SeaJUG is an all volunteer effort - which means items such as the website and mailing list are updated as schedules afford. You can usually count on our meetings occurring on the 3rd Tuesday of every month, and always count on them being open to all who are interested, but the next meeting agenda may not appear until the week of the presentation.

We need suggestions/volunteers for topics! If you'd like to donate your time/skills to the cause, contact Nimret Sandhu.

21 Sept 2010 : Agile & Scrum - What a developer can do

We discuss the Agile, Scrum, and XP frameworks and what a single developer can if they don't have organizational support for complete adoption. This will be pragmatic advice on how to make your job more satisfying and productive by changes within your sphere of influence. Become the change you wish to see.

17 Aug 2010 : Busy Java Developer's Guide to Games

Games? What do games have to do with good business-oriented applications? Turns out, a lot of interesting little tidbits of user-interface, distribution, and emergence, found normally in the games we play, have direct implications on the way enterprise applications can (or should) be built.

Come to this session, find out some intriguing things about what’s going on in the game industry, but more importantly, how ideas from the gaming world can turn around and answer some thorny problems in the business world.

20 July 2010 : Meet the Play Framework

The Video for this presentation is available at:
http://vimeo.com/13559378

The Play Framework is a modern web framework, built from the ground up for scalability and developer productivity. In this session, we will look at the suitability and design of the Play Framework in comparision with other modern web development frameworks. Points covered include:

• What is a dynamic language (and does Play make Java dynamic)?
• Stateless web development (and implications for scale)
• Interesting Hibernate & JPA design patterns (and anti-patterns)
• Building & deploying to the cloud (and what does that even mean)?
• What is a web framework, exactly?

Part demo, part hands-on code review, and part confessional, this session will be a great chance to think about what we build for the web, why we build it, and the future of web development.

15 June 2010 : Taking control of your application scale, database or NOSQL, using the new features in Ehcache 2.0

The video for this presentation is available at:
http://www.vimeo.com/12656606

Ehcache is an open source, standards-based cache used in a wide array of applications to boost performance, offload the database and simplify scalability. Ehcache is robust and in use in thousands of mission-critical applications. It is the most widely used Java-based cache. With the release of 2.0, you can use Ehcache to:

1. Snap into Hibernate, OpenJPA, Eclipselink and offload the database 80% or cache direct JDBC responses from the database by hand
2. Build the highest performance into your application using write-behind, ReadOnly views, NonStop caches, WAN replication, and more of the new enterprise-class features in the framework
3. Monitor and tune your caches in production with JMX or your favorite monitoring tool like Nagios

You will learn:

1. How to snap Ehcache into the latest Hibernate
2. The differences between Ehcache, expensive data grids from companies like Oracle and IBM, and Memcached
3. About the new Ehcache Monitor and how to use it
4. About the detailed roadmap of Ehcache 2 through the rest of this year.

20 Apr 2010 : Java Applications in the third World

Computation has the potential to have a serious impact in the third world. The landscape of third world computing is very different from what we are used to. There are major issues in terms of reliable electrical power, communications or any sort, financial resources and literacy. Outside of urban areas, cell phones are the only computer devices capable of serious work. A major project is Open Data Kit, an infrastructure consisting of an android application for data collection and a web application (Google app engine is the default deployment environment) for aggregation and reporting. The collections are based on JavaRosa, a version of XForms specifically targeted to mobile phones. These tools will be demonstrated together with extensions targeted at aiding in the development of forms.

These tools have been used to support a number of projects from collection of medical records to tracking missing persons in Haiti following the recent earthquake. Because the entire stack is written in Java there are many opportunities for Java developers to participate and help out.

16 Mar 2010 : JWF Smackdown

Get ready to rrrrrrrumblllllleee ...

There is a proliferation of frameworks for doing web development in Java. At this meeting the following SeaJUG memebers will talk about their experiences with some of the frameworks:

1. Eelco Hillenius: a core developer and an author of a book on the Wicket framework will be talking about it.
2. George Smith: a local consultant who has been working with Google's GWT for a few years now. He will be talking about the GWT framework.
3. Nimret Sandhu: has been working with Grails for the past year and will be talking about that framework.

Will Iverson will be moderating the talk and making sure that the frameworks behave. This will be an interactive presentation and active audience participation is encouraged ( sans throwing chairs or other objects =)

The results of the vote ( green is before the talk, black is the delta after the talk):

16 Feb 2010 : CSI: Seattle Java Edition

Most Java software problems come from the little “broken windows” – a null pointer here or there. Sometimes, however, you find yourself in a nasty section of town, with the heap, stack, and permgen brutally fighting for memory. Threads in nasty knife fights over resources. Sometimes just plain freaky things – how did I wind up with 1.5GB of HashSet allocations?

In this edition of CSI: Seattle Java Edition, we’ll look at the tools available to combat these nasty foes and even see some of them in action – we will blow up a lot of application servers and JVMs in the process, with graphic results. We’ll keep it fun and interactive, and give out a few prizes for whoever can figure out the nasty stuff.

19 Jan 2010 : Clojure

JVM based languages are the New Black. Jython and JRuby, pnuts, groovy and scala all vie for our collective attention. Perhaps you'd like to make room for another? Clojure is Rich Hickey's relatively new addition to the group. As a lisp variant it brings a functional programming approach, "code as data", macros and introduces a set of concurrency primitives that hold out the promise of finally making it easy for mere mortals to manage shared state in our applications.

Intrigued? If so, you should probably read about it at http://clojure.org and view Rich Hickey's videos at http://clojure.blip.tv. If you can't manage that, you can settle for listening to me (Stan Dyck) talk about and demonstrate some of the features of clojure at the next SeaJUG meeting. I will introduce the language syntax and design, talk about clojure IDE support, the clojure approach to functional programming, and show a bunch of demonstrations stolen from all over the Internet for your viewing enjoyment.
