  • Data advanced

    How to Run PostgreSQL Securely on a VPS

    Keep the listener off the public internet, get pg_hba.conf right, require TLS for remote connections, and give the application a role that cannot drop your tables — on PostgreSQL 17 and Ubuntu 24.04.

  • DevOps intermediate

    How to Build a GitHub Actions Deployment Pipeline

    Test, build a container image, push it to GHCR and deploy it to a VPS over SSH — with the concurrency guard, environment approval and token scoping that keep the pipeline from becoming the weak point.

  • Data intermediate

    How to Run Meilisearch in Production with Docker

    A Meilisearch deployment that survives a real workload — master key handling, scoped API keys, the index settings you must set before loading data, snapshots, and what its memory usage actually means.

  • Agents intermediate

    An AI Coding Agent Workflow That Keeps Diffs Reviewable

    A working loop for running a coding agent on a real codebase — task scoping, branch isolation, tests as the contract, and the review discipline that stops unreviewed code reaching main.

  • Cloudflare advanced

    How to Run Cloudflare Tunnel in Front of Traefik

    Expose Docker services through Cloudflare with no inbound ports open — cloudflared plus Traefik, the forwarded-header setting that trips people up, and how to verify the firewall is closed.

    Self-Hosting Foundations

    Take a blank Ubuntu VPS to a server that runs containerised applications safely: firewalls that cover Docker, a real deployment, restorable backups, and a pipeline that ships changes.

    Cloudflare for Developers

    The parts of Cloudflare you use when you run your own infrastructure — DNS and proxy status, deploying to Workers, and replacing inbound firewall rules with a tunnel.

    AI-Assisted Development

    Put a coding agent to work on a codebase you already have, and keep the output reviewable — project setup, permission boundaries, task scoping and the review discipline that makes it safe to merge.

    n8n in Production

    Run self-hosted n8n as infrastructure rather than a hobby project — Postgres storage, TLS, encryption key handling, host hardening and backups that include the things a database dump misses.
