Installing a software:

Ubuntu does not support direct executable files. You will either be provided with a compiled object that can be installed as such or the complete source code itself. In case of source code, it must be compiled first to proceed with the installation. There is no fixed way to compile the code. It depends upon the language in which the software has been written.



Fully compiled software will have standard extensions which Ubuntu understands by their extension.Some standard file type are

  • .run - These files types must be executed with shell command as
  • sh .run
  • .deb - Deb is the abbreviated form of Debian packages. These packages can be installed right away by double clicking.It opens itself in package installer.
  • .bin - These are standard binary files. They might be locked sometimes. They must be provided privileges before executing. The privileges can be changed by the command chmod with the switch +x.To install the software, use the command ./[FILENAME].bin (note the dot in the beginning)

There are many other ways of installing a software.

Synaptic Manager:

This is a built-in Ubuntu installer. Ubuntu , keeps track of many useful and popular packages. They are indexed in the synaptic manager. You can install the software using the synaptic manager, if the software is listed in it.

To start synaptic manager, use the command sudo synaptic



Application Package Tool :

APT is one of the typical features of Ubuntu. There are plenty of software and utilities that can directly be installed in your system without having a downloaded soft copy. Just naming the package would suffice. Some famous package that can be installed with APT are



sudo apt-get install sun-java6-sdk
sudo apt-get install xmms
sudo apt-get install vlc
sudo apt-get install mvn
sudo apt-get install ant
sudo apt-get install svn

Almost all applications can be opened using a command line. Command line version of software are faster than graphic interface as they occupy less memory.This could be a handy guide for beginners. But this is just a piece of Ubuntu. There are many things are there to be learnt to play with Ubuntu.

2012 End of the world?

This is a hottest question around the world and am no exception for that.Still there is no clear evidence about what is going to happen.Theoretically , the Mayan calendar ends.After that a new Era emerges, which will be similar to restarting the world. Assuming this as just an assumption. The Assumption is based on the fact that scientists believe that, the planets and other bodies in space, might undergo physical changes (Spiritual in case of Astrologers) which might cause a natural calamity. The Universal fact says " EARTH WILL BE ALIVE AS LONG AS THE SUN IS ". So it is clear that, world will not end, but we will face an end. The actual meaning of the phrase " WORLD ENDS " is , the huge mass called EARTH should explode and scatter into the space as small pieces losing its gravitational force. So there wont be any chance for living creatures to exist once again. But research and prediction say, EARTH will be restored after a huge disaster. Living creatures will n...

HTC Wildfire - Display ,Touch Sensor and Accelerometer

Touch Sensor The first thing i want to tell is there is no irritating double tap , that we see in mobiles like Nokia 5800 .The touch sensor is awesome and some times over sensitive. Whenever i take a snap of something and hand over the device to some one, they touch some part of screen while receiving it and finally they complaint that they see a diff...
