Its a fair point, but the BBC world service on radio always announces the time in GMT (pointedly not using the French UTC), so it is sort of appropriate for the BBC web site to also report the time.
But a micro SD card can store four gigabytes of key data now, which should be good for the life of the system, so maybe the next step is to embed a one time pad in both the key fob and the car security system.
Erm... I don't think this would be necessarily a good idea. If you move out of range of the car and use the fob, you can record a copy of the next key that will be used in the sequence, and then broadcast it back. Not only would that allow you to unlock the car, but it immediately borks the key fob as well....
But surely its a challenge response thing:
key -> car (lets talk)
car -> key (random challenge number)
key -> car (challenge combined with key)
In this case the challenge would be an index into the array of key values stored at both ends.
Presumably the way this works is that the car and the key fob are loaded with an algorithm and a short key. It is possible by brute force to find the key, given a recording of a few transactions and knowledge of the algorithm.

The problem with Agile is that it gives too much freedom to the customer to change their mind late in the project and make the developers do it all over again.
Yeah this part bothers me a bit. Nuclear bombs generate radiation, which heats the air and pops eardrums, etc. The best it can do at an asteroid is vaporise part of its surface, so the impulse from the bomb isn't going to be all that fantastic and most of the energy will be wasted. Makes me wonder of a real nuclear rocket is required.
Its an interesting question. I sometimes hear voices as a result of epileptic seizures but they are invariably replays of common things which I hear, like a close relative saying "don't forget the milk" or some such.
I have read elsewhere that servicing the Model S means topping up the wiper fluid and rotating the tyres. Braking is done mostly with the driveline. Suspension generally lasts the life of a car these days. Electric motors are super reliable. Single speed gearboxes are reliable, like a differential gear. You basically build it and never touch it again.
If electric cars take over the market, the demand for car maintenance will collapse. Thats a big chunk of the job market in some areas and there will have to be some adjustment.
We should all have such problems. Also if they find the cure for cancer, a lot of oncologists will be out of a job. It's still a big net win for society in either case.
Thats right but mechanics will still complain and vote for measures to preserve the status quo.

Ping and divide by 2?
Thats the problem.
Yes, also the BBC shortwave services.
Siderial time or maybe julian dates.

GMT and UTC are important time references globally. I can see value in using them. And anyway, GMT isn't always local time in the UK.
Not seeing it here in Australia. Maybe I have to browse anonymously.. or maybe us Aussies are being cut off at last. No more allowance from auntie!
BBC should just display GMT.

A friend of mine built his own, simple alarm system. The alarm sounds when a door handle is pulled. He reasoned that most thieves will try that first.

Why not? If anything the problem is the branching strategy.

One big advantage is to remove emissions from dense urban centres. Thats a big plus for the people who live there.

Nexus 6, right?
Any object small enough to be destroyed this way would be best avoided by evacuating the locale where it is going to hit.
Its the same for ARM. Java doesn't run properly yet because of the floating point limitations of ARM.
With sufficient abstraction.
My all means use a nail gun. Anaconda sell spear guns too.
...is harder to get in Australia so improvised weapons are not going to be as much use as in the US.
Thats a UK thing, right? With a Tesla it could probably be done remotely, with software.
