The principle of opening and closing means opening to expansion and closing to modification. When the program needs to be expanded, the original code cannot be modified, but the original code should be expanded to achieve a hot plug effect. Therefore, a summary of one sentence is: in order to make the program scalable, easy to maintain and upgrade. To achieve this effect, we need to use interfaces and abstract classes, etc. We will mention this point in the later specific design.
ゴールデン街、荒木町、早稲田、新大久保、新宿二丁目、三丁目―。これらの街を管轄区域とした新宿東署では、日々多くの事件が起こり、刑事が認知していても動けない“手付かず案件”となっている事件が多くある。そんな新宿東署に、一人の車椅子の刑事が配属された。彼の名は、鬼塚一路（北大路欣也）。定年間際の最後の事件で、犯人に刺されて両足の機能を失い車椅子生活となった彼は、１年後、新宿東署刑事課の司法係長に再任用された。鬼塚は、新米時代と定年間際の二度、この新宿東署に配属されている。これにより彼は「昭和」と「平成」ふたつの時代を通して新宿の街の詳細な記憶を持ち、事件を推理する際、「記憶の街」として脳内に描き出すことができる。“手付かず案件”により困っている人がいることを知った鬼塚は気になる事件を調べるようになる・・・そんな中、刑事志望の遠山咲（上白石萌音）とキャリアの刑事官・神啓太郎（風間俊介）が配属される。二人が車椅子の鬼塚の足となり、手付かず案件の捜査が始まる！

The general code is like this, and I feel that the code using the intermediary mode is similar, so I won't introduce it much here. The code in the book has advantages, but I don't feel that there is much difference, so I no longer use the intermediary mode to write code here. State mode is an unusually excellent mode, which may be the best way to solve some requirement scenarios. Although the state mode is not a simple to clear mode (it often brings about an increase in the amount of code), once you understand the essence of the state mode, you will certainly thank it for its incomparable benefits in the future. The key to the state mode is to distinguish the internal state of things. Changes in the internal state of things often bring about changes in the behavior of things. This article describes the state mode in detail
If an attacker sends SYN packets quickly with their own undisguised IP address, this is a so-called direct attack. This attack is very easy to implement because it does not involve spoofing or modifying packets below the user layer of the attacker's operating system. For example, he can simply send many TCP connection requests to implement this attack. However, for this attack to work, the attacker must also prevent his system from responding to SYN-ACK packets because of any ACK, RST, or ICMP (Internet? Control? Message? Protocol) will cause the server to skip the SYN-RECEIVED state (go to the next state) and remove the TCB (because the connection has been successfully established or recycled). Attackers can do this by setting firewall rules, causing the firewall to block all packets (except SYN) to reach the server, or causing the firewall to block all incoming packets so that SYN-ACK packets are discarded before reaching the local TCP handler.
"'How good is the effect very good'?" I asked.

This summer vacation, I took part in the "Social Practice Activities for College Students to Go to the Countryside in Summer" organized by the School of Urban Management of Hunan City University. In order to let students better master professional knowledge, Carry forward patriotic enthusiasm, serve the society and the people attentively, let students have all-round contact, understand the situation of poor areas in society and personality, and through investigation, find out the actual problems existing in the area, analyze and make solutions, and experience and comprehend from them to enhance the sense of mission of college students. In order to cultivate good social adaptation potential and strive to train oneself to become a contemporary college student who is beneficial to the society and the people, Secretary Liu Hui, Secretary of the General Party Branch of the Institute of Urban Management, was arranged to be our leading teacher. Under the form of building a new socialist countryside in the whole country, the theme of our activity is "serving the new countryside and building a new home."

The main difference between the proxy mode and the appearance mode is that the proxy object cannot directly access the object, but can only be accessed by the proxy object, while the appearance object provides a simplified access call interface for each subsystem, while the adapter mode does not need to fabricate a proxy, so as to reuse the original interface. The appearance mode defines a new interface, while the adapter reuses an existing interface.
