Vesta (software Configuration Management)
Vesta is a software configuration management system developed in the 1990s. History Vesta was developed by researchers at the Digital Equipment Corporation (DEC) Systems Research Center in Palo Alto, California. The language for Vesta was first published in 1993. Vesta's approach to incremental software building was to give the user a language to describe how to build the software, and let the builder infer dependencies, unlike other systems where the user specifies the dependencies explicitly. A redesign and reimplementation called Vesta-2 was begun around 1998. Vesta was released by Compaq after it acquired DEC, under the GNU Lesser General Public License (LGPL) in 2001. Vesta features include: * A guarantee of precise build repeatability. Vesta builds are encapsulated in an environment cut off from the normal filesystem. They cannot use any files, settings, or other inputs that aren't under revision control. * Completely automatic dependency detection. The Vesta builder reco ...

Software Configuration Management
Software configuration management (SCM), a.k.a. software change and configuration management (SCCM), is the software engineering practice of tracking and controlling changes to a software system; part of the larger cross-disciplinary field of configuration management (CM). SCM includes version control and the establishment of baselines. Goals The goals of SCM include: * Configuration identification - Identifying configurations, configuration items and baselines. * Configuration control - Implementing a controlled change process. This is usually achieved by setting up a change control board whose primary function is to approve or reject all change requests that are sent against any baseline. * Configuration status accounting - Recording and reporting all the necessary information on the status of the development process. * Configuration auditing - Ensuring that configurations contain all their intended parts and are sound with respect to their specifying documents, inclu ...

Digital Equipment Corporation
Digital Equipment Corporation (DEC ), using the trademark Digital, was a major American company in the computer industry from the 1960s to the 1990s. The company was co-founded by Ken Olsen and Harlan Anderson in 1957. Olsen was president until he was forced to resign in 1992, after the company had gone into precipitous decline. The company produced many different product lines over its history. It is best known for the work in the minicomputer market starting in the early 1960s. The company produced a series of machines known as the Programmed Data Processor, PDP line, with the PDP-8 and PDP-11 being among the most successful minis in history. Their success was only surpassed by another DEC product, the late-1970s VAX "supermini" systems that were designed to replace the PDP-11. Although a number of competitors had successfully competed with Digital through the 1970s, the VAX cemented the company's place as a leading vendor in the computer space. As microcomputers improved in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DEC Systems Research Center
The Systems Research Center (SRC) was a research laboratory created by Digital Equipment Corporation (DEC) in 1984, in Palo Alto, California. DEC SRC was founded by a group of computer scientists, led by Robert Taylor, who left the Computer Science Laboratory (CSL) of Xerox PARC after an internal power struggle. SRC survived the takeover of DEC by Compaq in 1998. It was renamed to "Compaq Systems Research Center". When Compaq was acquired by Hewlett-Packard in 2002, SRC was merged with other HP corporate research labs and relocated there. After Taylor's retirement, the lab was directed by Roy Levin and then by Lyle Ramshaw. Some of the critical developments made at SRC include the Modula-3 programming language; the snoopy cache, used in the first multiprocessor workstation, the Firefly, built from MicroVAX 78032 microprocessors; the first multi-threaded Unix system, Taos; the first user interface editor; early networked window systems, Trestle. AltaVista was jointly deve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palo Alto, California
Palo Alto ( ; Spanish language, Spanish for ) is a charter city in northwestern Santa Clara County, California, United States, in the San Francisco Bay Area, named after a Sequoia sempervirens, coastal redwood tree known as El Palo Alto. The city of Palo Alto was incorporated in 1894 by the American industrialist Leland Stanford and his wife, Jane Stanford, when they founded Stanford University in memory of their only child, Leland Stanford Jr. Palo Alto later expanded and now borders East Palo Alto, California, East Palo Alto, Mountain View, California, Mountain View, Los Altos, California, Los Altos, Los Altos Hills, California, Los Altos Hills, Stanford, California, Stanford, Portola Valley, California, Portola Valley, and Menlo Park, California, Menlo Park.

Programming Language
A programming language is a system of notation for writing computer programs. Programming languages are described in terms of their Syntax (programming languages), syntax (form) and semantics (computer science), semantics (meaning), usually defined by a formal language. Languages usually provide features such as a type system, Variable (computer science), variables, and mechanisms for Exception handling (programming), error handling. An Programming language implementation, implementation of a programming language is required in order to Execution (computing), execute programs, namely an Interpreter (computing), interpreter or a compiler. An interpreter directly executes the source code, while a compiler produces an executable program. Computer architecture has strongly influenced the design of programming languages, with the most common type (imperative languages—which implement operations in a specified order) developed to perform well on the popular von Neumann architecture. ...

Compaq
Compaq Computer Corporation was an American information technology, information technology company founded in 1982 that developed, sold, and supported computers and related products and services. Compaq produced some of the first IBM PC compatible computers, being the second company after Columbia Data Products to legally Reverse engineering, reverse engineer the BIOS of the IBM Personal Computer. It rose to become the Market share of personal computer vendors, largest supplier of PC systems during the 1990s. The company was initially based in Harris County, Texas. The company was formed by Rod Canion, Jim Harris (entrepreneur), Jim Harris, and Bill Murto, all of whom were former Texas Instruments senior managers.

GNU Lesser General Public License
The GNU Lesser General Public License (LGPL) is a free-software license published by the Free Software Foundation (FSF). The license allows developers and companies to use and integrate a software component released under the LGPL into their own (even proprietary) software without being required by the terms of a strong copyleft license to release the source code of their own components. However, any developer who modifies an LGPL-covered component is required to make their modified version available under the same LGPL license. For proprietary software, code under the LGPL is usually used in the form of a shared library, so that there is a clear separation between the proprietary and LGPL components. The LGPL is primarily used for software libraries, although it is also used by some stand-alone applications. The LGPL was developed as a compromise between the strong copyleft of the GNU General Public License (GPL) and more permissive licenses such as the BSD licenses and the MI ...

Make (software)
In software development, Make is a command-line interface software tool that performs actions ordered by configured dependencies as defined in a configuration file called a ''makefile''. It is commonly used for build automation to build executable code (such as a program or library) from source code. But, not limited to building, Make can perform any operation available via the operating system shell. Make is widely used, especially in Unix and Unix-like operating systems, even though many competing technologies and tools are available, including similar tools that perform actions based on dependencies, some compilers and interactively via an integrated development environment. In addition to referring to the original Unix tool, Make is also a technology since multiple tools have been implemented with roughly the same functionality including similar makefile syntax and semantics. Origin Stuart Feldman created Make while at Bell Labs. An early version was completed in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
