refactoring

  • The shell script that is still a shell script

    Note2 min read

    A deploy script rewritten twice — into a compiled language and back — and stable for eighteen months at a hundred and eighty lines. Shell is the right…

  • Reviewing code I did not write

    Deep dive10 min read

    Review as the skill that matters, and a volume of code that needs it. A change that looks right, passes, and is subtly wrong.

  • A plugin with no admin screen

    Deep dive10 min read

    A plugin whose entire configuration is a constant and a filter, on a site whose deployment is a pipeline.

  • Boundaries drawn on a whiteboard, and the test that checks them

    Deep dive10 min read

    Note2 min read

    A shared setup action across four repositories, with eleven inputs, of which one repository used a combination nobody had tested. A shared abstraction with per-caller escape hatches is…

    Deep dive9 min read

    A site with 18 KB of JavaScript and a build pipeline sized for something larger. What a bundler provides, listed, and which of it is needed.

  • The PSR-18 client I wrote for one API

    Deep dive10 min read

    A supplier API with a signing scheme, a rate limit and a pagination style of its own, and the same four concerns implemented in three places.

  • The service class that was three procedures

    Note2 min read

    A class named for a noun, containing three methods that share no state and call nothing in common. A class whose methods share no dependencies is a namespace…
