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

I think everything is now upgraded

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

Intriguing! A brick that's like the 3D analogue of A-series paper: you can cut it in half to produce two bricks similar to the original

never mind , I'm concentrating my efforts on the real future of mathematics:

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

oh, you like Mikhail Gromov? name five of his papers

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!

#programming idea:

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

...ok, maybe mosquitoes are worse

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

Made some visuals like those from the latest Numberphile!

A Mastodon instance for maths people. The kind of people who make $\pi z^2 \times a$ jokes.
Use $ and $ for inline LaTeX, and $ and $ for display mode.
