摘要： Embodiments of the present invention relate to password authentication. According to an embodiment of the present invention, a password associated with a user identification is received from a user device. The password is authenticated based on a preset relationship between a seed password and a graphical password associated with the user identification. The seed password consists of a string of characters. The graphical password is a directed path traversing all keys of a keypad in an order. Each of the keys represents one of the characters and is associated with an order number according to the order of the keys being traversed. The preset relationship is that the password consists of respective order numbers associated with respective keys representing corresponding characters of the seed password.

摘要： Techniques include executing a software program having a function call to a shared library and reloading the shared library without stopping execution of the software program. A global offset table (GOT) is updated responsive to resolving a link address associated with the function call. An entry in GOT included a link address field, an index field, and a resolved field, the updating including updating the index field with an affirmative value and marking the resolved field with an affirmative flag for the entry in the GOT. Responsive to reloading the shared library, the entry in the GOT is found having the affirmative value in the index field and the affirmative flag in the resolved field. An address value in the link address field is returned for the entry having the affirmative value in the index field, responsive to a subsequent execution of the function call to the shared library.

摘要： Embodiments of the present disclosure relate to a method, system, and computer program product for comparison of database data. According to the method, a first tree structure corresponding to first data segments of first database data and a second tree structure corresponding to second data segments of second database data are at least partially obtained. Each node of the first or second tree structure indicating a characteristic value of at least one of the first or second data segments, and nodes of the first or second tree structure are divided into a first or second plurality of branches from a first or second root node based on update frequencies of the first or second data segments. A difference between the first data segments and the second data segments is determined by at least comparing characteristic values indicated by nodes in the obtained parts of the first and second tree structures.

摘要： Mechanisms are provided for scheduling a workload in a cloud computing system. A cloud affinity factor (CAF) computer model is trained, via a machine learning process based on a training dataset comprising static characteristics of a workload binary for a workload, and dynamic characteristics corresponding to historical performance data for the workload, such that the trained CAF computer model predicts a performance classification for a given workload binary. The trained CAF computer model processes a new workload to generate a performance classification for the new workload. Cloud affinity factor(s) are generated based on the performance classification for the new workload. Node affinity and dispatch rule(s) are applied to the cloud affinity factor(s) to select one or more nodes of the cloud computing system to which to dispatch the workload. The workload is then scheduled on the selected one or more nodes.
