The Fundamentals of Enterprise HTML5 Development

Developers are facing a new era of development with HTML5 for both mobile and desktop environments. It was once laughable to put mobile focused development ahead of the desktop, but those days are over. Whether you’re focused only on mobile, desktop, or both, there are a few critical questions which must be answered:

  • Which platforms and browsers should I support?
  • Which HTML5 related specifications are available on those platforms?
  • How do I integrate existing enterprise services?
  • How do I test my app?

Wesley will attempt to answer these questions with the latest market data and live demos. Attendees will learn what it takes to build a scalable, enterprise, HTML5 based application for both desktop and mobile environments.

The slides are not available.

All about Caching.

I have talked to a lot of people about Ehcache over the years. What people find most valuable, and what stays with them, is the underlying caching theory - you can see the light bulb go on.

In this talk we will start with a performance problem and lead you through solving it with caching, discovering a long the way the problems of distributed caching and their solution. This will equip you with the tools to analyse a performance situation and to see whether a cache will help and what type of cache to apply.

Topics include:

  • Why caching works
  • Standalone cache performance and effectiveness
  • Tiered Cache Design
  • N * Problem
  • Cache Cluster topologies
  • Cache Coherency Problem
  • CAP and PACELC constraints
  • Overcoming Java’s limitations with BigMemory

This session will be relevant to both technical audiences wanting to learn more about Java SE and the OpenJDK community structure.

Nothing matters more than coding fast

This is not a talk about speed coding, or writing thousands of lines of crappy code in a weekend.  This is a talk for software craftsman who test drive clean code, but who also have a nagging feeling:  “Man, I know I could be doing this faster.”  We’re going to discuss everything from touch typing, to keyboard shortcuts, to faster pair programming techniques, to hardware, to build automation, to staying in the zone, to caffeine consumption, to ergonomics, to music and headphone selection, refactoring, language and framework selection, tech debt management, rapid prototyping, whiteboard design sessions, back of napkin mockups, guerilla tactics for getting in front of requirements and staying there, and what to do when you’re 30 lines down a stack trace and someone wants to tell you about something funny their kid did over the weekend.

Build Trust in Your Build to Deployment Flow!

Frequently deploying to production puts bigger pressure than before on DevOps to make sure the good, qualified application is provisioned with no mistakes.This session will explore some common pitfalls with traditional Continuous-Integration that increase risk, introduce manual input and human error, and generally make DevOps cringe before hitting the “deploy” button.

We will then demonstrate automation techniques that overcome these issues using popular tools, like Maven, Gradle, your CI server, custom scripts and a Binary Repository.
Whether you are building software for the cloud or in-house, this presentation will show you how to have completely automated production builds that release applications which are fully traceable, managed and ready to be provisioned with no fear!

Making Java Bearable with Guava

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

Radical NoSQL Scalability with Cassandra

Want to go deep on a popular NoSQL database? Cassandra is a scalable, highly available, column-oriented data store in use at Facebook, Twitter, Reddit, Rackspace, and other web-scale operations. It offers a compelling combination of a rich data model, a robust deployment track record, and a sound architecture, making it a good choice of NoSQL databases to study first.

In this session, we’ll talk about Cassandra’s data model, look at its query idioms, talk about how to deploy it, and look at use cases in which it is an appropriate data storage solution. We’ll study its origins in the Amazon Dynamo project and Google’s BigTable, and learn how its architecture helps us achieve the gold standard of scalability: horizontal scalability on commodity hardware. You’ll leave prepared to begin experimenting with Cassandra immediately and planning its adoption in your next project.

Per request, the presentation slides won’t be made available.

The Groovy Web: groovlets, Micro-frameworks, and Grails

Groovy has several ways to make web development easier. Groovlets are part of the language, are easy to use and deploy, and are the basis of larger frameworks like Gaelyk. Groovy also supports the new style of web development with micro-frameworks. One in particular is Ratpack, based on the Sinatra project in the Ruby world. Finally, there is Grails, the elegant combination of Groovy DSLs with Spring and Hibernate. This talk will demonstrate them all and discuss where each is useful and appropriate.

Java User Groups and the Java Community Process: a winning combination

The success of the Java language and platform depends on community support and participation. Java is developed through the Java Community Process, which is open to all members of the Java community. Recent changes to the process, introduced in JSR 348, make it even easier for developers to observe and to participate in the work of the JCP.

Even before these changes Java User Groups had begun to participate in the work of the JCP. Now that two JUGs (SouJava and the London Java Community) are represented on the JCP’s Executive Committee we are beginning to explore ways in which the energy, enthusiasm, and expertise of the JUG community can be harnessed to further advance the Java platforms.

Most developers understand the value of participating in open-source projects. This session will explain the benefits of participating in the JCP. We will explain how the JCP is is organized and how Java standards are developed. We will discuss the current state of the Java platforms, explain how the JCP is helping to evolve them, provide practical advice on how you can participate through your local Java User Group, and explain why participation is good for your career.

Bring your questions, your suggestions, and your concerns. We want to hear from you - the foundation of the Java community - and to explore new ideas for community participation.

Advanced JavaScript for Java Devs

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

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

Native Android Development with Spring Android

This session will provide an introductory overview of Android’s architecture and the layout of an Android project. When building Android apps, you may want to take advantage of a third party library, like Spring Android. You can do this through the use of various Maven plugins and tools for enabling dependency management in your Android project. We will walk through how to set up and configure an Android project using Maven. Many applications consume data from various web services, and we will discuss how the Spring Android project can help.

Spring Android provides an abstraction for consuming RESTful services and marshaling the requests and responses to JSON or XML. Lastly, Spring Android supports the use of Spring Social on Android, and we will discuss how Spring Social can help you connect your apps to OAuth protected services like Facebook and Twitter.

The Gradle Will Rock

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, repositories, and processes without being bound by its limitations. This talk will cover the basics of Gradle both through simple projects and by examining the build files for other open source projects. With major systems like Grails, Hibernate, and even the Spring Framework moving to Gradle, this is a technology worth taking the time to understand.

Migrating Enterprise Apps to the Cloud: from monolith to modular

The cloud movement is no longer just buzz and hype. Organizations are increasingly planning cloud-based deployments. For greenfield development, the path is relatively clear, but what about existing apps? The monolithic multi-tier architecture so common for enterprise apps is not the best fit for the cloud. For one thing, the presentation layer is typically moving to the client side. With cloud-based messaging and NoSQL datastore options, the data access and integration layers might require renovation as well. Meanwhile the significant investment that a business would most like to salvage is in the service layer sandwiched in the middle. In this session, we’ll explore this space while migrating a hypothetical application to run in the cloud. The starting point will be a fairly standard multi-tier Spring MVC application, and the end result will be a collection of services running in the cloud. We’ll discuss REST, JSON, NoSQL, messaging, polyglot development, and modular architectures designed to run in a dynamic always-on environment.

Git Going with Distributed Version Control

Many development shops have made the leap from RCS, Perforce, ClearCase, PVCS, CVS, BitKeeper or SourceSafe to the modern Subversion (SVN) version control system. But why not take the next massive stride in productivity and get on board with Git, a distributed version control system (DVCS). Jump ahead of the masses staying on Subversion, and increase your team’s productivity, debugging effectiveness, flexibility in cutting releases, and repository redundancy at $0 cost. Understand how distributed version control systems are game-changers and pick up the lingo that will become standard in the next few years.

In this talk, we discuss the team changes that liberate you from the central server, but still conform to the corporate expectation that there’s a central master repository. You’ll get a cheat sheet for Git, and a trail-map from someone who’s actually experienced the Subversion to Git transition.

Per request, the presentation slides won’t be made available.

Building CDI extensions using DeltaSpike

You’ve heard about the extensibility of Java EE 6, and heard about CDI (Contexts and Dependency Injection). You may have also looked at Seam 3 or MyFaces CODI. You’ve seen enough to pique your curiosity. This session will sate that curiosity and give you enough information to build great extensions for your application and business.

In this session, Jason Porter, Senior Software Engineer at Red Hat and Apache DeltaSpike contributor, will cover creating extensions in Java EE 6 and show how using Apache DeltaSpike will ease some of the work.

Joda Time and a Brief History of the World

JodaTime is Java Date/Time and Calendering done right. There are many problems with the original Date/Time API that came prepackaged in the early Java days. There are even more problems with the subsequent Calendar API.

One of the obvious issues is that Calendar is mutable and can unintentionally be changed. Another issue is that constructing Calendars in Java involves setting certain fields at certain times during coding, but not always getting the expected result. Joda Time repairs those issues and offers a robust and immutable date, time, and duration API. In Joda Time and a Brief History of the World, I provide a quick rundown of calendaring throughout the centuries, describe UTC, compare UTC to GMT, discuss how time is calculated, and then dive into Joda Time in every popular JVM language. The end result provides the audience with compelling proof that Joda Time should always be their Date Time API of choice.

RESTful Imaginarium

RESTful web services have become the preferred approach to synchronously integrating heterogeneous systems. The architectural style’s success is due in large part to its simplicity. Furthermore, REST is based on a small set of widely accepted standards, such as HTTP and XML and requires far fewer development steps, toolkits and execution engines than conventional SOAP web services.

This session covers the core concepts of REST and then walks through how to design and implement RESTful web services using three leading RESTful web service framewokrs, RESTlet, Spring MVC and NetKernel.

NoSQL Smackdown 2012

Alternative databases continue to establish their role in the technology stack of the future—and for many, the technology stack of the present. Making mature engineering decisions about when to adopt new products is not easy, and requires that we learn about them both from an abstract perspective and from a very concrete one as well. If you are going to recommend a NoSQL database for a new project, you’re going to have to look at code.

In this talk, we’ll examine three important contenders in the NoSQL space: Cassandra, MongoDB, and Neo4J. We’ll review their data models, scaling paradigms, and query idioms. Most importantly, we’ll work through the exercise of modeling a real-world problem with each database, and look at the code and queries we’d use to implement real product features. Come to this session for a thorough and thoroughly practical smackdown between three important NoSQL products.

Per request, the presentation slides won’t be made available.

Event-Driven Architectures

Using Factories of various abstractions, facades, and other patterns are not the only way to decouple dependencies and isolate code. A more idiomatic approach is events. All applications revolve around message passing. Passing bits to info within and outside of objects is the biggest job in any application. Message passing is typically accomplished using function and method calls. I send you a bit of information, you churn on it and send me something back and round and round we go.

Tight coupling happens because the code needs to have a live instantiation of another object so it can send it a message and maybe get a reply. These locally instantiated objects cause problems for coupling, modularity, and testability.

There is another way to pass messages to objects besides function calls: events. Javascript has excellent built-in native support for eventing thanks to the DOM.

Emitting events instead of making function calls obviously works best with global objects like utilizing AOP like logging, debugging, and code statistics that have no return values. However events can be used more deeply throughout a web application and we will see how events can play a much more centralized role in any web application.

How We Got Here, And What To Do About It

If you are developing software and getting paid for it, software process is part of your life. Even the absence of a defined process is a process of sorts. For over forty years the world of software development has been churning through forms of process, with each successor disclaiming the validity of its forebears to the cheers of those liberated from the oppressive chains of process past.

But if the latest acclaimed process is the answer, why do so many groups slough off what seemed to be working well a scant few years ago in favor of yet another choice? Furthermore, the time between process changes gets shorter and shorter. Waterfall reigned for ages, then RUP, then Scrum and XP, and now Lean/Kanban, each enjoying successively shorter seasons of favor as the de facto choice.

Process is but a framework to facilitate the collaboration of a group of people to produce a desired outcome. It is not a substitute for culture, technical excellence, discipline, and product strategy.

In this keynote, Barry emphasizes the need to continue thinking critically about the processes and practices we embrace, accounting for the context in which they exist, and the importance of reflection and refinement at both the organizational and personal levels.

Mind-blowing apps with HTML5 Canvas

Before the web, software developers implemented what we now refer to as desktop applications, using powerful graphics APIs that gave them the ability to program pretty much anything they could imagine. Then along came browsers with virtually no standard graphics support at all. Enter boring web applications, and dull work for developers.

But now, with HTML5 Canvas, developers have a powerful graphics API that lets them develop mind-blowing applications. Now you can implement desktop-like applications that run in a browser. In this session, you?ll see how.

This talk is a demo-fueled, fast-paced introduction to HTML5 Canvas. You?ll get an overview of the Canvas API, and see how you can use it to draw, manipulate images, and implement sprite-based animation. You will get a feel for what you can do with this powerful API, and you?ll get a basic understanding of how to harness that power.

Agile, Lean, and the Space Between

In early 2001, “Agile” was coined as the umbrella term for Scrum, XP, ASD, Crystal, and a few other methodologies. In 2003, Mary and Tom Poppendieck published the book “Lean Software Development: An Agile Toolkit”, and the term Lean Software Development became known among a subset of the larger Agile community.

For years, one could assume that any development group trying to improve its approach to software was applying some form of Agile Software Development methodology. In the last couple of years, Lean Software Development has seen a surge in popularity. Some groups adopting Lean perceive it as an alternative to Agile processes like Scrum, and express a sense of elitism and superiority, having “moved beyond Agile”.

While Agile Software Development and Lean Software Development originate from different sources, they are actually closely related and share a great deal of overlap. In this talk attendees will discover where each came from, and just how much of Agile and Lean are shared in the space between.

What's new in Android

Android 4.0 is a new world for Android, and for many developers who did not track with the changes to Honeycomb, represents a new UI metaphor. In this session we will look at the new UI metaphor and the APIs to work with it, including the ActionBar and Fragments, which allow you to recompose your UI for multiple screen profiles. We will also review the new Android human interface guide to see how these should be used.

Additionally, we will look at other new APIs that can be used to enhance the functionality of your application, including interactive Notifications, Drag and Drop, NFC and WiFi Direct.

Spring and Cloud Foundry, a Marriage Made in Heaven

This talk will describe the Cloud Foundry Open PaaS (Platform as a Service), with its open source, multi-framework, multi-service, multi-cloud model, and will explain in depth how to use Cloud Foundry services effectively from Java/Spring applications. Cloud Foundry allows developers to provision apps in Java/Spring, Ruby/Rails, Ruby/Sinatra, Javascript/Node, and leverage services like MySQL, MongoDB, Reddis, Postgres and RabbitMQ. It can be used as a public PaaS on and other service providers (ActiveState, AppFog), to create your own private cloud, or on your laptop using the Micro Cloud Foundry VM. Attendees will be introduced to the tools available for Spring application developers using Cloud Foundry: STS (Spring Tool Suite) Cloud Foundry Plugin, the Cloud Foundry Maven plugin or the vmc command line. Attendees will be introduced to how Cloud Foundry exposes service information to applications, and the various options Spring app developers have to leverage these services:

  • using the auto-reconfiguration mechanism that allows using services without any modifications to the app
  • using the “cloud” namespace to have an explicit control over consuming services
  • combining the profile support in Spring 3.1 with the “cloud” namespace to create applications that allow explicit control over services, while allowing applications to run locally or in Cloud Foundry without any change.

The talk will include demos of the Spring app development lifecycle with Cloud Foundry: local development with STS, local deployment to Micro Cloud Foundry for testing, deployment to
