Leonard H. Tower Jr.
Leonard "Len" H. Tower Jr. (born June 17, 1949) is a free software activist and one of the founding board members of the Free Software Foundation, where he contributed to the initial releases of gcc and GNU diff. He left the Free Software Foundation in 1997. Birth Tower was born June 17, 1949 in Astoria, Queens in New York City, U.S. Academic career In 1971, Tower received an SB in biology from the Massachusetts Institute of Technology. During that time he was Business Manager at '' The Tech'', the student newspaper. GNU project As the FSF's first full-time paid employee, Tower mostly performed administrative tasks including managing mailing lists, newsgroups and requests for information. In 1986, Tower assisted Richard Stallman with Stallman's initial plan to base the C compiler for the GNU Project on the Pastel compiler Stallman had obtained from Lawrence Livermore Lab. Tower worked on rewriting the existing code from Pastel, a variation of Pascal, into C while ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
League For Programming Freedom
League for Programming Freedom (LPF) was founded in 1989 by Richard Stallman to unite free software developers as well as developers of proprietary software to fight against software patents and the extension of the scope of copyright. Their logo is the Statue of Liberty holding a floppy disk and tape spool. Among other initiatives, the League started the "Burn all GIFs" campaign in opposition to the actions of Unisys in enforcing their patent on LZW compression used by CompuServe when creating the image format. The League produced a newsletter, ''Programming Freedom'', in 11 issues from 1991 to 1995. These primary source materials chronicle the work of the organization. The single event that had the most influence on the creation of the League was Apple's lawsuits against Microsoft about supposed copyrights violations of the look and feel of the Macintosh in the development of Windows. After the lawsuit ended, the League went dormant, to be resurrected by those who were i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pastel (programming Language)
Pastel is an extended version of the Pascal programming language, created in c. 1982 for ''Amber'', an operating system for the S-1 supercomputer project at Lawrence Livermore National Laboratory in California. The Pastel compiler was the inspiration for Richard Stallman's GNU C compiler. Pastel was conceived by Jeffrey M. Broughton, then Project Engineer in charge of compilers and operating system software for the S-1 project, because of dissatisfaction with the PL/1 PL/I (Programming Language One, pronounced and sometimes written PL/1) is a procedural, imperative computer programming language developed and published by IBM. It is designed for scientific, engineering, business and system programming. I ... language in which Amber was being implemented. The language was named Pastel ("an off-color Pascal"). Compared with Pascal compilers of that period, Pastel's features included: Chapter: S-l Software Development: Programming Languages Supported *Improved type definition ...

People From Queens, New York
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

GNU People
GNU () is an extensive collection of free software (383 packages as of January 2022), which can be used as an operating system or can be used in parts with other operating systems. The use of the completed GNU tools led to the family of operating systems popularly known as Linux. Most of GNU is licensed under the GNU Project's own General Public License (GPL). GNU is also the project within which the free software concept originated. Richard Stallman, the founder of the project, views GNU as a "technical means to a social end". Relatedly, Lawrence Lessig states in his introduction to the second edition of Stallman's book ''Free Software, Free Society'' that in it Stallman has written about "the social aspects of software and how Free Software can create community and social justice". Name ''GNU'' is a recursive acronym for "GNU's Not Unix!", chosen because GNU's design is Unix-like, but differs from Unix by being free software and containing no Unix code. Stallman chose th ...

Register Transfer Language
In computer science, register transfer language (RTL) is a kind of intermediate representation (IR) that is very close to assembly language, such as that which is used in a compiler. It is used to describe data flow at the register-transfer level of an architecture. Academic papers and textbooks often use a form of RTL as an architecture-neutral assembly language. RTL is used as the name of a specific intermediate representation in several compilers, including the GNU Compiler Collection (GCC), Zephyr, and the European compiler projects CerCo and CompCert. History The idea behind RTL was first described in ''The Design and Application of a Retargetable Peephole Optimizer''. GCC In GCC, RTL is generated from the GIMPLE representation, transformed by various passes in the GCC middle-end, and then converted to assembly language. GCC's RTL is usually written in a form which looks like a Lisp S-expression In computer programming, an S-expression (or symbolic expression, abbrev ...

Pascal (programming Language)
Pascal is an imperative and procedural programming language, designed by Niklaus Wirth as a small, efficient language intended to encourage good programming practices using structured programming and data structuring. It is named in honour of the French mathematician, philosopher and physicist Blaise Pascal. Pascal was developed on the pattern of the ALGOL 60 language. Wirth was involved in the process to improve the language as part of the ALGOL X efforts and proposed a version named ALGOL W. This was not accepted, and the ALGOL X process bogged down. In 1968, Wirth decided to abandon the ALGOL X process and further improve ALGOL W, releasing this as Pascal in 1970. On top of ALGOL's scalars and arrays, Pascal enables defining complex datatypes and building dynamic and recursive data structures such as lists, trees and graphs. Pascal has strong typing on all objects, which means that one type of data cannot be converted to or interpreted as another without explicit conversi ...
