Where I went yesterday, via my Android phone

You know what? I’m glad this whole phones keeping track of everywhere you go thing happened, because, pushing all those pesky, minor concerns about privacy away, it’s really kind of cool!

Hot on the heels of the iPhone tool that showed us the smorgasbord of data that’s being stored, someone decided to see what Google / Android does. It turns out they store location information as well, just, no way near as much as Apple

After a period of time, 12 hours for cellular data and 48 hours for WiFi data, has passed, the location data is renewed by a new request from Google. It is also limited to a maximum number of entries so that the database doesn’t grow too large. 

Swindon says that the location file pulled from his phone contained roughly 13,000 entries related to cellular network tracking. By contrast the Android file is limited to only 50 entries in the cellular location database.

Maybe it is just a bug, or lazy programming or whatever on Apple’s part, but it makes sense, especially in Google’s case, where they delete / refresh the data, and you can see it being useful for location-based services.

SXSW – The context layer

There was plenty talked about at SXSW Interactive, and for the most part, it was reaffirming my existing knowledge more than anything else. One thing that did stand out, and that I’ve found myself talking about since I’ve returned, is this whole concept of a Context Layer to sit on top of all the content that exists on the web, and specifically in relation to Location.

This is isn’t something new or revolutionary, but it makes sense in feeling like the logical next step.

We’ve already seen Web 2.0 push personalisation, and the Social Web push relevance via social graphs [no doubt this will continue *cough* +1 *cough*], but utilising location, especially through mobiles, is still in its infancy.
