Ugh. I have a bunch of "projects" of mine on the internet, many of which run the most minimal (I'm talkin [0]) http servers on embedded hardware and stuff like arduino where HTTPS just isn't possible.
And the only I keep them online is because they don't require any upkeep whatsoever, and don't rely on external services for certs or whatever, and because the occasional web browser stumbles upon them and finds them useful. I really don't want to actually put work into them though.
