Abstract: Embodiments of the present invention disclose a security processing method and system in a network handover process. The method includes: generating, by a network switching node, a target key after receiving a handover request; sending, by the network switching node, security information including the target key to a target network node, and receiving a handover response message sent by the target network node; and sending, by the network switching node, a handover command to a mobile terminal, so that the mobile terminal accesses a target network. By adopting the present invention, security processing in handover of a mobile terminal from a 3G network to an HSPA network or an LTE network may be completed in a case that the network switching node currently used in the network is not changed.

Abstract: Techniques for error report processing are described herein. Error reports, received by a developer due to program crashes, may be organized into a plurality of “buckets.” The buckets may be based in part on a name and a version of the application associated with a crash. Additionally, a call stack of the computer on which the crash occurred may be associated with each error report. The error reports may be “re-bucketed” into meta-buckets to provide additional information to programmers working to resolve software errors. The re-bucketing may be based in part on measuring similarity of call stacks of a plurality of error reports. The similarity of two call stacks—a measure of likelihood that two error reports were caused by a same error—may be based in part on functions in common, a distance of those functions from the crash point, and an offset distance between the common functions.

Abstract: Techniques for mining API method usage patterns from source code are described. These techniques include parsing the source code to generate API method call sequences that include an API method. These call sequences are clustered to obtain clusters. Based on the clusters, frequent closed sequences are determined and then clustered to obtain an API usage pattern. In addition, optimal clustering parameters may also be determined. In some instances, a graphical representation is generated based on the API usage pattern in response to a query associated with the API method.

Abstract: An enhanced navigation system detects a predetermined input gesture from a user and presents one or more gesture panels at pre-designated positions on a display of a touch-surface device or positions determined based on where a user is likely to hold the device. The user may navigate content of the application currently presented in the display by providing one or more input gestures within the one or more gesture panels, thus saving the user from moving his/her hands around the display of the touch-surface device while holding the touch-surface device. The enhanced navigation system further enables synchronize one or more gesture definitions with a cloud computing system and/or one or more other devices.

Abstract: An input polynomial, in symbolic form, is received, classified, pre-processed, and factored. The input polynomial is classified as a constant, a univariate polynomial, or a multivariate polynomial. Various pre-processing is performed depending on the classification. After the input polynomial is pre-processed, the remaining polynomial is factored using a polynomial factoring algorithm. By pre-processing the input polynomial, the complexity of the polynomial to be factored is reduced, which reduces the computational expense of the polynomial factoring algorithm.

Abstract: A data exploration user interface includes a selection area with selectable representations of queryable fields of a data source and a visualization area where query results are displayed as data visualizations. Queries are generated by dragging fields from the selectable area to the visualization area of the user interface. A tree structure of data visualizations may be created by dragging data points out of a displayed visualization and applying additional fields to create a new query and resulting visualization. The tree structure is graphically represented with path indicators that provide historical context for each new data visualization within the visualization are of the user interface.
