Tarearbol library that eases the dealing with tasks got a massive update.

• use Tarearbol.Pool to create worker pools with no boilerplate
• call/3, cast/2, and terminate/2 callbacks to handle messages directly sent to the worker process
• __init_handler__/1 (or init: mfa() parameter in a call to use) to customize initialization process.

Hi everyone,

I’ve managed to get 3rd release of my book out!

I guesstimate it to be about 75% finished and with 15 chapters, it’s 200+ pages long.

The book is reaching the stage where additional contents will be “add-ons” to what we already have there like for example indicators. I would love to get some feedback - are you happy about the contents? what else would you be keen to see inside this book?

Also, I decided that this book will be “sold” in the “pay what you want” form forever <3 (although some $$$ would be totally cool with me :D)

Feel free to reach out if you found any issue / drop a comment / say hi ;)

Happy Tuesday!

Finally, we can easily do Elixir releases with runtime configuration.

In episode 38 of Thinking Elixir, Saša Jurić shares how the team at Very Big Things is building maintainable Elixir code. This ranges from the development processes to code design and organization. He takes some “radical” positions and challenges conventions on a mission to find what actually works well. We talk about his library Boundary and how it helps enforce API designs. He talks about the “Junk Drawer Pattern” and how code analysis helps identify lines of separation for refactoring. A thought provoking and fun discussion!

I recently got hold of this book Building Git, written by James Coglan. It’s a pretty thick book covering, as the title says, building Git version control system using Ruby programming language. I thought it would be a fun exercise to implement Git using Elixir as I read the book. This article is the first introductory one in a series of articles focusing on my journey implementing Git in Elixir programming language.

A deep-dive into how Wallaby uses the “sandbox” in Phoenix/Ecto, and how we can use it to keep browser tests asychronous even when using resources that must be explicitly shared between processes (such as Mox definitions).

This article comprises a simple example with an anonymous function that explains the data immutability in Elixir Programming.

The concept of data immutability is that the data once it is created in a memory location cannot be altered. Immutability must be preserved

Here you can find resources for getting started with Elixir. It’s what I am following and it could be helpful for programmers that want to learn Elixir.

To promote Tarearbol.DynamicManager I created the 😻-language (which is a brainfuck dialect.)

Code outputting “Meow” to the console looks like this:

A few months ago, I sped up one of our test suites from about 6 minutes to around 20 seconds. I describe my debugging journey and how I found out that fallback protocols could be causing slower tests when running with code coverage and defining protocol implementations can improve the speed.

Today I am happy to announce https://github.com/gordalina/hush - the simplest way to inject secrets into your app configuration.

Hush was purpose built to solve a common use case for projects that require secrets and want to inject them in a secure way without having to depend on secret files or hardcoded configuration.

The version 0.5.1 includes package updates. Check it out: https://hex.pm/packages/event_socket_outbound

In episode 37 of Thinking Elixir, after covering the news, we share a live recording of the show from the Lambda Days conference. It was a lot of fun! We covered topics like learning and teaching Elixir, functional programming, strengths of Elixir over Erlang, the developer tooling, why Elixir is awesome even when not building distributed systems, and much more!

If you ever wondered, how to reference existing enum functions in Absinth enum macros, wonder no more.

Here’s a quick tip on how you can add more customized page, using own Phoenix LiveComponent to your LiveDashboard. https://www.amberbit.com/blog/2021/3/1/adding-truly-custom-page-to-phoenix-live-dashboard/

To build a supervised, fault-tolerant and robust system, to run many processes holding nearly the same state, it saves a lot of boilerplate, claiming to implement perform/2 callback only (and maybe two optional callbacks call/3 and terminate/2.)
