Recently, I added #ProxSnap to #PegaProx which allows you to quickly find snapshots of your VMs and Containers. You can also filter them by date to quickly identify older or even outdated ones and clean them up at a central point!

PegaProx with ProxSnap integration for Proxmox VE Clusters

So, yet again, I am stuck on a call where , for whatever reason, admins decided to go on vacation, and, for whatever fuck reason, did not share their Admin DB credentials with anyone else (also, #sharedauth credentials...who the fuck does this anymore?), and a DB went bellyup, and there was no way to fix it shy of restarting it.

I just cant even right now.

Here I am working today, on stupid #devops shit, when , and I am shocked to have to say this, but a Senior Architect tells me and I literally quote "Wendy, I dont understand #DNS nearly as good as you do, so can you help me understand the cadence of what goes first or second", and all I can think is, this guy is a developer and he stupidly asks me this question? how in the fuck?

A small update on NetBSD Cells 🙂

I’ve spent some time recently polishing things up and have updated the project page. I also built a new evaluation DVD image so it’s easier to try the current state of the project.

It now includes a few of the things I’ve been working on lately, like the reconcile engine in cellmgr, some early volume and backup management, and cellui for interactive administration.

If you’re curious about where the project currently stands, I wrote a short status report here:

Feedback, thoughts, and questions are always very welcome.

"Can you show what Cells for NetBSD actually does?"

Sure.

Fresh NetBSD install, deploy a Luanti server from a manifest, backup, restore, inspect processes inside the cell, then nuke everything again.

My personal record is <4 minutes.
The video is slower because OBS + VM + music nearly killed my laptop.

Cells for NetBSD... Lightning Talk without the Talk ;-)

You just provisioned a fresh Linux server. Within minutes, the SSH brute-force bots will arrive.

There are too many ways to build a firewall in Linux. I wrote a practical guide to the four major tools: iptables, nftables, firewalld, and ufw, including their mental models and deployable configs.

Also includes a deep dive into the "Docker Trap" (why Docker silently bypasses your default-deny rules) and how to fix it.

(And yes, I still spend the intro and conclusion reminding everyone that FreeBSD's PF is the undisputed king of packet filtering. Let's argue in the replies.)

Pushing Cells for NetBSD even further... cellmgr becoming a scriptable reconcilation engine with full lifecycle management including backup/restore, with cellui as the go-to TUI for midnight commander enthusiasts. And why stop there, when you could have a PAM authenticated web UI with feature-parity as well?

Chemnitzer Linux-Tage 2026: 28.–29. März – zwei Tage Open-Source-Praxis, Austausch und Inspiration. 
Besonders spannend: Unser Kollege Oliver Kautz mit seinem Vortrag „Seit 8 Jahren Infrastructure-as-Code – ein Erfahrungsbericht“. Sa., 17:00, Raum V1. 

Wenn du wissen willst, wie IaC nach Jahren Betrieb wirklich aussieht (Terraform/OpenTofu + GitOps, inklusive Lessons Learned), ist das ein Pflichttermin.
