Multi channel radios!
(factoriobin.com)
So I had a problem. I wanted to be able to broadcast a set of circuit signals representing a list of required items for a given outpost. The problem was that the radio only supports green and red channels leading to N>3 outputs intermixing signals.
Solution: Use a repeating clock that sends a signal only if Z={{my_chosen_channel_num}}. There's some odd stuff going on combinator wise to keep signal values in memory while the Z timer is on a different channel. Also requires a single clock radio blueprint in order to keep receivers and transmitters in-sync with one another.
This is my first time fiddling with circuits more advanced than if X > Y inserter_enabled so if you find a way to make this better LMK
Proxmox with all of its warts appears to be the better hypervisor. If your host has the headroom like others suggested: proxmox with a VM hosting docker/podman.
I have to say running proxmox saved me from running to the basement or opening up IPMI a few times already when making suspect changes to a VM that otherwise would have taken down the network of my host.
ATM I’m running Proxmox with Nixos VMs running mixed docker/podman containers. It works out pretty well for my use case and with some opentofu fiddling I have most of my infrastructure defined in config files if that’s a rabbit hole you want to go down.
As for my experience with docker vs podman I have to say podman can pretty much do whatever docker does with the exception of docker swarm. You may have to do some digging to handle more advanced networking/gpu setups.
The only thing I have running docker atm is a gluetun container because container to container networking took more than 15m of research with podman so I fell back to the very well documented path using docker.
