Listen to What the Man Said

Posse audio from our JavaOne booth

I was over in the mini-talk audience area when I first noticed that the Java Posse guys had stopped by the java.net booth at JavaOne, complete with recording gear. "What's up with that?" I wondered.

Now we know. It turns out that they combed the pavilion floor a few times, grabbing people they knew or wanted to know and chatting about the show, the stuff on display, the various projects people were working on, etc. Edited together, it seems a pretty random mix, as they go from talking about IDE's to ME to robots to Flash, etc. But that's pretty much the impression that anyone gets from walking the pavilion floor at JavaOne... there's just that much going on. If code obfucators aren't your thing, look across the aisle and you'll probably see something completely different: object databases, Blu-Ray players, code coverage tools, etc.

So we kick off the Java Today section with the two podcasts they've released of their JavaOne Pavilion walkabouts. In Java Posse #129 - Walking around JavaOne 2007, Part 1, they stop by the java.net booth and talk with Aaron Houston, Paul Webber, Mike Van Riper, Chris Maki, Felipe Gaucho, and Michael Hutterman about JUG's and Java Champions. In Java Posse #131 - Walking Around JavaOne 2007, Part 2, Posse member Joe Nuxoll returns to the booth to talk with Robotics Community leader Bruce Boyes and Eric Arceneaux about SunSpots, TrackBots, and other Java-based robotics technologies.

In XQuery Java API JSR 225 Available for Public Review, InfoQ reports "the first public review draft of JSR 225: XQuery API for Java has been posted for review. The spec (being led by Oracle) aims to provide standard programmatic access for XQuery implementations in Java. XQJ is a generic XQuery data access framework, which provides a uniform interface on top of a variety of different XQuery implementations." The article goes on to cover early feedback from industry experts and related JSRs.

A recent interview on 360Mobile.us, Martin Brehovsky - SVG and NetBeans, features a discussion of mobile tools in NetBeans and support for JSR-226 SVG in mobile devices. Martin, an engineer on the NetBeans mobility team, says "the coolest thing about SVG is not the fact it is vector, but the fact it is interactive and animated, so one can create very flashy UI with it. A great thing also is the graphics can be designed in designer's tools like Adobe Illustrator or Ikivo Animator and then brought to the NetBeans IDE and used in the visual designer."

Speaking of conferences, today's Weblogs feature two blogs with wrap-ups and reminisces of Jazoon '07. Fabrizio Giudici starts with My numbers about Jazoon: "Summing up, a good starter from my perspective. I personally enjoyed my stay at the conference and I came back with a high degree of satisfaction. And it's good to have another good conference not so far from home. I hope I'll be back next year."

Next, Harold Carr offers My Jazoon Report: "I presented Tango at Jazoon in Zurich, Switzerland last week. Here's my trip report."

Meanwhile, Osvaldo Pinali Doederlein reports that Sun JDK 6.0u2 is available. "Sun JDK 6.0 Update 2 is available. This is a massive update with 182 fixes and enhancements, including a few performance optimizations that allowed Sun to recover the SPECjbb2005 nonclustered record as reported by David Dagastine."

Today's Forums section begins with an atypically sophisticated Beginner Question from luft: "In order to learn the language I have decided to work on a fun project with no real world usefulness. I want to create a map generator to generate terrain data. I wanted to use a random number generator like Util.Random that accepts a seed number so that the map could be reliably reproduced simply by knowing the seed value. This is so that large map sectors could be regenerated when needed thus saving huge amounts of disk space. I got to thinking however that if future versions of Random produce different numbers my map generator wouldn't be very good. Is this a likely problem or are the numbers generated for a particular seed pretty reliable going into the future. What about on different platforms?"

kleopatra reports a SwingX update in Re: [FYI] Highlighter overhaul starting ... "Just fixed a long-standing task - implement ui-specific highlighters cleanly. Until now, the UIColorHighlighter got the striping background from an internal hardcoded map, a quick&dirty implementation based on the work of our visual designer, Coleen (her color table is accessible from the highlighter wiki pages). The mapping is done (same as before) only for a handful of the most common LFs, not quite sure what's the best approach to allow third party LF colors be easily installed. Could any of the LF gurus please have a look at the code and my comments? Now I changed that to load in a UIColorHighlighterAddon - the colors are the same, except for maybe c&p errors - so please let me know if you experience any new trouble."

Finally, jwenting tries to dispel some very crusty Java stereotypes in Re: Develop in Java or not? "Java hasn't been "slow" for years. And for most desktop purposes "slow" is irrelevant anyway, as they spend most of their time waiting for user input. If a user takes 10 seconds to enter data before pressing a button to get it processed it hardly matter whether that processing takes 10 milliseconds or 20, and the difference between Java and C++ is often smaller than that. The main problem with Java on the desktop is the poor quality of the code most programmers produce, leading to applications that are sluggish due to no fault of the language itself."
