How should we defend against this attack? First of all, as users, we try our best to download APP from regular channels and surf the Internet in a civilized manner, and try our best not to make broilers. Secondly, as a service manufacturer, when the server is attacked by DDoS, we try our best to improve the processing capacity of the server. When the processing capacity of our server is greater than that of the attacker, these attacks are nothing to the server. Finally, under normal circumstances, the processing capacity of our server is generally lower than that of the attacker. In view of this situation, there are currently the following methods: 1. Violent methods, such as setting an access frequency threshold, and rejecting when the number of accesses per IP unit time exceeds this threshold; For a certain service, if the instantaneous request is too large, choose to directly refuse to ensure the normal operation of other services; This method may result in normal users not being able to use it. 2. Verification code. In order to prevent normal users from being injured by exposure methods, at present, service providers will send verification codes to "users" when receiving a large number of requests. If it is a real user, it will input verification codes, but if it is a broiler, it will not. Through this method, the real user and the broiler will be distinguished.

NBC过去拿下电影《绝地战警2 Bad Boys II》角色Sydney “Syd” Burnett的个人衍生剧试映集《洛城战警 L.A.’s Finest》，但该项目最终没被预订。但是经过制片公司Sony jijidy.com Pictures电视部门的销售后，《洛城战警》以13集首季被有线台Spectrum收归旗下，预定美国时间5月13日首播。 在《绝地战警2》中饰演Syd一角的演员是Gabrielle Union，剧集版将由她继续演出。她是Marcus Burnett（Martin Lawrence饰）的妹妹，亦是美国缉毒局的卧底探员。另外在片中，Sydney与Mike Lowrey（Will Smith饰）是情侣。 《洛城战警》里Syd成了洛杉矶警局的警探，原本可以扔下过去，享受生活的她却可能因为新拍档Nancy McKenna而令事情变得复杂。在2000-02年主演过《末世黑天使 Dark Angel》的Jessica Alba将饰演Nancy McKenna，Nancy高中后参加了陆军，在伊拉克及阿富汗待了10年之久；回国后她当上了警探，与丈夫一同抚养两个前青少年期的继子。 其他角色包括Ben Walker﹑Ben Baines（Zack Gilford及Duane Martin饰演，下同）﹑Patrick McKenna（Ryan McPartlin）﹑Isabel “Izzy” McKenna（Sophie Reynolds）及Joseph Vaughn（Ernie Hudson）。
Pass on values. The same event can be interpreted from different perspectives, which is one of the manifestations of values. For example, "Jiang Ge's Murder" can be viewed from the perspectives of condemnation of Liu Xin, attitude towards Jiang Ge's mother, hatred of the murderer, etc. Which one to choose and how to interpret it is to embody different values.

Javascript neither supports abstract classes nor has the concept of interfaces. Therefore, be very careful when using the state mode. If you forget to implement the buttonWasPressed method for a state subclass when writing a state subclass, an exception will be thrown when the state switches. Because Context always delegates requests to the buttonWasPressed method of the state object. Therefore, let the abstract method of the abstract parent class throw an exception directly, which will be found at least during the program run.
