Kubernetes and the Erlang VM: orchestration on the large and the small « Plataformatec Blog
If you look at the features listed by Kubernetes (K8s) and compare it to languages that run on the Erlang VM, such as Erlang and Elixir, the impression is that they share many keywords, such as “self-healing”, “horizontal scaling”, “distribution”, etc. This sharing often leads to confusion. Do they provide distinct behaviors? Do they overlap? For instance, is there any purpose to Elixir’s fault to
What's new in Flow v0.14 « Plataformatec Blog
Flow v0.14 has been recently released with more fine grained control on data emission and tighter integration with GenStage. In this blog post we will start with a brief recap of Flow and go over the new changes.

What’s new in Elixir – Jun/18 « Plataformatec Blog
Erlang/OTP 21.0 was just released and work on the upcoming Elixir v1.7 release is ongoing. In this post, we highlight some of the features that have already landed in the Elixir master branch. Elixir will now provide hints of where a mistake may have happened when you forget a do or an end (commit). Erlang/OTP 21.0 introduces a new way to retrieve the stacktrace that is lexically scoped and no lon
Adopting Elixir: the book and beyond! « Plataformatec Blog
Adopting Elixir is a new book from PragProg, written by Ben Marx, José Valim and Bruce Tate, with the goal of exploring the Elixir adoption life-cycle from concept, to development and into production. After all, adopting a new technology is more than programming. Although a relatively young language, Elixir has plenty of learning resources available. You can learn about functional programming, con
Elixir, processes and this thing called OTP « Plataformatec Blog
One of the notable features provided by the Elixir language is the way it handles concurrency, how this is beneficial on a daily basis and adds value to the final software. And one of the things that comes up when learning about concurrency in Elixir is an acronym we hear a lot, called OTP. The acronym stands for Open Telecom Platform, but it isn’t used just for telecom nowadays. In the book Desig
Book Release: Learn Functional Programming with Elixir « Plataformatec Blog
Last week, The Pragmatic Bookshelf started the sales of Learn Functional Programming with Elixir written by me, now in beta. After one year of hard work, we are finally publishing the beta version of the book. In this blog post, I’ll tell you about the motivation for writing a book, its contents and its future. Why Writing a Book? Last year, we were, company-wise, looking for different ways to con
Small data with Elixir « Plataformatec Blog
This is the first article in a series of articles about “small data” (in contrast to “big data”) in Elixir. We will start by defining what is “small data”, why it matters and then briefly describe the Flow tool and what to expect in the next articles of the series. How small is small? We define small data as data that can be processed by a single machine in a desirable time interval. Such work may

Replacing GenEvent by a Supervisor + GenServer « Plataformatec Blog
The downsides of GenEvent have been extensively documented. For those reasons, the Elixir team has a long term plan of deprecating GenEvent. Meanwhile, we are introducing tools, such as Registry (upcoming on Elixir v1.4) and GenStage, which better address domains developers would consider using GenEvent for. However, there is a very minimal replacement for GenEvent which can be achieved today in E
Dynamic forms with Phoenix « Plataformatec Blog
Today we will learn how to build forms in Phoenix that use our schema information to dynamically show the proper input fields with validations, errors and so on. We aim to support the following API in our templates: <%= input f, :name %> <%= input f, :address %> <%= input f, :date_of_birth %> <%= input f, :number_of_children %> <%= input f, :notifications_enabled %> Each generated input will have
Understanding deps and applications in your Mixfile « Plataformatec Blog
Note: Elixir v1.4 has been released and improves on many points touched by this article. From v1.4, Elixir will automatically infer the list of applications based on your dependencies. For more information, read the official announcement. In my journey as a curious Elixir developer, I’ve come across this seemingly simple question a few times: which applications from third-party libraries do I need
Deploying Elixir applications with Edeliver « Plataformatec Blog
We’ve been talking about deploy and releases with Elixir lately, like how to run migrations on top of a release or how to deal with environment variables. Now it’s time to discover another tool that can help us release our Elixir application. After practicing deploy and tracing through nodes with Exrm, we got more comfortable knowing that there is a tool we can count on for managing production rel
