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:?

Now, she has to lie in bed all day long, and she can already start walking downstairs or cooking breakfast for herself. "When I cooked my first meal again, I felt full of accomplishment. After eating, I didn't even have time to put chopsticks on the plate, so I climbed onto the bed and passed out. As tired as just running two marathons."
The Liskov Substitution Principle (LSP) is one of the basic principles of object-oriented design. The Richter substitution principle says that wherever a base class can appear, subclasses can certainly appear. LSP is the cornerstone of inheritance reuse. Only when derivative classes can replace base classes and the functions of software units are not affected can base classes be truly reused, and derivative classes can also add new behaviors to base classes. The Richter substitution principle is a supplement to the "open-close" principle. The key step to realize the "open-close" principle is abstraction. The inheritance relationship between the base class and the subclass is the concrete realization of abstraction, so the Richter substitution principle is the specification of the concrete steps to realize abstraction. --From Baidu

Judging from the good aspect of this regulation, it lets the vast number of migrant workers know that there is a lower limit to their work, which can provide protection to the bottom-level workers who are not well off and enhance their legal awareness. On the other hand, the increase in the wages of migrant workers is also conducive to narrowing the gap between the rich and the poor in urban and rural areas and promoting the economic development of villages, towns and cities. In addition, raising wages can, on the one hand, normalize consumption. White-collar workers' high wages will lead to more disguised consumption. As we all know, some rich people are completely shocking in consumption. Migrant workers are sighing. If only they could have a corner of others, this abnormal consumption is abnormal and cannot be wasted and squandered so much. However, the wage increase of migrant workers will be used for more basic consumption and improve their lives. They have always been thrifty and know how to cherish it, which can guide the normalization of consumption.
We are not in a hurry to write the code, We can look at a column first. For example, there are many front-end recruitment information in QQ Group recently. I have also received many phone calls from companies or headhunters asking me if I need to find a job. Of course, I don't plan to find a job now, because I have more spare time to deal with my own affairs, so I also think it is quite good ~ Let's look at the interview process in recruitment first. Interview process for many large companies, such as BAT, the interview process is actually very similar. Therefore, we can summarize the interview process as follows:
CCTV News (Focus Interview): The goal of "Two Hundred Years" is not only the grand blueprint for China's development, but also the call of the times for China to move forward. In General Secretary Xi Jinping's 19th Congress report, the "two hundred years", especially the goal of the second hundred years, has been given new connotations. The original goal of building a prosperous, democratic, civilized and harmonious socialist modern country by the time New China is founded 100 years ago is defined as "a prosperous, democratic, civilized, harmonious and beautiful socialist modern power". A word has been added here, beautiful. One word has been changed, powerful country. Obviously, the requirements of the new goals are even higher. Not only that, the task of achieving new goals is also heavier. The new second century goal is divided into two stages. The first stage is from 2020 to 2035. In 15 years, socialist modernization will be basically realized. The second stage is from 2035 to the middle of this century, striving for another 15 years to finally build our country into a prosperous, democratic, civilized, harmonious and beautiful socialist modern power. So, how should we understand this far-reaching strategic arrangement for the development of socialism with Chinese characteristics in the new era?
