Quantum GISWith all the rave reviews that Ubuntu 10.04 Lucid Lynx has been getting over the past couple of months, I couldn’t help myself upgrading and checking out the exciting new features and the enhanced interface, which I think was a much needed overhaul for the best desktop Linux OS.

A new version meant fresh installation of all the open source GIS goodies starting with QGIS. The latest version 1.4.0-Enceladus for Lucid is already available in the Launchpad UbuntuGIS repository and with a new command (add-apt-repository) for updating /etc/apt/sources.list with locations of repositories, the installation is simple and straightforward.

Bring up the terminal and issue the following commands.

Add the repository using:

sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable

Make apt aware of the new repository:

sudo apt-get update

Install QGIS

sudo apt-get install qgis

Once the installation is done, open QGIS from Applications -> Science -> Quantum GIS

Get a clean desktop on Ubuntu

 Linux, Tips  1 Response »

Be it GNOME or KDE, most Linux power users prefer to have their desktops slick and geeky with screenlets, gadgets, docks or conky. But I on the other hand (cannot call myself a power user) like to keep my Ubuntu desktop clean without any visual clutter by preventing nautilus from drawing  icons. It is only then I believe the true beauty of a wallpaper can be relished.

To treat yourself with a clean desktop, bring up the run application dialog with Alt + F2.

Type gconf-editor to invoke the GNOME configuration editor. Navigate to the key /apps/nautilus/preferences and scroll down to the key show_desktop.  Uncheck the box next to the key under the value column.

show desktop

P.S. : Right-clicking on the desktop is disabled with this setting

For the Linux newbie from a noob

Scenario: You have quite a large number of zip files in a folder with other files and would like to avoid manual labor of extracting one file at a time.

The below graphic is the result of extracting an e-book downloaded from the web in compressed format.


Solution: A simple shell script to extract all files at one go.

Save the script with a .sh extension and make sure it resides in the same directory as the compressed files.

Fire up the terminal, cd to the target directory and execute the script using ./xxxx.sh

P.S.: Has been successfully tested on Ubuntu

Open .rar files using Archive Manager in Ubuntu

 Linux, Tips  1 Response »

The “Archive Manager” that is built into Ubuntu (Ubuntu is the only Linux distro that I have tried so far) to handle archive formats has no native support for the .rar format.

Try opening a .rar file with the Archive Manager and you are presented with an error.

Fixing this problem requires installation of an unarchiver for .rar files. This is readily available in the repositories in two packages – unrar and unrar-free. The unrar package is from RARLAB and the unrar-free is from Gna! which is the free software version of the non-free unrar utility.

Fire up the terminal and issue the command
sudo apt-get install unrar-free

Once the package is installed, Archive Manager should now be able to extract files with the .rar extension.
