Offline Gnome Dictionary on Linux mint and Ubuntu:

The dictionary tool that comes with the gnome requires Internet connection to retrieve information from the dictionary server.So without an Internet connection it is useless.We can install a dictionary server on over local machine to avoid this constraint.
Installing Dictionary on localhost:
Copy and paste the following command to install dictionary server package.
#sudo apt-get install dictd
After installation of the above package you will need to install the database and English dictionary so enter this command.
#sudo apt-get install dict-moby-thesaurus dict-gcide
After the installation of above packages you can now use command line to consult dictionary as:
#dict -options ur_word

Customized Desktop for Ubuntu 10.X using AWN and Conky:

AWN (avant window navigator) is a feature rich dock application for linux based distros. It includes almost every applet that comes with default ubuntu gnome-panel and pretty more customizable with its included themes and available third party applets.
So AWN can be a fancy as well as a more functional replacement to the default gnome-panel.

Installing AWN with lucido style:
what is lucido? Take a look at this screen shot :
Lucido is an AWN style which is now available as a part of AWN trunk, so instead of installing the stable release available in synaptic package manager ,we will install AWN trunk available through AWN trunk PPA.
