Monaco Editor
A browser based code editor
Monaco Editor is the rich, browser-based code editor that powers Visual Studio Code, providing advanced editing capabilities as a standalone embeddable library for web applications. Models are at the heart of Monaco editor. It's what you interact with when managing content. A model represents a file that has been opened. This could represent a file that exists on a file system, but it doesn't have to. For example, the model holds the text content, determines the language of the content, and tracks the edit history of the content. An editor is a user facing view of the model. This is what gets attached to the DOM and what your users see visually. Typical editor operations are displaying a model, managing the view state, or executing actions or commands. -

ToaruOS
Hobby operating system, bootloader, kernel, drivers, C library
ToaruOS is a "complete" operating system for x86-64 PCs and experimental support for ARMv8. While many independent, hobby, and research OSes aim to experiment with new designs, ToaruOS is intended as an educational resource, providing a representative microcosm of functionality found in major desktop operating systems. The OS includes a kernel, bootloader, dynamic shared object linker, C standard library, its own composited windowing system, a dynamic bytecode-compiled programming language, advanced code editor, and dozens of other utilities and example applications. There are no external runtime dependencies and all required source code, totaling roughly 100k lines of (primarily) C, is included in this repository, save for Kuroko, which lives separately. Through out the project, ToaruOS has also attracted quite a few beginner OS developers who have tried to use it as a reference. -

It allows developers to transform, filter, and move code between repositories while maintaining a consistent source of truth. Copybara is particularly useful in workflows where projects maintain both confidential (internal) and public (open source) repositories, enabling controlled synchronization and contribution management between them. The tool supports advanced transformations—such as file relocation, content replacement, and metadata adjustments—defined declaratively in configuration files. It operates in a stateless manner, storing synchronization state within commit metadata to ensure reproducibility and collaboration among multiple users. Copybara currently supports Git repositories (with experimental Mercurial support) and can be integrated with CI/CD systems or run manually. -

The project supports multiple providers such as Ollama, DeepSeek, and Mistral, enabling flexibility between local and remote inference depending on user needs. It integrates with editors like Neovim, VS Code, Zed, and Emacs by redirecting Copilot traffic through a configurable proxy layer. The system allows customization of parameters such as context size, token prediction limits, and prompt templates, which gives developers granular control over how completions are generated. It also supports secure connections through TLS configuration and can be deployed as a background service for continuous availability. -

UIkit
Lightweight modular front-end framework for developing web interfaces
A lightweight and modular front-end framework for developing fast and powerful web interfaces. UIkit will work on pretty much any modern browser. Using UIkit works best if you have a solid code editor, for example Sublime Text or Atom. To be even more efficient, we recommend that you install one of the autocomplete plugins for your favorite IDE or code editor. This saves a lot of time, as you won't have to look up and type all UIkit classes and markup. To use UIkit's CSS and JavaScript, include the files in your own HTML and then create the markup of any of the components. When you have installed UIkit with Less sources, you can compile it and add your own custom theme. Less is the language that the UIkit styles are written in. This allows you to include customizations in the build process, rather than manually overwriting a lot of CSS rules by hand. -
