Having run computer systems for a year in Antarctica at over 10000ft altitude, I wish them well... I've had lots of problems with:
difficulty in cooling systems: the thinner and dryer air means than there's less evacuation of heat. Meaning you need to run your fans at higher speed, meaning they don't last long. I exhausted all my spares halfway through. Your disks and CPUs run at higher temps, which is particularly hard on the disks.
problems with hard drives which I have no proof but wonder if the head floating on air is closer to the surface, inducing damage to the surface. I never understood why hard drives (even the latest 4Tb which I hold in my hand right now) have a 'do not cover' hole to let air in. Why don't they seal them ?!? I lost all my spare drives.
problems with thermal fluctuations: power goes out, temperature drops to -40 in an hour, power comes back, PC tries to boot automatically, hard drive with deformed platters screams in pain...
Sorry but I don't. I was there during the aforementioned Epica beginning and end, but I'm no glaciologist so that's pretty much the limit of my knowledge. Anyway good datation crosses the different methods AND different geographical origins: dendrochronology, ice cores, lake cores, deep ocean cores, historical archive (wine production, solar spots...), historical artifacts (sealed glass bottles)...
iOS devices ALSO do not allow installation of apps to external media which was already a monstrous security hole for Android devices; any SD card inserted that was formatted FAT32 could have any portion read and written to by any app.
Yeah, as opposed to Apple's solution of not putting ANY SD card reader in the first place. Much more secure. Right on.
There's plenty of papers about them, but they give different scopes. Usually Antarctic cores are more precise and less sensitive to random fluctuations. They also measure more things (temperature, humidity, direct CO2 levels...). In the case of TFA, a 40m core is less than impressive if you compare it to 4km long cores from Vostok or Concordia, but the gist of the article is that it will be very precise for each year.
Yes, because you can't do what you just said. Water has the (un)fortunate effect of reacting with almost anything it gets in contact with: CO2, metals, viruses suspended in air, deposits on glass surface even after they've been cleaned with acid and liquid O2, etc... and absorbing it. The water in the lake is purer because the only thing it comes in contact with is pure ice (and there's probably some segregation process going on inside). Anyway I was at a conference with the guys who are trying to analyze that water from the lake without contaminating it and they say it's NOT easy. They are designing a lab around the issue.
They've been drilling more or less inside the same hole (there are a few deviations due to stuck drills) since 1959 with a bunch of years off for lack of funding.
Well, technically the russians haven't quite breached the lake. It's ongoing right now and here's what I've followed so far:
The layer of ice just above the lake is refrozen water (and not compressed snow from above). They already analyzed that without finding anything significant (a US lab found lots of stuff but the word is that it's all contaminated DNA, a french lab found only one candidate piece of DNA, that ice is 10 times cleaner than the cleanest water we can make in a lab).
So a few days ago the russians breached the last remaining ice after using a sterilized drill. They then withdrew the drill and immediately lowered the pressure of the drilling fluid, allowing the water of the lake to raise into the hole for 600 meters. This water froze quickly. Now they are drilling again this freshly frozen ice which will be analyzed in a special very clean lab. I just don't know how they can drill again 600m of ice without deviating more than 10cm (the diameter of the core).
Official results should start coming in about a month.
Yeah, the whole of France learned about porn from the Minitel in the 80s, a 300 bit per second dumb terminal with 'advanced' ascii art. Advanced as in 'there are graphic characters with 3 lines and 2 columns of squares that you can use to fake graphics'. It took a lot of imagination, but that beast was turned off only last summer.
Yea, right. Look around you how the massive improvements in productivity (industrial, agricultural, etc) is distributed... Does it look like it's split evenly among everyone ? No: a very few CEO/owners of a few large companies reap all the benefits and charge 'what the market can bear' on everyone. What makes you think that this method would change with the advent of robots ? You'd have to pay everything you _can_ to benefit from those robots, even if their production and running costs are minimal.
As a regular flyer I honestly cannot believe how many people will either intentionally disobey, or are completely oblivious, when they're asked to turn off devices and bring their seats up, etc...
I put my headphones on during take-off BECAUSE it's the noisiest moment. The active noise cancelation is a blessing. And for the rest of the flight as well.
It's already in The Crystal Spheres a short story by Brin where a starbound asteroid breaks the solar 'barrier'; and a very good but bittersweet comic book "L'autre Monde" by Rodolphe-Magnin which I believe also has an english edition.
I've eaten one year old yogurts and eggs (raw too). One out of 3 yogurts would blow in your face upon opening, and one out of 3 eggs was black evilness. The eggs were waxed and irradiated to keep them for so long. It was in Antarctica and since then I've stopped reading date limits.
Thanks for the detailed explanation, I've never read that before.
When I asked about different segregation methods, I was thinking along the line of the formation of the Earth+moon from the collision with a bigger thing than the moon. If before that both bodies had a very 'standard' segregation process (heavy elements at the core, lighter ones at the crust), I bet that after such a collision a lot of heavy elements were to be found on the surface, unless everything melted and dropped to the core again.
I mean - hey. When working in France, I had a 2,5-hour lunch break to enable the liver to do salutory ethanol-breaking-down work. A job at Samsung HQ, however, sounds even more interesting.
Even that is beginning to change. Restaurants in France now offer half-bottles, which they resisted for decades. I remember being an intern in some high-tech companies and coming back from lunch at 4pm hammered and getting back to work on software and hardware specs...
I know many americans who simply throw the coins away after each transactions, finding they 'unwieldy'. Or at best they put them in a cookie jar when they get home and convert them when it gets full. I think part of the fault lies with wallet makers who hardly ever include a practical coin holder on the wallets. Since US $ bills are much smaller than most other currencies, so are the US wallets, meaning there's no room for an extra pocket for coins. In Europe I have a big wallet which is mostly flat. In the US I have a small wallet which is almost cubical what with all the credit and membership cards I have to put up with. The former has plenty of margin for keeping extra coins, the latter, understandably, doesn't.

I mean, I build embedded systems and we have problems _finding_ components so archaic. Where do they find them, I wonder.

Huh... What does a seafood restaurant has to do with Antarctica ?

Well, there's probably something to be said to the fact that this morning my yogurt was covered in mold, and it was still a week away from its limit !
Bestiality and necrophilia at the same time.
That sums up Twilight.

Easy: put them on top of an AMD processor !

Personally, I'd rather hang out with some mountain climbers than a bunch of sloppy drunks.
As a hardcore climber and a home brewer, I'm sure there's a compliment in there somewhere, but I'm not sure where.
