Mir
Mir is a display server and compositor for Linux-based systems, developed by Canonical as a replacement for the X Window System. It provides a modern, secure, and efficient way to manage graphical user interfaces, handling input, output, and window management. Mir is designed to work with Wayland protocols and is often used in embedded systems, IoT devices, and Ubuntu's Unity desktop environment.
Developers should learn Mir when working on Linux-based graphical applications, especially for embedded or IoT projects where lightweight and secure display management is crucial. It is particularly useful for creating custom user interfaces in Ubuntu environments or when targeting devices with limited resources, as it offers better performance and security compared to older systems like X11.
