At the same time, people continue to treat fire as an event that needs to be wholly controlled and unleashed only out of necessity, says Professor Balch at the University of Colorado.

As the GDM code says, "it's hard to be event controlled while maintaining state," so we add our own state-monitoring variables and data structures to process the keystroke-dynamics functions.

You are allowed controlled access to the host system's hard drive in the event you need to offload pertinent data from an otherwise "dead" machine.
