In technical aspect, basically, a website should be compliant with most of the web browsers, which are currently being used.

Ubuntu Jaunty Jackalope

Ubuntu Jaunty Jackalope is still in the Alpha 5 stage. But couldn't prevent installing that because of the curiosity I had towards it. :)
So finally upgraded the system from Hardy Heron to Jaunty Jackalope. Following commands were used.
1. Alt+F2 -> gives the 'Run Application' dialog.
2. There entered 'update-manager -d'
3. After the processing it showed that a new system is there to make an upgrade.

Everything went okay except compiz as I can see for the moment. But it is a minor problem. Display problem with lower graphics went okay after removing the following lines from xorg.conf and rebooting the system,
1. Driver "fglrx"
2. Option "VideoOverlay" "on"
2. Option "OpenGLOverlay" "off"

System seems to be having smaller icons than the previous systems. But I am not 100% sure about that, but I feel like that. Have to try a little bit more to find out what's new. It's still alpha. :)

How to remove the audio track from an AVI file (using mencorder)

mencoder -ovc copy -audiofile soundtrack.mp3 -oac copy video_nosound.avi -o video_new.avi

How to Rotate a Video Taken by a Camera Using Mencoder

It was really essential to rotate a video before you post on to your blog or somewhere else if the video is taken in the other orientation from your camera. If you have mencoder, you can fire this command on the command line (I am considering Linux) from the place that you have your video file that you want to rotate.

mencoder -vf rotate=1 -ovc lavc -oac copy name_of_your_video_file.avi -o new_name_of_the_converted_file.avi

Change the names of the video file as described. Write the command continuously on the command line with relevant spaces.

If you don't have MPlayer or Mencoder you can download it from here.

Nautilus Scripts

Nautilus scripts are scripts embedded to nautilus file manager which is the official file manager in GNOME. These scripts can be run from the menu you get by right clicking somewhere, probably on a file so that you can fire an instant command on that file.

There were lacking some scripts for linux earlier but now it is not true anymore. These two scripts will be very useful to anyone who works with images and videos frequently.

1. nautilus-image-converter
You can just run this command on the command line
sudo apt-get install nautilus-image-converter
2. nautilus video converter

Click on the link and follow the instructions given by the author carefully.

Enjoy the scripts.
