DDOS attacks mainly occur in the network layer. Its most obvious characteristic is to send a large number of attack packets, consume network bandwidth resources and affect normal users' access. At present, the detection and defense technology for DDOS attacks in the network layer is quite mature, and at the same time, some new attack methods-DDOS attacks in the application layer have emerged. Different from network layer DDOS attacks, application layer DDOS attacks mostly imitate the access behavior of legitimate users and will not generate a large number of attack data packets during data transmission, but they will consume server resources through a large number of database queries and other operations, which is more difficult to detect. According to the different attack modes, DDOS attacks include reflection amplification attacks in addition to ordinary flooding attacks. This type of attack often uses a legitimate server as a reflector, which sends a large number of data packets to the target, thus causing greater harm. At present, DDOS attacks against DNS servers are also common. Attackers often send fake domain names to DNS servers, consuming DNS server resources. At the same time, due to the recursive query mechanism in DNS servers, DDOS attacks against DNS servers have a large impact range.

He Yihe especially likes a statement made by Tang Wang, a Mexican witch doctor, "Everyone has a god of death, right behind his left shoulder. When I don't realize something, look back and ask, 'What do you think, man'. Remind me of the fact that I will die all the time so as to lead a meaningful life."

In the previous example of electric lights, a state mode program was completed. First, the Light class is defined, which is also called Context here. Then in Light's constructor, to create instance objects for each state class, Context will hold references to these state objects in order to delegate the request to the state objects. The user's request, that is, the action of clicking button, is also implemented in Context, with the following code:

当年轰动一时的“透明人”又回来了，克利斯汀·史莱特主演，情节发展不温不火，故事节奏进退有补，重点场面的电脑特效并不逊色第一集多少，结尾的一场雨中决战乃片高潮，两个透明人之间的战斗极为精彩，关于这类的电影实属不多，本片正当值得欣赏。
