Ximian, Inc. was an American company that developed, sold and supported application software for Linux and Unix based on the GNOME platform. It was founded by Miguel de Icaza and Nat Friedman in 1999 and was bought by Novell in 2003.

rtos is a real-time operating system (RTOS), created in about 1982 by Alfred Chao, and developed and marketed for the first part of its life by his company Software Components Group (SCG). In the 1980s, rtos rapidly became the RTOS of choice for all embedded systems based on the Motorola 68000 series family architecture, because it was written in 68000 assembly language and was highly optimised from the start. It was also modularised, with early support for OS-aware debugging, plug-in device drivers, Internet protocol suite (TCP/IP) stacks, language libraries, and disk subsystems. Later came source code level debugging, multiprocessing support, and further computer networking extensions.
Novell, Inc. was an American software and services company headquartered in Provo, Utah. Its most significant product was the multi-platform network operating system known as Novell NetWare. Under the leadership of chief executive Ray Noorda, NetWare became the dominant form of personal computer networking during the second half of the 1980s and first half of the 1990s. At its high point, NetWare had a 63 percent share of the market for network operating systems and by the early 1990s there were over half a million NetWare-based networks installed worldwide encompassing more than 50 million users. Novell technology contributed to the emergence of local area networks, which displaced the dominant mainframe computing model and changed computing worldwide. Novell became instrumental in making Utah Valley a focus for technology and software development.
SCO, The SCO Group, and The TSG Group are the various names of an American software company in existence from 2002 to 2012 that became known for owning Unix operating system assets that had belonged to the Santa Cruz Operation, including the UnixWare and OpenServer technologies, and then, under CEO Darl McBride, pursuing a series of high-profile legal battles known as the SCO-Linux controversies.
UnixWare is a Unix operating system. It was originally released by Univel, a jointly owned venture of AT&T's Unix System Laboratories (USL) and Novell. It was then taken over by Novell. Via Santa Cruz Operation (SCO), it went on to Caldera Systems, Caldera International, and The SCO Group before it was sold to UnXis. UnixWare is typically deployed as a server rather than a desktop. Binary distributions of UnixWare are available for x86 architecture computers. UnixWare is primarily marketed as a server operating system.
This is a list of operating systems specifically focused on security. Operating systems for general-purpose usage may be secure without having a specific focus on security.
SCO v. Novell was a United States lawsuit in which The SCO Group (SCO), a Linux and Unix vendor, claimed ownership of the source code for the Unix operating system, which they had separately alleged were infringed by the Linux operating system. SCO sought to have the court declare that SCO owned the rights to the Unix code, including the copyrights, and that Novell had committed slander of title by claiming those rights for itself.
SUSE Linux Enterprise is a Linux-based operating system developed by SUSE. It is available in two editions, suffixed with Server (SLES) for servers and mainframes, and Desktop (SLED) for workstations and desktop computers. Its major versions are released at an interval of 3–4 years, while minor versions are released about every 12 months. SUSE Linux Enterprise products receive more intense testing than the upstream openSUSE community product, with the intention that only mature, stable versions of the included components will make it through to the released enterprise product.
SUSE is a German-based multinational open-source software company that develops and sells Linux products to business customers. Founded in 1992, it was the first company to market Linux for enterprise. It is the developer of SUSE Linux Enterprise and the primary sponsor of the community-supported openSUSE Project, which develops the openSUSE Linux distribution. While the openSUSE "Tumbleweed" variation is an upstream distribution for both the "Leap" variation and SUSE Linux Enterprise distribution, its branded "Leap" variation is part of a direct upgrade path to the enterprise version, which effectively makes openSUSE Leap a non-commercial version of its enterprise product.
Caldera OpenLinux (COL) is a defunct Linux distribution. Caldera originally introduced it in 1997 based on the German LST Power Linux distribution, and then taken over and further developed by Caldera Systems since 1998. A successor to the Caldera Network Desktop put together by Caldera since 1995, OpenLinux was an early "business-oriented distribution" and foreshadowed the direction of developments that came to most other distributions and the Linux community generally.
AppArmor is a Linux kernel security module that allows the system administrator to restrict programs' capabilities with per-program profiles. Profiles can allow capabilities like network access, raw socket access, and the permission to read, write, or execute files on matching paths. AppArmor supplements the traditional Unix discretionary access control (DAC) model by providing mandatory access control (MAC). It has been partially included in the mainline Linux kernel since version 2.6.36 and its development has been supported by Canonical since 2009.
Linux Security Modules (LSM) is a framework allowing the Linux kernel to support without bias a variety of computer security models. LSM is licensed under the terms of the GNU General Public License and is a standard part of the Linux kernel since Linux 2.6. AppArmor, SELinux, Smack, and TOMOYO Linux are the currently approved security modules in the official kernel.
SUSE Linux is a computer operating system developed by SUSE. It is built on top of the free and open source Linux kernel and is distributed with system and application software from other open source projects. SUSE Linux is of German origin, its name being an acronym of "Software und System-Entwicklung", and it was mainly developed in Europe. The first version appeared in early 1994, making SUSE one of the oldest existing commercial distributions. It is known for its YaST configuration tool.
Novell Vibe is a web-based team collaboration platform developed by Novell, and was initially released by Novell in June 2008 under the name of Novell Teaming. Novell Vibe is a collaboration platform that can serve as a knowledge repository, document management system, project collaboration hub, process automation machine, corporate intranet or extranet. Users can upload, manage, comment on, and edit content in a secure manner. Supported content includes documents, calendars, discussion forums, wikis, blogs, tasks, and more.
Mono is a free and open-source .NET Framework-compatible software framework. Originally by Ximian, it was later acquired by Novell, and is now being led by Xamarin, a subsidiary of Microsoft and the .NET Foundation. Mono can be run on many software systems.
Linspire is a commercial operating system based on Debian and Ubuntu and currently owned by PC/OpenSystems LLC. It had been owned by Linspire. Inc. from 2001 to 2008, and then by Xandros from 2008 to 2017.
The Attachmate Group, Inc. was a privately held software holding company based in Houston, Texas in the United States. The major companies held by the group were Attachmate, NetIQ, Novell, and SUSE.
Microsoft, a technology company historically known for its opposition to the open source software paradigm, turned to embrace the approach in the 2010s. From the 1970s through 2000s under CEOs Bill Gates and Steve Ballmer, Microsoft viewed the community creation and sharing of communal code, later to be known as free and open source software, as a threat to its business, and both executives spoke negatively against it. In the 2010s, as the industry turned towards cloud, embedded, and mobile computing—technologies powered by open source advances—CEO Satya Nadella led Microsoft towards open source adoption although Microsoft's traditional Windows business continued to grow throughout this period generating revenues of 26.8 billion in the third quarter of 2018, while Microsoft's Azure cloud revenues nearly doubled.
