You've probably come across the term "Open Source." But what does it really mean, and why is it essential for you as an emerging developer? In this post, we’ll dive into the world of open source to help you understand its significance, history, and impact.

What is Open Source?

Open source refers to a system where the original design, often in the form of source code in software, is made publicly accessible. It originated as a concept within software development but has now become a broader movement, embodying values like open exchange, transparency, and community-oriented development. With Open Source software, you're allowed to inspect, modify, and enhance the code.

Open Source Software vs. Proprietary Software

Unlike proprietary or "closed source" software, such as Microsoft Office and Adobe Photoshop, open source software like LibreOffice allows you to access and modify the source code. Proprietary software restricts these freedoms; you must abide by strict licensing terms that typically forbid you from altering or distributing the software. Open source, on the other hand, comes with licenses that generally allow you to use the software as you wish, even encouraging you to contribute to its development.

History and Evolution

The concept of open source dates back to the late 1970s and early 1980s, eventually gaining mainstream acceptance. From Linux to Apache Web Server, foundational technologies of the modern Internet were built on open-source software. Today, the reach of open source extends beyond software and into various aspects of life, like education, government, and healthcare.

The history of open source software dates back to the 1960s when commercial computers were first distributed with source code. The trend died in the 1970s, when proprietary software became more common.

The open-source movement began in the late 1980s with the GNU project, which was launched by Richard Stallman. The term "open source" was coined in 1998. The Open Source Initiative (OSI) was formed in February 1998 by Eric Raymond and Bruce Perens.

The term "open source" was adopted by the Linux, Perl, and Python communities, as well as companies like Netscape and Red Hat. The Internet and the increasing presence of software led to more developers sharing their code openly.

The popularity of open source software increased in the late 1990s and early 2000s as large tech companies, such as IBM, began to support the concept. Today, open source software is used in a variety of applications, including web servers, databases, and programming languages.

Why Does Open Source Matter?

Here are some key reasons:

  1. Control: Users gain control over the software and can modify it to suit their needs.

  2. Training: Aspiring developers can study and learn from Open Source code, making it an educational asset.

  3. Security: With many eyes on the code, vulnerabilities can be quickly spotted and fixed.

  4. Stability: Long-term projects benefit from Open Source software because its survival doesn't depend on a single creator.

  5. Community: Open source fosters a collaborative environment that goes beyond software development.

Open Source Beyond Software

Open source isn't limited to software development; it's a philosophy. This approach applies to anything that can be shared, modified, and distributed, whether it's a recipe, a set of blueprints, or an organizational model. Open source values are manifesting in various fields, enhancing collaboration and accelerating innovation.


Open source is more than just a development methodology; it’s a way of life that promotes transparency, collaboration, and community. For new developers, engaging with open source is not just a learning experience, but also an opportunity to contribute to society in a meaningful way. Understanding open source can help you make informed decisions in your coding journey and could even be the stepping stone for exciting opportunities in your career.
