Abstract: A data management method, apparatus, device, a computer-readable storage medium, and system are provided. The method is applied to a first network device, the first network device determines target invalid data existing in a second network device, the first network device obtains a first RPC, and the first RPC carries information about target invalid data that needs to be deleted. Then, the first network device sends the first RPC to the second network device, where the first RPC is used to indicate the second network device to delete the target invalid data. In this application, residual data is automatically identified, and the residual data is cleared, to automatically delete the residual data in batches, thereby saving device resources and improving an operation and maintenance management effect.

Abstract: A data processing method, apparatus, and system are disclosed. The method includes: A management device generates a request message, where the request message includes a quantity of list entries, identification information, and an offset. The management device sends the request message to a network device, where the request message is used to request, from the network device, a list entry that is in a list identified by the identification information, that uses the offset as a start location, and that is indicated by the quantity of list entries, and a total quantity of list entries included in the list is greater than the quantity of list entries. The management device receives a response message corresponding to the request message from the network device, where the response message includes a list entry requested by the request message.

Abstract: A personal content stream comprising a plurality of videos is generated for a user. The user selects topics used in the generation of a personal content stream. The plurality of user selected topics is expanded to include topics related to one or more of the user selected topics. Each of the topics in the expanded plurality of topics includes a topic weight. Videos are selected that are related to one or more of the expanded plurality of topics to generate a plurality of stream videos. Additional videos are selected and added to the plurality of stream videos as the user watches videos. The topic weights are adjusted during video playback based on feedback from the user.

Abstract: A system and method for developing a user's profile based on the user's interaction with content items. A module on the client rendering the content items or the service including the content items tracks the user's interactions with the content items and transmits the tracked data to a user analysis module. The user analysis module determines the topics associated with the interacted upon content items. The user analysis module then selects the topics for the user's profiles based on the received tracked data and the associated topics. The selected topics are mapped to topic clusters and the topic clusters are stored in association with the user profile. Recommendations for a user are made based on the topic clusters associated with the user'profile.

Abstract: The present disclosure provides a method and a system for configuring telecom device, and telecom device. The method includes: receiving configuration data and a first confirmed-commit operation command that are sent by a user, to perform a confirmed-commit operation; cancelling the confirmed-commit operation upon receiving a cancelling command sent by the user; storing the configuration data in a candidate configuration database; and receiving modified configuration data and a second confirmed-commit operation command to perform a new confirmed-commit, where the modified configuration data and the second confirmed-commit operation command are obtained after the user modifies the candidate configuration database. In the present disclosure, by cancelling the confirmed-commit operation and reserving the configuration candidate database, a mechanism to intervene the confirmed-commit operation initiatively is provided to the user to improve configuration efficiency, and relieve data transmission pressure.

Abstract: A personal content stream comprising a plurality of videos is generated for a user. The user selects topics used in the generation of a personal content stream. The plurality of user selected topics is expanded to include topics related to one or more of the user selected topics. Each of the topics in the expanded plurality of topics includes a topic weight. Videos are selected that are related to one or more of the expanded plurality of topics to generate a plurality of stream videos. Additional videos are selected and added to the plurality of stream videos as the user watches videos. The topic weights are adjusted during video playback based on feedback from the user.

Abstract: A hinge for glasses includes a hinge part securely attached to a central part, a housing firmly connected to a glasses leg, and a spring-core device received in the housing. The spring-core device includes a core shaft with a securing means, a slide block and a coiled spring disposed around the core shaft, and a single-tooth core body rotatably connected to the hinge part. The single-tooth core body is firmly connected to the core shaft, and the slide block is positioned in the housing. The coiled spring is respectively resisted against the securing means and the slide block. When the glasses leg rotates outwards to a slight angle at a wearing position, the single-tooth core body is pulled outwards to thereby cause the slide block to position in the housing and cause the coiled spring to be compressed.
