Open source's threat to Microsoft is growing

Open source's threat to Microsoft is growing: "Computer enthusiasts at a conference here this week are learning about the latest technologies and attending sessions about a software program that dominates an important segment of the market.
But contrary to what you might be thinking, the conference is not Comdex. And the software is not Microsoft Windows.
The event, ApacheCon, is a gathering of people involved in open-source software -- computer programs produced by international communities of volunteers. The conference is being staged down the road from Comdex by the Apache Software Foundation, a group best known for an open-source program used on nearly 70 percent of the computers that store and serve up Web pages."
