Crate im — Immutable Data Structures for Rust
▻https://clojurust.github.io/clojurust.doc/im#clojure #rust #immutable #dataStructures #amazing #bodil
« This library implements several of the more commonly useful immutable data structures for Rust.
What are immutable data structures?
Immutable data structures are data structures which can be copied and modified efficiently without altering the original. The most uncomplicated example of this is the venerable cons list. This crate offers a selection of more modern and flexible data structures with similar properties, tuned for the needs of Rust developers.
Briefly, the following data structures are provided:
Vectors based on RRB trees;
Hash maps/sets based on hash array mapped tries;
* Ordered maps/sets based on B-trees.Why Would I Want This?
While immutable data structures can be a game changer for other programming languages, the most obvious benefit - avoiding the accidental mutation of data - is already handled so well by Rust’s type system that it’s just not something a Rust programmer needs to worry about even when using data structures that would send a conscientious Clojure programmer into a panic.
Immutable data structures offer other benefits, though, some of which are useful even in a language like Rust. The most prominent is structural sharing, which means that if two data structures are mostly copies of each other, most of the memory they take up will be shared between them. […] »

Learn Functional Programming without all that Arcane Math Jargon Nonsense SpellCasting PhD Jive Talk

Transitioning from OO to FP is difficult. I know it’s difficult. We can do this. We’ve done difficult things before.And if you’ve never programmed before?— Phew —You won’t have to be retrained.In fact, given that beginner developers don’t have to displace a long history of ingrained inert ideas, they’re actually becoming the world’s best developers seemingly overnight.

Cognitect Vase – Unlocking hidden value in your data ▻http://blog.cognitect.com/blog/2017/1/30/unlocking-hidden-value-in-your-data-1
« Vase is a library for writing declarative, data-driven microservices. A single HTTP service, complete with database integration and data validation, can be created within minutes.
We achieve this acceleration through Vase’s declarative nature- Vase does all of the mundane data-plumbing of a service, so you can focus on delivering value to your customers. The microservices we build with Vase easily evolve and grow to meet new business demands. Individual teams can each evolve their Vase services independently, ensuring that no team is blocked from delivering value. […] »

Un de mes « souhait » pour 2015 est de découvrir un peu plus de #programmation_fonctionnelle (un autre étant de faire moins de « technique » dans mon boulot... oui oui).
Mais, ça m’intéresse, car je me suis aperçu que ce sont les aspects « fonctionnels » de JS qui m’ont un peu redonné goût à la programmation.Par contre, ce paradigme de programmation — qui est en train de devenir très « hype », j’ai l’impression — est réputé très difficile et exigeant (parfait pour le « dyslexique des maths » que je suis... ironie inside).
J’ai essayé quelques tutos (#ClojureScript, un « Lisp »), j’ai une connaissance qui est à fond dans #OCaml (hello @nukiFW), et j’ai posé quelques questions.
On m’a recommandé :
– « Introduction au langage OCaml » : ▻http://form-ocaml.forge.ocamlcore.org/intro.html
– « OCaml from the very beginning »
– « Real world ocaml »Bref, si vous avez des conseils sur le sujet... je prends tout :)
Il me reste à me trouver une petite idée de projet motivant et sympathique (un truc visuel, poétique et/ou inutile) pour jouer.-

Overtone is an open source audio environment designed to explore new musical ideas from synthesis and sampling to instrument building, live-coding and collaborative jamming. We combine the powerful SuperCollider audio engine, with Clojure, a state of-the-art lisp, to create an intoxicating interactive sonic experience.
Grosso modo, c’est un front-end en #clojure pour #supercollider
Je vais essayer de jouer avec et voir si ça peut remplacer #puredata pour l’utilisation que j’en ai. Il va falloir que je finisse de me muscler en #programmation_fonctionnelle...
