Course Introduction：The keyboard does not work in the virtual machine, mainly due to the incoming device not mapped, missing drivers or system settings errors. Solutions include: 1. Close the program that may occupy the keyboard and restart the virtual machine manager; 2. Check the keyboard enabled status in the virtual machine settings. VMware users need to ensure that the USB controller is connected, and VirtualBox users need to enable the USB controller and keyboard; 3. Try to reconnect the keyboard through "Device" → "USB Device" during runtime; 4. Install or update VMTools/GuestAdditions to provide necessary driver support; 5. The Linux system can manually load evdev or check whether the device file exists. Each step needs to be checked one by one, paying special attention to configuration and driver issues.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
