Or in cases when our system becomes unresponsive despite the fact that all processes are up and running. That is where the system supervisor, like systemd, comes to play to help operations to keep the application up and running while being able to reliably observe the state of application. OBJECTIVE: Present the community that the supervisor approach is not distinctive to the OTP and that it is very handy solution to publish and manage BEAM applications within the existing systems without using additional tooling like k8s or Nomad. How to run applications in constrained and safe environments without usage of Docker/Podman while making it easy to run and manage on host OSes. AUDIENCE: Intermediate/advanced developers who want to manage their own applications and DevOps that are managing BEAM applications. • Timecodes 00:00 - 04:31 - Intro 04:32 - 05:12 - Similarities Between System init and Erlang init 05:13 - 08:50 - "Top level" Process Management" 08:51 - 13:18 - Notifications and watchdog 13:19 - 18:04 - Centralised Log Management 18:05 - 22:02 - Lazy Startup Socket Activation 22:03 - 31:34 - Demo Time 31:35 - 37:05 - QnA • Follow us on social: Website: https://codesync.global/conferences/code-beam-v-america-2021/ Twitter: https://twitter.com/CodeBEAMio • Looking for a unique learning experience?

Also learn about some of the phenomenal community tooling that we have available to us on the BEAM and how to setup PromEx to leverage all that telemetry goodness. OBJECTIVE The goal of this presentation is to give some background on the importance of application and system observability along with some best practices/anti-patterns. Next, we'll dive into some ecosystem observability tools available on the BEAM. Lastly we'll take PromEx for a test drive and see how easy it is to instrument our applications and extract metrics from all our telemetry supported libraries. AUDIENCE Anyone running production systems in Elixir who wants to step up the observability of their applications/systems. • Timecodes 00:00 - 02:11 - Intro 02:12 - 05:32 - Observability 05:33 - 06:43 - Why do you need monitoring? 06:44 - 08:46 - What are metrics? 08:47 - 10:29 - What should you monitor? 10:30 - 11:40 - How does monitoring impact the business? 11:41 - 12:40 - How does monitoring the engineers? 12:41 - 12:54 - Monitoring best practises 12:55 - 16:05 - Monitoring anti-patterns 16:06 - 18:32 - Push style metrics and influx DB 18:33 - 23:05 - BEAM Telemetry 23:06 - 28:41 - What is PROMEX? 28:42 - 29:47 - Project status 29:48 - 38:18 - Case study 38:19 - 42:49 - QnA • Follow us on social: Website: https://codesync.global/conferences/code-beam-v-america-2021/ Twitter: https://twitter.com/CodeBEAMio • Looking for a unique learning experience?

It's the foundation for Supervision trees, Agents and Tasks in Elixir, and GenServers. A new kid on the Actor Model block has arrived. With version 3, Ruby has implemented their own version of the Actor Model. We'll explore what it learned from the BEAM, and where it needs to grow if it wants to let developers build world class, concurrent applications with it. • Timecodes 00:00 - 04:18 - Intro 04:19 - 11:15 - Ruby, Rails, SonicPI and other projects 11:16 - 12:46 - My Elixir Status 12:46 - 16:10 - My Ruby Status 16:11 - 32:24 - 3 Lessons that Ruby can learn form the BEAM 32:25 - 38:45 - QnA • Follow us on social: Website: https://codesync.global/conferences/code-beam-v-america-2021/ Twitter: https://twitter.com/CodeBEAMio • Looking for a unique learning experience?

How can we measure that risk? What could we do to avoid the risk? How can we communicate the risk to people who depend on our tech team? And once we already have escalated risk, how do we reduce it? • Follow us on social: Website: https://codesync.global/conferences/code-beam-v-america-2021/ Twitter: https://twitter.com/CodeBEAMio • Looking for a unique learning experience?

If time allows, we will take the opportunity to hear Robert's thoughts on best practices for BEAM language designers. • Follow us on social: Website: https://codesync.global/conferences/code-beam-v-america-2021/ Twitter: https://twitter.com/CodeBEAMio • Looking for a unique learning experience?

This video was recorded at virtual Code BEAM V America conference, which took place on 10-12th March 2021 - https://codesync.global/conferences/code-beam-v-america-2021/ Fireside chat on Property Based Testing | John Hughes & Fred Hebert - Co-designer of Haskell and Quickcheck & author of Learn You Some Erlang, Erlang in Anger ABSTRACT Property-Based Testing is one of the most powerful testing methods out there, and the Erlang ecosystem has some of the best frameworks available across all languages. Property-based testing has the potential to drastically increase the quality of software we ship by testing for issues we couldn’t even imagine. Despite great tooling and promises, adoption is still somewhat limited. Simple examples are easy to write, but more complex ones can often feel like black magic. In this Q&A session, Fred Hebert invites John Hughes, one of the inventors of Quickcheck, to discuss adoption strategies, how to gauge the accuracy and effectiveness of property tests, potential ideas for the future, and any questions the people in the audience might have. • Follow us on social: Website: https://codesync.global/conferences/code-beam-v-america-2021/ Twitter: https://twitter.com/CodeBEAMio • Looking for a unique learning experience?

Fireside chat on Live View | Bruce Tate and Sophie DeBenedetto - Founder of Grox.io and Senior Engineer at GitHub ABSTRACT Bruce Tate and Sophie DeBenedetto, co-authors of Pragmatic Bookshelf's LiveView book, discuss what's so great about LiveView and how it will change web development forever. LiveView will change the way you develop single-page apps. By allowing you to focus your brain power purely on the server, and use the power of Elixir and Phoenix to support fault-tolerant single-page flows, you and your team will be more productive than ever before. Our host, Sophie, will pose some questions for our guest, Bruce, that dig into what LiveView is and how it differs drastically from traditional SPA development frameworks, how you can leverage LiveView to solve almost any problem a typical SPA needs to address, what this means for the future of web development and where LiveView is going next. Bruce will also have a chance to ask Sophie some questions. • Follow us on social: Website: https://codesync.global/conferences/code-beam-v-america-2021/ Twitter: https://twitter.com/CodeBEAMio • Looking for a unique learning experience?
