This chapter is the last lecture on design patterns. It will talk about the third design pattern-behavioral pattern, with a total of 11 types: policy pattern, template method pattern, observer pattern, iterative sub-pattern, responsibility chain pattern, command pattern, memo pattern, state pattern, visitor pattern, intermediary pattern and interpreter pattern. I have been writing about design patterns for a long time. At last it's halfway through, Writing a blog post is a very time-consuming thing, Because I have to be responsible for the readers, Whether it's graphs, codes, or representations, Everyone hopes to write it as clearly as possible so that readers can understand it. I think both I and the readers hope to see high-quality blog posts come out. Starting from myself, I will stick to it and update it continuously. The continuous motivation comes from the continuous support of readers and friends. I will do my best to write every article well! I hope everyone can give opinions and suggestions continuously and jointly create a perfect blog post!
Chapter 29
《远古入侵第二季》剧中人物发生重大变化：首先，Lucy Brown扮演的女主角Claudia Brown将不会在第二季中出现，取而代之的是一名新角色：Jennifer。和标准的英国淑女Claudia不同，新角色Jennifer美艳性感，大胆开放。根据Lucy Brown的介绍，Jennifer和Claudia应该是同一个人，因为第一季中时间线被改变，人物身份也随之变化。其次，将增加两名常规角色。Oliver Leek（Karl Theobald扮演）将取代被错误的时间线吞没的Claudia，成为Lester的新助手。他可能是本季中的主要反派角色。Caroline Steel（Naomi Bentley扮演）则是Connor的新女友。这个心眼里只想着钱的女人非常讨厌蜥蜴，也非常讨厌 \"准情敌\" Abby，下决心要 \"除之而后快\" 。有迹象表明，Caroline很可能暗中替Oliver Leek做事。

On the other hand, the rapid development of the application of the Internet seven-layer model has diversified the attack targets of DDoS. From the web to DNS, from the three-layer network to the seven-layer application, from the protocol stack to the application App, the endless new products have also given hackers more opportunities and breakthrough points.

Often, the construction cost of a business's DDoS defense system is larger than the cost or benefit of the business itself, which makes many start-up companies or small Internet companies unwilling to make more investment.
