The Soul of Erlang and Elixir - Saša Jurić - GOTO 2019

rodrigues

Whether you’re developing a small web site or a large-scale distributed system, Erlang and Elixir are great tools for building server-side systems. Both languages can help you start quickly and deal with highly complex problems at a large scale.

This talk aims to explain what makes Erlang and Elixir suitable for such tasks. We’ll look past the syntax and the ecosystem, focusing instead on the concurrency model of these languages.

Combining a bit of high-level theory and a couple of demos, we’ll examine some important properties of Erlang/Elixir concurrency, with a special emphasis on why these properties are very relevant when building highly available systems.

The talk targets experienced backend developers, but no knowledge of Erlang or Elixir is required. You will walk away from the talk with a better understanding of what distinguishes Erlang and Elixir from the rest of the pack, and why these languages are very compelling choices to power your next software system.

I am only at 16 minutes right now but I am starting to send it to everyone I know. If that doesn’t convince people from BEAM/Erlang/Elixir, I don’t know what will. Thanks for the talk @sasajuric !

I’ve watched a bunch of videos on this topic and that was the clearest and most concrete example I’ve seen yet. I was actually disappointed the video ended, it was that good. I like how it was just packed with actual examples, with little to no fluff, and the presenter talks fast and to the point (in a good way). It feels like you got 3 hours of information in ~40 minutes.

@sasajuric any chance you provide the related example code from the presentation in a repo?

When I first introduced Elixir to the company I am part of about 1.5yrs ago a big part of my research into solutions/languages was around what made sense for our engineering team from a team size, company need, where we want to be in 4yrs perspective. The last part of your presentation really hit at what I perceived as huge benefits then and now.

Thanks for all the contributions you give to the community.

Yeah, the demo code would be nice. I liked the stats page with the live charts.

I was secretive about it because I don’t think the code is pretty, so I wouldn’t suggest it as an inspiration on how to write production Elixir

That said, in case you want to take a look at the code, the repo is already publicly available here. The main site is in the example_system folder.

Just say it’s not the most pretty and accept PRs

Nice and dense talk @sasajuric, seeing how one debugs a live BEAM system is such a pleasure every time!

PS. I noticed that in your vscode that you didn’t have coloring for atoms. Perhaps it was a new installation just for your demo, but in case you or anyone else cares how to add those I’ll just point you to this gist Visual Studio Code settings for coloring additional Elixir-specific symbols (from my dark theme, but one can always experiment with the colors) · GitHub (make sure you have an Elixir plugin like vscode-elixir-ls installed and then add the extra configuration to your settings.json)
