Composable system

A non-transitory computer accessible storage medium storing a plurality of instructions which are computer-executable on a computer, wherein the plurality of instructions comprise:

• a plurality of capabilities, each of the plurality of capabilities comprising at least one function that is computer-executable;
• a plurality of actors, each actor associated with one or more capabilities of the plurality of capabilities, and each actor computer-executable to implement a respective part of an operating system for the computer;
• wherein the plurality of actors intercommunicate using messages transmitted via channels between the plurality of actors, wherein a first actor of the plurality of actors receives messages on a first channel from a second actor of the plurality of actors;
• and
• wherein the second actor is assembled from a plurality of the plurality of actors, and wherein a third actor of the plurality of the plurality of actors receives a channel identifier for the first channel from the first actor and passes the channel identifier to a fourth actor of the plurality of the plurality of actors to communicate with the first actor, wherein the fourth actor transmitting a message on the first channel causes an activation of the first actor.

A non-transitory computer accessible storage medium storing a plurality of instructions which are computer-executable on a computer, wherein the plurality of instructions comprise:

• a plurality of capabilities, each of the plurality of capabilities comprising at least one function that is computer-executable;
• a plurality of actors, each actor associated with one or more capabilities of the plurality of capabilities, and each actor computer-executable to implement a respective part of an operating system for the computer, wherein a privilege level of each actor is a minimal amount of privilege that permits the actor to implement the respective part of the operating system;
• and
• wherein the plurality of actors intercommunicate using messages transmitted via channels between the plurality of actors, wherein a first actor of the plurality of actors receives messages on a first channel from a second actor of the plurality of actors and the first actor specifies which messages the first actor will permit on the first channel when the first channel is created, wherein the isolation of each actor from the plurality of actors via the channels and the minimal amount of privilege accorded each actor improves security in the system.
