ZDNet's Dana Blankenhorn reports today on a new open source navigation project launched by European GPS company TomTom that adds additional functionality to navigational devices, regardless of the make or model. The OpenLR project aims to put navigation data on top of a unit's existing database so drivers can access local traffic, weather, and other useful information as they travel.

As some OStatic readers have likely already heard, Microsoft is taking TomTom, a manufacturer of in-car navigation devices, to court for patent infringement. This is especially disturbing to those in the open source world for at least two reasons -- Microsoft's previous claims that Linux violates over two hundred patents it currently holds, and three of the claims against TomTom deal with TomTom's implementation of the Linux kernel in its products.

Techdirt's Mike Masnick presents some good analysis of the story, including links to the patents in question and those with particularly tenuous claims (in terms of infringement and patentability, in a few instances). While this is worrisome to those who use Linux, and certainly causing TomTom executives to lose sleep, I can't help but wonder, really, what this positioning actually means. Why is this coming up now? If hundreds of Microsoft patents are being violated, why go after a company infringing on eight (with three relating directly to Linux)? And why TomTom?

Mozilla Labs recently offered a sneak peak and download of Geode. Geode is one of the first applications to use the new W3C geolocation specification API. It is currently available as a plug-in for Firefox 3 (and seems to only support Windows and Mac systems at this time). Mozilla Labs indicates it will likely be a new feature integrated in an upcoming browser release.

Geode uses web-based tracking, which tends to be faster than the traditional GPS geolocation methods. This would enable Firefox to sense the user's location and give information, for example, on local businesses, or quick access to local news.
