Haiku

OpenBeOS (OBOS) is the new founded project on 18 August 2001 for the official continuation of BeOS as open source project. Not Shared Source of BeOS is rewritten to avoid licensed source code. Michael Phipps announced at the event WalterCon 2004 on 2004.06.19 the renaming of OpenBeOS in Haiku. Objectives of this project are the creation of a desktop operating system that requires no administration, is easy to use and has open source code. High Performance will be possible on older computers, even with complex applications. Only the BeOS modules Tracker as a file manager and the Deskbar as program menu has been adopted. All other components of the operating system are designed themselves or open source software.

As a development platform, Linux and BSD derivatives are used in future. Primary platform is the x86 32-bit and PowerPC architecture, SMP is supported. The first release of Haiku will be fully binary compatible for BeOS Release 5 (R5), offer advanced features and ease of use, containing numerous other improvements. A later release of this operating system will be support multi-user, 64-bit processors and use the new file system FutureHaikuFileSystem.

The minimum hardware requirements for Haiku are at least a Pentium II CPU 400 MHz with 128 MB of memory and 1 GB of free disk space. The operating system is mostly suitable for users and developers.

The third pre-release Haiku R1 (Alpha 3) was published in June 2011. About 800 bugs has been fixed since the previous alpha release. According to the official release notes, general improvements in stability and product features has been implemented.

Read and write performance for various file systems like btrfs, exFAT, ext2, ext3, ext4, NTFS, UDF and others were improved. The hardware support has been enhanced for technologies like IO-APIC, ACPI, video drivers, network drivers and USB. Support for PAE inside of the kernel allows physical memory beyond 4 GB now.

The Media Kit support for decoding and encoding for audio and video file formats has been improved. Email communication with IMAP is also supported by the mail system now.
