Knowra GNU Project GNU Project The GNU Project is a free software initiative launched by Richard Stallman in 1983 to build a Unix-like operating system and defend users’ freedom to run, study, change, and share software.
GNU General Public License : A family of copyleft licenses that grants software users freedoms to run, study, modify, and redistribute programs. The GPL became the project’s main legal instrument for preserving software freedom in derivative works.
Richard Stallman : An American programmer and free-software activist who founded the GNU Project and the Free Software Foundation. Stallman announced GNU and shaped its technical goals and ethical principles.
Free-software movement : A social movement advocating users’ freedom to run, study, modify, and share software. GNU is one of the movement’s central projects and its best-known technical undertaking.
GNU/Linux naming controversy : A dispute over whether systems combining GNU software with the Linux kernel should be called GNU/Linux or Linux. The naming dispute reflects disagreement about GNU’s contribution and the political meaning of software freedom.
GNU Compiler Collection : A suite of compilers for languages including C, C++, and Fortran, maintained as part of the GNU project. GCC supplies the compiler toolchain used to build much of the GNU system.
GNU Manifesto : A 1985 essay by Richard Stallman explaining the GNU Project and calling for contributions to a free Unix-like system. The manifesto publicly set out the project’s purpose and invited participation.
Four essential freedoms : The Free Software Foundation’s formulation of users’ freedoms to run, study, modify, and redistribute software. These freedoms express the project’s ethical standard for software, beyond whether it is technically capable.
Debian : A community-developed operating-system project that distributes Linux-based systems and many other free software packages. Debian’s GNU/Linux system helped bring GNU tools and free software to a broad user community.
GNU Core Utilities : A collection of basic command-line tools for file, text, and process operations on Unix-like systems. These utilities provide familiar commands such as ls, cp, and cat in GNU environments.
MIT Artificial Intelligence Laboratory : A research laboratory at the Massachusetts Institute of Technology, known for early work in artificial intelligence and computing. Stallman’s experience there informed his account of a collaborative software culture in decline.
