If you’d like to run them on the same Ubuntu VM, I’d recommend deploying them using docker, as that will make avoiding port conflicts much easier as well as keeping each application isolated.
You should also look into a reverse proxy so you can reroute traffic from your desired subdomain to non-standard ports (otherwise you’ll need to specify ports in the URL which gets weird). I recommend Nginx Proxy Manager which can also run in docker.
You could spin up another VM for Lemmy if resources get tight and you don’t mind the extra cost.
I’ve heard that this is instinctual. We have evolved to find crying and upset children intolerable because it motivates us to do something about it.
Children are also exceptional and figuring out how to push our buttons because they instinctively find and repeat behaviors that get a reaction out of their caregivers when they desire attention.
Unfortunately the most motivating emotions are often negative ones.
Dude that graphing calculator was awesome—way ahead of anything at the time.
