Practical notes on OpenClaw infrastructure, automation, software, and the decisions hiding underneath them.
A headless Chromium spider, one SQLite file per crawl, an LLM that reads dealer pages until hand-written extractors earn the job, an event store keyed by VIN, and a negotiator that calls the dealership for you. With six screenshots and three architecture diagrams.

Read the article →How this site’s newsletter works: signup, a signed confirmation link, one email per new post, and one-click unsubscribe headers, all on one SQLite table. With the CASL and Gmail bulk-sender rules it has to satisfy.
Read the article →Rocket.Chat’s REST rate limiter allows 10 calls a minute per endpoint, shared by everyone behind one IP. How a polling integration failed every visitor at once, and the Node.js websocket client that replaced it.
Read the article →A single append-only events table in SQLite runs a real business. The schema, the projections, the background jobs that replaced a queue, and the outage that taught me where SQLite’s limits actually are.
Read the article →A focused guide for home servers and other bring-your-own installations: connect Xero with one revocable gateway key, keep OAuth tokens off the claw, and put approval boundaries around bookkeeping automation.
Read the guide →How the CargoPax promo was made with the Codex CLI: no video editor, one script that draws every frame as SVG and hands them to ffmpeg, and a re-render whenever the copy changes. The video is embedded.
Read the article →How the Nestled walkthrough video was made: the narration written first, one audio clip per line from OpenAI’s speech API, Playwright recording the real site against seed data, and ffmpeg fitting the picture to the voice. Captions came free.
Read the article →The Xero gateway is live for OpenClaw: one click from your account, one key per worker, tokens held and rotated by 8Examples, every call audited. How it is built, how to switch it on for a worker you already have, and what a month-end reconciliation looks like over Telegram.
Read the article →A stuck Xero developer flow shows why green infrastructure checks are not enough: test complete user journeys before release, then verify the critical ones in production on a regular heartbeat.
Read the article →The two-repository deployment pipeline behind Inventory Shopify: parallel Docker builds on GitHub-hosted runners, GHCR as the handoff, repository dispatch as the release signal, and a labelled self-hosted runner replacing the production containers on my own server.
Read the walkthrough →Building a small, typed Vue 3 v-copy directive, using it several times on one page, and testing both its lifecycle details and the real browser Clipboard API with Jest and Playwright.
Read the walkthrough →Connecting a self-hosted OpenClaw agent to the phone network so it can make outbound calls, keep its tools and context, and bring a human into a workflow when judgment is needed.
Read the walkthrough →Turning a team convention into a custom Roslyn analyzer. SMART001 requires that any C# property ending in Enumeration be typed as a Smart Enum, and it ships as an error, so a violation breaks the build instead of adding a warning nobody reads.
Read the walkthrough →How a technical article goes from an AI-assisted draft to a deployed page: a coding agent working inside the real repository, the project’s own Playwright suite keeping it honest, and the GitHub Actions and Docker pipeline that was already there doing the publishing.
Read the walkthrough →My iPad Pro development setup: rather than forcing a development stack into iPadOS, the iPad is a thin client onto real machines over a VPN and remote desktop, supervising AI coding agents that do the typing. Plus the OpenClaw capacity math and giving an agent a phone number.
Read the walkthrough →Three repositories that file every C#, JavaScript, and TypeScript feature under the version that introduced it, each one proven by a test that actually runs. How the toolchain is made the referee, and what came out of writing all three in unattended 30-minute terminal sessions.
Read the walkthrough →A plain .http file in Rider replaced Postman, Fiddler, Thunder Client, and curl for manually invoking APIs. Environments, automatic JWT acquisition, raw responses, and the same requests against local and production, demonstrated on an event-sourced .NET API.
