[UPDATE 18.01.2011]
Finally somebody had the same problem like me and came up with a better solution. The problem with what I wrote: Changes get lost on nautilus updates.

To get the "real deal", stick to Joeys How-To at OMG! ubuntu. Thanks for reading.

[/UPDATE]

to change the side pane colour in nautilus, open the gtkrc file for your theme

e.g.

sudo gedit /usr/share/Ambiance/gtk-2.0/gtkrc

and add

style "treeview-mod"
{  
    GtkTreeView::even_row_color   = "#F2F1F0"
}
widget "*NautilusNavigationWindow*" style "treeview-mod"

only issue: when switching the view to treeview, the background changes, too. But thats not so bad as you mostly use treeview when the folder is full, so that you never see the background in treeview anyway.

I did this with nautilus elementary mod, so I do not know if it fully works with the standard nautilus.

Hello, maybe you study with me here at solent or otherwhere around the world, it does not matter.

Uninetworks tend to be restrictive, unflexible and not workable, especially for IT-Students. So I did/installed/bought some things to make my life a lot easier, maybe you can use some things, too. Maybe not. Just read further.

1. Dropbox

Most Uninetworks have a system to store files and even to download them from home. But otherwise around? Mostly no chance to get files from home to the uninetwork and if you tend to forget or loose your usb-stick that could be bad or worse for your assignments and files.

This is where Dropbox comes in handy. Its syncs the files from your different computers (Windows, Linux, Mac, iPhone, iPad, Android mobiles and Blackberrys) and makes them available for you where ever is an internet-connection and one of the mentioned compatible devices.

Dropbox is nice for making Backups, too. Sharing Files with friends and even a Photogallery can be pubished to your friend, by simply uploading your Photos to a Folder.

Get Dropbox here: http://www.dropbox.com/
Installation-instructions should be very self-explanatory for almost everyone. Btw: You get an Bonus of 250MB on top of your 2GB free account if using my provided link. It means I invited you and I get bonus space, too.

2. Portable Apps

Like said, mostly you will have a uni account, a folder to store files and lots of computers to use, but no rights to install programms. But wait a minute: a folder to store files? That should do it.

http://portableapps.com/ is a site and project, which aims to provide portable versions of many free Open Source Software. You can use them stored on an usb-drive or your uni-account folder, with any Windows PC.

You will find everything you need within the Portable Apps. Favorites like Firefox, Skype, miranda IM (for ICQ, MSN, Jabber and others messenging protocols) as well as a portable Java runtime, notepad++ for syntax highlighting or even a full featured OpenOffice suite, ready to run from your usb-stick or unifolder without the need for installation rights.

3. Get a prepaid sim card with mobile broadband access

Huh? Yeah! If you do not have one, get one. if your mobile is not capable of sharing the internetconnection with other devices, get an u

sudo mv /usr/share/dbus-1/services/org.freedesktop.Notifications.service /usr/share/dbus-1/services/org.freedesktop.Notifications.service.disabled

to turn it on again, just run this
 

sudo mv /usr/share/dbus-1/services/org.freedesktop.Notifications.service.disabled /usr/share/dbus-1/services/org.freedesktop.Notifications.service

Viele Webentwickler kennen, nutzen und schätzen xampp als Entwicklungswebserver.

Die Installationshinweise für Linuxnutzer besagen das Xampp zwingend in den Ordner /opt installiert werden müsse. Das ist erstens ärgerlich, weil man gerne mal vergisst sein /opt Verzeichnis vor einer Neuinstallation zu sichern (vor Dummheit ist niemand gefeit) und zweitens nicht korrekt.

Es gibt ein recht simple Lösung xampp dorthin zu installieren wo man gerne möchte, z.B. ins eigene home-Verzeichnis... Die Lösung heisst Symlink oder auch Symbolischer Link. Man installiert Xampp wohin man will und legt einen Symbolischen Link in /opt, der auf das eigentliche Installationsverzeichnis verweist. Eigentlich ganz einfach. In Konsolenbefehlen sieht das so aus:

1. Xampp wie auf apachefriends.org beschrieben installieren. z.B. In meinem Ordner Programme im Home Verzeichnis.

sudo tar xvfz xampp-linux-1.7.3a.tar.gz -C /home/ich/Programme

2. Einen Symbolischen Link in /opt auf den lampp Ordner erstellen:

sudo ln -s /home/ich/Programme/lampp /opt/lampp

Xampp kann nun wie gewohnt mit /opt/lampp/lampp start gestartet werden und auch alles andere funktioniert wie bisher.

Plus: Wenn ich nun mein Homeverzeichnis sichere, ist auch mein xampp mitsammt Document Root und Datenbanken gesichert.

Achtung: Wird der Symlink leichtsinnig gelöscht, wird auch xampp gelöscht. Ein Symbolischer Link ist nicht equivalent zu einer WIndows-Verknüpfung.
