D-Bus (short for "Desktop Bus" [4]) is a message-oriented middleware mechanism that allows communication between multiple processes running concurrently on the same machine. [5] [6] D-Bus was developed as part of the freedesktop.org project, initiated by GNOME developer Havoc Pennington to standardize services provided by Linux desktop environments such as GNOME and KDE.
Components of some Linux desktop environments that are daemons include D-Bus, NetworkManager (here called unetwork), PulseAudio (usound), and Avahi.. In multitasking computer operating systems, a daemon (/ ˈ d iː m ən / or / ˈ d eɪ m ən /) [1] is a computer program that runs as a background process, rather than being under the direct control of an interactive user.
The GNOME project decided that the 3.0 release would be free of ORBit and Bonobo, meaning that a D-Bus AT-SPI solution was required. [6] [7] In an effort to move AT-SPI forward, a D-Bus project was started in November 2006. This took the form of a performance and design review available on the GNOME wiki.
The NetworkManager project was among the first major Linux desktop components to utilize D-Bus and HAL extensively. Since June 2009, however, NetworkManager no longer depends on HAL, and since 0.9.10 (ca. 2014), neither does it require the D-Bus daemon to be running for root operation. [8]
IBus employs D-Bus to communicate among ibus-daemon, services, and IM clients such as terminal emulators, editors and web browsers. ibus-daemon manages all clients and services by receiving registrations from services, and sending D-Bus message to corresponding services and IM client. It implements XIM protocol, and has GTK and Qt input method ...
Ford CEO Jim Farley has a message to the Trump administration: Our profits will be run over if you hit the world with tariff hikes."There's no question that tariffs at 25% level from Canada ...
From January 2008 to December 2012, if you bought shares in companies when Richard B. Myers joined the board, and sold them when he left, you would have a 4.8 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
HAL is a single daemon responsible for discovering, enumerating and mediating access to most of the hardware on the host computer. Applications communicate with HAL through the D-Bus IPC mechanism, which abstracts the hardware behind an object-based RPC mechanism.
