Android is Open

We all know what Open means in Android: Android is an “open” operating system in name only. Sure, you can get the source code and mess around with it, but there are no mainstream generic Android phones that work on any carrier, and no carrier-sold phones are simple to crack open and do what you

Eye-Fi for Security

This is fun. Really. Alison DeLauzon, Reuters reports, had her camera stolen when left an equipment bag in a restaurant in Florida. The folks who allegedly took the bag also took pictures of themselves, which isn’t unusual. But DeLauzon had an Eye-Fi wireless Secure Digital (SD) card in her camera, received as a gift. The

FON on NYTimes

Great article about FON on New York Times. It also has some good insides about the company, business model and inevitably Martin Varsavsky (Mr Jazztel, Ya.com) profile & lifestyle.

Meraki and a few impressions

I’ve been working on a Wifi Mesh experiment with Meraki Gear for the last 2 months. I was looking for a better low-cost single radio mesh alternative to the OLSR/OpenWRT platform (Freifunk Firmware). So far, the experiment is going well, it has some glitches with coverage due to the low-power radios of the Meraki Mini

Mesh on the OLPC

If you’re into Wifi Mesh Protocols there’s interesting news on the OLPC front and MIT work. They’re developing a new protocol based on a “probalistic presence mechanism” right into the OLPC firmware. Polychronis Ypodimatopoulos, Pol for short, has developed a “probabilistic presence mechanism” in the mesh firmware for the OLPC. The presence mechanism uses a
