The design of Pinboard exists in a similar but self hosted service called linkding [1]. I've been self hosting with Docker for a few years with no issues I can recall. Just checked and it does have the responsive forms as well.
Thank you! Linkding has everything I wanted from Pinboard (a bit nicer interface :)). I just set it up, imported everything from Pinboard, and will probably be happy.
Pinboard: Settings -> Backup -> "HTML (legacy Netscape format almost everyone can read)"
Linkding: Settings -> General -> Import "Import bookmarks and tags in the Netscape HTML format. This will execute a sync where new bookmarks are added and existing ones are updated."
The stuff in quotes is verbatim from the admin panels, I have not tried it.
Yes, if you count the export from Pinboard to Bookmark.html and then import to Linkding for once.
One weird thing though is, that Linkding does not have marking a bookmark "read" on first click: This is the most useful feature on Pinboard for me.
Via the pinboard-bookmarklet I pile all the links I come across, then mass read them and can track what's been read because the first click marks them on Pinboard.
The old SmartThings zigbee outlets are rock solid as well, and also have current monitoring. I used mine both as a repeater and to detect a jammed auger in my cat feeder.
Second for this -- I worked on a product that used their back-end API several years ago (just before they were acquired). Great group of developers over there.
Rufus (the ISO to Flash Drive app) recently added a feature to create a local user right into the installation media, remove telemetry, and remove windows 11 hardware restrictions. It's worked like a charm so far.
