mardi mai 15, 2007 NASA WorldWind on JRuby
I am preparing a few demos for our local 'JavaOne AfterGlow'. Here is a quick one that need JRuby (I took NB6 M9 preview) and the WorldWind Java SDK. Note that it is also my first JRuby attempt! Make sure the WorldWind jars (worldwind.jar, jogl.jar & gluegen-rt.jar) are in the classpath.
#WorldWind.rb
include Java
import javax.swing.JFrame
require 'worldwind.jar'
include_class 'gov.nasa.worldwind.BasicModel'
include_class 'gov.nasa.worldwind.awt.WorldWindowGLCanvas'
frame = JFrame.new("WorldWind on JRuby")
frame.set_size(800, 600)
wwind = WorldWindowGLCanvas.new
wwind.setModel(BasicModel.new)
frame.add(wwind)
frame.show

mardi juin 06, 2006 JavaOne Afterglow in Brussels
This Tuesday (8th of June), Sun Belgium will host a JavaOne AfterGlow. I'll be joined by Geert Bevin (Rife) and Stijn Van Den Enden. During the afternoon, we will go over some of the annoucements of JavaOne, the hot topics like Java EE 5, Dynamic (Type) Language, Semplice, Ajax, etc. There will also be a specific discussion on Continuation Currently, most of the demos we will do seems to work!
To accomodate more people, the event has been moved to the Sofitel (Diegem near the Airport). This event is free and everybody is welcome, just make sure to register.

lundi octobre 31, 2005 Dtrace & Java - now in Mustang b58!
If you have been using DTrace on on the early builds of Java SE 6 (Mustang) on Solaris 10/Open Solaris on Sparc platform; you know that you had to do your own build of the JVM. The reason is simple, Solaris 8 is still the official build platform of Java SE on Solaris/Sparc. Building the JVM is not hard once your build environment is correctly configured. But building Mustang every weeks, from the updated source tree, just to enable Dtrace probes takes times! The good news is that since last build (b58), you can now use DTrace on the 'regular' Sparc Mustang build downloaded from java.net. No need to do your own build anywmore just to enable the DTrace probes! To test this, just do adtrace ---l | grep hotspot or dtrace -l | grep jni while the JVM (Mustang build 58 min.) is running, and you'll get +500 DTraces probes.

It tooks a little longer than expected but the JavaOne Technical Sessions (including audio and syncronized transcript) have been posted here on Sun Developer Network. It is free for any SDN member (free registration)! Tag: JavaOne ( oct. 17 2005, 12:40:42 PM PDT ) Permalink Comments [0]
lundi octobre 10, 2005 Free (4 days!) Application Performance Tuning seminar!
Next week, Sun will hold a free 4 days(!) seminar on application performance tuning at the Interuniversity Scientific Computing Facility. The location will be the Notre-dame De Namur University, that's the one in Belgium, not the one on the 101 south SF
The seminar will focus on serial program tuning, tuning shared and distributed memory parallel applications using automatic parallelization, OpenMP resp. MPI... The seminar will also cover the available tools in details (Sun Studio, Performance Analyzer, Sun HPC ClusterTools environment... ). And last but not least, the agenda has some hands-on labs as well!!
The complete agenda for the 4 days including registration details can be found here. Again, this is a free seminar but seating is limited!

mercredi octobre 05, 2005 Rick Ross and GlassFish, better late than never!
JavaLobby's Rick Ross finaly got it! GlassFish aka Sun Java System Application Server 9 Platform Edition is an Open Source application server that will be fully compatible with the Java EE 5 specification! Here is a (nice) abstract of Rick Ross editorial from this week JL's newsletter (their legal fine print allow me to share it with my friends!). People who swim with Glass Fishes don't fear the sharks Okay, okay, so perhaps I am a little bit slow to catch on. Sun did something absolutely HUGE at JavaOne, but I missed the significance of it, and I may not be the only one who did. What did they do, you ask? They placed the entire source code from which they build Java Enterprise Edition (Java EE) under an OSI-approved open source license called the Common Development and Distribution License (CDDL.) That's right, they open sourced the foundation code from which all J2EE is built! I vaguely remember sitting in one of the keynotes and hearing that Sun was open sourcing their app server, which didn't really seem like such big news. What I overlooked is the minor fact that this includes the source code for the Reference Implementation of Java EE (the new moniker of J2EE, kinda like Puff Daddy, P. Diddy, Diddy.) You can download the whole thing from CVS on java.net right now it's called Project GlassFish, and I now realize it was probably the biggest thing that happened at JavaOne. The source code of Java EE is now genuinely open, how did I miss that!? Kudos to Sun for taking this big step. Well done! I guess it wasn't said clearly enough at JavaOne and afterwards through blogs and so on?! Anyway, it is better late than never. It is also great that people like Rick Ross are starting to pass, to the community, the message about GlassFish! Oh and by the way, I have also heard that some people were confused and mixing GlassFish and Looking Glass, 2 different Open Sources projects from Sun that only have Java and a Glass in common!

Did you notice ? The internet has been restructured! I got the following message while searching for some technical information...
samedi août 27, 2005 New forum for Dtrace / Java discussions
Kelly O-Hair has just started a new forum on java.net for Dtrace discussions related to Java. The forum covers the DVM approach and the Mustang (JDK 6) Dtrace support. Kelly's first posts cover FAQs about this topic. Tags: Dtrace Java ( août 27 2005, 09:45:30 PM PDT ) Permalink Comments [0]
jeudi août 18, 2005 Zotbot impact : 100 cars!!
I've just heard on TV that the Opel factory (GM Belgium) was hit by a variant of the Zotob worm. As a consequence, the production chain was stopped during two hours and 2 hours is 100 cars!! Other companies were affected as well. See also here (Dutch). Tags: Worm Virus Zotob ( août 18 2005, 01:35:13 PM PDT ) Permalink Comments [0]
mercredi août 17, 2005 Hard disk and consumer device
Since a year, I am using a Digital Set-Top box (DVB-S) with a built-in PVR. I think I won't be able to live without the PVR... Well, I would be able to live without, but I won't be able to watch TV anymore without a PVR! Time-shift is just so convenient! It is on all the time! Being able to pause or rewind a live TV program is just great. The pure recorder functionality is also way better than traditional recording (no more juggling with tapes, no more waiting to rewind tape, no more crappy VHS low quality, etc). My only concern is the ambient "noises" produced by the STB hard disk! There are always some subtle "ttrrr" (head movements) and some "zssszzsss" (disk spinning) polluting noises! The bothering level directly depends of the program I am watching: almost null for an action movie, acceptable for a TV movie, annoying for a suspense movie! I am not a die-hard audiophile, but the noise is there,subtle but present! So that is annoying! And of course, once you have noticed this... well, you'll concentrate to make sure you hear those annoying noises; just to check that they have unfortunately not disappeared!
I have replaced the original HD with a more silent one. It is already better. But noise factor is not really a feature for hard disk! The other issue is that I need IDE HD, and IDE disks are scarce those days!

mercredi août 03, 2005 a NetBeans champion...
Yesterday, Vincent Brabant, one of the NetBeans champions (right on the picture), got the 1st part of his award. He still nedd to receive the rest of his award, the geeky part... Another nice touch from James (the workstation is James's idea!) in the pack was this year J1 T-shirt. Bravo encore Vincent!
