This is October 2014, when I was a company researcher at Lujiazui Finance House, when I first made a company research report, I encountered the scene. Three years have passed, and the situation at that time is still engraved in my heart. I clearly remember that in order to make this report, I spent half a month writing more than 20 pages of company research report, and spent a week staying up late until 11 o'clock to write a 70-page PPT with dense pictures and words, and a lecture draft of more than 10 pages. I also clearly remember the handsome boy who carried the bag halfway, with cold facial features and a young and fragile heart in his speech.

杨长帆本没指望用那种标语式的话能钓来多少搞心学的人，只因心学小圈子向来曲高和寡，你进了这个圈子，多半在朝中也有不错的地位，没必要来这里。
这是关于一个女人的故事；这是一个关于多少有些与众不同的母亲的故事；这是一个有关拯救“富二代”的故事；这是一个，题旨健康、感人向上，多少有点呼唤和励志的故事。这是一部根据真实事件再度加工创作而成的长篇电视连续剧。都市、乡村、家庭、伦理……
In fact, each design pattern is a very important idea, which looks very familiar. In fact, it is because what we have learned is involved. Although sometimes we don't know it, it is actually reflected everywhere in Java's own design, such as AWT, JDBC, collection class, IO pipeline or Web framework, in which design patterns are everywhere. Because of our limited space, it is difficult to talk about every design pattern in great detail, but I will try my best to write down the meaning clearly in the limited space and space so as to make everyone understand better. If there is no accident in this chapter, it should be the last talk of the design pattern. First of all, it should be the figure at the beginning of the previous article:
The module mode uses an anonymous function that returns an object. Inside this anonymous function, private variables and functions are first defined for use by internal functions, and then an object literal quantity is returned as the value of the function. The returned object literal quantity only contains properties and methods that can be exposed. In this way, external use of the method can be provided; Since the public method in the return object is defined inside the anonymous function, it can access private variables and functions inside.
At present, there are many open source DDOS attack tools (low attack cost is also one of the reasons why DDOS attacks are easy to occur), but there are not many DDOS attack defense tools. Fastnetmon is an efficient analysis tool for DDOS attacks based on various packet grabbing engines, which can detect and analyze abnormal traffic conditions in the network and notify or block attacks through external scripts. A visual DDOS security early warning system can be built by integrating InfluxDB and Grafana.
