Tested guides for people who ship and operate software
Practical guides for AI-assisted development, Cloudflare, VPS infrastructure, automation, deployment and modern software engineering.
Add Claude Code to a TypeScript repo you already have: a CLAUDE.md that matches your real build, permission rules that block dangerous commands, and a typecheck loop the agent runs itself.
SSH hardening, a default-deny firewall, and the fix for the problem that catches almost everyone — Docker publishing container ports straight past UFW into the public internet.
A production n8n install on Ubuntu 24.04 using Docker Compose, PostgreSQL and Caddy for automatic TLS — with the encryption key, webhook URL and backup steps most quickstarts leave out.
A hosted headless commerce backend hides its ceiling behind feature tables: two official pricing pages disagree by 10x, GraphQL checkout support stays alpha, and there is no self-hosting path.
Feature tables and vendor demos hide a five-year release gap, a paywalled marketplace module and unresolved 2026 security reports that decide the build-vs-skip call.
Shopware's feature table hides where the MIT core stops and paid tiers start: verified pricing, architecture, AI-readiness scores and a five-question PoC checklist.
Feature tables hide the real question: does GraphQL, MCP and multi-channel design add up to agent readiness. Verified pricing, architecture trade-offs and a PoC checklist answer it.
PrestaShop's core is free, but its module marketplace and an admittedly incomplete Symfony rewrite decide the platform's real total cost of ownership.
A B2B platform's feature table hides which account, workflow and quoting features are free versus enterprise-only, and what the enterprise licence actually costs.
Using AI models and AI-assisted tooling inside real codebases: Claude Code, Codex, Cursor, prompt engineering and Model Context Protocol.
Workers, Pages, R2, DNS, tunnels, caching and edge security on the Cloudflare platform.
Provisioning, hardening and operating Ubuntu servers: users, firewalls, SSH, systemd and day-two administration.
More in VPSSelf-hosting n8n and building dependable automation workflows that integrate real business systems.
Ordered sequences that take a subject from first setup to running it in production.
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.
8 lessons
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.
3 lessons
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.
2 lessons
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.
