Mr. Sun Yimin's guidance to the practice team is not only reflected in practice, but also in the safety, life, study, life and other aspects of the team members. When this activity was slightly conceived, Mr. Sun repeatedly stressed with the captain the safety of the team members' stay in school, the transportation mode and route for two days out, etc. The teacher also repeatedly asked about the cost of this activity, and was very worried that some classmates would have family difficulties and could not afford the cost. On the day before the start of this summer's social practice activity, the team leader and vice-captain were worried that the content of the activity was not full enough. Teacher Sun Yimin immediately built a bridge for the team and introduced the team to Dalongfang Science Park. Within 9 days before and after the activity, two days of pre-contact and three days of probation, Mr. Sun Yimin took out the whole three days to accompany the team to three probation bases to accompany and guide the activity. Before and after each activity, in order to make the team members better transform what they have learned in practice into their own abilities, Mr. Sun Yimin encouraged the team members to actively ask questions and establish contact groups with successful people they met during the probation process, so as to facilitate better communication between the team members and role models.Scarcity mentality will seriously affect cognitive judgment ability, and a sharp decline in cognitive judgment ability will lead to shortsightedness.

Cookies to calculate the SYN-ACK serial number (that is, SYN? Cookies), the host must first combine some local password bits, a data structure including IP address and TCP port number, SYN initial sequence number, and some index data identifying the password bits. An MD5 digest is generated on top of all the above bytes, and then some bits are truncated from the hash value to put it into the SYN-ACK sequence number. Since the size of the sequence number is about a quarter of the total hash value, this truncation is necessary, but usually at least 3 bytes of hash bits are used for verification, which means that there are still nearly 2 24 possibilities to guess and verify cookies without knowing the password bits. In order to send out the hash value, some bits of cookies will reduce the upper limit value of MSS (Maximum Segment Length) contained in SYN and affect the index bits that identify the native password bits in the hash value.
