Linux at 35: From a student's Usenet post to the backbone of the digital age
On August 25, 1991, Linus Torvalds announced a free operating system he was building as a personal project. That system, later named Linux, now runs the vast majority of web servers, cloud platforms, supercomputers, and Android devices. Torvalds had briefly considered calling it 'Freax' before settling on the name Linux.
Torvalds notes that Linux technically has four possible birthdays. The first public semi-mention came on July 3, 1991, when he requested POSIX documentation on the Minix newsgroup while mentioning an unnamed project. The famous August 25 post announced the hobby OS, September 17 marked the unannounced 0.01 release, and October 5 saw the first public distribution of version 0.02.
The University of Helsinki's computer science department played a quiet but meaningful role in Linux's early days. Though Linux was never an official university project, faculty were open to extracurricular work. The department eventually adopted Linux machines running X as thin clients and operated a DEC Alpha server running Linux in its server room, reflecting early institutional confidence in the system.
Linux's evolution from a student's side project to the foundation of global digital infrastructure means its stability now affects nearly everyone who uses the internet, mobile devices, or cloud services. As Linux underpins critical systems worldwide, its continued development could shape digital resilience for decades. The
