Using Ecto 2 and hound, we can run multiple acceptance tests concurrently in elixir. Here’s how:

This is gossip communication library originally developed for the scalesmall experiment, but I decided to release it as a standalone library. Here is a long post about the internals and design of the library:

http://dbeck.github.io/Chatter-extracted-from-ScaleSmall/

The TL;DR is that it supports:

• to use the library one only need to read a few lines of code in the middle of the post
• securely encrypted and compressed communication
• a mixed broadcast model, utilizing UDP multicast and TCP together

I just released v0.3.4 of Credo, a Code Linter for Elixir that let’s you enforce your style guide while teaching you things about Elixir best practises.

You can read all about this bugfix release in the CHANGELOG.

Linked below is a demo application that pushes Exometer data through Phoenix channels to the UI. Each browser session creates 10 web socket connections to the server and receives new data every second. It in itself is not that special but there are some neat observations:

• The browser is the bottleneck when trying to chart large amounts of (real-time) data
• Sockets take very little memory - opened 500 sockets and memory increased by a couple of MB only
• Once all sockets disconnected, memory usage returns to normal; there is no leakage

I learn how to use GenEvent and use to trigger channel broadcasts.

I posted an update to my robotics with Elixir blog.

Quite a lot happened this month:

• A meetup on mixing Elm and Phoenix to build a robot dashboard - slides
• A Raspberry Pi encounter
• And an invitation to speak at Elixir Daze.

Toggl is a very useful tool I use everyday to track my work so I couldn’t resist creating a very basic tribute/clone using Phoenix, React and Redux to test out some of the new things I’m learning about OTP processes and taks.
