It is used to determine whether the system is idle during code compilation. It must be used in both Linux and Windows. Initially, the getsystemtimes function was used for determination. Later, it was found that it could not be used in Win2000. Later, we switched to the performance API, which provides four interfaces: WMI, ODBC, registery, and PDH. Registry seems to be the best choice, but in fact there are too few materials available and it is useless

Most people usually execute the reload (SYS) statement just to be able to modify the Python default character set, which is the ability to call sys.setdefaultencoding (). However, if you execute reload (SYS)in idle, you will cause the next failure to execute any commands.At first there was nothing to do with the problem, and later on StackOverflow it was seen that someone had said it. This is because idle,

Idle is a python Development Environment officially recommended by python. It is very convenient. It supports syntax highlighting and Automatic completion, and supports one-click operation.
Take two screenshots to see the effect. The first one is the Editor interface and the second is the running environment interface.

When the Linux kernel prints "bug: Scheduling while atomic" and "Bad: scheduling from the idle thread" errors, it usually calls sleep functions in the interrupt processing function, such as semaphore, mutex, sleep, and other sleep functions, while the Linux kernel requires that the system height and preemption are not allowed during Interrupt Processing, and other tasks can be performed only after the interrupt processing is completed. Therefore, it m
Use a client tool, such as securecrt, to connect to a linux server. some of them may be disconnected after a period of time without any operation. This is mainly because the vro and firewall exist between the client and the server, and the idle connection will be disconnected after the specified time for its own security. Or the server is set to disconnect idle connections. There are two solutions: one is t
