Talks
Decks and deep dives on the engineering behind rfxn. Each talk ships with an overview, the key takeaways, and the original slide deck. The deck is the payload; the overview is the share-link.
Project Blacklight: An Agentic Defense Layer for the Open-Source Linux Stack
The pitch from the Anthropic Built with Opus 4.7 x Cerebral Valley Hackathon. Six days, 296 commits, one scorched-earth pivot, and an agentic defense layer that uses what most operators already have: ModSecurity, Apache, iptables, and a shell script. Built on Opus 4.7 + Anthropic Managed Agents.
Prompts to Pipelines v1.5: Stop Vibing, Start Engineering
The iterated version of the Claude Code harness talk. Five plagues of agentic development, four primitives (memory, hooks, subagents, settings) that fix them, and the fixtures to wire a CLAUDE.md, settings.json, and adversarial reviewer in an afternoon. The through-line: the model is capable, the instructions are the product.
Linux Malware Detect 2.x: From Zero to Protected in 28 Seconds
A deep dive on the maldet 2.x rewrite: 348K+ deployments, a bash-native scan engine that beats ClamAV on memory by 22x, and the architecture decisions behind a pure-shell malware scanner that ships on everything from CentOS 6 to Ubuntu 24.04.
