In late 1995, Theo de Raadt forked it from NetBSD. Besides the operating system as a whole, the project maintains portable versions of many subsystems, most notably OpenSSH, which are available as packages in other operating systems.  - Microsoft Windows (or simply Windows) is a metafamily of graphical operating systems developed, marketed, and sold by Microsoft. It consists of several families of operating systems, each of which cater to a certain sector of the computing industry with the OS typically associated with IBM PC compatible architecture. Active Windows families include Windows NT, Windows Embedded and Windows Phone; these may encompass subfamilies, e.g. Windows Embedded Compact (Windows CE) or Windows Server. Defunct Windows families include Windows 9x; Windows 10 Mobile is an active product, unrelated to the defunct family Windows Mobile.  - Hyperion Entertainment CVBA (formerly Hyperion Entertainment VOF) is a Belgian software company which in its early years focused in porting Windows games to Amiga OS, Linux and Mac OS. In 2001, they accepted a contract by Amiga Incorporated to develop AmigaOS 4 and mainly discontinued their porting business to pursue this development. AmigaOS 4 runs on the AmigaOne systems, Commodore Amiga systems with a Phase5 PowerUP accelerator board, Pegasos II systems and Sam440/Sam460 systems.  - Linus Benedict Torvalds (born December 28, 1969) is a Finnish software engineer who is the creator and, for a long time, principal developer, of the Linux kernel; which became the kernel for operating systems such as the Linux operating system, Android and Chrome OS. He also created the distributed revision control system Git and the diving logging and planning software Subsurface. He was honored, along with Shinya Yamanaka, with the 2012 Millennium Technology Prize by the Technology Academy Finland "in recognition of his creation of a new open source operating system for computers leading to the widely used Linux kernel". He is also the recipient of the 2014 IEEE Computer Society Computer Pioneer Award.  - Berkeley Software Distribution (BSD) is a Unix operating system derivative developed and distributed by the Computer Systems Research Group (CSRG) of the University of California, Berkeley, from 1977 to 1995.

Operating systems derived from the original BSD code remain actively developed and widely used.  - Windows NT is a family of operating systems produced by Microsoft, the first version of which was released in July 1993. It is a processor-independent, multiprocessing, multi-user operating system.  - The Amiga is a family of personal computers sold by Commodore in the 1980s and 1990s. Based on the Motorola 68000 family of microprocessors, the machine has a custom chipset with graphics and sound capabilities that were unprecedented for the price, and a pre-emptive multitasking operating system called AmigaOS. The Amiga provided a significant upgrade from earlier 8-bit home computers, including Commodore's own C64.  - The University of California, Berkeley, (also referred to as Berkeley, UC Berkeley, and Cal) is a public research university located in Berkeley, California. Founded in 1868, Berkeley is the oldest of the ten research universities affiliated with the University of California system, and is often cited as the top public university in the United States and around the world.  - Windows 9x is a generic term referring to a series of Microsoft Windows computer operating systems produced from 1995 to 2000, which were based on the Windows 95 kernel and its underlying foundation of MS-DOS, both of which were updated in subsequent versions. This includes all versions of Windows 95 and Windows 98. Windows ME is sometimes included.  - Tron (stylized as TRON) is a 1982 American science fiction action-adventure film written and directed by Steven Lisberger, based on a story by Lisberger and Bonnie MacBird and produced by Walt Disney Productions. The film stars Jeff Bridges as a computer programmer who is transported inside the software world of a mainframe computer where he interacts with programs in his attempt to escape, and Bruce Boxleitner, David Warner, Cindy Morgan, and Barnard Hughes star in supporting roles.  - Bruce William Boxleitner (born May 12, 1950) is an American actor, and science fiction and suspense writer. He is known for his leading roles in the television series "How the West Was Won", "Bring 'Em Back Alive", "Scarecrow and Mrs. King" (with Kate Jackson), and "Babylon 5" (as John Sheridan in seasons 25, 199498).  - Windows Server is a brand name for a group of server operating systems released by Microsoft. It includes all Windows operating systems branded "Windows Server", but not any other Microsoft product. The first Windows server edition to be released under that brand was Windows Server 2003. However, the first server edition of Windows was Windows NT 3.1 Advanced Server, followed by Windows NT 3.5 Server, Windows NT 4.0 Server, and Windows 2000 Server; the latter was the first server edition to include Active Directory, DNS Server, DHCP Server, Group Policy, as well as many other popular features used today.  - Armagetron Advanced is a multiplayer game in 3D that attempts to emulate and expand on the light cycle sequence from the film Tron . It is available for Linux , OS X , Microsoft Windows , AmigaOS 4 and OpenBSD as free software released under version 2 of the GNU General Public License .  - AmigaOS 4, (abbreviated as OS4 or AOS4), is a line of Amiga operating systems which runs on PowerPC microprocessors. It is mainly based on AmigaOS 3.1 source code developed by Commodore, and partially on version 3.9 developed by Haage & Partner. "The Final Update" (for OS version 4.0) was released on 24 December 2006 (originally released in April 2004) after five years of development by the Belgian company Hyperion Entertainment under license from Amiga, Inc. for AmigaOne registered users.  - PowerPC (a backronym for Performance Optimization With Enhanced RISC  Performance Computing, sometimes abbreviated as PPC) is a RISC instruction set architecture created by the 1991 AppleIBMMotorola alliance, known as "AIM". PowerPC, as an evolving instruction set, has since 2006 been named Power ISA, while the old name naturally lives on, as a legacy trademark for some implementations of Power Architecture based processors, and in software package identifiers.  - AmigaOS is the proprietary native operating system of the Amiga and AmigaOne personal computers. It was developed first by Commodore International and introduced with the launch of the first Amiga, the Amiga 1000, in 1985. Early versions of AmigaOS required the Motorola 68000 series of 16-bit and 32-bit microprocessors. Later versions were developed by Haage & Partner (AmigaOS 3.5 and 3.9) and then Hyperion Entertainment (AmigaOS 4.0-4.1). A PowerPC microprocessor is required for the most recent release, AmigaOS 4.  - Linux (pronounced or, less frequently) is a Unix-like computer operating system assembled under the model of free and open-source software development and distribution. The defining component of Linux is the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. The Free Software Foundation uses the name GNU/Linux to describe the operating system, which has led to some controversy.  - AmigaOne is a series of computers intended to run AmigaOS 4 developed by Hyperion Entertainment, as a successor of the popular Amiga series by Commodore International. Earlier models were produced by Eyetech, and were based on the "Teron" series of PowerPC POP mainboards. In September 2009, Hyperion Entertainment secured exclusive licence for AmigaOne name and subsequently new AmigaOne computers were released by A-Eon Technology and Acube Systems.  - Theo de Raadt (born May 19, 1968) is a software engineer who lives in Calgary, Alberta, Canada.
