Abstract: A drivable exercise machine may include an electric vehicle with human power input provided by a high output, variable-resistance pedal-driven generator. The vehicle may include a computing device with a user interface that mimics an electric exercise bicycle. Using one or more program modes, a user may activate pre-set, custom and dynamic terrain-based exercise program profiles while commuting.

Abstract: Initial items can be partitioned into a plurality of partitions. The partitions can be stored in a partitioned list in computer storage. An index to the partitions can be generated. One or more initial items can be invalidated, and additional items can be appended to the partitioned list in a storage space previously occupied by the invalidated initial items. The index can be updated to omit references to the invalidated items, and to include references to the additional items. Also, a slice of an application call tree can be generated from a partition loaded into memory from a log. A representation of the slice can be displayed on a computer display, even before the entire application call tree is generated from the log.

Abstract: A system and method for facilitating analysis and modification of a computer program. A directed graph is generated from an intermediate language representation of a computer program function, with a node representing each instruction. Meta-edges or meta-nodes are inserted into the directed graph to facilitate location of instruction nodes. One type of meta-edge is a back edge that identifies branch instruction nodes. Some meta-nodes may identify instructions of a specific type. Some meta-nodes may identify exception blocks and corresponding handlers. Analysis of a program function may include insertion of new instructions prior to execution of the function.

Abstract: A system and method for generating a computer program call graph. A profiler may insert probes into a debuggee computer program, the probes generating call trace events. Checkpoints may be performed during execution of the debuggee program, so that a snapshot of the call stack is performed. Call trace events and checkpoint snapshots are logged and serialized. Logged call trace events and checkpoints may be retrieved and used in combination to generate a call graph and a shadow stack. Mechanisms facilitate combining the different sources of debuggee program information and determining whether the call graph and shadow stack are determinate or indeterminate at any time. The mechanisms may provide for improved accuracy of generated call graphs.

Abstract: The present disclosure is directed to an electric vehicle with human power input provided by a high output pedal-driven generator. The vehicle includes a computing device with a user interface that mimics an electric exercise bicycle, with both pre-set and custom exercise program profiles.

Abstract: Various technologies and techniques are disclosed for providing an execution-centric view of source code. Source code is reconstructed in an execution-centric format from a prior execution of an application. Trace data is used to determine which code addresses were executed during a prior execution of an application. Addresses in the trace data are mapped back to source code to reconstruct the source code in the execution order. The source code is then displayed in the execution-centric format. Other events that occurred at different points in time can be overlaid in the display of the execution-centric source code.

Abstract: Systems and methods for automated monitoring and management of distributed applications, client/server databases, networks and systems across heterogeneous environments. Distributed, automated intelligent monitoring agents use embedded sensing technology which is knowledgeable of application protocols, to monitor continuously the network environment in real time. To this end, the monitoring agent can be located on each client and server in the network. The monitoring agent can couple to the communications stack for monitoring the data that is being passed between the client and the network, of a server in the network. The data can be collected and employed for trouble shooting trend analysis, resource planning, security auditing, and accounting as well as other applications. Also included is a controller for remotely coordinating the data gathering process from the various clients and servers.

Abstract: A quick release mechanism is provided having a drawbar with a camming lock positioned at one end and an end cap positioned at the opposing end. The camming lock includes an axle having a plurality of primary locking slots formed therein. The camming lock also includes a cam having a receiving chamber formed therein and a tongue radially projecting therefrom. A plurality of primary locking slots extend from the tongue to the receiving chamber. The receiving chamber is configured to receive the axle so that the cam can freely rotate relative to the axle and the primary locking slots can be aligned with the secondary locking slots. Selectively positioned within secondary locking slots are a series of pins and springs. When secondary locking slots and the primary locking slots are aligned, select pins extend therebetween, thereby preventing annular rotation of the cam relative to the axle.
