16 Sept : The Busy Java Developer's Guide to Performance and Scalability

admin — 2008-09-09T21:53:43-08:00

Note : This month's speaker is being facilitated by the folks who run the NoFluffJustStuff conference which is going to be hitting Seattle on the weekend after the meeting. Some lucky audience member will get a free pass to the conference ( worth $995/-) at the meeting.

Presentation
Wondering why your enterprise Java app just… sucks? Trying to figure out why you can't get more than 10 concurrent users online at the same time? Looking for ways to try and spot the slowdowns and ways to fix them? In this talk, we'll look at the various things that can occur in an enterprise Java app (from the smallest web site to the largest multi-resource environment) to make your Java apps perform and scale less well than they should, and how you can work to correct them. We'll examine a variety of broad concepts to apply in architecture and design, and examine what factors make an enterprise application slow, then use a variety of tools to figure out how to remedy them.

15 July 2008 : Java and the One Laptop per Child project

admin — 2008-07-11T13:53:23-08:00

The One Laptop Per Child project is an ambitious project to develop a cheap, rugged PC designed for the educational market in the third world. The idea is to develop a system designed to allow every child in the third world to have a computer as an aid to their education. The target system was designed to cost $100 and be powered by human power since electricity in many villages is unavailable or unreliable.

The OLPC (frequently called the XO) ships with a specially designed set of applications. All code shipping with the system is fully open source. Most system software on the platform is written in Python. There is a unique operating system called Sugar layered on top of a version of Red Hat Linux. Because Java is not completely open source, java is natively shipped on the XO.

This talk describes and demonstrates the capabilities of the XO. The projects success and failures in meeting the announced goals are reviewed. While Java does not ship natively on the XO, it is possible to install Java and to run significant Java applications, a capability which may prove useful, especially in third world deployments. Finally the future path of the XO project is discussed.

Speaker Bio:
Steven M. Lewis has been working in the software development field since the early 1970’s. He had a PhD in biophysics and taught bioengineering at USC for 13 years. His specialties were simulation, respiratory control and gas exchange. He led the effort to convert software at IDX from C to Java in the mid 90’s. He was principal architect at OneWeb Systems where he build an XML based framework for delivery of web pages. He has been the Director of Development at Unified Signal Inc a company developing virtual private cell phone networks. He has lectured extensively on Java and helped develop the UW Extension’s advanced Java course. He recently worked at Combimatrix to develop the software for a machine to synthesis DNA microarrays on Silicon chips in Collaboration with Furuno Biologics. He is currently an independent consultant.

15 Apr 2008 : Cool New Developments for Java on the Web

admin — 2008-03-30T16:41:08-08:00

We are poised for a renaissance of Java on the World Wide Web. With the release of Java SE 6 Update 10, applets will once again become a viable deployment vehicle. A fusion of applet and Java Web Start technology makes applets as powerful as desktop applications. New extensions for JavaFX technology can immediately and transparently be deployed into applets on a web page. Advanced visualization technology like NASA's World Wind Java can be embedded in a web page and scripted from JavaScript. This talk will show some of the possibilities for applet deployments today, with plenty of examples.

Kenneth Russell joined Sun Microsystems, Inc. in 1999. He is the architect of the next-generation Java Plug-In and the project lead for JOGL, the Java binding to the OpenGL API. His background and interests include high-performance 3D graphics and programming in dynamic languages, especially the Java(TM) programming language. He holds Bachelor's and Master's degrees from the Massachusetts Institute of Technology.

18 Mar 2008 : GridGain – Java Grid Computing Made Simple

admin — 2008-03-12T11:21:43-08:00

The talk usually takes about an hour and is split into two parts: essential introduction into grid computing and live coding demonstration. In the first part I give informal introduction to grid computing void of usual over-generalization and abstract definitions. In the second part of the talk I give live coding demonstration that shows that Java grid computing can be really simply and productive to use – and one can even build a full grid application in front of the audience in less than 15 minutes from scratch.
