I’ve never heard of anything working that way. The preferred algorithm is RFC 8305 “Happy Eyeballs,” which uses whichever network responds first. Even if your clients prefer IPv4, having IPv6 available allows you to access some resources that are not available over IPv4.

Matter uses IPv6 but it does not require you to have IPv6 internet. As long as the router isn’t blocking IPv6 router advertisements and IPv6 traffic between devices in your LAN you should be okay.

Would the MacBook Pro or rpi4 with a second Ethernet nic running a firewall before the routers also fix the issue of not getting security updates?

No. For most routers, this provides no additional protection to the router. Your router should not be accepting connections from the WAN side that would be blocked by the firewall, but consumer routers almost always initiate connections to the WAN side, indistinguishable from normal client traffic to your firewall, and accept connections from the LAN side, invisible to your firewall. If the firewall blocks all incoming requests, it would create problems for UPNP, effectively giving you CGNAT, even if the firewall does not perform address translation.

At least for some laptops, you cannot just remove the battery. If the battery is removed, the performance may be throttled. This is true of very old MacBooks.

In the US, most IPSs have remote access to your modem as well, even if you purchased it yourself from a store unaffiliated with your ISP.

Enabling SSH password authentication is unnecessary and not a good idea, especially if your temporary passwords are simple. I haven’t used Hetzner but there is probably a way to upload a file or to paste into the console, or else if you fix your keyboard you could at least type a URL to download the public key from the internet. You may want to look into cloud-init instead of manually installing and configuring your VMs.

LUKS may not make your server meaningfully more secure. Anyone who can snapshot your server while it’s running or modify your unencrypted kernel or initrd files before you next unlock the server will be able to access your files.

curl bash is not as bad as people think. Nobody downloads and reverse engineers binary packages off of these websites before running them with the same permissions.

If you’re running insecure services, you can restrict them to be accessible by vpn. I have a mix of internet accessible and vpn accessible services using the tailscale nginx plugin.

If you want to send all your traffic over a vpn, you will either need to route all your traffic through your own vpn or use some sort of multiplexed vpn. tailscale can do this with mullvad, but it’s not yet possible with headscale.

Kubernetes is much more complicated and powerful than Docker, and Docker Compose is more similar to the way you work directly with Kubernetes than it is to Helm, which adds in a templating system. Basically, from a Docker perspective, Helm allows you to configure your compose file, but not just by substituting variables. Helm can make structural changes such as completely adding or removing sections based on the variables used when loading the chart. The output of Helm is YAML, sort of like a compose file.

Kubernetes has a much more complicated system for describing workloads and their resources than Docker Compose, and it is extensible. For example, if you are running on AWS you can have Kubernetes attach EBS volumes to your pods, or if you’re on bare metal you might use LVM, and it’s not limited to things that Kubernetes natively understands like storage volumes: Cert Manager is a common piece of software that is deployed into Kubernetes that takes care of issuing and renewing TLS certificates for other software in Kubernetes.

I used to run Kubernetes at home with ArgoCD, but I’ve moved on to NixOS instead. NixOS is less powerful because it doesn’t have dynamic workload scheduling, but I don’t actually need dynamic workload scheduling or all the configuration necessary to facilitate dynamic workload scheduling in my house, and Nix is much nicer to work with than Helm’s gotmpl templating. Unless you like this kind of stuff or want to get into Kubernetes, you probably want to avoid it for running a few things on one host.

Helm is what is used for real world software deployments. It has its problems but it’s better than Docker Compose.

Just be careful with SD cards if you’re using SBCs. Home Assistant does a lot of writing and if your SD card can’t handle repeated writes you may suddenly lose everything. Keep backups to another device and have a replacement SD card ready if extended downtime is going to be a problem for you.

What is RentAHuman’s cut? This is a very expensive service to operate. If an LLM posts a request for somebody to go pick up a package, what happens if the package never existed? What happens if the human just says that it never existed and takes the money or even the money and the package? Somebody in the middle needs to be arbitrating between AI agents that are notorious for making things up or getting details wrong and humans that just want to make quick money. Nobody is going to send requests if the humans are randomly stealing and nobody is going to fulfill requests if sometimes the request is unsatisfiable and you don’t get paid.

I have 1 podman container on NixOS because some obscure software has a packaging problem with ffmpeg and the NixOS maintainers removed it. docker: command not found

Quarto and Docusaurus are for documentation. You may be looking for a more general static site generator like 11ty.

Claude says he’s sincerely sorry that users feel software quality isn’t a priority, probably.

I don’t know what the plugin does but script to append an audio file to all audio files is possible to do cleanly in just three lines. Being able to write three lines doesn’t make something good at programming, and taking many more lines would make it bad at programming.

Many senior level “software engineers” are just tenured programmers and they’re managed by business people who don’t know software engineering either. One of the major benefits of using off the shelf software libraries is that they generally work as expected and have been through much more testing than something you just wrote, and often these libraries even receive free or cheap maintenance updates. You don’t want your developers wasting time reimplementing things and then wasting more time maintaining those reimplementations.

Getting the AI to write it is like mitigating the initial reimplementation cost by going to Fiver.

Wireguard normally runs with higher than root privileges as part of the kernel, outside of any container namespaces. If you’re running some sort of Wireguard administration service you might be able to restrict its capabilities, but that isn’t Wireguard. Most of my devices are running Wireguard managed by tailscaled running as root, and some are running additional, fixed Wireguard tunnels without a persistent management service.
