Any recommendations for an entry point into Elixir? I've been teaching myself Rust through resources like Rustlings and 100-exercises-to-learn-rust, and I've found that approach to be pleasantly accessible. I've yet to find something similar for Elixir, whether interactive or just well laid-out.
Elixir 1.17 released: set-theoretic types in patterns, durations, OTP 27

#102Super-excited for this release. I wish someone would put some resources into the Elixir IntelliJ plugin. I've tried, but I just can't enjoy using VSCode (vs IntelliJ based IDEs, Visual Studio, etc.)
Absolutely agree. I love Elixir but the editor integration has always been unfortunately second-class. The happy paths in VSCode work well enough with the ElixirLS, but there are a few flaws that are a quite a bummer. One major one is no rename / refactor functionality (seriously?!) and a more Phoenix-specific issue is trying to contend with auto-complete in templates, which is no fun. I like VSCode fine, but I'd def…
Use lexical instead of elixirls and most of your worries will be gone

A news aggregator (and premium news chatbot) that indexes and analyses around ~150.000 new articles a day ( http://im.fo ) I'm absolutely certain the real time processing would be unfeasible in any other technology in terms of complexity and the minimal compute resources it's running on. Modules like broadway, ash, oban, phoenix liveview ... make it not just a pleasure to work with but insanely performant. With over…
You know that Elixir is on the low end of performance right, so you take Go/Java/C# that are close to 10x faster.
performance has many dimensions. for example the cost/speed of spawning a process/thread and their intra process communication.

#104The last few years the Elixir ecosystem has started to become the simplest solution to so many use cases: - Web development with Phoenix and Liveview is immensely enjoyable and fast - AI with NX, Axon, Bumblebee - Audio and Video streaming and manipulation with Membrane - CQRS and Event Sourcing with Commanded - Embedded with Nerves to make your own devices - Mobile apps with Liveview Native ( in development ) - Queu…
Now the only thing left: figuring out how to deploy it.

it's pretty straightforward and simple with `mix release`

Yea I never bought this assertion from the TS team, saying “given the trade-offs at the time” is the same as saying “we’re already backed into a corner by previous decisions” - the decision(s) may have been intentional at each step but the design itself probably was not. Given the choice of sound or unsound, considering that the purpose of a type system is to give certain guarantees, a type system design must always…
Is the TypeScript team correct in explaining that soundness would exclude functions accepting subtypes as laid out there? If so, it seems like any type system that was meant to be able to type common JavaScript idioms would have to be unsound.
Yes and no - you can't have bi-variant argument types as shown here and be sound, but that does not mean you can't type those idioms. You just need the type system to be able to express a dependency between the name of the event handler and the type of the associated function. It is not exactly straightforward (this is a complex type system feature) though, I don't blame the TS devs for going for an escape hatch there.
(Edit: to be clear, allowing to refine function types in the way they do is part of the solution, the unsound part is that it is not checked afaik)

I remember trying to deploy it a couple years ago and it was fairly complicated. Granted, I was trying to deploy a multi-node mnesia cluster, which is probably what caused all my issues.
But for non-production single nodes I just created a Dockerfile and deployed it because the other options were too much hassle. Can't remember the details, but in my (in)experience, deploying was always the hard part with Elixir.
I will need to try it again, it's been a while and the ecosystem has improved dramatically in the meantime ... and it was already excellent before. Good stuff!

> Adding types is indeed the last piece to the puzzle to bring even more confidence in the code we ship.
This is the hard missing piece for me and why I'm looking curiously over to Gleam. Coming from a language with a very powerful and useful statical typesystem, I just can never go back to something like Erlang or Elixir in my life. :-(

The Elixir REPL is world-class, and I agree that it's a truly killer feature of the language. I miss it terribly when I write stuff in other languages (i.e. any time I'm coding, you know, for money). Having a good REPL just removes so much of the friction you normally have to contend with in programming. You can build up ideas piecewise and test things as you go, instead of having to make guesses and run the whole da…
Recently moved my python app over to Elixir, and currently gushing over Elixir every day. I'm a huge fan and have loved everything about it, except... Comping from a LISP, the Elixir REPL really is not world-class. It's a really far, distant second. It's nice, I enjoy it more than python's personally, and more than what I remember from irb back in the day -- but nothing beats the integration of structural editing and…
