Pogo - distributed supervisor for Elixir

Pogo is a distributed supervisor built on top of Erlang process groups. It abstracts away the complexity process scheduling and supervision in distributed environment. https://szajbus.dev/elixir/2023/05/22/pogo-distributed-supervisor-for-elixir.html

Recompile your code from within IEx

I’ve seen people quit out of IEx and restart it to load new changes to their code.

No need for that! Here are some cool helpers for you 👇

  • recompile/0 will recompile your whole project
  • r/1 will reload and recompile a single module

ThinkingElixir 152: Rust and Elixir Play Great Together

Episode 152 of Thinking Elixir. Rust is a popular lower level language and the community has created a number of libraries to solve different problems. We talk with Jason Stiebs, a Phoenix Core Team member, about how Elixir and Rust can play well together. Jason wrote an article about how he leveraged an image processing library available in Rust by using the Elixir Rustler package. We talk about how Rustler works through NIFs, and we learn how easy using Rustler has become. It’s great to understand that we have a powerful escape hatch like Rustler for those times we need it. We also get Jason’s insights into the Phoenix project and talk about the importance of improving the developer experience when a LiveView crashes and more!


Tackling Performance Issues in Ecto Applications

Leveling up your Elixir codebase with types

Types in Elixir, while not mandatory, can greatly improve your code base and developer experience while simultaneously preventing the project from falling into the “legacy” space. https://medium.com/wttj-tech/leveling-up-your-elixir-codebase-with-types-795bd17d4d70



Experimenting with graph databases with Memgraph and Elixir

I had a conversation with Marko Budiselić, the CTO at Memgraph, during this year’s DORS/CLUC conference. We discussed graph databases in detail and explored their capabilities and applications. Since I had no prior experience with graph databases, I found the discussion fascinating. As an enthusiastic user of Elixir, I was especially curious about the possibility of integrating Elixir with Memgraph and using its features within the Elixir ecosystem.

The idea of this post is to experiment with Memgraph and see (1) if we can use it with Elixir at all, and (2) how it all works under the hood. As of the time of writing this I haven’t found any tutorials or guides on how to use it with Elixir, and we obviously need to fix that ASAP 😀.


Mind Games in Elixir: Crafting a Command Line Number Guessing Game

In this blog post, we’ll create a fun command line game using Elixir. By the end of this tutorial, you’ll have a good understanding of how to use Elixir to develop simple command line games. So, let’s dive in and start coding our own guessing game in Elixir!

Loading a structure.sql File on Prod Without Mix

Have you run mix ecto.dump and now rely on a structure.sql file to bootstrap a new DB? When you deploy a release to a production-like environment, you don’t have MIX and you can’t run mix ecto.load. See how we can still bootstrap a clean staging environment or deploy to a fresh prod DB! (Spoiler: We’ll steal code from ecto_sql!)

Taking Control of Map Sort Order in Elixir

OTP 26 was released and the Elixir 1.14.4 builds have been updated! Erlang OTP 26 changed how map keys are sorted, or not sorted actually. Check out this quick tip on how to customize IEx to always sort the map keys with your local development!


Get previous values in IEx

To access previous values in IEx (and save some typing) use the v/1 helper:

  • v() gets the last value
  • v(n) gets the nth expression
  • v(-n) gets the previous nth expression

Intro to Protocols

Elixir protocols provide a powerful mechanism for polymorphism and code reuse. In this episode, we’ll get an introduction on how to use them.


ThinkingElixir 151: Peeking inside the Livebook

Episode 151 of Thinking Elixir. Recently Livebook had its first launch week. We met with Jonatan Kłosko, the developer behind most of the exciting new features, to learn what some of these additions are, how they actually work and what’s coming with the new Teams feature. Jonatan shares some of his favorite unsung features and where the new apps ability may go in the future. Livebook is an important community project and it’s fun getting a deeper look inside!
