Erlang is getting pretty!

How much time did you spend today reading code? How many times did you have to look harder because of how the code looked?

Maintaining a clear and consistent code style is hard: manual inspections often leads to endless bikeshedding and linters add noticeable overhead to the workflow. Many languages solved this issue through automated code formatters - Go, Rust, Elixir, Elm among many others. And now, thanks to the new erlfmt tool, Erlang is getting pretty as well!

Come to this session to learn more about erlfmt - how it works and how it can help your team.

THIS TALK IN THREE WORDS

Erlang

Tooling

Developer experience

OBJECTIVES

  • Introduce the audience to the concept of algebra-based pretty printing
  • Explain how an automated code formatter can streamline developer experience for teams and in open source

TARGET AUDIENCE

Erlang programmers of all levels

From Elixir to Erlang - experience report

Is the tooling in Erlang really that bad? Are macros in Elixir actually creating that much confusion? And what about the syntax? Over the last couple months, I worked almost exclusively with Erlang after many years spent with Elixir. In this talk I'm going to share my reflections on the state of both languages and what they can learn from one another. I'll explore things that I found surprising, some that I miss, and couple that were delightful.

OBJECTIVES

Compare and contrast experience of using Elixir and Erlang in a work environment.

What actually is the BEAM?

At this conference, we're surrounded by the word "BEAM". A quick exploration will reveal it has to do with how Erlang code is executed and is the secret sauce uniting all of us - Erlang, Elixir, LFE, Efene and others. But do you really know what it is? In this talk, Michal will carefully explore the BEAM, both the runtime and the compiler. We'll see how they relate, what particular strengths this gives to our code and how we can leverage it from the applications we write every day in Erlang and Elixir. Finally, we'll see how the BEAM is similar and different to other environments and languages like Java's JVM, C#'s CLR or Lua.

Elixir ecosystem / Elixir core team updates

What's new in the Elixir ecosystem? Also, updates on what the Elixir team has done in the last few months, what are the projects they're working on, what's going on on the research side, and what features will be in the next release.

Optimizing for the BEAM

The BEAM is a wonderful piece of technology that we all love and use daily when writing our programs - no matter the language!

For the past year, Mikhal has worked on optimising a couple of open source libraries, building performance-focused applications and contributing several optimisations to the Erlang compiler and the BEAM runtime. During this presentation, he'll share his discoveries and what he has learned.

He'll explore some common techniques for optimising programs running on the BEAM, applicable to Erlang, Elixir and LFE. He'll show us what tools can be used to evaluate performance and discover bottlenecks. He'll then talk both about how these problems can be solved - both by optimising the pure functional parts, leveraging the knowledge of BEAM innards, and by optimising concurrent programs around processes.

OBJECTIVES

In this talk, the audience will learn about:

  • tools for evaluating the performance of BEAM programs
  • techniques for pinning down particular efficiency issues
  • common techniques for optimising functional programs and concurrent applications
  • possible future changes to the runtime and compiler focused around performance
