GitHub Actions CI/CD to a VPS with Automatic Rollback
Safe GitHub Actions deploys to a VPS: run tests, SSH in with a deploy-only key, build a fresh release, health-check it and roll back automatically on failure. Most "deploy to VPS with GitHub Actions" tutorials stop at ssh server "git pull && npm run build && pm2 restart" . That works until the day

OpenClaw is an open-source AI agent that acts for you from chat apps. Run it on its own VPS, keep the gateway on loopback, and reach it over SSH or Tailscale.

Bash Scripting for DevOps: 8 Scripts I Use on Servers
Bash scripting for DevOps means small, strict scripts that automate deploys, checks and alerts. Start each with set -euo pipefail and lint it with shellcheck. When I first wrote about shell scripting here, I showed "Hello, World" and a loop that counts to five. That's how everyone learns, but it

What Is DevOps? A Practical Guide for Small Teams
DevOps is how a team ships software often and safely: automated tests, one-click deploys, monitoring and fast rollback, owned by the people who build it.
