Researchers found that meditation led to changes in activity in the amygdala and hippocampus, key brain regions involved in emotional regulation and memory. The study may help explain the positive impact of meditation on memory and emotional regulation.
My TL;DR guide for self hosting on a Pi.
Get Pi
Install DietPi
Install Docker, Docker-Compose
browse the LinuxServer.io fleet
create docker-compose file with needed 'stuff' (letsencrypt, NextCloud, etc)
run.
A pi4 4gb should run NextCloud plus other "stuff" without an issue (Mine has a bunch of *arr's). As other's mentioned, storage might be an issue. My Pi's all point back to a NAS for file storage/serving.
