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.

This month's topic: The Feel of Scala

Scala is a new language for the Java Platform that blends object-oriented and functional programming concepts. This talk will focus on the design choices of Scala, and what they mean for developer productivity. The talk will highlight what it means to program in a functional style, and show you how Scala facilitates a hybrid of functional and imperative programming styles. The talk will also explore how Scala compares to dynamic languages such as Ruby and Python. And you'll see examples of real, production Scala code that will illustrate what it feels like to program in Scala.

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.

This month's topic: Writing a Database Application Without Knowing a Word of SQL (a.k.a. POJOs, JPA, and ORM)

We will discuss building a Java Swing application (installed or web start) that saves its data POJOs (Plain Old Java Objects) into SQL databases across the net (mySQL) or to a local embedded database (Derby) by using the JPA (Java Persistance API) and ORM (Object Relational Mapping) via Toplink or EclipseLink.

You will see that REAL applications get to benefit from technology that typically lives in the world of Hibernate and Web Apps. You gotta love portable SQL database data persistance without building any tables or writing any SQL!

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: 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: 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: 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.

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: 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.

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: Semantic Datastores - the Other NoSQL

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: JavaFX 2 is the future of RIA development

JavaFX 2 is the future of RIA development. It takes the power of a modern scene graph, adds rich animation and multimedia capabilities, and extends to the web and beyond with seamless portability. At the same time, it leverages the power and breadth of the Java language and platform, allowing full access to existing Java libraries and integration with Java client technologies like Swing.

This session will introduce you to the JavaFX 2 platform from the perspective of a seasoned Java developer. The breadth of JavaFX APIs will be explained through several examples that we will build out during the course of the session. In addition, we will showcase SceneBuilder, the new JavaFX-based GUI building tool for rapid application development. If you have heard about JavaFX before, but were not sure about taking the plunge, now is the time to see what you have been missing out on.

This talk will provide a theory of operations, systems description and possibly a demo of a live system. All code will be made available on Github.

Java at Scale: What Works and What Doesn't Work Nearly So Well

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.

You can think of Vert.x as an Actor-model-based, functional event-driven, messaging passing platform that speaks in modern protocols (JSON, WebSockets, etc) and can be used from many JVM based languages but bridges the communication gap between the browser and the server in a new way. Convincingly Vert.x is like a Node for the JVM, but with some fun enhancements.

We'll cover:

• What, Why and Who of the Vert.x project
• Discuss the problem space it is good for
• Demonstrate and discuss concepts and features of Vert.x
• Show a variety of demo apps illustrating how it works
• Current State of the Project

This month's topic is Automated Refactoring for Java.

Abstract:

This talk will focus on how engineering teams can leverage automated refactoring tools that originated at Netflix to greatly reduce the time and effort required when migrating to new versions of frameworks like Spring and JUnit and between language versions.

Does this scenario sound familiar?

Your organization has many Java-based microservices and applications that are critical for the day-to-day operation of your business. Over time, you find that your applications have a large number of dependencies on third-party technologies and libraries that have different release cadences. Invariably, your organization encounters pressures to upgrade those dependencies for any number of the following reasons: critical bug fixes, security updates, expiring support, "modernization", or technical enablement. Refactoring a single application to update its third-party dependencies can be a tricky and manual process. At the organization level, performing the same refactoring operation across all of your applications can result in weeks of effort.

This talk introduces OpenRewrite, an open-source ecosystem that specializes in mass, automated refactoring with a focus on Java source code, Maven build files, XML, YAML, and property files. We will discuss how the framework enables the creation of composable, prepackaged recipes that can be used to automate common framework migration and how these recipes can be integrated into both Maven and Gradle builds. This talk will include some live demonstrations of Rewrite's tools to perform automated migrations on real-world, Spring applications and libraries.

Bio:

Tyler Van Gorder is a principal software engineer at Moderne Inc where he focuses on frameworks and tools for automated refactoring. He is a committer on the OpenRewrite project and has a passion for building tools that enable developers to do their jobs more effectively. Prior to joining Moderne, Tyler worked as a lead software engineer for a large, e-commerce company where he focused on company-wide libraries using Spring, Spring Boot, and Spring Cloud. In his spare time, you might find Tyler on a basketball court or hiking, with his wife, in the mountains around Portland.

This month's topic: Code Generation on the Java VM

Code generation has become a mainstream technique for building modern Java applications.

in person meetup

Portland Java User Group

Join us for the PDX JUG July Meetup where we will dive into the world of Structured Concurrency. Structured Concurrency is a preview feature in Java 21 and will simplify the common scatter-gather kind of pattern.

Tyler Van Gorder is our speaker, he has previously spoken about Virtual Threads in Java, and Structured Concurrency is a great complement to Virtual threads. In Tyler's words:

"Simplify concurrent programming by introducing an API for structured concurrency. Structured concurrency treats groups of related tasks running in different threads as a single unit of work, thereby streamlining error handling and cancellation, improving reliability, and enhancing observability."

We will briefly recap how virtual threads work and then explore how related tasks can be grouped as a single unit of work. We will cover the different shutdown strategies and examine how the programming model compares to similar functionality using a reactive framework."

Don't miss this opportunity to network with fellow Java enthusiasts, share your experiences, and learn from each other. Whether you are interested in web development, software development, or JVM languages, this meetup is open to anyone who is passionate about Java.
