Weather.com Moves to Open Source.

<blockquote> Four years ago, Weather.com, the online counterpart of The Weather Channel Interactive Inc.'s 24-hour TV channel, relied entirely on proprietary commercial software to serve up millions of Web pages of maps, forecasts and hour-by-hour weather data every day.

Today, the Atlanta-based Web site serves more than 50 million pages on stormy days, but it runs almost entirely on open-source software and commodity hardware. And since the move to the new architecture, it has slashed IT costs by one-third and increased Web site processing capacity by 30%. </blockquote>
