@christianp That's what I love about listening to mathematicians. The conversation becomes quite dizzyingly elliptical, and yet communication is obviously taking place!

MetaFilter is giving server errors! What will I do with myself instead?

I had an *extremely mathematician* conversation with a Professor colleague yesterday.

Her: There's this puzzle where someone's getting on a train -
Me: And the answer is 1/2?
Her: Yes! It's obviously 1/2, but the hard part is to show why.
Me: Proof by induction.
Her: That's what I tried, too!
Everyone else at the table: 🤷‍♂️ 🤷

79. THE LOCKERS PUZZLE. A man had in his office three cupboards, each containing nine lockers,
as shown in the diagram. He told his clerk to place a different one-figure number on each locker of cupboard A, and to do the same in the case of B, and of C. As we are here allowed to call nought a digit,
and he was not prohibited from using nought as a number, he clearly had the option of omitting any one of ten digits from each cupboard.

It's just occurred to me that command-line installation instructions for software that runs on lots of OSes should be delivered as a Twine story: you can go down different paths depending on your particular setup.

(currently reading a set of 'instructions' that concatenates notes for a plethora of OSes and optional dependencies into one incomprehensible monologue)

I'm thinking about tournament 'brackets', a month too late for Americans I think?

If you can predict the winner of a match 99.5% of the time, you've got a 50% chance of correctly predicting the outcome of all 127 matches in Wimbledon's ladies' singles tournament.

\(p = 0.99456\) is the solution to

\[ p^{2^7-1} = \frac{1}{2} \]

They did basically nothing for me! It was like film colour vs TV colour - a bit higher contrast, but it felt even harder to distinguish similar colours. They were the Enchroma glasses, and I'm a protanope.

I'm going to take part in a study of those glasses to "fix" colourblindness shortly. The manufacturer's website says my eyes are too knackered for them to work, but I'm curious to see what they do.

I've finally got round to writing a code of conduct for, guided by the MathsJam gathering code of conduct.
It's on the instance's about page at
Looks reasonable?
