Zen and the Art of Merging Code
The linter flagged two hundred warnings in the legacy file. A developer set out to fix them all. The senior developer watched. After an hour, the senior asked, “Has the code become better?” “It has become quieter.” “Are those the same thing?” Sitting with the Koan There is something deeply satisfying about a clean linter […]
The site was down. A developer pushed a one-line change directly to production. The next morning, the senior developer asked, “Did the fix work?” “Yes.” “Do you remember what you changed?” The developer paused, then opened the commit. They did not recognize their own hands. Sitting with the Koan There is a particular kind of […]
A developer wrote thorough documentation for their service. Years later, the service had changed entirely, but the documentation remained. The senior developer found a junior reading it earnestly. “What are you learning?” they asked. “How the service works.” “You are learning how it once worked. Is that the same thing?” The junior closed the document […]
The team spent months migrating to the newest framework. The old system was discarded. The senior developer asked, “What did the old framework teach you that the new one cannot?” And, “When you migrate code, what else travels with it?” The Teaching Unfolds Every few years, the software industry experiences a collective migration. React replaces […]
At standup, each developer spoke of their work. “I debugged the notification service yesterday,” said one. The senior developer listened, then asked, “When you found the bug, had it been waiting for you, or were you waiting for it?” “I… I don’t know.” “In the moment of discovery, who discovered whom?” Dwelling in the Question […]
A developer frantically debugged a critical production issue, chasing symptoms through log files and stack traces. “Every fix creates two new errors!” they cried to the senior developer. “Where is this chaos coming from?” The senior developer sat quietly, then asked: “What did you want when you first wrote this code?” “I wanted it to […]
A developer complained to the senior developer: “Every sprint, we fix bugs that create new bugs. Every feature spawns three more features. Every solution becomes tomorrow’s problem. When does it end?” The senior developer nodded. “Show me your deployment history.” Together they scrolled through months of releases: hotfixes begetting patches, patches requiring rollbacks, rollbacks necessitating […]
A junior developer discovered a massive, complex function in the legacy codebase—500 lines of nested conditionals, obscure variable names, and mysterious side effects. “This function is causing all our problems,” they told the senior developer. “Should I refactor it?” The senior developer examined the code, then deleted the entire function. “Wait!” cried the junior. “What […]
A junior developer approached the senior developer with a complex feature branch. “My code has eight different approaches,” said the junior. “Which path should I take?” The senior developer examined the pull request: Right Understanding of requirements, Right Intention in design, Right Speech in documentation, Right Action in implementation, Right Livelihood in sustainable code, Right […]
