Elixir is the “new kid on the block” in Findhotel’s tech stack. I explain why we decided to use Elixir at FindHotel and how we approached its adoption.

I just wrote about my latest challenge https://medium.com/elixir-bytes/logic-programming-the-infamous-rete-algorithm-in-elixir-b2fb4de85e5e?sk=7bb7ada651b422992604dba7a667960e

Should it be a Multi Page App or a Single Page App?

Multi Page Apps are relatively simple, but you’re limited in what you can achieve.

Single Page Apps allow you to build a much richer UX, but you pay for it in terms of increased complexity and lower productivity.

It would be nice if there was an option that allowed you to build a rich UX, without all the complexity associated with Single Page Apps, right?

Well, that’s exactly what Phoenix LiveView offers.

In this episode of ElixirMix, we catch up with Eric Oestrich about his project Grapevine and his live coding online. Grapevine is open source and a great resource for people to look at. We cover the different OTP concepts employed, how it is architected, deployed, what people can learn from it, and much more!

Enhancements

• Show Parameter Info (⌘+P/Ctrl+P)

Bug Fixes

• Fix must specify non-empty ‘commandLine’ parameter

• GeneralCommandLine‘s escaping for Windows can’t handle the parentheses in a way that both works for the Windows shell and Elixir running the code the shell hands off. Removing the parentheses leaves runnable code even if it is no longer formatted.

  Fixes “Unknown Version” naming for Elixir SDKs and the “Probably SDK installed in … is corrupt” dialog from appearing.

Installation Instructions

With the new Interceptor v0.5.3 version, you can now intercept all your module functions with a single configuration entry using wildcards: intercept “Foo.*/*”, on_success: “Callbacks.happy/3”.

This should significantly simplify your interception configurations 🔧!

Blog Post

So I’ve been working on the second part of my dive into Ecto multi-tenancy using Dynamic Repos. It’s up now :)

I’ve spent recent years coding with Node.js. At some point, I realised there are so many other technologies to discover. I considered several options reviewing blogs, forums and surveys. I knew that I needed a language that would correspond to my skills and experience. I decided to explore the world of functional programming. It was like a promise of better performance and productivity. I then asked myself - “Why not try Elixir”?

Let me tell you my story based on true events.
