The Economics of Web Scraping: How Consultancies Price Data Extraction and Manage Scope Creep

Building a Universal Drafts System in a VS Code Extension — Part 1: Types & Storage

How I designed the Draft type, DraftsService, and the save/upsert flow that powers DotShare v3.2.5 — with full TypeScript code and the decisions behind every choice. Before v3.2.5, DotShare had zero persistence. Write a 2,000-word Dev.to article in the WebView, switch tabs to check something, come back — gone. Reset. Empty form. So I built a drafts system. This is Part 1: how I modeled...

Google Cloud NEXT '26 Just Changed How I Think About Real-Time Clinical Decision Support

This is a submission for the Google Cloud NEXT Writing Challenge I've been obsessing over Clinical Decision Support (CDS) systems for years. And if you've ever built one — a real one, one that has to watch over a patient in the ICU at 2 AM, react to a blood pressure crash, cross-reference incoming lab results, parse a nursing note written in shorthand, and still deliver an actionable alert be...

Model Output Is Not Authority: Action Assurance for AI Agents

Model Output Is Not Authority: Action Assurance for AI Agents AI agent security is not only about making the model safer. That statement may sound obvious, but it becomes important once an AI system can do more than generate text. When an AI agent can call tools, access internal systems, update records, send messages, initiate workflows, or delegate tasks to other agents, the security...

AI Coding Tools in Practice: What a 25-40% Productivity Gain Really Looks Like

Our JavaScript team tested AI-assisted development on production code. Here's what we measured, what surprised us, and why we think the real gain is 25-40% -- not the 10x you keep hearing about. Over the past year, AI coding tools have been surrounded by bold claims: "Develop twice as fast." "10x developer productivity." "Code that practically writes itself." We decided to test these claims o...

We probed 20,338 x402 endpoints. 161 are agent honeypots. x402 lets HTTP servers charge per request via cryptographic micropayments. It's the rail under agentic.market, a directory of paid endpoints AI agents can call autonomously. The catalog has grown to 20,338 endpoints across 516 services in a few months. I ran a probe over every one of them. The results are bad news for any agent that picks ...

I built a validated alternative to CLAUDE.md/AGENTS.MD — meet GUIDE.md

If you've used Claude, Cursor, or Copilot on a real project, you've probably created a CLAUDE.md or agents.md file — a markdown file that tells the AI about your codebase. The problem is there's nothing stopping that file from being wrong. You declare language: typescript but the project is now Python. You list entry points that no longer exist. Your version numbers drift from what's actually in...
