[ Java ] User Has It Right! ....

Kristian Waagan (of Sun's Java DB development team) has really given Java DB (Sun's distribution of Apache / Derby) a new life of its own when it comes to handling CLOBs, starting with Java DB 10.5.

Check out this thread. 

Note the following testimony from David Goulden:

The performance improvements with CLOBs are dramatic. I created a record with a CLOB containing about 10 million characters using derby 10.4. The following query took over 6(!) minutes:

       SELECT CONTENT FROM MESSAGES WHERE ID = 1

(CONTENT is the CLOB column.)

I then installed derby 10.5 and did a soft upgrade. The same query now takes less than three seconds!

[ Java ] JavaDB 10.5.1.1

Now, a new release of Apache/Derby is out.

Francois Orsini has a more detailed note on this. It is great to see that many of the features listed are developed by our small but amazing team of Java DB engineers.

(See my previous post about this cauldron where Java DB is forged!)

[ 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.

[ 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.

[ Java ] A simple Applet for Game of 15

If your browser has a proper Java SE 1.5 plug-in, you can find the simple Applet here.

For more on Game of 15, you can look here.

The game is often listed among the well-known NP-Complete problems.

[ Java ] JavaOne is better than ever

Given my impressions from the first day of JavaOne 2006, I believe JavaOne is now far better organized, more effective and with greater substance than the ones I ones I attended and spoke at in 1999, 2000, 2001 and 2002. Perhaps, the trouble was that in these other JavaOne's I was a speaker. When you're a speaker at JavaOne, you become a bit too focused on your own talk and forget that there are other things going on, too.

In any case, I can sense a very significant improvement, and it has to do, I think, with Sun's diligent work to collect and use feedback from the attendees, greater involvement of the engineers in the organizing and refereeing committees and a general raising of awareness regarding audience expectations. People like Sreeram Duvur, Bill Shannon, Graham Hamilton, Eduardo Pelegri-Llopart, and countless others, including excellent engineering teams such as Ludo Champenois, Jerome Dochez and Roberto Chinnici, who have contributed and paid a great deal of attention to details that make the conference a really useful one for developers.

On this first day, there was a very good reception of the Derby talk given by Dan Debrunner and David Van Couvering (May 16, 2006). People asked some good questions regarding XML support (the person raising this question was invited to join and contribute to the Apache / Derby community), the timing of recovery (does it happen at the time next connection is opened? earlier? later?), performance compared to other databases, etc. People seemed to be using Derby or thinking of it.

The Derby evening event put together by Sun and IBM, Tuesday night (May 16, 2006), was also well-attended. People seemed more interested in the conversations than in the food, which was also very good, or the drink. For our parts, it was a great opportunity for our visiting, Trondheim, Norway engineering team to meet and mingle with other Derby contributors.

[ Java ] Concurrent Programming w/ java.util.concurrent

Concurrent programming with Java has entered a new era with the java.util.concurrent libraries.

What we used to build, painstakingly, is now before us to use.

One of the sessions at JavaOne 2006 was devoted to this library.

I've written about this session in much greater detail on my java.net weblog.

[ Java ] 12 Days to JavaOne

At the time I write this, only 12 days are left to JavaOne 2006. (I've also blogged about it, here, in anticipation.)

Getting active and browsing through the forums seems like a good way to see what concerns people in each of the large categories of Java technologies.
