Abstract: The present disclosure provides a chassis assembly and a vehicle. The chassis component includes: a chassis provided with a plurality of mounting positions and configured to install a battery module; a quick-release device through which the battery module is installed on the mounting positions, wherein the quick-release device is controlled by a control system; and a voltage electrical connecting assembly electrically connected to the battery module, wherein the voltage electrical connecting assembly is controlled by the control system. The vehicle includes the chassis assembly.

Abstract: Aspects of the invention include systems and methods configured to prevent masquerading service attacks. A non-limiting example computer-implemented method includes sending, from a first server in a cloud environment, a communication request comprising an application programming interface (API) key and a first server identifier to an identity and access management (IAM) server of the cloud environment. The API key can be uniquely assigned by the IAM server to a first component of the first server. The first server receives a credential that includes a token for the first component and sends the credential to a second server. The second server sends the credential, a second server identifier, and an identifier for a second component of the second server to the IAM server. The second server receives an acknowledgment from the IAM server and sends the acknowledgment to the first server.

Abstract: In an approach to improve asynchronous replication in database clusters embodiments retain committed transactions during database cluster replication. Embodiments build and run asynchronous replication logic using database nodes running as one or more standalone nodes, wherein the asynchronous replication logic is responsible for data replication from a primary database node to one or more secondary database nodes. Embodiments register a replication reader to a sender node to replicate journal logs and replay the journal logs on the one or more secondary database nodes. Further, embodiments monitor replication lag metrics from the sender node and notify a replication source and a replication target of a generated replication plan, wherein the cluster controller instructs the replication source and the replication target to be ready to initiate the replication plan. Additionally, embodiments adjust a replication plan to allow the asynchronous replication logic to catch up and complete uncommitted transactions.

Abstract: The method includes: in a projection scenario, a first device displays, in a first display area of a display, a first user interface of a first application running on the first device, and displays, in a second display area of the display, a second user interface that is being displayed by a second device. The second user interface includes one or more file objects. A user may drag a first file object on the second user interface to the first user interface to release, so that the second device transfers the first file object to the first device. Then, the first device stores the first file object, and provides the first file object for the first application for processing. In embodiments, application data of one device can be directly shared to an application of another device without switching a user interface for a plurality of times.
