Shorten the waiting time before closing the service As we mentioned above, in the Shutdown Process of Windows Vista, the system first sends a shutdown warning to the loaded services, and then waits for the Shutdown signal given after these services are automatically closed, if you do not receive a close signal after the specified wait

Preface: wrote a script before, want in the IP site inquires over more than 1000 domain name the record information, but some domain name is not the record, therefore cannot find the element, although I already set the unusual judgment, but the default waiting 30 seconds time let me unbearable. Then after a variety of Baidu found a solution. Digression: A colleague uses Nodejs to solve more than 1000 data in 2 minutes by means of an asynchronous cont

application. For example, most applications require at least one user authentication process. Therefore, the user name must be saved in the database during system implementation. Because this user name involves user authentication, the user name must be unique. In this case, the uniqueness constraint is required. In relational databases, you only need to set the user name to unique during table design. In NoSQL, code must be used for uniqueness. It was easy to implement, but now it is incredibl

If you are more careful, you will surely find that when we turn off the w764-bit flagship download, the Win7 flagship will have a hint to wait for the system to shut down, and then we need to wait a while before the computer shuts down. Although many users have been accustomed to the system such defaults, but for some users, but the urgent hope that the Win7 flagship version of the shutdown

In the Linux driver, you can use To wake up the blocking process. Wait Queue has long appeared in the Linux kernel as a basic function unit. It uses the basic data structure of the queue bit and closely integrates with the process scheduling mechanism to implement asynchronous event notification machines in the kernel. . Wait
