Core Philosophy

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.

Using Unicorn with Upstart

This configuration works with Upstart on Ubuntu 12.04 LTS

The reason why it needs to be done this way (i.e. with the pre-start and post-stop stanzas), is because Upstart is unable to track whever Unicorn master process re-execs itself on hot deploys. One can use it without hot-deploys and run Unicorn in foreground also, it then only needs one exec stanza.

This presumes you are not using RVM, so no voodoo dances.

Patched ruby 1.9.3-p125 for 30% faster rails boot

What is?

This script installs a patched version of ruby 1.9.3-p125 with patches to make ruby-debug work again (#47) and boot-time performance improvements (#66 and #68), and runtime performance improvements (#83 and #84). It also includes the new backported GC from ruby-trunk.

Huge thanks to funny-falcon for the performance patches.

ruby-1.9.3-p484 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p484 with the railsexpress patchsets: https://github.com/skaes/rvm-patchsets

Requirements

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.
