Xlibe – A serverless Xlib (X11) compatibility layer for Haiku

In plain words

Xlibe is a serverless Xlib compatibility layer that brings X11 application support to Haiku OS. It implements core Xlib APIs without advanced features like XRender or GLX, enabling sophisticated applications such as Cairo and GTK to run on the platform. The layer has enabled GTK3, GIMP, and Inkscape to function on Haiku, though cross-program interaction remains limited and some X11 features cannot be fully replicated.

In the maker’s words, at launch

Hello HN, While there are some projects that implement partial versions of Xlib APIs on non-X11 platforms for compatibility (most notably, Tk), I don't know of any others sophisticated enough to run Cairo and GTK applications (albeit with a few hacks). So I figured this might be technically interesting. As of now it…

  WASM-powered codespaces for Python notebooks on GitHub2025 · docs.marimo.io · ▲204

  Hi HN! Last year, we shared marimo [1], an open-source reactive notebook for Python with support for execution through WebAssembly [2]. We wanted to share something new: you can now run marimo and Jupyter notebooks directly from GitHub in a Wasm-powered, codespace-like environment. What makes this powerful is that we mount the GitHub repository's contents as a filesystem in the notebook, making it really easy to share notebooks with data. All you need to do is prepend 'marimo.app' to any Python notebook on GitHub. Some examples: - Jupyter Notebook:…

  Lyceum – An MMO game built with Zig and Erlang2024 · github.com · ▲148

  Hey HN, this is a small project myself and closer friends have been building on our free time (https://github.com/Dr-Nekoma/lyceum), it finally reached 0.1.0, we are open to feedback! The original idea was to experiment with Zig + Raylib, eventually we wrote a small server in Erlang as well. We started by first interacting with Erlang via its C bindings, but this eventually led to some of us to prototyping our own tooling to better integrate Zig types with Erlang, we called such tool "zerl" as its avaliable here…

  Marimo VS Code extension – Python notebooks built on LSP and uvNov 2025 · github.com · ▲65

  Hi HN! We're excited to release our VS Code/Cursor extension for marimo [1], an open-source, reactive Python notebook. This extension provides a native experience for working with marimo notebooks, a long-requested feature that we’ve worked hard to get right. An LSP-first architecture The core of our extension is a marimo notebook language server (marimo-lsp [2]). As far as we know, it’s the first notebook runtime to take this approach. The Language Server Protocol (LSP) [3] offers a small but important set of notebook-related capabilities that we use for document and kernel syncing;…

  Warp, a Rust-based terminal▲946

  Hi HN community, I’m Zach, founder and CEO of Warp, and am excited to show you Warp, a fast Rust-based terminal that’s easy to use and built for teams. As of today, Warp is in public beta and any Mac user can download it. It works with bash, zsh, and fish. The terminal’s teletype-like interface has made it hard for the CLI to thrive. After 20 years of programming, I still find it hard to copy a command’s output; I always forget how to use `tar`; and I always have to relearn how to move my cursor. To fix fundamental accessibility issues, I believe we need to start innovating on the terminal,…
