Sometimes I use “Record my desktop” in ubuntu to make a screencast which I send to windows users. The output of the screencast is a .ogg file which I need to convert to a .avi

Here is the command to make the conversion:

mencoder out.ogg -o out.avi -oac mp3lame -ovc lavc

Installed the new ubuntu 7.10 two days ago

daneskildsen — Mon, 22 Oct 2007 17:30:56 +0000

The new version of ubuntu – version 7.10 is now available and upgrading from 7.4 was very very easy. When you start up ubuntu 7.4 a little window pops up and informs you that a new version is available. Everything happens automatically. It took a few hours to complete. The first two times I tried to upgrade it failed because there were so many people downloading from their servers.

There is a lot more “eye candy” in the new version.

Here is a video clip of me using my new desktop. Please note that this is a ogg file.
