A method, computer program product, and system for generating and embedding a watermark in digital video frame include a processor obtaining a request to generate a watermark and embed the watermark in a digital video frame captured by a first monitor. Based on obtaining the request, the processor fetches from one or more pre-defined regions of a memory resource, digital video data captured by at least two monitors, where a timestamp of the digital video data is equal to a timestamp of the digital video frame. The processor generates a watermark from the digital video data by calculating a binary result of the digital video data. The processor embeds the watermark (binary result) in the digital video frame.

A method and device for displaying an interface are provided. The method includes creating a fully-transparent sensing hot region displayed in a top layer in a screen; receiving a touch operation event, a starting touch position of the touch operation event being located in the sensing hot region; acquiring a lateral displacement of a sliding operation event when the touch operation event is the sliding operation event, the lateral displacement being a displacement in a width direction of the screen; detecting whether the lateral displacement is greater than a first threshold; and in response to determining that the lateral displacement is greater than the first threshold, switching from a first User Interface (UI) presently displayed in the screen into a second UI for display when the sliding operation event completes, wherein the second UI is a previous UI displayed immediately prior to the first UI.

A database cluster architecture based on dual port solid state disk (SSD) is provided. The database cluster includes a plurality of nodes and a plurality of dual port solid state disks (SSDs). Each dual port SSD of the plurality of dual port SSDs is connected to a unique pair of nodes and each node in the unique pair of nodes is connected to a unique pair of dual port SSDs. A first node of the plurality of nodes writes a transaction log to a first dual port SSD, a second node connected to the first dual port SSD acquires the transaction log from the first dual port SSD and operates a database process to recover data according to the transaction log when the first node crashes.

A method for recording a transaction log, and a database engine, and pertains to the field of database technologies. The method includes receiving an structured query language (SQL) request; modifying, according to the SQL request, a data page corresponding to the SQL request; generating a corresponding transaction log for the modifying; partitioning the transaction log to obtain a plurality of log segments; and writing the plurality of log segments into a plurality of log buffers, and writing the log segments in the plurality of log buffers into a log file in parallel. According to the present invention, not only lock granularities of the log buffers of the transaction log are reduced, but also a speed at which a log file is written into a magnetic disk is greatly increased, thereby improving performance of a database system and enhancing user experience.

Method for recording transaction log, and database engine

A method and a system for providing customizable, process-specific Just-In-Time debugging in operating system is provide in this invention. The method comprises the following steps: obtaining process-specific JIT debugging information, in response to the occurrence of an trap event in operating system; invoking the debugger corresponding to the process according to the obtained process-specific JIT debugging information. This method and system supports per-process JIT debugging configuration.

Providing customizable, process-specific just-in-time debugging in an operating system

A method and system for invoking Just-In-Time debugger is described, which can provide more efficient JIT debugging for complex code mixed applications. A method for invoking a Just-In-Time (JIT) debugger according to one embodiment includes checking a code type of a code address where a JIT debugging request is triggered from a process of a code-mixed application in response to the JIT debugging request from the process; acquiring corresponding JIT debugging information for different code types of the code-mixed application; and invoking a JIT debugger corresponding to the code type in response to the checked code type of the code address in the process and the acquired corresponding JIT debugging information.

A method and system for decompressing a compressed file is disclosed in this invention, the method comprising: reading a compressed data block from the compressed file; decompressing the compressed data block; outputting the decompressed data for storage into a decompressed file; deleting the compressed data block that was decompressed from the compressed file. The proposed method and system in this invention can reduce the unnecessary repeated data between compressed data and decompressed data. The storage space requirement will be reduced during decompression, and the existing compression/decompression algorithms need not be changed by using this invention. Thus, this invention is easy to be integrated into existing compression/decompression tools.
