By means of the embodiments of the present application, the problem of excessive difficulty in management or search caused by the excessive number of groups in a conversion list can be avoided, thereby improving the flexibility and convenience of group information interaction.
A data processing method and apparatus, and an intelligent network card and a server. On the basis of the method, before upgrading an auxiliary processor, a process corresponding to a dynamic area in the auxiliary processor can be preset in a memory of a load device connected to the auxiliary processor; during the specific upgrading of the auxiliary processor, a dynamic area to be upgraded in the auxiliary processor can first be determined to be a target dynamic area, target data which is input into the target dynamic area is determined, and a transmission path of the target data is then modified from originally pointing to the target dynamic area to pointing to a target process corresponding to the target dynamic area, such that during the upgrading process, the processing of the target data can be continued by means of calling the target process; and after the transmission path of the target data is modified in this manner, the target dynamic area is upgraded, such that the upgrading process of the auxiliary processor does not affect the data processing of the target data on the auxiliary processor, thereby ensuring the stability of the data processing on the auxiliary processor.
Provided are a content provision method and apparatus, a content display method and apparatus, and an electronic device and a storage medium. The content display method can comprise: acquiring target content, the target content matching a target behavior of a subject in a target video; and in response to the target behavior, displaying the target content in an associated manner in a display interface of the target video.
