    Hi HN, I’m excited to share Spot, a simple, cross-platform, React-like GUI library for Go. It is just a few days old and has lots of missing features but I'm happy with the results so far, and looking for some design feedback. Spot is designed to be easy to use and provide a consistent API across different platforms (mainly Mac & Linux). It’s inspired by React, but written in Go, aiming to combine the best of both worlds: the easy tooling & performance of Go with a modern, reactive approach to UI development. Key features: - Cross-platform: Leveraging FLTK[1] & Cocoa[2], Spot works on Mac,…

    Hey Everyone! Ron here, part of the NixOS Foundation and building Flox. Just coming out of this years NixCon and pretty excited to show hn below :) As of today, NVIDIA officially recognizes Canonical, SUSE, CIQ, and Nix—via Flox—as supported distributors for CUDA. Full blog - https://developer.nvidia.com/blog/developers-can-now-get-cud... This is a huge win for the Nix community. For years, CUDA on Nix was possible but painful—builds could take hours, and redistributing prebuilt binaries was blocked by NVIDIA's licensing requirements. NVIDIA's growing engagement with key…

    Not sure if I would post this for the last day of #marchintosh OR wait for tomorrow the 1st of April. Both apply equally. Anyway, here's a pet project of mine, I made it as a glued on for another pet project of mine, but it developed a life of it's own now and can soar skyward toward success, fame, and glory.

    Multitui▲126

    I made Multitui to control the sandbox of coding agents easily without changing my dev environment (no special container or VM). There's no configuration required in your local dev environment... just launch ClaudeCode.app instead of claude in your general terminal. Containers and VMs can be useful, but I always have a bunch of projects going and those solutions feel heavy. Multitui creates single-purpose native macOS apps for any terminal app, with optional sandbox. It uses the built-in macOS sandbox-exec along with log monitoring to give you an easy UI to manage rules, see what's being…

    Hello HN! I want to show you MyNixOS.com - a website I've been working on this year to make it easy to create and share Nix and NixOS configurations. Nix is a powerful tool to deploy software in a reproducible way, and with NixOS you can control your whole operating system through a declarative configuration. Starting out with Nix was exciting, but it definitely had a challenging learning curve. This made me start building a website focused on making it easier to create and share Nix flakes, which are the core unit of software deployment in Nix. Using the website, you can create flakes…
