We will go over how we build systems on Brex, why we don't use OTP for clustering and where we think it's the correct place to use it.

A big part of work there was data migration to Facebook data centers. This presentation is about the journey we went through to get there, challenges we faced and solutions we came up with. How to call into C++ from Erlang? How to copy data with no effect on production traffic? How to deal with cross-DC network cuts, server restarts, hardware losses, etc? How to switch users from one DC to another?

Since 2007 the firmware of the device is written mainly in Erlang - including protocol stacks for all existing automotive protocols. Peer is currently developing an industrial transport system controller with Erlang in a small embedded system. Peer's previous experience ranges from low-level device drivers to functional languages in industrial and automotive applications, he initially mastered in Physics at the Technical University Munich. He has been working self-employed as a developer since 1987 and also consulted in applied cryptography and protocol design and implementation.

Well, I did. And I was a nervous wreck! We were launching a new product during a commercial at the Super Bowl 302 days away, and I was betting everything on a technology we had never used in production. I spent countless nights wavering back and forth thinking about the millions of dollars and hundreds of thousands of person hours that were on the line. Everything was resting on the shoulders of this one web service that had to handle the excessive load placed upon it when our commercial aired. The technology chosen was Erlang, a mystical, functional, dynamically compiled language that was very foreign to this eight-time Microsoft MVP. This is a story about picking the right tool for the right job, exploring other possibilities, and the difference between playing with technology and putting it into production. As a noted storyteller, I'll take you on the journey of: · how we stumbled upon Erlang during our dedicated innovation time · what made it so special that we were willing to take such a risk · what we learned along the way · how it performed · and would we do it again If you love a great technology story, I hope you'll join me for this tale of how this web service, built in unproven technology to us, survived Super Bowl Sunday.

It takes a lot to support this statement. For 10 years WhatsApp demonstrated unprecedented reliability and availability, serving over 1.5B users. There is absolutely no way to reproduce interactions between all of them, within the cluster spanning over 10,000 nodes and multiple data centers. Investigations must be done on a live system without disturbing connected users. If there are repairs needed, it has to be done on the fly. This talk will guide through debugging and troubleshooting techniques used at WhatsApp. Maxim will share a few case studies, explain monitoring, introspection, performance analysis, and tools. Some knowledge of Erlang and C is necessary. Read the full abstract: https://codesync.global/speaker/maxim-fedorov/ --- THE SPEAKER - MAXIM FEDOROV Impossible takes a little longer Maxim Fedorov is a software engineer at WhatsApp, the largest messaging app. Maxim’s work is focused on performance and scalability of the server side.

The general explanation for them is usually along the lines of """"they're like interfaces for OOP"""". While that's somewhat accurate, it's also misleading and introduces a lot of confusion on how and when to use the existing behaviours and when it's reasonable to define your own ones. In this talk, Brujo will explain what behaviours are, how they should be used, and how to create and expose new ones if you ever need to.

Let me entertain you with my journey to build an Erlang client as a part of a globally distributed feature management platform by LaunchDarkly. We'll start with an overview of how feature flagging works, including architecture of LaunchDarkly service. Then we'll focus on building an Erlang application, covering non-trivial role LaunchDarkly SDK clients play as a part of a distributed feature flag database. We'll draw parallels to other languages for extra fun too. Read the full abstract: https://codesync.global/speaker/zurab-davitiani/ --- THE SPEAKER - ZURAB DAVITIANI Feature flagging enthusiast, wrote an Erlang/Elixir SDK client for LaunchDarkly.
