Okay, it’s been 6 days, never mind my reduced weekend computing. Here’s how it went.
In Emacs, I used:
Nothing involving the modern web worked. That’s not unexpected, but it’s easy to forget how deep the rabbit hole goes. I had been syncing my org-mode files with my phone using Nextcloud, because it’s pretty transparent given the clients on both desktop and Android. But the Nextcloud client was a no-go on this computer, because the desktop client makes you log in with OAUTH through your browser, and NetSurf does not cut it. There’s a command-line client, but its exclude lists are configured through the desktop client… In the end, I ended up moving my sync to git, and finding a decent git client for Android (MGit, on F-Droid) to use.
I didn’t get the clarity or calmness other people got; maybe I already have those, because I didn’t change my computing habits very much. I did get back in touch with the kind of desktop sysadmin stuff I had to do with this kind of machine back in the day, and it gave me some things to think about for permacomputing purposes.
