Professionally, I'm a senior software engineer at Arxan Technologies. Past employers include Palm and Tandem (now HP). My specialty is object-oriented operating systems.

I'm a zealot about capability-based operating systems, one of the originators of the KeyKOS operating system, and the main force behind CapROS.
Here is a good introduction to capabilities.
Here's a design note about an object in KeyKOS and CapROS, the Domain Creator.
A design principle.
Norm Hardy, another KeyKOS guru, has many cogent observations on capability-based systems here.
