Easy, Concurrent Temp Dirs with ExUnit ✅

Sometimes we need a temp directory in tests.

Our first inclination might be to reach for System.tmp_dir!/0. And that works, but ExUnit has a really nice helper just for us.

Check it out!

Phoenix framework constantly ranks as the most loved web framework in the world in Stack Overflow annual survey.

My ambition with this article is to explain why it became the top pick in web development, as well as why developers and decision-makers who are still considering using this technology should try it out.

1BRC again. With some optimizations, I am able to process 1bn lines (using 10k different cities) on a 16 vcpu cloud machine in ~40 seconds using pure Elixir w/o dependencies (288 LoC)! As a comparison, on the same machine, a solution using Explorer.DataFrame’s would give me a runtime of ~20 seconds. Not too bad for pure Elixir!

Hello, I’ve been working on something for about a year and a half. I was fed up with Jira and other software in that category so I made my own with LiveView/Elixir. There is a free mode for one hour, but it can be restarted as much as you want.

Give it a look and let me know what you think! I made a coupon code in case anyone is interested past the free trial: ELIXIRSTATUS2024 It gives -25% for the first 3 months.

Sound effects are frequently used in games and media to make the experience more believable, and tangible. Sound effects also communicate information and can make an experience much more immersive. Phoenix LiveView is already highly responsive and dramatically simplifies the developer experience of creating real-time web applications. What would it be like to add sound effects to a LiveView page? This post and demo project covers how to do it and why it’s worth considering for your application. LiveView was already awesome, now let’s make it really sing!

After getting burned out by the React.js ecosystem, I tried multiple languages and frameworks, but ultimately, I decided to stick with Elixir and Phoenix.

Episode 185 of Thinking Elixir. Dive into the world of structured LLM prompting with our latest guest who shares insights on their innovative project, InstructorEx. We’ll explore how this tool is pushing the boundaries of large language models to return structured data, particularly JSON, and the benefits it offers when integrated into existing systems. The conversation takes a deep dive into the challenges and solutions of forcing LLMs to output data in desirable formats using Elixir technology, like Ecto schemas, and what it means to treat an LLM like a digital human, even applying it to tasks like spam detection in emails. Discover the intriguing concept of using a local database as a cache for LLM results. If you’re curious about the intersection of structured data, Python experience transition to Elixir, and the future of LLM integration, this is an episode not to miss. Tune in for these engaging topics and more!

I’m not a fan of writing {:ok, socket}/{:noreply, socket} in all of my LiveViews. Can’t pipe into them!

So, I typically introduce ok/noreply helpers in every single LiveView.

But my colleague had the brilliant idea to introduce them to the web module!

Check it out 🤩👇

This week José Valim announced that Elixir’s long-awaited gradual typing system is finally coming to fruition. But if dynamic typing was the reason you’re avoiding Elixir, I’d argue that your fears are overblown anyway.

Learn why Elixir’s lack of static types isn’t as big a problem as you might think:
