Abstract: A system and method for activating bookmark files on a pervasive computing device is provided. When the pervasive computing device receives geographic coordinates from a global positioning system (GPS), it selects appropriate bookmarks for the user's location. The pervasive computing device compares geographic coordinate data received from the GPS with geographic matching data stored on the pervasive computing device. In addition, actions are taken to perform commands when the user is within the proximity of a location. Scheduling means are provided so that actions are performed during appropriate times. The pervasive computing device further connects to a computer network, such as the Internet, to access data files and to perform commands on external computing devices. If the commands are executed successfully, a success action is performed on the pervasive computing device. On the other hand, if errors were encountered a failure action is performed notifying the user of the error.

Abstract: An apparatus and method for cataloging symbolic data for use in performance analysis of computer programs is provided. The apparatus and method stores symbolic data for loaded modules during or shortly after a performance trace and utilizes the stored symbolic data when performing a performance analysis at a later time. A merged symbol file is generated for a computer program, or application, under trace. The merged symbol file contains information useful in performing symbolic resolution of address information in trace files for each instance of a module. During post processing of the trace information generated by a performance trace of a computer program, symbolic information stored in the merged symbol file is compared to the trace information stored in the trace file. The correct symbolic information in the merged symbol file for loaded modules is identified based on a number of validating criteria.

Abstract: A method and implementing computer system is provided in which the actual frequency of system timing signals is determinable. In one example, an output from a programmable interrupt timer is selectively sampled and a determination is made of the actual frequency of the interrupt signal. A user may indicate the number of samples upon which the frequency calculation will be based and the determined actual frequency in real time is saved for reference as needed by system requirements and other applications. In one embodiment, the number of samples and the calculated actual interrupt timer frequency, as well as other related information such as time and date of the latest calculation, is presented on a user display device.
