OpenServer
Xinuos OpenServer, previously SCO UNIX and SCO Open Desktop (SCO ODT), is a closed source computer operating system developed by Santa Cruz Operation (SCO), later acquired by SCO Group, and now owned by Xinuos. Early versions of OpenServer were based on UNIX System V, while the later OpenServer 10 is based on FreeBSD 10. History SCO UNIX/SCO Open Desktop SCO UNIX was the successor to the Santa Cruz Operation's variant of Microsoft Xenix, derived from UNIX System V Release 3.2 with an infusion of Xenix device drivers and utilities. SCO UNIX System V/386 Release 3.2.0 was released in 1989, as the commercial successor to SCO Xenix. The base operating system did not include TCP/IP networking or X Window System graphics; these were available as optional extra-cost add-on packages. Shortly after the release of this bare OS, SCO shipped an integrated product under the name of SCO Open Desktop, or ODT. 1994 saw the release of SCO MPX, an add-on SMP package. At the same time, AT&T com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SCO Group
The SCO Group (often referred to SCO and later called The TSG Group) was 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 (the original SCO), 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. The SCO Group began in 2002 with a renaming of Caldera International, accompanied by McBride becoming CEO and a major change in business strategy and direction. The SCO brand was re-emphasized and new releases of UnixWare and OpenServer came out. The company also attempted some initiatives in the e-commerce space with the SCOBiz and SCOx programs. In 2003, the SCO Group claimed that the increasingly popular free Linux operating system contained substantial amounts of Unix code that IBM had improperly put there. The SCOsource division was create ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santa Cruz Operation
The Santa Cruz Operation, Inc. (usually known as SCO, pronounced either as individual letters or as a word) was an American software company, based in Santa Cruz, California, that was best known for selling three Unix operating system variants for Intel x86 processors: Xenix, SCO UNIX (later known as SCO OpenDesktop and SCO OpenServer), and UnixWare. SCO was founded in 1979 by Larry Michels and his son Doug Michels and began as a consulting and Unix porting company. An early involvement with Microsoft led to SCO making a product out of Xenix on Intel-based PCs. The fundamental insight that led to SCO's success was that there was a large market for a standard, "open systems" operating system on commodity microprocessor hardware that would give business applications computing power and throughput that previously was only possible with considerably more expensive minicomputers. SCO built a large community of value-added resellers that would eventually become 15,000 stro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xinuos
Xinuos is an American software company that was created in 2011 and was first called UnXis until assuming its current name in 2013. (Both names have been variations on the spelling of the Unix operating system.) Xinuos develops and markets the Unix-based OpenServer 6, OpenServer 5, and UnixWare 7 operating systems under SCO branding, as well as the newer OpenServer 10 operating system. Background The SCO Group (SCO) was a Utah-based software company that had over time acquired the operating system products SCO OpenServer and UnixWare, which dated back to earlier companies The Santa Cruz Operation and Unix System Laboratories and to the early history of Unix before that. But by the late 1990s these products found themselves losing in the marketplace, first to Microsoft's Windows NT and Windows Server line and then to open source Linux. Beginning in 2003, the SCO Group began issuing proclamations and lawsuits, including ''SCO v. IBM'', based upon a belief that SCO Unix in ...

Caldera Systems
Caldera International, Inc., earlier Caldera Systems, was an American software company that existed from 1998 to 2002 and developed and sold Linux- and Unix-based operating system products. Caldera Systems was created in August 1998 as a spinoff of Caldera, Inc., with Ransom Love as its CEO. It focused on selling Caldera OpenLinux, a high-end Linux distribution aimed at business customers that included features it developed, such as an easy-to-use, graphical installer and graphical and web-based system administration tools, as well as features from bundled proprietary software. Caldera Systems was also active in the Java (software platform), Java language and software platform on Linux community. In March 2000, Caldera Systems staged a successful initial public offering, IPO of its stock, although the stock price did not reach the stratospheric heights of its chief competitor Red Hat and some other companies during the "Linux mania" of 1999. In August 2000, Caldera Systems anno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UNIX System V
Unix System V (pronounced: "System Five") is one of the first commercial versions of the Unix operating system. It was originally developed by AT&T and first released in 1983. Four major versions of System V were released, numbered 1, 2, 3, and 4. System V Release 4 (SVR4) was commercially the most successful version, being the result of an effort, marketed as ''Unix System Unification'', which solicited the collaboration of the major Unix vendors. It was the source of several common commercial Unix features. System V is sometimes abbreviated to SysV. , the AT&T-derived Unix market is divided between four System V variants: IBM's AIX, Hewlett Packard Enterprise's HP-UX and Oracle's Solaris, plus the free-software illumos forked from OpenSolaris. Overview Introduction System V was the successor to 1982's UNIX System III. While AT&T developed and sold hardware that ran System V, most customers ran a version from a reseller, based on AT&T's reference implementation ...

Xenix
Xenix is a discontinued version of the Unix operating system for various microcomputer platforms, licensed by Microsoft from AT&T Corporation in the late 1970s. The Santa Cruz Operation (SCO) later acquired exclusive rights to the software, and eventually replaced it with SCO UNIX (now known as SCO OpenServer). In the mid-to-late 1980s, Xenix was the most common Unix variant, measured according to the number of machines on which it was installed. Microsoft chairman Bill Gates said at Unix Expo in 1996 that, for a long time, Microsoft had the highest-volume AT&T Unix license. History Bell Labs, the developer of Unix, was part of the regulated Bell System and could not sell Unix directly to most end users (academic and research institutions excepted); it could, however, license it to software vendors who would then resell it to end users (or their own resellers), combined with their own added features. Microsoft, which expected that Unix would be its operating system of the fut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
POSIX
The Portable Operating System Interface (POSIX) is a family of standards specified by the IEEE Computer Society for maintaining compatibility between operating systems. POSIX defines both the system- and user-level application programming interfaces (APIs), along with command line shells and utility interfaces, for software compatibility (portability) with variants of Unix and other operating systems. POSIX is also a trademark of the IEEE. POSIX is intended to be used by both application and system developers. Name Originally, the name "POSIX" referred to IEEE Std 1003.1-1988, released in 1988. The family of POSIX standards is formally designated as IEEE 1003 and the ISO/IEC standard number is ISO/ IEC 9945. The standards emerged from a project that began in 1984 building on work from related activity in the ''/usr/group'' association. Richard Stallman suggested the name ''POSIX'' (pronounced as ''pahz-icks,'' as in ''positive'', not as ''poh-six'') to the IEEE instead of f ...
