ExVenture is a text-based multiplayer game server.

ExVenture got a lot of cool new features in the last month, distributed mode is slightly more stable, there is a web chat, and a Mudlet package!

Just blogged on possible pitfalls when dealing with accented strings (with examples in both Ruby and Elixir.)

Naïve approaches vs. voilá—it works.

On the 5th of Juni we’ll host a Getting started with Elixir Meetup here @grandcentrix in our cologne offices.

We’ll eat some pizza, have some drinks, learn about Elixir and hack something together! Everybody is welcome and no prior experience is required!

Bring your laptops!

This article comprises of things that you’ll encounter while working with Strings and Raw bytes explaining with real situational examples. I tried to design the images, to focus on what we are talking. Hope you like them.

A small gist

Kerosene 0.8.0 is released https://github.com/elixirdrops/kerosene

Hi everyone,

We (Annkissam) just published our deployment automation package, akd. Akd is inspired by ruby’s Capistrano. It allows Elixir developers to easily compose a series of automated deployment tasks, and integrate with tools like distilery and docker , which simplify building and releasing Elixir applications. For more information and a detailed walkthrough, check out this post.

Let’s continue our Bitcoin adventures by replacing our standard single-node Supervisor with a DynamicSupervisor and start recursively connecting to other peers in the Bitcoin peer-to-peer network.

Level is an alternative to real-time chat, optimized for deep focus. This is an early-stage project under active development.

Many functions take opts, and we’ve always wanted a unified interface for validating, defaulting, and documenting them. Optimal’s schema based approach allows for optimizations and auto-generated documentation.

Beware of the Software is a new screencast, mostly on distributed systems with Elixir.

The first episode is up and it’s on building a small gossip middleware with Elixir.

Phoenix 1.4 not yet released. But you might want to use Webpack already today. Can you do that? Sure.

This is part 2 of a series on Elixir Protocols. We start by using derive with the Protocol we defined last time, and then we look at the more complex usage of derive in the Poison.Encoder library.
