The only radioactive isotope of carbon is C14. The amount of C14 versus C12 is roughly 0.0000000001%. That is one part in one trillion. A human body has roughly 80 trillion cells.
So 80 of your cells contain *ONE* atom of C14.
Your whole body contains 80 C14 atoms
No. An 80-kilogram person has about 14 or 15 kg of carbon atoms. This works out to trillions of carbon atoms per human cell. Therefore every cell has approximately one atom of C14, and the human body as a whole has almost a quadrillion C14 atoms.
On Linux and probably some other unices, chroot is not intended for use as a security mechanism. See http://it.slashdot.org/story/07/09/27/2256235/when-not-to-use-chroot and also man 2 chroot.
If you can take the performance hit, a VM of some kind (emulated bytecode, virtualization or JIT compilation) is much better for security. Unfortunately, security is more difficult than it seems at first glance, so it doesn't always get the attention it needs. Hence we have gaping holes in Java applets. This is why we can't have nice things.

there was an IWW member (Industrial Workers of the World for anyone unfamiliar -- aka "wobblies") standing on a street corner doing nothing but publicly reading our own Declaration of Independence. After a few minutes, a police officer comes by and arrests him
That was Frank Little.
"zero-gravity" is usually used synonymously to mean effective weightlessness, neglecting tidal effects.
So, yes, there is plenty of gravity acting upon satellites in orbits, but they are in free fall, so there isn't a significant gravitational force experienced by the components of the satellite due to their accelerating reference frame. Thanks to our somewhat sloppy terminology, this is zero-gravity.
Call me curious, but what does Yahoo! offer these days besides a buggy version of Gmail and Flickr?
Yahoo! Answers, which admittedly is very hit-and-miss, but sometimes it gets the job done.
Humans work with base 10 [ten] for good reason.
What reason(s)? All I can see are:
- Because we have ten fingers and ten toes,
- because ten is a product of two and five making division by these two numbers easier,
- and simple momentum (it's too late to change now).
I personally think that hexadecimal is a superior system, especially for communicating with binary computers which use binary naturally. The only reason we can't use it is because we decided that ten was a great number base for some reason.
