For example, I want to do a statistic on the homepage, Number of articles, number of users, the latest users, such as statistics, if you want to count from MySQL every time, too much resources. How does that make up a small amount of resources, and

If the Web server is directly connected to DB, the hacker can find the DB username and password in the code after the Web server is compromised, potentially causing the risk of being dragged. And for DB, the number of connections is capped, and when

This example has two features:1. The effect of the three columns in the middle can be any single-column background color.2. The whole screen is the shortest 770px and the shortest width is 1024px. That is to say, if the window is smaller than 770xp,

　　InterruptInterruption is necessary for the design of multi-channel program. Interrupts are a reaction that the CPU makes to an event that occurs on the system. The event that caused the interruption is called the interrupt source. The request that

In pattern recognition, we take into account the problem of distance distance, which is the distance between a sample and another sample in space. The classification is judged by the size of the distance. So, there is the same kind of problem: we
