Recently the company's server time has been inaccurate, looked for several times the server, after testing Shanghai Jiaotong University's still count, address:ntp.sjtu.edu.cn (Shanghai Jiaotong University Network Center NTP server address)202.120.2.101 (Shanghai Jiaotong University Network Center NTP server address)So through the crontab do timed tasks, let every 5 minutes synchronization time:[Email protected] ~]# crontab-lTen * * * */usr/sbin/ntpdate-u ntp.sjtu.edu.cn[Email protected] ~]#Other
){} ~wp(); SmartPointer operator = (T* other);private: T* m_ptr;}
When assigning values to SmartPointer, you must add one to the reference count of the Object. Therefore, you must overload the assignment operator:
SmartPointer
SmartPointer
: Operator = (T * other) {if (other! = Null) {m_ptr = other; // point to this object other-> incStrong (); // other reference count plus one} return * this ;}
During structure analysis, the decStrong of the object is called to red

2. What makes cloud computing?
The National Institute of Standards and Technology (NIST) defines five key features, three service models, and four deployment models for cloud computing. As shown in 1, detailed descriptions will be provided later.
2.1 key features of cloud computing
The five key features presented by cloud services represent their relationships and differences with traditional computing methods:
