Episode 148: Software Archaeology with Dave Thomas

Code Benefits

Reading source code is a crucial skill for developers, as emphasized by Dave Thomas. He argues that developers often spend more time reading existing code than writing new code, whether it's for fixing bugs or adding new features 1. This practice is akin to other creative professions where learning from existing works is essential. Thomas highlights the importance of recreational and educational code reading, suggesting that it should be a part of formal education 1.

If you're a software developer, you never read anybody else's code. You spend your entire time writing your own, which is an incredibly arrogant approach to the profession.

--- Dave Thomas

He advocates for more courses focused on code reading and appreciation, which could help developers improve their skills and understanding of programming techniques 1.

   

Beginner Tips

For beginners, Dave Thomas advises starting with manageable projects to build code reading skills. He suggests choosing open-source projects in familiar languages and focusing on smaller codebases of 5,000 to 20,000 lines 2. This approach allows beginners to ask simple questions and gradually understand the code's structure and functionality.

Don't set yourself the job of understanding the Linux kernel as your first code reading exercise.

--- Dave Thomas

Thomas also recommends forming groups to discuss code, akin to book clubs, which can provide diverse insights and enhance learning 3.
