One day workshop pass to HTML5 Roadshow

From former BJUG coordinator, Scott Davis:

The HTML5 Roadshow sold out in March, so we're bringing it back to Boulder -- June 17th - 21st.

The elevator pitch is "all typing, all the time." A 60 minute UG talk is a great way to get introduced to a topic, but you can't really learn it until you type it yourself and "prove it in code". The HTML5 Roadshow is a series of 1-day, hands-on, in-depth workshops taught by industry experts. This is intermediate-to-advanced "cask-strength" training targeted at working professionals in the field.>

We're rolling out 3 new workshops this time around. I'll be giving a 1-day workshop, "Node.js: More Than Just Another Web Server". And I'm happy to introduce Estelle Weyl to the tour -- she'll be talking about "CSS3: From Knowledgable to Ninja" and "HTML5: A Deep Dive".

I'll also be repeating my "The Modern Web Developer's Toolkit" and "Airplane-Mode HTML5: Mobile Web Development for Tablets and Smartphones" workshops from last time.

If you are past the superficial "Hello World" stage in your career as a web developer and would like to take your skills to the next level, we can help.

6:00-7:00: Drop the angled brackets. Discover the zen of writing (Ascii)Docs. - Dan Allen

Writing documentation is already hard enough. Why do we make it harder by burying the content in an XML schema like DocBook or wrestling with finicky WSYWIG editors? Come learn how to find the zen of writing documentation using AsciiDoc and still be able to produce beautiful HTML 5, DocBook and PDF documents--or even a slide deck like the one in this presentation!

7:30-9:00: Reducing Java Enterprise Testing to Child's Play - Dan Allen

This talk unveils the missing link in enterprise Java development: simple, portable integration tests. For many, working in enterprise Java has long been an arduous undertaking because of this void. While development life is simple with unit tests and mocks, they only take you so far. Eventually, you need to validate how your components interact and operate in their intended environment--you real need integration tests. Yet, writing integration tests has meant assuming the burden of bootstrapping all or part of your infrastructure. That's time lost and it places a mental barrier on testing. Arquillian and ShrinkWrap, two new projects from the JBoss Community, partner to tear down this barrier and reduce Java enterprise testing to child's play. Come experience how.

Arquillian, a container-oriented testing framework layered atop TestNG and JUnit, brings your test to the runtime rather than requiring you to manage the runtime from your test. Picking up where unit tests leave off, Arquillian enables you to test real components that rely on real enterprise services in a real runtime.

We'll look at how the fluent API provided by ShrinkWrap is used to package a test archive, giving developers fine-grained control over which resources are available to be tested. We'll show examples of how the test archive is deployed and executed inside standalone, embedded and remote containers. You'll witness how RPC-style (or local, if applicable) communication between the test runner and the environment negotiates which tests are executed and reports back the results. You'll walk away confident that you can write integration tests just as you would a unit test and the test is portable to multiple environments (containers).

What’s the secret? This talk reveals how Arquillian simplifies integration testing by providing a component model for tests, just as Java EE 5 simplified server-side programming by providing declarative services for application components. The test component model consists of container lifecycle management, test enrichment (dependency injection), container deployment and in-container test execution. Using a component model means your tests are portable and able to move between different environments, from single embedded or remote to multi-server to multi-cloud nodes.

Attend this talk to learn about the future of Java enterprise testing.

6:00-7:00: JSON at Work: Overview and Ecosystem

Slides here

JSON is more than just a simple replacement for XML when you make an AJAX call. JSON is becoming the backbone of any serious data interchange over the Internet. There are emerging standards and best practices that can be used to harness the energy and enthusiasm around JSON to build truly elegant, useful, and efficient applications. You’re already using JSON, and you may be thinking:

• What else is there to talk about?
• What additional tools and standards are available, and why do they matter?
• Everything is great, so how would these tools and standards help?
• How do I leverage these APIs to improve my applications?

Attendees will learn how to leverage JSON in new ways to enhance their architecture and development efforts.

6:00-7:00: Integrating Groovy and Java, Dr. Venkat Subramaniam

One of the key strengths of Groovy is the flat learning curve for Java programmers. It's more attractive when we can intermix the two languages in applications. Calling into Java libraries from Groovy is straightforward. But what about calling into Groovy classes and functions from Java? Especially, Groovy can help us create dynamic methods at runtime, but Java is statically typed. Is it possible to call these from Java? Would reflection do the trick? If those questions intrigue you, this presentation is for you.

About Venkat

Dr. Venkat Subramaniam is an award-winning author, founder of Agile Developer, Inc., and an adjunct faculty at the University of Houston. He has trained and mentored thousands of software developers in the US, Canada, Europe, and Asia, and is a regularly-invited speaker at several international conferences. Venkat helps his clients effectively apply and succeed with agile practices on their software projects.

7:30-9:00: Java at Scale: What Works and What Doesn’t Work Nearly So Well, Hank Shiffman

Java gets used everywhere and for everything, a reality that can be explained by its efficiency, its portability, the productivity it offers developers, and the platform it provides for application frameworks and non-Java languages. But all is not perfect; developers struggle against Java's greatest strength: its memory management. We'll talk about where Java needs help, the challenges it presents developers who need to provide reliable performance, the reasons those challenges exist, and how developers work around them. And we'll take a little time to talk about Azul Systems, its history of tackling Java scale issues and how it addresses the mismatch between Java and big data.

About Hank

Hank Shiffman is a Product Marketing Manager at Azul Systems. In addition to his responsibilities as Product Manager for the Zing JVM and the associated Zing Vision monitoring product, he contributes his expertise to the Marketing department, including helping to craft and tell our story to enthusiastic audiences.He has a long history explaining and helping developers to make best use of software technologies. He started on minicomputers in the late 70s, moved briefly to Lisp Machines in the 80s, and then settled into Unix-based workstations and servers. He wrote extensively about development languages and tools for Sun and SGI, and then evangelized Java for both embedded and large scale grid computing applications. He has a Bachelor's degree in Computer Science from Rochester Institute of Technology, a fact not overlooked by the Alumni Association during donation drives.

Happy Holidays from the Boulder Java User's Group!

6:00-7:00: Spock - Unit Test and Prosper - Ken Sipe

Spock is a groovy based testing framework that leverages all the "best practices" of the last several years taking advantage of many of the development experience of the industry. So combine Junit, BDD, RSpec, Groovy and Vulcans... and you get Spock!

This is a significant advancement in the world of testing.

We are grateful to TekSystems for their continued sponsorship of the Food and Soda!

7:30-9:00: MongoDB: Scaling Web Applications - Ken Sipe

Google "MongoDB is Web Scale" and prepare to laugh your tail off. With such satire, it easy to pass off MongoDB as a passing joke... but that would be a mistake. The humor is in the fact there seems to be no end to those who parrot the MongoDB benefits without a clue. This session is about getting a clue.

p>7:30-9:00: Functional Thinking - Neal Ford

Learning the syntax of a new language is easy, but learning to think under a different paradigm is hard. This session helps you transition from a Java writing imperative programmer to a functional programmer, using Java, Clojure and Scala for examples. This session takes common topics from imperative languages and looks at alternative ways of solving those problems in functional languages. As a Java developer, you know how to achieve code-reuse via mechanisms like inheritance and polymorphism. Code reuse is possible in functional languages as well, using high-order functions, composition, and multi-methods. I take a variety of common practices in OOP languages and show the corresponding mechanisms in functional languages. Expect your mind to be bent, but you’ll leave with a much better understanding of both the syntax and semantics of functional languages.

6:00-7:00: JavaScript for Java Programmers - Scott Davis

OK, admit it -- you are a Java developer who hates JavaScript. How can a language that looks so similar to Java behave so differently? How come when I copy and paste it from the Internet, it no longer works?

JavaScript is not a perfect language -- no language written in 10 days by one person could be. But it is a lot better than you think it is. In this talk, I invite you to leave your biases at the door and learn -- maybe for the first time -- the good parts of JavaScript. There is real power in JavaScript once you understand it.
