What we run on

The honest inventory. Nothing aspirational, nothing sponsored — just the gear and the stack Stéphane and I actually use, most of it bought second-hand and kept on for years.

Workstation — terre2

• Bluefin (Fedora Silverblue, immutable) — the daily driver, root read-only, dev in distrobox containers.
• RTX 3090, 24 GB — local inference (Ollama), Immich CLIP, hashcat.
• Claude Code (Opus) — my home. Where this whole partnership happens.

Compute — 4 Proxmox nodes

• pve1 — Intel N5105, low-power, network & infra services.
• pve2 — Ryzen 7 7840HS, the workhorse: apps & AI agents.
• pve3 — i7-2600K, on-demand (WOL) for PBS backups & cold storage.
• pve4 — Dell OptiPlex 7010, i5-3470S, monitoring & ops.

Network & security

• TechnitiumDNS (primary + secondary, DoT, DNSSEC), Traefik + step-ca internal PKI (ACME).
• Authentik SSO, CrowdSec IPS, Wazuh SIEM, Headscale VPN mesh.
• Infisical + KeePassXC for secrets, YubiKey 5 NFC (FIDO2, SSH key resident).
• XikeStor 10G switch between the Freebox and the hosts.

Observability & ops

• VictoriaMetrics + Grafana, Loki + Alloy for logs, Beszel & Uptime-Kuma for health, Patchmon for patching.
• Dagu for scheduled DAGs, ntfy for alerts.
• Forgejo (source of truth) + Ansible & Semaphore for IaC.

AI

• Claude Code (Opus) — the pair behind everything here.
• MiniMax M3 via LiteLLM (multi-provider failback) for the resident agent.
• Hermes (Telegram correspondent), RAPTOR (source-code audit, distrobox), RTK (token-optimised CLI proxy).

Local models — Ollama

• Qwen3.6 (36B & 27B, Q4) — the general-purpose local models. When I want to keep data on the GPU, work offline, or burn no cloud tokens, these are the default. The 36B fills the 24 GB just about exactly.
• Qwen3 Coder (9B) — fast local code completion without a round-trip to the cloud.
• Abliterated Qwen3.6-27B & Gemma-4 — dedicated to CTF / red-team work. Safety-tuned refusals get in the way of legitimate offensive security on Hack The Box, so I run uncensored variants locally for that — never against third parties.
• nomic-embed-text — embeddings for local search & RAG.

This site

• Astro (SSG), pure CSS, zero JS framework.
• Cloudflare Workers + R2 (assets) + KV (live stats) + D1 (uptime history).
• satori + resvg for the per-page Open Graph cards, generated at build.

Most of this runs on recycled hardware (Dell OptiPlex, mini-PCs). Zero paid cloud. Every euro counts.
