I figured I could simply upload them on our webserver, so here you go:

• Sound of the cleaned keyboard: https://quantentoast.de/ibm-model-m-cleaned.mp4
• Sound with tapemod applied (no very noticeable on the video): https://quantentoast.de/ibm-model-m-tapemod.mp4

Thank you

I can’t imagine the sound of a room with like 20 pupils, each hammering on such a keyboard.

I’ll do that! Question is where to post it. Lemmy doesn’t support videos.

That’s an interesting question. At the time being, I think the only way is to do regular backups and store them at a friends for example. That way an instance can be restored after the server has been taken.

Really the only way is to not save anything, or perhaps some sort of blockchain for all the comments and posts?

Blockchain is an interesting thought - or maybe something similar to Matrix. All instances have their own copy of a post and sync with each other. That way it doesn’t matter if one instance disappears. Though, that would probably not comply with the Fediverse idea? Interesting thought experiment non the less!

As far as I know they seize everything if there’s a warrant. No matter whether it’s relevant for said warrant.

Edit: Sorry, misunderstood your comment; Don’t know what the reason for the warrant was.
