If you're not comfortable using Nix flakes check out toolbox
How do you containerize stuff you install from source in a way that you can completely remove later?
It's not FOSS or free, but Reaper at least has a native Linux version, and it's a great DAW.
At least there's a matrix bridge for discord. You're still connecting to discord from your matrix client, but at least you don't have to install the discord client or access the website.
Here are some revised configs I put together as the docs were insufficient if it helps https://git.minnix.dev/minnix/lemmy_configs
I have been running my own PT instance for about 3 years now. I only post videos of things that interest me, plus a videocast of a The Linux Lugcast podcast we do. I don't post video after video like that. It's very sporadic. PT is not YouTube, you will not find that level of engagement. If you are looking for lots of eyes on your content, PT is not the route to take. If you are interested in federation and want to move away from centralized platforms, it is good for that.
You didn't mention if you were joining an existing instance or hosting your own. That will determine whether your current PC is adequate or not.
Honestly writefreely can be as elaborate as you want it to be if you self-host it. There are lots of options under the hood as well as the CSS being fully customizable. I host my own with a single core, 1GB of RAM and 16GB of storage and even that is overkill as pictures and videos are just embeds from other platforms. Plume is deprecated, and micro.blog is paid and not self-hostable. There is microblog.pub though which I haven't tried yet but looks promising.
I think this problem is relegated to being registered to larger instances. On one hand you get lots to choose from when it comes to your local feed, similar to how Mastodon works, on the other hand you have the problem you just mentioned. I know you bring up the problem of narrowing what you see, but if you're going to be on a big instance, there really is no other way than to subscribe to those communities you have a specific interest in. I'm on a smaller instance and I just take the time to go through communities that I may have an even fleeting interest in and subscribe to them, avoiding larger generic communities. This is the same strategy I employ when it comes to my news feed as well. I only subscribe to RSS feeds from sites I have an interest in.
Because otherwise random users can and will end up unknowingly participating in the hosting of child abuse materials, nazi propaganda, and so on.
You seem to misunderstand how PT works.
If you want to continue using Fedora try Kinoite or Silverblue. With their immutability and ease of rollback, I've really enjoyed using Fedora again.
If the instance supports those languages you can highlight them in your profile. If you don't see them, then they haven't been enable instance wide.
Very much the nice price
