Configuration Management

The Turn of the Screwdriver

Runtime configuration, feature switches, and other adjustable hauntings

Henry James · 14 July 2026

A configuration value is never more frightening than when everyone is sure it came from somewhere else.

In prose of exquisite uncertainty, Henry James examines the uneasy household of modern configuration: environment variables, dynamic settings, secret rotation, precedence rules, and the terrible ambiguity of defaults. This is a practical manual for engineers who would like production to be configurable, but not possessed.

Contents

  1. The Governess Discovers an Environment Variable
  2. Defaults Seen at the Edge of the Lawn
  3. Precedence, Inheritance, and Other Unreliable Witnesses
  4. Restarting Bly Without Waking the Children

Published by Austenpunk, the distinguished imprint for engineers who believe that every production incident would be improved by a stronger sense of narrative irony.

This essential volume combines literary feeling, technical anxiety, and just enough documentation to suggest that somebody once understood the system.
