When a client accesses a server's web service, The client sends a message to the network card, The tcp/ip stack is part of the kernel, Therefore, the client information is transferred to the web service in user space through the kernel's TCP protocol, At this time, the destination destination of the client message is on the socket (IP: Port) that the web service is listening for. When a web service needs to respond to a client request, The destination destination of the response message sent by the web service is the client, At this time, The IP and port that the web service listens on becomes the origin instead, As we said, Netfilter is the real firewall, It is part of the kernel, Therefore, if we want the firewall to achieve the goal of "fire prevention", You need to set up checkpoints in the kernel. All incoming and outgoing messages have to pass through these checkpoints. After checking, those that meet the release conditions can be released, while those that meet the blocking conditions need to be blocked. As a result, input checkpoints and output checkpoints appear. These checkpoints are not called "checkpoints" but "chains" in iptables.

上世纪40年代初，疯狂的日本帝国主义份子在做最后垂死“进攻”一场以“血色樱花”为代号的巨大军事行动，由此在风雨飘摇的大上海密秘展开。抗战以来，日本帝国大学毕业的中田一郎（刘钧饰）一直参于731细菌部队生化武器的研究，作为共产党的一份子一直潜伏在敌人内部，借这次“血色樱花”行动，跟随山本桢昭大将来到上海，而一直潜伏在我党内部的曼丽大佐（涂黎曼饰）也密秘的行动着
B) Design principles. Many people have listed seven principles, such as single duty principle, opening and closing principle, Richter substitution principle, dependence inversion principle, interface isolation principle, composite reuse principle and Dimit principle. LSP, I elevated it to one of the three cornerstones of the object-oriented paradigm; Single responsibility and interface isolation are mainly used as the principle of responsibility division in object-oriented analysis/OOA, which you can not pay much attention to at this time. Relying on the inversion principle, I throw it away as garbage, because the opening and closing principle or directly "relying on abstract type principle" already contains the essence of relying on the inversion principle, while the dross of relying on the inversion principle is inherited by IoC. Of course, the pullback, I emphasize very much. Therefore, you need to master the abstract dependency principle (OCP), one-way dependency principle (including the learning of callbacks) and the minimum dependency principle (composite reuse principle, Dimit rule).

4: Fake goods, some packaging with hangers, NBA and Stance logo are slightly larger than the genuine goods, the color of the hangers is similar, and the font is slightly different. However, no matter what kind of goods, channel goods or company goods, the black-and-white ordinary version will have round anti-counterfeiting labels, and there is no fake one! The toe material is even more horrible and completely inconsistent. It is really black and deep snowflake ash, really white and light snowflake ash, and you can see the fake picture below. After all, there are 5 or 6 different materials woven together for real socks, and it is already very good to use 4 kinds of fake socks. I am only a few students, and the team version will not be able to identify them. However, the materials are obviously different when making goods, which cost about 10 yuan. I suggest you be careful.
一定是这样。

2. As a Cheng Yuan who has been engaged in machine learning for more than two years, seeing the computer series you recommended also thinks it is very unreliable. I have read most of the books you recommended. In particular, novice readers are not recommended to read "Introduction to Algorithms" and "Data Mining: Concepts and Technologies". These two books are thick and heavy. Although the content is also good, you will not know the year of the monkey when you finish reading them. What does a novice need? It's getting started! Secondly, have you really finished reading Python Core Programming? This book is not for Python newcomers. It is very thick and difficult. It is very unfriendly to newcomers. And if you just want to be AI, then many parts of this book don't need to be used. Is web development and Django framework really necessary for our AI engineers? No. Xiao Bai has no distinction between key and non-key points in a book. He spent a lot of time learning unnecessary knowledge, which really does more harm than good. Giving guiding and targeted recommendations is responsible recommendation.
