    Open Brush

    Open Brush

    Open Brush is the community led successor to Tilt Brush!

    ...Open Brush is a derivative made from the open source code of Tilt Brush, a room-scale 3D-painting virtual-reality application available from Google, originally developed by Skillman & Hackett. OpenBrush strives to be an open source tool to help everyone create their own art. We believe in the preservation of art, and the freedom of artists. At our core, we are community led and driven, and while there may be a small core team behind OpenBrush, it would not be possible without our community.

    Vulkan.jl

    Vulkan.jl

    Using Vulkan from Julia

    ...It exposes abstractions over the underlying C interface, primarily geared toward developers looking for a more natural way to work with Vulkan with minimal overhead. It builds upon the core API provided by VulkanCore.jl. Because Vulkan is originally a C specification, interfacing with it requires some knowledge before correctly being used from Julia. This package acts as an abstraction layer, so that you don't need to know how to properly call a C library, while still retaining full functionality. The wrapper is generated directly from the Vulkan Specification.

Its core functionality is surprisingly practical beneath the joke: when triggered, it sends a keyboard interrupt signal (Ctrl+C) to halt the current AI process, effectively giving developers a quick way to stop unresponsive or slow-running tasks. In addition to the interrupt, the tool also delivers randomized “encouraging” or humorous messages, blending utility with personality and making the experience more entertaining.

    Bash is all you need, write a claude code with only 16 line code

    Learn Claude Code is an educational repository that teaches how modern AI coding agents work by walking learners through a sequence of progressively more complex agent implementations, starting with a minimal Bash-based agent and culminating in agents with explicit planning, subagents, and skills. It emphasizes a hands-on learning path where each version (from v0 to v4) adds conceptual building blocks like the core agent loop, todo planning, task decomposition, and domain knowledge skills, illuminating the patterns behind what makes a true AI agent tick. The goal is to demystify agent architectures like Claude Code by having learners build simplified versions themselves and observe how tools, memory management, planning constraints, and context isolation contribute to reliable agent behavior. ...
