Dialog

Stacy: Hey Nick, I’ve been thinking a lot about our codebase lately. The complexity seems to be getting out of hand. Have you noticed it too?

Nick: Absolutely, Stacy. It’s becoming a real challenge. I think the maintainability is suffering because of it.

Stacy: Exactly. One thing I’ve been focusing on is improving readability. It’s amazing how much easier code is to work with when it’s clean and well-documented.

Nick: True, but readability is just one part of the puzzle. I’m also concerned about the coupling between our modules. High coupling is making it hard to make changes without breaking something else.

Stacy: Good point. We need better cohesion within our modules too. Functions and classes should have a single, clear purpose.

Nick: Right. We also need to think about modularity. Breaking down the system into smaller, independent modules could help manage complexity and improve scalability.

Stacy: Speaking of scalability, have you noticed any performance issues lately? I’m worried that as we scale, these issues will only get worse.

Nick: I have. Some of the algorithms we’re using are not optimal. We need to profile and optimize them to ensure they perform well under load.

Vocabulary

• High/Low Coupling
  Definition: Coupling refers to the degree of direct knowledge one module has of another. High coupling means that modules are highly dependent on each other, while low coupling means they are largely independent.
  Translation: acoplamento alto/baixo

• Cohesion
  Definition: The degree to which the elements of a module belong together. High cohesion means that the module has a well-defined purpose and tasks within the module are strongly related.
  Translation: coesão

• Modularity
  Definition: The design principle that breaks a system into smaller, manageable, and interchangeable components.
  Translation: modularidade

• Scalability
  Definition: The capability of a system to handle a growing amount of work or its potential to be enlarged to accommodate that growth.
  Translation: escalabilidade

• Optimal
  Definition: The best or most effective condition or degree.
  Translation: ótimo

• Profile
  Definition: The collection of data or the representation of characteristics about a particular subject or system, often used in the context of performance profiling.
  Translation: perfil

• Under Load
  Definition: The state of a system when it is processing a significant amount of work or data, often used to test performance and stability.
  Translation: sob carga

• Readability
  Definition: The ease with which a reader can understand and interpret a written text, often referred to in coding to describe how easily others can understand the code.
  Translation: legibilidade

• Getting Out of Hand
  Definition: Becoming chaotic, unmanageable, or difficult to control.
  Translation: saindo do controle

• Maintainability
  Definition: The ease with which a product or system can be maintained, including correcting defects, updating, and adapting to a changing environment.
  Translation: manutenibilidade

Sample sentences

• High/Low Coupling

  • High coupling between these two modules means that changes in one will likely require changes in the other.

  • The low coupling in our new design allows us to update individual components without affecting the entire system.

• Cohesion

  • The module exhibits high cohesion as all its functions are closely related to its core purpose.

  • Improving cohesion in your code can significantly enhance its readability and maintainability.

• Modularity

  • Modularity in software design enables developers to isolate and test individual components independently.

  • By focusing on modularity, the team was able to streamline the development process and reduce integration issues.

• Scalability

  • The scalability of our application ensures that it can handle increased traffic without performance degradation.

  • When planning for future growth, it's essential to consider the scalability of your infrastructure.

• Optimal

  • The optimal solution to this problem minimizes cost while maximizing efficiency.

  • To achieve optimal performance, we need to fine-tune several parameters of the algorithm.

• Profile

  • By profiling the application, we identified several performance bottlenecks that need to be addressed.

  • The user's profile includes detailed information about their preferences and past activities.

• Under Load

  • The server crashed under load during the stress test, indicating it cannot handle peak traffic.

  • Performance metrics gathered under load provide valuable insights into the system's stability and capacity.

• Readability

  • The readability of this code is poor due to the lack of comments and clear variable names.

  • Enhancing readability makes it easier for new team members to understand and contribute to the project.

• Getting Out of Hand

  • The project started getting out of hand when unexpected bugs kept appearing.

  • You need to manage your tasks better to prevent things from getting out of hand.

• Maintainability

  • The maintainability of the codebase improved significantly after we refactored the legacy modules.

  • Writing clean, well-documented code is crucial for long-term maintainability.
