: This paper from the ACM Digital Library addresses the difficulty of debugging code after a compiler has rearranged it for performance.

Question every assumption. Bugs often hide in code that you are absolutely certain is correct. If the system is behaving incorrectly, your assumptions about how the code works are likely flawed. : This paper from the ACM Digital Library

Before diving into tools and techniques, it is essential to understand the mental framework required for effective debugging. Debugging can be frustrating because it forces developers to confront their own mistakes. To debug effectively, you must adopt a specific mindset: If you share with third parties, their policies apply

The term itself has roots in engineering history. While the story of Grace Hopper finding a literal moth in a Harvard Mark II computer relay in 1947 is the most famous instance, the word "bug" had been used to describe technical glitches since the days of Thomas Edison. Today, debugging consumes an estimated 50% of a developer's time, making it a foundational skill for any technologist. The Debugging Workflow

Beyond basics, I should include practical strategies and techniques. Things like binary search, logging, assertions, using debuggers, and rubber ducking are essential tools. Also need to cover common bug categories—syntax, logic, race conditions, memory leaks, Heisenbugs—so readers can recognize patterns.
