Smooth Token Emission for Elixium

We’ve recently implemented smooth token emission for the Elixium Network, which means that block rewards for miners will be more evenly distributed and will scale down without massive downward spikes. The algorithm for smooth emission is also weighted to distribute more tokens early on in order to incentivize early adopters.

Unit testing functions that interact with other processes

In part 1 of this series I went over a couple rules that I follow when writing unit tests. Now I’m going to dig in to some of the specifics of how to unit test certain types of behavior that can be a little tricky to do properly. In part 1 I said that unit tests test all functionality within a single process. But then how can we unit test something that talks to another process?

CyberSource Payment System — The implementation guide using Elixir

Phoenix 1.4 Chat Server: Part 2

In this episode we generate the needed contexts, schemas, migrations, controllers, views, and templates for users, their credentials and chat rooms. We also create relations between users and their credentials and set up password hashing.

Unlike Part 1, nothing in this one was specific to Phoenix 1.4.

Jupyter Notebooks with Elixir and RDF

I just published a post today ‘Jupyter Notebooks with Elixir and RDF: Using IElixir in JupyterLab with the SPARQL.Client package’.

The post very briefly touches on the role of Jupyter Notebooks as computational notebooks which integrate live code, text, math and media.

It then shows how we can use the IElixir kernel to run a Jupyter Notebook with Elixir as our language of choice. Using the TestQuery module developed in an earlier post it shows how this can be used within a Juyter Notebook context to run SPARQL queries using the SPARQL.Client package directly from the notebook and to process the SPARQL query result sets.

𝕰𝖝𝖛𝖆𝖑𝖎𝖇𝖚𝖗 → Smart Validation In Elixir

Exvalibur is the generator for blazingly fast validators of maps based on sets of predefined rules.

Under the hood, it generates a module with many different clauses of the same valid?/1 function with direct hardcoded pattern matches and guards on the input.

Here is the blog post shedding a light on what goodness it provides and h)ow is it implemented →

NEW YORK, NY, October 31, 2018 — Today POA Network, Compound, and ConsenSys announce that they have formed a collaboration on an open-source Ethereum client called Mana written in Elixir.

The Dangers of Genservers

When I first started Elixir, I had a hard time figuring out if I should wrap all my code in a GenServer, or what the boundaries were while utilizing them.

In my new blog post I go over the pitfalls of using GenServers and potential strategies to avoid them.

Don't Repeat Your Domain Knowledge

I often feel that we are not using modules/classes/functions to extract domain knowledge often enough.

In this post, I discussed why we need DRY and when is the best time to do it:


  • We need DRY because we need to eliminate the duplication of knowledge.
  • Both “abstract later” and “abstract early” are bad.
  • What we really should do is to look out for our domain knowledge and persist them as part of our code.
