Tired of waiting for Google to release a proper Latitude API, I went ahead and scribbled latitude2brightkite.sh – a script that checks-in your Google Latitude position to Brightkite using the Brightkite REST API and the Google Public Location Badge.
This script is an ugly mongrel hack, but that is what you get when an aged script kiddie writes something in a hurry. The right way to do it would be to parse Latitude’s JSON output cleanly using the Perl library. But that dirty prototype took me all of ten minutes to set up while unwinding between meetings, and it now works fine in my crontab.
The main limitation of this script is that your Google Public Location Badge has to be enabled and it has to show the best available location. This means that for this script to work, your location has to be public. The privacy conscious among my readers will surely love it !
This script proves that automatic Google Latitude position check-in in Brightkite can be done, it works for me, and the official Google Latitude API will hopefully soon make it obsolete !
Meanwhile, grab the code for latitude2brightkite.sh, put it in your crontab and have more fun with Brightkite and Google Latitude… To me, this is what both services were missing to become truly usable.
Of course, doing it with “XEP-0080 – User Location” via publish-subscribe (“XEP-0080 – PubSub” would make much more sense than polling an HTTP server all the time, but we are not there yet. Meanwhile this script could be made more intelligent by only checking in with Brightkite if the Google Latitude position has changed. I’ll think about it for the next version…
