Previous NYC Java Meetup - a joint meeting with NYC-GTUG on Thursday May 13 - please RSVP at http://meetup.com/nycjava

Intro Speaker: Timothy Fagan ongoing series on Java Best Practices will resume in June!

Featured Speaker: (remotely from CA) Stephen Ng and Noel Yap

Topic: Android Development and Testing: an unauthorized guide to some unorthodox techniques.

The primary development language for Android is Java, which means you get to write mobile apps in a familiar language with great IDE support. But because Android runs on a custom (Dalvik) VM, writing tests that run quickly and locally can be a challenge. This talk will focus on three experimental techniques for unit and integration testing:
- Using PowerMock to enable unit testing on the Java VM
- Using Roboguice to facilitate dependency injection
- Using a sqlite3 wrapper to enable sql testing

Stephen Ng is a Software Engineer in Test at Google, where his day job has nothing to do with Android development. He is the author of a popular open source Android application, GeoBeagle, which is coded using the techniques described. He is a graduate of M.I.T.

March NYCJava Java Meetup - Tues March 30 at Oracle (Sun Microsystems) - RSVP at http://meetup.com/nycjava


We have a special guest speaker for this coming Tuesday's March Java Meetup: Bjorn Freeman-Benson, formerly CTO of Eclipse and now VP Development of NewRelic. A special thanks to Mitch Sonies for arranging this!

Agile All The Way Down
You are an agile Java developer and you work in an agile shop, but are you agile all the way through deployment and production? You are using a full complement of profiling, testing and load generation tools for your Java app, but we all know that even with the most rigorous pre-deployment QA, "issues" will sneak through. To catch these, all serious apps use production monitoring of one kind or another. The ah-ha moment comes when we realize that we can use that same production monitoring to increase our agility: we can shorten the pre-production testing cycles and push new iterations into production with minimal testing. I'll talk about how we've done this, and how our customers have done this, and how other great engineering projects in history have done this. With real life examples and stories of how we've become more agile, I hope to enthuse you to become "agile all the way down".

Bjorn Freeman-Benson:
After five years at the Eclipse Foundation working with committer community, Bjorn Freeman-Benson is now part of the engineering team at New Relic. A software language aficionado with experience in open source, closed source, big companies and small companies (Eclipse/Java, Amazon/Perl, Rational/C#, Gemstone/Smalltalk, OTI/Smalltalk, ...), he has a variety of war stories, many of them interesting. He has an M.Sc. and a Ph.D. in Computer Science from the University of Washington, and is happy to talk at length about his passion for orienteering and/or his love of flying and electric cars.

October General Meeting - NYC Java Meetup

A very special guest speaker, coming all the way from the island of Crete, yes none other than Dr Heinz Kabutz will make a special appearance! This renown master Java specialist gave us an excellent presentation on the secrets of concurrency two years ago and this time will speak on the intricacies of reflection. In addition to his appearance at our group, he will also offer a Java Specialist Master Course on November 10-13 as part of Sun's Extreme Learning Workshop series here in NYC!

Speaker: Dr Heinz Kabutz

Topic: "Reflection Madness"

"In this presentation, we will look at some advanced uses of reflection to delegate method calls automatically, to determine where we are being called from and to create new enum values dynamically for unit test purposes, including modifying the switch statements on-the-fly. We will look at how we can use the stack information to determine the class type in a static context. We will demonstrate how Externalizable allows the private state of an object to be read and then modified. Lastly we will demonstrate how we can construct new objects without calling any of the available constructors. This talk will be aimed at the advanced Java specialist who does not shy away from reflection code. Topics from the Java Specialists Newsletter and related research."

Dr. Heinz Kabutz is best known as the creator of the Java Specialists' Newsletter, targeted to expert Java Developers. Since its inception in November 2000 the newsletter has grown to include an audience of more than 50,000 programmers in 120 countries and become one of the most widely distributed, independent Java Newsletters in the world. Dr. Kabutz uses the experience gained "in the field" to write articles in his publication and he was chosen as a Sun Java Champion.

Session Title: Java EE 6: A Community Update

Abstract:
This session is the latest update on the progress of Java EE 6 (JSR 317). The aim of the session is both to inform as well as encourage feedback.

Java EE 6 brings a number of profound changes to the platform. It drops a handful of outdated APIs, breaks up the monolithic platform into profiles and aims to add extensibility points as well as adding useful enhancements like standardizing JNDI naming. We will explore all of these changes in this session. We will also briefly overview some of the most important JSRs being developed under the Java EE 6 umbrella such as JSF 2.0, WebBeans, EJB 3.1, JPA 2.0, JAX-RS and Servlet 3.0.

A central goal of this session is open-ended discussion, so please do feel free to bring your questions, comments and ideas.

November Topic: EJB 3.1: A Community Update

6:30pm 76 Ninth Avenue (between 15th/16th St), 13th floor - RSVP required - email garyrusso @ hotmail.com

Abstract:

This session explores the latest features proposed in EJB 3.1 (JSR 318). The aim of the session is both to inform as well as encourage feedback.

EJB 3.0 was a radical transformation geared towards usability. EJB 3.1 aims to go further down the path of simplicity while adding a number of useful features. In this session we will see all of the features that have been discussed in the expert group so far such as optional interfaces, singleton beans with concurrency control, annotation-driven cron-like scheduling, asynchronous processing support, easier deployment, as well as EJB lite. We will also take a look at the features still being discussed such as standardized JNDI naming as well as support for running EJB 3.1 in Java SE environments.

The session will leave time for open-ended discussion, so feel free to bring your thinking hat!

Aug General Meeting: a special meeting: we are hosting the Semantic Web Meetup

'note: please rsvp at above meetup.com link - (if filled you can still show up bring id)

Topic: Clojure for the Semantic Web Exploration

Meetup Track: This Session is hands on and technical

Speakers: Rich Hickey and David Siegel

Rich Hickey will join forces with the New York Semantic Web Meetup to extend Clojure for the use in the development of Semantic Web applications.

http://clojure.org

Clojure is a dynamic programming language that targets the Java Virtual Machine. It is designed to be a general-purpose language, combining the approachability and interactive development of a scripting language with an efficient and robust infrastructure for multithreaded programming. Clojure is a compiled language - it compiles directly to JVM bytecode, yet remains completely dynamic. Every feature supported by Clojure is supported at runtime. Clojure provides easy access to the Java frameworks, with optional type hints and type inference, to ensure that calls to Java can avoid reflection.

Clojure is a dialect of Lisp, and shares with Lisp the code-as-data philosophy and a powerful macro system. Clojure is predominantly a functional programming language, and features a rich set of immutable, persistent data structures. When mutable state is needed, Clojure offers a software transactional memory system and reactive Agent system that ensure clean, correct, multithreaded designs.

Session prep:

Introduction to Clojure (from June's General Meeting below)
http://blip.tv/file/9...


June General Meeting:

Topic: Clojure for Java Programmers

Presentation now available online (with audio):
(Thanks Rich!)
http://clojure.blip.tv/file/982823

Speaker: Rich Hickey

Clojure http://clojure.org is a dynamic functional programming language for the JVM. This talk will provide an overview of Clojure, including a gentle introduction to its syntax for those with no prior experience with Lisp, an overview of features, and a discussion of Java integration. Also covered will be Clojure's approach to functional programming, immutability, and concurrency and how they help solve some of the problems faced by Java programmers using threads and locks today.

Bio:

Rich Hickey, the author of Clojure, is an independent software designer, consultant and application architect with over 20 years of experience in all facets of software development. Rich has worked on scheduling systems, broadcast automation, audio analysis and fingerprinting, database design, yield management, exit poll systems, and machine listening, in a variety of languages.

Combined meeting with NYC Java Meetup

Speaker: Cameron Purdy - Founder, Tangosol

Title: Creating Grid-Based Data Infrastructures for the Enterprise


Thanks Cameron for the presentation, slides are now available, thanks to Sun Microsystems for the location, and Sun and Prentice Hall for the door prizes and thanks to the member who posted the slides at the meetup site.

Abstract:
Grid based infrastructures are being developed, deployed and used to achieve unlimited application scalability and continuous availability across multiple datacenters. Understanding the additional capabilities of these infrastructures and how they can be used to solve increasingly difficult and complex problems will help to ensure that organizations are getting the maximum utility from Grid Computing. This session will focus on how Data Grid capabilities function, such as coherent in-memory caching, dynamic data partitioning, and parallel query and process execution, and how they are being mapped onto grid infrastructures. Organizations are using these Data Grid capabilities in order to provide real time risk analytics, complex event processing and algorithmic trading, and "follow-the-sun" order management systems. Additionally, the session will draw specific attention to how organizations are able to implement these capabilities on a global scale.

Attendees Will Learn
  • How Data Grid capabilities function.
  • How organizations are using them to solve complex computing problems.
  • Examples of how organizations are leveraging this on a global scale.

Speaker Bio:

Title: The Secrets of Concurrency


slides now available: http://www.javaspecialists.eu/talks/nyc07/Concurrency.ppt
Abstract:

From the first version of Java, we have been able to create multiple threads. Initially, this was mostly used for making our GUIs more responsive. For example, we would read a file using a separate thread from the main Swing thread, updating the GUI as to the progress. Running many active threads on one CPU seldom made the program faster, on the contrary, the swapping overhead frequently bogged down the machine.

However, in the last few years, the speed increase of CPUs has not been the clock speed, but the number of cores on each chip. We are in a position now where we can get a job done much faster by splitting it between multiple threads.

Unfortunately there is still a lack of understanding of the mysteries surrounding threading. This has caused programmers to write code that is fundamentally incorrect, not taking into account best practices for threading.

Here is an example of such incorrect code, seen today on a web forum:

synchronized (namedQueues) {
try {
namedQueues.wait(5000);
} catch (InterruptedException ie) {
// Can safely ignore this
}
}
if (isInterrupted() || isStopped())
break;

In this talk, we look at ten laws that can help us to write more correct threaded code. We will now briefly summarise these ten laws:

1. The Law of the Sabotaged Doorbell
We show how to manage the InterruptedException. Since they are thrown by several methods in Java 5, this is useful to know.

2. The Law of the Distracted Spearfisherman
When analyzing threading problems, we should know what every thread is doing. If we gloss over one thread without understanding it, we can easily miss a problem.

3. The Law of the Overstocked Haberdashery
Threads use up resources, even if they are not active, putting an upper limit on the number of threads in our system.

4. The Law of South African Crime
Fields can be cached locally by threads to improve the performance of retrieving their value. Thus, if one thread modifies a field, the other threads might not see the updated value.

5. The Law of the Leaked Memo
The Java Memory Model allows the hotspot compiler to reorder statements, as long as the final result is still correct. This can lead to some results which seem logically impossible.

6. The Law of the Corrupt Politician
Data races can cause the best objects to become corrupt. They can be really difficult to detect and analyse. In this law, we look at how wecan avoid these problems.

7. The Law of the Micromanager
Adding synchronization to our code can cause problems with contention, where threads are waiting for each other to execute a critical section.

8. The Law of Greek Driving
The rules of the road for Java threading are quite strict, but not enforced by all of the Java Virtual Machines. Even though your code seems correct, it might still be wrong.

9. The Law of Sudden Riches
Sometimes a system has latent defects that are only seen every few months. When running the system on faster hardware, these defects are amplified and can happen more frequently.

10. The Law of the Uneaten Spinach
It is often possible to detect deadlocks in Java, but unfortunately it is impossible to recover cleanly. The only option is to analyse the problem that caused it and then restart the JVM.

This talk has been presented at The Server Side Java Symposium in Barcelona 2007 and NLJUG JFall 2007, both times with excellent attendance and feedback.

Prerequisites: Attendees should be confident in Java SE and should have ideally worked a bit with threads before. The talk does have something for everybody, but is mainly aimed at the intermediate to advanced developer. There are code samples and a short demonstration.

What you will get out of the talk: You will learn several tips that will help you in writing correct threaded code in Java.

September General Meeting: Thursday, Sept 13, 6:00-9pm (Note: 2nd Thursday in Sept)
Speaker: Inyoung Cho from Sun Microsystems
Topic: Java Scripting: Java FX/Script and JRuby ->slides<-

The Java Platform supports multiple language solutions including scripting and dynamic languages. This session will offer a brief technical overview of scripting in the Java language and summarize the scripting features in Java Platform, Standard Edition 6 (Java SE 6), and exposes the audience to the Java FX script technology, and JRuby.

The Java FX Script is designed to deliver secure, interactive content, applications, and services that run on a variety of clients. To simplify and speed the creation and deployment of high-impact content for a wide range of devices, Sun announced JavaFX, a new family of products based on Java technology designed to enable consistent user experiences, from desktop to mobile device to set-top box to Blu-ray Disc. JavaFX Script is actually a declarative Java scripting language with static typing for good IDE support and compile-time error reporting (unlike JavaScript...), type-inference, declarative syntax, and automatic data-binding with full support for 2D graphics and standard Swing components as well as declarative animation. You can also import java classes, create new Java objects, call their methods, and implement Java interfaces. In Java FX Script section, we'll look at what is in JavaFX Script, how to use it and with examples and demos.

JRuby is an implementation of the Ruby programming language targeted at the Virtual Machine for the Java platform (JVM platform). Ruby is a dynamically typed object-oriented language with support for blocks, continuations, and all the usual OO trimmings. In JRuby section, we'll show you how to apply Ruby on the JVM software to common use cases, and projects that utilize JRuby and demonstrates the most compelling capabilities offered when Ruby and Java technology work together.

August General Meeting: First Thursday, August 2 6:30pm
(no rsvp required but seating is limited)

Location: NYPC (New Yorker Hotel - 34th and 8th Ave 5th floor)
Topic: Getting Started with JPA using Hibernate 3

slides and source code presented and source code not presented

Speaker: Reza Rahman

Bio:
Reza Rahman is the chief architect at Tripod Technologies, an IT solutions company focusing on Java EE in the Baltimore-NYC corridor. He is the co-author of "EJB 3 in Action" from Manning Publishing. Reza has been working with Java EE since its inception in the mid-nineties. He has developed enterprise systems in the publishing, financial, telecommunications and manufacturing industries. Reza has been fortunate to have worked with both EJB and Spring/Hibernate. He coordinates the Philadelphia JBoss User Group.

Description:
The Java Persistence API (JPA) aims to be the de-facto standard for ORM based persistence. Hibernate 3 is one of the earliest and most popular ORM tools implementing the JPA standard. This session is a hands-on introduction to JPA using Hibernate 3.

During the course of this session, we will configure Hibernate 3 from the ground up to work with JPA in a standalone application, solve a realistic persistence problem step-by-step and explore some of the key features of JPA along the way. We will explore basic annotation-driven mapping, generating keys, mapping relations, performing basic persistence operations and forming complex queries using the Java Persistence Query Language (JPQL).

You are encouraged, but not required to bring your laptop and code along throughout the session. Please see the following prerequisites to install before the meeting

July General Meeting: Tuesday June 26 (not Thursday July 5)

Location: Microsoft, 1290 Avenue of the Americas, 6th floor)

Topic: Why Projects Fail

--- slides now available at http://www.stellman-greene.com - thanks Andrew and Jennifer ---

Special Event: Joint meeting with the New York City Chapter of the International Association of Software Architects (IASA).

Topic: Why Projects Fail Speakers: Andrew Stellman and Jennifer Greene

Publications:
Applied Software Project Management
Head First PMP: A Brain-Friendly Guide to Passing the Project Management Professional Exam.

Bio:
Andrew Stellman, despite being raised a New Yorker, has lived in Pittsburgh twice. The first time was when he graduated from Carnegie Mellon’s School of Computer Science, and then again when he and Jenny were starting their consulting business and writing their first project management book for O’Reilly. When he moved back to his hometown, his first job after college was as a programmer at EMI-Capitol Records—which actually made sense, since he went to LaGuardia High School of Music and Art and the Performing Arts to study cello and jazz bass guitar. He met his coauthor, Jennifer Greene, when they worked together at the same financial software company, where he was managing a team of programmers. He’s since managed various teams of software engineers and requirements analysts, and led process improvement efforts.

Jennifer Greene studied philosophy in college but, like everyone else in the field, couldn’t find a job doing it. Luckily, she’s a great software tester, so she started out doing it at an online service, and that’s the first time she really got a good sense of what project management was. She moved to New York in 1998 to test software at a financial software company. She managed a team of testers at a really cool startup that did artificial intelligence and natural language processing. Since then, she’s managed large teams of programmers, testers, designers, architects, and other engineers on lots of projects, and she’s done a whole bunch of procurement management.

Special Note:
Andrew and Jennifer are currently working on "Head First C#".
It's expected to be one of the biggest O'Reilly releases in 4th quarter 2007.

There were good door prizes (everyone got a book)



May monthly general meeting - Monday April 30, 6:30-9pm

Speaker: Elliotte Rusty Harold
Bio: Elliotte Rusty Harold, adjunct professor of computer science at Polytechnic University in Brooklyn, author of numerous books on Java and XML. His Java news website: http://www.cafeaulait.org and blog: http://cafe.elharo.com

Topic: Java 7 and Beyond
2007 will go down in history as the year Sun Microsystems gave up the reins of the Java platform, releasing it under an open source license to the Java developer community. In this talk Java developer Elliotte Rusty Harold predicts new directions for the Java platform, in everything from scripting to bug fixing to new syntax. We'll talk about various proposals for both the language and libraries including closures, type inference, I/O, and more.

thanks to all who came, especially to our speaker and for posting the presentation at his cafeaulait.org website: http://www.cafeaulait.org/slides/nycjava/java7/Java_7_and_Beyond.html
