The Unofficial 37signals/DHH Rails Style Guide

About This Document

This style guide was generated by Claude Code through deep analysis of the Fizzy codebase - 37signals' open-source project management tool.

Why Fizzy matters: While 37signals has long advocated for "vanilla Rails" and opinionated software design, their production codebases (Basecamp, HEY, etc.) have historically been closed source. Fizzy changes that. For the first time, developers can study a real 37signals/DHH-style Rails application - not just blog posts and conference talks, but actual production code with all its patterns, trade-offs, and deliberate omissions.

Reimplement the current branch on a new branch with a clean, narrative-quality git commit history suitable for reviewer comprehension.

Steps

1. Validate the source branch

   • Ensure the current branch has no merge conflicts, uncommitted changes, or other issues.
   • Confirm it is up to date with main.

2. Analyze the diff

• Study all changes between the current branch and main.

Z‑Image Turbo is a bit different from “classic” Stable Diffusion, so a lot of old prompting habits don’t quite apply. I’ll walk through how to prompt it deeply and safely, with special focus on controlling content (nudity, stereotypes, unwanted artifacts) even though the model does not support traditional negative prompts at all. ([Hugging Face][1])

1. How Z‑Image Turbo thinks (and why “negative” prompts don’t work)

Key facts that matter for prompting:

lnr Work Management System

Overview

lnr is an append-only, file-based lnr work management system designed for AI coding agents. Lnr work is organized into phases - coherent units of effort that match how AI agents naturally operate. The system requires no indices, no status tracking, and no complex tooling. State is derived entirely from which files exist in the directory.

Core Principles

Lnr work happens in phases, not issues or tickets. Each phase represents a coherent push toward a specific goal. Phases can be small (refactor a function) or large (implement authentication system).

How to deploy a Rails 7.1 app with Postgres and Kamal on a single server

I think you have looked at the tutorial from Mr. Heinemeier Hansson at least once or twice and have a similar setup.

rails new kamal_pg --css tailwind --skip-test --database=postgresql

cd kamal_pg

CONFIG WAS UPDATED - SEE COMMENTS

DEPRECATED
# This file contains pin mappings for the NON stock 2020 Creality Ender 3
# with the 32-bit Creality 4.2.2 board. To use this config, during
# "make menuconfig" select the STM32F103 with a "28KiB bootloader" and
# serial (on USART1 PA10/PA9) communication.
# adapted for my printer ender3-4.2.2 with some modifications and without the BLTouch.

# If you prefer a direct serial connection, in "make menuconfig"
