Stability: Linux vs. Windows
I just like to add some example of differences in stability and security between Linux and Windows.
November 1999 I build a small network of 5 computers at a school to be used by everyone to surf the Internet, write letters and so on.
OS was Linux, some standard distribution.
I could not administer for about 10 month cause I had no time.
A friend of mine did the same with Windows NT as OS.
He had to rebuild every computer for about 7 times during that periode. His network had been cracked several times. He had to spend a lot of money and time.
When I saw the my network for the first time since 1999 last week, it still was stable, no crack reached root-level, everything worked fine. Although this net had more than 7 times as much usertime than my friend's net.
So my expirience is a realworld-thing. I will never ever even think about using Windows. And my friend decided to dump his Windows and to use Linux when he heard my story.
Thats all I as small sysadm can say about Bill's words.
