Comment Another solution. (Score 1) 225

This plant sucks water from the Laguna Madre (the body of water between the Texas coast and Padre Island) then spills the water into the Oso Bay, which is in turn connected to the Corpus Christi bay. This plant is a natural-gas fired plant, but evidently had coal in mind with the docks...cooling water and fuel via the same route.

Copyright does not give the property holder the right to tell users what color/brand glasses they are allowed to wear when reading a particular title and this is really no different. Amazon/Kindle should stick to their guns and let the end user decide to turn on the TTS engine or not. Besides, most people can read a lot faster than even the fastest discernible speech.

Not when the yellow period is shortened to increase the ticket yields, which I've not yet seen myself in my location, but have heard about. I'm not one to advocate running red lights, but if going up against intentionally shortened yellow lights, I say countermeasures are appropriate and justified. If a locale wants to play dirt, this'll shield their dirt.

Comment Blind Them!!! (Score 1) 311

Here's a neat idea. I really want to do the same with my license plate for the stupid redlight cameras in my city, but was thinking a few strong camera strobes with an IR filter set up as a slave flash would work better.

This IR hat hack is cool, but needs to be modified to regulate the current through the LEDs or they'll burn out quickly.

Comment payback period question (Score 1) 371

I wonder how long a GW satellite would have to operate to capture the amount of energy required to build the PV arrays and the rest of the sattelite, the rectenna, and match the energy consumed in producing and operating the spacecraft used to put it into orbit. Its my understanding that the amount of energy used to create PV arrays is pretty substantial alone...years worth of operation on earth. I hope this is a lot better both in efficiencies creating the modern PV panels, and in capture efficiencies.

Comment ...and we're paying $0.20 USD for 100 bytes SMS! (Score 0, Offtopic) 386

Why the hell are we still paying for text messages? Yeah, I know this is offtopic, but it's just freaking sick that the rest of the civilized world is much more forward thinking than here in the US in terms of data services. Why do we tolerate being the cell oligopoly's little bitches? This is f***ing madness.

Seriously, I'd just overwrite the device with a utility such as dban then keep my mouth shut, forever. This is the advice I'd offer anyone in this sort of situation. I actually take it a step further in that I dban _every_ used storage device I get without first looking to see what is on it, so I have no clue if I ever received something via a second-hand device that I should not have.

value of the recording vs penalty...

The value of the suspected recorded content may give the owner of that content far more political leverage than some stupid law gives his oppressor. This, of course, only applies if there exists some sort of [even potential] automated dissemination of the aforementioned data. If the oppressor knows the user has the only copy of potentially incriminating evidence, it would be a very different and dangerous circumstance for the user.

Comment 1-way encryption (Score 2, Interesting) 269

This is the perfect opportunity to use some sort of crypo that encrypts the data stored (video, whatever) in a block by block fashion as it is recorded, but encrypts with traditional PKI so that there is no open session to attack. Also, the secret key shouldn't be stored on the device but instead reside with the news agency, trusted friend in another country, etc. In a nutshell, devices from video cameras to general-purpose gps-enabled geek toys shouldn't be made into easy tools for a repressive government to compile evidence against the user of the tool. I also realize though that these repressive regimes could just outlaw the crypto and make that penalty very harsh/cruel/insane, but then there's also the whole field of stenography, and this cat and mouse game can still continue ad nauseum. I really would love to build something like this out of a DV camera and some sort of small embeddible computer that could handle the I/O and crypto at DV rates.

Submission + - FCC Rules update July 20, 2007 -- 802.11a concerns

mwilliamson writes: "The FCC is will soon require protocol changes to 802.11a to automatically avoid interference to military and weather RADAR systems using the 5 GHZ spectrum. At best, this will probably require a firmware update on your access points. More information can be found at(PDF): http://www.cisco.com.nyud.net:8080/application/pdf /en/us/guest/products/ps5861/c1244/cdccont_0900aec d801c4a88.pdf

Quoting from this article: "In order to operate in the 5 GHZ bands radios must comply with two features that are part of the 802.11h specification-Dynamic Frequency Selection (DFS) and Transmitter Power Control (TPC). DFS dynamically instructs a transmitter to switch to another channel whenever a particular condition (such as the presence of a radar signal) is met. Prior to transmitting, a device's DFS mechanism monitors its available operating spectrum, listening for a radar signal. If a signal is detected, the channel associated with the radar signal will be vacated or flagged as unavailable for use by the transmitter... [SNIP]...All WLAN products that ship in Canada and the US on or after July 20, 2007 must meet the DFS for FCC requirements.""
