Usually I enjoy everything which has to do with computers, but there are some 
areas which I'm specially interested in. 

I specially enjoy to work and develope under Linux. Linux is my OS of choice 
because I like the idea of the open source concept. Moreover you can get all 
important applications for free and therefore it's rather easy to geht started 
for a programmer. Another thing I love is the great command line interface
Linux has. You can really do everything from the command line, a feature I 
strongly miss in other OS's.

Another area which I really enjoy is (you might have guessed it) the Internet.
It's just fascinating to find out how the internet works and to write 
applications which run over the Internet.
