Собор и Базар: Размышления об Linux и открытом исходном коде.

Book by Eric S. Raymond

The Cathedral and the Bazaar: Musings on Linux and Open Source by an Accidental Revolutionary (abbreviated CatB) is an essay, and later a book, by Eric S. Raymond on software engineering methods, based on his observations of the Linux kernel development process and his experiences managing an open source project, fetchmail. It examines the struggle between top down and bottom up design. The essay was first presented by Raymond at the Linux Kongress on May 27, 1997 in Würzburg (Germany) and was published as the second chapter of the sametitled book in 1999. The illustration on the cover of the book is a 1913 painting by Lyubov Popova titled Composition with Figures and belongs to the collection of the State Tretyakov Gallery. The book was released under the Open Publication License v2.0 in 1999.

In 1998, the essay helped the final push for Netscape Communications Corporation to release the source code for Netscape Communicator and start the Mozilla project; it was cited by Frank Hecker and other employees as an outside independent validation of his arguments. Netscape's public recognition of this influence brought Raymond renown in hacker culture. When O'Reilly Media published the book in 1999 it became one of, if not the first, complete, commercially distributed books published under the Open Publication License. Jimmy Wales himself was inspired by the work (as well as arguments put forward in pre Internet works, such as Friedrich Hayek's article "The Use of Knowledge in Society"), arguing that "It opened my eyes to the possibility of mass collaboration". In 1999 Nikolai Bezroukov published two critical essays on Eric Raymond's views of open source software, the second one called "A second look at The Cathedral and the Bazaar". They produced a sharp response from Eric Raymond.
