How I migrated 62 Proxmox containers to OpenTofu with a self-hosted MinIO state backend - the audit, the wave migration, the stack, and whether immutable infrastructure is actually worth it.

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. Impressions down, clicks down. I'm a Developer Advocate who somehow also owns our web presence - and diagnosing it revealed two completely different problems that needed two different fixes. Real numbers, the weekly audit workfl

I built a few Claude Code skills for myself because I was tired of copy-pasting the same prompts. Then my coworkers started asking questions. Here is what happened when a personal productivity tool became team infrastructure.

The policies and controls that keep cloud infrastructure secure, compliant, and cost-efficient. Learn the 6 pillars of cloud governance and how to implement them.

Attack surface management finds exposed cloud assets before attackers do. Learn how ASM differs from CSPM and vulnerability management, with SQL examples.

CWPP protects cloud workloads at runtime. CNAPP unifies CWPP, CSPM, and CIEM into one platform. Learn when each makes sense and how they compare.

AWS IAM Identity Center replaced AWS SSO in 2022. Learn how to set it up, configure permission sets, use the AWS CLI, and audit access with CloudQuery.
