SPICE + Claude Code + Oscilloscope: When the Agent Touches the Physical World

Circuit simulation, real signal capture, and automatic verification with a chained LLM. What happens when reality doesn't match the simulation — and the agent has to decide what to do about it.

US v. Heppner: Your AI Chat Has No Legal Privilege and Almost Nobody Knows It

A federal ruling just established that AI chats carry no attorney-client privilege. I'd asked Claude whether a contract clause could bite me. Now I'm reading that ruling and processing what it means for anyone using these tools for things that actually matter.

What They Learned Building a Rust Runtime for TypeScript — and What I Can't See Objectively

I've burned myself with Rust and spent posts deep in TypeScript patterns. I'm the worst possible person to be objective here. I read every line anyway — and found three design decisions I think are wrong, and one that's genuinely brilliant.

Project Glasswing: What AI Doesn't Tell You When It Writes Your Code

Glasswing hit a nerve I've had for a while. We deploy with AI, generate code with AI, and the attack surface grew in ways we haven't fully mapped yet. Here's what's concrete: what I changed in my pipeline and what you should change in yours.

MegaTrain: Training 100B+ Parameter LLMs on a Single GPU (And Why I Had to Close My Laptop)

I saw the title and figured it was clickbait. I sat down, read the paper, and had to get up and walk around. MegaTrain proposes training 100B+ parameter models on a single GPU in full precision. I won't use it tomorrow. But it shifts who can do what — and that matters to me.

Scion: The Agent Orchestration Testbed Google Just Open-Sourced

Google open-sourced Scion, a testbed for orchestrating AI agents. I dug into it alongside Freestyle (sandboxes) and finally understood what each one actually does — and I have a take on where this is all going that I haven't seen anywhere else.

Sandboxes for Coding Agents: What Freestyle Is and Why I Care

When I started using coding agents on real projects, my biggest fear wasn't that they'd write bad code — it was that they'd execute things on my machine without me understanding what. Freestyle hit HN with 188 points touching exactly that nerve.

pnpm vs npm vs yarn vs bun: The Real Comparison Nobody Gives You in 2025

I used all four in real projects. One wrecked a monorepo at 3am. Another saved my ass in production. Here's the unfiltered truth about every major package manager in 2025.
