The term was coined by the programmers at MIT's Project MAC.According to Fernando J. Corbató, who worked on Project MAC around 1963, his team was the first to use the term daemon, inspired by Maxwell's demon, an imaginary agent in physics and thermodynamics that helped to sort molecules, stating, "We fancifully began to use the word daemon to describe background processes that worked ...
Docker Compose is a tool for defining and running multi-container Docker applications. [29] It uses YAML files to configure the application's services and performs the creation and start-up process of all the containers with a single command.
Here is a simplified view of the Mac OS X Tiger system startup on a PowerPC Mac (on an Intel Mac, EFI replaces Open Firmware and boot.efi replaces BootX): Open Firmware activates, initializes the hardware, and then loads BootX. BootX loads the kernel, spins the pinwheel cursor, and loads any needed kernel extensions (kexts). The kernel loads ...
UnrealIRCd is an open-source IRC daemon, originally based on DreamForge, and is available for Unix-like operating systems and Windows.Since the beginning of development on UnrealIRCd c. May 1999, many new features have been added and modified, including advanced security features and bug fixes, and it has become a popular server.
systemd is the first daemon to start during booting and the last daemon to terminate during shutdown. The systemd daemon serves as the root of the user space's process tree; the first process (PID 1) has a special role on Unix systems, as it replaces the parent of a process when the original parent terminates. Therefore, the first process is ...
Netdata consists of a daemon that, when executed, is responsible for collecting and displaying information in real-time. It is mostly written in C, Python and JavaScript, and aims to use minimal system resources. It can be run on any Linux system to monitor any system or application, and is capable of running on PCs, servers, and embedded Linux ...
This behavior is enforced in some variations of cron, such as that provided in Debian, [8] so that simply restarting the daemon does not re-run @reboot jobs. @reboot can be useful if there is a need to start up a server or daemon under a particular user, and the user does not have access to configure init to start the program.
It supports saving the virtual machine state while all programs are running. Guest operating systems do not need patching to run inside QEMU. The virtual machine can interface with many types of physical host hardware, including the user's hard disks, CD-ROM drives, network cards, audio interfaces, and USB devices. USB devices can be emulated ...
