Due to talk at Code Mesh V on why Mainframes are still relevant (and cool)! Check out this preview article on Herb's journey of discovery.

The global outbreak of COVID-19 has impacted us all. We hope that you are safe and extend our thoughts and best wishes to everyone who is directly affected by the crisis.

Day 1: The Tyranny of the Rocket Equation

We experience the real world by reacting to events that have occurred, what if we modelled our Elixir applications in the same way? Event sourcing is an approach where application state changes are modelled as an immutable series of application-specific domain events over time. Changes made by end users of such applications are recorded as new events. Unlike in a traditional CRUD application, where updates and deletes are destructive operations, events are never deleted. OBJECTIVES Introduce the concept of event sourcing with a practical application in Elixir. Talk covers the how, why, and why not to apply an event-driven approach to building your Elixir applications and services. AUDIENCE Anyone interested in discovering how the simple concept of using domain events to capture state changes can bring tangible benefits to application development.

From startups to banking giants, Erlang and Elixir has been making a splash in fintech stacks for years. Finally, this year, we’ll dedicate an entire conference to the inspiring work done on the BEAM in fintech!

Elixir has a concept of protocols which provide polymorphism on data types and structures. In our example we pipe the result of generating a MapSet into the to_list/1 function on the Enum module. Enum is a module containing functions that work on data types implementing the Enumerable protocol; examples of these are lists, maps, and ranges.

When a list in Elixir contains tuples, where the first element is an atom and the second element is a value of any term, it is considered a keyword list. Keyword lists have a special visual representation, and the square brackets can be omitted if the keyword list is the last argument of a function or macro call, or is the last element in a tuple.

Code BEAM Lite 2019 was on 22 March in Bologna, Italy's food capital! In an encouraging environment, attendees got to grips with key Erlang and Elixir concepts, through eleven carefully selected talks. The conference was a great success, below we share the slides from all the talks.

ElixirConf EU conference is the European hub for the Elixir community, their 27 talks and are carefully picked each year. As a result, the themes of the conference are a good guide in finding out what is trending in 2019. Our Elixir expert has considered all the talks that will take place between 8–9 April, and found 6 main themes this year.
