Of course the mirrors could be focused to take down overhead aircraft or satellites as well.
No they can't. These plants use parabolic trough mirrors. I.e. you have a row of mirrors, and the energy is focused into a pipe that's suspended in front of the row.
You need both. Solar power is low-density, so you need a lot of area to gather enough power.
When you install PV on rooftops, it doesn't provide enough power for buildings with more than a couple of floors. I did some calculations recently for my own apartment building: a roof full of PV panels provided just enough power for one floor of the building, assuming the national average domestic power consumption.
CSP can supplement power generation for high-density areas (cities). It can also easily provide nighttime power by using heat storage. This is more difficult to do with house-sized PV (you need huge battery banks in each house, or a central storage system, e.g. a pumped water storage facility).
Actual information about the Mojave Solar Project can be found here and here. The technology used in the MSP isn't entirely new (has been used in at least one other plant) but looks to be an incremental improvement. The plant features heat storage using molten salt, and won't be using fossil fuels as nighttime backup.
78 tabs, 1.33 Gb 'real memory' according to Activity monitor. According to about:memory: Memory mapped: 974,811,136 Memory in use: 875,324,896 after 1 day.
I got my figures from Dinorwig, which has 500m of head, and was designed as a day/night buffer. Its storage ponds may not be as large as a conventional hydro installation, but at ~ 1 km^2 each they're not exactly small either.
* Pumped hydro energy storage (works with any type of power; already widespread in China for day/night demand averaging) (does not require a river or a large impounded area!)
Come again? A large reservoir is exactly what a pumped storage plant needs. You need 200 m^3 of water per second to generate 1 GW. In fact hydro and pumped storage have limited application because of the limited number of places where you find a large body of water and a sufficient altitude difference for the exhaust/lower storage pond.
* The natural correlation between solar intensity and power consumption (night is off-peak, sunny days have more AC load, etc - -it's not perfect, but it's a nice start)
That's only true for warm climates. Here in northern Europe (52deg N) AC is less of a factor, and power consumption peaks in the evening and in winter (electric heating).
Sure, not all of them. But in my experience cameras become obsolete long before they stop functioning. At the higher end (SLR) you can expect at least 10 years. Hell, loads of film cameras from 4 decades back still work.
That was my first thought as well. But how are the security goons going to distinguish between e.g. the 2010 Macbook Pro which doesn't have this feature, and the externally identical 2011 MBP which does? Or the iPhone 4.1 with, and the yPhone Chinese clone without? Etc. for all devices on the market.
The billions of existing cameras will continue to ignore such external commands, so the only way to enforce this is to make all of those illegal. That might fly in North Korea, but in the Western world? I know dystopian views are popular here, but I just don't see this happening.
Even individual companies are going to have a hard time, e.g. a movie theatre isn't going to be able to reliably distinguish between cameras with and without this feature, so they'll still ban all cameras.
Will the domain names stay 'seized' forever? Or will the DOJ allow them to be sold at some point in the future, the way other seized assets are sold off?
Apple has generally run their internet services on whatever was available. Sometimes that was Macs (I remember using their FTP server ca 1993, it was run on a Mac IIci), other times it wasn't. ISTR they used a Sun cluster at one point, and around the time of the NeXT acquisition they used Macs again with a server package (WebObjects?) that came from NeXT.
Sure, versioning has been around forever. But autosave, and preserving system state through a restart? I've seen both done on a per-application basis, but not systemwide.
They used more than 2 patch cables. 10 cables were supplied with the machine, and as of 1939, 7-10 cables were used. See e.g. here, which arrives at 10^23 practically possible encodings.
It's strange that an article with that headline says nothing about the postwar period. So here's what's missing.
In the UK, Colossus was kept secret after the war. But the knowledge gained in its construction was used to develop the first British postwar computers (the Manchester Baby, an experimental design, leading to the Ferranti Mk.1 commercial computer). Alan Turing and others who were involved with Colossus worked on the Manchester series.
In the US, ENIAC was commissioned by the Army for ballistics calculations. As far as I can find on short notice, the Americans didn't use computers in their WW2 codebreaking efforts.

It's $2B for these two projects. $30B total, but that includes all 'green technologies', incl. some nuclear power projects and several car projects.

TFT talks about a payment, but if you follow links you end up at this page which talks about loan guarantees instead.

he's not very good at writing English.
We also spend the most money per prisoner annually than any other state in the union.
Yes, I know, cheap shot. Also IDK if school superintendants are usually teachers. But if he is, that doesn't bode well for his students.
Sure, not mentioning its storage capacity is an omission, but quoting the maximum power output is hardly irrelevant or stupid.
Not quite TFA, but here's a report from KEMA (pdf).
According to TFA P2P volume increases, just not as quickly as other traffic.
That's Hibernate, not resume. Look elsewhere in this thread for the difference.
Hibernate preserves system state through a power-down. It does not preserve system state through a reboot.
How is this modded Offtopic? These are features of Lion, aka OS X 10.7, the new OS that will be shown off at the WWDC as per TFS.

Autosave, Version and Resume are major improvements, and long overdue for desktop OSes.
