mystery

The most simple answer to explain any unexplained occasions or unexplained things
Use that if someone ask about something that I don't quiet understand
Use that if someone ask about something that I won't them to know about

the answer that will you get if you ask me about Proxy and Reflections on Java
you can't hardly hear that words if you ask about my live, but really that's actually the word

my gnome empty desktop (on etch debian)

Today my gnome with it sweet compiz-fusion got error message when I came back from lunch. I thought it was like usual (something move the mouse wheb at the same time gnome lock the screen. Some applications interface are grayed). But when i restart the desktop (Ctrl+Alt+Backspace) still I got the menu bar and other applications except nautilus file browser, also my desktop is blank (no wallpaper neither icons).

I got my desktop back after i remove all my home settings which related to gnome and nautilus and than run these commands:

• dpkg-reconfigure gdm
• dpkg-reconfigure gnome-desktop-data
• dpkg-reconfigure gnome-control-center
• dpkg-reconfigure gnome-menus
• dpkg-reconfigure gnome-system-tools
• dpkg-reconfigure gnome-applets
• dpkg-reconfigure gnome-session

But still after running a while I got that error again. After all of those unsatisfied result I remove all my gnome and xserver-xorg

• apt-get remoce xserver-xorg --purge
• apt-get remove gnome gnome-utils gnome-core gnome-desktop-data gnome-desktop-environment
• apt-get remove --purge gnome gnome-core gnome-destop-environment
• aptitude purge gnome gnome-core gnome-destop-environment <<>

another command to remove all gnome related packaga are:
apt-get remove gnome*

after all package removed than reinstall gnome with this command:
apt-get install gnome-destop-environment

since than i got my gnome back....

I also got another cool package: gnome-fifth-toe

my java and python

From the code writing perspectives, java is more annoying than python (much more). But till now application which written on java got more appreciation than the others, even they gave the same result. Is that just because writing on java is more difficult?? :)

Because of that difficulties than came jython and groovy which seems very interesting. Jython is pure python written on java which ofcourse got full access to all java class libraries (accessing java class libraries with that simple python style, wow that was ammazing). Than groovy is the different things which gave simplecity of java with their red and blue side. The red side is they offer simpler method for writing java code, and the blue code just offer different perspectives about java (much more different but also much more fun because it's simplicity). Both 'languange' (jython and groovy) in advance could be compiled to java class. and both gives interactive shell.

But still when I check to the java development site I got that they only suggest those languge for prototyping. Do I need to learn jython or groovy??? or I just need to learn python and/or java, and than glue them together. Or I can stand only on one of them; since all of them provide their own library, framework, fans, etc.

Oh I forget one more things, ruby with it fomous web framework ruby on rails. They also as simple as python also with java support on jRuby and bundeled ruby on rail web development on current netbeans version. But don't know yet RoR framework performance on high scalability site.

my Linux and Nvidia driver

Currently on my PC I got Debian etch4, openSUSE 11 and centOS 5.2. I just reformat my whole hard drives after I got failed to perform filesystem check on mounted system (sound stupid isn't it?, but while perform that process suddenly my electricity down, so that's make it worse).

I write this post just for keep my remember not to install nvidia video driver from those distro repository (event form openSUSE's one click solution) bacause I always got failed when install compiz-fusion based on that driver. So make sure always use driver that dowloaded from nvidia site.
But i know they have do their best to make it, and it must be happen one time
thanks to everyone that help me to make my Linux desktop seems beautiful

my internet radio

Today I just installed shoutcast server. Like before, actually it's easy to setting shoutcast. One thing that make it's seem hard is no clear description from documentation about what next to do. Because after I run the configured server and go to the admin page I got the page with status that server is currently down. But it's OK...
here's the video about shoutcast server installation
The problem solved after install shoutcast DSP plugin on winam (for Microsoft windows) or xmms (for window or linux) and configure the setting. For detail about DSP installation refer to this page: http://www.shoutcast.com/download/broadcast.phtml
Here's another vidoe about shoutcast installation: Another tool for making media stream server is by using icecast. Seems, icecast offer more advance option and planed to support more media file types.

my Openbravo on etch4 debian

Install latest apache ant, java SDK (1.6) and postgresql-8.3 get latest java SDK and postgresql-8.3 from backports by add this line on /etc/apt/sources.list:deb http://www.backports.org/debian etch-backports main contrib non-free Before installing postgresql-8.3 I need to remove my older postgresql-common since befor I use default install postgres (7.4). Than install again postgresql-common using specified repository because without that option I still got the old version, event the new version alredy listed. Use this command to intall postgresql-common from backport: apt-get install -t etch-backports postgresql-common and than install postgresql-8.3 tomcat and java SDK like usual: apt-get install postgresql-8.3 sun-java6-jdk tomcat5.5 tomcat5.5-admin tomcat5.5-webapps Than follow Openbravo environment installation After all above steps I still couldn't got my openbravo login page. but it solved with this command: /usr/share/tomcat5.5/bin/catalina.sh run I didn't know what was hapened, but it's worked
