Sorry about the first link. It seems he posted it limited, which, by Google+ standards leaves it hard to share. At least the direct youtube link works.
Folks like Kamil use Ubuntu like I used Mepis or Mandrake back when we were learning. They're very passionate about Ubuntu because it freed them from Microsoft.
I've read some of Kamil's Ubuntu how-to's in the past, and he certainly knows his way around Ubuntu, he's just a Linux newbie, as are many of us in different degrees. Eventually, he'll need to find a way to experiment more, something that is hard to do with Ubuntu.
