Debain/Ubuntu Linux Headers - 3Steps

Installing kernel source with apt is just so simple-
$>sudo apt-get update
This will update information from the apt repository.

$>sudo apt-cache search linux-headers-$(uname -r)

This should return the name of the package with the
current kernel headers along with a short description.

$>sudo apt-get install linux-headers-$(uname -r)
This command will install the kernel headers.

Why does a car slip on thin ice in winter?

Because the thickness of ice/layer of water should
be only so much that it reduces the coefficient of
friction between the wheels and the road to zero (or small
enough), while not introducing friction due to its
own thickness.

Interesting huh?
