A brief history of Linux operating system development

In the 1970s, the source code of Unix system can be spread mostly.

Internet TCP/IP based protocol is derived from that era. In that period, people in the creation of their respective "works" in enjoying engaged in scientific research and innovation activities that are unique to that kind of passion and sense of accomplishment. When programmers, like writers, eager to "publish" their program works, and not focus on conservative "confidential", in exchange for money. In 1979, AT&T announced business plans for Unix, the resulting various binary commercial Unix versions. They rise up based on binary machine-readable code "copyright industry" (CopyrightIndustry), so that the software industry as a copyright proprietary-industry, centering on the development of innovation activity was limited to some of the key enterprises of the coterie, source programs as core "business confidential". This approach, on the one hand resulted in a large number of commercial software, greatly promoted the development of the software industry, was born a batch of software giant; on the other hand, due to a closed development model, have also hindered the software industry for further deepening and enhancement. Thus, there is a commercial software "BUG" paid a heavy price. In 1984, RichardStallman face program development in closed mode, launched an international open source so-called cattle (GUN) plan, seeking to return to the 1970s opened based on source creative moments. He is the protection of open source libraries will not be renewed subject to commercial use of closed-end, has developed a GPL terms, called a Copyleft copyright model. June 1987, R.. Stallman completed 11 million lines of open source "compiler" (GNUgcc), was a major breakthrough, made a great contribution. November 1989, M.Tiemann to 6000 $ entrepreneurship, creating a focus on the business of open source "CygnusSupport" (Cygnus support company) open source projects. (Note that was implicit in the Cygnus gnu three letters). Cygnus is the world's first and final success of a franchise business company source code program. Cygnus "compiler" is the best, it has a lot of customers are leading IT companies, including the world's largest microprocessor company. November 1991, LinusTorvalds wrote a small program, named Linux and put it on the Internet. He expressed a wish, hoping to come up with an operating system kernel. This is a fortuitous event. However, in Internet, Linux is just a "outcrops", it was the majority of wildebeests plan of followers settled on, all play, pitched in, put it in either the machine into a full-featured operating system, called CNULinux. January 1995, BobYoung founded the RedHat (little Red Riding Hood) to CNULinux as core, integrated with 400 more source code open module, a to brand of Linux, that is, known as Linux RedHatLinux "release", sold in the market. This operating mode is a kind of pioneering work. BobYoung says: we never want to have your own copyright, proprietary technology, we sell is "easy" (for users with support, service), instead of their "proprietary techniques". Open source programs include various brand release, greatly contributed to the popularization and application of Linux.
