Yet somehow, the underlying fundamentals have remained largely unchanged for the past 30 years. The rapidly advancing cyber-attack environment combined with the use of networked computers in critical infrastructure, are causing a reckoning with the way computers, and all software is built. Strong isolation, from the top to the bottom of the stack is foundational. Erlang and the BEAM, as with so many other things, was way ahead of its time and pointed this direction many years ago. We are going to look at some of those lessons and show how they can used as a first-principle to design a fast, robust, and secure that is positioned for the next 30 years of computing. Strong Isolation is an inevitable shift that will reverberate through the industry. Understanding it now is essential to navigating the next round of scaled out software and computer deployments. • Follow us on social: Twitter: https://twitter.com/CodeBEAMio LinkedIn: https://www.linkedin.com/company/27159258 • Looking for a unique learning experience?

This is an example of a Survivor Bias which is a logical error in our understanding of the world, the assumption that success tells us the whole story about the process. Real world examples help us see how prone we are to it. During this presentation I want to talk about it with respect to testing, observability and monitoring. We will learn the techniques on dealing with it to make tools that are more reliable and exhibit our internal biases to lower extent. OBJECTIVES: Bring the phenomenon of survivor bias closer to the audience. Help realise how it can impact our judgement and what we can do about it.

In this story we’ll meet a cast of characters including Phoenix, Broadway, Oban, as well as Lambda, NodeJS, Ruby on Rails. Some worked well. Some were confusing. Some were both. Some I would use again. OBJECTIVE: The big takeaway that I would like people to take away is that Elixir and other BEAM languages provide a solid basis for resilient, critical infrastructure, perhaps more so than tools which might have better traction in enterprise companies. AUDIENCE: Software engineers, engineering managers, software architects. This would be better suited for intermediate to advanced practitioners. • Timecodes 00:00 - 04:34 - Intro 04:35 - 07:00 - Chapter 1. Tools 07:01 - 09:19 - Functions.

The BEAM ecosystem has powerful tools for observability and monitoring, from built-in SASL alarm handlers to telemetry and APM integration. We’ll learn about the tools at our disposal in OTP as well as some common libraries and services to make observability and monitoring easy. Additionally, we’ll discuss some tales of how observability and monitoring have lead to great success and great failure. OBJECTIVES: Attendees will learn key approaches for getting the most of observability and monitoring on the BEAM. We’ll cover key performance metrics how to correlate and interpret them. Additionally, attendees will learn about a few tools available in the BEAM ecosystem for observability and monitoring. AUDIENCE: This talk is useful for any engineers responsible for keeping their production systems running and reliable. • Timecodes 00:00 - 00:54 - Intro 00:55 - 04:06 - Why Observability & Monitoring? 04:05 - 05:28 - Fable 05:29 - 06:59 - How do We Optimize The Number of Pool Connections? 06:00 - 08:12 - How to Find # of Pool Connections? 08:13 - 13:01 - How Do We Tune That? 13:02 - 16:08 - Hertz 16:10 - 24:02 - Foible 24:03 - 25:10 - In Conclusion • Follow us on social: Twitter: https://twitter.com/CodeBEAMio LinkedIn: https://www.linkedin.com/company/27159258 • Looking for a unique learning experience?

This video was recorded at Code BEAM America 2021 - https://codesync.global/conferences/code-beam-sf-2021/ MQTT for Home Building Automation Hardware Interfacing | Omer Kilic - Embedded Systems Engineer at Ordinatra Minima ABSTRACT The countless interpretations of the term Internet of Things erased the boundaries of software / firmware / middleware / hardware and anyone embarking on an IoT project now has to understand the full stack. This is great engineering fun but harsh realities of project delivery, timelines and costs require creative thinking on how the “plumbing” of an IoT deployment should work. This brief talk will introduce the ubiquitous Zigbee wireless protocol and the ecosystem surrounding it, with a quick demo of zigbee2mqtt and some hardware in action. • Timecodes 00:00 - 01:29 - Agenda 01:30 - 07:07 - All about Zigbee2MQTT 07:08 - 07:30 - Device Support 07:31 - 08:37 - Deployment 08:38 - 15:15 - Demo Setup 15:16 - 17:02 - Interference Woes 17:03 - 17:50 - Further Reading 17:51 - 22:20 - QnA • Follow us on social: Twitter: https://twitter.com/CodeBEAMio LinkedIn: https://www.linkedin.com/company/27159258 • Looking for a unique learning experience?
