Hello, i'm the author of this document although it's just a draft for the moment (lots of TODOs in there) which is why it's not on my blog yet.
nullpointer is just a file upload system of which ttm.sh is an instance residing in the tildeverse. I sometimes use it to publish drafts to collect thoughts/feedbacks on ideas i have. I'm also part of the tildeverse. I reside on thunix.net and do sysadmin for fr.tild3.org. I'm often around on #thunix, #selfhosting (etc) on tilde.chat in case you're also around :)
> I am a lifelong sysadmin, and have thought about #2 frequently. I am thinking seriously about making it a research project.
I think a lot of us have been obsessed with this idea for a while, but nobody to my knowledge has done it yet. If you feel like exploring this idea, amazing! It is in my view a complex-yet-solvable problem that many projects have failed to deal with because they've been too focused on narrow use-cases and not on the broader conception of a standardized specification ecosystem for selfhosting. If you feel like exploring this idea collectively (for example by cooperating on a standard for which you would contribute a specific implementation), count me in. I think a lot of brilliant people will be glad to board the ship once it's sailing!
If you'd like to see where this idea has taken me so far, take a look at the joinjabber.org project. The entire infrastructure is described in a single, (hopefully) human-meaningful configuration file, with Ansible roles implementing it: https://codeberg.org/joinjabber/infra
Wish you the best, please keep me updated if you have more thoughts on this topic or would like to actively start a such project
