When I was a kid, I practiced Scouting for eight years I picked up a lot of excellent values and my scouting experiences helped to shape my character and make me a better programmer. Let me show you why.
As a Scout, you get to experience nature by camping outdoors which teaches you one of the core values — respect life. Scout rules help support core Scout values. One of the first rules I learned was:
Always leave the campground cleaner than you found it.
Leave this world a little better than you found it.
What this rule represents is that you should not only pick up your trash, clean the area where you started a wood fire and the soil where you built your tent, but also you need to take a look at the campsite and do something to leave it better than it was before.
It is an explicit instruction. It helps you accept the notion that something can always be better. There’s always room for improvement. You had the opportunity to enjoy the area and its resources but you also have the opportunity to pay back by leaving the area in better shape for others.
I believe that when kids are taught this kind of values through games, repetition, and rewards, it becomes a habit. This is nominally known as positive reinforcement. Positive reinforcement takes place when a reward is presented as the result of certain behavior and the behavior increases. This trait has been embedded in my mind so that I don’t need to apply it consciously. It has become a behavioral reflex that integrates naturally in my day-to-day activities.
The Codebase Is the Developer's Campsite
Even if I don't go camping often nowadays, I follow this rule in a lot of different situations in my life. One of them is in my daily work — programming!
Working on a new feature or a bug feels excellent. Working on a codebase change feels like camping as a Scout. It is an opportunity to:
- Experience the environment.
- Understand the problem.
- Put what I know in practice.
- Use my skills to create solutions.
The codebase will host me for hours or days. Even if I don't enjoy the codebase too much, I still have to respect it because other people have worked hard on it. It gives me an opportunity to learn new things and to possibly use tools I have never been exposed to before.
"Even if we don't enjoy a codebase too much, we still have to respect it because other people have worked hard on it. We can work on taking little steps to improve it."
Once again, I have to assume that other people will get to "camp" in the project after me. People I haven't met yet and probably will never meet. They may be developers, project managers, even end-users. As thought leader and software craftsman Uncle Bob Martin says in his Scout Rule:
“Indeed, the act of leaving a mess in the code should be as socially unacceptable as littering. It should be something that just isn't done.”
Therefore, not only my work in the codebase needs to be clean, but it should leave the code at least a little better than I found it.
These are some examples in which I have applied this improvement of the status quo within a project:
- It took me 30 minutes to understand what this function does. Can I rename it to something more declarative or expressive so that others can understand it quicker than I did?
- I wasn't able to run this project with the provided instructions. Can I write the instructions that I followed but are not documented in a README file?
- This code is more convoluted than it should be. Can I make it easier and clearer?
- This function doesn’t have enough tests. Can I add some tests?
These small improvements will help my teammates and myself later. The code is not going to end up perfect, but it will be better than it was before. By following this practice, the code grows in a better direction with every action that you take on it.
"Small but powerful actions for teams that improve a codebase gradually: Vague naming? Make it explicit. Confusing code? Make it clearer. No documentation? Add steps to the README. Missing tests? Write one."
I have been doing software development for years and being a Scout had already prepared me to transfer the mindset and values exposed by Uncle Bob from the campsite to the codebase. But this approach is not an excuse for not allocating exclusive time and developers to fix issues in a codebase; it is just one way to continuously get things to a better state.
