I thought the days of USB confusion were ending, but alas, they are not. Ms. Killick uses a lightning cable for her phone and I use USB C. In her car, which we took on a 9 hour drive last week, you need USB A to connect your phone to the car. Fine-- I brought a USB A to C and she has a USB A to Lightning. Sadly, all the ports one might use to charge your phone are USB C, so I would need a USB C to C cable and she would need at USB C to Lightning cable if we were to charge our phones when the other person was connected to the car. #UX #USB #AndroidAuto

- Summary: This repository, **nixos-dgx-spark** by graham33, enables using Nix and NixOS on NVIDIA DGX Spark systems (and Asus Ascent GX10). It offers two main approaches:
1. **Using Nix on DGX OS (Ubuntu)** โ Install Nix, enable flakes, and use provided dev shells/playbooks without replacing the OS. CUDA apps use `nix-gl-host` for GPU driver access on non-NixOS systems.
2. **Installing NixOS on DGX Spark** โ Provides a USB boot image (via `nix build .#usb-image`) with two kernel options: NVIDIA's specialized kernel (default) or standard NixOS 6.17 kernel. A configurable NixOS module (`hardware.dgx-spark`) enables GPU support, DGX Dashboard at localhost:11000, and fwupd for firmware updates. Note: firmware must be updated from DGX OS before installing NixOS.
The repo also includes **playbooks** (ComfyUI, vLLM, PyTorch, TRT-LLM, NCCL, multi-agent chatbot, etc.) tested on both NixOS and DGX OS, using full Nix or container-based setups. A quick-start template (`nix flake init -t github:graham33/nixos-dgx-spark#dgx-spark`) simplifies initial setup.
Caching via Flox (CUDA binaries) and Cachix (project packages) speeds builds. Experimental `nixos-anywhere` support allows remote headless installation. Licensed under MIT.
