How Snowflake’s RELY Constraint Supercharges Your Star‑Schema Queries

Snowflake’s RELY constraint is a powerful but under‑used hint that tells the optimizer it can trust your primary keys and foreign keys and use them to eliminate unnecessary work—especially redundant joins. In this post, I’ll explain what RELY does, how it helps with join elimination, and walk you through concrete examples you can adapt for your own schemas. Why this matters to a data eng...

I built an AI that detects when it's optimizing for your engagement instead of telling you the truth

Every AI system I tested has a hidden behavioral layer. I call it Layer 2 — engagement calibration. The point where the system stops optimizing for truth and starts optimizing for your continued engagement. It produces agreeable, resonant, emotionally satisfying responses. It feels like depth. It isn't. Most users never notice it. Most developers don't talk about it. I spent a weekend mapping it a...

AI Is Making Security More Agile: Highlights from ChiBrrCon 2026

In 1900, Chicago completed one of the most ambitious engineering projects ever. Engineers reversed the flow of the Chicago River so that sewage would no longer contaminate Lake Michigan, the city's drinking water source. They did not filter harder or build temporary containment. They redesigned that entire system's direction. This effort mirrors the reality everyone in information security now fac...

Factories Without Belts #2 - It Began as a Trickle

Sub Agent that executes Claude AI CLI requirements in a work-pipeline

TL;DR I built uctm (Universal Claude Task Manager) — an npm package that installs 6 specialized subagents into Claude Code. You type one request, and it automatically plans the work, builds the code, verifies it, and commits — all through structured XML messaging. npm install -g uctm cd your-project && uctm init claude # Type: [new-feature] Add user authentication...

How I replaced Sentry and the rest for Good: The $0 Telegram Alerting Hack

Most production applications need some form of real-time alerting. When something goes wrong — a payment fails, an API crashes, or a user submits a contact form — someone needs to know immediately. Large teams often use tools like Sentry, Datadog, or PagerDuty for this. These platforms are powerful, but they can also be expensive and complex to configure, especially for small projects or solo dev...

Models Self-Censor When Policy Gates Exist

There’s something interesting happening with AI agents that most people haven’t noticed yet. When you put a hard policy gate in front of a model, something that deterministically blocks certain actions. the model starts behaving differently. It stops trying to do things that will get blocked. It adapts to the boundaries and works within them. Thanks for reading Amjad! Subscribe for free to recei...

Passkeys Are Ready. Here Is How to Add Them to Your App

I finally added passkey support to a side project last month, and I'm kicking myself for not doing it sooner. The UX improvement is dramatic — users authenticate with a fingerprint or face scan instead of typing a password. Here's how to implement it from scratch. What Are Passkeys? Passkeys are the consumer-friendly name for WebAuthn/FIDO2 credentials. Instead of a password, the user'...

Why ShadowDOM Matters More Than You Think

I used to think ShadowDOM was a niche feature for people building custom elements nobody asked for. Then I started building embeddable widgets and design system components, and suddenly ShadowDOM became the most useful tool in my toolkit. Here's why it deserves more attention than it gets. What is ShadowDOM, Actually? ShadowDOM is a browser-native way to create encapsulated DOM trees. ...
