At Savi Solutions, our video surveillance platform needs to be able to process billions of records per day for customers including Burger King, Little Caesars, 5 Guys, and more. As a result, we need a low latency, high performance, and linear scalable database, so we chose Cassandra. However, as our Cassandra cluster began to exhibit performance issues, degrade, and grow in cost, it was evident th...

In Simon Brown's talk at AOTB 2019 he explores the visual communication of software architecture based upon a decade of Simon’s experiences working with software development teams large and small across the globe. He looks at what is commonplace today, the importance of creating a shared vocabulary, diagram notation, and the value of creating a lightweight model to describe your software system...

In a real-world situation, the course of action that brings the most business value isn’t always the most elegant solution—I’m sure I’m not the only one who’s ever remoted into a production application and copy-pasted Elixir code, or had to interface with some legacy portion of a business that’s still using emailed excel documents to operate an enterprise-scale operation! There will always be the...

Frank Hunleth gives an introduction to embedded systems and IoT, show why the Elixir programming language is interesting for embedded, and then show how to get started with Nerves Livebook.

Whether you're developing a small web site or a large-scale distributed system, Erlang and Elixir are great tools for building server-side systems. Both languages can help you start quickly and deal with highly complex problems at a large scale. This talk aims to explain what makes Erlang and Elixir suitable for such tasks. We'll look past the syntax and the ecosystem, focusing instead on the conc...

https://go.dok.community/slack There are bad things that databases do to Kubernetes and there are bad things that Kubernetes does to databases. On top of that, deploying two highly opinionated distributed systems like Cassandra and Kubernetes, there is inevitable conflict. Is the effort even worth the trouble? This work is getting done and in this talk, you will learn about the rapid changes in b...

Follow me on Twitter to get more tips and tutorials! https://twitter.com/AlchemistCamp​ This continues from where the last screencast left off and we started from a new Elixir Mix project, added Ecto and configured it to connect to a database. This time, we use Ecto to create database migrations and then use those migrations to create DB tables for our project. For more lessons, sign up at https...

This episode creates a new mix project (without Phoenix) adds Ecto to it, configures everything and creates a database. The list of all episodes can be found at https://alchemist.camp/episodes.
