The principle is that syn messages are first responded to syn_ack by DDOS protection system. With a specific sequence number (recorded as a cookie). The real client returns an ack and the Acknowledge number is cookie+1. The fake client will not respond. In this way, we can know that the clients corresponding to those IP are real and add the real client IP to the white list. The next access passes directly, while other forged syn messages are intercepted. The following is a schematic diagram of protection:?
For example, the above is only a simple literal quantity structure. All member variables above are accessed through Singleton, but it is not a single mode. Because the monomer pattern has a more important feature, that is, it can be instantiated only once. The above is only a class that cannot be instantiated, so it is not a monomer pattern. Object literal quantity is one of the methods used to create a single pattern;

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.
