    otro motivo más para no usar mysql. en postgir, ST_Contains(A, B)
devuelve:

Geometry A contains Geometry B if and only if no points of B lie in the
exterior of A, and at least one point of the interior of B lies in the
interior of A. An important subtlety of this definition is that A does
not contain its boundary, but A does contain itself.

(Not so) Random fortune:
The technology industry sees itself as in rebellion against corporate
America: not corrupt, not buttoned-up, not empty. In fact, a tech company
can be as corrupt, soulless, and empty as any corporation, but being
unprofessional helps us maintain the belief that we are somehow different
from Wall Street.
