drooling for drools (jboss webex)

drools

The SkyNet funding bill is passed.

The system goes online on August 4th, 1997.

Human decisions are removed from strategic defense.

SkyNet begins to learn at a geometric rate.

It becomes self-aware at 2:14am Eastern time, August 29th

In a panic, they try to pull the plug.

And, Skynet fights back

Differential Update

Differential Update (a.k.a. true modify)Implements a real modify/update operation, instead of retract+assert.Reuses tuples, reduces GC stress, improves performance
