  1. Legacy code issues often come from misunderstandings between developers rather than the code itself. Improving communication and ownership can help solve these problems.
  2. C++ is currently facing a divide between old and new users, which threatens its future. There's a struggle between keeping older features and moving towards modern innovations.
  3. Java's compilation speed has improved a lot, but using build tools can slow it down. Working directly with the compiler can make a big difference in speed.

  1. Encountered a memory leak with Java threads due to instantiation of threads but never starting them.
  2. Identified a database connection leak in a Java app due to a race condition in a connection pool initialization code.
  3. Fixed the issues by patching code, improving exception handling, and implementing best practices for thread and connection management.

Prefer Composition over Inheritance

  1. Composition is often better than inheritance because it allows you to create new classes by combining existing ones. This helps avoid complex class hierarchies.
  2. Using interfaces can help you achieve different behaviors without relying on a single inheritance path. This keeps your code flexible and clear.
  3. Delegation lets you pass tasks to other objects, which helps separate functionality and maintain cleaner, more understandable code.

Extra DRY with Literate Programming

🕹 Technology Software Development Programming Code Optimization Open Source
  1. Literate programming helps reduce code repetition by allowing you to define things in one place and use them throughout your project. This makes it easier to manage updates, like changing a copyright notice in multiple files with just one change.
  2. You can create variables in your project to store common values, like project names or copyright years, and include them wherever needed. This keeps your code clean and makes it easy to change values in the future.
  3. Using features like include guards in literate programming can help prevent issues when including files in your code. By generating names programmatically, you avoid conflicts and keep everything organized.
