I got rid of almost all the customized software in my life, and the few projects I decided to keep, I aggressively modernized, getting rid of thousands of lines of original code and adding many times more tests than I'd ever had before.
It very significantly improved my life and career to not have a second part time job maintaining a note taking app.
Some of the substitutions wound up being a step down in features, or required rethinking parts of workflows, but the time savings is such a benefit.
Custom notetaking tool with p2p sync-> Google keep
Custom batteries included Linux distro for SD protection, Kiosk browsers, offline docs, creative commons content packs -> a few scripts built into my control server on vanilla RasPi OS
Rsync-> Borg -> Kopia(to avoid fussing with Borg's community NAS package)
And actually, still browse the web and watch YouTube, but just on my non-work days.
Do you still host things? If so, do you host from home and how?
None of them were open to the public, I SSH-tunnel into them. All stuff just for myself.
I backed everything up locally and shut them down. They should be auto-removed at the next billing cycle.
