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 . You can reach me via email at charlie@charlielandau.com .
