It’s been 25 years since the late Ian Murdock, the founder of the Debian project, send his famous email to the comp.os.linux.development mailing list announcing that he is working on a new release and was looking for suggestions. He called it the Debian Linux Release, which was put together from scratch by the Linux software developer, though it was inspired by Softlanding Linux System (SLS). Now, 25 years later, the Debian GNU/Linux operating system is used by millions of computer users worldwide and supported on more than ten architectures. It’s one of the most acclaimed and popular Linux-based OS for personal computers and servers alike, on which some of the world’s most popular Linux OSes are based on Debian, including Ubuntu. Even Apple and Google adopted Debian’s .deb file format.
