Wireless devices espically ones that operate in 2.4ghz range do not work underwater. So if you drown and sink to the bottom of the pool no signal will get out. Thats why all underwater communication is either extremely low freq, tethered, or accoustic.
You could make it into a maxi pad. It seems like the gps and circuitry are miniscule. The battery seems like a issue but there are lithium polymers that are thin, flexible and powerful. The issue does come down to antenna size. I've never seen a gps antenna small enought to be unobstrusive and plus the line of sight thing might be a problem since you won't get a signal indoors. However for the transiever, those are at 2.4 ghz which should be easily concealed. So think very tiny cell phone which is possible with today's tech. In fact they should just throw out gps, and use gprs and let the antenna towers give you an approximate lcoation.
=D
Wait, you mean to tell me the the movie was suppose to be somewhat serious. Cause i totally thought it was an intentional satire kinda like the movie Team American done by the creators of south park.....
The fact that each node in the network is low bandwidth and low processing power makes it very challenging to implement security. There has been encription schemes developed but its challening to build strong encryption without incuring unacceptable overhead. And even with strong encryption the network is susecptable DOS attacks since you could just flood the network with junk msgs.
Well in the future, we will have sensor networks everywhere. And where ever your walking human sensors spewing wireless data goes their data will be picked up by the ever present and ever watchful sensor nets and it will be relayed back to their doctors =D
" Above all he believes that open source software will cure the piracy problem. (more) "
Well duh, if all programs are free then of course no body would be able to pirate something that is in itself free. I'm sure there'll be no problems convincing all the programmers out there to work for free.
Open Source Network stack built on zigbee radios already exits. Check out the tinyOs effort. Compare to Blue tooth, zig bee radios are much more power efficient.
Its is usually implemeted as a circular linked list data structure where each node has three pointers which point to the previous, next and the data entry.
Well considering he's running a console system on some AA batteris it won't be too long before the thing croaks. And ppl thought the battery life on the new psp is bad.
quality of education depends on more than the teachers, it also depends on the school. You can go to an average state school, but the ppl there overall won't be as hard working and intelegent as say stanford or berkeley. As such if your smart you won't be pushed by your peers and never realize your full potential or lack there of =\
I don't think they appreciate someone sugguesting using animals they consider as incarntions of gods to generate electricty. Its like asking the pope to run on a treadmill so you could have your email.......
I've connected something running off an ac outlet that wasn't isolated to a programming board. It blew a pretty big hole in the cpu. And it stopped working....
If your interested in wireless sensor networks, we're working on that stuff at UC Berkeley. Heres a link to the home page.

Go to the publications link if you want details.
yup, we're doing that at cal right now. we're harvesting from ambient vibrations and magnetic fields. Although the amount of energy you can get isn't really enough to power the processor and radio packages. Untill they can signifcantly reduce the amount of power consumed by radios we'll still have to depend on batteries
If you have to take calc twice in HS then chances are your not meant to be a math person. For the most part hs math is much easier and you get much more attnetion devoted to you. Most prominent colleges could care less if you failed ur calc course especially at places like Cal, they figure there'd be plenty more where you came from
Ah i see i'm not the only Double major here. I'll be done in a year. But to be honest, it really hard to see direct influence with math and cs sometimes. Especially when it comes to classes like Real Analysis, or even abstract algebra. I mean sure i can do modular math better and i have a slighly better understand of hashtables, but really what can u do with that in real life. To be honest unless you wanna be a researcher or work for a research institution, most cs jobs don't give sheat about your math skills. Sometimes i wonder if i should have just ditched my math classes and learned some more usefull applicable things.
oh yeah classes
numberical analyiss, abstract algegra, linera algebra, calculus courses, stats, complex analysis, algorithms...
Thats not true, i'm a cs and math double at CAL. Thinking back math has helped me alot with critical reasoning, you'd be surpised after doing obscure profs on theorum you'll never use in real life can make you good at picking out bs from other programmers.

Ahem, i think you missed the irony of the comment. Are you by any chancd autistic?

In Korea only old people use .Net natively on their cpu's.

would you like to be the one who does that?

i dunno i think i see some rolls rolls there.
I'll find out soon enough. I just got bought one off their site a few weeks ago.
