John Esser of

Architecture for Continuous Delivery



The Git version control system and GitHub collaboration platform offer a myriad of innovative and classic development workflow options. The wide range of opinions about these on the Internet can make it challenging to nimbly make wise Git workflow decisions for your team's next project.

In this presentation, Matthew will provide a tour of successful workflow patterns harvested from 7 years of studying and working with open source projects, small and large scale businesses, and governmental agencies employing everything from waterfall to fully agile processes. Flows will feature live demonstrations of the supporting Git and GitHub commands.

A little guidance can go a long way in helping you navigate the new world of distributed version control, and this talk will help you make informed choices of the Git features you'll use, the branching patterns you'll leverage, and the way you will integrate your chosen pattern with your team's development practices.

Matthew McCullough works for GitHub, Inc. and trains audiences around the world on the most effective use of the Git version control system and GitHub collaboration platform. In supplement to travel-based teaching, he writes books and records videos for O'Reilly and Manning on the topics of delivering technical presentations, the use of modern build and continuous integration tools, and version control industry best practices.


Architecture for Continuous Delivery is the leading online family history website, with more than 2 million subscribers, many petabytes of genealogical records, and more than 160 services. As the subscriber base grew and Ancestry began to expand its customer base the need to innovate more rapidly became paramount and a focus on enabling continuous delivery emerged.Attempting to do continuous delivery not only requires changes in culture, technical practices, and infrastructure, but also requires a system architecture that supports it. The challenge at Ancestry was to migrate from a monolithic, coupled stack to a more service-oriented one that allowed teams to deploy code independently to the website without extensive coordination.  Just like Ancestry, many companies that want to do continuous delivery find they can’t because their system architecture is the bottleneck.

This presentation will discuss’s transformation to a service-oriented architecture capable of supporting continuous delivery. We will discuss the architectural standards that guided the transformation and how we quantified architectural debt to determine which parts of the stack needed rework. Lastly, we will show how continuous delivery works in the context of the architecture

John Esser is currently the Director of Engineering Productivity and Agile Development at His team’s mission is to accelerate engineering’s ability to deliver value to the customer. He is the architect of Ancestry’s transformation to Agile development and continuous delivery. John has more than 25 years software development experience working for such companies as IBM, Corel, Callware Technologies, and Control4. His spare time is gobbled up by his beautiful wife, four teenage sons, reading lots of books, and fly-fishing for trout on the Provo River.

Write Java Apps Faster Using SaaS Developer Environments by Codenvy

The Java community is filled with terrific solutions for enabling development of apps.  Every Java developer has their choice of tools and the openness of the platform makes it accessible to anyone and extensible by everyone.

But why then, is 99% of all development still done locally?  While sales, marketing, customer service, support, finance, and infrastructure has steadily moved to the cloud over the past decade, Java development remains rooted on the desktop.  Will it always be this way?

In this session, we will discuss the evolution of remote development of Java applications and the emergence of SaaS Developer Environments.  Often times called a cloud IDE, a SaaS environment can eliminate configuration, increase collaboration, and alleviate management concerns around consistency, compliance, and velocity.   In essence, SaaS developer environments can make agile, more agile. 

The presenter will be from Codenvy, a SaaS developer environment that is built with Java.

Building Web App UI with Vaadin by Dr. Joonas Lehtinen

Vaadin is a popular web framework that combines web and Java platforms in an unique way. Writing an application that lazily loads large amounts of data from the server, includes drag-and-drop, keyboard navigation and compelling visualizations should not require writing any HTML, JavaScript or designing a REST API. All you need to do is write a component based UI in Java or any other JVM based language.

The framework is based on a server centric development model that provides the best productivity, but it also supports client-side development with the built-in GWT Java to JavaScript compiler. It also allows you to go through the abstractions and write JavaScript directly. The looks of the application are customized with CSS and SCSS as the end results is just plain HTML5.

The presentation gives an overview to Vaadin and explains how it works. We'll also discuss on what are the latest new features of Vaadin and how the roadmap looks. The session should give you everything you need to get started building your own apps with the free Apache-licensed Vaadin.  your system highly available.

Dr. Joonas Lehtinen is the founder of Vaadin project, a Java-based framework for building awesome web UI easily in Java. He is the founder and CEO of the company behind the Vaadin framework and leads a team of 80 engineers who are mostly working in European timezones. While not at a hangout to 10 timezones away from Vaadin's Silicon Valley offices, Joonas keeps failing in finding a way to get rid of his Finnish accent.

Venkat Subramaniam

Lambda Expressions

Programming with Lambda Expressions in Java

Now that Java is supporting lambda expressions, it's time to hone our skills to make use of them. Lambda expressions can help create concise code, however, it takes more than learning the syntax to put them to good use. In this presentation we will learn the idiomatic use of lambda expressions, explore the ways in which we can use them to solve common tasks, and look into libraries and APIs that make use of them in Java.

Parallel continues their hiring workshop


Enterprise Mobile Strategy by Kamal Thota

The mobile industry is evolving rapidly. More people are accessing services from a mobile device than ever before. For an enterprise, this can mean that a growing number of customers, business partners, and even employees now expect to access services on a mobile channel. Organizations must start developing more mobile applications targeting this segment of markets and audiences. This opens new opportunities for the business but also presents new challenges, both in terms of business processes, marketing, and especially information technology (IT) infrastructure.

In this session, we will share the details on the mobile strategy and application platform development architecture at Intermountain Healthcare. This will help other organizations to understand our approach of developing a mobile portal/container using HTML5, hybrid, and native applications. We will briefly look at some of the development frameworks, libraries (plugins), and tools like Cordova, Sencha, etc. needed for complete mobile application development, deployment, and management within a business.

Effective SOA: Lessons from Amazon, Google, and Lucidchart by Derrick Isaacson

It has been observed that "A distributed system is at best a necessary evil, evil because of the extra complexity." Multiple nodes computing on inconsistent state with regular communication failures present entirely different challenges than those computer science students face in the classroom writing DFS algorithms. The past 30 years have seen some interesting theories and architectures to deal with these complexities in what we now call "cloud computing". Some researchers worked on "distributed memory" and others built "remote procedure calls". More commercially successful architectures of late have popularized ideas like the CAP theorem, distributed caches, and REST.

Using examples from companies like Amazon and Google this presentation walks through some practical tips to evolve your service-oriented architecture. Google's Chubby service demonstrates how you can take advantage of CAP's "best effort availability" options and Amazon's "best effort consistency" services show the other end of the spectrum. Practical lessons learned from Lucidchart's forays into SOA share insight through quantitative analyses on how to make your system highly available.

Derrick Isaacson is the Director of Engineering for Lucid Software Inc ( He has a BS in EE from BYU and an MS in CS from Stanford. He's developed big services at Amazon, web platforms for Microsoft, and graphical apps at Lucidchart. Derrick has two patent applications at Microsoft and Domo. For fun he cycles, backpacks, and takes his son out in their truck.

Parallel continues their hiring workshop, this month featuring Interview Preparation


How to effectively utilize the Java testing tool chain to successfully execute tests on Sauce Labs

The Java development ecosystem has always been a first class citizen in the functional browser testing space. Two problems most commonly faced are long test suite execution times as well as platform coverage and the infrastructure requirements associate with it. Even more so in a continuous integration setting.

In this session we will walk through an end to end showcase on how to leverage the Sauce Labs cloud testing platform to execute tests efficiently. We’ll take advantage of well established and familiar tools, like JUnit, Eclipse and Maven to illustrate best practices in the area of functional browser testing.


Three ingredients that go well together: JavaScript Unit Tests + Karma + Sauce Labs

Fueled by the possibilities of HTML5 a trend to move more and more application logic over to the frontend enjoys increasing popularity. Efforts to bring more structure into code bases have create frameworks like Backbone.js, Angular.js and Ember.js amongst others.

At the same time, test frameworks (e.g. Mocha, Jasmine, QUnit) have been created to satisfy the need to create and execute tests in the same environment that JavaScript code actually runs -- the browser.

In this session we’ll focus on how Sauce Labs can help JavaScript unit testers leverage the variety of browser platforms provided by their cloud platform. We’ll showcase how Karma, a smart test runner for JavaScript unit tests, and Sauce Labs will work together to make developers’ lives “bug free” and easier.

IntelliJ Tips and Tricks for Web Development

John Lindquist will speak about the tips and tricks he's picked up over the years of working with IntelliJ and show off some of the new features of IntelliJ 13. He'll also talk about of the future focus on JetBrains and what we have planned going forward.


Code-driven introduction to the Java EE 7 Platform

The Java EE 7 platform focuses on Productivity and HTML5. JAX-RS 2 adds a new Client API to invoke the RESTful endpoints, allows asynchronous client/server, and server-side content negotiation. JMS 2 is undergoing a complete overhaul to align with improvements in the Java language. Long awaited Batch Processing API and Concurrency are now added to build applications using capabilities of the platform itself. Together these APIs allow you to be more productive by simplifying enterprise development.

WebSocket attempts to solve the issues and limitations of HTTP for real-time communication. A new API is added to build WebSocket driven applications. Processing JSON structures is inherent in any HTML5 applications and a new API to parse and generate JSON is being added to the platform. JavaServer Faces will add support for creating reusable flows and HTML5-friendly markup. There are several other improvements in this latest version of the platform.

This code-driven talk will provide an introduction to the Java EE 7 platform. Don't miss out on this session to learn all about how to leverage the new and exciting standards in building your next enterprise application.

Parallel HR continues their popular hiring workshop.


Restful Services with Jersey

Ever wondered how to get started with REST using Jersey? What about some of the API considerations that should go into your architecture? In this presentation we are going to show how to get up and running, what to consider in your API, and how to test your RESTful services in your application using plugins and other tools. Come with your questions too as we will have a Q/A session at the end.

Bryan Hansen is the Java Practice Manager and an Architect for Software Technology Group ( He has been programming in Java since 1997 and been building Enterprise Systems for over 15 years in public, private, and non profit organizations.


The Science and Art of Backward Compatibility

One of the most common pitfalls developers face on larger projects is backward compatibility. This session shows how to ensure that new versions of a library do not break either source backward compatibility or binary backward compatibility. After reviewing what each type of compatibility means and why it is important, the presentation covers requirements for each type, along with ways to meet these requirements. The main areas of interest are API evolution and evolving classes in a way that does not break “wire compatibility” for Java serialization. The presentation also covers techniques for verifying backward compatibility through regression tests.

Ian Robertson has 13 years of experience with Java, and is the author/coauthor of several open source projects, including Jamon, a Java templating language, and Pojomatic, a library for easily generating equals and hashcode implementations from simple annotations. He holds a Ph.D. in Mathematics from the University of Chicago.

Ceylon 1.0 was released this week, it's a highly understandable object-oriented language with static typing. The language features:

  • an emphasis upon readability and a strong bias toward omission or elimination of potentially-harmful constructs,
  • an extremely powerful type system combining subtype and parametric polymorphism with declaration-site variance, including first-class union and intersection types, and using principal types for local type inference and flow-dependent typing,
  • a unique treatment of function and tuple types, enabling powerful abstractions,
  • first-class constructs for defining modules and dependencies between modules,
  • a very flexible syntax including comprehensions and support for expressing tree-like structures, and
  • fully-reified generic types, on both the JVM and JavaScript virtual machines, and a unique typesafe metamodel.

Gavin King leads the Ceylon project at Red Hat. Gavin is the creator of Hibernate, a popular object/relational persistence solution for Java, and the Seam Framework, an application framework for enterprise Java
