Mail out geohash/lat-lon stickers (and/or QR codes) to EVERY address, ask people to stick them on their mailboxes – this could broaden GPS usage
In this third tutorial, we scrape the incoming text messages for pairings of strings in the format “key:value value …”, which we parse out with a regular expression and store in a separate Keyvalue table. This allows us to intelligently search and manipulate the data, as well as to geocode addresses submitted along with data. This yields latitude & longitude data for a given text message.

This builds on the code written in the last tutorial, Batch importing text messages from Twitter in Rails
A preview of the code I’m developing – I’m calling it Cartagen. It’s a web-based vector framework for dynamic cartography. A Ruby server receives map data from OpenStreetMap and from participants’ cell phones in real-time. Data is plotted in native HTML 5 with the canvas element, and styled with a new stylesheet format, GSS: Geographic Stylesheets. I’ll be demoing a more complete system during the MIT Media Lab’s Sponsor Week.
Books that have made the shortlist but inexplicably failed to win include “A Pictorial Book of Tongue Coatings,” “Sex After Death,” “Waterproofing Your Child” and “Cheese Problems Solved” — which, its publisher says, provides “responses to more than 200 of the most commonly asked questions about cheese,” with special emphasis on mozzarella, blue cheese and cheddar.
