In the last episode of my ‘Real World Phoenix’ series we implemented user authentication. Now let’s see how we can implement user authorization by implementing different user roles into our system.

In this episode of ElixirMix, we talk with Adolfo Neto about Elixir Brasil 2019 and his perspective on the Elixir community. The panel discusses the Elixir code formatter, the steps we run in our CI systems, how to teach functional programming to OOP people and much more!

In which I embark to find bugs in my statistex library with property based testing expecting to find nothing because of loose conditions and existing tests… only to find 2 bugs.

Finding Bugs with Property Based Testing in a Statistics Calculation

The “How”s, “What”s, and “Why”s of Elixir Telemetry

It’s commonly quoted that ‘What gets measured gets managed,’ but how do you do that? Elixir’s Telemetry library enables you to stop worrying about how to capture your system’s data and more time thinking about what data to capture.

Phoenix LiveView pushState support - Change the URL without refreshing the page

It’s now possible to try the LiveView pushState support, to change the URL without refreshing the page!

This is part one of a new Elixir Testing series.

In this episode we’ll use the built-in library ExUnit to TDD our way through a common interview problem.

Track events in Mixpanel with useful context like referrer, user agent information, and UTM properties, and keep user profiles up to date on every request.

BetterParams is a simple Elixir Plug that lets you pattern match on Request params in controllers using Atom keys instead of String ones.

# web/controllers/some_controller.ex

def show(conn, %{id: id}) do
  # do something
end

Yep, that’s it. I wrote it because of my OCD. 😛

In this tutorial, I’ll show you how I implemented passwordless authentication with Phoenix for Proseful, the beautifully simple blogging platform that I recently launched.

I’ve been writing Erlang full-time for a couple months now, and there are some things from Elixir that I miss, and some others that I was expecting to miss that oddly enough, I’m not missing!

In this episode of Elixir Alchemy, we’ll discover the power of Phoenix LiveView by building a Go board without writing JavaScript or having to worry about browser state.

I wrote an article about #dialyzer for #erlang and #elixir. Check it out!

In this blog post we take a look at different data structures to implement a 9x9 board comparing their performance. This includes maps, tuples, lists, ETS and more. Also taking a look at why erlangs array is slower than using tuples straight up (although it maps to tuples itself) or why the map performance is different based on how many entries are in the map. Read on to find out.

In this episode of ElixirMix, we talk with Griffin Byatt about his library sobelow that performs static security analysis of your Phoenix applications. We discuss using the tool, common vulnerability patterns, upstream security fixes, thinking like a hacker, areas that need focus, resources for gaining security skills and much more!
