What is Haiku?● Operating System
● Desktop focused (x86)● Free Software (MIT licence)● From the ground up (no Linux, no X11)● Inspired by the BeOS
● C/C++● Keep It Smart & Simple● Binary compatibility as goal for R1

History● Started 2001 as OpenBeOS● June 2002: NewOS Kernel forked● June 2004: New name: Haiku● Sept. 2009: R1/alpha1

Features● Modular kernel
● Preemptive SMP● Not a µkernel as in Tanenbaum
● Just enough POSIX● C++ API
● Kits (App, Support, Interface...)● OpenBFS
● Typed and indexable extended attributes● Live Queries

Community● Spawned from the BeOS community
● Macintosh and Amiga roots● Used to proprietary systems● But also free as in beer (BeOS R5 Personal Edition)
● Newcomers● Developers & users seeking lighter FOSS OS● Academia
– Google Summer of Code– University of Auckland (Auckland Layout Model, Ph.D ?)

Why MIT licence ?● After Be, Inc. demise...
● Need to maintain the BeOS spirit– → Rewrite
● Fear of proprietary vendor failure and focus shifts● Need to own the source code
● Need for a FOSS licence● Still allows easy commercial attempts● You cannot avoid GPL vs BSD trolls anyway :^)

FOSS projects reuse● Why reinvent the wheel ?
● Concentrate on the project itself● Existing projects
● Maintained● Portable● Compatible licence-wise
● When correctly integrated appear as native

FOSS projects reuse examples● Anti-Grain Geometry (drawing in app_server)● FreeType 2 (font rendering in app_server)● GNU tools & glibc● FreeBSD network drivers (+ abstraction layer)● FFmpeg (LGPL) → libavcodec media add-on● Translation Kit add-ons using libpng, libjpeg...● And many others...

Academic value● Full Operating System from kernel to GUI
● OO design and C/C++ courses● SMP, threading and synchronization primitives● VFS, OpenBFS design
● Smaller than GNU/Linux while still real-world● Easier to understand
● Clean Device Driver Interface● Driver sample code + userland access
● PowerPC, ARM, MIPS and m68k ports
