Zen and the Art of Merging Code
A developer deleted three hundred lines that no one was using. The build broke in production. The senior developer asked, “Was the code being used?” “Yes, but by no one we knew.” “Then who was the user?” Beyond the Surface Every codebase holds ghosts. Functions nobody remembers writing. Modules that show up in no roadmap, […]
A developer added a comment: // TODO: fix this later. Five years later, the comment was still there. The developer had left the company. The code worked. The senior developer asked the team, “Whose TODO is this now?” No one answered. The senior added, “And what does it mean to fix something that does not […]
A team declared the old system unmaintainable and began a complete rewrite. Two years later, they shipped. Within months, developers were calling the new system unmaintainable. The senior developer mused, “If the disease followed us, perhaps we did not leave it behind.” Then: “What did we rewrite, the code or ourselves?” The Teaching Unfolds There […]
The developer refactored ruthlessly, eliminating all complexity. Every function was pure, every variable named perfectly. The senior developer looked at the pristine codebase and asked, “What dirt did you clean away, and where is it now?” And, “If the code is perfectly clean, what is it clean of?” Understanding the Koan The pursuit of clean […]
The developer built a tool that wrote code automatically. Thousands of lines appeared instantly. The senior developer asked, “Who understands this generated code?” The developer replied, “The generator does.” “And who understands the generator?” Sitting with the Koan Code generators represent one of the most transformative shifts in modern software development. They promise speed, consistency, […]
“We must pay down this debt!” declared the team lead. The senior developer asked, “If you pay it all, what will you owe then?” And, “Who is the creditor of technical debt?” Reflections We speak of technical debt as if it were a financial obligation, complete with interest rates and creditors waiting impatiently for payment.
