Almost-Satnav For Cycling
An anonymous reader writes "A couple of guys (us) in Cambridge have written a cycle routing system, CycleStreets.net, based on open data, and have now released it as a free iPhone app. It's been done on a shoestring, in spare time. There's an API and some disruptive tech in the form of a photo submission screen where street problems can be submitted directly. Because it's open data, you don't have to wait 6 months for the routing to be fixed if there's a bug. Android and .mobi versions are in the works, with the apps being done on GitHub."
Congrats on Slashvertising your app. In Holland we've had www.openfietskaart.nl for a while already. There's also www.opencyclemap.org. Yes, open mapping is cool, no, this is not news.
With a suitable Garmin GPS (there are a number of models that do auto-routing that have bicycle mounts), you can load up an OSM based cycle map and get cycle routing that way. See http://wiki.openstreetmap.org/wiki/OSM_Map_On_Garmin/Cycle_map
If you already own one of these, you'll probably find it is somewhat more water resistant than an iPhone.
I think much of it has to do with lessening chaffing, wearing a material that will let your sweat evaporate vs just absorb it, not as a fashion statement to try to catch the eyes of condescending people like you and your wife. Those who ride longer distances/more strenuous routes seem to think it is worth wearing even when having to put up with ribbing/heckling from people like you, so apparently the benefits are noticeable enough to make it worth their while to pay the extra expense of cycling gear (a T-shirt and shorts are quite a bit less expensive) along with wearing it out on a ride on public roads/paths.
