Wiring OpenCV into React Native used to mean a vendored framework on iOS, JNI/CMake on Android, and a simulator arch hack. Building my panorama-stitching Expo module, it became one dependency line per platform.

Apple wants every app to expose its features through App Intents so Siri can call them. The technical work is fine. The unwritten part of the contract is what should make every developer pause.

OpenClaw got the hype and an OpenAI acqui-hire; Nous Research's Hermes is quietly building the same idea in the open. A look at two real local-first agents and why I bet on the open one.

Running Qwen, Llama, and DeepSeek locally on Apple Silicon for coding, and the math on when it's actually cheaper than Claude or GPT.

How AI search ate the world's largest programming community and why nothing replaced what we lost.

Vercel is wonderful until your free tier ends and your bill is $400 for a side project with 12,000 monthly users. The math, the Hetzner vs Hostinger comparison, and when each one actually wins.

The Expo Modules API replaced 80% of the reasons you used to "eject." Swift and Kotlin DSLs, type-safe TS bindings, no codegen YAML. Here's what writing one actually feels like.

The New Architecture is default. Bridgeless mode shipped. Hermes is the only engine that matters. Here's what it actually means for shipping apps in 2026.
