Technologies are described herein for event delivery and stream processing utilizing virtual processing agents. Upon receiving an event publication in a queue, a runtime system identifies one or more virtual processing agents that might be interested in, but have not explicitly subscribed to, the published event. Event information of the published event is then delivered to the identified virtual processing agents. Prior to the actual delivery, the runtime system further determines if the virtual processing agents have been activated and activates those processing agents that have not been activated. Based on the received event information, some of the virtual processing agents might decide to explicitly submit subscriptions to receive more events from the queue. The explicit subscriptions will trigger the runtime system to deliver the subscribed events to the processing agents, which might include past events that have been published in the queue before the explicit subscription is received.

Stream processing utilizing virtual processing agents

A motion desktop, including a moving image, may be presented on a display screen of a processing device. Foreground items such as, for example, icons and associated text, or other information, may appear on a surface of the motion desktop. In embodiments consistent with the subject matter of this disclosure, foreground content may be rendered to a composing surface, which may be an alpha-enabled surface capable of presenting translucent items. A motion desktop module may render content for at least a portion of a background of the motion desktop to a respective shared memory, shared with a composer. The composer may periodically copy the rendered content from the shared memory to the composing surface, where the composer may compose and blend a scene from background and foreground content. The composed scene may then be presented as the motion desktop.
