Elixir Programming Training for Beginners

A 3-days introductory course teaching the basics of the Elixir language.

Elixir was Stack Overflow’s most loved, most in-demand and best paid programming language in 2019. Elixir has many real-world uses that are attracting those in the know to add the language to their skill set. This three-day online training is the ideal way to learn the key concepts that will set you on your Elixir programming journey. Along with learning the key concepts of the language, you will discover the essential role of concurrency for BEAM. After completing this course you will be able to write parallel and concurrent Elixir applications that will scale using OTP Behaviours.

Building Android applications on Erlang intelligence

How do we utilize the power of Erlang in Android applications? We'll review the virtual machine that runs Erlang modules and enables communication with Android. During the talk, a simple Erlang game logic will be presented focusing on the aspects of integration, into a non-standard Erlang runtime system. CoffeeBeam Android VM is taken as an example to show the restrictions and optimisation considerations when planning information flow between the phone application and the underlying BEAM logic.


Show the possibility of running Erlang logic on Android and demonstrate what architectural differences need to be considered when compared to a PC.


Developers who are familiar with the basic concepts of at least one language on the BEAM.
