The Evolution of Lisp
1 The Evolution of Lisp Guy L. Steele Jr. Richard P. Gabriel Thinking Machines Corporation Lucid, Inc. 245 First Street 707 Laurel Street Cambridge, Massachusetts 02142 Menlo Park, California 94025 Phone: (617) 234-2860 Phone: (415) 329-8400 FAX: (617) 243-4444 FAX: (415) 329-8480 E-mail: [email protected] E-mail: [email protected] Abstract Lisp is the world’s greatest programming language—or so its proponents think. The structure of Lisp makes it easy to extend the language or even to implement entirely new dialects without starting from scratch. Overall, the evolution of Lisp has been guided more by institutional rivalry, one-upsmanship, and the glee born of technical cleverness that is characteristic of the “hacker culture” than by sober assessments of technical requirements. Nevertheless this process has eventually produced both an industrial- strength programming language, messy but powerful, and a technically pure dialect, small but powerful, that is suitable for use by programming-language theoreticians. We pick up where McCarthy’s paper in the first HOPL conference left off. We trace the development chronologically from the era of the PDP-6, through the heyday of Interlisp and MacLisp, past the ascension and decline of special purpose Lisp machines, to the present era of standardization activities. We then examine the technical evolution of a few representative language features, including both some notable successes and some notable failures, that illuminate design issues that distinguish Lisp from other programming languages. We also discuss the use of Lisp as a laboratory for designing other programming languages. We conclude with some reflections on the forces that have driven the evolution of Lisp. -
Storage Organization and Management in TENEX I. Introduction
Storage Organization and Management in TENEX http://www.linique.com/dlm/tenex/fjcc72/ Storage Organization and Management in TENEX by Daniel L. Murphy Presented at the Fall Joint Computer Conference, 1972. Originally published in AFIPS Conference Proceedings Volume 41. I. Introduction In early 1969, BBN began an effort aimed at developing a new time-shared operating system. It was felt at the time that none of the commercially available systems could meet the needs of the research planned and in progress at BBN. The foremost requirement of the desired operating system was that it support a directly addressed process memory in which large list-processing computations could be performed. The cost of core storage prohibited the acquisition of sufficient memory for even one such process, and the problems of swapping such very large processes in a time-sharing environment made that solution technically infeasible as well. Paging was therefore the logical alternative, and our study and experience with list processing systems(1,2) led us to believe that using a demand-paged virtual memory system for such computations was a feasible approach. With demand paged process virtual memory added to our requirements, we found no existing system which could adequately meet our needs. Our approach was to take an existing system which was otherwise appropriate and add the necesary hardware to support paging. The system chosen was the DEC PDP-10 (3), which, although not paged, was available with a time-shared operating system and substantial support software. Consideration was given to modifying the existing PDP-10 operating system to support demand paging, but that approach was rejected because of the substantial amount of work which would be required, because of the inherent constraints imbedded in the architecture of any large system, and because development of a new operating system would allow the inclusion of a great many other features and facilities which were judged desirable. -

Dejan Grba SELECTED FILMOGRAPHY OF DIGITAL CULTURE AND NEW MEDIA ART This filmography comprises feature films, documentaries, TV shows, series and reports about digital culture and new media art. The selected feature films reflect the informatization of society, economy and politics in various ways, primarily on the conceptual and narrative plan. Feature films that directly thematize the digital paradigm can be found in the Film Lists section. Each entry is referenced with basic filmographic data: director’s name, title and production year, and production details are available online at IMDB, FilmWeb, FindAnyFilm, Metacritic etc. The coloured titles are links.

NWG/RFC# 752 MRC 2-Jan-79 01:22 Nnnnn a Universal Host Table
NWG/RFC# 752 MRC 2-Jan-79 01:22 nnnnn A Universal Host Table Network Working Group Mark Crispin Request for Comments 752 SU-AI NIC nnnnn 2 January 1979 A Universal Host Table ABSTRACT: The network host table in use at MIT and Stanford is described. This host table is superior to the NIC and Tenex host tables in several ways. A binary file, compiled from this host table, is also described. This file is used by subsystems on MIT's ITS and Stanford's WAITS timesharing systems for efficiency in host and network lookups. HISTORY: As with many other sites on the Arpanet, we found the NIC's host table unsuited to our needs. Part of the problem was because the NIC host table was often inaccurate and all too often failed to include several nicknames in common usage in our communities. In addition, the NIC host table's format was awkward for user programs to use, especially those which wanted to have the host table mapped into memory in some sort of structured binary form for efficient lookups. Finally, the NIC host table neglects to include some essential information. The ITS host table was originally designed to be compiled along with a network handling program (MIDAS, the PDP-10 assembler used, has a pseudo-op to insert a file into an assembly). In order to make the host table palatable to the assembler, every comment line began with a semicolon, and every actual data line began with the word HOST. Each program which used the host table defined HOST as an assembly macro before inserting the host table into the assembly. -
