DDoS attacks are not as simple as we think, and are not something that Python programmers can do.To understand the hacker's use of DDoS attacks, we must know what is the most difficult reason to implement a DDoS attack?A simple sentence summarizes: "Python programmers have to master a certain intrusion skills." ”Here I describe the principles of a common attack tool on the network:Trin00Tribe Flood NetworkA deeper understanding of the principle of DDoS attacks:Understanding of the TRIN00 structu

------Multi-threaded security issuesCause: When when multiple statements are working on the same thread to share data, one thread executes only a portion of the multiple statements, has not finished executing, and another thread participates, resulting in a shared data error. WORKAROUND: Statements that share data on multiple operations can only have one thread complete, and other threads cannot participate in execution during execution. The practice is to use synchronous code blocks:Synchronize

subclass of an external class or interface with Content anonymous objects. When do you use anonymous internal classes? An anonymous inner class can be passed as a parameter, typically when the usage method is an interface type parameter, and there are no more than three methods in the interface. Because the name of the constructor must be the same as the class name, and the anonymous class does not have a class name, the anonymous class cannot have a constructor and instead passes the construc

one-dimensional arrays contain 3 elements of type int2. StorageL Two-dimensional arrays are stored in rows, first the elements of the first row, and then the elements of the 2nd row. For example, the order in which int a[2][3] is stored is: a[0][0]→a[0][1]→a[0][2]→a[1][0]→a[1][1]→a[1][2]3.
