Adapter pattern of the class: When you want to convert a class into a class that meets another new interface, you can use the adapter pattern of the class to create a new class, inherit the original class, and implement the new interface.For this reason, we can encapsulate a global publish-subscribe mode object. The following code:　传统豫剧《三哭殿》是一出久演不衰、唱段广为流传、在群众中很有影响力的唐（喜成）派名剧。将它搬上银幕，不仅满足了当代广大群众的文化需求，而且，对于传承豫剧唐派艺术、保留非物质文化遗产，有着不可低估的历史意义。Extraction structure or pattern: It is often necessary to store the knowledge, extraction structure or pattern in the professional field in a better way. For example, expert developers make good use of design patterns.How do I develop this? The critical strike rate in position 6, don't think about changing the explosive injury, I will lose the critical strike rate if I change the explosive injury. . .SYN attack is a kind of DOS attack. It takes advantage of TCP protocol defects and consumes CPU and memory resources by sending a large number of semi-connection requests. SYN attacks can not only affect hosts, but also harm network systems such as routers and firewalls. In fact, SYN attacks can be implemented as long as these systems turn on TCP services no matter what systems are targeted. As can be seen from the above figure, the server receives the connection request (syn=j), adds this information to the unconnected queue, and sends the request packet to the client (syn=k, ack=j+1), then enters the SYN_RECV state. When the server does not receive an acknowledgement packet from the client, it retransmits the request packet and does not delete this entry from the non-connection queue until the timeout. With IP spoofing, SYN attacks can achieve good results, Typically, clients forge a large number of non-existent IP addresses in a short period of time, SYN packets are continuously sent to the server, and the server replies to the confirmation packets and waits for the confirmation of the customer. Since the source address does not exist, the server needs to continuously resend until it timeout. These forged SYN packets will occupy the unconnected queue for a long time, normal SYN requests will be discarded, the target system will run slowly, and in serious cases, the network will be blocked or even the system will be paralyzed.……好个白起。
