  • Publication number: 20250047919
    Abstract: A method for facilitating streamer interaction with a viewer includes extracting a history topic based on an activity record of the viewer; calculating a score of each of the history topics based on at least one parameter; and generating a topic suggestion based on the history topic and the score which is corresponding to the history topic, and providing the topic suggestion to the streamer. The method is suitable for providing a topic suggestion (or interact topic suggestion) with respect to the viewer to the streamer via a live-streaming platform executed by a computing device. Thereby, the method can be used for facilitating streamer interaction with viewers and provides an appropriate topic suggestion. In addition, a computing device and a computer-readable storage medium which are capable of implementing the method are also provided.

  • Publication number: 20250040075
    Abstract: A computing device include a chassis, a mounting ear, a lever, and a locking unit. The chassis holds one or more electronic devices and is insertable into a rack, such as a server rack. The mounting ear is coupled to the chassis. The lever is rotatably coupled to the mounting ear and is rotatable between a first position and a second position. In the first position, the lever engages the rack to prevent the chassis from being removed. In the second position, the lever disengages the rack and allows the chassis to be removed. The locking unit is coupled to the mounting ear and transitions between locked and unlocked states. In the locked state, the locking unit secures the lever in the first position. In the unlocked state, the lever is movable from the first position to the second position.
