    It's been closed source for a long time while I worked on it on and off as a hobby research project, but yesterday the repo was made public for the first time under the MPL 2.0 license. A feature reel showing its capabilities can be found here: https://ktstephano.github.io/rendering/stratusgfx/feature_re... A technical breakdown of a single frame can be found here: https://ktstephano.github.io/rendering/stratusgfx/frame_anal... It's still in a very beta state (bugs and instability expected), but I felt like it was a good time to make it…

    Here's a project I've been working on for a little while now. Ripl is a JS library that provides a unified API for rendering shapes on both canvas and SVG interchangeably. Over the years I've used D3 extensively to create data visualisations so I figured I'd have a go at making my own version with a slightly more modern API and stricter TypeScript support. I am aware there are already libraries that can draw to multiple contexts interchangeably, but I've added a few little niceties to Ripl that (as far as I know) some other libraries don't have such as CSS-like query selectors, DOM-like…

    repository: https://github.com/shimodateakira/VirtualStorageLibrary Hello HN, I'm excited to share a project I've been working on called VirtualStorageLibrary. It's a .NET library designed to manage in-memory tree structures, including items, directories, and symbolic links. VirtualStorageLibrary is a .NET library that operates entirely in-memory and provides a tree-structured collection. This library offers a foundation for managing hierarchical data structures, supporting items, directories, and symbolic links that encapsulate user-defined types (generic types defined…
