Debugging java.lang.StackOverflowError from Recursion
A practical guide to diagnosing and fixing StackOverflowError caused by unbounded recursion in Java, including thread stack analysis, JVM flags, and code patterns that actually cause this.
Turborepo Cache Not Hitting – Debugging Remote and Local Cache Misses
A practical guide to diagnosing why Turborepo's cache is not hitting, covering both local and remote cache misses with concrete commands and root causes.
Nx Affected Command Not Detecting Changes: Debugging Guide
When `nx affected` commands fail to see your changes, the cause is almost always a mismatch between the git base and the project graph. This guide shows you exactly how to diagnose and fix it.
Husky Git Hook Not Running: Why Your Pre-commit or Commit-msg Hook is Silently Skipped
Diagnose why Husky hooks are not executing despite being installed. Covers .git/hooks issues, path problems, and permission errors.
React Native iOS Pod Install Error: Xcode Build Failures and CocoaPods Conflicts
A practical guide to diagnosing and fixing pod install failures in React Native iOS projects, covering version mismatches, cache issues, and FFI dependencies.
Expo EAS Build Fails: Debugging Build Errors on EAS
A practical guide to debugging Expo EAS build failures, covering common causes, diagnosis steps, and fixes for EAS Build errors.
Long-form thinking on debugging habits, observability, and the systems around the bug.
Assert Statements: Where They Help and Where They Hurt
Assert statements are a double-edged sword. Used correctly, they catch bugs early and document invariants. Used carelessly, they can mask failures and create security holes. Here's how to wield them effectively.
Debuggers vs Console.log: Why I Stopped Using Print Statements for Debugging
Print statements are the duct tape of debugging. They work for trivial issues, but for race conditions, async flows, or deep call stacks, a debugger saves hours. Here's what I learned after years of using both.
Treating Bugs as Hypotheses: How the Scientific Method Fixes Debugging
Frustrated by flailing through logs? The scientific method turns debugging into a reproducible process. Here's how to formulate hypotheses, design experiments, and isolate root causes with confidence.
How to Debug a Regression: A Practical Walkthrough
A practical, step-by-step guide to finding and fixing regression bugs, with real-world examples and concrete commands you can run today.
The Cost of Not Reproducing Bugs: Why Local Debugging Saves Hours
Skipping local reproduction leads to wasted hours, broken deploys, and frustrated teams. Here's why it's non-negotiable and how to do it right.
Debugging an Unfamiliar Codebase: A Systematic Approach
A repeatable process for debugging code you didn't write — with specific techniques, tooling choices, and a war story from a production outage at 2 AM.
