Installing jcode on nix/NixOS: A Practical Unofficial Guide

jcode is an open-source AI coding agent that runs as a local server and drives your editor. It's distributed as a single self-contained executable, which sounds simple, until you try to run it in a pure Nix environment: no system package manager, no Nix channels, no /usr/bin/

La Francia si fa il suo Linux di Stato con NixOS

La Francia si fa il suo Linux di Stato con NixOS

Aprile 2026. La Direction interministérielle du numérique (DINUM), l'agenzia digitale del governo francese, annuncia che lascerà Microsoft Windows per passare a NixOS, una distribuzione Linux poco conosciuta al grande pubblico. Non è un esperimento. È il primo passo di un piano che punta a migrare 2,5 milioni

sandbox-bwrap-nix: A lightweight sandbox for AI agents and experiments

If you run AI coding tools on your machine, you know the fear. What if the agent decides to rm -rf something it should not? What if it messes up your home directory, your config files, or your projects? Containers can help, but Docker and Podman are heavy. You need

NixOS is more complicated than you think but opencode fixed it

Overview A deep dive into an advanced, minimal NixOS setup using LabWC (Wayland compositor) + Noctalia Shell V5 (from Cachix, not the official NixOS repo), assisted by opencode with the DeepSeek V4 Flash model for AI-guided configuration. The result? A desktop that boots at 743 MB RAM with only 48 active

Fixing GNOME Snapshot's PipeWire segfault on NixOS and OpenCode with Deepseek V4 Flash

Fixing GNOME Snapshot's PipeWire segfault on NixOS and OpenCode with Deepseek V4 Flash

TL;DR: GNOME Snapshot segfaults (SIGSEGV 139) when the camera portal returns a PipeWire file descriptor. The portal steals the connection's fd, disconnects the client, and hands the dup to Snapshot — which then tries to re-register on a dead connection. The fix is a 50-line LD_PRELOAD shim

Can Nix Be a Better Arch Linux AUR?

Can Nix Be a Better Arch Linux AUR?

If you have used Linux for a while, you have heard the warning. The AUR will eventually run untrusted code on your machine. It is true, and it is also why people look at Nix and wonder if its flake ecosystem could do the same job more safely. The pitch

NixOS + Noctalia V5 + LabWC on Real Hardware

NixOS + Noctalia V5 + LabWC on Real Hardware

NixOS on paper is everything a Linux user could dream of, a purely declarative OS where your entire system configuration lives in a single file, reproducible down to the kernel module. In practice, it's a labyrinth of unknown unknowns, especially if you're not running GNOME or

Noctalia V5 + LabWC on NixOS

Noctalia V5 isn't released yet but you already can try it on Linux distro like Artix, Arch, NixOS. Please follow the official Noctalia documentation or copy the parts you need from my configuration.nix. The ram usage on NixOS is 366Mb for Noctalia V5 + LabWC, I also use

opencode with superpowers. It can do everything in a container with docker and nix

TL;DR: A lightweight Docker image (~223MB) that combines Nix package manager with non-root isolation, enabling AI coding assistants like OpenCode and Claude Code to install any software safely without admin privileges or home directory leaks. UPDATE: If you want a more light and mainstream approch you can use the

Vibe Coding Safely: The Ultimate Guide to AI Development with OpenCode and NixOS via docker-nixuser

In the era of AI-powered development, tools like OpenCode are revolutionizing how we write, test, and debug code. These intelligent assistants can generate code, execute commands, and even auto-correct errors, all from the comfort of your terminal. But with great power comes great responsibility. The Security Dilemma OpenCode is a

GNOME 49 Ram usage on NixOS, Chimera Linux and Manjaro

I tried GNOME 49 on Manjaro, NixOS, and Chimera, and the RAM usage varied dramatically: Manjaro used 948 MB (90 processes), Chimera used 1.12 GB (107 processes), and NixOS used 757 MB (88 processes). Of course, memory consumption depends on how many background services are running, but if you’

THE BEST OPERATING SYSTEM: LINUX vs FREEBSD vs WINDOWS

Benchmark comparing CPU performance between Linux (Ubuntu 23.10, NixOS 23.05, Chimera Linux, Clearlinux), FreeBSD 13.2, and Windows 11. Tested Firefox 118 and Brave Browser based on Chromium 118. Why? Modern operating systems shares a lot of similarities and nowdays the browser is the most used app, Firefox

NixOS Linux review, is it really the alternative to Debian and Archlinux ?

NixOS 23.05 is a really impressive Linux distro, it is stable as Debian stable and updated as Archlinux. NixOS Linux killer features * Declarative: in normal Linux distro you configure the operating system with a sequence of commands, in NixOS you describe the configuration state in a configuration.nix file.
