[OSM-talk] Nearby Users

[Mikel Maron]

Thanks Frederik for kicking this off, good discussion of a *potentially* v useful feature.

No matter how nearby users presentation is tweaked and filtered, I reckon we need consider how to architect this efficiently. To calculate "activity", by changesets or sign up date or any other parameters, using rails models or directly in SQL will be even slower than currently. I'm not familiar with exactly how Pascal does his calculations, but I'm guessing it's based on planet diffs and API queries when needed, with results stored. I'd love to see Pascal's system integrated into OSM.org, on both the friends and nearby users views (our "news feed"), and on user profile pages.

What's the best way to set up this kind of async stats processing, and integrate into the rails app?
