Introduction

In the April 5, 2025 episode of Everything Everywhere Daily, host Gary Arndt delves into the intricate world of Open Source Software, exploring its origins, evolution, and profound impact on modern technology. By tracing the journey from early computing to today's ubiquitous open source applications, Gary provides listeners with a comprehensive understanding of how collaborative development has shaped the digital landscape.

The Evolution of Software: From ENAC to Early Computing

Gary begins by highlighting the ubiquity of software in modern devices, emphasizing its foundational role in all computer operations. He contrasts this with the early days of computing, where software was not as significant as hardware.

[02:30] Gary: "Software was just a set of instructions for which cables to set up and which switches to flip."

The discussion traces back to the Electronic Numerical Integrator and Computer (ENAC), built in 1945, the first programmable computer. Initially, programming involved physically rewiring cables and setting switches, making software more about hardware configuration than the abstract code we recognize today. This era saw software as a mere set of operational instructions rather than a standalone product.

The Sharing Culture in Early Software Development

As computing evolved, so did the culture around software. Gary explains that during the 1950s and 60s, software was freely shared among researchers and developers. Institutions like MIT, Berkeley, and Bell Labs fostered a collaborative environment where code was openly exchanged to solve common problems.

[10:15] Gary: "At MIT, Berkeley, and Bell Labs, programmers routinely shared code to solve problems and built upon each other's work."

This ethos was encapsulated by the formation of the Share User Group in 1955, one of the first computer user groups. Comprised of IBM mainframe customers, Share facilitated the sharing of software and resources, reinforcing the collaborative spirit of the early computing community.

The Rise of Unix and BSD

A pivotal moment in software history was the development of Unix at Bell Labs in 1969. Gary outlines Unix's significance as a multi-user, multitasking operating system that introduced crucial concepts like the hierarchical file system, pipes, and a shell-based command line interface.

[15:45] Gary: "Unix was created as a simpler, more flexible alternative to the complex resource-heavy systems of the time."

Due to a 1956 consent decree, AT&T was restricted from entering the computer hardware market, leading them to license Unix to universities at minimal fees and with source code access. This decision enabled institutions like the University of California, Berkeley to modify and enhance Unix, giving birth to the Berkeley Software Distribution (BSD).

Gary highlights that BSD, led by figures like Bill Joy, evolved into a full-fledged operating system, further cementing the tradition of openness and collaboration in software development.

The Free Software Movement and GNU Project

The shift towards proprietary software in the late 1970s and early 1980s sparked a counter-movement. Gary introduces the GNU Project, launched in September 1983 by Richard Stallman at MIT's Artificial Intelligence Laboratory.

[22:10] Gary: "GNU was designed to be Unix-compatible, containing no Unix code, and aimed to be a free and open operating system."

Stallman founded the Free Software Foundation (FSF) in 1985 to advocate for software freedom, emphasizing users' rights to use, study, modify, and share software. The FSF introduced the GNU General Public License (GPL), ensuring that software remained free and that derivative works retained the same freedoms.

The Emergence of Linux and GNU/Linux

Despite the GNU Project's progress, it lacked a critical component: a kernel. Gary recounts how in 1991, Linus Torvalds addressed this gap by releasing Linux under the GPL.

[28:50] Gary: "Linux became the missing piece to form a fully functional free Unix-like operating system called GNU/Linux."

The combination of GNU's utilities and the Linux kernel created a robust, open-source operating system that rapidly gained traction. Gary notes that while Linux struggled to dominate the desktop market, it became the preferred choice for web servers and supercomputers, underscoring its reliability and scalability.

The Open Source Movement and Its Rebranding

In the late 1990s, the Free Software Movement underwent a transformation to better integrate with the commercial sector. Gary explains that the term "Open Source" was coined to emphasize the practical benefits of collaborative development, such as higher quality, faster innovation, and lower costs, without the heavy ethical and political undertones of the original movement.

[35:20] Gary: "The term Open Source was developed as a way to rebrand and reframe the Free Software movement in more pragmatic, business-friendly terms."

This rebranding led to the creation of the Open Source Initiative (OSI), which sought to define and promote open source software through a more inclusive and commercially appealing framework. Major companies began adopting open source practices, significantly reshaping the software industry.

Differences Between Free and Open Source Software

Gary clarifies a common misconception between free software and open source software. While all free software is open source, not all open source software is free in terms of user freedoms.

[40:05] Gary: "If software is free, as in you don't have to pay for it, doesn't mean that it's open source. Someone could create a program and allow people to download it without payment, but still retain full rights to the code."

He explains that free software, as per the FSF, focuses on user freedoms, whereas open source pertains to the accessibility of the source code and collaborative development practices. Various licenses govern open source software, including the GPL, MIT License, Apache License 2.0, BSD License, among others. These licenses ensure that users can use, modify, and distribute the software while maintaining certain conditions, such as keeping derivative works under the same license.

The Pervasiveness of Open Source Today

Gary underscores the extensive influence of open source software in today's technology landscape. From operating systems to web browsers and beyond, open source is integral to numerous applications and services.

• Operating Systems: While Linux holds a modest 4% share of the desktop market, it dominates web servers and is the backbone of 72% of smartphone operating systems through Android.

• Web Browsers: Major browsers like Google Chrome, Microsoft Edge, Opera, Brave, and Firefox leverage open source projects like Chromium and WebKit.

• Web Infrastructure: The Apache web server, PHP, and MySQL—all open source technologies—are fundamental to the internet's infrastructure.

• Content Management Systems: Platforms like WordPress power 40% of all web pages, exemplifying the critical role of open source in content creation and management.

[45:30] Gary: "Open source software is absolutely pivotal to the working of the Internet. Take it away and everything would cease to function."

Moreover, open source alternatives exist for almost every proprietary application, including word processors, photo editing tools, and media players, making it an indispensable component of both commercial and personal computing.

Conclusion: The Impact of Open Source on Modern Computing

Gary concludes by reflecting on the fundamental role that open source software plays in today's digital ecosystem. Rooted in the early culture of sharing and collaboration, open source has become a cornerstone of innovation, enabling rapid advancements and widespread accessibility.

He attributes the success of open source to its inclusive and transparent development model, which fosters continuous improvement and adaptability. As the technology landscape continues to evolve, open source remains a driving force behind new developments, ensuring that software remains flexible, reliable, and accessible to all.
