Another expression of the minimum knowledge principle is to communicate only with direct friends. As long as there is a coupling relationship between classes, it is called a friend relationship. Coupling is divided into dependency, association, aggregation, combination, etc. We call classes that appear as member variables, method parameters, and method return values direct friends. Local variables and temporary variables are not direct friends. We require unfamiliar classes not to appear in the class as local variables.
1. As a math student, I have studied math for four years, and I don't agree with the bibliography you gave at random. First, there is no step type and it is unfriendly to beginners. Your title and the purpose of writing this series are probably for Xiaobai to see. So, may I ask, a Xiaobai needs to see the principle of mathematical analysis? ? Is it necessary to look at Princeton Calculus Principle to learn artificial intelligence? ? In my shallow understanding, the biggest difference between mathematical analysis and advanced mathematics is the same theorem. High numbers only require that they can be used. Mathematical analysis is rigorous and will definitely give proof. However, for the mathematics needed in most artificial intelligence, you need to prove the correctness and completeness of this theorem in your work? ? I'm afraid the project will be closed long ago when you prove it. You replied to me that this is only a bibliography, not a recommended bibliography, but most of the following comments decided to give up when they saw the book list. If you put these books out, it will be instructive to those who read your articles. I think you are misleading people. Second, I have roughly deduced from the number of references you have made that you may not have a framework for the mathematics of the whole artificial intelligence, otherwise there would not have been such irresponsible recommendations. However, out of respect for you, I did not question your ability. I only gave a brief recommendation in the comments on the suitable math bibliography for beginners.

Centos7, The service is no longer started using init-style scripts, Instead, the unit file is used, Therefore, commands like service iptables start can no longer be used in centos7, Therefore, service iptables save cannot be executed. At the same time, firewall is used to replace the original iptables service in centos7, but don't worry, we just need to install iptables and iptables-services through yum source (iptables are usually installed by default, but iptables-services are not installed by default in centos7). After installing iptables-services in centos7, the rules can be saved by the service iptables save command, as in centos6, and the rules are also saved in the/etc/sysconfig/iptables file.
在这个不爱书只爱钱的年代，“深夜书店”能活到今天，实属不易，有好事者分析原因，可能有二：第一，店主老白太帅且有脑，大有妖道风范。第二，上至宋代孤本，下至高考真题，书店藏书保罗万象。凡进过此间书店的人，都像吸了毒一样频频光顾，更有甚者，称其能让人脱胎换骨，重新做人。不过也有流浪汉称，“深夜书店”里的书会吃人，据说还是亲眼所见……
I won't repeat much about the profound and pure theoretical explanation here. After all, the written explanation is too lenient. I'm going to say something simple and visible here. Let's start now.

At present, at least 19 provinces have implemented "dysmenorrhea leave", allowing female employees to rest for one or two days during special periods. However, the regulations vary from place to place. Some regulations only need to provide certificates from medical institutions, while others limit the types of work, allowing only female employees in "third-level physical labor intensity" and "long-term standing and walking work" to take "dysmenorrhea leave".

For easier management, We can also create custom chains in a table, Place the rules set for an application in this custom chain, But custom links cannot be used directly, It can only work if it is called as an action by a default chain. We can imagine that, Custom chain is a relatively "short" chain. The rules on this "short" chain are all formulated for an application program. However, this short chain cannot be directly used, but needs to be "welded" on the default definition chain of IPTables before it can be used by IPTables. This is why the default definition "chain" needs to refer to "custom chain" as "action". This is a later remark. We will talk about it later. We can understand it more clearly in actual use.
