The document discusses persistent compute objects (picos) that form personal clouds. Picos are online computers that represent entities, store data, respond to events, run applications, and connect to other picos through event channels and APIs. They are part of a technology stack and form decentralized, networked personal clouds for individuals. Picos support a new programming model and ease modeling applications. Challenges for personal clouds include identity, trust, schemas, performance, features, and security. The author invites developers to join the Fuse platform for building applications for personal clouds.

5. Picos are online computers
Identity—they represent a specific entity
Storage—they persistently encapsulate both structured
and unstructured data
Open event network—they respond to events
Processing—they run applications autonomously
Event Channels—they have connections to other picos
APIs—they provide access to and access other online
services
