Mea Culpa - Dark Hours

Why it matters

A developer has pulled the plug on a web app called Dark Hours, a tool for viewing what is visible in the night sky, after learning it closely mirrored an existing open-source project, DarkHours.app. The original creator confronted him on Bluesky, pointing out the resemblance extended even to a bug he had already fixed. The developer initially proposed differentiating the features, renaming the project, and promoting the original work, but within roughly an hour concluded the overlap was too great to salvage. He redirected the domain to the original developer and abandoned plans for an iOS version. He apologized for careless reliance on Claude to generate the project, stressing he had never seen DarkHours.app beforehand but failed to check whether the AI output resembled existing work. He pledged to stop using Claude to build web projects, though he still uses it for questions and debugging on iOS software. The episode illustrates a growing accountability question around AI-generated code: when a model reproduces an existing project, responsibility for verification and attribution still falls on the person who ships it.
