My new spare-time project blogloc is not even out of closed beta yet, and already people are finding alternative ways to use it! Lacking a decent mobile phone with a GPS (c’mon, it doesn’t even have 3G, jeez) Katz has elected to use blogloc as her personal “I would rather be here” sidebar widget, and […]

All right. As I said in one of my last posts, I really want one of those maps on my blog’s sidebar where I can share my current geographical location, directly from my GPS-enabled mobile phone. I also said that there are several tracking services out there that give you a mobile client and an […]

Over the weekend I took some time to thoroughly test drive the Nokia N95‘s Internet-based A-GPS.

Absolutely awesome: A zoomable, draggable Web map of Hong Kong in Sim-City-like 3D pixel art style! The level of detail and accuracy is amazing: The hotel I stayed at the last time, the Polytechnical University where LBS 2007 took place – all there, correctly shaped and textured! (I’m still looking for that Vodka bar in […]
