As the first alpha version of RavenML is practically out, I'm currently working on refactoring and migrating the entire codebase of SoundML to RavenML. I'm hopping that this significant change to a more modern scientific computing library will solve tons of issues I had wth Owl.

Thanks to @ChShersh for giving me the idea @yawaramin for helping me understand how can I write unit tests in OCaml @onehappyfellow for sending me over 20 janestreet repos, showing me how to metaprogram in OCaml and confusing me even more

Hannes and his peers made their dream a reality by founding a worker-owned collective to write OCaml and they've been busy building useful things for the ecosystem and for their clients! 🐫🔥

I had a lot of fun giving this talk in Singapore about the many-years-long saga of multicore OCaml, and in particular, the work over the least 2.5 years of getting it ready for production work within Jane Street's walls.

@sabine_s_ Lookit! OCamel ftw!!

I'm currently being mind blown by the amount of work put into RavenML. Huge thanks to @tmattio_ for his work, I'm sure this will have an insane impact on the whole OCaml ecosystem.

Things I have learned in 10 or so hours I have spent learning OCaml: - I am surprisingly good at writing recursion, it seems that learning Gleam beforehand helped a lot - OCaml ability to infer function types is refreshing, and doesn't feel limiting at all

What made you fall in love with functional programming?

every language gets the heroes it deserves?

man, I'm looking forward to just always use Dune package management 🥹🐫🔥

reasonable practice I feel like dune evolving to be a unified frontend for OCaml, just like cargo, is a good thing means that some things can be reimagined and built to be fast (e.g. package management, compiler / tool installation)

recently, we've spent some time migrating the official OCaml website to use Dune package management, and it feels ready there's just a few things we need to address / resolve in order to make this the default build setup github.com/ocaml/ocaml.or…

don't ask what ocaml can do for you ask yourself: what can I do for ocaml?
