Setting aside the fact that this is just clearly a marketing campaign that doesn't really care about environmental issues and such, the environmentalists are just too stupid to recognize that paper is a carbon dioxide SINK. Paper is produced from low-grade fast growing trees and if we stop doing that, simply less CO2 will be absorbed from the atmosphere.
> The innovation in the Alabama system was to use waste heat in the turbine's exhaust gases How is this innovation? It's been used in the Huntorf CAES since 70's. Basically, it's a natural gas powered plant, which gets its oxygen in form of compressed air, which saves a lot of energy that would be needed to compress the air at the gas turbine intake. It also uses the exhaust heat to pre-heat the air.
Still, the losses are quite massive: 1 kWh of recovered electricity is produced from 0.8 kWh stored electricity and 1.6kWh gas. 1.6 kWh is the thermal value, not electric. In a normal gas power station you can generate around 0.8kWh el from it (50% efficiency gas turbine), so basically the 0.8 kWh that was stored in the CAES contributes only 0.2kWh to the output, you recover only 25%.
So, this battery is supposed to be able to power an entire one-family home for a week. By a conservative estimate that would be around 100 kWh of capacity. Modern Lithium-Ion batteries have specific capacity of 100-160 Wh/kg, but let's say Panasonic manages to extend this and will deliver 200 Wh/kg. Let's assume the half of this weight is Lithium, which puts the total Lithium weight for such battery at ~1000kg. With a total world's estimated Lithium reserves of ~11000000 tonnes we can outfit around 11 million homes with such batteries before we run out of Lithium. Sounds like a solid plan.
What's more important: I thought this section was already warmed by 100 degrees? Why they have to cool it down again and then wait another X weeks to warm it back again to room temperature. WTF
When you go out of the country, just yank the battery out.

If you got hit by java full-screen pop-up:
1. press Ctrl+Alt+F1
2. find java_vm process with ps -efa | grep java
3. kill java_vm process
4. return to desktop with Alt+F7
Will operating systems stick with current user/kernel/process/thread principles, or will there be some other concept to allow higher parallelization and/or different security model in the future?
Looking through their APT repository I'd like to ask : they're still using XFree instead of Xorg? Just switching from XFree to Xorg made my "Applications opened almost instantly" without any prelinking. And v6.8.0 just added to this boost. What's the point of compiling an ultra-optimized system and then using an obsolete software on it? Sometimes much more performance can be obtained just by upgrading your software.

Well, at least they patch them.

Now that Pluto is no longer a planet, why is it still included in the message? Shouldn't they be sending an updated version?
How to easily make your code compliant with the new safety requirements:
#define memcpy(dest,src,len) memcpy_s(dest,len,src,len)
I don't get it... How operating all wireless networks in unencrypted, unauthenticated mode is supposed to provide Net Neutrality?
Shouldn't a network with 200 wireless clients be considered ... ummm ... an "enterprise"? Rings a bell? No? RADIUS? EAP?

You shouldn't just throw Cadmium Telluride into the ocean. Because one day it will return to you in the fish meat.
I'm in Germany: youtube.com can be resolved, but traceroute to 208.65.153.253 fails from Arcor network.
Works fine through DFN though.

You certainly mean "256x192x2 pr0n, w00t!", right?
Oh really, which country do you come from, where porn of persons over 15 is legal? (as opposed to 18 everywhere in the world)
Wasn't Core architecture found eating about as much as AMD, considering that AMD CPUs include memory controller, and Intel has it on the Northbridge?

The funniest part will be where the rocket malfunctions and buries all the junk in the ocean instead.
P.S. zOMG
hauling things to the geostationary orbit is quite expensive in general, it's almost 1/10 of distance to the Moon.
