What is the DRY principle in The Pragmatic Programmer?

• Avoid Duplication: Advocates for a single, authoritative representation of knowledge within a system to prevent inconsistencies.
• Enhances Maintainability: Systems become easier to maintain and evolve, as changes are made in only one place.
• Applies Beyond Code: The principle applies to documentation, design, and any aspect of software development where knowledge is represented.

What is Design by Contract as described in The Pragmatic Programmer?

• Clear Expectations: Defines the rights and responsibilities of software components, ensuring each part knows what to expect from others.
• Preconditions and Postconditions: Involves specifying requirements before a function is called and guarantees after it completes.
• Improves Reliability: Enforces a clear agreement on component interactions, reducing the likelihood of errors.

How does The Pragmatic Programmer address debugging?

• Mindset for Debugging: Emphasizes adopting a calm and analytical mindset, encouraging developers to focus on problem-solving.
• Reproduce Bugs: Advises making bugs reproducible to understand the conditions leading to the issue.
• Use Assertions: Recommends using assertions to catch errors early and improve code reliability.

What is the significance of version control in The Pragmatic Programmer?

• Essential for Collaboration: Crucial for managing code changes, preventing conflicts, and maintaining a history of changes.
• Rollback Capabilities: Acts as a "giant undo key," allowing developers to revert to previous code states if issues arise.
• Facilitates Experimentation: Encourages experimentation by allowing developers to create branches for new features or fixes.

How does The Pragmatic Programmer suggest handling resources?

• Finish What You Start: Advises that the function or object allocating a resource should also deallocate it, ensuring clear ownership.
• Use Scoping: Recommends using scoping mechanisms to manage resource lifetimes, reducing the risk of leaks.
