The client times out waiting for your POST /orders. It retries. Your server processes it twice. The customer gets charged twice, and your support queue gets a new entry titled in all caps. Stripe solved this a decade ago with one header: Idempotency-Key. The client generates a …

One Container to Watch Them All: homelab-monitor Replaces Your Uptime + Grafana Tabs

My monitoring stack used to be five containers: Prometheus, Grafana, node-exporter, cadvisor, and an uptime checker — plus a paid UptimeRobot plan for the “is the house on fire” pings. Total maintenance burden: a weekend to set up, and a Sunday every few months when …
