It’s not always takedowns either, just the developer deciding to nuke their own repos. Real annoying, although it’s making me more vigilant about forking/mirroring important repos.

It’s mainly Linux Unplugged where that stuff leaks into it. I haven’t heard it on “self hosted” very much.

Calibre is used as a server all the time, see calibre-web.

calibre-web is technically not Calibre and is written and maintained by different people, although it does use the Calibre database (and I believe it must be created with desktop Calibre initially). But it’s a good option and I highly recommend it.

you just load your books from Calibre (or right through USB if you’re hardcore for some reason) and you’re basically off to the races.

There’s also an OPDS server option with calibre-web that you can use to load books from if you’re using koreader.

You can also use the Kobo server replacement option with calibre-web although I personally couldn’t get it to work at the time I tried it. But this will give you a sync option that works like the official Kobo server which is quite nice.

AMDGPU virtio native context is somewhat of an equivalent to the other options, although the pieces are not all available yet. Linux guest only as well.

And there’s Venus but that’s for Vulkan only (but a lot can be done with that alone on Linux guests).

There is a case to be made that people should be a bit more well rounded in general, and not just find a specific niche.

So non-technical people should still have a decent familiarity with computers and maybe be able to do some very basic coding. And technical people should spend some time working on their written and verbal communication.

Because in both cases, it makes people more effective in their roles.
