In the dense demand bombing (the demand itself has a certain rationality, not including that should not be rejected by the demand), while there are a lot of spontaneous drive to do things, interaction designers how to make reasonable design priority

The last time we wrote to role Rights Management, we set the role to be used, and we then wrote about the relationship between the user and the role. Roles and Permissions: Many-to-many A role can have multiple permissions, and a permission can be

This tool requires a C library for compilation. Of course, it is installed using (g) make. (In BSD, you need to add additional header files: if_wavelan_ieee.h and if_aironet_ieee.h for installation .) This tool displays wireless link quality, link level, and noise. Its latest version can

. As we all know,linux system everything is a file, so each process has its file descriptor, The Nginx process writes its own file descriptor to the Nginx.pid, and we need to tell Nginx to reopen a new log file (the configuration details of the log file can be seen here, simply by letting the log record what. So we need this directive:kill -USR1 `cat ${pid_path}`This instruction means: first cat to Nginx PID, is an integer, and then send the signal

that, with the existence of VFS, cross-file system operations can be performed, and "Everything is a file" in Unix/Linux can be implemented. Figure VFS synergy with other kernel modules in the kernel Three file system operations: Registration: Report to the kernel and declare that it can be supported by the kernel. It is generally registered when the kernel is compiled; it can also be manually registered
