The Bulgarian solitaire is a mathematical card game played by one person. A pack of \(n\) cards is divided into several decks (or "piles"). Each move...

The paramagnetic and glass transitions in sudoku
Article by Williams, Alex and Ackland, Graeme . J.
In collection: Basically physics
We study the statistical mechanics of a model glassy system based on a familiar and popular mathematical puzzle. Sudoku puzzles provide a very rare example of a class of frustrated systems with a unique groundstate without...

@PgSuper I think Ramanujan alluded to such experiences.
I wonder if some crazy mathematician ever thought of talking to a number as if it was a friend... (Because numbers are friends?)
oh, you like Mikhail Gromov? name five of his papers
@espectalll that might just be a coincidence: the ÷ symbol was used to represent subtraction in many places
Genuinely assumed this was about Prince William and really couldn't work out what the banks could possibly be doing.
@ColinTheMathmo as far as I know, none. I was hoping to get a dev instance set up at home today so I could play with adding an intermediate step so moderators have to approve signups, but got fed up with config nonsense
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 
...ok, maybe mosquitoes are worse
but other than that!!!! nothing!!!! **literally** nothing!!
Made some visuals like those from the latest Numberphile!

MathJax v3 has hit beta.
We're looking students to work on compiler / virtual machine things:

also a "Research Assistant/Software developer" for the same projects.
@andrewt I assume you've already ruled vim out of one of those bullet points (or "good")
Mrs L-P had a very happy accident at the photo printers
Found a roll of receipt paper while cleaning and could finally run a ~real~ ed(1) session // @_xhr_
@andrewt @ada @webinista as a colourblind person, HSL is basically the only way I can think about colours and get reasonable results. If I *know* that two colours have the same L value, it doesn't matter what my lyin' eyes say.
I do a similar thing on http://read.somethingorotherwhatever.com/
