Welcome to my corner of the internet. I write about technology and projects I’m working on.

lm-sensors’ nct6683 driver silently refused to bind on a Lenovo M900 Tiny running Proxmox — no error, just no fan data. The cause was a vendor/build check in the driver tripping on this box’s EC firmware, and the fix was a one-line force=1 module param made persistent.
Turning a Home Network into Real Infrastructure
A small Proxmox cluster, a managed switch or two, some IP cameras, and Home Assistant eventually stop being a pile of gadgets and start being infrastructure. Here’s how I built observability, a live topology graph, and an AI-assisted ops layer for mine — without letting anything have unsupervised write access to the network.
Building a GPS-Disciplined NTP Server on a Raspberry Pi
How a Raspberry Pi 5, a cheap u-blox GPS module, and chrony turned into a home stratum-1 time server — the wiring mistakes, the serial-port gotcha nobody documents, and the PPS upgrade that took accuracy from ±50ms to ±350ns.
Installing the NVIDIA T600 Driver with PRIME Render Offload on Debian 12 (Dell Precision 3571)
A step-by-step guide to getting a PRIME render offload setup working on a Dell Precision 3571 — Intel iGPU driving the desktop, NVIDIA T600 on demand — plus the specific mistakes that commonly break it.
