Do It Yerself, Rube
summary
Finds 29 configuration gems and shows that picking one costs more time than writing a tiny Ruby solution that reads a single file for one app one config, merges environment vars, supports on‑change reload via inotify, and optionally signs/encrypts the file so executable ruby configs fail verification. Demonstrates using plain Ruby modules/classes, Pathname and nested OpenStructs instead of a gem, explains why abstractions leak, and reports the local solution works and is easier to audit.
