A data deleting method and apparatus is provided in embodiments of this application. The method comprises: when a file system detects a delete request for a target file, examining a security property of the target file, wherein the security property of a file comprises secret classified property; if the security property of the target file is secret classified property, executing an overwrite operation on the target file and then executing a delete operation to delete the target file; wherein the overwrite operation comprises sending a write command to a SSD, the write command being a predefined write command which is expanded by adding an immediate scrubbing flag, to cause the SSD to invoke a backstage garbage collection program according to the predefined write command to immediately delete data on garbage blocks corresponding to logical block addresses of the target file.

User interface controls that facilitate the specification / modification of data hierarchies. In one set of embodiments, a first UI control component can be provided that comprises an ordered group of drop-down menus. Each drop-down menu in the ordered group can be populated with a selectable list of attributes from a data set and can be associated with a level in a data hierarchy. By selecting values using the various drop-down menus, a user can interactively specify a data hierarchy for the data set. The data set can then be visualized according to the specified hierarchy. In further embodiments, a second UI control component can be provided in addition to the first UI control component. The second UI control component can allow a user to interactively enable or disable certain drop-down menus in the ordered group, thereby acting as a “depth filter” for controlling the depth of the data hierarchy.

The invention relates to a surface temperature information fusion method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring multi-source surface temperature information of a target region, wherein the multi-source surface temperature information at least comprises first surface temperature information and second surface temperature information,the first surface temperature information is surface temperature data of each day of clear sky, and the spatial scale of the first surface temperature information is less than that of the second surface temperature information; and carrying out temporal-spatial fusion on the first surface temperature information and the second surface temperature information according to the spatial scale of thefirst surface temperature information, and calculating fused surface temperature information of the target region. By the adoption of the method, the accuracy of the fused surface temperature information can be improved.

The present application relates to a method and device for data processing, including: automatically executing data statistical tasks according to a preset timing program to obtain statistical results; performing serialization processing on the statistical results according to a preset page template to obtain results data; store the result data in the cache database; when receiving the view request, first inquire whether there is result data matching the view request in the cache database; if it exists, then respond the corresponding result data to the requesting end ; If not present, put the view request in the pending queue. The scheme of this application can extract valid data from massive data according to the requirements, and avoid junk data and invalid data in the data analysis process, thus greatly improving the efficiency of data analysis; using a unified page template to facilitate observation of data results; The server serializes data in different formats to facilitate interface docking during development and improve work efficiency.

The embodiment of the invention discloses a method and device for measuring image exposure parameters. The method includes: acquiring a detection image collected by an image acquisition device for a plurality of light-emitting units of the target device when the target device is working; The number of cycles corresponding to the interval and the light-emitting unit of the carry column determines the image exposure parameters of the image acquisition device; wherein, the light-emitting unit includes a unit column and a carry column, and the light-emitting unit of the unit column operates according to the set time interval when the target device is working Light up sequentially, and the light-emitting units in the carry column light up in turn according to the number of cycles that all the light-emitting units in the unit column complete the light-emitting cycle. By applying the solutions provided by the embodiments of the present invention, image exposure parameters can be determined more accurately.

The present application provides a product recommendation method, which includes the following steps: obtaining a product page of a related product that has a link relationship with the product page of the current product; calculating the first degree of association between the current product and the related product according to the link relationship; The information page related to the current commodity, determining the related commodity that has a co-occurrence relationship with the current commodity in the information page; calculating the second degree of association between the current commodity and the related commodity according to the co-occurrence relationship; according to the first The degree of association and the second degree of association determine a third degree of association between the current product and the related product; based on the third degree of association, a recommended product for the current product is determined. The present application also provides a commodity recommendation system implementing the foregoing method. The product recommendation method and system of the present application can reduce the amount of data processing during product recommendation and improve processing efficiency.

A collector (110) included in a data delivery control apparatus (100) collects data from a PLC (603, 604) and outputs the data to which collection time information indicating collection time is added. A validity determiner (140) determines whether the data is valid based on whether the collection time indicated by the collection time information added to the data is at or later than a starting time indicating a time at which a data sequence as a preset data processing sequence is started. A deliverer (130) delivers the data in accordance with a data sequence setting defining the data sequence in response to validity determination means determining that the data is valid.
