I have been arguing for years that the Windows monopoly is a monoculture. It will suffer the same fate as the Dutch tulip market crash, the Irish potato(e) famine, the boll weevil infestation and other monocultures over history.
If 95% of our computers are controlled by one family of operating systems, some day there will be a worldwide infection that has the potential to wipe them out.
The only answer is Diversity. I know this is a bad word with so-called Conservatives, but heterogeneity in computers is a necessary thing in a modern, wired, connected world economy.
Think about it: if all your connected computers run Windows, there is a 100% chance that a Windows infection on one of them will spread to another.
But say you have four Operating Systems in your institution; 1/4 Windows, 1/4Mac, 1/4 Linux, 1/4 some other obscure OS. If one system gets infected, the chances of the next is 1/4. The chances of ALL your systems getting the infection is (1/4)**N where N is the number of systems in your entire institution.
But as with all visionary concepts, this will be ignored until the disaster strikes. Then everyone will ask: “Why didn’t we take precautions?”
I hear ya. I'm switchin' back to Windows 3.1.
Worse, Microsoft believes that obscurity is security.
Look at that article again:
The Stuxnet computer worm spreads through previously unknown holes in Microsoft's Windows operating system
Somehow this reminds me of the 0bama administration, everything happens "unexpectedly"...
It's our strength.
For your most obscure 4th OS,you might try Amiga OS !
