How to install Xfce in Ubuntu 12.04

If you want to use less machine resources on Ubuntu 12.04, or if you simply didn't like Gnome 3 layout and usability, here goes a nice tip to you: use the Xfce desktop enviroment. It's lightweight and makes me remember the good old times from Gnome 2 also (this is just a personal opinion).

To install it on Ubuntu 12.04, use the  following command:

sudo apt-get install xfce4

After installation, you are going to be able to choose your desktop enviroment the next time you try to log in.


Another option is to download and install Xubuntu, a Linux operating system based on Ubuntu that comes with Xfce by default.

Linux "nice" command: running a program with modified scheduling priority

There is a very useful program for Linux for setting different priorities to a program: the nice command.
Priority ranges in Linux varies from -20 (greater priority) to 19 (lesser priority). So, the lesser the value, the greater is the scheduling priority.
Use nice is simple. In the example shown bellow, we want to run the program "your_program_name" using priority value 10:

nice -n 10 your_program_name

The default priority value is 0. If you want to set a priority less than 0 (greater priority than the default), you should run it as system root.

How to set line spacing in LaTeX

Some simple (but very important) commands you should know about line spacing in LaTeX:

\singlespacing - sets the text to single line spacing
\onehalfspacing - sets the text to one half spacing
\doublespacing - sets the text to double spacing

To use such commands, you should use the following package: \usepackage{setspace}


Bellow, there's a simple example about how to use these commands:

\onehalfspacing
First part of the text (using one half spacing)
\doublespacing
Second part of the text (using double spacing)
\end{document}
