Not sure why. I had assumed that the short code was a hash of the lat/long and not a database lookup.</blockquote> Different platforms (with different capabilities), running different browsers give you different degrees of accuracy in the detected location. It can be as coarse as a reverse IP lookup (if everything else fails), or as accurate as a GPS point. In the latter case, two consecutive lookups at Geo.gy would give you two slightly different locations even if you have not moved at all. While I'm checking whether the exact same lat,lng pair has been posted before so that I give you back the same hash key, the slight change in your position will generate a new key. I will change this to group together pointers that are closeby under the same hash key. I just have not decided on the resolution yet. <blockquote>* To be generally useful, it would be nice if you added Google geocoding of arbitrary locations instead of only “here I am” locations.</blockquote> Google already does that and I preferred to stick to things that are not available at the moment ;) cheers Pol Hey, thanks for the comments.

With the advent of technologies like tornado and websockets though, the original code is rather an embarassment :) The project was inactive for a while but we're now almost ready to put it back into public - with several modifications from our previous approach. The most important ones are: - No user interface! I've come to realize that it's more important to have a web-based agent that provides JSON output and a clear API, rather than contriving an HTML-based interface that uses templates. You can still use "stand-alone" HTML apps that leverage our restful interface. - Usage of key/value pairs - we've abandoned the relational database approach for the simplicity and portability of a flat, key/value pair structure and, guess what, we don't miss it at all! - All API are centered around the user, not the application - By following a /USERNAME/APP approach for all calls we have significantly simplified the process of creating and reusing applications and it becomes easier to migrate user agents between different hosts. - We moved from django to tornado so downloading and running the code requires no installation (tornado's tiny code footprint is included in the source code). more to follow soon, including the source code. p.
