Open Source’s Journey: From UNIX to Linux and Intel’s Global Collaboration

Preface

The Open Atom Foundation, the first domestic open‑source foundation, hosted the inaugural "Open Atom Global Open‑Source Summit," marking the first event labeled "global open source." The summit showcased global open‑source achievements and aimed to bring Chinese open‑source strength onto the world stage. The author, a long‑time open‑source enthusiast and contributor, felt the passion and vitality of China’s open‑source development, especially noting the Intel x86 CPU platform’s collaboration with domestic OS communities OpenEuler, OpenAnolis, and OpenCloudOS.

The author was excited to exchange ideas with many like‑minded participants, meeting new and old friends, embodying Linus’s view that "open source is a celebration of idealists."

From a historical perspective, open source empowers not only a shared future but also decides the future.

The Intel‑enabled domestic software ecosystem demonstrates that open‑source innovation relies on extensive international cooperation.

Open Source Wins the Future: Closed Source Undermined UNIX, Open Source Empowered Linux

The summit’s theme was "Open Source Enables a Shared Future," reflecting the ideal of "technology for good, benefiting society." After attending, the author reframes it as "Open Source Enables, Wins the Future," and begins with a historical review.

UNIX originated in 1974 at Bell Labs, developed by Ken Thompson and Dennis Ritchie. Bell Labs initially released the source for educational purposes, making UNIX Version 5 a textbook example for OS courses.

AT&T, constrained by the Sherman Antitrust Act, could not sell non‑telecommunication products and later split into the "AT&T Seven Sisters." After the breakup, AT&T commercialized UNIX, releasing System V (based on UNIX Version 7) and stopped providing source code to schools. Licenses cost $40,000 each, prohibiting most users.

During the 1970s‑80s, UNIX was largely a closed‑source commercial product, prompting many enthusiasts to form alliances against its commercialization. The GNU project, launched by Richard Stallman in 1983, aimed to recreate the collaborative spirit of early software development and build a complete free operating system compatible with UNIX.

By 1990, the GNU suite included GCC, GLIBC, GDB, TeX, Emacs, X Window System, Apache, and shells, but lacked a kernel. Meanwhile, Dutch professor Andrew Tanenbaum created Minix for teaching, which inspired Linus Torvalds.

In 1991, Linus Torvalds, a student at the University of Helsinki, wrote a simple kernel (Linux 0.0.1) for Intel 80386, later releasing Linux 1.0 in 1993 as a fully functional kernel. The open‑source model, described by Eric Raymond in "The Cathedral and the Bazaar," contrasted centralized, closed development with decentralized, collaborative development, influencing the broader IT industry.

Linux combined with the GNU suite formed a complete free operating system, attracting developers away from UNIX. By 1995, Linux paired with the Apache HTTP Server became the dominant platform for web servers, establishing the classic LAMP stack.

The history shows that open‑source principles have driven technological progress, fostering collaboration, innovation, and resistance to monopolistic control.

Open Source Innovation: Hardware‑Software Co‑Creation and Ecosystem Building

While open source is often associated with software, hardware plays a crucial role. Linux has been developed around Intel CPU features, and Intel remains a major contributor to the kernel (e.g., Kernel v5.10).

Intel positions itself as a data company and a software‑first company, aiming to extract value from customer data and enable high‑performance software.

A notable example is the collaboration between Intel’s x86 platform and Chinese OS communities OpenEuler, OpenAnolis, and OpenCloudOS. This partnership leverages Intel’s global expertise and the communities’ local knowledge to create a localized open‑source ecosystem, enhancing performance, compatibility, and commercial success.

The case highlights the importance of international cooperation for technological innovation and the value of localizing open‑source projects to meet regional needs.

Overall, the open‑source spirit of "banding together" and shared consensus makes large‑scale collaboration possible, driving a vibrant ecosystem that benefits both global and domestic participants.
