Drop Docker's daemon entirely. Podman rootless containers with podman-compose, drop-in compatibility, daemonless orchestration, and where it bites you.

LXC and Docker both containerize workloads, but one runs mini-VMs with init processes while the other handles single-process apps. Here's when each wins.

Coding agents get unrestricted shell access by default because it's easy, not because they need it. Here's the short list of what actually breaks without one.

Claude Code and other AI coding agents need somewhere to run. Compare laptop, Docker, throwaway VMs, and Cloudflare Workers on blast radius, cost, and setup.

A Go binary on FROM scratch gives you a 10 MB image with no shell, no libc, no /tmp. Everything that breaks on an empty filesystem, and how to fix each one.

Build Docker images that run on amd64 and arm64 from one command. QEMU emulation, native multi-node builders, CI caching, and manifest lists explained.

cgroups v2 unified hierarchy explained: read /sys/fs/cgroup/, limit CPU/IO/memory, use systemd slices and PSI pressure files.

runc, crun, and youki all run your containers, but they differ wildly in startup speed, language, and cgroups v2 support. Here's which to pick.
