Elixir Sydney is currently teamed up with Elixir Melbourne to form Elixir Australia, your one stop-online meetup for all things Elixir in the land down under!

Welcome to our first meetup for 2021! Still online for the time being, but our awesome community still shines brightly with a great set of talks to kick off what surely will be a better year than the last:

-- Presentations --

Sensors, Beers and Nerves

  • Fiona McCawley :: @saucerlike

After recently getting into brewing beer and wanting to learn more about programming hardware and sensors, this talk is about a small project in setting up a Bosch BME280 temperature sensor using Nerves and a Raspberry Pi Zero W, and monitoring and displaying the data.

Safe-ish: A BEAM-bytecode-level-load-time-sandboxy-library-thing

  • Robin Hilliard :: @robinhilliard

Safe-ish is an experimental sandbox for BEAM modules that examines and rejects BEAM bytecode containing instructions that could cause side effects. You can provide an optional whitelist of opcodes and functions the module can use.

https://hex.pm/packages/safeish

In this talk Robin will talk about his summer holiday project, or what happens when you put a series of 100 USD bounties to break your library up on the Elixir language forums. It also talks about the beam file format and writing a rudimentary BEAM file disassembler in Elixir using binary pattern matching.

-- Lightning Talks --

Exercism: Pascal's Triangle

  • Nick Bosch :: @nicholasbosch

Nick will walk us through his solution to Exercism's Pascal's Triangle problem (https://exercism.io/tracks/elixir/exercises/pascals-triangle).

A Zoom link to the meetup is provided closer to the date of the meetup, so keep an eye out for when it drops.

Hope to see you on the internets!

Paul, Josh, and James
