WebsitePublisher.ai built a 1,900-line markdown guide to keep AI on track for e-commerce builds

·1 views

WebsitePublisher.ai, a platform that uses AI assistants to build websites via MCP tools and REST APIs, has published a ~1,900-line markdown cookbook to standardize how AI agents construct e-commerce sites. The guide covers 12 steps from an empty project to a fully working online shop, spanning 14 integrations including payments, inventory, and shipping. It encodes two core security rules — browser JavaScript must never write directly to the data API, and all money, stock, and points logic must remain server-side — along with clear separation of visitor and admin authentication systems. Each documented pitfall, such as client-side order total computation and mismatched field names between cart and catalog, was discovered by the team through real debugging sessions. Users can trigger the entire build process by pasting a single pre-filled prompt into Claude, ChatGPT, or Cursor, with the AI fetching the cookbook from a CDN and following its steps in order.

Why Human Skills Still Matter in the Age of AI Automation

Developer Cesar Aguirre published a short opinion piece on DEV Community on July 6 arguing that tasks AI can complete in minutes should no longer be considered special skills. The article targets beginner and experienced developers navigating the growing influence of AI in software development. Aguirre suggests that professionals need to focus on capabilities that go beyond what AI tools can easily replicate. The piece is framed as practical advice for thriving amid the current AI hype in the tech industry.

How PostgreSQL Handles a Backend Process Crash and Why It Drops All Connections

When a PostgreSQL backend process crashes, the database engine does not isolate the failure to just that session. Because all backend processes share critical memory areas — including shared buffers, lock tables, and transaction status data — PostgreSQL cannot guarantee the integrity of those structures after a crash. As a safety measure, the postmaster immediately terminates all active connections and initiates automatic recovery before accepting new ones. A demonstration using Docker and pgbench showed that connected clients received warnings about the crash and were instructed to reconnect after recovery. This behavior is an intentional design feature of PostgreSQL, prioritizing data consistency over session continuity.

How Postgres FOR UPDATE SKIP LOCKED solves concurrent resource allocation

A developer building StashMe, a digital cloakroom management system for venues, encountered a race condition where multiple simultaneous check-ins could assign the same coat hanger to different guests. The naive SQL approach of reading then writing allowed two transactions to claim the same row before either could lock it. Postgres's FOR UPDATE SKIP LOCKED clause, available since version 9.5, resolves this by having concurrent queries skip rows already locked by other transactions rather than waiting on them. This allows multiple check-ins to proceed in parallel, each claiming a distinct free hanger with no queuing or deadlocks. The same pattern underpins popular Postgres-based job queue libraries and can be applied broadly to any system distributing finite resources under concurrent load.

Developer Learns ACME Protocol Basics After Debugging HTTPS Certificate Failures

A developer encountered repeated HTTPS certificate issuance failures while deploying an application using Caddy as a reverse proxy and Let's Encrypt for SSL certificates. Despite correct DNS records, open firewall ports, and proper Caddy configuration, certificates consistently failed to issue. The root cause turned out to be a networking problem that prevented Let's Encrypt from reaching the server during ACME domain validation — not a misconfiguration in Caddy or TLS itself. The ACME protocol requires Let's Encrypt to actively validate domain ownership by contacting the applicant's server, a detail the developer had initially overlooked. Reading ACME logs and following a structured checklist — verifying DNS, checking external port reachability, and confirming challenge responses — ultimately resolved the issue and highlighted that certificate failures often stem from underlying network problems.
