Sabine Schmaltz reports on her experience at FOSDEM 2025, including the process of setting up a functional programming BOF room! tarides.com/blog/2025-03-2…

3 weeks ago I had the opportunity to give a talk on OpenTelemetry. Here's the blog post following my talk. jahier.dev/opentelemetry-…

Very happy to announce a new release of #OCaml Eglot (1.2.0), an #Emacs minor-mode for OCaml using LSP via Eglot! A lot of bugfixes (since Emacs 30.x), and UX improvements! We also properly handle errors, client commands and capabilities! github.com/tarides/ocaml-… Stay tune!

Franchement, on est d'accord que le Breizh-T d'avant était LARGEMENT MIEUX QUE AVANT! Breizh Cola #ToutFoutLeCamp

Still looking for users feedback on Raven to move to an alpha! If you're working on a project that could use OCaml's type safety with Python-like ML capabilities, I'd love to support your use case and develop what you need. Reach out to collaborate on the first release!

If you're interested in editors and developer tools, consider applying to Jane Street! It might be an especially good fit if you're an excited vim or vscode user who would love working on making those experiences better for a den of functional programmers.

OCaml Web Development: Essential Tools and Libraries in 2025: Should you use OCaml for web projects? Web development trends are a hotly debated topic in the computer programming world and the familiar faces of languages and frameworks… dlvr.it/TKpX4t #OCaml #OCamlPlanet

🎥 Hear it from the creator of Scala himself! Martin Odersky is joining Lambda Days in June to share how Scala’s type system is evolving to make capability-based security both safe and ergonomic. Don't miss his keynote on rethinking access control in modern software systems. 🎟️

A new Signals and Threads just dropped, with Ian Henry! This one is about building tools for traders, but it also has some fun dives into Ian's personal projects, including bauble.studio and janet.guide. Anyway, more here: signalsandthreads.com/building-tools…

Is OCaml on the web? Absolutely! Our latest post introduces some of the top libraries and tools for web development in OCaml tarides.com/blog/2025-05-1…

A new random drawing :) In black and white, as always :S

Getting ready for the first alpha soon 👀 raven-ml.dev

Unnecessarily complicated machine. (Some old graffiti memories :D)

After 3 months building Raven Recurse Center, I'm raising funds to work on it full-time. Goal: Make OCaml a first-class citizen in the ML world. Looking for: • ML teams interested in OCaml • OCaml shops needing numerical tools RT appreciated to help me find sponsors 🙏 🧵

Make sure you catch Xavier Van de Woestyne and his talk: Build Systems, With Applicatives, Arrows And User Defined Effects ✨ youtube.com/watch?v=zHckNw…

"A bit like how React's functional patterns feel more at home in actual functional languages, Raven is becoming what I imagine Jax/Flax intended to be - clean function composition all the way down."

“Why do we need option types?”

See github.com/art-w/x-ocaml I wrote a short post about my experience playing around with x-ocaml in Jekyll kcsrk.info/ocaml/x-ocaml/… Works pretty well. Looking forward to writing interactive OCaml blog posts!
