Akka and Kotlin coroutines: ♡

I've experimented with Kotlin and coroutines in programming Akka. And I must say, I really like the combination so far.
But before I go into it some brief preliminaries for those who don't know Akka and actors.

Actors and Akka

Actors are a programming model that fits cloud native architectures particularly well. Being highly available and scaling horizontally. All while embracing the realities of multiple servers collaborating, server instances coming and going and the network having hickups.

On the JVM Akka is the prominent actor framework. It's been around for a while now and as a result it's highly reliable, well thought out and offers a wide programming eco system. My own interest in Akka is because of its suitability for software systems that can only be built with business events as a key construct and thinking model. And then of course materialized views, CQRS and near real-time data streams play a big role in constructing those systems.

Using Elixir releases and multi-stage Docker files to simplify Phoenix deployment

This repo is my experiment in deploying a basic Phoenix app using the release feature from elixir 1.9 (https://elixir-lang.org/blog/2019/06/24/elixir-v1-9-0-released/) and docker, via a multi-stage Dockerfile (https://docs.docker.com/develop/develop-images/multistage-build/) leveraging bitwalker's docker images for Elixir and Phoenix.

Step 1: Install Elixir 1.9.1 (and Erlang)

The simplest way to manage Elixir versions is to use asdf.

// BrowserRouter is the router implementation for HTML5 browsers (vs Native).
// Link is your replacement for anchor tags.
// Route is the conditionally shown component based on matching a path to a URL.
// Switch returns only the first matching route rather than all matching routes.
import {
  BrowserRouter as Router,
  Link,
  Route,
  Switch,
} from 'react-router-dom';

Profiling performance

Using perf:

$ perf record -g binary
$ perf script | stackcollapse-perf.pl | rust-unmangle | flamegraph.pl > flame.svg

NOTE: See @GabrielMajeri's comments below about the -g option.

Rust/Haskell: Higher-Kinded Types (HKT)

A higher kinded type is a concept that reifies a type constructor as an actual type.

A type constructor can be thought of in these analogies:

• like a function in the type universe
• as a type with a "hole" in it
