Elixir Australia July 2020

Welcome to the July edition of Elixir Australia! Come and join us for some fun-ctional edutainment, and get happily distracted from all the other stuff that is keeping us all indoors these days.

For tonight's talks, we have:

---

Newton Slug Kilowatts
Robin Hilliard :: @robinhilliard

It's easy to make mistakes with measurement units, especially when you're mixing imperial and metric. My (second) attempt to dealing with this problem is a 400ish line module that lets me write stuff like this:

iex> use Unit
iex> {1, :m} * {200, :cm}
{2.0, :m2}
iex> {61, :s} - {1, :min}
{1.0, :s}
iex> {9, :ft2} / {1, :m}
{0.8364312267657993, :m}

In the talk Robin will cover:

Simple Elixir data structures that model relationships between units (inches, cm, feet are all lengths) and dimensions (length, area, time, acceleration, power, ...)
A technique for handling distinct error cases in with statements and
Show how straight forward it is to extend the built in arithmetic operators in Elixir.

Massively Multiplayer Clicking With Phoenix LiveView
Julian Doherty :: @madlep

Julian will do a code walk through of how to put together a simple real time multiplayer clicker game with LiveView. This is an extended version of a lightning talk on LiveView he did at work at Envato.

Look forward to seeing you there!
