🖥️Fleet
Every physical (and one virtual) host, from
flake.nix. Each has a dedicated page under Hosts with serials, hardware, and quirks (surveyed live 2026-07-08); deploy mechanics in Architecture/NixOS.folly — primary k8s cluster
Host Role Hardware Notes Hosts/optiplex control-plane Dell OptiPlex 3050, i7-7700T disko on /dev/sdaHosts/riptide worker HP EliteDesk 800 G5 Mini, i5-9500T NVMe, working TPM 2.0 Hosts/shale worker HP EliteDesk 800 G2 DM 35W, i7-6700T ex- 800g2/rosie— same box, third name
offsite — backup k8s cluster
Host Role Hardware Notes Hosts/retrofit control-plane HP EliteDesk 800 G2 DM 65W, i7-6700T Hosts/oldschool worker HP EliteDesk 800 G3 DM 35W, i5-6500 also: docker, GitHub runner, yarr
Raspberry Pis
Host Purpose Hardware Notes Hosts/cloudpi4 utility Pi Pi 4B 4 GB still Ubuntu 22.04, not NixOS Hosts/homepi4 kiosk Pi 4B 8 GB Runbooks/Kiosk; use homepi4-wifi.lolwtf.caHosts/weatherpi4 kiosk Pi 4B 8 GB reach over Tailscale; Runbooks/Kiosk Hosts/dns DNS Pi 5 8 GB Hosts/rackpi5 rack status Pi 5 8 GB diskless — RAM image from spore (ADR/0008 Diskless netboot for rackpi5) Hosts/spore NFS/PXE boot server Pi 5 8 GB, NVMe boot-critical for rackpi5; monitored by folly Hosts/radiopi0 radio Pi Zero W unmanaged — Raspbian buster, Pirate Radio case + pHAT BEAT DAC
Offline / unplugged Pis
Host Purpose Hardware Notes Hosts/blinkypi0 blinky + CloudEvents Pi Zero W offline — Blinkt! in a Flirc case; not in the flake Hosts/eviropico enviro sensor Pico W / Pico 2 W unplugged but working — Enviro+ MicroPython, not in the flake
Cloud
Host Where Notes Hosts/oldboy GCE e2-micro (free tier) tagged gcp
Images (not hosts)
wsl,iso,gce,container,netboot, andrackpi5-ram(the pi5 RAM image) are buildable images defined alongside the hosts inflake.nix.
Reaching things
LAN hosts resolve as
<host>.lolwtf.ca; offsite and weatherpi4 require the tailnet. k8s nodes have Tailscale disabled — go through the LAN or the cluster.

One page per machine with live-surveyed hardware facts (vendor, model, serial, CPU, RAM, storage, OS — collected over SSH on 2026-07-08). blinkypi0 and eviropico are pulled forward from systems/rpi/ history (the df20515b graveyard cleanup); Fleet holds the cluster/role tables.
