Am Danish. This is fairly accurate, a solid 60% of Danish is just random guttural sounds. This documentary however misses that the remainder is 30% raw deadpan sarcasm, and 10% English words pronounced in an awful accent.

To contrast and compare, this is an average modern Swedish television quiz show: https://youtu.be/lzv6ljgwgzs

I really don’t see much benefit to running two clusters.

I’m also running single clusters with multiple ingress controllers both at home and at work.

If you are concerned with blast radius, you should probably first look into setting up Network Policies to ensure that pods can’t talk to things they shouldn’t.

There is of course still the risk of something escaping the container, but the risk is rather low in comparison. There are options out there for hardening the container runtime further.

You might also look into adding things that can monitor the cluster for intrusions or prevent them. Stuff like running CrowdSec on your ingresses, and using Falco to watch for various malicious behaviour.

ZFS doesn’t really support mismatched disks. In OP’s case it would behave as if it was 4x 2TB disks, making 4 TB of raw storage unusable, with 1 disk of parity that would yield 6TB of usable storage. In the future the 2x 2TB disks could be swapped with 4 TB disks, and then ZFS would make use of all the storage, yielding 12 TB of usable storage.

BTRFS handles mismatched disks just fine, however it’s RAID5 and RAID6 modes are still partially broken. RAID1 works fine, but results in half the storage being used for parity, so this would again yield a total of 6TB usable with the current disks.

SSD longevity seems to be better than HDDs overall. The limiting factor is how many write cycles the SSD can handle, but in most cases the write endurance is so high that it’s unreachable by most home/NAS systems.

SSDs are however really bad for cold storage, as they will lose the charge stored in their cells if left unpowered too long. When the SSD is powered it will automatically refresh the cells in the background to ensure they don’t lose their charge.

Factorio. I saw transport belts in my dreams.

My home-assistant installation alone is too much for my Raspberry Pi 3. It depends entirely on how much data it’s processing and needing to keep in memory.

Octoprint needs to respond in a timely manner, so you will want to have the system mostly idle (at least below 60 percent CPU at all times), preferably octoprint should be the only thing running on the system unless it’s rather powerful.

If I were you, I would install octoprint exclusively on your Raspberry Pi 3, and then buy a Raspberry Pi 4 for the other services.

I’m running Pi-hole and a wireguard VPN on an old Raspberry Pi 2, which is perfectly fine if you are not expecting gigabit speeds on the VPN.

I personally trust Asus, EVGA (Rip), Gigabyte, Palit, PNY, Sapphire and XFX when buying graphics cards.

My current card is a Geforce GTX 1060 6GB from Asus that I bought in 2017, and it hasn’t skipped a beat.3A

While shorter lived certs certainly improve the general security, certificate revocation lists are what you need if a cert gets compromised.

Wait until you set up cert-manager to issue both Let’s Encrypt certificates, as well as generating your own CA and issuing certs from your own CA where you can set the validity however want.

The reason a VPN is better to expose than SSH, is the feedback.

If someone tries connecting to your SSH with the wrong key or password, they get a nice and clear permission denied. They now know that you have SSH, and which version. Which might allow them to find a vulnerability.

If someone connects to your wireguard with the wrong key, they get zero response. Exactly as if the port had not been open in the first place. They have no additional information, and they don’t even know that the port was even open.

Try running your public IP through shodan.io, and see what ports and services are discovered.

As others have already said, set up a VPN like wireguard, connect to the VPN and then SSH to the server. No need to open ports for SSH.

I do have port 22 open on my network, but it’s forwarded to an SSH tarpit: https://github.com/skeeto/endlessh

Yes indeed, and the ability to parse JSON messages and further filter the results is quite powerful.

I use Promtail+Loki+Grafana on my home server, which is decently performant, light on resources and storage, and searchable. It takes a little effort to learn the LogQL query language, but it’s very expressive.

I’m running it on Kubernetes, but it should be pretty straightforward to configure for running on plain Docker.
