Pro Git
Pro Git 2nd Edition
Welcome to the second edition of the Pro Git book. The entire Pro Git book, written by Scott Chacon and Ben Straub and published by Apress, is available here. All content is licensed under the Creative Commons Attribution Non Commercial Share Alike 3.0 license. Print versions of the book are available on Amazon.com. What is “version control”, and why should you care? Version control is a system that records changes to a file or set of files over time so that you can recall specific versions later. For the examples in this book, you will use software source code as the files being version controlled, though in reality you can do this with nearly any type of file on a computer. If you are a graphic or web designer and want to keep every version of an image or layout (which you would most certainly want to), a Version Control System (VCS) is a very wise thing to use. -

SICP PDF
SICP PDF with Texinfo and LaTeX source
sicp-pdf is a LaTeX-based PDF version of Structure and Interpretation of Computer Programs (SICP), the classic textbook by Harold Abelson, Gerald Jay Sussman, and Julie Sussman. It builds upon the earlier Unofficial Texinfo Format (UTF), which itself was derived from the MIT Press HTML version, but enhances the project by fully converting the source into LaTeX. This conversion allows for high-quality typesetting, improved design options, and the integration of OpenType and Unicode features through XeTeX. The repository contains both Texinfo and LaTeX sources, with automated scripts to keep them in sync during builds. Users can recompile the book locally with a recent TeX Live distribution and the necessary fonts, while Inkscape is required for SVG-to-PDF image conversions. The project is continuously refined to address formatting issues and ensure the text and figures render correctly across platforms. -

Chromebrew
Package manager for Chrome OS
The Missing Package Manager For Chrome OS. Chromebooks with ChromeOS run a Linux kernel. The only missing pieces to use as a full-featured Linux distro were gcc and make with their dependencies. Well, these pieces aren't missing anymore. Say hello to Chromebrew. In fact, Chromebrew is a simple Ruby script. There's also some Git involved, so we needed both of these things to run it on a bare Chrome OS. We have prebuilt them along with their dependencies to install into your system during installation. So, basically, after installing Chromebrew, you will have fully functional Ruby with Rubygems, Git, and a package manager dedicated just to your Chromebook. -

MailCatcher
Catches mail and serves it through a dream
Catches mail and serves it through a dream. MailCatcher runs a super simple SMTP server that catches any message sent to it to display in a web interface. Run mailcatcher, set your favorite app to deliver to smtp://127.0.0.1:1025 instead of your default SMTP server, then check it out to see the mail that's arrived so far. Shows HTML, Plain Text and Source version of messages, as applicable. Rewrites HTML enabling display of embedded, inline images/etc and opens links in a new window. Command-line options to override the default SMTP/HTTP IP and port settings. Mail appears instantly if your browser supports WebSockets, otherwise updates every thirty seconds. Sendmail-analogue command, catchmail, makes using mailcatcher from PHP a lot easier. Encodings are difficult. MailCatcher does not completely support utf-8 straight over the wire, you must use a mail library that encodes things properly based on SMTP server capabilities. -

Brakeman
A static analysis security vulnerability scanner for Ruby on Rails app
Brakeman is a free vulnerability scanner specifically designed for Ruby on Rails applications. It statically analyzes Rails application code to find security issues at any stage of development. Brakeman now uses the parallel gem to read and parse files in parallel. By default, parallel will split the reading/parsing into a number of separate processes based on number of CPUs. In testing, this has dramatically improved speed for large code bases, around 35% reduction in overall scan time. Brakeman will now track and return very simple literal values (e.g. strings, hashes of literals, arrays of literals) from very simple class methods (e.g. single line). Since ActiveRecord enums essentially generate some class (and instance) methods that return fixed literal values, the above class method return values is also used to support enum. -

CocoaPods
The Cocoa Dependency Manager
CocoaPods is a dependency manager for Swift and Objective-C Cocoa projects. It has over 82 thousand libraries and is used in over 3 million apps. CocoaPods can help you scale your projects elegantly. CocoaPods is built with Ruby and is installable with the default Ruby available on macOS. We recommend you use the default ruby. Using the default Ruby install can require you to use sudo when installing gems. Further installation instructions are in the guides. CocoaPods manages library dependencies for your Xcode projects. The dependencies for your projects are specified in a single text file called a Podfile. CocoaPods will resolve dependencies between libraries, fetch the resulting source code, then link it together in an Xcode workspace to build your project. Ultimately the goal is to improve discoverability of, and engagement in, third party open-source libraries by creating a more centralised ecosystem. -

Discourse
A platform for community discussion. Free, open, simple
Discourse is a modern, open-source discussion platform that rethinks forum software with an emphasis on civilized, long-lived conversations and community moderation at scale. It replaces dated bulletin-board paradigms with features like real-time updates, infinite scrolling, rich text composition, and progressive trust levels that let communities delegate moderation as members demonstrate good behavior. On the administrative side, Discourse provides powerful moderation tools—flagging, bulk actions, user silencing, and automated throttles—plus robust spam defenses and analytics to surface community health signals. The platform is extensible: a plugin system and well-documented APIs let organizations add integrations (SSO, chat bridges, badges, embeds) and tailor behavior without hacking core code. -

CSS-Only Chat
A truly monstrous async web chat using no JS whatsoever
css-only-chat is a proof-of-concept demonstration that implements a functioning chat interface using only HTML and CSS, without any JavaScript or backend logic. The project showcases creative use of CSS selectors, checkboxes, labels, and the :checked pseudo-class to mimic interactive behaviors normally handled by JavaScript. Messages are pre-written in the HTML and displayed based on user interaction, making it more of a playful experiment than a real messaging platform. Its main purpose is to illustrate the limits of CSS as a programming and UI tool, serving as both an educational example and a bit of humor within the developer community. By pushing CSS beyond its conventional role, it demonstrates how user interfaces can be simulated through styling tricks and static structures. Although not suitable for production use, it stands as a fun exercise in front-end creativity and unconventional coding challenges. -

DevDocs
API Documentation Browser
The devdocs repository powers the DevDocs web application, a fast, offline-friendly documentation browser for many programming languages, libraries, and APIs. It aggregates documentation from multiple sources (e.g., MDN, Python, Ruby, Git, etc.), converts them into a uniform format, and indexes them for instant text searching. The codebase includes a backend that handles ingestion, parsing, and transformation of documentation sources into a static site structure, as well as the client side UI code for browsing, searching, and reading docs in a responsive interface. DevDocs supports offline usage: users can download sets of docs for use without an internet connection, benefiting from caching and compact compressed storage. The repository includes scripts for updating doc sources, building, and deploying the documentation site. Because it is meant as a reference tool, performance and usability (e.g. fast search, minimal latency) are emphasized in design. -

GraphQL Batch
A query batching executor for the graphql gem
A query batching executor for the graphql gem. Provides an executor for the graphql gem which allows queries to be batched. Define a custom loader, which is initialized with arguments that are used for grouping and a perform method for performing the batch load. Use GraphQL::Batch as a plugin in your schema after specifying the mutation so that GraphQL::Batch can extend the mutation fields to clear the cache after they are resolved. The loader class can be used from the resolver for a graphql field by calling .for with the grouping arguments to get a loader instance, then call .load on that instance with the key to load. Although this library doesn't have a dependency on active record, the examples directory has record and association loaders for active record which handles edge cases like type-casting ids. GraphQL::Batch::Loader#load returns a Promise using the promise.rb gem to provide a promise-based API, so you can transform the query results using .then. -

Learning-SICP
Collection of Chinese cultural projects and course learning materials
Learning-SICP is a community project that localizes the MIT course “Structure and Interpretation of Computer Programs” (SICP) and curates complementary study materials for learners, especially Chinese-speaking Scheme/Lisp students. It focuses on translating the official lecture subtitles into Chinese while preserving the original English content for reference, providing an approachable path to a classic foundational course in computer science. The repository organizes translated subtitles, lecture indices, and supporting documents so learners can follow along with the full video series and consult the book and related readings as they study. Beyond subtitles, it aggregates links to the SICP text, environment setup guides, extended exercises, and FAQ resources to smooth first-time setup and deepen understanding of the material. -

Lolcat
Rainbows and unicorns
Lolcat is a command-line tool that colorizes terminal output by printing text in rainbow gradients. Inspired by the original Ruby “lolcat” project, it takes input from stdin or files and outputs the same text with colorful ANSI escape codes. It’s frequently used to add a playful touch to logs, help messages, or shell scripts, making otherwise mundane terminal output more fun. Options allow customizing color spread, speed, and randomization to create different rainbow effects. Lolcat is often piped into commands like cat, figlet, or fortune to create whimsical and eye-catching console art. Despite being lighthearted in purpose, it demonstrates the use of ANSI codes and stream manipulation in a clean, portable way. -

OmniAuth
OmniAuth is a flexible authentication system utilizing Rack middleware
OmniAuth is a library that standardizes multi-provider authentication for web applications. It was created to be powerful, flexible, and do as little as possible. Any developer can create strategies for OmniAuth that can authenticate users via disparate systems. OmniAuth strategies have been created for everything from Facebook to LDAP. In order to use OmniAuth in your applications, you will need to leverage one or more strategies. These strategies are generally released individually as RubyGems, and you can see a community-maintained list on the wiki for this project. One strategy, called Developer, is included with OmniAuth and provides a completely insecure, non-production-usable strategy that directly prompts a user for authentication information and then passes it straight through. You can use it as a placeholder when you start development and easily swap in other strategies later. -

RuboCop is a Ruby static code analyzer (a.k.a. linter) and code formatter. Out of the box it will enforce many of the guidelines outlined in the community Ruby Style Guide. RuboCop packs a lot of features on top of what you’d normally expect from a linter. Works with every major Ruby implementation. Autocorrection of many of the code offenses it detects. Robust code formatting capabilities. Multiple result for matters for both interactive use and for feeding data into other tools. Ability to have different configurations for different parts of your codebase. Ability to disable certain cops only for specific files or parts of files. Extremely flexible configuration that allows you to adapt RuboCop to pretty much every style and preference. It’s easy to extend RuboCop with custom cops and formatters. Many online services use RuboCop internally (e.g. HoundCI, Sider and CodeClimate). -
