Information Theory: I forget which publishing house it was. It is a very thin book and it is very good. There is a good talk about the measurement of information, the understanding of entropy and the Markov process (there is no such thing in the company now, I'll go back and find it and make it up). Mastering this knowledge, it is good for you to understand the cross entropy and relative entropy, which look similar but easy to confuse. At least you know why many machine learning algorithms like to use cross entropy as cost function ~该剧讲述了韩国财阀继承女尹世利（孙艺珍 饰）因滑翔伞事故被迫降到北韩，爱上默默守护她的北韩特级军官（玄彬 饰）的故事。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.想了很久，他才问道：夷人，难道没有皇帝么？夷人的皇帝难道与我们的皇帝不同么？夷人有皇帝，夷人的皇帝也没有太大的不同。How to acquire professional skills, no one can deny the meaning of practice makes perfect. Lazy by nature, we are always looking for excuses and trying to avoid practice. One day, Gladwell, author of the best-selling book "Alien," told you: "The reason why genius in people's eyes is outstanding is not that it is superhuman, but that it has made continuous efforts. As long as it takes 10,000 hours of training, anyone can change from ordinary to extraordinary."沉声道：何风，本将军还没死呢。
