What Rust's +simd128 Actually Changed in My WebAssembly
Rust's +simd128 produced 205 static SIMD instructions in my aggregate module, with none in the Welford loop I measured.

Launching vizcrush: Three Beliefs My Benchmarks Killed
vizcrush launched with its three loudest performance claims deleted. What measuring WASM SIMD, cross-engine WASM, and WebGPU compute actually showed.
Trajectory Lab: Scoring Structure, Not Length
I argued that the structure of an agent run beats its length. Then I built a tool to measure it, and won't ship it until the central claim is proven. Here's the build, and the gap.
Scaffolding Over Horsepower: Subagents, Skills, Hooks, and MCP
A working developer's guide to subagents, skills, hooks, and MCP. And the discipline of adding a block only when you can name the failure it prevents.
Design Before Code: A Discipline for AI-Assisted Engineering
When AI writes the code, the reasoning that produced it never exists anywhere except in a transient context window. A two-session pattern (a long Workshop to build the design, and a series of fresh Cold Reads to test it) moves accountability back where it belongs.
A Traffic-Aware BFF for Next.js: RSC Strategies and API DAGs
Picking BFF and RSC strategies by traffic, modeling API dependencies as DAGs for parallel fetching, and knowing when to extract a separate BFF service from your Next.js app.

The shift from conversational to agentic interfaces, and what it means for frontend architecture.
The LLM Agent Debugging Problem: Building Observability from Scratch
A practical guide to debugging LLM agents, with structured logging utilities, trace visualization components, and replay infrastructure you can steal for your own projects.
Building Private & Offline LLM-Powered Experiences: Client-Side AI Agents with Wasm
Learn how to build browser-based AI agents that run entirely on the client side using WebAssembly. This guide covers implementing a RAG system with local LLM inference for private, offline-capable applications.
Schema-First Forms: Zod vs TypeBox for Auto-Generated Type-Safe UIs
Stop writing forms by hand. Learn how to auto-generate type-safe forms from your validation schemas using Zod or TypeBox, and discover which approach fits your project best.
WebGL Performance Power-Up: Three.js, WASM, SIMD, and Lock-Free Concurrency
Building a 50K particle physics system that progressively layers WASM, SIMD, and Web Workers on top of Three.js. Real benchmarks, real code, real trade-offs.
We Benchmarked JS vs Wasm for WebGL: Here's What Actually Matters
A benchmark-driven comparison of JavaScript vs WebAssembly for WebGL workloads. We tested particle systems, mesh generation, and physics simulation across 1K to 1M elements. The results were not what we expected.
