Atria Software
Atria Software Inc. was a software company that developed ClearCase in the early 1990s. It was founded by David B Leblang, Paul Levine, David Jabs and others on January 11, 1990. Some of the Atria developers had worked on an earlier system: ''DSEE'' (Domain Software Engineering Environment) from Apollo Computer. After Hewlett-Packard bought Apollo Computer in 1989, they left to form Atria. Atria later merged with Pure Software to form Pure Atria. That firm merged with Rational Software Rational Machines is an enterprise founded by Paul Levy and Mike Devlin in 1981 to provide tools to expand the use of modern software engineering practices, particularly explicit modular architecture and iterative development. It changed its ..., which was purchased by IBM in 2003. IBM continues to develop and market ClearCase.

ClearCase
Rational ClearCase is a family of computer software tools that supports software configuration management (SCM) of source code and other software development assets. It also supports design-data management of electronic design artifacts, thus enabling hardware and software co-development. ClearCase includes revision control and forms the basis for configuration management at large and medium-sized businesses, accommodating projects with hundreds or thousands of developers. It is developed by IBM. ClearCase supports two configuration management models: UCM (Unified Change Management) and base ClearCase. UCM provides an out-of-the-box model while base ClearCase provides a basic infrastructure (UCM is built on base ClearCase). Both can be configured to support a wide variety of needs. ClearCase can accommodate large binary files, large numbers of files, and large repository sizes. It supports branching, labeling, and versioning of directories. It uses the MultiVersion File System ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apollo Domain
Apollo/Domain was a range of workstations developed and produced by Apollo Computer from circa 1980 to 1989. The machines were built around the Motorola 68k family of processors, except for the DN10000, which had from one to four of Apollo's RISC processors, named PRISM. Operating system The original operating system was Apollo's own product called Aegis, which was later renamed to Domain/OS. The Aegis and Domain/OS system offered advanced features for the time, for example an object oriented filesystem, network transparency, diskless booting, a graphical user interface and, in Domain/OS, interoperability with BSD, System V and POSIX. Hardware An Apollo workstation resembled a modern PC, with base unit, keyboard, mouse, and screen. Early models were housed in short (about 2 ft high) 19" rack cabinets that would be set beside a desk or under a table. The DN300 and later DN330 were designed as integrated units with system and monitor in one unit and fit easily on a desk. Eve ...

Apollo Computer
Apollo Computer Inc., founded in 1980 in Chelmsford, Massachusetts, by William Poduska (a founder of Prime Computer) and others, developed and produced Apollo/Domain workstations in the 1980s. Along with Symbolics and Sun Microsystems, Apollo was one of the first vendors of graphical workstations in the 1980s. Like computer companies at the time and unlike manufacturers of IBM PC compatibles, Apollo produced much of its own hardware and software. Apollo was acquired by Hewlett-Packard in 1989 for US$476 million (equivalent to $ million in ), and gradually closed down over the period of 1990–1997. The brand (as "HP Apollo") was resurrected in 2014 as part of HP's high-performance computing portfolio. History Apollo was started in 1980, two years before Sun Microsystems. In addition to Poduska, the founders included Dave Nelson (Engineering), Mike Greata (Engineering), Charlie Spector (COO), Bob Antonuccio (Manufacturing), Gerry Stanley (Sales and Marketing), and Dave Lub ...

Hewlett-Packard
The Hewlett-Packard Company, commonly shortened to Hewlett-Packard ( ) or HP, was an American multinational information technology company headquartered in Palo Alto, California. HP developed and provided a wide variety of hardware components, as well as software and related services to consumers, small and medium-sized businesses ( SMBs), and large enterprises, including customers in the government, health, and education sectors. The company was founded in a one-car garage in Palo Alto by Bill Hewlett and David Packard in 1939, and initially produced a line of electronic test and measurement equipment. The HP Garage at 367 Addison Avenue is now designated an official California Historical Landmark, and is marked with a plaque calling it the "Birthplace of 'Silicon Valley'". The company won its first big contract in 1938 to provide test and measurement instruments for Walt Disney's production of the animated film ''Fantasia'', which allowed Hewlett and Packard to formally esta ...

Pure Software
Pure Software was founded in October 1991 by Reed Hastings, Raymond Peck and Mark Box. The original product was a debugging tool for Unix/C engineers called Purify. After adding new products such as Quantify and PureLink, and doubling its revenue every year for four years, Pure Software went public with the help of Morgan Stanley in August 1995. In August 1996, Pure Software merged with Atria Software to form ''Pure Atria Corporation''. Later in August 1997, Rational Software acquired Pure Atria, giving Hastings the capital to start Netflix. When Pure Atria was acquired by Rational Software, it triggered a 42% drop in both companies' stocks after the deal was announced. Hastings was appointed Chief Technical Officer of the combined companiesWall Street Journal. "Investors Pan Rational's Plan To Buy Pure Atria for Stock" by Don Clark.

Software is a set of computer programs and associated software documentation, documentation and data (computing), data. This is in contrast to Computer hardware, hardware, from which the system is built and which actually performs the work. At the low level language, lowest programming level, executable code consists of Machine code, machine language instructions supported by an individual Microprocessor, processor—typically a central processing unit (CPU) or a graphics processing unit (GPU). Machine language consists of groups of Binary number, binary values signifying Instruction set architecture, processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction System call, may also invoke one of many Input/output, input or output operations, for example displaying some text on ...
