From time to time I really want make it hard for me to seek for distractions.

I found myself using the nice Mac OS X tool Freedom all the time. Freedom disables the network connectivity, which means no Twitter, Facebook etc.

But when I revisited the site I found that the author now charges 10$ for it - Thats just a little bit to expensive in my opinion.

So I went out and it took me 5 minutes to come up with

echo "Enough of this filthy internet" | cowsay -s
sudo route -n delete default &> /dev/null

Cowsay required. (If you don't want to install cowsay just remove the line!)

< Enough of this filthy internet >
            (__)       )/
             U  ||----w |
                ||     ||

To reenable your internet you have to add back the default route or restart your computer.
