How to Sell Elixir AGAIN (2023)

Presented by Evadne Wu at Code BEAM Lite in Stockholm, Sweden on 12 May 2023

Synopsis

We have celebrated 10 years of Elixir and also nearly 25 years of Erlang since the open source release in December 1998.

Most of the libraries that were needed to make the ecosystem viable have been built, talks given, books written, conferences held and training sessions provided. A new generation of companies have been built on top of the Elixir / Erlang ecosystem. In all measures, we have achieved further reach and maturity than 5 years ago.

How to use this gist

You've got two main options:

ttesmer

{-# LANGUAGE TypeSynonymInstances #-}
data Dual d = D Float d deriving Show
type Float' = Float

diff :: (Dual Float' -> Dual Float') -> Float -> Float'
diff f x = y'
  where D y y' = f (D x 1)

class VectorSpace v where
  zero  :: v

kpmcc

// preprocessor macro - basically copies tree.h and puts
// the contents where the include goes
#include <stdio.h>
#include <stdlib.h>

#include "tree.h"


int print_tree_hello() {

58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}

package main

import (
	"context"
	"flag"
	"fmt"
	"log"
	"net/http"
	"os"
	"os/signal"

let recv = (client, maxlen) => {
  let bytes = Bytes.create(maxlen);
  let len = Unix.recv(client, bytes, 0, maxlen, []);
  Bytes.sub_string(bytes, 0, len)
};

let parse_top = top => {
  let parts = Str.split(Str.regexp("[ \t]+"), top);
  switch (parts) {
