I recently had the opportunity to do some hacking in the Czech language. It turned out to be very worthwhile even though I couldn't achieve what I wanted.
We had some guests staying with us from the Czech Republic. One, who brought their laptop along, spoke only a little English. Hence we had some fun trying to get their laptop connected to our network and then the Internet.
First, there was the Czech keyboard. Some letters are in different locations. So when you're typing passwords you type the wrong thing without knowing it.
