Testing REST: Functional Correctness At Scale Using AKKA and REST Assured

This month's speaker is Steve Hall who has 20 years of experience designing and delivering unique solutions to business problems. Steve is a Lead Software Engineer working with REST, big data and social solutions at Nike in Beaverton, OR.

His current project enables millions of users on mobile devices to follow and just as easily stop following any digital content that may be of interest to them. The team has found that building these systems using REST and NOSQL can scale massively. However, achieving that scale requires some unique approaches for handling the volumes of data that needs to be stored. Tonight he will present an overview of what the team has learned about data modeling in a typical NOSQL datastore such as Cassandra or Dynamo. Following that he will discuss why traditional unit, integration, and performance testing approaches proved to be inadequate, and why the team went looking for a better solution.

Having presented the problem, he will then present how the team has applied AKKA and Rest Assured to create a testing framework that proves the system is functionally correct at scale, and why it matters.

Finally, he will close with a few insights for other ways that AKKA could be useful when working at large scale.

Stalking the Lost Write: Memory Visibility in Concurrent Java

Throughout its 18-year evolution, the Java language has played an industry-leading role in the tricky business of specifying the behavior of concurrent programs. Java's contribution became particularly evident with the introduction of the Java Memory Model (JMM) in Java 1.5.

This is an area in which a down-to-the-metal understanding can help developers strike the right balance between safety and performance, so we'll start by motivating the discussion with counterintuitive low-level examples. Then we'll work "up from the weeds" to describe the JMM as a basis for more familiar programming patterns. We'll touch on how C, C++, and C# deal with the same issues and give a nod to functional languages and Java 8.

This material can help most developers become more insightful about concurrency issues in their code. Be there or be unsynchronized!

The NoSQL movement has given developers many more data storage options, each with their own design considerations and trade-offs. One of the quieter options, semantic data stores (also called triple stores or quad stores), provide an interesting hybrid of key-value and graph database features, while offering a data model based on a W3C recommendation (RDF) and a standardized query language (SPARQL) that will feel familiar to anyone experienced with unfashionable SQL.

This talk will cover the basics of data modeling with RDF and how to use the open source Jena Semantic Web Framework to add a semantic datastore to a Java-based Web application.

This month's topic: Gradle

Come to the session if you want to participate in learning more about Gradle. Gradle is a powerful layer of Groovy built on top of a number of established tools and libraries. Smart guys have borrowed from the pioneering work of Ant, Maven, Gant, Buildr and come up with an expressive, concise, and convention-rich build tool for the Java family.

For this session, there won't be any slides. I'm also not going to stand up and talk at you. Instead, I'm going to rely heavily on your involvement. I'll start with an introduction to Gradle, and then very quickly go into using it in practice. After a few minutes of that I'll open it up to go wherever we're most interested in. I'm not a Gradle expert, yet I believe that my Groovy background in conjunction with a few days of earnest usage have taught me a lot. This session will rely heavily on an internet connection, and we'll be googling for answers together if need be.

Do this ahead of time:

What is your intention for the session? Spend some time deliberately focusing on what it is you want out of the session. Bring that will you and share it with us. It will help us all focus on what's important and go some way to helping you get the most out of the session. Also, go have a quick read about Gradle on their website. That will save us all some time, help us get to the interesting details sooner, and be a good source of informed questions for you.

This month's topic: Logging Last Resource (LLR) optimization of XA

Almost every transaction executed on a Java EE Application Server winds up distributed over multiple resources such as JMS destinations and JDBC datasources. Standard OTLP systems employ the XA-2PC protocol, a presumed-abort variant of the Two-Phase Commit protocol to make sure that either all resources commit successfully or all resources abort the transaction if at least one resource fails. As any distributed consensus protocol, XA-2PC is expensive. In this talk, we present Logging Last Resource (LLR) optimization of XA (actually, its Java EE "translation" in form of the JTA spec) in Oracle WebLogic Server. LLR's effectiveness has been validated in world record results achieved by the Oracle stack in the SPECjAppServer2004 benchmark and by high-profile customers in mission-critical applications.

Speaker: Gera Shegalov

Gera has worked in the areas of workflow management, temporal databases, messaging, and recovery. He is currently with Oracle Database High Availability. In his prior role at Oracle, he was part of the Java Platform Group where he worked on the messaging infrastructure such as OC4J JMS, AQ JMS integration, WebLogic FileStore, and LLR. Prior to joining Oracle, Gera worked at the Max Planck Institute of Informatics in Saarbruecken, Germany and interned at Microsoft Research in Redmond, WA.

This month's topic: Rich Internet Clients: A moderated, but open discussion on what is the "right technology" for an internet application.

Bring your opinions, experience and personal bias and join in a lively discussion on a highly pertinent topic.

Topical questions include but are not limited to: Applications written using HTML, CSS and Java Script (DHTML) have some advantages but what requirements, if any, would sway a project towards -Flash, Applets or Java F/X? Is there significant differences between consumer versus business based applications that would cause cause a particular technology to be used? Are they days of Flash numbered or is the current trend towards pure DHTML doomed because of fragmentation in the browser market?

This month's topic: Teaching Girls and Boys to Program Computers

Why is it that the percentage of women graduating with computer science degrees around 50% in countries like Sweden, China and India, but less than 20% in America? As a "Geekdad" with a daughter, I found this unacceptable, and decided to do something about it... I went back to school... elementary school that is, to teach programming to the kids. My goal was to find an environment and a style that would encourage girls with curiosity to enjoy being controlling computers in creative ways, and in the process, encourage and involve every kid.

My talk discusses the journey of coming up with a girl-friendly curriculum for teaching programming that boys wouldn't notice anything different. I then show off some of the new crop of "Integrated Learning Environments", i.e. Alice, E-Toys and Scratch. I finally give an overview of my "Computer Club" and how others can use what I've done to teach others.

Speaker: Howard Abrams

My first job in high school was teaching Basic and Logo programming to 8 year old kids; however, I haven't taught since graduating from college. After programming for 25 years (and Java for 12), I'm now intrigue about returning to my roots and working with the next generation.

This month's topic: An Argument for Semantics - Why Developers Should Give a Hoot about OWL

In the push to make use of tagging and other forms user-driven information architectures, developers have overlooked the value of adding semantics, or contextual meaning, directly to the data that powers web sites and applications. The addition of Microformats to a Web site's markup can further the exchange of semantic information such as contact information for people and events. For the most part, however, web sites and applications are still populated by largely non-semantic prose organized in large blocks of HTML or generated from the walled gardens of relational databases and data warehouses.

While everyone agrees that HTML isn't going away anytime soon, several Web Standards have arisen over the last few years to help application developers store, serve, and distribute information with ever-increasing levels of semantics and meaning. The current pinnacle of the Semantic Web Standards pyramid is OWL - the W3C's Web Ontology Language. In this talk I will describe the roots and basics of OWL and how it can be used to power the next generation of smart, data-enabled Web applications.

This month's topic: The Spring Insight console and Roo

The Spring Insight console, part of tc Server Developer Edition, is a dashboard view of real-time Spring application performance metrics. Without changing their code, developers can use Spring Insight to detect, analyze and diagnose application performance issues right from their desktops.

A graphical look at application performance: Within Spring Insight, application performance is graphically displayed via response time charts and histograms, providing developers an easily digestible view into where processing time is spent.

Easy navigation to identify the root causes of concerns: Expandable call trees enable developers to drill down into application requests and controller actions.

Integration with SpringSource Tool Suite to fix problems: By integrating SpringSource tc Server Developer Edition with SpringSource Tool Suite, developers gain a deeper understanding of how the application is functioning and performing by isolating a transaction trace and quickly jumping to the portion of code that is causing a problem.

This month's topic: Java Performance, the Lifecycle Approach: The Game Has Changed

Java Enterprise Performance Tuning typically is viewed as someone else's job.

QA will do it. Operations will figure it out. Isn't the Dev guys supposed to find these things? But in fact it can and should be done across the lifecycle.

We will explore this new concept and other topics such as:

GC diagnosis while under load

Is my Framework doing what I want?

Hello? Is this thing (caching) on?

Who's your daddy? (How do services really interact)

This month's topic: Java Performance Testing with Project Bonneville

Project Bonneville is Chris Cowell-Shah's evenings-and-weekends open source project for measuring the performance of certain core Java SE features. Chris will review the results of these benchmarks with an eye to addressing the following questions:

How does performance vary across JVM vendors?

How does performance vary across JVM versions?

How does performance vary across operating systems?

How does the performance of 1.4 features differ from their 1.5+ replacements?

How true are commonly held assumptions about Java performance?

Can we generate simple rules of thumb for high-performance Java SE programming?

There will also be a short discussion of the tradeoffs between micro- and macro-benchmarks. Because this is a work in progress, comments and observations about Project Bonneville's benchmarking methodology, or suggestions for future benchmarks, are especially welcome.

Chris promises a LOLCAT-free presentation, though there may be a slide or two of his kids.

Speaker: Chris Cowell-Shah

Chris does quality assurance for Oracle's Java-based Rules engine. He has also worked as an IT consultant for Accenture, and as a researcher for Accenture's Palo Alto research and development lab.

Many people also go for a drink and further discussion following the meeting, at a location determined ad hoc (more often than not, Jax on 2nd).

Agenda for this week: * 6:00 Intros * 6:15 Jerry leading a discussion about open source alternatives to Pipes. * 6:50 Work session. Bring your issues with Yahoo Pipes or other RSS feed hackery & we'll pair up to help each other

This month's topic: Your Brain on lambda(x)
Functional programming is (again) a hot topic among developers. Languages such as Scala and Clojure have functional concepts at the core of the langauge, and even more solidly object-oriented languages such as Groovy and C# 3.0 include functional concepts. This talk will cover whether langauge really matters, some functional techiques that enhance the power of a languge, how to implement some of these using existing Java syntax and semantics, and the future of functional additions to the Java langauge.
Speaker: Phil Varner
Phil is a software developer with Oracle, working on the Business Rules component of Fusion Middleware.

[Full details at http://upcoming.yahoo.com/event/1494004/ ] Several of us have read Marshall's How to: Build a Social Media Cheat Sheet for Any Topic http://www.readwriteweb.com/archives/how_to_build_a_social_media_cheat_sheet.php where he integrates data from many different sources and uses various plumbing tools to pull it all together. Marshall is a master of tools like Yahoo Pipes and Dapper, and it will be great to have him presenting at our Jan 27th meeting.

This month's topic: Clojure: Functional Programming for the JVM (Howard Lewis Ship)

Talk about strange bedfellows: what happens when you mix one part Lisp (one of the oldest computer languages), one part Java (so young, yet so well adopted), a healthy serving of functional programming, and a state-of-the-art concurrency layer on top? That's Clojure, which "feels like a general-purpose language beamed back from the near future." Clojure embraces functional programming with immutable data types and first class functions. It is fully interoperable with Java. Clojure's approach to concurrency includes asynchonous Agents, and Software Transactional Memory. Clojure is fast, elegant, dynamic, and scalable: a language for the future, today.

I've decided to resurrect the Portland Data Plumbing Group to give us a place to talk about RSS feed hacking, Yahoo Pipes, Dapper, and other related technologies.

We'll be having these meetings on the 2nd Tuesday of every month at 6pm.

The agenda for the first meeting:
- Intros
- Round table discussion: each person gets 3-5 min to talk about the coolest thing they've done to manipulate an RSS feed.
- Talk about ideas for future agendas.

A big thanks to Bill (aka @wajiii) for finding a place for us to meet at Oracle!

You'll want to join this Google group to get announcements about future events: http://groups.google.com/group/portland-data-plumbing

         

This month's topic: "Simplify Java Web Development with Able"

Patrick Lightbody will present his work on a new open source initiative named Able. Able is a combination of a library and quickstart template that aims to tightly integrate several modern Java frameworks: Hibernate (persistence), Stripes (web framework), Guice (core container), and DWR (AJAX). By taking advantage of libraries that embrace annotations and generics, Able simplifies Java web development and provides integration at several levels, including validation, transaction handling, and object lifecycle management.

If you want to do some reading in advance, here are some relevant links:

Hibernate: http://www.hibernate.org
Stripes: http://www.stripesframework.org
Guice: http://code.google.com/p/google-guice
DWR: http://directwebremoting.org

Speaker: Patrick Lightbody is the founder of BrowserMob, a new on-demand load testing product that uses real web browsers. Patrick is also the Managing Director of OpenSymphony Group, a non-profit open source group dedicated to the creation of high quality, open source Java-based components. Recently, Patrick oversaw a rare occurrence in the open source world: a merger of two competing projects, OpenSymphony WebWork and Apache Struts. He is also the founder of OpenQA, an open source group dedicated to bringing quality open source testing tools to the market. Patrick is a published author and an established leader in the Enterprise Java community.

This month topic: TBD.

Topic: Using Groovy to Unit Test Java Code As you know, Groovy is a slick scripting... er, dynamic language that integrates very well with the Java platform and Java technologies. This presentation will go over a way to introduce Groovy into your organization and programming environment via unit testing. After a brief introduction to the language, we'll go over why Groovy can make unit testing easier. Speaker: Howard Abrams Howard jumped on the Java bandwagon during the last millennium and has been working with Groovy off an on for a few years. He currently works for Cordys supporting their business automation process software.

Topic: Writing Web Applications in Java with GWT

Oracle Downtown Campus 8th Floor - Room 8005 Pacwest Center 1211 SW 5th Avenue Portland, OR

Topic: "Design Patterns" in Dynamic Languages

The Gang of Four book should have been entitled "Palliatives for Statically Typed Languages", because the recipes it provides are cumbersome solutions to the problems it poses. Using powerful languages makes the solutions in the GoF book look hopelessly complicated. This session shows how to solve the same problems concisely, elegantly, and with far fewer lines of code using the facilities of dynamic languages.

Speaker: Neal Ford
