"b-but benchmarks!!1!!" people are both right and at the same they sometimes sound like those who genuinely believe that "facts don't care about your feelings"

i think we need to accept that 80% of performance is vibes and feelings

Reposting with alt text since this is going around again!

Two panel comic in black and white. In the first panel, a bunny sits in the grass, surrounded by sparkles and flowers, on a white background. The second panel zooms in on the bunny's face and the background is black, with white text handwritten in all caps on it: "TOUCHING GRASS ISN'T ENOUGH, I NEED MONEY"

Signature: SLEEPIMALI (and the year the comic was made, 2023)

Day 2 of hacking before ICFP

Finally finished odoc markdown backend support in dune, it should make release nicer documentation sites (docusaurus, vitepress, etc) or even github itself

Before (odoc html) After (odoc to markdown |> vitepress)

You gently run your hand through the rack. You can feel it—pure cotton, rich wool, Irish linen. The plump buttonholes are handsewn; the buttons attached with a firm shank. You flip the price tag over. It's affordable

You buy the jacket and go home, which is only 15 mins away. Your apt is $600/month

not cut elimination sorry just cut

lexa! @lexa.qexat.com · 1d

i mean the deduction theorem would arise from cut elimination anyway, that's not what i'm looking for :p

what interests me is transportation from theory to metatheory with a category theory perspective

i'm trying to express the informal idea that A → B ∈ Th ⊢ 𝓕(A) ⊢ 𝓕(B) ∈ M which can be read as "if A implies B in the theory, A entails B in the metatheory" (modus ponens again)

lexa! @lexa.qexat.com · 1d

if Th satisfies (a → b) → Th a → Th b and M satisfies (M a → M b) → a → b then that is to say that Th admits modus ponens (a → b, a ⊢ b) as (M a → M b) → (Th a) → (Th b)

technically you could be satisfied with M (M a → M b) → M (Th a) → M (Th b) [Th wouldn't be free, bounded by M, harder to prove]

lexa! @lexa.qexat.com · 1d

M is a functor, Th is a sort of "cofunctor", not as in contravariant [(a → b) → Th b → Th a] but as in the opposite direction [(Th a → Th b) → a → b]

it was yesterday night the stream lasted for almost 5 hours don't tell me you missed it

lexa! @lexa.qexat.com · 1d

clearly you can tell i wrote this at almost 2 am because we're supposed to get (Th a → Th b) → M a → M b
