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, which was purchased by IBM International Business Machines Corporation (using the trademark IBM), nicknamed Big Blue, is an American Multinational corporation, multinational technology company headquartered in Armonk, New York, and present in over 175 countries.

ClearCase
IBM DevOps Code ClearCase (also known as IBM 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 customized to support a wide variety of needs. ClearCase can accommodate large binary files, a large number of files, and large repository sizes. It supports branching and labeling. It enables the correc ...

Apollo Domain
Apollo/Domain is a series of workstations that were developed and produced by Apollo Computer from to 1989. The machines were built around the Motorola 68k series of processors, except for the DN10000, which has from one to four of Apollo's RISC processors, named PRISM. Operating system The original operating system is Apollo's own product called Aegis, which was later renamed to Domain/OS. The Aegis and Domain/OS system offers 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 resembles a modern PC, with a base unit, keyboard, mouse, and screen. Early models are housed in short (about 2 feet high) 19" rack cabinets to be set beside a desk or under a table. The DN300 and later DN330 were designed as integrated units with the system and monitor in one unit. These models fit easily on ...

Apollo Computer
Apollo Computer Inc. was an American technology corporation headquartered and founded in Chelmsford, Massachusetts. It was founded in 1980 by William Poduska (a founder of Prime Computer) and others. Apollo Computer 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. Like other computer companies at the time, 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 rival Sun Microsystems. In addition to Poduska, the founders included Dave Nelson (engineering), Mike Greata (engineering), Charlie Spector (COO), Bob Antonuccio (manufacturing), Gerry St ...

Hewlett-Packard
The Hewlett-Packard Company, commonly shortened to Hewlett-Packard ( ) or HP, was an American multinational information technology company. It was founded by Bill Hewlett and David Packard in 1939 in a one-car garage in Palo Alto, California, where the company would remain headquartered for the remainder of its lifetime; this HP Garage is now a designated landmark and marked with a plaque calling it the "Birthplace of 'Silicon Valley. HP developed and provided a wide variety of hardware components, as well as software and related services, to consumers, small and medium-sized businesses (small and medium-sized enterprises, SMBs), and fairly large companies, including customers in government sectors, until the company officially split into Hewlett Packard Enterprise and HP Inc. in 2015. HP initially produced a line of electronic test and measurement equipment. It won its first big contract in 1938 to provide the HP 200B, a variation of its first product, the HP 200A low-distor ...

Software consists of computer programs that instruct the execution of a computer. Software also includes design documents and specifications. The history of software is closely tied to the development of digital computers in the mid-20th century. Early programs were written in the machine language specific to the hardware. The introduction of high-level programming languages in 1958 allowed for more human-readable instructions, making software development easier and more portable across different computer architectures. Software in a programming language is run through a compiler or interpreter to execute on the architecture's hardware. Over time, software has become complex, owing to developments in networking, operating systems, and databases. Software can generally be categorized into two main types: # operating systems, which manage hardware resources and provide services for applications # application software, which performs specific tasks for users The rise of cloud ...
