How big is big enough that nothing but Oracle will do? Facebook is on MySQL, Wikipedia is on MariaDB and Google is using Bigtable.
It's more the nature and size of access rather than the sheer volume of data. Facebook and Wikipedia both act on small portions of the overall dataset, Wikipedia additionally is a read-mostly workload, and Google's access patterns aren't suitable for a relational database.
I don't know about Los Angeles or San Francisco, but Phoenix's water usage has been dropping as a result of replacing citrus orchards with subdivisions.
There was a brief period (roughly 1993 to 1995) when copy protection worked to stop small-scale piracy: around the time when CD-ROM drives first became popular. If you could stuff a CD full of game files, you had a game that could not be economically pirated, because copying the CD required either a dedicated hard drive to store the data (hundreds to thousands of dollars), a hugely expensive CD recorder (tens of thousands of dollars), or a CD stamping facility (millions of dollars).
The kit includes eight 8 x 8 x 5 inch Enphase inverters weighing 6 lbs each
Which gives a power density of 0.78 watts per cubic inch. The Google challenge calls for a minimum power density of 50 watts per cubic inch.
Starting on page 12 of the report is a series of maps showing the changes since the 2008 report. Of note:
* The South Carolina seismic zone has been displaced southward by about 50 miles.
* The New Madrid zone has changed shape, with some areas seeing a substantial reduction in estimated earthquake risk.
* The risk zones in California are more sharply defined.
* The risk for the central Rocky Mountains area is higher, but still relatively low.
* The earthquake risk estimate for coastal Oregon has been reduced.
* A new seismic zone is present in Oklahoma, reflecting whatever is causing the massive increase in earthquake rates there.
The majority of passenger trips in the US are either less than 50 miles, or more than a thousand, with almost nothing in between. At the short end, the flexibility of car travel beats the cost reduction of rail; at the long end, the speed of air travel beats rail.
The only exception to this is the BosWash area, where -- guess what? -- Amtrak is able to provide profitable rail service. It's not motivation that keeps the US from having good passenger rail service, it's geography.
The random number generator should not be seeded only by a PID.
The PID is used as an absolute last-ditch fallback in the case that no other sources of randomness are available. In order for this to happen,
If you're running on a system that crippled, you've really only got two choices: try seeding using the PID, or use an unseeded RNG. Or follow Theo's advice and get yourself a real operating system.
Soviets made a safety experiment with a nuclear reactor in Chernobyl. It didn't go wrong at all.
Correct. The 1982, 1984, and 1985 tests of using rotational energy of the turbines to power the emergency pumping system all went just fine. The 1986 disaster happened when the operator ignored the test procedure (specifically, the instruction "Reduce reactor thermal output to between 700MW and 800MW. If reactor thermal power output drops below 700MW, abort test and shut down reactor" -- the operator reduced the power to 30MW, raised it to 200MW, and attempted to perform the test).
More significantly, if you see left-to-right motion and say "forward", what percentage do you get right? I suspect there's a bias in videos towards left-to-right motion of subjects (or conversely, right-to-left motion of backgrounds), and I don't see anything in the paper about controlling for it.

Would it have changed the course of warfare? A bouncing bomb that worked at sea would have rendered virtually all navies obsolete.
You know what else can lift a ship and break its back? A torpedo with a magnetic fuse. Oddly enough, torpedo bombers don't appear to have rendered the world's navies obsolete.
I'm sure the NSA has copies. Perhaps someone should request them?
Another candidate is the filling of the Persian Gulf: it wouldn't have been as abrupt as the proposed Black Sea deluge (taking years rather than days), but during the last Ice Age, the Gulf would have been prime agricultural land, at least as good if not better than Mesopotamia. There's a decent chance that there was a civilization there, where the Black Sea would likely have been nomadic tribes.
Sorta important - there's not much popular software that uses GNUTLS, but wget is one of them. Since it's almost always used as a client, it's probably wise to use curl -O against unknown servers, until they get this straightened out.
wget can be built against OpenSSL, and curl can be used with GnuTLS.
How much did it cost to setup their infrastructure to produce these cars? It seems like it would be a loss if they don't sell any at all. Why wouldn't they raise the price?
The electric Fiat shares probably 90% of its parts and most of an assembly line with the gas-powered Fiat 500; it's the remaining 10% (particularly the batteries) that make the 500e so expensive to produce. California clean-air laws require Fiat to sell a certain number of electric cars if they want to do business in California and restrict how much Fiat can mark up the price of the electric version. If Fiat can't get the parts needed for less than the permissible markup, they're required to sell the cars at a loss.
