Development
Haiku is developed in C++ and provides an object-oriented API.
The modular design of BeOS allowed individual components of Haiku to initially be developed in teams in relative isolation, in many cases developing them as replacements for the BeOS components prior to the completion of other parts of the operating system. The original teams developing these components, including both servers and APIs (collectively known in Haiku as "kits"), included:
- App/Interface – develops the Interface, App and Support kits.
- BFS – develops the Be File System, which is mostly complete with the resulting OpenBFS.
- Game – develops the Game Kit and its APIs.
- Input Server – the server that handles input devices, such as keyboards and mice, and how they communicate with other parts of the system.
- Kernel – develops the kernel, the core of the operating system.
- Media – develops the audio server and related APIs.
- MIDI – implements the MIDI protocol.
- Network – writes drivers for network devices and APIs relating to networking.
- OpenGL – develops OpenGL support.
- Preferences – recreates the preferences suite.
- Printing – works on the print servers and drivers for printers.
- Screen Saver – implements screen saver functionality.
- Storage – develops the storage kit and drivers for required filesystems.
- Translation – recreates the reading/writing/conversion modules for the different file formats.
A few kits have been deemed feature complete and the rest are in various stages of development.
The Haiku kernel is a modular hybrid kernel and a fork of NewOS, a modular kernel written by former Be Inc. engineer Travis Geiselbrecht. Like the rest of the system it is currently still under heavy development. Many features have been implemented, including a virtual file system (VFS) layer and rudimentary symmetric multiprocessing (SMP) support.

Famous quotes containing the word development:
“As a final instance of the force of limitations in the development of concentration, I must mention that beautiful creature, Helen Keller, whom I have known for these many years. I am filled with wonder of her knowledge, acquired because shut out from all distraction. If I could have been deaf, dumb, and blind I also might have arrived at something.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“A defective voice will always preclude an artist from achieving the complete development of his art, however intelligent he may be.... The voice is an instrument which the artist must learn to use with suppleness and sureness, as if it were a limb.”
—Sarah Bernhardt (1845–1923)
“The development of civilization and industry in general has always shown itself so active in the destruction of forests that everything that has been done for their conservation and production is completely insignificant in comparison.”
—Karl Marx (1818–1883)
