The actual url is:
http://www.arsgeek.com/?p=564

and the following is a slightly modified version (for us Kubuntu users) of the post:

  Kubuntu Tricks - how to generate a list of installed packages and use it to 
reinstall packages
(modified from http://www.arsgeek.com/?p=564)

First, let's make the list. You'll be doing all of this in a Terminal Session:

     dpkg --get-selections | grep -v deinstall > Kubuntu-files


Now you've got a list of all of your installed debs in a fairly small file. In my 
case, I simply moved this file to a thumb-drive. You could also store it on a 
seperate partition or on a disk somewhere. Heck, it's not that big, email it to 
your gmail account.

So now you've got this list and all is well, until your Kubuntu install either 
dies or has to be reinstalled for some reason. Go ahead and do the base install.

Once you've got Kubuntu back up and running, copy your Kubuntu-files back into 
your home directory and do the following:

     sudo apt-get update

     sudo apt-get dist-upgrade

     dpkg --set-selections < Kubuntu-files

Now you've told your system what it needs to install, so let's install it all.

     sudo dselect

This will open up a dselect session. Type 'I' and allow dselect to install of the 
the packages listed in your Kubuntu-files document. When it's finished, type 'Q' 
and hit the ENTER key to exit dselect.

Now you're a lot closer to where you were before.

geek out.
