Kitchen Sink

Imagine you drink a glass of water and go to the kitchen sink to wash it. When you get there, there’s a HUGE pile of dirty dishes in the sink. To wash your glass, you would have to clean all the mess before. You look around… no one’s watching. You carefully put the glass in the sink’s corner and sneak out. You walk away thinking “How things got this way?”. The ironic answer comes to your mind: one glass a day.

In the same way, software accumulates technical debt over time. Most of the time, tech debt starts from simple actions:“let’s add another method to that class”, “let’s add another parameter to that function”, “let’s duplicate that code for the 10th time… What? Don’t look at me, it’s how everyone does this!”.

Giant classes/functions/modules are like magnets: they attract all responsibilities to themselves and tend to get even bigger! There is so much code stuffed inside that everything seems to fit in there. That creates a sort of black hole that won’t stop growing.

I’m not saying you should abstract early. I’m all aboard with ma’am Sandi Metz on “duplication is far cheaper than the wrong abstraction”, but an abstraction will have to exist at some point.

🚪 A way out

If you thought “I can’t touch this without breaking all the things”, you’re not the only one. Every developer will eventually deal with software that has technical debt and sometimes it may even seem that there’s no salvation. Luckily, smart folks like Martin Fowler taught us patterns for dealing with this very situation! The Strangler Fig Pattern, for example, allows us to refactor big classes (or even applications) incrementally, without breaking backward compatibility!

The point is, in the same way that there are design patterns for creating new code and addressing issues, there is a list of code smells and refactoring techniques to deal with them as well. Refactoring should be part of our daily work, not something ~special~. We should study, learn and teach others about it. The more we do it, the easier (and natural) it gets!

🎸 Gravity is working against me

Bad code attracts (more) bad code. Developers, especially when they’re new in a codebase, tend to repeat patterns. That way, expect a bad piece of code to influence similar instances. To prevent this we must resist inertia. Yeah, it’s easy just to follow what everyone’s been doing, but this approach won’t work forever.

How to do this? Following the boy-scout rule “always leave the code behind in a better state than you found it” helps to create a good mindset for it. We’ll think twice before just adding a new line of that huge method or nesting another if/else statement. This rule helps us not to be afraid of taking small actions to improve the code. Did we touch a function? How can we improve it? Does it have tests? Can we use code to get rid of some comments?

When we finally understand that piece of spaghetti code (everyone has at least one in mind), we won’t keep it to ourselves! We have to materialize this knowledge in the code itself by renaming variables, functions, extracting small methods to clarify intention, etc. It costs us a bit today but will save a ton of time for other developers (or ourselves in 6 months).

Those simple actions can be powerful in the long run! One glass a day, that dirty pile gets smaller. You may even have some partners joining this quest! Soon enough, that sink will be shining, and when it is clean, no one will want to be the first to leave a dirty dish there.

Renovations also provide an opportunity to make your home more accessible and adaptable to future needs. Universal design principles can be incorporated to create spaces that are both functional and accessible for individuals of all ages and abilities bathroom remodeling new york city. For example, installing lower countertops, pull-out shelves, and lever-style handles in the kitchen can make the space more user-friendly for those with mobility issues. Similarly, adding features like grab bars, a walk-in shower, and non-slip flooring in the bathroom can enhance safety and accessibility. These improvements not only benefit current inhabitants but also make your home more versatile in accommodating changing needs over time.
