THEMES

THE BEAM

Learn from the leading experts and Erlang committers about new language constructs, VM implementations, and powerful libraries which form the Erlang eco-system. You will learn how many of its features work and how to best use them to write fast and efficient code.

SCALABILITY AND RELIABILITY

Scaling has been a given for many years now and the BEAM supervision concepts are well understood. But you need more, much more. You want to build distributed clusters of massive potential, you want to monitor your systems and automatically provision replacement hardware in case of failures. What is best-practice? What are the big players doing? How do you ensure you don't have to wake in the middle of the night?

TOOLS

It's not always clear what off-the-shelf software is useful in production-quality systems. In the tools track, you will learn what existing production systems' maintainers are using to monitor and test their systems via war stories and experience reports of novice and expert users.

FRAMEWORKS

In the frameworks track, you will learn from the leading experts and committers about new and leading frameworks such as Phoenix, MongooseIM, Nerves and RabbitMQ. You will find out how these frameworks work, how to best use them and where not to use them.

WEB & APIS

With recent innovations the BEAM is now suitable for rapid web application development and gives any of the established frameworks a run for their money. Much work has been done to integrate with cloud providers such as Google and Amazon, and containerisation such as Docker and Kubernetes. The BEAM of 2019 can control your infrastructure, write Google documents, and is ideal for integrating with 3rd party services such as machine learning, and payment providers.

CASE STUDIES

Every new domain that Erlang and Elixir push into brings a new class of problems and a new class of solutions. In this track, we'll learn from other's experience, where things have been peachy and where they haven't been so much. We'll all walk away with a more clear idea of how to build highly reliable software.

INTRODUCTION TO ERLANG AND ELIXIR

New to Erlang and/or Elixir? Interested, but don't know quite where to dig in? We've all been there! In this track, you will learn from other's experience, get a sense of the lay of the software ecosystem, get help from the community and contribute back for everyone's benefit.

Code BEAM STO is a vibrant space where the best of the industry and community gather to rocket the BEAM ecosystem.

Code BEAM STO is a great place to meet others in the community who may be doing similar things to you or something so radically different that it inspires you to new heights.

It is implemented with NIFs on the Unix networking functions, which gives programmers access to _all_ of the socket functionality in the OS networking stack. Overview of the API, implementation how the new sockets is intended to fit in the rest of Erlang/OTP. Intermediate #BEAM	Alexandre Rodrigues Track 2 How a startup survived the hype years of NoSQL Kivra Loves Erlang Alexandre Rodrigues Kivra AB. 2012, the NoSQL hype was strong, a digital mailbox service called Kivra is launched and the choice of database was Riak and the language was Erlang. Today, Kivra is the most used digital mailbox in Sweden. How did the prototype become a reliable system capable of handling changes in terms of time, functionality and load? #Case studies	Benoit Chesneau Track 3 From the idea to a MVP in less than 3 months MVP Pattern OTP Benoit Chesneau Enki Multimedia. What does it mean to develop and deploy products or services written in Erlang on a daily basis? How can you build a product using multiple linked processes or services on one or more machine that will fit your business? How can you provide an MVP or a pilot in less than 3 months?

18.25 - 19.05	Sonny Scroggin Track 1 Don't write NIFs (at least not in C) Native Safety Performance Sonny Scroggin Bleacher Report / Rusterlium. Most experienced Erlangers will caution against writing NIFs, and for good reason! NIFs are notoriously dangerous. Not only do we have to worry about crashing the BEAM, but we run the risk of degrading the scheduler if we're not careful. But what if writing NIFs were safe? In this talk, Sonny will discuss Rustler, a library which makes it incredibly simple to write safe NIFs in Rust. #BEAM	Timmo Verlaan Track 2 A war story - from failures to success Failures Learnings War story Timmo Verlaan Enreach. Developing a communication platform seems to be the perfect fit for the BEAM. At least, that is what we thought when we set out to replace the existing Astrisk-based platform. Picking the proper tools is a good start, but when you develop in isolation for 2-3 years you might not learn about the BEAM characteristics under load. After 6 months in production, the first warning signs started to show. #Case studies	Marc Sugiyama Track 3 Unicode, Charsets, Strings, and Binaries Character sets Character encoding Clarity Marc Sugiyama Datometry. Writing global software means our programs need to speak global human languages. UTF8, latin1, Unicode? And what does Erlang do? This talk demystifies the terminology around character encoding, explains how to retrofit your Erlang program for Unicode using Datometry HyperQ as a case study, and gives some best practices to help you break the one-byte/one-character assumption. #Introduction to Erlang & Elixir

But with the 'releases' support introduced in Elixir v1.9, it has become seamless. Since everybody likes containerising their apps, we'll also try to containerise our releases and deploy on to our most loved cloud service(AWS). Intermediate #Scalability & reliability	Edmond Begumisa and Roshan Giri Track 2 Flamegraph and heatmap profiling. Profiler Heatmaps Flamegraphs Edmond Begumisa Medical Objects Pty Ltd.. Profiling Erlang systems is tricky due to their concurrent nature. new open-source low-overhead profiler which samples callstacks and graphically categorises them by process status, reductions, memory and message queue length over time making it easy to identify code where time and memory is being spent. identify both sequential and concurrency bottlenecks in our Erlang Healthcare HL7 message processing system. Advanced #Tools	Chaitanya Chalasani Track 3 Mnesia as a complete production database system The Understated Mnesia Chaitanya Chalasani Access Europe GmbH. Mnesia is often underplayed as an in-memory cache and is seldom used alone in production. The first part of the talk is to present few case studies of using only Mnesia as the production database engine for large throughput services. The second part of the talk is to present an open-sourced framework for Mnesia (Tivan) which is a collection of utilities and behaviours that enriches its role as a prime database engine.

A lot of legacy is thrown out and new mechanisms will replace old flawed ones. Most of the TLS handshake will be encrypted as opposed to earlier when most of the first handshake was in plain text and encryption started first when sending the final handshake confirmation message. TLS-1.3 also puts new requirements on TLS-1.2 to pave the way for migration. Intermediate #Frameworks
