online users cannot register new users. The solution I first came up with was to restrict access to IP addresses. I analyzed the log. some ip attacks reached several thousand times, and some of them only accessed several times. There is no way to determine whether the ip address is a real user or an IP address that attacks the machine. I found a solution on the internet that allows an interface to limit the number of ip addresses to be accessed within a certain period of time. iptables -A INPUT

. After many contacts and discussions, he decided to further improve ALGOL 60 and use it as his doctoral thesis. This gave birth to Euler, the first language designed by worth. Although it is not very considerate in terms of practicality, It is very elegant in academics and creates a good foundation for the design of the compiler system. In addition, it also expands algo 60 to increase the table processing capability. For the above reason, Stanford Un
