m5l.eu is a Fediverse instance that uses the ActivityPub protocol. In other words, users at this host can communicate with people that use software like Mastodon, Pleroma, Friendica, etc. all around the world.
This server runs the snac software and there is no automatic sign-up process.
You can import and export Markdown files to/from Apple Notes in iOS 26 and macOS 26, nice!
It seems like just yesterday, Markdown was only used by developers.
📢 #Markdown support in tut
I have submitted a PR to tut (and one to go-mastodon) to finally support content_type on the /statuses payloads, which in turn unlocks text/markdown support if you’re on Pleroma, Akkoma, Friendica (all tested), and probably Misskey, Calckey and GoToSocial (not tested).
If you don’t know of it yet, tut is a full-featured terminal-based Fediverse client with vi-like keybindings, which also allows you to write posts in your favourite editor.
While it gets approved, you can use my fork if you already want to try out Markdown support:
git clone https://github.com/blacklight/tut
cd tut
go buildSee it working at https://marsh-sim.github.io/bibliography/
Because everything is written in regular files, the editor can autocomplete citation keys without any special tooling - they are just sections in another file. This kind of interoperability is why simple tools like text files and #ssg are so great.
I'm not a fan of hosting it on GitHub anymore, but there are already links in various places that I can't update, so this is the reasonable thing to do.

Just sharing the very bare-bones script I use to make static websites from markdown files. Currently use this for both the https://httpd.rocks and https://openbased.xyz sites:
