Hi all! Mastodon newbie here. I'm trying to find my community of #scientists to follow-- mainly #deepsea #marinebiology, #entomology and #datascience but definitely not limited to just those. Any help is greatly appreciated!!

Dirty secret time.

Today I logged in via the web to the old birdscroller. I’m not proud of myself, but I do have to say.

My old list is basically a random wasteland of can’t deciders.

The best bit by far was seeing our good pals still down in the trenches pitching adverts for:

https://mast.hpc.social

I’m ok with all of that.

Can a 2,048 character toot really still be called a “toot”?

Or, may it then only be called a “sparkling trumpet”… 🤣

Stumbled across a #fediverse viewer.

Calls API requests to find peers and builds an SQLite database.

Driven by:

async with session.get("https://" + instance + "/api/v1/instance/peers") as r:

https://github.com/H4kor/fediverse-explorer/blob/main/pipeline/instances.py

Found myself!

https://h4kor.github.io/fediverse-explorer/

Gives you a sense of peering in the network as size and scale.

While I'm down in the Postgres weeds, this is a friendly public service reminder to put a bio and avatar on your accounts so folks will know who you are! 😃

Looks like >10% of accounts currently don't, but that's ok.

Just interesting seeing data.

(total accounts)

select count(*) from accounts;
-------
30871

(empty avatar)

select count(*) from accounts WHERE "avatar_file_name" IS NULL;
-------
3178

(empty biographies)

select count(*) from accounts WHERE "note" = '';
-------
4395

Well the ncdu and the file sizes in the database track and match up.

I think the difference in the "file" (inode) count is literally the /120/124/123 hashing that's adding "file" count.

Yeah - this should have been an object store - POSIX is gonna get mad!

Yep - confirmed!
