C News is a news server package, written by Geoff Collyer, assisted by Henry Spencer, at the University of Toronto as a replacement for B News. It was presented at the Winter 1987 USENIX conference in Washington, D.C.
A news server is a collection of software used to handle Usenet articles. It may also refer to a computer itself which is primarily or solely used for handling Usenet. A reader server provides an interface to read and post articles, generally with the assistance of a news client. A transit server exchanges articles with other servers. Most servers can provide both functions.
Geoff Collyer is a Canadian computer scientist. He is the senior author of C News, a protocol-neutral news transport, and the designer of NOV, the News Overview database used by all modern newsreaders.
Henry Spencer is a Canadian computer programmer and space enthusiast. He wrote "regex", a widely used software library for regular expressions, and co-wrote C News, a Usenet server program. He also wrote The Ten Commandments for C Programmers. He is coauthor, with David Lawrence, of the book Managing Usenet. While working at the University of Toronto he ran the first active Usenet site outside the U.S., starting in 1981. His records from that period were eventually acquired by Google to provide an archive of Usenet in the 1980s.
Functionally, the operation of C News is very much like that of B News. One major difference was that C News was written with portability in mind. It ran on many variants of Unix and even MS-DOS. The relaynews program that handled article filing and feeding was carefully optimized and designed to process articles in batches, while B News processed one article per program invocation. The authors claimed that relaynews could process articles 19 times as quickly as B News.
In software engineering, porting is the process of adapting software for the purpose of achieving some form of execution in a computing environment that is different from the one that a given program was originally designed for. The term is also used when software/hardware is changed to make them usable in different environments.
Unix is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, development starting in the 1970s at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.
MS-DOS is an operating system for x86-based personal computers mostly developed by Microsoft. Collectively, MS-DOS, its rebranding as IBM PC DOS, and some operating systems attempting to be compatible with MS-DOS, are sometimes referred to as "DOS". MS-DOS was the main operating system for IBM PC compatible personal computers during the 1980s and the early 1990s, when it was gradually superseded by operating systems offering a graphical user interface (GUI), in various generations of the graphical Microsoft Windows operating system.
In 1992, Collyer gave C News a new index facility called NOV (or News Overview). This allowed newsreaders to rapidly retrieve header and threading information with relatively little load on the server. Virtually all current [update] news servers continue to use this method in the form of the NNTP XOVER command. Development of C News stopped about 1995, and the package was largely superseded by INN.
The Network News Transfer Protocol (NNTP) is an application protocol used for transporting Usenet news articles (netnews) between news servers and for reading and posting articles by end user client applications. Brian Kantor of the University of California, San Diego and Phil Lapsley of the University of California, Berkeley wrote RFC 977, the specification for the Network News Transfer Protocol, in March 1986. Other contributors included Stan O. Barber from the Baylor College of Medicine and Erik Fair of Apple Computer.
XOVER is a Network News Transfer Protocol (NNTP) command used to return information from a news server's overview (NOV) database.
InterNetNews (INN) is a Usenet news server package, originally released by Rich Salz in 1991, and presented at the Summer 1992 USENIX conference in San Antonio, Texas. It was the first news server with integrated NNTP functionality.
A man page is a form of software documentation usually found on a Unix or Unix-like operating system. Topics covered include computer programs, formal standards and conventions, and even abstract concepts. A user may invoke a man page by issuing the man
command.
nroff
is a text-formatting program on Unix and Unix-like operating systems. It produces output suitable for simple fixed-width printers and terminal windows. It is an integral part of the Unix help system, being used to format man pages for display.
SAP R/3 is the former name of the enterprise resource planning software produced by the German corporation SAP AG. It is an enterprise-wide information system designed to coordinate all the resources, information, and activities needed to complete business processes such as order fulfillment, billing, human resource management, and production planning.
A News, originally known simply as news, was the first widely distributed program for serving and reading Usenet newsgroups. The program, written at Duke University by Steve Daniel and Tom Truscott, was released on a tape given out at the June 1980 USENIX conference held at the University of Delaware. Steve Daniel from Duke offered a presentation on the then-new Usenet network and invited attendees to join.
R is a programming language and free software environment for statistical computing and graphics supported by the R Foundation for Statistical Computing. The R language is widely used among statisticians and data miners for developing statistical software and data analysis. Polls, data mining surveys, and studies of scholarly literature databases show substantial increases in popularity in recent years. as of March 2019, R ranks 14th in the TIOBE index, a measure of popularity of programming languages.
Among the operators and users of commercial Usenet news servers, common concerns are the continually increasing storage and network capacity requirements and their effects. Completion, retention and overall system performance are the topics of frequent discussion. With the increasing demands, it is common for the transit and reader server roles to be subdivided further into numbering, storage and front end systems. These server farms are continually monitored by both insiders and outsiders, and measurements of these characteristics are often used by consumers when choosing a commercial news service.
NOV, or News Overview, is a widely deployed indexing method for Usenet articles, also found in some Internet email implementations. Written in 1992 by Geoff Collyer, NOV replaced a variety of incompatible indexing schemes used in different client programs, each typically requiring custom modifications to each news server before they could be used. In modern NNTP implementations, NOV is exposed as the XOVER and related commands.
Software deployment is all of the activities that make a software system available for use.
A software repository, colloquially known as a "repo" for short, is a storage location from which software packages may be retrieved and installed on a computer.
Dropbear is a software package written by Matt Johnston that provides a Secure Shell-compatible server and client. It is designed as a replacement for standard OpenSSH for environments with low memory and processor resources, such as embedded systems. It is a core component of OpenWrt and other router distributions.
Usenet is a worldwide distributed discussion system available on computers. It was developed from the general-purpose Unix-to-Unix Copy (UUCP) dial-up network architecture. Tom Truscott and Jim Ellis conceived the idea in 1979, and it was established in 1980. Users read and post messages to one or more categories, known as newsgroups. Usenet resembles a bulletin board system (BBS) in many respects and is the precursor to Internet forums that are widely used today. Discussions are threaded, as with web forums and BBSs, though posts are stored on the server sequentially. The name comes from the term "users network".
CGram Software is a Swansea-based software authoring company established in 1982. It provides accounting software, enterprise resource planning (ERP), CRM, production control and supply chain management software for small to medium-sized companies, and has a long history in the UNIX and Linux commercial world.

Quantcast File System (QFS) is an open-source distributed file system software package for large-scale MapReduce or other batch-processing workloads. It was designed as an alternative to the Apache Hadoop Distributed File System (HDFS), intended to deliver better performance and cost-efficiency for large-scale processing clusters.
