The total heat produced by radioactivity in Earth is 44.2 TW (Wikipedia).
The total solar power received by Earth by the upper atmosphere is 174 PW (Wikipedia).
This means 3937 more solar energy is received by Earth than produced by radioactivity in its interior.
Furthermore geothermal energy is high entropy energy in regard of solar energy since the temperature difference between
ground (~287K) and nearby space (>10K) (DT=277K) is much less than the temperature difference between
sunlight (5778K) and ground (DT=5491K).
In short the whole idea of converting Earth heat into electricity is completely inefficient in regard of solar energy.
The only way to use efficiently geothermal energy is to find hot spots where it is concentrated by thousands with respect to average.
While the set of large-genomed organisms does include some very sophisticated trees and flowers, it also includes several species of amoeba... so I wouldn't panic just yet.
All a big genome really means for certain is that you're good enough at finding food that you can support it. The substance is a lot more important—some species of shrimp, for example, have 88 or 92 chromosomes, but they're mostly redundant duplicates. Wheat has five copies of every chromosome, too.
Plants tend to have large genomes because they reproduce so rapidly—a field of corn has enough offspring every season to mutate every nucleotide in the whole kit and kaboodle at least once, and because they have very static, slow existences, they can afford to tune themselves very well to their environments. That's what the genes and duplicates are for—giving the plant very fine-grained control over things like how it prepares for the next season based on the weather from the last one.
You can create a file system on a file on your disk (similar to a swap file).
Contrary to popular believe this is not slower than a partition, because if the file is mostly continuous, it can be mapped to disk directly by the kernel. Here I create a file system using a sparse file:
$ truncate +20G mylocal.fs
$ mkfs.btrfs mylocal.fs
$ mkdir -p mylocal; sudo mount mylocal.fs mylocal/
You can use such file systems, for example, to bundle directories with many files, which are deleted/created many times. This causes fragmentation in the file system. Contrary to another popular believe, yes, this is a problem on Linux file systems, and it slows down reads. None of the file system currently has a defragger implemented. Btrfs is actually developing one, but I think it is not in the release yet. The recommended solution is rewriting files (shake).
Sub file system containers can be easily resized, and with sparse files only use up the space filled with data. I use them for the linux kernel build directory (you shouldn't build in
Yes, the example is called Weston.
If it were GPL, every recipient would be required to pass his organs on upon his death. And the organ would perpetually be passed on, because organs want to be free.
Actually not just the organ he received, but all his organs, because the other components require the one received. Although I guess you can argue a generic API.

Hmm
1964 + 25 = 1990, first bump
1964 + 25 + 25 = 2014 new bump?
Maybe this is just the half-time of the shots, and it's time to refresh? I.e. "2014, third dose recommended"
Developing massive attack tools like that make a global cyber war more likely.
As with the initial ICBM's the first one to strike may believe to win.
Very dangerous, and foolish.
20TB is not out of the world. With a RAID of 4TB disks you can cover that at home, and it doesn't need to be on all the time. Maybe you can reduce the amount of disk usage by reducing duplicate content using bup or an appropriate FS.
