Comment Re:Christmas is coming early this year (Score 1) 702

If the measures were actually successful, the TSA should be tooting it's own horn. From what I can tell all of the bombing plots in the 2000s were avoided by either misfires or security measures in place since the mid 90s. Also 50g of PETN in a shoe bomb would have been ineffective even if it had detonated.

So putting "non-existent" as a criteria means that you will always fail.

That is exactly my point. Security does not have to be perfect to be valuable.

And you will never know if the money being spent is not being wasted because there incidents are so rare already.

There are many places where traditional methods of statistical research will fail. This is one of them. Instead we have to learn from our experience. For instance: some incompetent people were recruited to light bombs in their shoes - now shoes go through the x-ray machine. People found a way to mix the explosives behind security - now we can't have substantial amounts of liquids. People hijacked airliners with box cutters - now we have reinforced doors and pocket knife restrictions.

Now I'll concede that it is entirely possible that this latest regulation is based upon some scenario in some bureaucrat's mind. It is also possible that, like the liquids regulation, it is done for a perfectly good reason. Only time will tell.

None of the regulations you cited are actually reasonable. The vanishingly small amount of security we gained is not worth the large amount of freedom we've given up for it.

Comment Re:Age of the earth (Score 1) 98

Curious that within two separate articles about the age of the earth, no estimate is given at all. The only mention of an actual age is given in a footnote to the sciencedaily article (which says the earth must be younger than ~4.6 billion years).

http://en.wikipedia.org/wiki/P...
About 4,533 million years. So I'm guessing the new estimate would push it to ~4,593 million years.

because in the entire history of the planet, there will always have to have been at least one species who was a) the most intelligent at the time and b) the most intelligent to have developed up to that point.

I think you mean or, it is possible for a species to go extinct that satisfied both a) and b), leaving the second place finisher to satisfy a), but not b).

OK, I think I misread. A different way to read it would be that even after a species is extinct, they continue to hold both a) and b) records until a new species evolves that beats them. I'm not sure what to make of the argument, though.

Comment There may be some problems (Score 1) 228

Shopping on the Internet is quick and convenient, and international. Using a credit card, charges appear as if you had made a purchase from wherever their merchant account lists as their address. In general, your location (as provided by your IP address) is not taken into account. This has already caused me problems with an overzealous bank that doesn't believe I would be shopping in Germany or Japan. Now if they can see that I'm obviously still in the US (via my cellphone), well then.

Speaking of name changing, what if you're on the no-fly list and then you go change your name? Does the no-fly list get updated with your new name? I can't imagine so.

Change your name with whom? If you change your name with a government that has your name on a no-fly list, then I would think they would keep it up-to-date.

I'm actually curious where you got the information from. The linked articles from Wikipedia don't mention specific materials, with the exception of one. That material is specifically C.H3.N.H3.Pb.I.Cl2 (starting from C.H3.N.H3.I and Pb.Cl2), which falls within your broader categorization.

If you're stranded 100 miles from the nearest charging station, it means you didn't pay attention to the fact that your car wasn't fully charged before you drove off AND you didn't pay attention to the dwindling charge as you drove. This isn't a Tesla failure.

We do not know if the car was fully charged or not.

Also, I could be mistaken, but I believe the Tesla only reports the expected range not the charge level.
