CodeBEAM US 2022 :: Thursday Schedule

Topics

12:00 PM - 01:00 PM

Keynote

Title: Welcome + Keynote: We are stronger together

Speaker(s): Maxim Fedorov, Andrea Leopardi

Topic: History & Philosophy of the Ecosystem

Tags: Introductory

The BEAM is living its best days. The ecosystem is thriving, big companies are picking up our languages, innovation is sprawling, and BEAM-based solutions are getting traction in new domains.

But being fragmented, the ecosystem is not as strong as it deserves. There are over 30 languages speaking BEAM, yet only a few can talk to each other. While improvements to Erlang/OTP often trickle down to Elixir and Gleam, the opposite is rarely true. Rewriting everything with Erlang is not an option - we would not rewrite C++ in C either. So what can we do to bring the community together?

We want to talk about the challenges we are facing, the future we envision, and some ideas on how we can step into that future. We want to get you inspired to reunite the ecosystem.

01:05 PM - 01:20 PM

Keynote

Title: OTP update

Speaker(s): Kenneth Lundin

Topic: Innovation

Tags: Introductory, Virtual

Update from the OTP Core Team.

01:20 PM - 01:50 PM

Coffee Break Teller Challenge: Do you have what it takes to crack the Teller Bank app?

01:50 PM - 02:35 PM

Track 1

Title: Network Observability at LinkedIn

Speaker(s): Ananya Shandilya

Topic: Growth

Tags: Intermediate, Virtual

The LinkedIn infrastructure has thousands of services serving millions of requests per second. At this scale, various kinds of data points must be collected, processed and observed to maintain the health of the infrastructure - one of them is network flows. Our infrastructure components export flows at the rate of 2M packets per second. This talk describes a data collection, processing and storage system for network flow data written in Erlang. It gives an overview of the system’s architecture and some of the interesting challenges we faced while scaling this system.

Talk objective(s): Share the details about the data processing system we built at LinkedIn using Erlang for collecting and processing high volume and velocity of network flow data Target audience: Erlang developers / Observability engineers / Backend engineers

Track 2

Title: Refactoring via the Language Server Protocol

Speaker(s): Simon Thompson, Dominik Katkó

Topic: Innovation

Tags: Introductory, Virtual

Refactoring is the process of improving code without changing what it does, and is typically supported in tools such as Wrangler for Erlang. The Language Server Protocol (LSP) allows tools like this to be integrated in a variety of editors, including VS Code, emacs and vim, and the Erlang Language Server (ELS) provides an integration of Erlang into LSP.

After a short introduction to refactoring, Wrangler and Erlang LS, we explain how facilities in Wrangler, including refactorings, input and form-based choices, are incorporated into ELS and LSP, and demo these for a variety of Wrangler refactorings.

Talk objective(s): The talk will introduce refactoring and Wrangler to a new audience of coders who might use ELS as part of their daily practice. It will also show how the Wrangler Language Server can be used, and point out how to overcome its imperfections, and how it might be enhanced.

Target audience Any Erlang user

02:45 PM - 03:30 PM

Track 1

Title: Accessible Time-Series data with TimescaleDB

Speaker(s): David Lucia

Topic: Innovation

Tags: Intermediate

Timeseries data is everywhere! Whether you’re tracking application metrics, financial price information, or IOT sensor data, having an effective means to store, analyze, and display this can add value to any product. However, having an accessible timeseries database can be a challenge, with many proprietary databases requiring licenses, infrastructure costs and maintenance. TimescaleDB is an open-source alternative that is simply a Postgres extension, a database that many developers are already using. In this talk, we will look at what problems are needed out of a Timeseries database, and how TimescaleDB can help you solve these problems with familiar tools that are easily accessible on the BEAM.

Talk objective(s):

  1. Teach the audience where they might encounter timeseries data in their product
  2. Introduce TimescaleDB, how you can deploy it to your existing Postgres deployment
  3. Share ways of leveraging the unique features of timescale DB, including compression, continuous aggregates, and other features to build interesting applications on top of this data platform.

Target audience: Developers who may have timeseries data in their product, but have no found effective ways to utilize it, or are struggling with scaling timeseries aggregations

Track 2

Title: Building blocks and how to use them: a MongooseIM case study

Speaker(s): Nelson Vides

Topic: Growth

Tags: Intermediate

This is a talk about open source and the community, with MongooseIM as its backbone. MongooseIM is Erlang Solutions’ robust, scalable and customisable messaging server, and using it as a “case study”, I want to tell the story of the evolution of a big and old open source project. I’ll start presenting common Erlang design patterns for a server - the supervision trees, the many processes, the NIFs when they are needed, and most importantly, the ways to preserve a big project manageable and continuously evolving.

I also want to present the libraries that branched off from MongooseIM. In the evolution of a big project, often times you find pieces of code that are not an integral part of the business logic but actually can be generalised and reused for projects potentially very different from your own. I want to present what we found and how, what we extracted, and what we prepared for other people to reuse.

Talk objective(s): To present MongooseIM in three aspects: an Erlang codebase, an Open-Source project, and a messaging backend. To present the libraries that branched off the main project, together with how-tos and whys, that can be reused by other projects. Ideally, to get diverse developers interested in diverse pieces of code they can reuse in their projects and contribute to, and inspire developers to extract from their projects what is generic and find a way for other people to be able to reuse them.

Target audience: Probably developers of all backgrounds and interests.

03:40 PM - 04:05 PM

Track 1

Title: Build animatronics with Nerves

Speaker(s): Flora Petterson

Topic: DevOps

Tags: Introductory

The Nerves platform, framework, and tooling provide a highly specialized environment for using Elixir to build advanced embedded devices in industries worldwide. But can Nerves also make a puppet dance?

In this talk, I’ll share my experience as a second-generation puppeteer building interactive animatronics with Nerves. If you’ve ever wanted to automate a lawn decoration, create a haunted house in your garage, or code a small, silly project to give someone joy during a challenging time, this talk may be for you.

Target audience Anyone interested in Nerves, IoT, or puppetry

Track 2

Title: seL4 and BEAM: a match made in Erlang

Speaker(s): Ihor Kuz

Topic: Innovation

Tags: Intermediate

Erlang and Elixir can be used to develop robust and highly-available embedded applications with effective fault-tolerance, but the BEAM virtual machine still relies on the underlying operating system to provide a security and robustness foundation which can be insufficient when the OS cannot prevent other components from crashing the system.

The seL4 microkernel is a formally verified operating system kernel designed for embedded systems. seL4 provides isolation mechanisms that can prevent errors or attacks from spreading to other components but it expects each component to mange its own error detection and fault recovery.

I will demonstrate how combining the seL4 microkernel and the BEAM provide an exciting opportunity to fill these gaps. I will also describe my experience with building BEAM-based systems on seL4, integrating BEAM and seL4’s inter-process communication mechanisms to allow robust communication between Beam apps and native OS components.

Talk objective(s): Show how the high-availability programming and communication abstractions of the BEAM can be combined with the communication and programming abstractions of a formally verified microkernel to design and build highly secure and robust internet-connected embedded systems.

Target audience: Embedded systems software developers that are interested in designing and building systems with high levels of security and robustness.

04:00 PM - 05:00 PM

Lunch break

04:30 PM - 05:00 PM

Meet the Sponsors: EMQ. A deep dive in the Erlang backend DB extensions we added to scale.

Take a seat with Ivan Dyachkov and Thales Macedo Garitezi, software engineers with EMQ, for a talk on how EMQ scaled its clustering architecture to support 100M concurrent connections in EMQX 5.

Meet the Sponsors: Frame.io an Adobe company. Building creative software with Elixir.

Join Catherine Aronson and James Smith, in discussing how they built creative software with Elixir.

Meet the Sponsors: PepsiCo. Chat with PepsiCos’ eCommerce’s Data, Technology, and Experience Team

05:00 PM - 05:45 PM

Track 1

Title: Deep dive in Nx Backends

Speaker(s): Paulo Valente

Topic: Innovation

Tags: Advanced

Elixir’s Nx library implements its features through a configurable backend structure, in which inputs are dispatched to their respective implementations at runtime.

In this talk, we’re going to review Nx’s Backends and how they play with performance and automatic differentiation. For this, we’re going to study how Nx compiles and executes a given code sample and how using defn, Nx’s numerical function definitions, can enable Axon (a deep learning library) to work.

Talk objective(s): The main objective of this talk is to shed some light in one of the more technical and internal aspects of Elixir’s Nx. There are some articles here and there talking about this, but as part of the Nx team I hope to provide some more information about how the library works. This would also be one of the first talks on the subject.

Target audience: Although the talk is mainly about an Elixir library, I think all BEAM users which have an interest in machine learning would be interested in it, especially since it’s a direct product of the EEF Machine Learning Working Group. It can also be interesting for people which come from an ML background but don’t know much about the BEAM

Track 2

Title: One LiveView to Rule Them All: From Web to Mobile and Back Again

Speaker(s): Andrew Moore, Parker Rueve

Topic: Web/Cloud

Tags: Introductory

A year and a half ago a couple of apprentices and a supporting cast of mentors began working on a LiveView application. We recently launched that LiveView application into production. Let us tell you the tale of how we learned Elixir and the Phoenix Framework, and how we were able to turn that LiveView application into mobile apps that recently launched in the Google Play and Apple App Stores.

Talk objective(s): -To show how to turn a Phoenix application into something suitable for submission to the app stores. -Share our Apprenticeship experiences and learning paths up to this point. -Show how viable Elixir is as a great learning language.

Target audience: I think anyone that is interested in the conference would be interested in this talk. We were able to do some really cool things with a really small team of people over the last year, learn a lot of really cool stuff, and we would love to share those things with the world.

05:55 PM - 06:40 PM

Track 1

Title: Good behaviour: cultivating healthy Elixir teams and codebases

Speaker(s): Meryl Dakin

Topic: Growth

Tags: Introductory

This talk is about how we as Elixir developers and managers can use our tool most effectively. As an Elixir developer who’s worked at three companies at varying stages of using the language, I cover practices of adoption and maintainability I’ve seen work best. We’ll look at an organization adopting it for microservices, a legacy codebase rebuilt from Ruby, and a startup using Elixir for its greenfield application. We’ll delve into best practices around testing, context organization, macros, Ecto, and more. IC’s and managers will come away with tangible strategies to develop processes and organize their work so the codebase remains flexible and coherent for the future of the product.

Talk objective(s): To share best practices with organizations and individuals at any level of Elixir adoption to maintain a healthy codebase and aligned team.

Target audience: Elixir enthusiasts who are encouraging adoption on their team, developers on legacy codebases looking at how to standardize, managers working to onboard IC’s new to Elixir, anyone interested in best practices on production Elixir applications

Track 2

Title: When the Cloud’s Reign is Over

Speaker(s): Nicholas Adams

Topic: Web/Cloud

Tags: Introductory

Cloud Computing is great. It gives you practically instant scalability with no need for a large infrastructure team and guaranteed up times, plus the ability to try scaled-down versions of your projects at negligible costs before investing in major infrastructure.

So it came as a surprise to me to discover that, after a certain tipping point, cloud computing is actually horrendously cost ineffective! We’re not talking a few hundred dollars here, we’re talking up to double the IT budget you’d be paying to run the majority of your systems in house. That doesn’t even include any in-direct cost-savings such as reduced legal fees from simpler regulatory compliance! It turns out that GDPR and similar laws also become surprisingly simple when your customer’s data is physically located on servers you control.

Join me for this talk to hear a few examples and a couple of options to move from someone else’s computer to one of yours!

OBJECTIVES: To make people aware that the cloud is not the be all and end all of production systems.

To give people an idea of when they should start looking at migrating away from the cloud for cost benefits.

AUDIENCE: Anyone from dev-ops and sys-admin all the way up to CTO or CIO level

06:40 PM - 07:10 PM

Coffee Break

07:10 PM - 07:35 PM

Track 1

Title: Fast IP address matching in Elixir with Radix Trees and persistent_term

Speaker(s): Michael Lubas

Topic: Web/Cloud

Tags: Intermediate

When your web server receives a new login request, is it from a real user, or a rented cloud server? You have a list of thousands of IP prefixes, and need a way to compare each incoming conn’s remote_ip to that list.

This problem will be used to illustrate several features of Elixir/Erlang. The beginning of the talk will introduce the problem to the audience, and show why the default Elixir data structures are not suitable. Once the radix tree has been covered, we’ll move to the problem of thousands of processes needed to access the same data structure in a short period of time.

The talk will cover GenServers, ETS, and the constant pools optimization, and why these are the wrong choice for the problem. Finally, the complete solution will be shown, using persistent_term.

Talk objective(s)

  1. Introduce the problem of IP address matching
  2. Show why the radix tree is a good choice
  3. Compare GenServers, ETS, and persistent_term for this problem Target audience Elixir/Erlang programmers

Track 2

Title: On the way to achieve autonomous node communication in the Elixir ecosystem

Speaker(s): Hideki Takase, Shintaro Hosoai

Topic: Innovation

Tags: Advanced

Have you ever felt that finding communication nodes by specifying information such as IP addresses is complicated?

RTPS (Real-Time Publish Subscribe) is a communication protocol. The main advantage is that nodes can acquire autonomy in communication. Without setting up any broker, a node can automatically discover communication partners for publication/subscription only by specifying a topic. Note that the use of RTPS is restricted to the area under the NAT server. We are working on R&D about “Rclex,” a client library for ROS 2 platform. This library has directly integrated the feature of RTPS into Elixir.

This talk will consider how to bring the power of Rclex into Nerves devices. To find out the current status of Rclex, we will provide a way to realize this purpose. In addition, we will share our latest R&D activity to enable RTPS communication in Elixir/Nerves beyond the NAT server. Once achieved, we can apply RTPS to the wide-area distributed system.

Talk objective(s): The audience will learn about a new communication scheme that can even go beyond the NAT server, and the way to build wide-area distributed IoT systems with highly autonomous nodes.

Target audience: An alchemist who wants to construct wide-area distributed IoT systems.

07:45 PM - 08:10 PM

Track 1

Title: ActiveMemory the missing ORM for ETS and Mnesia

Speaker(s): Erin Boeger

Topic: Innovation

Tags: Intermediate

A package to help bring the power of in memory storage with ETS and Mnesia to your Elixir application.

ActiveMemory provides a simple interface and configuration which abstracts the ETS and Mnesia specifics and provides a common interface called a Store.

Use ETS and Mnesia to help boost your application performance, simplify configurations and secrets, help reduce database dependency, and more.

Talk objective(s): Introduce the ActiveMemory hex package and what problems it is trying to solve. Also help people better understand ETS, Mnesia, and how they can make our apps better.

Target audience: Anyone who has interest with in memory tables and or has had previous experience with ETS or Mnesia.

Track 2

Title: Tackling Technical Debt at Adobe: A Story which started at Frame.io

Speaker(s): Milton Mazzarri

Topic: Fighting technical debt

Tags: Intermediate

After the aquisition of Frame.io by Adobe, priorities shifted. From being a startup, we were catapulted to a world of enterprise software development, with the potential of a 10x increase in volumes. Our first priority was tackling technical debt so as to allow us to scale and integrate with their other products. In this talk, we will share some of the technical challenges we faced with a 6 year old Elixir code base and how we dealt with them. From internal code changes, improvements in stability, observability, the database layer, and of course, scalability. These initial improvements allowed us to replace some of the in-house applications with OSS and other Professional packages like Oban Pro+Web, and Broadway. In this talk, you will learn not only how to deal with technical debt, but also how to deal with management, getting them involved in the process and giving you the bandwidth you need to address the issues.

Talk objective(s): Show how the team behind Frame.io gained stability, observability and scalability after focusing on paying its technical debt in a six-year-old codebase. And how tackling issues directly in our often neglected RDBMS resulted in immediate benefits. Target audience: Elixir Developers, Database (PostgreSQL) analysts

08:20 PM - 09:15 PM

Understanding the Notes

  1. Notes attempt to be in sequential order.
  2. Anything worth calling out falls to the bottom of the section, it may not belong in the stream of consciousness.
  3. Using the block quote > to show notes taken during rewatching the VODs.
  4. I don’t want to modify the original notes much but this should allow me to somewhat annotate the previous sections.
  5. Allows us to also add new sections.

Notes

12:00 PM - 01:00 PM

Welcome + Keynote: We are stronger together

No real notes as this was during lunch. It looks like Erlang as the “parent” is trying to understand all of the ecosystem that depends on it because it’s easy for one change to break through portions of the ecosystem. This looks like a great thing for the ecosystem as a whole and they’re looking for ways to keep from reinventing the wheels. This sounds like a great thing.

01:05 PM - 01:20 PM

OTP update

I’m not used to updates like this but it was good to understand what’s coming in Erlang 26. I think the interactive shell changes will be big for the ecosystem at large.

01:20 PM - 01:50 PM

Coffee Break

Teller Challenge: Do you have what it takes to crack the Teller Bank app?

I felt uncomfortable joining the tables to do talks virtually. I wish I was more extroverted.

01:50 PM - 02:35 PM

  • [ ] Track 1 - 5 - Network Observability at LinkedIn
  • [x] Track 2 - 8 - Refactoring via the Language Server Protocol

I started watching track 1 and joined track 2 late. Track 1 was prerecorded which is a great idea but it was also more Erlang heavy which I didn’t want to focus on. Turns out track 2 was the same way. I may also change this but they don’t have the terms tracks or lanes where topics are considered tracks in the UI.

02:45 PM - 03:30 PM

  • [x] Track 1 - 13 - Accessible Time-Series data with TimescaleDB
  • [ ] Track 2 - 1 - Building blocks and how to use them: a MongooseIM case study

I spent the majority of my time working on writing this notebook. I had reviewed Dave’s slides as a more beginner mind and I’m definitely interested in timescale as an approach of aggregating time data. I have a feeling I could use this at some point, I’m just not sure when. It’ll be interesting to link to the slides.

The introduction to the library has a Livebook example that really brings it all together [https://hexdocs.pm/timescale/intro.html].
