    A backend agnostic Ruby framework for building reactive desktop apps▲92

    For a year or two I've been building a UI library with the aim of making desktop applications fun and easy to write. It is currently written in C/Ruby and uses a custom tree sitter grammar to describe templates. Features include: composable UI components, template directives, event and prop handling, slots, styles and automation capabilities baked in. One of the goals of the project is privileging easy to write custom components via a drawing API over providing a fixed set of components. At the time of this writing it should install on Windows, Mac, and Linux, but sometimes it is hard…

    Using LLMs and Embeddings to classify application errors▲65

    Hi Hacker News! We’re Vadim and Chris from Highlight.io [1]. We do web app monitoring and are working on using LLMs/embeddings to add new functionality to our error monitoring product. Given that there’s a lot of founders/engineers using LLMs in their products, we figured we’d share how we built the new functionality, their impact on our workflows, and how you can try it out. Our goal was to build two features: (1) tagging errors (e.g. deeming an error as “authentication error” or a “database error”); and (2) grouping similar errors together (e.g. two errors that have a different…

    Love Ruby but meh Daily Stand-ups (DSU)? You might like my gem:)▲15

    I love ruby and rails, but agile Daily-Stand-ups (DSU) are a pain in the butt. I have a hard time remembering what to share; what I did yesterday, one-offs I did the day before because I completely forgot. Anyhow, I created this really lovely little, but powerful ruby gem, called dsu. Currently, we're a small, but dedicated band of users who love the tool. You may love it also. If anyone wants to give it a try. Enjoy: Visit the dsu ruby gem wiki: https://github.com/gangelo/dsu/wiki Straight to rubygems.org: https://rubygems.org/gems/dsu

    RubyLLM 1.0 – A Beautiful Ruby Way to Work with AI▲30

    RubyLLM provides a unified interface to OpenAI, Anthropic, Google, and DeepSeek models with a clean, elegant API that feels like Ruby. What makes it different? Beautiful interfaces: chat = RubyLLM.chat embedding = RubyLLM.embed("Ruby is elegant") image = RubyLLM.paint("a sunset over mountains") Works with multiple providers through one API: # Start with GPT chat = RubyLLM.chat(model: 'gpt-4o-mini') # Switch to Claude? No problem chat.with_model('claude-3-5-sonnet') Streaming that makes sense: chat.ask "Write a story" do |chunk| print chunk.content # Same chunk format for all providers end…
