Software Development

A thread about small interfaces, clear boundaries, and the everyday habits that keep a codebase healthy.

Ada Fieldnotes1 min read1 min left

Software development is less a single discipline than a collection of habits. We decide how to name things, where to put boundaries, and when a shortcut is worth taking. The choices rarely look dramatic in isolation, but together they determine whether a system can absorb change.

This thread follows the practical side of that work: interfaces that stay small, errors that carry context, tests that describe behavior, and architecture that makes the next change easier instead of harder.
