I built a free full-stack auth starter so you can skip "auth week" (Flutter + FastAPI)

Every side project I've started died a little during the same seven days: auth week. You know the drill. Login screen, register screen, forgot password. JWT access tokens, refresh tokens, where do I even store these securely? Then the Google Sign-In configuration maze — SHA-1 fingerprints, two different client IDs, the OAuth consent screen. A week of boring, error-prone work before you write a single line of your actual product. So I built the whole thing once, properly, and released it free. Fl

Your AI Agent Can Call Every API — Except Your Bank. Here's Why.

Every API you'd want an agent to call has a clean path: an API key, an OAuth dance, maybe a scoped token. Your LLM can read your calendar, file your issues, query your database. Then it hits your bank — and the door slams. It's not that bank APIs don't exist. PSD2 forced EU banks to publish them. It's that the authentication layer is built for institutions, not agents. Getting onto a bank's API as a third party requires an eIDAS QWAC + eSEAL certificate — a Qualified Website Authentication Certi

The Silent Outage: Monitoring What You Can't See

The worst kind of outage is one nobody notices. Your metrics are green. Your dashboards are fine. Your users are quietly getting a broken experience. I've been burned by three silent outages in my career. Here's how I catch them now. Frontend caching the error. Your API returned a 500. Your CDN cached it. Now all users get the cached error for 10 minutes, but your API health check passes because the CDN never re-asks. Partial feature breakage. Login works. Checkout works. The search bar silently

Python Data Model - Part 1

Leia a versão em português deste artigo aqui. Ever wondered why modifying a list inside a function changes the original list, but modifying a number doesn't? You've just run into one of the most fundamental — and most misunderstood — concepts in Python: its data model. Understanding how Python represents, identifies, and compares objects isn't just theory: it's what saves you from subtle bugs related to aliasing, incorrect comparisons, and unexpected side effects in mutable containers. In this f

Google reCAPTCHA v2 and v3 in React, Vue, or Angular, with one prop

Every time I add Google reCAPTCHA to a form I end up rewriting the same glue: load the script exactly once, register and clean up global callbacks, handle the token expiring, and remember that v2 and v3 work nothing alike. So I packaged it into three tiny libraries, one per framework, with the same API: recaptcha-react recaptcha-vue recaptcha-angular They are zero-dependency, fully typed, tested, and MIT. The part I am happiest with: you switch between v2 and v3 with a single version prop. npm i

I Added an MCP Server to NPMScan for AI Coding Agents

I Added an MCP Server to NPMScan for AI Coding Agents AI coding agents are increasingly choosing libraries, installing dependencies, and modifying package.json files. But when an agent recommends an npm package, it may rely on model knowledge, general web search, or incomplete package information. I wanted NPMScan to be available directly inside that workflow. NPMScan now has a public MCP server that allows compatible AI agents to query npm package metadata, versions, install scripts, maintain
