In this post, I’ll update you about the state of my dn42 network in 2026. Many things happened, I’ve lost a few POPs and will create a new one, but mainly, I had the opportunity to present my work on dn42 automation at FOSDEM'26!

This post describes the internals of my current dn42 network, with the extension from 2 to 7 POPs, and last but not least, the creation of a SSH-based auto-peering service.

I’ve just received my new Dell Pro Max 14 MC14250, and this is my installation notes for a modern Arch Linux installation, to support Secure Boot, Unified Kernel Images, systemd-boot, btrfs with snapper for snapshotting, and finalize the installation using aconfmgr, a simple configuration management system. The instructions are not detailed, the explanations are in the external resources listed at the end.

This post describes the usage of headscale and tailscale to create a virtual network based on WireGuard.

This post describes the usage of fio, bench-fio and fio-plot, to conduct a benchmark campaign and produce nice graphs. The tested system is a Dell R760 with 2 PERC 12 cards and 12 NVMe drives. The objective was to evaluate the impact of using hardware RAID on NVMe drives.
