The Problem: Home Automation Data Is Scattered and Unactionable The sensor data problem isn’t that you’re not collecting it — Home Assistant’s SQLite recorder captures almost everything by default. The problem is that SQLite starts choking on range queries once your history table grows past a few weeks of dense sensor data. Run EXPLAIN QUERY … Read more
Why Tailscale Becomes the Wrong Tool The Coordination Server Is the Hidden Dependency Tailscale’s WireGuard mesh is elegant, and the client software works well. The problem isn’t the protocol — it’s that the glue holding your mesh together lives on Tailscale’s servers, behind closed-source code you can’t audit or replicate. Every device auth, every key … Read more
The Monitoring Problem No SaaS Tool Solves for You Most SaaS monitoring products are built around the assumption that you’re running fleets of identical cloud VMs serving HTTP traffic. Plug in the agent, get CPU and memory graphs, call it done. That model breaks completely when your stack is an Ollama inference server hammering a … Read more
The Symptom: Intermittent 502s That Only Appear on Health-Check Traffic The maddening part of this failure mode is that your backend looks healthy by every obvious metric. You curl the pod directly, you hit the service endpoint, everything returns 200. Real user traffic flows through fine — until nginx quietly decides the upstream is down … Read more
The Problem: Every Push Runs Everything, and It’s Killing Your Feedback Loop The most expensive CI failure isn’t a flaky test — it’s running the full pipeline on a commit that changed two lines in README.md. A typical monolithic .github/workflows/ci.yml queues lint, unit tests, integration tests, Docker build, push to registry, deploy to staging, and … Read more
The Problem: Your Logs Are Noisy and Your Alerting Is Dumb Threshold-based alerting has a fundamental blind spot: it measures magnitude, not behavior. A sudden flood of HTTP 200s looks healthy to every rule you’ve probably written — no error rate spike, no latency breach, nothing trips. But if those 200s are all hitting /api/export … Read more
Why the Default NPM Config Leaves Performance on the Table Nginx Proxy Manager ships with one goal: get a reverse proxy with Let’s Encrypt certs running in under ten minutes. It delivers on that. What it doesn’t deliver is a config that holds up under anything resembling real traffic. The defaults reflect shared-hosting assumptions — … Read more
The Problem: Thirty Services, Zero Visibility The moment you cross about a dozen self-hosted services, browser bookmarks stop working as an ops strategy. You end up with a mental map that looks something like this: Ollama is on :11434, n8n is on :5678, Grafana on :3000, Portainer on :9000, your WordPress instance somewhere behind an … Read more
The Problem: Per-Node Chaos Without a Collection Strategy The failure mode nobody talks about until it’s happening in production: every pod opens a direct gRPC connection to your Tempo or Loki ingest endpoint, and the backend starts dropping spans not because it’s overloaded on CPU, but because it hits its concurrent connection limit. gRPC connections … Read more
TL;DR: Which One Should You Run ## TL;DR: Which One Should You Run **Bind9** if you want static zone files, minimal moving parts, and you’re comfortable editing text and reloading a daemon. **PowerDNS** if you need an HTTP API, want zones stored in a database, or are building any kind of automation around DNS record … Read more
