nautilus-open-terminal runs on Gnome Windows manager and it allows you to right click in your file manager
and open up your terminal in the current folder. Clearly a very useful tool.
It used to be installed as a default application in many distributions but for some reason it was left out of Fedora 11
To add it back in simply type
sudo yum install nautilus-open-terminal
If it somehow got left out of your Ubuntu installation, then type
sudo apt-get install nautilus-open-terminal
You will need to restart your Gnome session to activate it.

Good, easy way to clone a hard drive.
dd which is used for converting and copying files, can be used as a powerful and simple image cloning application.
dd if=/dev/hda of=/dev/hdb
if you want to see your progress
then type in another terminal
kill -SIGUSR1 xxxx
were xxxx is the process ID of the running dd process
and the progress will report on the original terminal that you started your cloning operation on.

you have 3 PC's on your Desk. One running Linux , One running MAC OS and the other running Windows XP.
all 3 with their own Monitor .
wouldn't it be cool, to be able to use the same Mouse and keyboard for all 3 PC's. and to be able to copy and paste, Text, Images and HTML content between the PC's.
No Problem, (drum roll...) ... in steps Synergy.
Synergy lets you share a single mouse and keyboard between multiple computers with different operating systems, each with its own display.
Redirecting the mouse and keyboard is as simple as moving the mouse off the edge of your screen. Synergy also merges the clipboards of all the systems into one, allowing you to cut-and-paste between systems. it also synchronizes screen savers so they all start and stop together.
Synergy uses TCPIP to communicate mouse position and keyboard keystrokes between the PC's. So all you need for Synergy to work is to have your PC's connected to the same network. (No additional hard ware is required)
you can download synergy from http://synergy2.sourceforge.net/
