Writing and Maintaining Accurate Documentation
Documentation for any type of technology project is crucial, especially if there are multiple people working on a project. Even if there's only one person, the human mind doesn't have perfect recall.
My home server started as a simple experimental playground for learning Unix-like operating systems, managing applications, and best-practices for file management. Over the past two years, the project ballooned into a media management server, web server, download client, chat host, cloud server, Git and development server with CI/CD integration all in one.
Each project by itself was manageable by itself, but as someone who is constantly learning and implementing new things, each project tended to build on the previous one. Then, when something broke due to an update or network blip (or more likely, an initial mis-configuration), I would have to go back and attempt to remember what I had done last time. This was annoying but not too big of a deal - it was just my personal project, and the time it would take to document each application wouldn't be worth the time it takes to troubleshoot my apps.
