Lessons from running DevRel in 2026: why data gets you buy-in, why LLMs are a third distribution surface, and what I actually do in the first 90 days.

How I distribute GPU workloads across two Proxmox nodes using LXC device binding - VRAM strategy, LXC passthrough config, and Tdarr distributed encoding.

How I built a GPU-accelerated local voice pipeline for Home Assistant using faster-whisper, Piper TTS, and Ollama - zero cloud required, and the failures that got me here.

Our traffic was declining.

I built a few Claude Code skills for myself because I was tired of copy-pasting the same prompts.

A week-by-week plan from first inventory sync to automated governance.

AI for cloud operations is only as good as the data behind it.

Map SOC 2 and CIS controls to SQL queries that run daily.

Write cloud security checks in SQL instead of proprietary policy languages.

Deploy-time policy checks miss console changes, configuration drift, and external changes.

Most governance models fail because they enforce rules about infrastructure they cannot see.

Engineering toil from fragmented cloud visibility costs $47K-$90K per engineer yearly.

Most teams spend weeks preparing for audits that should take hours.

Security teams spend more time correlating information than fixing problems.

Cloud CMDB best practices for multi-account environments - automated discovery, tiered sync strategies, SQL-based querying, and historical data retention for compliance.

Traditional CMDBs miss most ephemeral resources because containers live just minutes.
