Runping Lai
Runping Lai enhanced the google/perfetto repository by delivering targeted UI improvements and code refactoring over a two-month period. He aligned Wattson’s power-estimate displays across package, thread, and process levels, improving both accuracy and readability for CPU power analysis. Lai modularized the warning system, separating display from generation logic to support easier maintenance and future extension. He also addressed energy calculation inconsistencies for threads with NULL UIDs. In October, Lai focused on maintainability by replacing magic numbers in SQL files with named functions and updating documentation to clarify macro usage, leveraging JavaScript, TypeScript, and SQL to ensure robust, maintainable code.

Sep 1, 2025September 2025 (2025-09) — Focused Wattson UI improvements and warning system enhancements in google/perfetto. Delivered aligned power-estimate display across package-, thread-, and process-level views; fixed energy calculation for threads with NULL UIDs; added user-visible warnings for missing trace events required for CPU track analysis; and modularized the warnings system for easier maintenance and future extension. Impact: more reliable CPU power estimates, faster analysis, and improved developer experience. Technologies: UI refactor, frontend/backend coordination, and trace-event-driven logic.
