Let me explain the role of these classes: MySubject class is our main object, Observer1 and Observer2 are objects that depend on MySubject, and Observer1 and Observer2 must change when MySubject changes. The AbstractSubject class defines a list of objects to be monitored, which can be modified: add or delete monitored objects, and when MySubject changes, it is responsible for notifying the objects that exist in the list. Let's look at the implementation code:

The data structure of the SYN cache is robust to attackers who attempt to overflow the HASH tablespace. Because its HASH value contains the port number and some password bits of the other party. Because stacks are a more efficient data structure than linked lists, stacks are used for SYN caching to improve speed. In Lemon's test, hosts under active attacks were able to establish connections with SYN cache and were only 15% delayed from normal time.

The "Tao" here is the strategic intention in BLM, the "heaven and earth" is the content of market insight, the "will" is the talent, and the "law" is the organizational structure and process. In fact, more than 3,000 years ago, our old ancestors put forward similar ideas, so I have been thinking about whether Harvard professors and IBM experts have studied Chinese traditional culture more deeply and thoroughly than we do.
