You have more knowledge on this than I did. I enjoyed reading about Freenet and Ceph. I have dealt with cloud stuff, but not as much on a technical-underpinnings level. My first freenet impression from reading some articles gives me 90s internet vibes based on the common use cases they listed.

I remember ceph because I ended up building it from the AUR once on my weak little personal laptop because it got dropped from some repository or whatever but was still flagged to stay installed. I could have saved myself an hours long build if I had read the release notes.
