Docker, Podman, Kubernetes, and the rest of the container stack — runtimes, orchestration, and what’s worth running in a container versus on bare metal.

Every process thinks it owns all of RAM. It doesn’t. Your process has never touched real memory at all and why the CPU lies to your code on every single memory access.
A complete self-hosted AI agent on your own box. Reachable from Telegram by text or voice, runs your servers, connects to your tools via MCP, updates itself nightly.
What’s actually running in my home lab and how I built it all for under $70. From K3s clusters on VMs to self-hosted services with proper HTTPS - a complete walkthrough of my personal infrastructure.
Bare metal gives you total control over the hypervisor for maximum flexibility and resource optimization. Dedicated hosts keep things simple with the cloud provider managing the VMs for you.
