Understanding NVMe SSDs
NVMe is a protocol for non-volatile storage over PCI Express; form factor, lane count and protocol are not the same thing.
Last checked: 18 Oct 2026Power measurement boundaries and meter accuracy
Comparable power readings require the same measurement boundary, a suitable operating range and openly documented measurement uncertainty.
Last checked: 18 Oct 2026Documenting an exact hardware configuration
Vendor and model are insufficient for comparison data: SKUs, quantities, firmware, population and operating state together form the hardware fingerprint.
Last checked: 18 Oct 2026Calculating homelab energy costs
Power becomes kilowatt-hours only across time; cost is obtained by multiplying that energy by an explicitly selected unit price.
Last checked: 18 Oct 2026Virtualization and hypervisors
A hypervisor allocates physical resources between virtual machines that each run their own operating system.
Last checked: 18 Oct 20263-2-1 backup and restore testing
A backup becomes credible only when separate copies exist and restoration works under documented conditions.
Last checked: 18 Oct 2026Proxmox or ESXi for a homelab
Proxmox VE and ESXi both run a homelab; what decides are licensing, hardware compatibility, backup tooling and a tested migration path.
Last checked: 18 Oct 2026Hosting a Minecraft server at home
A Minecraft server for friends mainly needs a fast core, sensibly chosen memory, a reachable port, tested backups and a power bill you measure rather than guess.
Last checked: 18 Oct 2026Reverse proxy for a homelab
A reverse proxy accepts connections, terminates TLS and forwards by hostname to internal services; it is an entry point, not a replacement for identity and policy.
Last checked: 18 Oct 2026Homelab backups with restic or Borg
restic and Borg create encrypted, deduplicated backups; a 3-2-1 setup needs separate targets, retention rules, integrity checks and a real restore test.
