Code BEAM America 2024

✨This keynote talk was recorded at Code BEAM America 2024, a conference by Code Sync https://codebeamamerica.com ✨ Elixir embraces a fascinating mix of types, features, and libraries to build a surprising breadth of concurrent libraries and services with stunning reliability and concurrency. This talk allows a peek under the hood at how Nerves, LiveView, NX, LiveBook, and more push Elixir and yet provide a natural, coherent development experience. Behaviours in OTP establish contracts for inversion of control. Phoenix and LiveView take advantage of the same behaviours and also use macros to provide a uniform, concise usage model and adds macros to hide ceremony while surfacing beautiful user experience that remains correct under pressure, from templates to infrastructure Come find out how Elixir's most loved frameworks and tools got that way, and the Elixir tools that make those frameworks both beautiful and right.

✨This keynote talk was recorded at Code BEAM America 2024, a conference by Code Sync https://codebeamamerica.com ✨ Abstract: This presentation charts the evolution of the BEAM virtual machine over 30 years, focusing on its concurrency model and its role in fostering robust, fault-tolerant systems. It will cover the progression from Erlang's implementation in Prolog to the creation of JAM and the subsequent development of the BEAM. The talk will include technical experiences from Klarna, highlighting how BEAM’s architecture supports efficient and reliable concurrent programming. It will give you insight into how to think when developing concurrent programs. Let's stay in touch!

✨This talk was recorded at Code BEAM America 2024, a conference by Code Sync https://codebeamamerica.com ✨ Contributing to the Erlang Ecosystem: My Journey from Individual Contributor to Maintainer Lately the Erlang Ecosystem has grown to address many new domains. But is its community growing enough to support it? My experience as a new contributor may shed light on this. I'm a 16 year old student who started contributing to the Livebook, Hexpm and Nx projects at 14. Since then I've grown from being a raw newbie to receiving funding from The EEF to work on packages that will support Erlang's telemetry implementation. Join me as I talk about my challenging transition and see how I: - overcame my fear of the opensource community - learned to work with other members - found more meaningful ways to contribute - learned to balance my contributions with my other priorities If you're new to the community, you'll learn how to get started and grow in the community - even if you have as little experience as i did. Maintainers will see how the community helped me to make valuable contributions, how it got in my way, and how my experiences can help their projects. Let's stay in touch!

✨This talk was recorded at Code BEAM America 2024, a conference by Code Sync ✨ https://codebeamamerica.com Gleam is a programming language that makes the case for type safety in the BEAM. Give it a try and you will soon discover that the straightforward syntax and great error messages give you the power to start building your domain logic behind a lovely typed foundation. It is a great choice for simple finite programs that will not break, but the BEAM offers much more than that... Its process primitive gives us the means to model asynchronous and concurrent work. Gleam offers a way to represent processes and messages within the type system and uses that to rebuild one of the fundamental abstractions of OTP an Actor. In this talk we’re going to disassemble what makes an Actor and what it takes Gleam to make it work along its type system. Let's stay in touch!

✨This talk was recorded at Code BEAM America 2024. Check out our next event: https://codebeamamerica.com ✨ Hyper-Q is a database virtualization application written in Erlang. It emulates the syntax and semantics of a guest database over a host database, which involves cross-compiling SQL from one dialect to another. Additionally, it emulates functionalities that are not offered by the host database. Tuning Hyper-Q for new SQL workloads involves identifying bottlenecks in the cross-compilation process. This presentation will provide an overview of the diagnosis process for identifying bottlenecks through profiling and will also focus on some architectural changes made to address them. The main objective of this initiative was to reduce memory consumption during processing, thereby improving the throughput of queries that can be processed through Hyper-Q. This, in turn, assists customers in transitioning from legacy data warehouses to cloud databases with minimum need for application rewrites saving time and effort. Let's stay in touch!

Check out info about our upcoming event: https://codebeamamerica.com ✨ This talk is about lessons, unexpected benefits, and areas for improvement from deploying Elixir and Erlang/OTP on custom hardware running Nerves at SmartRent. SmartRent provides smart home features to rental properties and uses Nerves in smart thermostats and IoT gateways. While we create our own custom hardware and use many Nerves features, this talk is less about that and more about how we’ve ended up using the BEAM. In many ways, it’s a reflection on why we chose the platform in the first place. The talk starts with describing the types of devices we build and constraints we have with our embedded processors and our deployment environment. OTP comes to the rescue with solutions, and as countless others have, we’ve had a journey of discovery of functionality that we had in the beginning. Even if you’re not an embedded developer, my hope is that you’ll gain appreciation and insights into developing applications on the BEAM based on our experiences at SmartRent. Let's stay in touch!

This is a wild ride through a project my team undertook to improve XML parsing in Elixir for large payloads by 10x. The approach taken marries a few different ideas but also introduces a parsing approach that slims down the amount of parsing that needs to happen by ignoring data that has not been previously specified as expected. This has good consequences for security as well as performance as I will outline. Afterwards I extend the idea to JSON parsing with interesting consequences. Let's keep in touch!

None of the existing libraries in the BEAM ecosystem fulfilled the needs of the team, and it was estimated that contributing new changes to those projects would be very difficult. At the same time, writing and maintaining a client from scratch would require a lot of time, much more than the team could afford.

Erlang is great at moving data around. Why is it so hard to mesh the two of them together? Many projects use relational databases in only the simplest way, through simple templating libraries, or custom code, forgoing the power of the relational database. Is there a better way? We'll survey some of the technology pieces such as ODBC, dispel some misconceptions, and explore the awkward impedance mismatch between Erlang and relational databases.
