For those who don't know about morse code should read it about it from Wikipedia. Army, Pilot and Airtraffic Controllers are basically familiar with the morse code but even a normal person can learn it. It is kinda foreign english language and can maybe come in handy in remote situation for sending distress signal.

You can learn Morse Code from various websites like this one http://www.learnmorsecode.com/

It is a good language to learn it as a hobby and the best part is it is used only in English so even the Chinese or the Russions or the Arabs will talk to you in English if they are talking in Morse Code.

To install morse code in the terminal go to http://morseall.org/ and download the .deb file for Ubuntu and Debian and install it.
After installing Morseall you can start the morseall program by typing morseall in the terminal

In one of my previous posts I have written about "nautilus-open-terminal" which let you open terminal wherever you want but there are many other Nautilus addons which can make our life a little bit easy. They are Nautilus-Image-Converter, Nautilus-Wallpaper and Nautilus-Actions.

Nautilus-Image-Converter : This package adds a "Resize Images..." menu item to the context menu of all images. This opens a dialog where you set the desired image size and file name. A click on "Resize" finally resizes the image(s) using ImageMagick's convert tool.

To install it just issue this command in the terminal "sudo apt-get install nautilus-image-converter"

Nautilus-Wallpaper : This is my favourite addon. nautilus-wallpaper is a Nautilus extension that adds the ability to set your desktop wallpaper from the context menu. Just right-click on your selected image and select "Set as Wallpaper" from the menu.

To install it just issue this command in the terminal "sudo apt-get install nautilus-wallpaper"

Nautilus-Actions : Nautilus-actions is an extensions for nautilus which allow to add arbitrary program to launch through the nautilus popup menu of selected files.

It allows you to define custom action or commands for certain types of files or files with names matching your description. Each time you right-click on one or several selected files in nautilus, nautilus-actions will look at its configured actions to see if a program has been setup for this selection. If it is the case, it will add an item in the menu that allow you to execute the program on the selected files.

To install it just issue this command in the terminal "sudo apt-get install nautilus-actions"

Enjoy!

Bootchart is a tool for performance analysis and visualization of the Linux boot process. Resource utilization and process information are collected during the boot process and are later rendered in a PNG, SVG or EPS encoded chart.

Bootchart provides a shell script to be run by the kernel in the init phase. The script will run in background and collect process information, CPU statistics and disk usage statistics from the /proc file system. The performance data are stored in memory and are written to disk once the boot process completes.

To install Bootchart fire up your terminal and run this command

sudo apt-get install bootchart

The bootchart result is saved as an image after every boot process of your system and the image are saved in /var/log/bootchart/

Go into that folder after rebooting your PC to see how was your system's booting performance. How many seconds it took to boot?

Mine take around 30 seconds to boot.

This app will help you to keep an eye on your Ubuntu's performances every now and then.

Enjoy!

Sometimes we need to open a Terminal in a hurry at a particular location and the easier way to do is to add a "Open in Terminal" option in the right-click menu.

For doing that we have to run this command in the terminal.

sudo apt-get install nautilus-open-terminal

Now whenever we right-click on or in the folder or on the desktop we will get the option "Open in Terminal" in the menu and we can open the terminal.

Restart Gnome for the changes to take effect.

If you want to run Nautilus as root {Although I will not recommend it because you can by mistake can do irreversible damage to your OS} but sometimes I need to use Nautilus in root mode to do some of my works.

Well normally I would just go to the terminal and I will type sudo nautilus or gksu nautilus in order to start Nautilus in root mode but I can also do this in GUI mode.

In order to add a link to Nautilus {with root permission} all you have to do is go to System -> Preferences -> Main Menu

Select System Tools from the list of Menus

Click on the New Item Button from the right hand side of the window

The Create Launcher window will open.
Fill in the boxes as it is shown in the image and close the Window.

Now close the Menu Editor as well.

And you're done.

Now whenever you want to start Nautilus in root mode just go to Applications -> System Tools and click on Root Nautilus

Enter the password and Nautilus with root permission will open.

Have Fun!

The first thing new users realised after installing Ubuntu is that they cannot play most of the songs and videos and this is because Ubuntu by default do not include this pakages (codecs etc) due to legal reasons (copyright, license, patent, etc).

Here is where we need Medibuntu

Medibuntu is a packaging project dedicated to distributing software that cannot be included in Ubuntu for various reasons, related to geographical variations in legislation regarding intellectual property, security and other issues:

• patentability of software, algorithms, formats and other abstract creation
• legal restrictions on freedom of speech or communication
• restrictions on the use of certain types of technical solution, such as cryptography
• legal restrictions on imports of software technology, requiring for example specific permissions
• etc.
  

Medibuntu has free and non-free components.

Disclaimer: Patent and copyright laws operate differently depending on which country you are in. Please obtain legal advice if you are unsure whether a particular patent or restriction applies to a media format you wish to use in your country.

See Ubuntu's Free Software Philosophy and the FreeFormats page for a more comprehensive discussion of these issues.

Adding the Repositories

Add Medibuntu to your sources.list, as well as its GPG key to your keyring. Make sure to use the correct sources.list that corresponds to your current distribution.

Go to the Terminal and type the below commands based on your version of Ubuntu OS.

Ubuntu 6.06 "Dapper Drake":

sudo wget http://www.medibuntu.org/sources.list.d/dapper.list -O /etc/apt/sources.list.d/medibuntu.list

Ubuntu 6.10 "Edgy Eft":

sudo wget http://www.medibuntu.org/sources.list.d/edgy.list -O /etc/apt/sources.list.d/medibuntu.list

Ubuntu 7.04 "Feisty Fawn":

sudo wget http://www.medibuntu.org/sources.list.d/feisty.list -O /etc/apt/sources.list.d/medibuntu.list

Ubuntu 7.10 "Gutsy Gibbon":

sudo wget http://www.medibuntu.org/sources.list.d/gutsy.list -O /etc/apt/sources.list.d/medibuntu.list

Ubuntu 8.04 "Hardy Heron":

sudo wget http://www.medibuntu.org/sources.list.d/hardy.list -O /etc/apt/sources.list.d/medibuntu.list

Then, add the GPG Key:

sudo apt-get update && sudo apt-get install medibuntu-keyring && sudo apt-get update

And you are done.

If you are confused on what is repositories then you should gain more
knowledge on this by Clicking Here.

Now you can install pakages like

libdvdcss2
w32codecs
w64codecs
ppc-codecs

And many more pakages from Synaptic Pakage Manager.

Have Fun!
