Some recent posts showing that your linux box is not secure unless you installed a grub Password.
If you are an administrator of a highly sensitive server, you must do it.
To add a password for grub, first you must generate an md5 password hash using the grub-md5-crypt utility: grub-md5-crypt
The command will ask you to enter a password and offer a resulting hash value as shown below:
Password: (enter new password)
Retype password: (repeat password)
Add the resulting hash value to the file /boot/grub/menu.lst in the following format:
password --md5 $1$s3YiK$M3lxAbqA6JLm2FbDWnClQ0
To require use of the password for entering single user mode, change the value of the lockalternative variable in the file /boot/grub/menu.lst to true, as shown in the following example.

Ubuntu uses nautilus as the default file manager. You can effectively use nautilus to increase your productivity. Here I am telling about a useful hack for power users for opening folders in terminal . See the screen shot below
It allows user to open a selected folder in a terminal window by right clicking on the folder.
For installing "open in terminal" feature you need to install package "nautilus-open-terminal" .
open a terminal
$sudo apt-get install nautilus-open-terminal
or you can use synaptic package manager.
After installing the package you have to logout and login back , Now you can right click on a folder you will get "open in Terminal option.
