Pipe Dream: Re-wiring the Net
The online world is awash with XML feeds. The great thing about XML is that you can grab it and do stuff with it very easily, because it's basically a structured text file. For example, you can feed one XML stream into another, combine them, and keep on piping them around. A bit like Unix pipes.
Hey, now that's an idea:Pipes is a hosted service that lets you remix feeds and create new data mashups in a visual programming environment. The name of the service pays tribute to Unix pipes, which let programmers do astonishingly clever things by making it easy to chain simple utilities together on the command line.
What's particularly cool about this new service is the graphical approach, which looks a lot like programming flowcharts. The currently-available pipes are rather limited at the moment - this is still very new - but it's not hard to imagine some very rich stuff coming out of this. Bravo Yahoo. (Via GigaOM.)
