A reasonably interesting piece about
Linux kernel improvements, some of the changes in recent kernels and some of the spats and personality politics on the insanely high-volume
linux-kernel mailing list. If you've ever wondered how exactly the
latest kernel you just shlepped home on a ZIP disk and compiled up differed
from the one you had before it, this could be interesting. Anyway, it's good
to know that, at least in Linux kernels, there is such a thing as progress.
