Plan 9 From User Space
Plan 9 from User Space (also plan9port or p9p) is a port of many Plan 9 from Bell Labs libraries and applications to Unix-like operating systems. Currently it has been tested on a variety of operating systems including: Linux, macOS, FreeBSD, NetBSD, OpenBSD, Solaris and SunOS. The project's name is a reference to the 1950s Ed Wood film '' Plan 9 from Outer Space''. A number of key applications have been ported, as have programs used by the system itself, along with the requisite libraries from Plan 9. All of these have been made to work on top of a Unix-like environment instead of their native Plan 9. Some of the most significant ported components are: * rc – The Plan 9 shell. * sam – A text editor. * acme – A combination text editor and graphical shell especially useful to programmers. * mk – A tool for building software, analogous to the traditional Unix make utility. * plumber – An interprocess messaging facility. * Venti Venti is a network storage system that ...

ANSI C
ANSI C, ISO C, and Standard C are successive standards for the C programming language published by the American National Standards Institute (ANSI) and ISO/IEC JTC 1/SC 22/WG 14 of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). Historically, the names referred specifically to the original and best-supported version of the standard (known as C89 or C90). Software developers writing in C are encouraged to conform to the standards, as doing so helps portability between compilers. History and outlook The first standard for C was published by ANSI. Although this document was subsequently adopted by ISO/IEC and subsequent revisions published by ISO/IEC have been adopted by ANSI, "ANSI C" is still used to refer to the standard. While some software developers use the term ISO C, others are standards-body neutral and use Standard C. Standardizing C In 1983, the American National Standards Institute formed a committee, ...

Ed Wood
Edward Davis Wood Jr. (October 10, 1924 – December 10, 1978) was an American filmmaker, actor, and pulp novel author. In the 1950s, Wood directed several low-budget science fiction, crime and horror films that later became cult classics, notably ''Glen or Glenda'' (1953), '' Jail Bait'' (1954), '' Bride of the Monster'' (1955), '' Plan 9 from Outer Space'' (1957)Rudolph Grey, Nightmare of Ecstasy: The Life and Art of Edward D. Wood, Jr. (1992). pg. 197. ISBN 978-0-922915-24-8. and '' Night of the Ghouls'' (1959). In the 1960s and 1970s, he moved towards sexploitation and pornographic films such as '' The Sinister Urge'' (1960), '' Orgy of the Dead'' (1965) and '' Necromania'' (1971), and wrote over 80 lurid pulp crime and sex novels. Notable for their campy aesthetics, technical errors, unsophisticated special effects, use of poorly-matched stock footage, eccentric casts, idiosyncratic stories and non sequitur dialogue, Wood's films remained largely obscure unt ...

Venti
Venti is a network storage system that permanently stores data blocks. A 160-bit SHA-1 hash of the data (called ''score'' by Venti) acts as the address of the data. This enforces a ''write-once'' policy since no other data block can be found with the same address: the addresses of multiple writes of the same data are identical, so duplicate data is easily identified and the data block is stored only once. Data blocks cannot be removed, making it ideal for permanent or backup storage. Venti is typically used with Fossil to provide a file system with permanent snapshots. History Venti was designed and implemented by Sean Quinlan and Sean Dorward at Bell Labs. It appeared in the Plan 9 distribution in 2002. Development has been continued by Russ Cox who has reimplemented most of the server, written a library for creating datastructures (files, directories and meta-data) to store in Venti and implemented optimizations. Venti is available both in the Plan 9 distribution and f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plumber (Plan 9)
The plumber, in the Plan 9 from Bell Labs and Inferno operating systems, is a mechanism for reliable uni- or multicast inter-process communication of formatted textual messages. It uses the Plan 9 network file protocol, 9P, rather than a special-purpose IPC mechanism. Any number of clients may listen on a named port (a file) for messages. Ports and port routing are defined by plumbing rules. These rules are dynamic. Each listening program receives a copy of matching messages. For example, if the data /sys/lib/plumb/basic is plumbed with the standard rules, it is sent to the edit port. The port will write a copy of the message to each listener. In this case, all running editors will interpret this message as a file name, and open the file. The plumber is the 9P file server that provides this service. Clients may use libplumb to format messages. Since the messages are 9P, they are network transparent. See also * Pipeline (software) External links * * * *"Plumbing and ...

Make (software)
In software development, Make is a build automation tool that automatically builds executable programs and libraries from source code by reading files called ''Makefiles'' which specify how to derive the target program. Though integrated development environments and language-specific compiler features can also be used to manage a build process, Make remains widely used, especially in Unix and Unix-like operating systems. Besides building programs, Make can be used to manage any project where some files must be updated automatically from others whenever the others change. Origin There are now a number of dependency-tracking build utilities, but Make is one of the most widespread, primarily due to its inclusion in Unix, starting with the PWB/UNIX 1.0, which featured a variety of tools targeting software development tasks. It was originally created by Stuart Feldman in April 1976 at Bell Labs. Feldman received the 2003 ACM Software System Award for the authoring of this widesprea ...

Shell (computing)
In computing, a shell is a computer program that exposes an operating system's services to a human user or other programs. In general, operating system shells use either a command-line interface (CLI) or graphical user interface (GUI), depending on a computer's role and particular operation. It is named a shell because it is the outermost layer around the operating system. Command-line shells require the user to be familiar with commands and their calling syntax, and to understand concepts about the shell-specific scripting language (for example, bash), while graphical shells place a low burden on beginning computer users and are characterized as being easy to use, yet most GUI-enabled operating systems also provide CLI shells, normally for performing advanced tasks. Overview Operating systems provide various services to their users, including file management, process management (running and terminating applications), batch processing, and operating system monitoring and con ...

Text Editor
A text editor is a type of computer program that edits plain text. Such programs are sometimes known as "notepad" software (e.g. Windows Notepad). Text editors are provided with operating systems and software development packages, and can be used to change files such as configuration files, documentation files and programming language source code. Plain text and rich text There are important differences between plain text (created and edited by text editors) and rich text (such as that created by word processors or desktop publishing software). Plain text exclusively consists of character representation. Each character is represented by a fixed-length sequence of one, two, or four bytes, or as a variable-length sequence of one to four bytes, in accordance to specific character encoding conventions, such as ASCII, ISO/IEC 2022, Shift JIS, UTF-8, or UTF-16. These conventions define many printable characters, but also non-printing characters that control the flow of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acme (text Editor)
Acme is a text editor and graphical shell from the Plan 9 from Bell Labs operating system, designed and implemented by Rob Pike. It can use the Sam command language. The design of the interface was influenced by Oberon. It is different from other editing environments in that it acts as a 9P server. A distinctive element of the user interface is mouse chording. Overview Acme can be used as a mail and news reader, or as a frontend to wikifs. These applications are made possible by external components interacting with acme through its file system interface. Rob Pike has mentioned that the name "Acme" was suggested to him by Penn Jillette of Penn & Teller during a movie night at Times Square when he asked for a suitable name for a text editor that does "everything". Ports A port to the Inferno operating system is part of Inferno's default distribution. Inferno can run as an application on top of other operating systems, allowing Inferno's port of acme to be used on most operati ...

Sam (text Editor)
Sam is a multi-file text editor based on structural regular expressions. It was originally designed in the early 1980s at Bell Labs by Rob Pike with the help of Ken Thompson and other Unix developers for the Blit windowing terminal running on Unix; it was later ported to other systems. Sam follows a classical modular Unix aesthetic. It is internally simple, its power leveraged by the composability of a small command language and extensibility through shell integration. Design and features Sam is designed as two synchronous programs: a command interpreter and a mouse-oriented bitmap windowing interface. The interpreter's command set is modeled after the UNIX editor ed and may be used to operate the editor from a standard text terminal. By default, however, Sam presents its own graphical user interface (GUI) window, ''samterm'', which additionally allows point-and-click operations through pop-up context menus. This two-process structure allowed sam to access files on networked h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plan 9 From Outer Space
''Plan 9 from Outer Space'' is a 1957 American independent science fiction-horror film produced, written, directed, and edited by Ed Wood. The film was shot in black-and-white in November 1956 and had a theatrical preview screening on March 15, 1957, at the Carlton Theatre in Los Angeles (the onscreen title at this time read ''Grave Robbers from Outer Space''). It went into general release on July 22, 1959, in Texas and several other southern states re-titled ''Plan 9 from Outer Space'', before being sold to television in 1961. The film stars Gregory Walcott, Mona McKinnon, Tor Johnson, and "Vampira" (Maila Nurmi) and is narrated by Criswell. It also posthumously bills Bela Lugosi (silent footage of the actor had been shot by Wood for another, unfinished film prior to Lugosi's death in August 1956, and was inserted into ''Plan Nine'' later). Other guest-stars are Hollywood veterans Lyle Talbot, who claimed that he never refused any acting job, and former cowboy star Tom Keene ...

SunOS
SunOS is a Unix-branded operating system developed by Sun Microsystems for their workstation and server computer systems. The ''SunOS'' name is usually only used to refer to versions 1.0 to 4.1.4, which were based on BSD, while versions 5.0 and later are based on UNIX System V Release 4, and are marketed under the brand name ''Solaris''. History SunOS 1 only supported the Sun-2 series systems, including Sun-1 systems upgraded with Sun-2 (68010) CPU boards. SunOS 2 supported Sun-2 and Sun-3 (68020) series systems. SunOS 4 supported Sun-2 (until release 4.0.3), Sun-3 (until 4.1.1), Sun386i (4.0, 4.0.1 and 4.0.2 only) and Sun-4 (SPARC) architectures. Although SunOS 4 was intended to be the first release to fully support Sun's new SPARC processor, there was also a SunOS 3.2 release with preliminary support for Sun-4 systems. SunOS 4.1.2 introduced support for Sun's first sun4m-architecture multiprocessor machines (the SPARCserver 600MP series); since it ...
