Conclusion 1: as long as one Nat is full cone Nat, bidirectional communication can be realized.Conclusion 2: as long as the nat on both sides are not classified as Nat, two-way communication is also possible. In other words, as long as the nat on both sides belong to the cone Nat, two-way communication can be achieved.Conclusion 3: Nat on one side belongs to the elastic Ric Nat, and Nat on the other side belongs to the restricted cone, which can also be used for bidirectional communication.Concl

In a worksheet, there are usually numbers, letters, and Chinese characters. So, when we edit different types of cells, we need to constantly switch between Chinese and English input method, which not only reduces the efficiency of editing, but also makes people feel trouble.

As a beginner in PHP, I have been confused about the reference of PHP for a long time. I carefully read the user manual and did some experiments tonight, and finally understood the principles and details, in particular, = operator for different types of behavior. First, explain the behavior of the value assignment operator =. let's look at the example below: The code is as follows: $ I = 0; $ J = $ I; $ J

The assignment operator in PHP performs different actions on different data types. First, explain the behavior of the value assignment operator =. See the following example: Copy the code as follows: $ i0; $ j $ I; $ j0; echo $ j; print the output 0 $ arrarray (0); $ arr2 $ arr; $ arr2 [0 First explains the behavior of the value assignment operator =. See the fol

is the Unix filename and the file itself-the variable name is the directory entry, and the variable content is the file itself. References can be seen as tight connections in Unix file systems. A little explanation of what "references are": int i = 0; int j = 0; int *p = i; p = j; In the above code, p is a pointer to the memory address of I, and *p is the content, and the p=j point changes the direction of the P pointer, and the *P=111 expression changes the contents of I. While PHP is not, the

performance provides some guidance for designing a topic structure: If you find yourself having thousands of themes, it might be wise to merge some fine-grained, low-throughput topics into coarse-grained topics, which avoids the spread of partitions.However, performance is not the only problem we care about. In my opinion, more important is the data integrity and data model of the subject structure. We'll discuss these in the remainder of this article.The topic equals the collection of events o
