On August 25, 1991, a quiet student at the University of Helsinki, Linus Benedict Torvalds, posted a message that would revolutionize computing. From a seemingly modest announcement in the Usenet discussion group comp.os.minix, Linux has experienced an exceptional trajectory, establishing itself today as an essential pillar in the world of free and open-source operating systems. This article takes a detailed look at this pivotal moment, analyzing the context, the project’s early steps, its technical characteristics, and the impact it still has in 2025.
The Context of Linux’s Announcement in 1991: A Modest Birth for a Future Giant
The genesis of Linux took place in a technical and community environment where open-source and free software were already in development but far from dominant. In 1991, the Minix system, designed by Andrew Tanenbaum, served as a teaching reference for computer science students eager to understand the inner workings of an operating system. However, Minix had its limitations, notably its rigid architecture and non-free code, which left room for free and modular alternatives.
As early as April 1991, Linus Torvalds had begun developing his own kernel, not with an ambitious aim to revolutionize computing, but rather as a personal project in his spare time, which he described as “a hobby.” His Usenet post reflected this humility: he described a “simple” and “non-professional” system, intended for Intel 386 and 486 clones, which were beginning to become popular in the world of home and student PCs.
A few highlights from this context:
- The Minix community existed, with its advantages and its frustrations. The availability of Intel 386/486 processors favored the development of systems adapted to this architecture.
- Proprietary systems dominated, often imposing barriers to code changes or audits.
- The ideology of free software, driven in particular by GNU and the GPL license, was gaining momentum, opening the way to collaborative initiatives.
- In this context, the announcement on the comp.os.minix group was not a stunt, but an invitation to collaboration and the exchange of ideas, a basis which would quickly attract a growing community.

In his message, Torvalds lists several technical specificities of his project, which demonstrate both a practical vision and a spirit of innovation. Among these:
A multi-threaded system for file system management:
- this approach aimed for performance and responsiveness. No dependency on Minix code:
- in order to avoid the constraints linked to another base, particularly in terms of licensing and modularity. Code specific to the Intel x86 architecture:
- which limited initial portability, but allowed for targeted optimization. A modular and open design:
- the project anticipated external contributions, bug fixes and incremental improvements. With this version 0.01 planned for September 1991, Linus mainly wanted to offer a functional base on which other developers could rely. Far from aiming for a “ready-to-use” system, Linux was above all a field of experimentation and learning.
For example, while distributions like Red Hat, Debian, and Mandriva would emerge a few years later, enriching and making Linux systems more accessible, the technical foundation laid by Torvalds remained pragmatic and unpretentious. This clearly illustrates that this pioneering role laid the foundations for a complex, flexible, and evolving system.
In 2025, this technical flexibility is still at the heart of developments, with distributions such as Ubuntu, Fedora, and Arch Linux leveraging the regularly updated kernel, illustrated by frequent releases like Linux 6.17-rc3, marking improved performance and security.

An often overlooked aspect of the project’s launch is the choice of the name “Linux.” Linus Torvalds himself hesitated to use the term, deeming it too self-centered, almost egocentric. He initially chose “Freax,” a portmanteau of “free” and “x” to signify both free access and compatibility with Unix.
However, the administrator of the FTP server hosting the first version of the system took an independent initiative and named the download folder “linux.” This name then became the global standard, indelibly anchoring the project’s identity.
This anecdote illustrates the spirit of exchange and collective ownership inherent in open source, where the project can emancipate itself and grow through the community it unites. Many players, such as Slackware, SUSE, and CentOS, have contributed to expanding this universe by contributing their own technical visions and distribution philosophies.
A name chosen by a third party, not by the creator.
- A brand that has become synonymous with freedom and innovation.
- A symbol of identity facilitating global recognition.
- In 2025, this legacy continues and translates into a multitude of distributions adapted to all uses, whether for mainstream adoption, enterprise servers, or specific projects.
The Evolution of Linux Since 1991: From Volumes of Code to a Global Community
When version 1.0.0 of Linux was released in March 1994, the project was still modest in size, but already promising. Since then, its code has grown from a few thousand to tens of millions of lines, an exponential growth that testifies to the vitality of its community.
This growth fuels a proliferation of distributions, each committed to specific niches:
Debian:
- Known for its robustness and stability, it serves as the basis for several variants, including Ubuntu. Ubuntu: The ultimate consumer distribution, with a user-friendly interface and extensive hardware support.
- Red Hat / CentOS: Dominant in the enterprise, they guarantee security, support, and longevity.
- Fedora: Pioneer of cutting-edge technologies and short development cycles.
- Arch Linux: Preferred by tinkerers for its minimalism and extensive customization.
- This diversity illustrates Linux’s ability to meet diverse needs, whether in servers, desktop environments, or embedded systems. Furthermore, virtualization under Linux, for example via KVM, facilitates the integration of Windows and other operating systems, which is covered in detailed tutorials such as those available for mastering Linux in a multi-OS environment. https://www.youtube.com/watch?v=H9QtkzijrUg
The importance of collaboration is also evident in the open development process and the GPL license, which ensures that the code remains accessible and free. This model fosters the development of an entire generation of system administrators, developers, and enthusiasts.
More than three decades after its birth, Linux is installed everywhere, from web servers to smartphones, supercomputers, and the Internet of Things. Its portability, initially limited to x86, has spread to virtually every major architecture.
The power of the community and the diversity of distributions, such as those mentioned above, ensure constant adaptation to market needs, whether in terms of performance optimization, as revealed by recent benchmarks on Linux and AMD processors, or the integration of artificial intelligence into the kernel, a topic that is increasingly studied.
In particular:
Linux powers the majority of cloud infrastructures, notably via systems based on Debian, Red Hat, and CentOS. Linux gaming is booming thanks to dedicated platforms and specialized distributions offering free and optimized games.
The rise of open-source technologies is stimulating collaboration between companies, universities, and independent developers.
- With the upcoming phase-out of Windows 10 and the announced arrival of SteamOS on desktop, 2025 could well mark a new milestone in the mainstream adoption of Linux.
- As such, it’s important to regularly check for new releases, such as the release of Linux 6.17-rc3, to stay up-to-date on performance and security.
