System One AI for Cybersecurity: Not Every Decision Needs a Generative Model

Security pipelines ask frontier LLMs millions of (basically) yes/no questions. I tested whether cheap decision models like Jev can triage HTTP responses instead: four models, three LLMs, one open harness. The answer is a qualified yes, plus a warning about what the gate throws away.

Chaos Threat Actors: Why Corporations, Parents and Legal Systems Fail against Teenage Hackers

A discussion on Joe Tidy's "Ctrl + Alt + Chaos" and my takeaways. From the release of Julius Kivimäki to the rise of "Chaos-Evil" groups, I analyze company reactions to hacks, parents navigating the digital minefields and why the legal system might need a "cartel-style" overhaul.
