A method, system, and computer program product for dependency-based software upgrading. The method may include determining respective dependency degrees between a plurality of software products based on property information related to a plurality of upgraded versions of the plurality of software products, a target software product depending on the plurality of software products. The method may also include dividing the plurality of software products into a plurality of groups of software products based on the respective dependency degrees. The method may also include determining a plurality of test scores associated with the plurality of groups, each test score indicating a performance enhancement degree of the target software product achieved by installing upgraded versions of at least one software product comprised in one of the plurality of groups. The method may also include determining a target upgrade solution for the target software product based on the plurality of test scores.

Dependency-based software upgrading

Aspects include determining a coding intention and a dimension of interest to a user. A plurality of relevant projects that each include a logical code block that meets the coding intention are located. The locating includes searching a plurality of code repositories based at least in part on the coding intention. A score is assigned to each of the plurality of logical code blocks based at least in part on properties associated with the logical code blocks and on the dimension of interest to the user. A logical code block with the highest score is promoted to the user.

Dynamic code snippet promotion

Implementations of the present disclosure relate to security testing based on user request. According to the method, a first request for a target application is received from a first user. A first malicious request is generated by modifying the first request, wherein the first malicious is associated with a malicious action on the target application. The first malicious request is sent to an offline instance of the target application. A first security level of the target application against the malicious action is determined based on a first response generated by the offline instance in response to the first malicious request. In other implementations, a system and a computer program product for process tracking are disclosed.

Security testing based on user request

The present invention provides a computer implemented method, system, and computer program product for monitoring a ticket, the method including receiving credentials by a processing unit from a device via manual presentation of the device to a manual sensor logically coupled to the processing unit, generating a ticket identifier (ID) based on the credentials, transmitting the ticket ID from the processing unit to the device, establishing a wireless connection between the device and the processing unit, checking the wireless connection before each occurrence of an event, checking the wireless connection after each occurrence of the event, and updating a status of a ticket in light of the checking. In an exemplary embodiment, a ticket system includes a processing unit, a manual sensor, a wireless sensor, and a device, where the processing unit transmits the ticket ID, and where the processing unit verifies continued connection at key events.

Monitoring tickets on transportation systems

The invention provides a method and apparatus for determining the direction of a signal such as for example a received radio signal in a cellular mobile communication system. At lest two antenna arrays ( ) are connected to associated processors ( ) for extracting the desired signal and two independent direction of arrival estimates are determined in associated direction estimators ( ). A similarity testing unit ( ) determines the direction of arrival and the accuracy of this estimate from the difference between the two estimates. A feature of the invention is controlling the beam form of a downlink signal in response to the direction estimate and the determined accuracy.
