If you ever wanted to create an ISO file, you don’t need additional software or any power skill under Ubuntu. You can either create an ISO of an optical drive (e.g. CD, DVD) or a bunch of folders .
If you want to create an ISO file of a folder just type this is a terminal:
mkisofs -r -o file.iso /folder/
If you want to create an ISO file off of CD/DVD:
dd if=/dev/cdrom of=file.iso bs=1024
BE CAREFUL!!
dd (aka Data Destroyer) can cause serious data loss if you don’t be careful when writing if (input file) , of (output file) locations you will lose data.
That’s it
Enjoy
For some reason, if you can’t get backspace button to navigate back in Firefox, here’s a fix for it:
Open up your firefox and type
about:config
in the address awesome bar. Click “I’ll be carefull, I promise” if it asks. Then in the filter bar type:
browser.backspace_action
You don’t need to type it all. It’ll show you the this entry if you type some of the first letters. Probably it has a value like “2″ Double click the item and change it’s value to 0 (zero).
That’s it. You don’t even have to restart your browser.
Have fun.
Firefox is an awesome browser. It’s even more than that with the awesome bar. But did you know your whole web history, bookmarks (and also some more info) are stored in sqlite databases? This means it’s more stable than standart DOM Storage but has less performance if it gets too many changes in a short period.
But fear not. Just like on your website, you can optimize your databases in Firefox. Under ubuntu you have to install sqlite3 from repository:
sudo apt-get install sqlite3
Then just run this command to Vacuum your databases under your firefox profile folder.
(It’s harmless but make a backup of your profile folder, in case of…life)
find $HOME/.mozilla/ \( -name "*.sqlite" \) -exec sqlite3 {} "vacuum" \;

If you have deleted some of your panels by mistake or on purpose (e.g. trying out some dock panels like “awn”) there’s a way to revert them back to the initial form that they were in , as in a fresh ubuntu installation.
Open up a terminal window and type the following lines:
gconftool-2 --shutdown
rm -rf ~/.gconf/apps/panel
pkill gnome-panel
That’s it. Enjoy it!!!

There’s a fantastic article on Ubuntu Community Help site about installing Google Earth on Ubuntu. I personally recommend installing by a package. That way it will be a little harder but uninstalling will work like a charm. Here’s the link to the article:
