IBM 7950 Harvest
The IBM 7950, also known as Harvest, was a one-of-a-kind adjunct to the Stretch computer which was installed at the United States National Security Agency (NSA). Built by IBM, it was delivered in 1962 and operated until 1976, when it was decommissioned. Harvest was designed to be used for cryptanalysis. Development In April 1958, the final design for the NSA-customized version of IBM's Stretch computer had been approved, and the machine was installed in February 1962. The design engineer was James H. Pomerene, and it was built by IBM in Poughkeepsie, New York. Its electronics (fabricated of the same kind of discrete transistors used for Stretch) were physically about twice as big as the Stretch to which it was attached. Harvest added a small number of instructions to Stretch and could not operate independently. An evaluation conducted by the NSA found that Harvest was more powerful than the best commercially available machine by a factor of 50 to 200, depending on the task.Bam ...

HARVEST
Harvesting is the process of collecting plants, animals, or fish (as well as fungi) as food, especially the process of gathering mature crops, and "the harvest" also refers to the collected crops. Reaping is the cutting of grain or pulses for harvest, typically using a scythe, sickle, or reaper. On smaller farms with minimal mechanization, harvesting is the most labor-intensive activity of the growing season. On large mechanized farms, harvesting uses farm machinery, such as the combine harvester. Automation has increased the efficiency of both the seeding and harvesting processes. Specialized harvesting equipment, using conveyor belts for gentle gripping and mass transport, replaces the manual task of removing each seedling by hand. The term "harvesting" in general usage may include immediate postharvest handling, including cleaning, sorting, packing, and cooling. The completion of harvesting marks the end of the growing season, or the growing cycle for a particular c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compiler
In computing, a compiler is a computer program that Translator (computing), translates computer code written in one programming language (the ''source'' language) into another language (the ''target'' language). The name "compiler" is primarily used for programs that translate source code from a high-level programming language to a lower level language, low-level programming language (e.g. assembly language, object code, or machine code) to create an executable program.Compilers: Principles, Techniques, and Tools by Alfred V. Aho, Ravi Sethi, Jeffrey D. Ullman - Second Edition, 2007 There are many different types of compilers which produce output in different useful forms. A ''cross-compiler'' produces code for a different Central processing unit, CPU or operating system than the one on which the cross-compiler itself runs. A ''bootstrap compiler'' is often a temporary compiler, used for compiling a more permanent or better optimised compiler for a language. Related software ...

IBM 700/7000 Series
The IBM 700/7000 series is a series of large-scale (Mainframe computer, mainframe) computer systems that were made by IBM through the 1950s and early 1960s. The series includes several different, incompatible processor architectures. The 700s use vacuum-tube logic and were made obsolete by the introduction of the transistor computer, transistorized 7000s. The 7000s, in turn, were eventually replaced with IBM System/360, System/360, which was announced in 1964. However the 360/65, the first 360 powerful enough to replace 7000s, did not become available until November 1965. Early problems with OS/360 and the high cost of converting software kept many 7000s in service for years afterward. Architectures The IBM 700/7000 series has six completely different ways of storing data and instructions: *First scientific (36/18-bit words): IBM 701, 701 (Defense Calculator) *Later scientific (36-bit words, hardware Floating-point arithmetic, floating-point): IBM 704, 704, IBM 709, 709, IBM 70 ...

Samuel Simon Snyder
Samuel Simon Snyder (August 18, 1911 – December 28, 2007) was a cryptographer for the United States Government. His pioneering work in early computers led directly to the development of the computer as we know it, and laid the foundation for many aspects of the modern computing industry. He is known for having broken every Japanese encrypted message with his partners in the Signal Intelligence Service during World War II and for having developed the MARC standards. Career Snyder was an alumnus of George Washington University, where, at the height of the Great Depression, he attended night school, working on various government jobs during the day. While still at the university, Snyder started his career in 1934 with the Signal Intelligence Service as one of the first 10 employees,. He worked at the National Security Agency until 1964.

Cryptanalytic Computer
A cryptanalytic computer is a computer designed to be used for cryptanalysis, which nowadays involves massive statistical analysis and multiple trial decryptions that since before World War II are possible only with automated equipment. Polish cryptanalysts designed and built automated aids in their work on Enigma machine, Enigma traffic. Arguably, the first modern computer (digital, electronic, and somewhat programmable) was built for cryptanalytic work at Bletchley Park (the Colossus computer, Colossus) during the war. More modern computers were important after World War II, and some machines (like the Cray-1) are reported to have had machine instructions hardwired in at the request of NSA. Computers continue to be important in cryptanalysis well into the 21st century. NSA, in fact, is said to have the largest number of installed computers on the planet. Whether this is true in an age of Google computer farms and such is doubtful but remains publicly unknown. See also * Bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

BETA Programming Language
BETA is a pure object-oriented language originating within the "Scandinavian School" in object-orientation where the first object-oriented language Simula was developed.SourceOle Lehrmann Madsen: An overview of BETA Among its notable features, it introduced nested classes, and unified classes with procedures into so called patterns. It has been in development since 1976, with implementations known since 1986, by Kristen Nygaard together with Bent Bruun Kristensen, Ole Lehrmann Madsen, and Birger Møller-Pedersen, at the University of Oslo. The project is inactive as of October 2020. Features Technical overview From a technical perspective, BETA provides several unique features. Classes and Procedures are unified to one concept, a Pattern. Also, classes are defined as properties/attributes of objects. This means that a class cannot be instantiated without an explicit object context. A consequence of this is that BETA supports nested classes. Classes can be virtually defined, ...
