I've never removed my car battery to leep it from dying. I plug my car in.
Yes, thats right, you plug the car into 110V to power a heater which keeps the oil from turning into molassis. Thats so the engine car actually start the next day.
The schedules only change twice a year... oh, and xmas holidays where they revert schedules, and, oh yeah, any other holidays they feel like screwing with it.
Use a key generator and generate new keys whenever a key is used. This way, if someone gets a copy they would have to use the key before you used yours, or their key would no longer be valid.
My girlfriend and I last night were discussing the possibility of trying to see a shuttle launch this year. We both thought it would be a cool vacation.
To see, the next day, that another disaster has struck the program is disheartening.
That this disaster will undoubtably cripple the space program for years is very sad.
TWC cable box? Is that the product/model, or just the cable company?
I can say that if you have a motorola or Generial Instruments digital box the tivo works well with it.
(Althought ig you have the AT&T branded boxes it works even better, they can use the serial port on the boxes to change the channel.) (for those motorola boxes that have the correct firmware to enable it).
But there is nothing in the specifications which makes it unbelievable.
For instance, it is quite possible to photograph a tire at that distance and analys the image of the tire. (yes, STOPPED, without bluring from the speed.).
It isn't relevent if the RFIDs can hear each other.
Basic idea (from memory) Transmit a 1 and listen for a response. If you get a response then transmit 11, listen again...
if you don't get a response, transmit 10 and listen for a response...
as you increase the number of bits you identify a specific tag (sooner or later you only have 1 possible tag left). Then, after querying that tag you turn it off. And do the sequencingain.
(Keep track of the failures from above, they can be used to speed the search).
All tis could be readily combined with in-road sensors, etc. I'm not generally a fan of paranoia of this type, but I don't see any particular reason to leave a functioning RFID in my tire.
I'd hate to get yank off the road because the previous owner of a tire had a criminal record.) (Yes, people do buy used tires.)
Forget about the problem of multiple devices. They use a protocol that works fine with lots of them.
I believe they use something similar to the protocol used by 1-wire devices from Dallas Semiconductor. (modified for RF use, but same basic concept).
Demonstrations of RFID use have previously involved shiopping carts full of product, you push the cart through a scanner and in a second or so it has a complete list of all the id's in the cart.
0.3 If the intended use is to verify Amazon (for instance) why do browsers NOT automatically alert you if the Certificate has changed since the last time you were on the site. (I don't care if it is from a valid authority, i care if it has CHANGED.)
Under Canadian law it was LEGAL to rebroadcast television without permission. That is how the cable companies in Canada started operating in the first place, but now that they are entrenched and everybody is happy with the status quo they flipped the decision when it is applied to the internet.
(by the way, it was perfectly legal to rebroadcast via radiowaves, so geographical local was irrelevent.)
But don't worry, regulators don't read legislation anyway.
Even if this was a full trial the press can be banned from publishing details.
But, so what? The ban is lifted at the end of the trial, and, as you mentioned, the public can attend.
And, having read the accounts in the American press of the Bernardo trial I can't say that it bothers me the banned publication till afterwards. (And, having read the Canadian coverage afterwards it was much LESS sensational and a lot more appropriate coverage.
If you want to argue that Seti looks at the wrong range in the electromagnetic spectrum, do so. If you want to argue that there are methods of communicating which would be extreemly difficult to pickup by any method we currently have available feel free.
I don't personally hold much hope for SETI, for a variety of reasons, and yet I suport the endevour.
(Ultrawide band transmissions would for instance be almost impossible for use to pickup, we would see it as background noise at best.)
A carefull analysis of the radio spectrum would revela that SETI looks for singals in the promising ranges and that any aliens wishing to communicate could also determine that these choices would be good.
Remember, a civilization which is technologically equal to our own could theoretically cmmunicate with us, it would not HAVE to be more advanced than us.

yeah, whats a few Canadians between friends...
Yeah, I was a student at RRCC back in the early ninties, ran into the same problem on multiple occasions.

Yes, thats right, you plug the car into 110V to power a heater which keeps the oil from turning into molassis. Thats so the engine car actually start the next day.
And yes, some people do have battery warmers.

:)
yeah, just love Winnipeg transit.
Glad I have a car.
So, do you really think CNN puts people in front of the camera?
Come on!
The first is for the techies, the second confirms that it works with your operating system.
Somepeople will always ask for confirmation.

This reduces, but does not eliminate the risk.
While this shuttle was old it was just back from a refit.

My condolences to the families as well.
Another possibility is your power company.
Seriously. If you and your friend get power from the same place it is possible there is a problem. Say, 130V AC instead of 120... etc.
And, it could just be fluke. And, after several years hardware will fail.
fact of life.
Of course people could just learn how to drive.
(driving 10ft off the bumper of the car in front is dangerous, driving 10ft off the dumper of the car in front in snow is suicidal.).
actually, just make the keys to the work expire.
The keys go to a third party and are released on a specific day.
groups like Drink'or'Die will do it regardless of the monetary incentive.
It's a rebelion thing.

I did not say one was already designed for it.
But there is nothing in the specifications which makes it unbelievable.
For instance, it is quite possible to photograph a tire at that distance and analys the image of the tire. (yes, STOPPED, without bluring from the speed.).
I've used barcode equipment that does a much better job that your average. (about 1.5-2ft reading distance).
There is a very wide range in ability in barcode equipment based mostly on price.
I think the RFID would be more reliable. But barcoding at that speed is quite possible.
No.
It isn't relevent if the RFIDs can hear each other.

why can't you scan a barcode thats moving?
Just point a steady laser where you expect the barcode to be and detect it. No scanning laser required.
(I will assume the barcode is SOMEWHERE it can be scanned from the side...)
I believe I read an article only 2 years ago about how cheap it was to buy the full license plate database from Texas motor vehicle department.
(I think it was Texas, I could be mistaken.)
