[ Technology ] A Database for Nomadic Users

Listen to Roger Brinkley interview Rick Hillegas about Java DB.

Java DB (Sun's distribution of Apache Derby) continues to prosper.

The potential for deployment in mobile devices and nomadic applications can be tremendous, while its ease of use and deployment continue to make it attractive in client-server modes.

[ Technology ] Database Price-Performance on Sun All Open-Source Platform

More good PostgreSQL and open-source news! 

In the first week of July 2007, Sun announced a very attractive SpecJ2004 result for an all open-source Sun stack, including PostgreSQL on Solaris on Niagara.

Josh Berkus and Jignesh Shah have already written about the recent SpecJ benchmark results. 

The highlights are already given by Josh and Jignesh's blogs: Josh notes the importance of the results in proving the suitability of the Niagara architecture for DB applications and the importance of this result as a proof of SMP scalability. He also notes the significant price difference between Sun and the competition and looks forward to even better SMP performance by PostgreSQL database on Solaris. Jignesh gives some details regarding the DB tuning strategy used. If you want more of the tuning strategy details, you should probably leave him a comment.

Here's a summary of other highlights based on other sources:

• This is the second all open source SPECjAppServer2004 benchmark result and Sun is the only vendor to publish all open source results.
• It demonstrates Sun's commitment to use open source software at all levels of the stack -- including open source databases -- and to bring these price/performance benefits to users.
• An all-Sun, all open source stack comprised of PostgreSQL on Solaris (built off OpenSolaris) on T2000s (with OpenSPARC) with Glassfish gave 89% the performance at 34% the cost of a comparable HP benchmark with proprietary database, application server, and hardware. (Tom Daly provides further details regarding price-performance results.)
  

If you do not know about SpecJ 2004, refer to spec.org. In summary, SPECjAppServer2004 heavily exercises all parts of the underlying infrastructure that make up the application environment, including hardware, JVM software, database software, JDBC drivers, and the system network. The primary metric of the SPECjAppServer2004 benchmark is jAppServer Operations Per Second ("SPECjAppServer2004 JOPS") in either @Standard or @Distributed mode.

Look, also, at Tom Daly's blog for more information on these performance benchmarks and more.

Disclosure Statement:
Sun Fire X4200 (6 chips, 12 cores) 778.14 SPECjAppServer2004 JOPS@Standard.
HP rx2660 (2 chips, 4 cores) 874.61 SPECjAppServer2004 JOPS@Standard.
SPEC, SPECjAppServer reg tm of Standard Performance Evaluation Corporation.
Results from www.spec.org as of 7/10/07.

[ Java ] Soccer {Football} after JavaOne

If you're at JavaOne this week and do not leave San Francisco before Friday night, consider joining me and a few others (from Brazil, Norway, Switzerland, Germany, France, etc.) to play some soccer {football} near the Golden Gate Bridge. It is a great way to have everything you've seen and learned at JavaOne sink in!

I've posted the logistics information on my java.net blog.

[ Java ] Blog Entries on JavaOne 2007

At java.net, I will be compiling some blog entries in anticipation of JavaOne 2007 and following the conference (mostly from the pavilion floor).

For a database related topic, you might want to check out Francois Orsini's "Enabling Offline Web Applications with Java DB," where he previews his upcoming JavaOne talk with Zimbra's Kevin Henrikson.

[ Technology ] Java Stack in Ubuntu

Beginning with Ubuntu 7.04, you get the full Java stack for Linux gathered in one place. I remember learning about Java first on both Solaris (the Sparc stations sitting in the math department at Berkeley) and on Linux (the PCs in a basement office in the industrial engineering department). The tradition continues into "sudo apt-get"! While I'm writing about Java, I should probably remind you about CommunityOne, the free event during this year's JavaOne.

[ Telecommunications ] phoneME Project Moves On

Developing and maintaining software targeted to hundreds of millions if not billions of devices can become a daunting task, and learning to use the tools of trade can be equally challenging.

Fortunately, when tinkering and development is in the open, knowledge--or should I say "know-how"--flourishes.

Developers learn from each other's work, and users can suggest (and make) useful changes. There is something akin to case law here. Unless cases are written and analyzed in a hierarchy of courts by communities of lawyers and judges, other cases cannot be judged and analyzed on the foundation of existing case experience.

Example: Java ME went open source recently under the guise of phoneME Project. Subversion commit messages can be found here. Discussion forums for phoneME Feature and phoneME Advanced can provide useful information. Some good weblogs to check for phoneME and Java ME are those by Hinkmond Wong, Stuart Marks, Terrence Barr, Mark Lam and Darryl Mocek.

[ Java ] Not Just About Diamonds

JavaPolis 2006 proves that Antwerp is not just about the diamond, the ruby, other jewels or gems. It is also about Java and the Java Community. As a starter, you may want to check out Francois Orsini's Hands-on JavaDB (Apache Derby) Lab.

For more, including on the recent, generally-available release of JDK 6, see here.
