What is an Open Source Developer and How to Become One: The Ultimate Guide

Hey friend! I‘m thrilled to see you‘re interested in joining the exciting world of open source development. As a long-time open source contributor myself, I‘m happy to share everything I‘ve learned on the journey so far.

Buckle up – this is going to be a comprehensive deep dive into the life of an open source developer!

Open Source Software is Eating the World

Before we get into the details of being an open source developer, it‘s important to understand the massive growth and impact of open source software.

The concept of "open source" refers to source code that is publicly accessible for anyone to use, modify, and distribute. This is enabled through open source licenses like MIT, GPL, Apache, etc.

Over the past decade, open source adoption has exploded:

A 2021 survey by WhiteSource found a staggering 94% of developers use open source components in their codebases. The era of proprietary, closed-source software is waning.

This growth extends across industries:

• Cloud Computing – AWS, GCP, Azure, Alibaba Cloud all leverage open source like Linux, Docker, Kubernetes, and more in their infrastructure.

• Web – Frontend frameworks like React, Vue, Angular, and Backend stacks like Node.js, Django, Rails are open source.

• Mobile – Android is built on Linux and open source; iOS makes use of open source as well.

• Embedded Systems – Open source software like FreeRTOS and Zephyr RTOS power IoT and embedded devices.

• Automotive – Infotainment systems and self-driving car stacks use open source tools like ROS and Android.

• Finance – High frequency trading systems and stock exchanges integrate open source libraries for performance.

You get the idea – open source is ubiquitous across most software-driven industries. As Marc Andreessen famously said, "software is eating the world" – and open source is eating software!

Why is Open Source Software Thriving?

There are several key reasons driving the explosive growth of open source:

1. Community-Driven Innovation

Thousands of developers worldwide can collaborate openly to create better software faster than closed teams. Bugs and security issues are found and fixed quickly.

2. Transparency & Trust

All changes happen publicly on GitHub. Companies can verify code quality and security rather than blindly trusting closed vendors.

3. Flexibility & Control

OSS provides source code access to modify as needed. Companies are not locked into vendor contracts or roadmaps.

4. Cost Reduction

Open source licenses are free to use. Maintenance is done by the developer community, saving high licensing fees.

5. Interoperability & Integration

Open standards like Kubernetes enable easier integration between tools and hybrid cloud environments.

6. Skills Development

Developers learn by reading real-world code from open projects, accelerating their growth.

7. Democratization of Technology

Anyone can contribute improvements rather than a privileged few with closed-source access. This speeds up innovation.

These factors are driving every industry to adopt open source. And powering all these open source projects are dedicated developers like you!

What Does an Open Source Developer Do?

Now that you understand the appeal of open source software, let‘s explore the day-to-day work of developers who build it.

Open source developers contribute code, documentation, and feedback to open source projects. Their responsibilities include:

Coding Features & Fixes

• Implement new functionality based on feature requests
• Identify and resolve bugs in existing code
• Refactor code to improve performance, readability, etc.

Reviewing Code

• Analyze incoming contributions from other developers
• Ensure additions meet project standards for design, tests, docs etc.
• Provide feedback through GitHub pull requests and code reviews

Triaging Issues
