Check out this article Paul Tyma (Mailinator) which shows better performance using old-skool java.io instead of the async java.nio, thanks to native threading libs (like NPST on linux).

The Google’s Open Source Blog announced Google CL, a tool that allows you to use Google services from command-line. They provide commands to work with Blogs, Calendar, Docs, Picasa, contacts and YouTube.
A while back I was messing around with GData java-client, but with command-line access it’s even easier to use googles services in my own little projects…

Check out project Panopticlick, they are investigating how a browser can create a unique fingerprint which enables users to be tracked, even with cookies disables or deleted… They also provide some tips to minimize the uniqueness of your browser.
My browser is estimated to have a fingerprint that conveys at least 16.08 bits of identifying information.

I’ve discovered yet another -maybe quite useless- trick to combine java-development, JBoss AS and Ubuntu (or any other debian-based distro).
I created a very simple log4j-appender which used notify-send (commandline-tool for libnotify) to report errors. This way I will get a visual notification when something went wrong, immediately showing the class of the error and the message.
As an example, I use my favorite Application Server, JBoss AS, but any java-app using log4j (or commons-logging on top of log4j or slf4j-log4j) will do.

Everyone knows them I guess, the famfamfam silk-icons set. Completely free of charge and they look great! Mark James also created a set of flags (using ISO-3391-2), these can be found here.
When I was using the flags in an app, I noticed that (accoring to the XML’s I downloaded from iso.org containing all country-data) 5 flags where missing. One was Antarctica, but makes sense since it has no official flags. The other I created myself, trying to use the same “style” as the original ones, see below:
: Antarctica (AQ)
: Guersney (GG)
: Saint Barthélemy (BL)
: Saint-Matrin (MF)
: Jersey (JE)
: Isle of Man (IM)
Feel free to use these (was only 10 minutes of work anyway…):

Here’s an easy way to create a notification from inside eclipse (triggered by your own plugin), without any effort at all. MyLyn-core has a nice popup that looks great cross-platform, fades out and is visible outside the eclipse IDE, even when minimised (and also cross-desktop on ubuntu).

While upgrading to Karmic Koala (Ubuntu 9.10), my JBoss Tools eclipse plugins suite stopped working. Workspace log told me:
java.lang.UnsatisfiedLinkError: /opt/eclipse/plugins/org.mozilla.xulrunner.gtk.linux.x86_1.8.1.3-20070904/xulrunner/libjavaxpcomglue.so: libstdc++.so.5: cannot open shared object file: No such file or directory

XULRunner needs libstdc++5 and it seems that it’s removed from the Karmic repository when upgrading from Jaunty. To get JBoss Tools back online, install the .deb file yourself from the jaunty repo:

De mannen van Microsoft krijgen ook alles geregeld, zolang het maar geld opbrengt…Onbegrijpelijk waarop ze nu weer een patent hebben gekregen:
A word processor including a native XML file format is provided. The well formed XML file fully represents the word-processor document, and fully supports 100% of word-processor’s rich formatting. There are no feature losses when saving the word-processor documents as XML. A published XSD file defines all the rules behind the word-processor’s XML file format. Hints may be provided within the XML associated files providing applications that understand XML a shortcut to understanding some of the features provided by the word-processor. The word-processing document is stored in a single XML file. Additionally, manipulation of word-processing documents may be done on computing devices that do not include the word-processor itself.

Er is een bug in Traffide 0.0.2 geslopen (Buggy Bison)… Bij het gebruiken van een proxy-server die authenticatie vereist, werkt Traffide niet.In de method be.stacktrace.traffide.http.HostConfigurationWrapper:getHttpState staat:
newState.setCredentials(AuthScope.ANY, state.getCredentials(AuthScope.ANY));
Even te kort door de bocht… Commons-httpclient veralgemeent authenticatie zodat de method-signatures van setCrendentials() en setProxyCredentials() exact dezelfde is.
Gefixed op de update-site. Als je de laatste versie (0.0.2) al hebt geinstalleerd, gaat eclipse deze fix niet binnenhalen. Best gewoon de jar manueel downloaden en in “/eclipse/plugin/” kopieren!

Het duurde wat langer dan verwacht, maar hij is er “Traffide Buggy Bison”.
