Well the TFA title was Lithium-Ion Batteries. . . , so the word "ion" should be a clue that Li metal is not *supposed* to be involved.
The link you offered specifically says, "Note that this is only true of new, unused disposable lithium batteries." i.e. not rechargeable Li-ion or Li-polymer cells.
I guess some elemental Li can form if the batteries are overcharged but this should be prevented by the charging circuitry.
Lastly, the electrolyte contains an organic solvent that presumably could start to boil if the temperature gets too high, causing a rupture.
And, as someone else mentioned, Li hydrides will react spontaneously with water or moist air, so the puncture theory is reasonable.
LiAlH is used as a powerful reducing agent in industrial and laboratory organic reactions. Nasty stuff.

I bought a Wacom graphics tablet for $80 ($100 minus $20 mail-in rebate) and got Photoshop Elements 3.0 bundled with it, making it essentially free. And there are workarounds to let you do things with PS Elements (like masks) - those things that Adobe disabled in Photoshop to make it Elements.
IIRC, PS Elements 4.0 has more features disabled than 3.0, so try and get the older one if you can.
I certainly did not say "no data above 4 kHz".
No doubt there is a significant perceptible difference, it's just that in terms of *intelligibility* (what really matters for a voice phone call) there isn't THAT big a difference between 8kHz and 16kHz, certainly not a doubling.
Put it another way, if 95% of listeners can understand a sentence uttered by a speaker at the other end at 8kHz, maybe 96% can understand at 16 kHz. And yes, I just pulled those numbers out of my posterior, but hopefully you get the idea I'm trying to impart.;-)
For music, I'd agree that the difference is much more important.
. ..and I wouldn't call it a doubling of quality. The improvement of adding one octave of high frequency is, subjectively, less than a doubling. A human voice is quite intelligible with no frequencies above 4 kHz or so present.
You're probably right, but I thought I'd mention that one of the author's names I recognized as a top-notch mathematician: Andrew M. Odlyzko. I read about him in a book about the race to prove the Riemann Hypothesis.
I'd say he's a pretty smart guy - I don't about practical or "street" smarts - but some smart people don't value money so highly.
I've heard of two of them: David Pogue and Andy Ihnatko (sp?) because they've written magazine articles in popular Mac magazines.
I used to be a Mac fan but have to use a PC at work and can't afford to buy the latest Mac for myself - I probably would be still if I did.
I do have an old G3 PowerMac at home, but hardly use it.
If parent is a Mac user, I'm surprised he hasn't heard of those two, at least.
This is Oregon. You don't have to to have any reason whatsoever to let people go. It's an at-will employment state, meaning neither employees nor employers have any right to expect any sort of obligation from the other. Two weeks notice is nice, but even that's not required. The only chance a terminated employee has of legal recourse is in a clear case of employment discrimination, and there are inly a few cases that meet the requirement (i.e. age, religion, sex) and it has to be clear. For example, if they let 1000 people go and they're all over 55 and all the other people in equivalent positions who are under 55 stay, that's pretty clear.
I know for example, that they're combining two groups - FMO (Fab Materials Organization) and FMSO (Fab Materials __ Organization)- into one group - GFM (Global Fab Materials) - and eliminating the redundant positions between them. But there's nothing legally preventing Intel from getting rid of what it considers relatively poor performers.
Now Santa Clara may be a different situation entirely.
Probably the P intended a different meaning - one that would be clear had he/she(yeah, right!) written two sentences instead a run-on sentence (i.e "I hate them. Because of that incident. . . )

I read on a theoretical physics blog (yes, there are such things) that there is a fear that this LHC might actually generate black holes.

It was kind of fun to look at the drawings for the patent app on the USPTO website (http://tinyurl.com/zc83g) and see the phrases "Network Pump sends message to the high wrapper" and "High wrapper sends ACK to the Network Pump". Just change a few letters. . .
But to say "not having a father" == criminal?
As someone else pointed out, that's not what I said, but I'm sorry if you took offense nonetheless. Just the same, it doesn't justify name-calling.
When I say "single most significant factor", I mean that an Analysis of Variance (ANOVA) shows that it more significant statistically, than poverty, race, education or any of the other factors examined, i.e. those "hidden variables" that you mention are considered. I didn't say anything about causation either. Of course, children can overcome poor or non-existent parenting, but it's an added burden that makes it less likely, not impossible, just less likely. Likewise, children of parents who do everything right can turn out poorly, but it's less likely - and yes, I did read Freakonomics and I have some disagreements with the author's methods and conclusions, though the book did have its interesting and entertaining parts.
I remember vividly standing in line and getting pneumatic injections in Navy boot camp - that was 1986 (ooooh, just dated myself).
Yellow Fever vaccination was particularly memorable as it made me really sick for just 24 hrs., then I was fine. They told us not to move as we were getting the shot as it would rip the skin and be much more painful.

OK, but see my comment above #15734168 (not my first comment)
The current story involves rechargeable Li-ion batteries that don't contain Li metal.
once the environmentalists find out they'll make sure we can't get them - mercury is toxic after all.

Heck, I've (inadvertently - of course) done that with NiMH batteries and gotten a "hot pocket" real quick!
That would be a plausible explanation if the battery contained elemental lithium. They don't. They contain compounds of Li.

Don't know how it compares to Switzerland but Portland, OR is pretty bicycle-friendly. I don't take advantage of it much, sorry to say.

Not so much, but AMD still doesn't have larger market share than Intel - not nearly. It's just that the gap is shrinking.

What, like getting a vasectomy, changing your mind, and then finding out it's irreversible?
It seems more likely this is an attempt to render men unnecessary - like that's working out so well now.
Any idea on what is single most significant factor in determining the likelihood of a child ending up in prison?
That's right: whether or not the child had a father around.
