What this could become
A premium notebook for people who keep systems working.
coleman.ninja is shaped as a focused operator-brand concept: a useful parked landing page now, and a credible home for future practical infrastructure notes. The tone is field manual, not mascot; precise, useful, and calm under pressure.
Operator note pillars
Topics built around real-world reliability.
Automation and runbooks
Repeatable scripts, escalation notes, recovery checklists, and operational handoffs that reduce friction when the clock matters.
Homelab infrastructure
Network segmentation, self-hosted services, backups, monitoring, and the tradeoffs behind resilient lab environments.
Security hygiene
Practical controls: MFA, least privilege, logs, patch posture, secret handling, and the basics that prevent avoidable incidents.
Field-tested systems
Small decisions in DNS, certificates, storage, routing, and documentation that compound into stable platforms.
Operator judgment
How to decide what to automate, what to leave manual, when to simplify, and when to build guardrails instead of dashboards.
Start-here guides
Future-ready resource surfaces.
These guide tiles define the kind of content coleman.ninja can host without pretending the archive already exists.
Azure tenant baseline checklist
Identity, access, logging, break-glass, and backup questions every operator should answer.
Homelab recovery notes
Documenting what matters before a disk, firewall, or hypervisor forces the issue.
Security automation without noise
Lightweight automations that reduce toil without creating alert fatigue.
