Thanks to everyone who came to our second edition of Caml in the Capital yesterday, we had a blast! Thanks to Jane Street for hosting us as well! #OCaml See you some time in September for the next edition

Did I continue my exploration of OCaml? Yes. Was it fun? Definitely. And did I learn a few things? Absolutely gilwath.com/articles/fro... #OCaml #Scala

- The purpose and design of Alexandrite - Differences between "normal" compilers and "analyzers" - Reasons to choose Rust or OCaml for compiler development - Internals of compilers, some optimizations and tradeoffs - Importance of clarity and posterity

One reason to love OCaml: all the package name tangentially related to camels

Video of @xvw.lol 's #BOBkonf2026 talk "A crash course on the OCaml module language" is now online! Find it here: bobkonf.de/2026/woestyn...

Bonsai_term looks very cool. blog.janestreet.com/strace-ui-bo... #ocaml

@scaleway.com are the risc-v nodes you provided permanently out of commission? Just planning what we do in OCaml CI land as they were very useful! www.tunbury.org/2026/06/03/e...

my life always seems to bring me back to building a social network of some kind and this karaoke site is the most glorious yet and I'm actually shipping things and able to respond to bug reports and feature requests fast enough to keep up

my wiki software is terrifyingly close to being finished,, it's now about 150 lines of ocaml plus a few hundred lines of liquid templates. i'm trying to keep complexity down as much as possible and i've found that doing layout stuff entirely in liquid templates is a good way to achieve that

I am a huge fan of Bonsai and Bonsai_term is an incredible extension. It's an amazing way to build rich TUIs in OCaml! blog.janestreet.com/strace-ui-bo...

superb piece of work getting merlin's typing recovery upstreamed into the OCaml compiler; it might even make 5.5! "the typer won't stop at the first error. Instead it will continue typing as much as possible, reporting other errors along the way" https://github.com/ocaml/ocaml/pull/14241

Caml In The Capital is happening again! Our #OCaml meetup is open to anyone: user, researcher, outsider who happens to be interested :) This time, we'll be hosted at the JaneStreet office in London. Please register here if you'd like to attend: www.eventbrite.com/e/caml-in-th...

.plan-26-21: some amazing undergraduate projects completed this week on TESSERA and OxCaml, speaking at Pint of Science, and a grab bag of hacking https://anil.recoil.org/notes/2026w21

decided to install and play around with OCaml and it seems pretty neat. pretty *different*, i assumed it would be more similar to F# than it really is, but i think I'm getting the hang of the differences. it's got a way faster cold start than F# and can also compile to tiny native executables :o

KaraokeCrowd is a really fun project because I can just post on Reddit and people tell me about more karaoke nights I didn't know about 🥹🧡 https://www.reddit.com/r/cincinnati/comments/1tloo2o/need_help_finding_all_karaoke_in_cincinnati/

The OCaml Users Survey is still open until May 25 (Monday)! If you haven't taken it, please take it now! 🐫 🧡 https://docs.google.com/forms/d/e/1FAIpQLSet4a4y7TL7zv6uS6iQk27NoJGYjhz4ANQVMRQuZNoVSfroBA/viewform?usp=send_form

I ported a Static Analyzer from Python to #OCaml . This Python code is part of the Spring 2020 edition of CSC255/455 Software Analysis and Improvement taught by Prof. Sreepathi at the University of Rochester. www.linkedin.com/feed/update/.... My #OCaml is improving but may not be up to the mark.

Today I wrote: Facade, a library for serialization in OCaml https://git.quiltro.org/lobo/facade

We have another confirmed talk for the #FPIndia #Bangalore #meetup tomorrow! Ishaan will talk about Discrete optimisation and #MiniZinc! hasgeek.com/fpindia/bang... #Haskell #PureScript #Erlang #Scala #OCaml #Rust #Clojure

Got nerd snipped into Installing OxCaml but already having issues with incompatibilities ...

I unexpectedly met another OCamleer at the LF Open source Summit. He delivered an awesome talk and there’s a call for maintainers for his DSL. 🐫♾️🐫 #OCaml #Linux github.com/multikernel/...

Do you know OCaml? I didn’t, not really, until I started digging in. I wrote up what I learned coming from Scala: gilwath.com/articles/fro... Part 2 coming soon, I will do some http and json so stay tuned. #ocaml #functionalprogramming #scala

"Roguetype is the first roguelike written in the OCaml type System." https://github.com/Octachron/roguetype/

Apparently agents do well with OCaml gertlabs.com/blog/llm-per...

been resurrecting my system packaging scripts to remember how it all works again https://anil.recoil.org/notes/oxcaml-packages

was looking at this earlier and tried to integrate tw to my yocaml site i was like hmmm not gonna work unless i strip away all my liquid templates and convert all the them to typed “html” using dream or smth else and the diff would be like 5000+ 200- 💀 im stuck with tailwind cli i guess

I should write a JS runtime in OCaml

The wait is over #Bangalore! #FPIndia #meetup this weekend! Saachi will talk about building chess provers using #Lean. Plus, the usual nerdy debates, and catching up with fellow FP heads. Don't miss it! hasgeek.com/fpindia/bang... #Haskell #PureScript #Erlang #Scala #OCaml #TypeScript #Rust #Clojure

Many years ago, a new engineer joined the company I was at and within a week called an all-hands to propose rewriting the entire product in Ocaml in order to eliminate bugs. I look at the bun story and wonder if these days they would have just pushed up a PR.

I really should write ocaml bindings to duckdb. Raven is such a cool looking numerical computing stack

guy who writes static site generators in ocaml: "templates are overrated, just write html from code" but the html from code is 600 lines of ocaml

i rewrote zig in rust, rust in typescript and typescript in ocaml. i then rewrote ocaml in zig

waffling over angstrom vs ocamllex+menhir

I feel like AI tremendously improves the situation for startups in Germany bc we now have more resources to implement all the legal requirements lol

historical aside: in OCaml, Lwt won out over Async because the guys at INRIA adamantly insisted any successor concurrency library run on their Windows workstations

Some further thoughts on voluntary AI disclosure for ocaml/opam packages discuss.ocaml.org/t/a-proposal...

Met someone new yesterday through a colleague. Mentioned I write OCaml for fun. Someone, told a friend and the friend asked if I was STRAIGHT. Apparently straight people can't get OCaml jobs

using ChatGPT image generation to incrementally improve on existing UI feels underrated easy to have deep conversations about purpose + goals side by side with getting UI ideas before even writing CSS or HTML

pleased to inform that my companion site generator for the `denote` package in GNU ELPA for Emacs, written in OCaml, supports the NetSurf web browser.

action shot from Fun OCaml 2025 in Poland great conference in a lovely place to visit

do I know anyone who runs a podcast or publication where this topic would fit: building a community-maintained database of karaoke nights in OCaml if yes, please make introductions or send me their links 🧡

Has someone in the ocaml community tried to create a modular monolith directory for a web app without struggling with cyclic dependency? Anytime I have tried to do that, I have faced cyclic dependency issues that I end up using a layered directory approach.

Today I learned that OCaml simultaneously supports optional function parameters and has automatically curried functions. But, like, imagine you supply a function call with all the non-optional arguments. How do you know if you’re trying to call the function with the default value, or curry it?

finally trying out Astring in OCaml and well, why didn;t I use this before, just replaced a regex with this and it was fun

is anyone into spreadsheets and karaoke? if yes. I have something interesting going on at KaraokeCrowd working on spreadsheet import tomorrow and need more karaoke gig spreadsheets 🥹😘

if we ship an ocaml stdlib enhancement we will include shit like `let (let&) = Fun.flip Option.iter` because allows you to do let& var = optional in stuff_that_only_executes_if_the_optional_is_some ```

I’m learning Ocaml, and it’s a functional language, but it also supports for loops and while loops directly in the language (like, “for” is a keyword) and I don’t think my little brain can handle it
