My experience with Ubuntu blogged

If you want to use ColorZilla on Ubuntu Feisty it may not work out of the box. So here is a little tutorial to get it running. (I am using Firefox 2.0.0.6 on Ubuntu Feisty) -> Should be upgraded to 2.0.0.7 now

• Download libxpcom* for Firefox ColorZilla (VS von 2.0.0.7). Alternatively you can download the newest Release of firefox from www.mozilla.com and extract firefox/libxpcom*. You only need this 3 files.
• Copy the 3 files as root to /usr/lib/firefox/

  cd /path/to/ff-libxpcom
sudo cp libxpcom* /usr/lib/firefox

  Note: I had firefox running and as I started copying firefox crashed. (So If you do not close it before it will do it for you )

• Install ColorZilla from https://addons.mozilla.org/de/firefox/addon/271

Now the Eyedropper-Tool should work. I waited a long time for such a tool =)

EDIT: Seems that other extensions are too affected such as greasemonkey or firebug. An alternative would be to install firefox the normal way and do not use the ubuntu-firefox version but I heard there are some problems with sound and flash… You can download the current one here: libxpcom* for Firefox ColorZilla (VS von 2.0.0.11), VS 2.0.0.13.

If I screencast something, than most of the time I do it with recordMyDesktop which produces .ogg-Videos. If you need to convert it so you can show it to your friend or upload it to a video hosting page like youtube or so you have to convert it into another format. I chose avi as format.

Simply fire up this command to convert your file:

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

• out.ogg is the .ogg-file you want to convert
• out.avi is the .avi-file you want to create
• mp3lame is the used audio-codec (here mp3)
• lavc is the used video-codec (here libavcodec)

For more information you can look at the MPlayer manual page.
