This section is dedicated to the Unix-like OS!
In fact I think only to Linux, a OS stated back in 19xx by a student , Linus Torvalds, just for fun!
By then many people had began to work with this enviroment and nowadays it is very very popular!
The main advnatage of it is that it is FREE! Almost all apps for this OS are free of charge!

I started using this OS back in 1998.Then I've bought a RedHat distribution and from that time on I stucked with it! I can't say Linux is a user friendly OS nor easy to use!
I had major problems to set up my box and also running it! I can't say I am a guru right now!In fact I know nothing more than the essentials!
You see with Linux you must have the time to learn and practise, which I do not have right now! But be sure that I will find it!
