I recently encountered two problems, one of which is a GNOME problem and the other a Firefox problem.
The Gnome Problem occurs when the user logs on and an error pops up stating a problem with GNOME TrashApplet. To fix this problem, start Synaptic from the Terminal
synaptic
and then lookup trash. Look for the gnome package from the search result, mark it, and then generate a script for the download you marked. Run the script, which will wget the gnome package, and then open the package to reinstall. This, I believe, fixed the problem.
The Firefox problem was that Firefox would simply not load. It stated that there was already a Firefox session in progress. This could be due to a corrupted upgrade in Firefox (which could be caused by an abrupt stop in the Firefox upgrade process). To fix this problem, type into the terminal
mv ~/.mozilla/firefox ~/.mozilla/firefox.old
This will move the broken firefox to ~/.mozilla/firefox.old. At this point all you need to do is start Firefox and it should work like brand-spankin' new.

Installation of Eclipse
Some information about Eclipse:
Dave wants to use Eclipse Galileo, which can be downloaded from here.
Once you download the file, extract it with the Unix command
tar xzf [DIRECTORY]/eclipse-cpp-galileo-SR2-linux-gtk-x86_64.tar.gz
where [DIRECTORY] should be replaced with the directory that the download was saved in. At this point, I moved the extracted directory (should be, by default, named "eclipse") to /usr/local by using the command
mv eclipse /usr/local/eclipse3.5
in the directory where the extracted directory is stored. Notice that this command also renames the moved folder to "eclipse3.5".
Finally, to allow eclipse to be run at the command line, I went to the /usr/local/bin directory, and performed
ln -s /usr/local/eclipse3.5/eclipse eclipse
which creates an alias in the bin directory.
If you run into permission problems, put a sudo in front of the command you are typing.
In order to install Java and Pydev, I just added them under Help->Install New Software and choosing "All Available Sites" under "Work with:". They can be found by scrolling down the list generated after changing "Work with:".
To distribute the eclipse configurations across all of the machines, I used rsync to copy the eclipse folder to the same place on each machine, and then I created an alias to the program in /usr/local/bin so that eclipse may be run from the command line.
