Abstract: A method for tracking in Office file conversion and modification processes, including the following steps: S1: generating a piece of customized data containing a unique ID; S2: when an Office file is being generated or is generated, using a custom XML mechanism for Office files to save the customized data in the XML format into the Office file; S3: keeping the unique ID unchanged when the Office file is modified; S4: when the Office file is converted into a target file of a target format, if the target format supports the saving of the customized data, then transferring the customized data into the target file, thus allowing a user to manage the target file on the basis of the customized data; S5: when the Office file acquired in step S2 is updated and a new Office file is generated again, keeping the unique ID unchanged in the new Office file.

Abstract: Technologies for performing non-intrusive fine-grained power monitoring of a datacenter are provided. Hardware component state information for servers in the datacenter is collected, along with aggregate power consumption measurements for the datacenter. The servers are grouped into multiple virtual homogenous server clusters (VHCs) based on characteristics of the servers. A power model is constructed comprising multiple power mapping functions associated with the multiple VHCs. Component state information of a particular server can then be analyzed, along with a corresponding aggregate power consumption measurement, using the constructed power model to determine an approximate power consumption of the particular server. The approximate power consumption of the server can then be displayed and/or provided to one or more power management applications.

Abstract: In a trusted document updating method, a globally-unique document identifier and an access address of a corresponding cloud server are set in each managed document. Characteristic data of a version that is not modified and characteristic data of a new version are submitted to a cloud server. Version characteristic update information is recorded. The cloud server and a tree-shaped data structure are accessed. The cloud server removes a leaf node a corresponding author of which is not a neighbor in the tree-shaped data structure. All leaf nodes in a subtree using current document eigenvalue as a root are added into a list of “a latest edition of a current version.” Data of a corresponding version is downloaded from the cloud server according to a version selected by the user.
