A repeatable way to measure end‑to‑end input latency: Arduino HID input + phototransistor sensor to time screen luminance changes, comparing Wayland, X11, XWayland, and Windows.
A homelab pattern for dynamic IPs: VPN for access, AdGuard Home as tailnet DNS, and Caddy reverse proxy with automatic HTTPS using DNS challenge plugins.
Build a low power TrueNAS SCALE NAS on Intel Alder Lake: component picks, BIOS tweaks for deep C-states, and real idle power results with ZFS mirrors.
Speed up Frigate NVR with an Intel iGPU: Proxmox PCI passthrough, OpenVINO object detection with YOLO‑NAS, and ffmpeg hardware acceleration (QSV/VAAPI).
How to build a contact form for a static Hugo site: self-host a minimal Go backend that validates input, checks Friendly Captcha, sends SMTP mail, and sits behind an nginx reverse proxy.
What runs my home infrastructure: a 6W-idle Proxmox server, TrueNAS storage, Frigate NVR, OpenWrt networking, and Zigbee-based smart home.
A personal tech nostalgia story from growing up in the 90s: flea market finds, a VTech learning computer, and the first experiments with a tiny BASIC interpreter.
