- How to automatically shut down and boot up a linux system

Some people pride themselves on keeping their computers up and running for long periods of time, and now we have kernel hotfixes that only require a machine shutdown if a hardware failure occurs. What I think is more practical is to save power by reducing wear and tear on moving parts and shutting down the machine when it is not needed. For example, you can wake up the backup server within a specified time and execute

- Detailed explanation of how to switch between Linux user mode and kernel mode
- User mode kernel mode is the state switching of the user program during running; when the user program encounters the application for external resources during operation, such as when the program needs to access: disk, memory allocation, network card, sound card, or even the motherboard LED indicator, it Switching from user mode to kernel mode will occur. For example, reading and writing files: open/read/write will switch from user mode to kernel mode; for example, applying for memory: C language: malloc/java language new. Every object needs to apply for memory space. ; Including select/poll/epoll, they are all system calls; the switching method is to switch from user mode to kernel mode.

- Linux system Fedora is developing well and the next version will be renamed Kernel
- Yes, there is no problem with your mouth. WindowsVista has been released a long time ago, and Linux developers are probably impatient, so they threw a bigger hydrangea than in previous years---the core developers of LinuxKernel said that they are willing to provide it to all companies. Driver development to improve the overall compatibility of Linux. Why do you have to encounter the problem of incompatibility of different drivers? But manufacturers don’t have to spend a penny to obtain drivers. All they have to do is to provide relevant information about the hardware as much as possible. In fact, it is best to give away their hardware to developers. for detailed testing. The purpose of the driver being written by Linux Kernel core developers is that this code can be put into the new Linux released at any time.
