A method and system for identifying garbage data, an electronic device, and a storage medium. The method includes: uploading an object to a distributed object storage system (S101); acquiring a head object identifier in an index storage pool of the distributed object storage system (S102); querying a data storage pool for a target data group corresponding to the head object identifier (S103); marking a tail object corresponding to a tail object identifier in the target data group as a target tail object (S104); and marking tail objects in the data storage pool other than the target tail object as garbage data (S105). The method can identify garbage data in a distributed object storage system.

In accordance with some embodiments, a method includes detecting a management input indicative of a request to manage data stored at the direction of the device at a storage location with a limited available storage capacity, and in response, displaying a data storage management user interface that includes a plurality of data storage management affordances. The method further includes, detecting selection of a particular data storage management affordance of the plurality of data storage management affordances; and, in response to detecting selection of the particular data storage management affordance, in accordance with a determination that the particular data storage management affordance is the first data storage management affordance, initiating a process for performing the first data storage management operation and, in accordance with a determination that the particular data storage management affordance is the second data storage management affordance, initiating a process for performing the second data storage management operation.

A biological information measuring apparatus includes a sensor unit, a processing unit that detects biological information on the basis of sensor information received from the sensor unit, and a communication unit that transmits the biological information to a connection target device at a transmission speed corresponding to a scheduled transmission data amount of the biological information.

A page query method and a data processing node in an OLTP cluster database are disclosed. The OLTP cluster database includes a central node and at least one data processing node, the central node manages a PLock in a passive PLock releasing processing manner, and the method includes: searching a shared memory for a page digest of a first page when the data processing node needs to query the first page during a data query and the first page is not in storage space of a database buffer; and if it is determined target data of the data query cannot be on the first page, skipping performing a query operation on it; or if it is determined the target data may be on the first page, loading it into the storage space of the database buffer, and traversing the first page to perform the data query.

A method for storing data in a storage system. In one embodiment, implementation of a method for storing data in compliance with a compression handling instruction includes: at a storage controller, receiving an object for storage within a data storage, wherein the object is in an original state; determining whether a compression handling instruction is received in association with the object; and executing the compression handling instruction when storing the object.

Systems and methods for managing content to improve battery life of client devices. A data processing system receives requests for content items from client devices. The data processing system selects the content items from a set of content items and transmits the content items to the respective client devices. The client devices acquire battery status information related to the displaying or rendering of their respective content item. The data processing system receives the battery status information from the client devices and determines a power consumption value associated with the content items. Based on the power consumption value being greater than a threshold power consumption value, the data processing system modifies a policy for selecting the content items from the set of content items.

A cleanup method and device for a terminal resource and a terminal. The method comprises: receiving a cleanup instruction, and acquiring a resource saved on a terminal according to the cleanup instruction (S101); processing the resource, and saving the processed resource, wherein a storage space occupied by the processed resource is less than a storage space occupied by the resource (S102); and querying whether a resource is saved on a server, if the resource is saved on the server, then displaying deletion prompt information, and deleting the resource according to an operation executed by a user (S103). By means of the cleanup method and device and the terminal, the storage space of the terminal occupied by a resource can be greatly reduced, and at the same time, convenience can be provided for a user to redisplay the resource since it is guaranteed that the corresponding resource is saved on a server before the resource is deleted.

A data amount reduction unit of a data processing system of a construction machine is configured to reduce, based on a preset first reduction rule, a data amount of first image data that is a portion corresponding to a preset first specification work among time-series image data stored in a data storage unit, and reduce, based on a preset second reduction rule, a data amount of second image data that is a portion corresponding to a preset second specification work among the time-series image data stored in the data storage unit.

A method of data storage includes associating delta colour compression DCC metadata with one or more tiles of graphics data, selecting one or more such tiles that are uniform in colour and hence can be accurately represented by the DCC metadata for that tile, and replacing some or all of the graphics data in one or more selected tiles with different data.
