A service may be provided that reads sensors, and that communicates information based on the sensor readings to applications. In one example, an operating system provides a sensor interface that allows programs that run on a machine to read the values of sensors (such as an accelerometer, light meter, etc.). A service may use the interface to read the value of sensors, and may receive subscriptions to sensor values from other programs. The service may then generate messages that contain the sensor value, and may provide these messages to programs that have subscribed to the messages. The messages may contain raw sensor data. Or, the messages may contain information that is derived from the sensor data and/or from other data.

A component instance manager of a database system generates an instance of the application function. The component instance manager then generates an executor for the application function, and requests an instance of a component class of the application function from a package manager of the database system.

The application function is thereafter executed by the executor according to the runtime parameters.

Techniques are described for utilizing synchronous APIs which normally block callers until a result is returned. In particular, the techniques described herein enable an application or other programming construct to boost performance by executing synchronous APIs (e.g., long running time APIs) within a proxy container rather than executing the synchronous APIs in the context of the application itself. Since the proxy is a separate process or thread, the caller application is thereby released from waiting for the synchronous API call and may proceed with other processing instead of waiting for the synchronous API to return. The application may then monitor the proxy to determine whether a result has been received, such as by periodically polling the proxy.

Communication facilitated between frames of a browser window. Whenever a particular frame receives a message destined for a target frame from a source frame, the particular frame determines if the particular is indeed the target frame. If so, the particular frame processes the message, but if not, the particular frame determines whether the target frame has registered with the particular frame. If the target frame has registered with the particular frame, the particular frame uses a handle communicated as part of the registration to dispatch the message further towards the target frame. In some cases, this handle may be directly that of the target frame itself, in which case the particular frame communicates the message directly with the target frame. This manner of inter-frame communication may be facilitated by a unique registration process when frames come into existence.

Through an asynchronous callback enhancement, a thread makes a non-blocking request (e.g., send, receive, I/O) to a message passing interface library, and a callback routine is associated with the request as an asynchronous callback to the thread. The callback is queued for execution in the requesting thread and so has a deterministic execution context.
