"Is-A" refers to the "one" of one class and belongs to another class, while "Has-A" is different, which indicates that a certain role has a certain responsibility. A common reason for the wrong use of inheritance instead of aggregation is to mistakenly treat "Has-A" as "Is-A". For example:

That is to say, don't let a single interface take on too many responsibilities, but should separate each responsibility into multiple specialized interfaces for interface separation. Too bloated an interface is a kind of pollution to the interface.

Only in the last ten kilometers, I felt slightly pushing my feet, took off my shoes to move my socks, and the feeling of trying again did not decrease. This kind of situation has also occurred in cross-country drivers before. There are no more than two reasons. One is that the shoes are not suitable or the shoelaces are slightly loose. The other is that the socks do not fit. The third is that the feet slide forward when going downhill. Of course, either of the above situations occurs when the slope is downhill. I asked my friends, and two of them had the same situation as me. Judging from experience, it should not be the cause of shoes and socks, it is purely caused by downhill, and it may be that one's shoelaces are not fixed to one's feet.

Is it TCP to try to send enough SYN packets and run out of backlog? The purpose of SYN flooding. The attacker added the source IP address to the SYN packet, which would not cause the host to remove the assigned TCB from the SYN-RECEVIED state queue (because the host would respond to the SYN-ACK). Because TCP is reliable, the destination host will wait quite a long time before disconnecting the half-open connection and removing the TCB from the SYN-RECIEVED queue. During this period, the server will not be able to respond to legitimate new TCP connection requests from other applications. Figure 2 shows a simple TCP? The process of a SYN flooding attack.
