Imagine, if Microsoft did the same: introduce a mandatory app store for windows and charge 30% for all music purchases in iTunes.
I hope Amazon will develop a web based ebook reader and screw Apple.
Crazy people claim that NASA forged all those moon landing videos and photos (missing stars etc.) They have to refine their theory now it seems (maybe NASA forged these pictures as well)...
Use Unison! It is a wonderful program working both on unix and windows. If a file is modified only on the server or the laptop, then the program automatically will propagate the modified one (based on check sum and not on date) to the other side. If the file is modified on both sides, then the use has/can decide what to do on a file by file basis. It inteligently updates files (moves only the changed parts of a big one). I have been using unison for 7 years and I had no problem with it and can only recommend it. I also liek to synchronize it manually (I know I always have a backup if I mess up something), but you can run it automatically (every 10 minutes or so).
Hi! I am working with these Berkeley motes in the last two years. They are getting better, but still rather resource constrained. There are two research prototypes: MICA and MICA2, both basically have:
ATMega128 7.3 MHz microcontroller
4 KB RAM, 128 KB PROGRAM EEPROM,
512 KB flash memory for measurements
433 MHz wireless radio, CC1000 transciver,
30 messages per second, 29 bytes in each message
radio range is about 100-300 feet
runs on two AA batteries for 3 days continuously
various pluggable sensor boards
The motes run the TinyOS, freely available from sourceforge
The Berkeley guys are working on the dust mote,
1 mm2 target size including the radio chip. The biggest limitation now is the battery power and the radio range. Even if they can get the size down to "dust", the antenna HAS TO BE 1/4 of the radio wave length. For the 433 MHz version this is around 8-10 inches! So these dust motes will have "tails". Eventually, these could painted on the wall, or dumped from the air for millitary applications. Lot's of unsolved problems. For sensor networks, how do you obtain large amount of data through a few base stations? Smart aggregation and routing protocols need to be employed, and the network must process the data by itself.
