This Eclipse problem in Linux environment has been solved. The original Eclipse I installed does not have JDK, and I installed it through Eclipse plugin management. So, the previous project folder I created won’t work unless recreate a “java project.” In java project folder, the layout is created by eclipse automatically. And then, everything is just working flawlessly!
Almost all of gnome dark themes influence the Mozilla Firefox’s accessibility, such as black menu bar with dark fonts, white search field with white font. It can be fix by a good web design approach, but not many web designers can be so considerate. Besides, it’s always better to fix problem permanently.
To customize the firefox for accessibility purpose, u would have to create a css file “userChrome.css” in your home folder “~/.mozilla/firefox/*.default/chrome/”
In the folder, there are 2 sample userContent.css files for reference. My own userChrome.css is like:
menubar, menubutton, menulist, menu, menuitem {
font-family: Matrix !important;
font-size: 3mm !important;
color: #666666!important;
}
menupopup > *{
color: #000000 !important;
}
At least it works for me.

It works flawlessly. If there is no Emerald Theme Manager come with the package, DON’T MISS OUT! Search google and get one!
Here are some my desktop screenshots with Compiz-Fusion & Emerald theme installed:
Conky is a desktop system monitor application. Eh… I installed it, and it works great… however, I found out that I don’t actually need it… Whatever, for the sake of its existence, here is the tutorial from CraigWatson.
Installing & Configuring Conky
To get conky up and running, just type into a terminal:
sudo yum install conky
Then create your .conkyrc file and paste in the contents (you can either use mine as a starting point or some of these:
gedit ~/.conkyrc
After that, you need to create a script to load Conky after any running window managers (e.g. Compiz) so that it integrates nicely:
nano ~/.conkyscript.sh
Either copy/paste or type this:
#!/bin/bash sleep 10 && conky;
Then make it executable and add it to your GNOME session:
chmod a+x ~/.conkyscript.sh
System –> Preferences –> Personal –> Sessions –> Add
Name: Conky
Command: ~/.conkyscript.sh
(you may need to put the full path to the script - e.g. /home/user/.conkyscript.sh)
This is a sample .conkyrc file which I modified base on CraigWatson’s original file:

This is my screenshot for conky:
VMware Server is an application that let you create many virtual machines on your own machine. It is highly effective and extremely useful for server and academic purpose. I use it for messing around the operating systems which is too dangerous to test out on my computer.
Here is a link to the tutorial of “How To Install VMware Server.”
The usage of this application is quite straight forward.
With VLC Player and Realplayer installed on your linux, pretty much any format of video/audio can be played on your computer.
Install VLC Player on Fedora (Tutorial)
Install VLC Skin by following Jonny’s guide:
1. Go to VLC skin website and download the skin your like: http://www.videolan.org/vlc/skins.php
2. Copy your new skin/skins to your /usr/share/vlc/skins2/ directory by doing following:
- login use “su” and type password
- type (WMP11.vlt is the skin’s name):
cp /home/yourname/WMP11.vlt /usr/share/vlc/skins2/
3. The next part is easy once you know what you are doing. Click on the menu Settings>Preferences>Interface>Main Interfaces
Now in the ‘Interface module’ box scroll down and click ‘Skinnable Interface’. Hit the save button and restart VLC.
4. A new interface will appear. Now right click on the bottom right hand corner of the new interface/skin and a menu will appear. Scroll down and choose ’select skin’ and click on your choice of skin.
5. When you have decided on a new default skin, go to >Preferences>Interface>Main Interfaces>Skins
and tick the advance options box, and the skin you are currently using will now be listed. In my case
/usr/share/vlc/skins2/WMP11.vlt is the skin i’m using. Hit the save button and restart VLC. Note there is an option to reset your default skin if you have any problems. That’s it!
Fedora 9 just released it’s official version. The improvements are KDE 4, GNOME 2.2, Firefox 3, flexible installation partitioner, and some better interface & security features. I have tested it myself, and here are some problem I have encountered:
1. NVIDIA driver couldn’t install or find a place to install its required kernel.
2. Freeze… The screen freezes after establishing a connection to internet.
3. Updating software no respond - GUI of package upgrading software literally useless… but “yum update” works.
I tried both update from F8 to F9, and a fresh installation. Although both methods worked, none of them gave me a satisfied result. So, I reinstalled F8 and probably will stick to it until the problems are fixed in Fedora 9.
Actually, it’s probably a good idea that to upgrade os from F8 to F9 when they release F10…
I have used both VirtualBox and VMware Player. Well, VirtualBox definitely faster and more stable than vmware so far… The only problem right not is VirtualBox does not support FreeBSD and its related operating systems (Maybe there is a solution, but I just can’t find it…). Anyway, VirtualBox is GPL, so it’s great.
You can obtain VirtualBox here: http://www.virtualbox.org/wiki/Downloads
Public Folder If you want to create a public folder between host and guest machine, you have to install Guest Additions on your guest machine use VBoxGuestAdditions.iso. (location folder in F8: /usr/share/virtualbox/VBoxGuestAdditions.iso) The guide is quiet well documented, I’m not gonna talk about how to establish a network with public folder.
USB Device Another issue is USB device in guest machine doesn’t work. The specific solution for this problem in F8 can be found in this article “USB Fix for VirtualBox on Fedora 8 Host.” The simplified procedure:
usb:x:503:username” (503 is group number). If not, add one line as such. Group number is unique for each group. none /sys/bus/usb/drivers usbfs devgid=503,devmode=664 0 0
503 is the group number.
I currently have Windows XP pro and Solaris run on my host machine. They are great!
