"Then it was the old method of tracing armour-piercing firebombs that repelled the attacks of the big wasps twice. There was another very special sound from the position. At first we thought there was another big wasp coming, But after looking at it for half a day, I didn't find anything. After a little while, It is also the kind of special sound that is getting closer and closer. Only then did I recognize that it was not the "buzzing" sound of the big wasp, But a sound of "knowing, knowing, knowing, knowing, knowing, Taken out with 'creaking', It's like a lot of people grinding their teeth together, Then a piece of black came running in the direction of the position. This time the direction is straight ahead, At first those things were far away from us and we could not see them clearly with our naked eyes. It was an instructor with a telescope who looked through the telescope and saw that the thing was a lot of mice. And they are all very big, After the news spread throughout the position, I have all my comrades, All ready for battle, Knowing that this is like one of those big wasps, It is certainly not a good fault, Just thinking of starting to fight the newcomers when it comes closer, I didn't think they were about 100 meters away from the position. It stopped suddenly, At the beginning of digging holes collectively, I felt that they were digging holes faster than running on the flat ground. One by one, they almost disappeared from the ground in an instant. Soon, a large area of dark mice disappeared. Looking through binoculars, on the ground where they disappeared, there were many holes the thickness of sea bowls, which were almost denser than craters.A first-class pilot needs more than 1,000 hours of safe flight time.The Liskov Substitution Principle (LSP) is one of the basic principles of object-oriented design. The Richter substitution principle says that wherever a base class can appear, subclasses can certainly appear. LSP is the cornerstone of inheritance reuse. Only when derivative classes can replace base classes and the functions of software units are not affected can base classes be truly reused, and derivative classes can also add new behaviors to base classes. The Richter substitution principle is a supplement to the "open-close" principle. The key step to realize the "open-close" principle is abstraction. The inheritance relationship between the base class and the subclass is the concrete realization of abstraction, so the Richter substitution principle is the specification of the concrete steps to realize abstraction. --From BaiduTCP? SYN? Cookies? The specification format of does not involve interoperability issues, because they are only processed locally, and the specifications and procedures for generation and verification will vary slightly from implementation to implementation.The priority of the native module is second only to that of the file module cache. After parsing the file name, the require method first checks whether the module is in the list of native modules. Take the HTTP module as an example. Although there is a,,,, file in the directory, it will not be loaded from these files, but from the native module. ?1960
