The Collaborative software development model is a style of software development whose focus is on public availability and communication, usually via the Internet.
The software development model began widespread adoption with the Linux kernel in 1991. Linux is an operating system kernel used by a family of Unix-like Operating systems These are popularly termed Linux operating systems and
It is the dominant model used in development of free software. Free software or software libre is Software that can be used studied and modified without restriction and which can be copied and redistributed in modified or unmodified It is very compatible with free software because free software projects publish the source code of any published programs, so they do not have the secrecy reason for hiding their communications and in-progress development. In Computer science, source code (commonly just source or code) is any sequence of statements or declarations written in some Human-readable
This development model is examined by Eric Raymond in his book The Cathedral and the Bazaar where he compares it to a Bazaar. Eric Steven Raymond (born December 4 1957 often referred to as ESR, is a Computer programmer, author and Open source software advocate The Cathedral and the Bazaar (abbreviated CatB) is an essay by Eric S
Massive scale peer review of software changes is possible under the collaborative development model. This has been summarised by Raymond in what he terms Linus's Law: many eyeballs make all bugs shallow. Linus's Law can refer to two different notions both named after Linus Torvalds.
However, the extent that such peer review actually occurs is disputed [1].
