RuboCop Rails
A RuboCop extension focused on enforcing Rails best practices
A RuboCop extension focused on enforcing Rails best practices and coding conventions. It’s based on the community-driven Rails style guide. You need to tell RuboCop to load the Rails extension. Now you can run rubocop and it will automatically load the RuboCop Rails cops together with the standard cops. If you are using Rails 6.1 or newer, add the following config.generators.after_generate setting to your config/application.rb to apply RuboCop autocorrection to code generated by bin/rails g. It uses rubocop -A to apply Style/FrozenStringLiteralComment and other unsafe autocorretion cops. rubocop -A is unsafe autocorrection, but code generated by default is simple and less likely to be incompatible with rubocop -A. If you have problems you can replace it with rubocop -a instead. -

Ruby on Rails
Web Application Framework written in Ruby
Rails is a web application development framework written in the Ruby programming language. It is designed to make programming web applications easier by making assumptions about what every developer needs to get started. It allows you to write less code while accomplishing more than many other languages and frameworks. Experienced Rails developers also report that it makes web application development more fun. -

StimulusReflex
Build reactive applications with the Rails tooling you already know
StimulusReflex is a Ruby on Rails framework for building reactive, real-time web interfaces without moving most application logic into a heavy frontend framework. It connects Stimulus controllers, Rails server-side actions, Action Cable, and CableReady to respond to user interactions over WebSockets. When a user clicks, types, submits, or triggers another event, the server processes the action and sends DOM updates back to the browser. This lets developers keep validation, persistence, authorization, and state changes close to their existing Rails code. The project is useful for dashboards, forms, admin tools, collaborative interfaces, and dynamic Rails applications that need fast updates with less JavaScript. It is best suited for Rails teams that prefer server-driven interactivity while still delivering a modern, responsive user experience. -

Username Anarchy
Username generator for penetration testing and user enumeration
Username Anarchy is an open source command line tool designed to generate possible usernames for use in penetration testing and security assessments. It focuses on solving one of the common challenges in authentication attacks: identifying valid usernames before attempting password attacks. It generates large sets of potential usernames based on a person’s name and common naming conventions used in corporate or online systems. These generated username lists can then be used for activities such as username enumeration, password spraying, or brute force testing during security audits. Username Anarchy supports numerous formatting styles, allowing security testers to replicate patterns commonly used in enterprise environments such as first.last, flast, or firstinitiallastname. Username Anarchy can also utilize name sources gathered from OSINT techniques such as social networks or other public data to produce realistic username lists. -

dotenv
A Ruby gem to load environment variables from `.env`
Shim to load environment variables from .env into ENV in development. Storing configuration in the environment is one of the tenets of a twelve-factor app. Anything that is likely to change between deployment environments–such as resource handles for databases or credentials for external services–should be extracted from the code into environment variables. But it is not always practical to set environment variables on development machines or continuous integration servers where multiple projects are run. dotenv loads variables from a .env file into ENV when the environment is bootstrapped. dotenv is initialized in your Rails app during the before_configuration callback, which is fired when the Application constant is defined in config/application.rb with class Application < Rails::Application. If you need it to be initialized sooner, you can manually call Dotenv::Railtie.load. -

FORTRAN Unit Test Framework (FRUIT)
FORTRAN Unit Test Framework FRUIT - TDD in FORTRAN
FORTRAN Unit Test Framework, written in FORTRAN 95. So that all FORTRAN features can be tested. FRUIT has assertion, fixture, setup, teardown, report, spec, driver generation. Rake used as build tool. Tutorials at http://fortranxunit.wiki.sourceforge.net The core testing part is in FORTRAN, this part can be used independent of the Ruby codes. The Ruby code is to make fixtures and reports easier. Rake is to build the project elegantly. This project also demonstrate a new way to build mixed language code in an alternative way than Make. Most of the FORTRAN are important in nature, used in nuclear and aerospace codes, etc, and maintained and written actively. Please help to bring TDD practices to the FORTRAN community. The change could be very hard, personally, I quit, since I could not make the change. I hope your organization will be successful. Enjoy a cup of fruit while maintaining FORTRAN !

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. -

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. -

Chef
Chef Infra, a powerful automation platform
Chef is an infrastructure-as-code framework that automates how servers are configured and kept in the desired state across fleets. You describe system intent in Ruby-based “recipes” and “cookbooks” made of resources (packages, files, services, users, registries, and more) that converge idempotently, so repeated runs only change what’s necessary. Its client regularly gathers system facts, evaluates policy, and enforces drift correction, which makes environments reproducible from bare metal to cloud instances and containers. Chef’s ecosystem includes roles, environments, and Policyfiles to scope configuration for different stages and teams, plus handlers and notifications for operational visibility. It integrates with secrets stores, package managers, and service managers on Linux and Windows, while custom resources let you encapsulate domain-specific logic cleanly. -

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. -
