In the first part of a two-part series, we'll touch on some tools you can use for debugging in Elixir.

I run a couple of internal and public applications written in Phoenix on our infrastructure. While services like fly.io exist and are amazing, sometimes it’s both cheaper (and more secure) to run small internal applications on your own hardware. It’s certainly more fun. Thru the years I’ve developed my own process of deploying the application and this post will document the current procedure.

I should first clarify that I would never come out against the idea of writing tests for your code.

You sometimes feel the need to make all of your integers positive, without losing any information. That is, you want to map all of your integers from ‘signed’ integers (e.g., -1, 1, 3, -3) to ‘unsigned integers’ (e.g., 3,2,6,7). This could be useful if you have a fast function to compress integers that fails to … Continue reading Making all your integers positive with zigzag encoding

As I wrote last week, this summer I’m working on bringing the power of NoSQL to Ecto. This week I’d like to share with you what I learned about Ecto adapters alongside some tips on how to implement Ecto adapters for new databases. Maybe this will be your next week-end project? What does it take? Creating adapters for Ecto is really easy. The documentation is great (as in all core projects in Elixir), there are many helpful people, and the APIs you have to implement are straightforward and clear.

This article will explain the best ten frameworks for the Elixir programming language. The list includes Phoenix, Nerves, Sugar, etc.

Today on the show we are joined by Michal Muskala, who is currently a freelance software engineer and he is here to talk to us about his work on the Ecto and jason libraries. With Ecto we continue our journey into Elixir and Michal explain how he became involved in the project and the work he did on it. He explains a little of its inner workings, issues and what excited him about it initially. We then turn to jason, a widely popular library that Michal created for parsing JSON. Michal unpacks its particulars, differentiating for us between the driver and adapter and the lessons he learned working on them. The last bit of our conversation is spent talking about open source and Michal's commitment to its philosophy. We discuss making time to work on projects, buy in from employers and and why getting involved can be scary yet is so important! For all this and more, join us for this great episode!
