This project is a Ruby library for defining and managing object lifecycles through states, events, and transition rules. It functions as a declarative workflow engine that enforces business logic by restricting attribute changes to predefined, valid paths within Ruby classes. The library distinguishes itself through deep integration with database persistence layers, allowing it to automatically synchronize state changes with data models, validation frameworks, and transaction management. It supports dynamic configuration, enabling the construction of lifecycle rules at runtime from external d
This is a TypeScript web application and single-page application built with Angular. It serves as a full-featured blogging platform and content management system that implements professional architectural patterns for building complex user interfaces. The project functions as a REST API client that integrates with a backend service to manage users, articles, and social interactions. It includes a markdown content renderer to display formatted articles and a system for content discovery using paginated feeds and category filters. The application covers several functional domains, including us

SimpleCov is a Ruby code coverage tool and analysis engine used to track which lines, branches, and methods of code execute during tests. It functions as a coverage threshold enforcer and test suite aggregator, recording execution data to identify untested areas of an application. The tool distinguishes itself through the ability to merge coverage results from parallel worker processes and subprocesses into a single unified report. It supports baseline comparison to detect coverage regressions and can gather data from code executed via dynamic evaluation methods, such as those used in templat
The participatory democracy framework. A generator and multiple gems made with Ruby on Rails
Diaspora is a federated social networking platform that allows users to run and manage self-hosted community servers, known as pods. It operates as a distributed network where independent server nodes exchange content and users using open protocols and standardized communication schemas. The platform is distinguished by its focus on decentralized identity management and privacy-preserving communication. It includes a privacy-focused media proxy that routes external assets through a local server to protect user identity and supports cross-instance account migration, allowing users to move thei
Discourse is an open-source forum engine designed to facilitate long-form threaded conversations and community management. Built as a server-side application, it provides a structured, category-based interface for interactive online communities, supporting user authentication, moderation, and real-time content delivery. The platform utilizes a relational database to manage complex relationships between users, topics, and site settings. The application distinguishes itself through a modular architecture that allows for custom plugins and themes, enabling the adaptation of discussion spaces to
Pundit is a Ruby authorization framework that implements policy-based access control. It maps domain models to dedicated logic classes that determine whether a user is permitted to perform specific actions on data objects. The framework utilizes plain Ruby objects to decouple authorization logic from the model. It includes mechanisms for data query scoping to filter record collections based on user permissions, as well as attribute-level permission control to restrict which specific model fields a user can modify. The system provides tools for authorization coverage verification to ensure se
EventMachine is a reactor-pattern network framework for Ruby that provides an asynchronous I/O library for performing non-blocking network and file operations. It functions as a network server framework used to build scalable TCP and UDP servers and clients that process multiple simultaneous requests. The framework implements a concurrency model that dispatches network events to registered handlers using a single-threaded event loop. This approach allows for the management of high-concurrency network connections without the overhead of multi-threaded programming. The library covers the devel
Markup is a tool for converting various documentation formats and manual pages into structured HTML. It functions as a rendering engine selector and converter that transforms raw markup files into web-ready output using a pluggable pipeline. The system identifies the appropriate rendering engine by utilizing file extensions or analyzing document content through pattern-based language detection. This allows the pipeline to handle documents where file extensions are missing or ambiguous. The project covers a broad range of content transformation, including the conversion of traditional man pag
A statesmanlike state machine library.
Parallel is a Ruby library and multi-process execution framework designed to accelerate CPU-intensive operations. It functions as a parallel job orchestrator and concurrent task runner that enables the execution of code across multiple processes or threads. The project distinguishes itself through secure inter-process communication, utilizing signed data serialization to prevent the injection of forged payloads between parent and child processes. It further differentiates its worker management by assigning unique identifiers to individual processes to prevent collisions when accessing shared
This project is a public community data API that provides a RESTful interface for accessing real-time discussions and metadata. It serves as a JSON data provider, offering structured community information for use in third-party client and server applications. The interface enables the retrieval of public items, stories, and comments, as well as public account information for specific users. It provides capabilities for fetching filtered lists of stories based on ranking or novelty and allows for the discovery of recent items to track new content updates. The system covers a broad range of da
All sorts of useful information about every country packaged as convenient little country objects. It includes data from ISO 3166 (countries and states/subdivisions ), ISO 4217 (currency), and E.164 (phone numbers).
This library provides a framework for defining finite state machines within Ruby classes to manage complex object lifecycles. It functions as a declarative workflow engine, allowing developers to model object states, events, and transitions through a readable domain-specific language. By integrating directly with database persistence layers, the framework ensures that state changes are synchronized with storage records while maintaining data integrity through transaction management and row locking. The library distinguishes itself by enforcing strict business rules through conditional transit
