About rlander

Rodrigo Landerdahl

Polyglot programmer from Florianópolis, Brazil.

Interested in fringe programming languages like OCaml, F#, Elm, Erlang, Clojure and Prolog. But I've been known to dabble with Python, Ruby, JS and even Smalltalk (which I enjoy very much).

    Except const is not sufficient. It will prevent the reference from being reassigned but the const can still reference a mutable object.

    Maybe you haven’t seen this yet, but there is a (recent) option to fork a conversation when you click on the thee dots of a reply.

    True, but GDP is often a decent proxy for material living standards, especially across countries and over time (so long as we note what it leaves out).

    That’s not a small cycle count for a normal household. 90 × 24 = 2,160 total hours. I sous vide now and then, about twice a week for 6 hours each, so around 12 hours a week. That w…

    > if Imba offers a new approach it fails to communicate this on the landing page and focuses on code compression instead. Fair enough. While it does touch upon `memoized DOM`, you'…

    I feel like you missed the point of Imba. It's not solely focused on code compression (although that does appear to be a secondary objective). Instead, Imba is all about empowering…

    Opa was ahead of its time by at least 10 years. Have you seen Electric Clojure [0]? [0] https://github.com/hyperfiddle/electric

    What an amazing story! I have to admit, I was a bit apprehensive while reading through it.

    Does that apply to neutered males?

    That’s weird. We moved to a new house and I was surprised one morning to see the cat scratching the upper balcony door, waiting to be let in, even though he’d never used that parti…

    How is Elixir’s design different from Erlang’s? Semantically they’re pretty much the same language. A better example would be Java/Clojure.

    You’re missing the crux of the argument: auto-currying. In languages like Elm and Ocaml all functions are single arity which means a multi-arity function is just a partially-applie…

    IME it is. Many Elixir apis end up forcing an unnatural parameter order just so that the entire body can be piped through. Clojure is way more consistent in this regard: - thread f…

    Well I believe that no pipe is better than a a handicapped pipe operator. The Elixir implementation inverts the classical order of piping last in functional languages to the detrim…

    Why I choose Erlang: - simpler syntax: there’s no Erlang program that you can’t read after getting comfortable with the language. Seriously. Go read OTP source or Ryaks, everything…

    Please don’t listen to the peanut gallery. The re-frame docs are in a league of their own and most of us appreciate the enormous effort put in to make them awesome. Keep rocking.

    That side table is amazing. How did you learn woodworking? I’ve been meaning to get into it but have no idea where to start.
