Reviving Legacy: A Decade of Evolution ‐ Modernizing Critical Python Projects

Introduction:

Briefly introduce your two critical Python projects.

Highlight their age and the technical debt that has accumulated over the years.

Emphasize the importance of keeping legacy projects up to date and the impact on maintainability and performance.

Section 1: Recognizing the Need for Change

Discuss the factors that led to the decision to modernize and refactor the projects.

Highlight the challenges and issues that had become evident.

Hard to change and to add new features

Explain how evolving technology and user needs influenced the decision.

Kitchen-sink with dishes, it won't go away, it just gets more.

Section 2: Planning and Strategy

Describe the planning process, including defining project goals, objectives, and success criteria.

Explain how you prioritized which parts of the project to refactor.

Discuss the technology stack, libraries, and tools chosen for the modernization.

Section 3: Codebase Analysis and Cleanup

Share the methods and tools you used to assess the existing codebase.

Mypy turned out to be very useful, guiding the process and flagging up issues early. Also refactor and extend the tests.

Discuss the process of identifying and addressing technical debt.

Highlight specific code areas or patterns that required the most attention.

Section 4: Refactoring and Improvements

Sandy Metz: All the little things.

Detail the specific refactoring techniques and practices used.

Explain how you improved code readability, maintainability, and performance.

Share any notable success stories or challenges faced during the refactoring process.

False starts and premature optimizations. Merge now or merge never.

Section 5: Testing and Quality Assurance

Describe the testing strategies and methodologies employed.

Explain how you ensured that the modernized code retained its integrity.

Share insights into regression testing and maintaining backward compatibility.

Section 6: Adoption of Best Practices

Discuss the adoption of modern best practices in Python development.
