摘要:
One or more application programming interfaces (APIs) are exposed by a host program running on a device to facilitate a control program displaying content in a window in which the host program displays content. As part of an API, a method is exposed that the control program can invoke to pass to the host program a definition of a surface presenter to be created by the host program. Additionally, the control program can store content that the control program desires to have presented in a buffer of the surface presenter, and invoke another method exposed as part of an API to pass to the host program an indication of the content that the control program desires to have displayed in the window in which the host program displays content.

In one or more embodiments, an application program interface (API) is provided and enables an entity, such as an application, script, or other computing object to register to receive callbacks immediately and, without specifying a time constraint. In this approach, the API does not rely on a timer, such as a system timer. Rather, a non-timer based queue, such as a message queue-type approach is utilized. Specifically, callbacks that are registered through this API can be placed on the message queue and work associated with the registered callback can be performed through the normal course of processing messages and events in the message queue. Over time, such results in a callback pattern that allows an associated web browser and applications such as web applications to remain responsive, while increasing performance and power efficiencies.

In order to provide a more efficient persistent storage device, one or more long-term storage media are included along with a non-volatile memory. In one embodiment, one portion of the non-volatile memory is used as a write buffer and a read cache for writes and reads to the long-term storage media. Interfaces are provided for controlling the use of the non-volatile memory as a write buffer and a read cache. Additionally, a portion of the non-volatile memory is used to provide a direct mapping for specified sectors of the long-term storage media. Descriptive data regarding the persistent storage device is stored in another portion of the non-volatile memory.

Virtual surface techniques are described. These techniques include support of initialization and batching of updates, use of updates and lookaside lists, use of gutters, blending and BLT operations, surface optimization techniques such as push down as well as enumeration and clumping, mesh usage, and occlusion management techniques.

Profile data can be ascribed to groups as a function of an organizational scheme that defines groups and relationships between groups. The groups can be abstractions over profile data that are meaningful for computer program analysis. Subsequently, grouped data can be disseminated, queried, and visualized in numerous ways to further aid program analysis.

In one or more embodiments, a framework is provided in which image decoding can be delayed based on heuristics, and later initiated based on a use type associated with the image or the likelihood that the image is going to be used. For example, a use history and priority system can enable images that are currently being rendered and/or are likely to get rendered to be decoded before images that have a history of being downloaded but never used. Accordingly, by decoupling image download from image decoding, CPU resources and memory can be more efficiently utilized.

In a method of synchronizing with a separated disk cache, the separated cache is configured to transfer cache data to a staging area of a storage device. An atomic commit operation is utilized to instruct the storage device to atomically commit the cache data to a mapping scheme of the storage device.
摘要:
A system for reporting and analyzing problems encountered by computer users. The system includes a recording tool executing on a user computer to capture a sequence of user interactions in the context of a graphical user interface. When a problem or other stop event is encountered, the tool generates a report indicating user interactions leading to the stop event, including information such as the specific sequence of controls for specific programs accessed by the user. The report can be analyzed to identify a sequence of user interactions characteristic of a problem type, which in turn may be used to find a solution for a particular user's problem. The system may also include a server that receives and analyzes reports from multiple computer users to identify patterns of user interactions that characterize problem types. This information may be used for associating specific problems with future reports or to improve products.
