The Common Roadblocks for AI Storytelling

Roadblocks in AI Storytelling and How Emstrata Solves Them By The Emstrata Team AI storytelling systems face a consistent set of technical and philosophical problems that undermine their ability to create coherent, engaging collaborative narratives. These aren't minor bugs or edge cases but fundamental architectural challenges. Understanding these roadblocks is essential because they determine whether systems enhance human creativity or frustrate it. Redescription occurs when an AI inconsisten

Authentication with node:http and better-auth

Sometimes I just want a Node.js server that works without pulling in Express or any other heavy frameworks. This is a simple pattern I’ve been using for handling authentication with node:http and a library called better-auth. I’m writing this down for future me, so I don’t have to remember all the small details. Hope this helps you or at least shows you something new. No frameworks: I don’t want to add Express/Koa just for a few endpoints. Minimal dependencies: better-auth handles the auth logic

The Most Underrated Tool in Your Dev Toolbox: Pre-Commit Hooks (Yes, That 20-Year-Old Git Feature)

Look, I've been slinging code for longer than I care to admit, and one thing never fails to blow my mind: teams dropping serious cash on massive CI pipelines just to catch the dumbest mistakes imaginable. We're out here pushing broken code on purpose, waiting for GitHub Actions or some cloud runner to slap our wrists and say "bad developer." It's like paying a bouncer to tell you your shoes are untied after you've already tripped down the stairs. There's a better way. A way that's instant, local

When .cursorrules Fails: Why AI Ignores Your Rules (And How to Fix It)

You set up .cursorrules. You specified TypeScript strict mode. The AI still generates any types. Configuration isn't enforcement. This is Part 2 of my .cursorrules guide. The first article covered setup. This one covers what to do when it doesn't work. Three main reasons: Your .cursorrules says one thing. Your codebase does another. # .cursorrules Use named exports only. No default exports. Meanwhile in your codebase: // src/components/Button.tsx (already in codebase) export default function Bu

What Developers Can Learn From Exchange Security Models

In the world of crypto, security isn’t just a best practice — it’s a fundamental requirement. Exchanges handle vast amounts of digital assets and sensitive user data, making them prime targets for cyberattacks. For developers, examining how these platforms structure their security can offer actionable lessons applicable to any high‑risk application. 1. Defense in Depth Takeaway: Never rely on just one layer of defense. Multiple overlapping protections dramatically reduce attack surface. 2. Asset

What the AWS us-east-1 Outage Taught Me About Building Resilient Systems

AWS us-east-1 will go down again. When it does, will your system survive? This past weekend, I built a system designed to survive it. After 8 years building subscription infrastructure at Surfline—processing payments through Stripe, Apple, and Google Play—I've learned that the question isn't whether your cloud provider will fail. It's whether your architecture degrades gracefully when it does. I spent 4 hours implementing three reliability patterns sourced directly from the AWS Builders' Library
