the art of drawing lines through countries, disks, and databases so nobody quite trusts the border again.
means dividing a whole into separate, manageable parts, whether that whole is a hard drive, a table, or a nation.
from from latin partiri, to divide into shares; the word did quiet duty in geometry and inheritance law for centuries before the twentieth century made it a byword for maps redrawn in haste.
