You mean electricity bills for powering the storage? I guess buying 100pb worth of storage disks would be pretty expensive enough but since it’s an archive there is no need to keep it powered 24/7, just turn them on only when you need to. It’s just a hypothetical situation anyway, it’s a thing I wish to have access to; only an experienced sysadmin can actually maintain such great archive or its copy/backup
If you’d download the whole wikipedia be sure to download the whole commets section for each article to have a perspective on discussions on conflicting reasons for edits. Also include all the wiki media materials for all of the public domain literature, project gutenberg, entire archive.org, a good offline OS to be able to consume all of the information and you’re golden
Audacious. It’s in the post you made this comment to
Try Bodhi Linux - you can burn it to CD/USB or copy it on a Ventoy USB stick to test before installing and it is available for 32 bit systems
Bodhi linux is ubuntu/debian based (but no snaps out of the box) and is good for older hardware both because it is lightweight and because it has support for 32 bit architecture, but it comes bundled with chromium not firefox, but you can easily install ff (or even better librewolf) and remove chromium.
Also there are bsds - I don’t know about Bottles and Inkscape but you might be interrested to try out NomadBSD which is for USB boot but can also be installed on hardware, it is freebsd based and comes bundled with FireFox+UBlockOrigin (altho it’s an older version you’ll need to update the packages)
