and analysis
• tools, tools, tools, tools!

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.

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.

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.

How do we define identity in a distributed software system? How do we manage it securely? How do we make identity assertions and verify those claims?

Technologies don't magically become solutions. They are used within domain, design and deployment contexts. This talk will focus on the singular notion of Identity and how it cross-cuts the distributed systems we are building.

We will focus on a variety of technologies and standards that help us make, identify, claim and verify identities.

Authenticated Identities are the first step to establish Privilege. Most systems fail to have sufficiently, deeply entrenched notion of how to apply and minimize privilege to avoid data and systems from being abused.

Technologies don't magically become solutions. They are used within domain, design and deployment contexts. This talk will focus on the singular notion of Privilege and how it cross-cuts the distributed systems we are building.

This talk will focus on the Valet Key problem and how to avoid it. We will visit various standards and technologies that help us strengthen our security profiles by reducing our dependence on open-ended and unfettered access to our systems and data.

Data integration costs are well beyond what they should be for such a crucial business function. The good news is that they needn't be. By relying on integration-friendly standards and technologies that were designed to support sharing information, we can reduce these costs while increasing our business capabilities.

Technologies don't magically become solutions. They are used within domain, design and deployment contexts. This talk will focus on the singular notion of Integration and how it cross-cuts the distributed systems we are building.

We will look at how the REST Architectural style leads us to integration-friendly standards such as RDF, Linked Data, SPARQL and JSON-LD. These technologies are useful both within our firewalls and with third party partners.

Our biological world changes gracefully. Our information world changes much less so. How can we embrace the inevitable technological, procedural and schematic flux that we know is going to visit upon us at some point?

Technologies don't magically become solutions. They are used within domain, design and deployment contexts. This talk will focus on the singular notion of Evolution and how it cross-cuts the distributed systems we are building.

We will focus on strategies from the Web standards space to define information systems that embrace change and handle it with relative ease.

This will include strategies for dealing with changing technologies, changing schemas and more.

Information conveys value as it travels around our systems, resting for a time in our data stores. The value we get out of it is sometimes matched by the value others would get from it as well. We need mechanisms to protect sensitive information from prying eyes and control with whom we share it.

Technologies don't magically become solutions. They are used within domain, design and deployment contexts. This talk will focus on the singular notion of Secrecy and how it cross-cuts the distributed systems we are building.

This talk will focus on strategies from the world of encryption to keep secrets secret as we produce, store and transfer information in distributed systems. A successful strategy for doing so will rely on notions of Identity and a strong Privilege model, but we will mostly focus on specific building blocks upon which we maintain Privacy and Confidentiality.

We will also address the forces that undermine our ability to trust encryption such as bugs, design flaws and those who wish to actively undermine our need to maintain Secrecy.

Docker and containers are getting a lot of attention these days but what do they mean for devs? How do they fit into DevOps and continuous delivery movements? Where do these tools fit into cloud computing? During this hands-on session we will learn how to install and configure Docker, build images and run containers in a local development environment. But we will also explore using them in a continuous deployment environment by deploying them to on premise as well as cloud services such as AWS.

QA. We all know we need it, but quality takes time. How do we squeeze it into two-week sprints? Is a story really done if we haven’t finished QA? Do your Dev teams throw “code over the wall” to be tested in the next sprint? Or are your testers expected to test all your code in the last three Days of your Sprint? These are anti-patterns we see all the time in the Large Enterprise. In this presentation we will discuss how QA is handled - and mishandled when an Enterprises “adopt” Scrum. We will conclude with the best approaches to delivering potentially shippable code, in a quickly changing business world. This presentation will assume a basic understanding of agile principles.

In this presentation we will discuss how QA is handled - and mishandled. We will conclude with the best approaches to delivering production ready code in a lean, agile world. This presentation will assume a basic understanding of agile principles. This talk is not technical in nature. It is intended for those struggling with the transition from traditional QA enterprise teams - silos, testers report to a separate management structure - to QA in an Agile environment. We will discuss QA anti-patterns and how agile addresses them.

User Stories. We have all heard of them, but do we truly understand them? Aren’t they just use cases repackaged and marketed as “agile”? Are they just a euphemism for “requirements”?

In this presentation, we will take a deep dive into User Stories: their purpose and how to develop them. We will take a look at user stories together and dig into the really tough topics such as how to handle non-functional requirements in an agile world. Next we will discuss sizing and story point estimation and then estimate the stories we have created while discussing estimating software in general and estimation in agile in particular. Finally we will develop Acceptance Criteria and discuss what the definition of done really means to you, your team, and your product owner. You will leave with the tools you need to help your team understand and develop real user stories and establish a stable velocity.

There is a fifth dimension beyond that which is known to us. It is a dimension as vast as space and as timeless as infinity. It is the middle ground of non-commitment between light and shadow, between science and superstition, agile and waterfall, and it lies between the pit of your fear of Big Up Front Design and your Project Manager’s desperate need for “dates” and “estimates”. This is the methodology of stagnation. It is an area which we call “The Scrummerfall Zone”… NOTE: This presentation is for those who have a solid understanding of agile principles, but are struggling with the transition to agile. There will be a lot of discussion during and after the presentation. Be prepared to talk.

Have you been sucked into a twilight zone like development process in which agile terms are slapped on to waterfall practices while management triumphantly declares your efforts “Agile”? In this presentation we will discuss some of the things that happen when waterfall meets agile in the large enterprise and the confusion and chaos that ensues. We’ll end with a discussion on productive ways to challenge the acceptance of scrummerfall and help bring your organization back from “The Scrummerfall Zone”.
Notice the emphasis on discussion. This will be an interactive session with approximately 60 minutes of presentation and 30 minutes reserved for discussion and questions. Be prepared to participate and ask question.

In this session we'll explore implementation of some Enterprise Integration Patterns using Apache Camel with Java, Groovy and Spring.

Camel makes defining Message routes easy and supports configuring dozens of endpoint types, including internal direct web service endpoints, Amazon Web Services (AWS) endpoints, file and FTP end points, JMS endpoints and many more, It also makes mocking and testing endpoints easy to reduce test fragility.

We'll start with a brief introduction to Enterprise Integration Patterns and messaging, then build up increasingly complex routes to a variety of endpoints.

We'll then explore methods for working with messages during the routing. We'll combine multiple messages, split messages into multiple parts, and transform messages from one form to another.

We'll also explore Camel's facilities for testing of routes and processors.

Reactive is a the latest buzzword to consume our industry. This presentation distills and defines reactive systems, describe the difference between reactive architecture vs. reactive programming, describe common patterns, and demos the popular reactive JVM technologies like RXJava, and Akka.

Introduction to reactive gets in deep on a discussion of patterns: Source, Sink, Back Pressure, Reactive Pull/Push including a Light introduction to actors using Akka, ReactiveX using RXJava and Reactive Streams in RXJava and Akka. We also will showcase the differences between ReactiveX and Akka.

A set various tools to write reactive, concurrent, fault-tolerant applications and services using immutable data, asynchronous message passing using local and remote actors, software transactional memory, and supervised systems. This entire presentation is done in Java.

Akka is a set of various tools to write reactive, concurrent, fault-tolerant applications and services using immutable data, asynchronous 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, Spray, Slick, and the Scala programming language. This Akka presentation will cover Java style usage of Akka with actors, asynchronous message passing, supervision, and streams

Starting with JDK 5, we have had Futures, and they mostly went ignored. Now with concurrency and reactive technology in demand, it is essential that we understand what futures are, and how to handle them and make use of their power in asynchronous systems.

This presentation is a basic ground up introduction to Futures. We start with Futures and how they came packaged with JDK 5. We take a look at Executors, how to create a thread pool, which pool you should choose. How to model Futures in the JDK and show the difference for awaiting the answer and taking on the answer asynchronously. We also take a look at what a Promise is and when to use one. We then invest time taking a look at Guava's callback solution. Then we finally look at the handling of futures in both Scala and Clojure.

ReactiveX is a set of Reactive Extensions developed by Netflix, and is developed for various programming languages, like Java, Scala, and Clojure. ReactiveX overhauls the observable design pattern to achieve reactive goals. This presentation will solely focus on the Java version of ReactiveX, RXJava.

RXJava is combining the Observer Pattern with Functional Programming to compose complex asynchronous reactive systems. This presentation will also give an overview on RXJava concepts like Source, Sink, BackPressure and Reactive Pull and Push.

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

Finagle is a Remote Procedure Call (RPC) System offering from Twitter. Built for high-concurrency and configurations, this network stack system is highly functional, and built on Futures to build asynchonous solutions.

This presentation we discuss building our own server and clients using Finagle, using filters to customize our calls, and using a wide array of tools available to clients.

Take control of your knowledge portfolio and be in demand! Your command of the top JVM languages; Java 8, Groovy, Scala, JRuby, and Clojure; will set you apart from the rest. This presentation will introduce each of these languages, highlight common ground, and show some stark differences.

This presentation will cover:

• How to install each of the JVM languages
• Describe the “functionality” of each of the languages
• Expressiveness vs. Terseness of each language
• How each language handles mutability
• How each language handles concurrency
• Amazing tricks of each language
• Comparison of language typing
• Comparison and contrast of language performance
• Each language's killer app
• Analysis of the language culture and where to get help?
• Tips on how to start learning and keep learning with a busy schedule

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

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

You've heard the old adage “It's not what you know it's who you know.” The focus of this session is divided between ways to better connect with everyone you meet as well as ways to grow your network, help and influence people and ultimately build long-term relationships and build your reputation.

Networking isn't about selling nor it isn't about “taking.” Done properly it benefits everyone. Among the benefits are strengthening relationships; getting new perspectives and ideas; building a reputation of being knowledgable, reliable and supportive; having access to opportunities and more!

Being a professional software engineer, it's easy to fall into the belief that one's role in a company is to write code.
Another perspective might be that one's role is to solve problems for the business and that writing code is merely one of several tools available to help solve those problems.

There are numerous problem-solving “anti-patterns” that are rampant in the industry today. “Forewarned is forearmed” as they say. In addition to highlighting these “anti-patterns” with real-life examples and the (sometimes) disastrous consequences, Michael asks some of the difficult questions about our true motivations for our decisions and how our decisions can either positively or negatively affect our team and our organization.

Whether your goals are higher concurrency, lower latency or high availability; there are proven techniques and strategies you can implement. Each requires careful consideration and comes with it's own challenges.

In this session we'll examine several architectures for running MySQL at scale and will be building each of the architectures live and hands-on.

Concourse (http://concourse.ci/) is a CI system composed of simple tools and ideas. Concourse can express entire pipelines, integrating with arbitrary resources, or it can be used to execute one-off tasks, either locally or in another CI system. Concourse attempts to reduce the risk of adoption by encouraging practices that keep your project loosely coupled to the details of your continuous integration infrastructure.

Concourse optimizes around the following principles:

• Simplicity
• Usability
• Build Isolation
• Scalable, reproducible deployments
• Flexibility
• Local iteration

During this session we'll learn the simple key concepts from which Concourse pipelines are constructed. We'll understand how to deploy a local Concourse cluster using Vagrant as well as a scalable Concourse cluster to your cloud of choice using Cloud Foundry BOSH. Finally, we'll look at basic and advanced examples of pipelines for Java projects.

Microservices are all the rage. But this isn’t a session on microservices. It’s a session on modularity. At the end of the day, microservices are just one way to the increase modularity of our software system. But there are others.

In this session we’ll refactor a monolith using patterns of modular architecture. In the end, you’ll see how the underlying set of principles used to modularize the monolith are virtually identical to the benefits of a microservice architecture, albeit manifest in a different way. Once modularized, you’ll also be amazed at how much architectural agility we have in our ability to now shift between different approaches to modularity, including microservices.

Microservice architecture is a modern architectural approach that focuses on breaking apart the monolith and building modular services. But the framework we use has a tremendous impact on how we build and deploy services. A new type of framework has emerged that provides a lightweight stack for building microservices.

In this session, we will explore some modern Java micro frameworks for building microservices. Example frameworks you may see include Dropwizard, Spark, Ninja, RestExpress, Play, Restlet, and RestX.

Traditional approaches to software architecture are broken. Attempts to define the architectural vision for a system early in the development lifecycle do not work. In today’s volatile technology and business climate, big architecture up front is not sustainable. In this session, we will explore several principles that help us create more flexible and adaptable software systems. But first, we’ll expose the true essence of what’s meant when we say “architectural agility.”

What’s the goal of architecture? To serve as a blueprint of the system that everyone understands? Possess the flexibility to evolve as new requirements emerge? To satisfy the architectural qualities, including performance, security, availability, reliability, and scalability? Yes. Yes. Yes. At the heart of these three questions are the three pillars of architecture - social, process, and structure. But how do we create software architectures that achieves all of these goals? And how do we ensure no disconnect occurs between developers responsible for implementation and architects responsible for the vision? In this session, we’ll explore several principles to increase architectural agility and provide some actionable advice that will help you get started immediately.

Much is said about the decentralized governance of and local autonomy given to “two pizza teams” build microservices. But how do you organize teams to effectively collaborate to build the eventual composite system?

In this presentation we’ll examine how to apply the Tracer Bullet Development methodology described in Ship It! to effectively construct distributed systems composed of microservices.

A number of developers and organizations are beginning to make use of Java 8. With anything that's new, we often learn it the hard way.

By stepping back and taking a look at programming style as idioms, we can quickly gravitate towards better coding style and also avoid some common traps that we often get drawn towards.

Sure, Java 8 has lambdas and streams. However, the JDK has gone through significant makeover to make good use of lambdas and streams. Furthermore, some of the new functional interfaces have far more than abstract methods.

In this presentation we will look beyond lambdas and streams, we will take a look at some of the fun filled, useful members of the JDK that will help us make better use of lambdas and streams.

What's in Java 9 and, more important, how does that impact us?

In this presentation we will take a look at the major features that are likely to make in to Java 9, discuss the benefits of each one of them using practical hands on examples.

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.

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.

We all have seen our share of bad code and some really good code as well. What are some of the common anti patterns that seem to be recurring over and over in code that sucks? By learning about these code smells and avoiding them, we can greatly help make our code better.

Come to this talk to learn about some common code smell and to share your experiences as well.

Are you getting optimal performance from your database? Do you secretly wonder if your my.cnf is even close to tuned for your hardware and workload?
In part 1 we embark on a deep dive into DB Design, Indexes, query tuning and configuration.

Learn the tools and techniques to make good design decisions to maximize performance. How to interpret query plans and benchmark and tune your queries. Leave with a deeper understanding of all the various configuration options available and how each affects performance.

On the NFJS tour, there are questions that seem to come up again and again. One common example is “How do we determine which new tools and technologies we should focus our energy on learning?” another is “How do we stop management from forcing us to cut corners on every release so we can create better and more maintainable code?” which, after awhile becomes “How can we best convince management we need to rewrite the business application?”

There is a single metaanswer to all these questions and many others.

It begins with the understanding that what we as engineers value, and what the business values are often very different (even if the ultimate goals are the same) By being able to understand these different perspectives it's possible to begin to frame our arguments around the needs and the wants of the business. This alone will make any engineer significantly more effective.

This session picks up from where “Stop writing code and start solving problems” stops discussing what is value, how do we align the values of the business with the needs and values of the engineer.
