摘要:
A secure messaging system and method includes receiving an encrypted message, the message having been encrypted using a token of a corresponding pervasive device; wirelessly verifying the presence of the pervasive device; and, if the presence can be verified, decrypting the message using the token. The verification step can include the steps of establishing a wireless link with the pervasive device; and, querying the pervasive device over the wireless link. The establishing step can include the step of establishing a Bluetooth link with the pervasive device. Furthermore, the querying step can include the step of requesting geographic coordinates which locate the pervasive device.

A method, apparatus and program product that determine a density of a key value referenced in a database query over at least one range of rows, and utilize the determined density to optimize the database query. By doing so, the density of various key values may be determined and compared, and a bit map may be generated over the range of rows of the key value that is denser, resulting in a reduction of resources to build and use the bit map. Moreover, from the bit map over the range of rows to be selected after using the determined density, dense regions may be identified that can be used to optimize block I/O's according to the number of rows to be selected based on the query.

Embodiments of the invention provide techniques for providing information describing locations to users of an immersive virtual environment. In one embodiment, patterns of locations visited by various users of the virtual environment may be stored in a searchable data structure(s). Further, characteristics of the location visits may be used to determine whether a given location visit was favorable for each user. Subsequently, locations visited by a current user may be matched to one of the stored patterns of locations. The matching pattern may then be used to provide favorability information describing other locations available to the current user. The favorability information may be presented to the user as graphical indications visible within the user's view of the virtual environment.

Methods, systems, and computer program products are provided for isolating database queries for performance processing. Embodiments typically include presenting to a user a prioritized list of potentially poorly performing queries; receiving from the user a selection of one or more potentially poorly performing queries; and executing performance processing of the selected queries.

A computer system and method of displaying hypertext documents indicate an update status for a particular hypertext document in association with the display of a hypertext link definition pointing to that document. In addition, one or more specific notification criteria are utilized to determine when a document has been updated. A notification criteria may be based upon a user selection of a selected portion of a document, such that changes to another portion of the document do not trigger an indication of an updated document. A notification criteria may also be based on a specific keyword search criteria selected by a user. A notification criteria may further be based on a relative change threshold for a document, such that changes to a document falling below the threshold are not indicated to a user. In addition, a notification criteria function may be based upon updates made by a particular author of a document, such that specific authors may either trigger or not trigger notification of an updated document.
摘要:
A method and system for use with a graphical user interface having a cursor, scroll bar, and slider provide consistent granularity in scrolling through various differently sized viewable objects displayed within a window of a graphical user interface. The method and system achieves the forgoing by (1) calculating a movement parameter dependent upon the length of a viewable object; and (2) scrolling through the viewable object at a rate dependent upon the calculated movement parameter, in response to user input.

A method, apparatus and program product are provided for servicing a production program. A mirror program is dynamically created using source code associated with the production program. The mirror program includes enhanced serviceability functionally relative to the production program that generates service information relevant to the production program. The mirror program executes while the production program remains in an active state such that the production program may be serviced using service information generated by the mirror program. The source code used to compile the production program is compared to a base line copy of the source code. Portions of the source code that differ from the base line copy of the source code are stored. The stored portions of the source code are associated with a unique identifier which is saved with the compiled production program.

The present invention is generally directed towards providing a method, system and article of manufacture for generating and utilizing debug history to improve the debugging process. By providing facilities to store and retrieve debug history records for given events, the present invention allows developers to debug code more efficiently by allowing them to leverage information stored in a debug history repository. Further, the added functionality, related to the debug history, is available via modules that work in conjunction with existing debugger applications and is provided to users via a variety of interfaces including graphic interfaces and plug-in components.
