The not-too-clever programmer

This is a translation of grugbrain.dev into clear English. All props to the original author.

Introduction

This is a collection of thoughts on software development, originally written by an pseudonymous author styling themselves the "grug brain developer," but then translated into clear English by Raph Levien.

I am not an extremely smart developer, but I have many years of experience and have learned some things, although still don't know everything.
