I once heard that there is a theory that things written on yellow is more memorable. Which is why the default original color for legal pads, post-its, and highlighters is yellow.
So yellow should be what ever you need to memorize more. So it depends on your teacher and how much of the subject matter needs to be memorized. I’d say it should be history as there are a lot of dates and minute details, but I could also understand it being used for any subject that needs memorization like foreign languages, science, and even math.
Blue and green are both calming colors so those should either be reserved for that classes that give you the most stress or the classes that benefit the most from being calm, like creative writing or music.
Red is an exciting color, use it on what ever subject you are most confident i or interested in.
I guess I think the bearded guy (wait…it that a beard or just a long mustache?) Is using my system correctly.
If you like xfce, I think that kde is more similar to it than gnome. So I would recommend giving kde a try too.
An easy way to test out both is to just use a live image booted from a USB. You could always install them to your everyday PC but then you have a lot more packages installed and I personally would rather keep my installed packages to a minimum. If you can’t do a live cd because your os doesn’t provide one then I would try a vm or a different drive that you can boot into.
I would say that if you are going to host it at home then kubenetes is more complex. Bare metal kubernetes control plane management has some pitfalls. But if you were to use a cloud provider like linode or digital ocean and use their kubernetes service, then only real extra complexity is learning how to manage Kubernetes which is minimal.
There is a decent hardware investment needed to run kubernetes if you want it to be fully HA (which I would argue means it needs to be a minimum of 2 clusters of 3 nodes each on different continents) but you could run a single node cluster with autoscaling at a cloud provider if you don’t need HA. I will say it’s nice not to have to worry about a service failing periodically as it will just transfer to another node in a few seconds automatically.
