Open source software or software with source code is easily accessible to users to modify as needed, with controversial antecedents to date. With the advances in technology and technology in the modern era, patenting and licensing of software has become a highly profitable business, as it is certified by Microsoft's software giant. However, the humble beginnings of software originated from the open source code model.
Richard Stallman, an employee of the Massachusetts Institute of Technology (MIT), took up open source software in 1971, although he claims that the open-source community was present for many years. A number of user groups in the early period include the SHARE group for IBM 701 and DECUS for Digital Equipment Corporation (DEC). The existing operating systems, such as UNIX, scientists, and corporate researchers, provided a template for their work. Open source software was extremely valuable in this period because there were a number of hardware systems, so there was a need for changing software to answer technological needs in every situation.
In 1983, Richard Stallman launched the GNU project to write an enhanced OS with the source code available to the public. Shortly after the start of the project, he inserted "free software" and founded the Free Software Foundation. In 1991, the first version of the operating system was completed. However, Stallman et al called problems with the kernel system, called GNU Herd, which reduced the integration of all the components developed.
Simultaneously, the Linux kernel developed by Linus Torvalds was released as a source code in 1991. The Linux kernel is less complicated and more functional than the GNU Herd. When Stallman and his team integrated Linux with their work, the first free operating system was created. Software from the code association, known as Linux or GNU / Linux, is still available today.
The launch of "open source software" started in 1997, as opposed to "free software". Eric Raymond, a computer programmer, released the document "The Cathedral and the Bazaar", which reflects the direction of the hacker community and free software. The study encouraged the launch of an open source initiative aimed at promoting open source software and evangelizing its principles. As the open source community has grown in recent years, the community has been experiencing debate since the debate.
