Microsoft restricts Claude Fable for employees over data retention concerns

Anthropic released Claude Fable, its first Mythos-class AI model, yesterday and it's already causing concerns inside Microsoft. Sources tell me that Microsoft is limiting the use of Claude Fable 5 for employees because of Anthropic's new data retention requirements. While Microsoft quickly rolled out Claude Fable 5 to its GitHub Copilot and Foundry customers, I'm […]

Architecting a Production-Ready Express + TypeScript Backend: Type Augmentation, Global Errors, and Middleware Factories

When building a personal finance tracker, data integrity and system reliability are non-negotiable. One missing try/catch block can crash your whole server, and weak types can let invalid financial payloads corrupt your database. While building the backend for my personal finance tracker, I decided to move past generic tutorials and build a bulletproof, production-grade API core using Express, TypeScript, and Zod. In this post, I’ll show you how I implemented a type-safe middleware ecosystem, leveraged TypeScript declaration merging to extend the native Request object, and eliminated repetitive try/catch boilerplate across the entire codebase. 1. The Weapon Against Boilerplate: The asyncHandler HOC Writing try/catch blocks in every single controller handler clutters code and introduces human error—it’s easy to forget to pass an error to next() . To solve this, I engineered a Higher-Order Function (HOC) factory that wraps asynchronous request handlers and automatically catches rejected promises, safely routing them into the global error handler. import { Request , Response , NextFunction , RequestHandler } from ' express ' ; export const asyncHandler = ( fn : RequestHandler ): RequestHandler => { return ( req : Request , res : Response , next : NextFunction ) => { Promise . resolve ( fn ( req , res , next )). catch ( next ); }; }; Why this matters: Reliability: Async errors always reach the centralized error middleware. Readability: Route controllers stay beautifully clean, focusing only on business logic rather than async control flow wiring. 2. TypeScript Magic: Declaration Merging & Type Augmentation When dealing with authentication tokens, request tracing ( requestId ), or custom validated payloads, developers frequently resort to casting the request as any (e.g., (req as any).userId ). This completely destroys Type Safety. Instead of fighting the compiler, I leveraged TypeScript Declaration Merging to reopen Express's internal Request interface and merge my cust

You Don't Need Another Agent. You Need a Linter.

In my last post I complained — a lot — about product managers and how they made my life hell with vibe code. PS: apologies, manager, if you're reading this — but it's true. Now, I'm not here just to complain. There were a lot of learning opportunities too, like how to handle legacy / vibe code. Because at the end of the day, both are the same: no one knows how they work, but somehow they keep working. Touching them is like defusing a bomb — you never know how your change might cascade and break the core logic. The good news is that vibe code is much simpler than legacy. AI, in all its glory, tries to write perfect-looking code — proper function names, comments, the works — not like legacy code where a single function runs 500 lines, with spaghetti names all over that make no sense and comments that are out of date. And that makes it something I can actually handle. I still don't have a perfect, step-by-step playbook — but I've got pieces. The first one. The cheapest and the oldest one. The one the industry solved decades ago and the whole "AI built my app in a day" crowd somehow forgot exists. A linter. Yes, you heard me right. A linter. ESLint. Most people who've been in this industry already know it. It's the most boring, reliable tool in the box. But in an era where the answer to every problem is "add another AI," it's worth saying out loud why the boring tool still wins. What a linter actually is If you vibe-coded your way into this world, or you're new to web dev in general and have never heard the word "lint", here's the honest version. A linter is a set of rules you add to your repo. It reads your code without running it, checks it against those rules, and flags everything that's broken, sloppy, or about to bite you in production. The detail people get wrong: it's not a grep for bad words. A real linter parses your code into a syntax tree and actually reasons about its structure — what's imported, what's called, what's reachable, what types flow where. That's
