Abstract: Systems and methods of a personal daemon, executing as a background process on a mobile computing device, for providing personal assistant to an associated user is presented. Also executing on the mobile computing device is a scheduling manager. The personal daemon executes one or more personal assistance actions on behalf of the associated user. The scheduling manager responds to events in support of the personal daemon. More particularly, in response to receiving an event the scheduling manager determines a set of apps that are responsive to the received event and from that set of apps, identifies at least a first subset of apps for execution on the mobile computing device. The scheduling manager receives feedback information regarding the usefulness of the executed apps of the first subset of apps and updates the associated score of each of the apps of the first subset of apps.

Abstract: Systems and methods for providing client-side integration of apps and services is provided. An integration framework execution upon a computing device provides integration of various apps, applications, services, sensors and the like. Upon receiving a request for a service, the integration framework accesses a registry of a plurality of services of a respective plurality of providers registered with the integration framework. Each of the services is registered with the integration framework is associated with a trust level of a hierarchy of trust levels. The integration framework iteratively searches the registry for a provider of the requested service according to the hierarchy of trust levels, beginning with the most trusted level of the trust levels to the less trusted trust level until a provider of the requested service is found or until all levels of the hierarchy are searched without finding a provider of the requested service.

Abstract: Evaluating an expression tree. A method includes, at a first domain, accessing an expression tree. The expression tree comprises a plurality of nested expressions. The plurality of nested expressions spans a plurality of domains. The expressions in the expression tree are expressed in a common format in spite of the different expressions of the expression tree being intended to be evaluated by different domains. At the first domain, the method includes evaluating one or more references to local variables included in the plurality of nested expressions. The method further includes determining that one or more expressions in the plurality of expressions are to be evaluated by a different domain. The method further includes expanding the one or more expressions in the plurality of expressions to be evaluated by different domains to allow the one or more expressions to be evaluated by the different domain.
