addition, Calise is a great application, worthy of our attention and support. As I mentioned earlier, it has undergone a patchy and difficult period in the past few years, so I really hope that this project will go on.

undergone a patchy and difficult period in the past few years, so I really hope that this project will go on. RedshiftIf you want to reduce the pressure on the eye caused by the screen, you probably have heard of F.lux, a free proprietary software that modifies the brightness and color of the display based on the time of day. However, if you really prefer open source software, an alternative scenario is: redshift. Inspiration from F.lux,

. 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
