Exploring the History of Linux: A Timeline

The Linux story starts in 1991. A Finnish student, Linus Torvalds, wanted a free operating system’s heart. This system now has over 23.3 million lines of source code thanks to Linus’ work. It’s a huge part of our technology world today.

About 2.76% of personal computers use Linux. However, over 90% of the world’s top supercomputers rely on it. It’s also the root of Android, which dominates the mobile market at about 71.85%. Distros like Red Hat, Debian, and Ubuntu have helped spread Linux around. They make it easy to use and more diverse.

Key Takeaways

• Linux development started with Linus Torvalds in 1991.
• Eric S. Raymond described the open-source development model, terming it the „cathedral and the bazaar”.
• Linux’s growth has led to its presence in desktops, supercomputers, and mobile devices through Android.
• By 2018, the Linux kernel version 4.15 included over 23.3 million lines of source code.
• Significant distributions include Red Hat, Debian, and Ubuntu.

Events Leading to the Creation of Linux

The Linux operating system grew from major events and innovation in tech. It includes the Unix system, the GNU Project, MINIX’s influence, and the Intel 386 introduction.

Unix and its Influence

The Unix system launched in 1970 radically changed operating systems. Developed at AT&T Bell Labs by Ken Thompson and Dennis Ritchie, Unix was widely portable. It moved to the C language, attracting both academics and businesses.

UC Berkeley’s BSD project in 1977 was also inspired by Unix. However, a legal clash with AT&T slowed BSD’s growth. By 1980, companies like Onyx and Sun were offering Unix workstations, further spreading its reach.

GNU Project and Free Software Movement

Richard Stallman started the GNU Project in 1983 to make a free Unix-like system. He stressed the need for software freedom, leading to the GNU GPL. This ensured software would always be open for collaboration and growth.

The GNU Project’s work meshed with the Linux kernel, embracing the mission for open, free software.

Introduction of MINIX

MINIX, a Unix-like OS, was made for education by Andrew S. Tanenbaum in 1987. While important, its 16-bit and licensing issues held it back. Linus Torvalds was inspired to start Linux to address these obstacles.

Emergence of Intel 386

In 1985, the Intel 80386 came out, a major leap for processors. Its 32-bit design and virtual memory improved computing greatly. This set the stage for Linux, utilizing the processor’s power in 1991.

Linus Torvalds created Linux to blend Unix’s strengths and new software freedoms. The Intel 386’s features were key in developing this successful OS.

Year	Development	Impact
1970	Unix First Released	Increased Portability and Adoption
1983	GNU Project Initiated	Introduction of Free Software
1985	Intel 80386 Processor	Advanced Computing Capabilities
1987	Release of MINIX	Educational Prototype Inspires Linux
1991	Linux Kernel Development Begins	Combining Unix Principles and New Hardware

The Birth and Naming of Linux

Linux was started by Linus Torvalds in 1991 at the University of Helsinki. He made the kernel for his 80386 PC.

Initial Development by Linus Torvalds

At first, Torvalds looked at SunOS and MINIX docs for help. He released version 0.01 with GNU’s Bash shell. It was the beginning of a new era in operating systems.

The Iconic Announcement

Linus announced Linux on the comp.os.minix newsgroup in August 1991. It was just a hobby project for him. Little did he know it would change computing forever.

The Naming Journey

Linus wanted to name his project „Freax”, but his friend called it „Linux”. This name stuck and soon everyone was using it.

Linux Goes Open Source

In 1992, Linux became open source with the GNU GPL license. This meant anyone could use and improve it. This made Linux what it is today.

„I’m doing a (free) operating system (just a hobby, won’t be big and professional…)” – Linus Torvalds, 1991

Check out key moments in Linux’s history:

Year	Event
1991	Initial release of Linux kernel by Linus Torvalds
1992	GNU GPL licensing adopted for Linux kernel
1996	Introduction of Tux, Linux’s official mascot
2018	Release of Linux kernel version 4.15

From Linus Torvalds’ early ideas to Linux’s success, it all started with a small project. Over time, Linux became a key figure in open source.

Conclusion

In 1991, Linus Torvalds created Linux, which changed both personal and business computing. From being a college project, it became key to many systems worldwide. It now runs over 90% of top supercomputers and around 2.76% of all desktops. The Linux kernel, its core, manages all important system functions. This makes Linux the base of many tech advancements.

Linux plays a major role in the mobile market too. Most mobile devices, about 71.85%, use Android, which is built on Linux. Its reach shows how versatile and strong Linux is. Because it’s open source, anyone can modify and share its code for free. This has led to a big community of developers. They’ve made many different versions, like Ubuntu and Fedora, to meet various needs.

People like Linux because it’s stable and safe, and doesn’t cost much. Recent updates, such as the new Linux 5.11 and Ubuntu 21.04, keep making it better. Linux is also getting more important in cloud computing and virtual machines. Big names like IBM and Amazon use it. This shows how Linux continues to shape the tech world. And its community is working hard to make it even better and more widely used.

FAQ

What is the origin of the Linux kernel?

In 1991, Linus Torvalds started work on the Linux kernel. He was a student from Finland. This free and open-source project quickly grew popular. Now, it powers many devices worldwide.
