Freebsd Murphys Law

Systems should not be unnecessarily multiplied.

Systems tend to grow and as they grow they encroach.

Complicated systems produce unexpected outcomes.

The total behavior of large systems cannot be predicted.

A large system, produced by expanding the dimensions of
a smaller system, does not behave like the smaller system.

People in systems do not do what the systems says
they are doing.

The system itself does not do what it says it is doing.

A complex system that works is invariably found to have
evolved from a simple system that works.

A complex system designed from scratch never works and
cannot be patched up to make it work.  You have to start
over, beginning with a working simple system.

(1)     Everything is a system.
(2)     Everything is part of a larger system.
(3)     The universe is infinitely systematized both upward
        (larger systems) and downward (smaller systems).
(4)     All systems are infinitely complex.  (The illuison
        of simplicity comes from focussing attention on
        one or a few variables).
