Looking forward to next days for the OCaml and ML workshop @icfp_conference

every great product has a gambling system, which is why I feel the endorphins from CI yoloing

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)

Day 1 of hacking before ICFP! 🐫 Releasing opam packages used to take me ~1 hour each time. So I automated it. Now? On each new git tag → dune-release-action does everything (GitHub release + opam-repository PR). Please use it and report issues github.com/davesnx/dun...

just landed in Singapore after 16h on a plane 🫩 second time here, this week is @icfp_conference. If you see me, come say hi. also, any coffee recommendations?

react compiler is the same as flambda in ocaml wowzers

github needs a spam PR filter right now. This is beyond ridiculous (and happens every month)

when Ruby devs are interested in OCaml, it's over, we are mainstream af

Singularity, please don't take over yet, I'm finishing CSS extraction. The css output is still not atomic, which is essential for composition and it matters a lot for big sites!

reason-react mentioned lets gooo oh wait, no

CSS extraction is the last feature I want to implement into styled-ppx. Aside from CSS support enhancements and small refactors. I would consider it done, or at least 1.0.0

` tech debt ´ is the best-described concept in software engineering You’re literally creating debt with every keystroke. Sometimes it accelerates delivery, sometimes it mortgages your future.

writing CSS syntax is the best feature of styled-ppx, by far.

I'm a big fan of React. Nearly a decade of frontend dominance. Amazing patterns, backward compatibility, and measured development pace. Nobody gets fired for picking React; it feels mature, yet it still feels experimental. I love that.

ouch

One week until ICFP ✨ (in Singapore this year, btw) Super excited. My 4th time attending (and a bunch of the ahrefs crew will be there too) Should I organize a chill-run through the city?

I'm discussing with LLMs about styled-ppx's type-checker and the mf it's telling me that I need to implement type synthesis from bidirectional type-checking ``` Γ ⊢ e₁ ⇒ τ₁ → τ₂ Γ ⊢ e₂ ⇐ τ₁ ───────────── Γ ⊢ e₁ e₂ ⇒ τ₂ ``` tbh, it doesn't sound alien to me. Let me get my thoughts out

We have done an update on the Ahrefs industrial success story here: ocaml.org/success-stor... 🧡🐫 now there's a little more context

Nobody even works here. It's just me and 29 advanced AIs.

fun-ocaml tshirt goes harder this year 🔥🐪🌴

Implemented atomic CSS when extracting in styled-ppx bundle-size for atomic CSS vs not atomic CSS for a 200 pages site is insane Each page increases the bundle for all page's styles (all classnames must be pushed). In atomic, the increase is just "the new properties" (if any) x.com/davesnx/sta...

do you think it's based?

i like FP but i really wouldn't mind if the number of confidently wrong idiots that have no idea what they're talking about and just like it because it makes them sound smart would go down a bit

me: "i'm too busy creating, can't release stuff now" me later: "shit, that's the wrong mentality"

3 years since I finalised the demo of it for the OCaml Workshop in Ljubljana, Relocatable OCaml is finally submitted for review! 🥳🍾🎊

This is ready @FunOCaml

tomorrow will be fun

with all the work with CSS extraction, I improved the error messaging system. Multiple errors can be reported at once (the type-checker runs on each declaration!) and locations are mapped to the right value

I'm implementing the supreme feature for styled-ppx (I have been postponing for years!) Static CSS extraction at build time. No emotion runtime, minimal (or zero runtime) and everything dynamic via CSS variables.

if you use ocaml you don't get crypto scams like npm because nothing gets downloaded 10M times per week

If you ever thought "ruby people run the world", it's because they do

If your PR is full of silly AI comments, every commit has the claude-code avatar, half the “promised” features aren't there, you ignore previous tradeoffs from the project and it IT DOESN'T EVEN MAKE SENSE I’m not reviewing your PR

FYI I am going to give away this keyboard on Fun OCaml conference 2025. For free. The only unique design in the world. Bluetooth. QMK/VIA support. Hand lubed switches by me. Sound is amazing.

You rewrote your app from Flux → Redux → React Context then added react-query then migrated to TypeScript for “type safety” or whatever now debating if Effect is worth it please… don’t call yourself a Frontend Architect

If your company allows some days to work on open-source/learning/side-hacking. Don't waste those days, they are priceless, use them aggressively. The opportunity to grow your brain/skills is invaluable, literally, you become op

claude code breaks the github UI

POV: you’re about to review the sloppiest code you’ve ever seen

them: "I'm a functional programmer, I love abbreviations, code clean makes me happy" me: Sure, let's play a game

I love how different frameworks explore further patterns of RSC. In this case, the limitation of server-components imported on the client.

I haven't heard a good argument for doing this, and I hard countless of times confused users from abbreviations

If Redux solved asynchronous from day one, we would still all be writing Redux all day and never got tired of having 20 mapStateToProps

FUN OCaml is in exactly three weeks now! We are looking forward so much to the talks and workshops, and to getting together in person to hang out, share, and hack on things! 🐫 🥹 💖

Should I migrate my 10 flux stores into Redux?

First time reading a paper about React

TIL there's "whatever" and "any" in CSS, which styled-ppx's CSS parser doesn't support used in content: attr(<attr-name> <attr-type>? , <declaration-value>?)

We are entering the era of software becoming non-deterministic

those replies are hard to diggest. Elm is practically death, but some users and lovers still work in tools, real applications, big companies and even maintain forks

no cheating, post the last pic of your pet

When was the last time you changed your mind about something important about programming, and what caused the shift?

I'm a bit scared of React compiler becoming it's own language
