Skir – like Protocol Buffer but better

In plain words

Skir is a data serialization tool designed as an alternative to Protocol Buffers for teams working across multiple programming languages. It centralizes all configuration in a single YAML file and can be initialized quickly via command line. The tool is built for development teams that need to exchange structured data between different language environments and seek a simpler configuration approach than traditional protobuf setups.

  SKI is a on-device voice coding application, which can be used with any agents that supports skill, such as Claude Code, Codex or Hermes. It transcribes your voice (which you can optionally review and edit) and send it to the connected agent. The agent then completes the task, and uses the skill to talk about the updates of the project or a summary or a query using voice. This runs completely on-device. Free. No subscription. Available on both Mac (notch and pill) and Windows (pill widget) It can also be sent to meetings with the intelligence of the connected project to participate actively…

  I built Skim because I was super dissatisfied with all existing Windows clients. I mean, it's not a rocket science, there should be some lightweight modern solution, isn't it? So I decided to create a client that just, you know, MAKES SENSE and has design younger than dinosaurs. Key points: * Obsessed with installer size: it should be under 5Mb. * BYOK AI. Cowriter, agentic search, summarization and other AI stuff is powered by your own key for Anthropic/Openrouter, or you can connect your own OpenAI-compatible server (including local) * No bloat. It should be as contextual as possible:…

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
