The Last Poppleberrys: A Surname on the Brink

Who Still Runs Windows Server in 2026?

Despite the narrative that Linux owns the server world, Windows Server still accounts for roughly 32% of x86 server OS shipments in 2026. In this episode, we explore where Windows Server actually earns its keep — from Active Directory identity lock-in and Exchange hybrid deployments to SQL Server dependencies and compliance frameworks that reference specific Group Policy GUIDs. We also examine the human factors, like IT teams built around Microsoft certifications, that keep Windows Server running on bare metal and in VMs across enterprises. This isn't about whether Windows Server is good or bad — it's about understanding the architectural, regulatory, and organizational realities that keep it in production.

Server Distro Showdown: BTRFS, ZFS & Pragmatic Picks

Why do server admins make such boringly pragmatic distro choices while desktop users debate wallpaper defaults? This episode unpacks the real decision tree behind server distro selection — where kernel versions, package availability, installer behavior, and support lifecycles matter far more than identity or aesthetics. We trace how filesystem support for BTRFS and ZFS can effectively pick your distro for you, examine what "supported" actually means across Ubuntu, Debian, OpenSUSE, and Fedora Server, and explore why Ubuntu dominates at 33% of web servers while Debian holds 20%. We also cover the death of CentOS, the rise of Rocky and AlmaLinux, OpenSUSE Leap's impending migration to ALP, and the CDDL vs GPLv2 legal standoff that keeps ZFS out of the Linux kernel tree.

What Virtualization Actually Costs on 2026 Hardware

When you reflexively install Proxmox on a new Ubuntu server, what performance are you actually trading for those snapshot and rollback capabilities? This episode digs into real benchmark data from a Ryzen 9 7950X running Proxmox 8.3 with a single Ubuntu VM — measuring CPU cycles, memory access, disk I/O, and network throughput. We trace the overhead from VM-exits on Intel and AMD hardware, nested page table walks, virtio driver paths, and the real-world cost of that hypervisor translation layer. The answer: 2-6% depending on workload, with specific numbers for PostgreSQL, Nginx, 7-Zip compression, and NVMe disk operations.

RAID Reshaping Showdown: BTRFS vs ZFS vs XFS

You started with three drives in RAID5. Now you've got a fourth drive and want RAID6. Can you reshape in-place without backup-and-restore? We put BTRFS, ZFS, and XFS through the wringer. BTRFS has the elegant architecture but marks parity RAID as "unstable." ZFS will look you in the eye and say no — immutable vdevs mean you're buying new drives to change parity levels. XFS plus LVM uses Linux's MD driver for production-grade reshaping since 2017, but comes with tuning gotchas. If you're a homelabber hitting the three-year wall, this episode tells you which filesystem lets you grow without regret.

Proxmox vs Stock Linux for Home Servers

When your home server dies and you're rebuilding, the default choice for many is Proxmox — but is it actually the right call? This episode digs into the real differences between running Proxmox VE and a stock Ubuntu Server install with KVM and libvirt for a simple three-VM setup. We cover resource overhead (Proxmox uses about 1GB RAM idle vs ~350MB for minimal Ubuntu), ZFS management differences, USB passthrough for Zigbee dongles, and the hidden cost of running Corosync on a single node. If you've ever wondered whether muscle memory is hiding architectural inertia in your homelab, this one's for you.
