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.

How this was created: Claude Code analyzed the entire codebase - routes, controllers, models, concerns, views, JavaScript, CSS, tests, and configuration. The goal was to extract not just what patterns are used, but why - inferring philosophy from implementation choices.

Setting up XEN on a Hetzner Dedicated Server

Author: Michael van Rooijen (@mrrooijen)

DISCLAIMER: I am a programmer, not a sysadmin in my day-to-day life. I provide this guide simply as a self-reference, and as a way to contribute to the community of developers. The main motivation for writing this guide is because of the lack of properly written guides/tutorials. They were either out-dated, inaccurate, in a non-English language or simply too vague to understand (at least for me, as a programmer and not a sysadmin).

I hope this guide helps getting you up and running with your own collection of VPS's on your own Dedicated Server over at Hetzner.de.

How to enable SSL with [Redis] ([Ruby Driver]) on [RedisLabs].

Typically, this is how you'd connect to Redis:

Redis.new(url: ENV["REDIS_URL"])

Where REDIS_URL uses the following format:

# Downloads MongoDB Version 1.2.2 to the Home Dir
# Extracts it and moves the contents into the /var/mongodb folder
# Creates a symlink from /var/mongodb/mongod to /usr/local/sbin
cd ~/
wget http://downloads.mongodb.org/linux/mongodb-linux-x86_64-1.2.2.tgz
tar -xf mongodb-linux-x86_64-1.2.2.tgz
mkdir -p /var/mongodb
mv mongodb-linux-x86_64-1.2.2/* /var/mongodb/
ln -nfs /var/mongodb/bin/mongod /usr/local/sbin
