Sometines I have a really hard time telling 0 and 1 apart.

About to upgrade the server that runs mathstodon.xyz. Server will be up and down for a bit

phew, this conference judges papers on both originality and innovativeness

Chill maths observation:

I like 98 and 99 because their prime factorisations feel kind of like they've taken different, slightly symmetric routes to almost the same place

Genuinely assumed this was about Prince William and really couldn't work out what the banks could possibly be doing.

Another attempt at setting up a mastodon development environment, another dismal failure.
This time: `rails db:setup` fails with "must be owner of relation account_domain_blocks". mastodon is the owner of that table. 🤷‍♂️ Postgres gives such terrible error messages!

I've turned account registration on mathstodon.xyz back on. I'm going to spend some time today thinking about how to deter spammers.

#programming idea:
your examples should be part of your automated #testing !

there is nothing more irritating then eg. finding a cool rust crate and not being able to run the examples :blobsad:

...ok, maybe mosquitoes are worse

but other than that!!!! nothing!!!! **literally** nothing!!
