All About Free Software
The FSF advocates for free software ideals as outlined in the Free Software Definition, works for adoption of free software and free media formats, and organizes activist campaigns against threats to user freedom like Windows 7, Apple’s iPhone and OS X, DRM on ebooks and movies, and software patents.
The GNU Project was launched in 1984 to develop a complete Unix-like operating system which is free software: the GNU operating system.
Unix-like operating systems are built from a collection of libraries, applications and developer tools, plus a kernel to allocate resources and talk to the hardware — Hurd, GNU’s kernel is actively developed, but is still some way from being ready for daily use, so GNU is often used with the kernel Linux.
The combination of GNU and Linux is the GNU/Linux operating system, now used by millions.
Sometimes this combination is incorrectly called Linux. There are many variants or “distributions” of GNU/Linux
Open source is a development method for software that harnesses the power of distributed peer review and transparency of process. The promise of open source is better quality, higher reliability, more flexibility, lower cost, and an end to predatory vendor lock-in.
The Open Source Initiative (OSI) is a non-profit corporation formed to educate about and advocate for the benefits of open source and to build bridges among different constituencies in the open-source community.
One of our most important activities is as a standards body, maintaining the Open Source Definition for the good of the community. The Open Source Initiative Approved License trademark and program creates a nexus of trust around which developers, users, corporations and governments can organize open-source cooperation.
