Attacks on trans women are attacks on women. I'm not sure why we don't see this. It will affect us on all levels of society. I will not have my womanhood policed, nor will I have others policed. Why do we not see this? Why do I even have to post that cis women are affected for cis women to care?

I really enjoyed this year’s miniKanren ICFP presentations. While Gallois’s reversible Lustre-to-C compiler stole the show, I savored the modest talks just as much.

Has anyone watched this video that explains how cooperation games (Prisoner’s Dilemma) incentivize different strategies based on the shape/connectivity of the graph?
What game(s) do players play on social media? What are the *real* +/- rewards/penalties? Can we abstract them?

If we were to model social media as a game -- algebraically, categorically or otherwise -- how can small groups of people play the game in a way that's contrary to the behavior the social media companies designed to incentivize?
How many different ways can one play it "wrong"? Is there a cogame?

One of the best things we can do with social media, at this time, is to make plans to spend time talking with a small group of people.

miniKanren and Relational Programming Workshop 2025 - miniKanren 2025 - ICFP/SPLASH 2025
The miniKanren and Relational Programming Workshop is a workshop for the miniKanren family of relational (pure constraint logic programming) languages: miniKanren, microKanren, core.logic, OCanren, Guanxi, etc. The workshop solicits papers and talks on the design, implementation, and application of miniKanren-like languages. A major goal of the workshop is to bring together researchers, implementors, and users from the miniKanren community, and to share expertise and techniques for relational programming. Another goal for the workshop is to push the state of the art of relational programmi ...

This is a good talk explaining why Lean is more than a good proof assistant and what language folk can learn from the macro system and tooling.

Don't blame "the algorithm". Blame the people who dishonestly call it an "algorithm" for serving you slop.
But above all, don't blame yourself for being bad at computer when it's computer that's bad at you.

The Choose-Your-Own-Adventure Calculus is a small formalism that captures an interaction pattern where you repeatedly choose from the available options.
Examples include type providers, structure editors, theorem provers & more!

Let G be a magma (i.e a set equipped with a multiplication and no further axioms). Can you prove that if ∀ x y z, x = x(y((zx)y)) then ∀ x y z, x = x(y(z(xz)))? You can use a theorem prover, a language model, a SAT or SMT solver or even pencil and paper. Terry Tao is collecting proofs of this! 1/2

looks like the people at the Clay Institute are working over the weekend 😢
Today I have received by email: one disproof of the Riemann hypothesis, one proof that P =/= NP, one proof of the Riemann hypothesis, and one proof that Peano arithmetic is inconsistent (which follows from the two Riemann hypothesis papers, but this was an independent discovery).
