i released this morning erlang-rocksdb 0.17 with support of rocksdb 5.11.3, some performance improvements in CRUD operations and batches and a faster build: https://hex.pm/packages/rocksdb … enjoy!

Released test_match - matching function, which allows you to use function as pattern, match not strictly and provides colored diff in tests

My objective is reaching a performance comparable to jason or poison without compromising the code understandability. Please do not use the 2.0.0 version in production.

There were some exciting additions to ExVenture last month, the biggest being how your character’s stats boost during level up. Check out the post for more changes. ExVenture is a text based multiplayer game (MUD).

I utilize the power of OTP to bring the weather station to the next level. Automatically read from all sensors, build data payload, and setup client structure for sending to server. @NervesProject #myelixirstatus #RaspberryPi

Raxx can be used to build web applications much like Plug. However that is where the similarities end.

Today I want to introduce you Annon, our free, open source API gateway: https://github.com/Nebo15/annon.api

It is well-documented, tested in production and it has a configuration UI, a command-line utility, and even authentication provider. It even generates a status page for your API’s!

ex_money 2.3.0 adds support for subscriptions including:

• creating a subscription
• creating a plan
• changing from one plan to another including applying credit for unused time on an old plan by either prorating the price or prorating the time of the first plan interval.
• calculating plan intervals

There’s an easy way to test sessions in Phoenix (and Plug!) Unfortunately, it’s a somewhat new feature in Plug and not widely known. Short post to demonstrate how it can be useful.

Part 2B of a long series about microservices. In this part, we finish preparing the data that we’re going to put in our services, so that we can launch them in the next post.

After last years successful bootcamp, we’re organising another Elixir Bootcamp in Amsterdam, for all of you wanting to learn Elixir.

Latest v1.0.4 release features Union Patterns, that let you compose many named patterns into a single one.

Using unions, you can emulate things like Algebraic data types

For some examples, see:

• Natural numbers.
• Maybe.
• Either.
• Result.
• Union on Struct.

This is a major upgrade of the Cloak encryption library for Ecto.

See the release notes, and try it out, especially if you’re already a Cloak user. Feedback is welcome.

In this episode we get an introduction to Phoenix Channels by using them to build a chat room in 8 minutes.

Here’s a first stab at modeling a content management system for Alchemist Camp!

The basic challenge is to have multiple types of content—articles, episodes and resource pages that can all be tagged and liked by users in a mostly unified way and yet have structural differences enforced by their schemas.

What are some lightweight ways to do dependency injection in Elixir that don’t require the ceremony overhead of a Behaviour? Join us as we explore four more ways to model our function interfaces for easy testability!
