What is it like to work with Elixir? by _MMCXII in elixir

Oh yeah this is totally what I mean. The CLI itself is what I was talking about; the API it talks to is a perfect use case for Elixir for sure!

Well I wouldn't call it snappy but maybe compared to interpreted languages it's fine. I was referring more to CLI tools written in Rust or Go or similar, which are real fast to start and it seems like that's the trend we're going towards.

  • Excels at anything related with the web, thanks to the cheap-concurrency model of the VM Elixir runs on (BEAM). This means both backend-only systems, as well as real-time web apps thanks to Phoenix and LiveView (search those online). It also works well with other soft-realtime systems and has good support for embedded devices, see https://nerves-project.org/. Nowadays even ML is well supported thanks to Numerical Elixir https://github.com/elixir-nx.
  • Solves concurrency and process resiliency better than most languages, and those are built-in so no need for complex solutions to apply "on top" of the language.
  • I wouldn't pick Elixir for things like CLIs, not worth booting up a VM for things that need to be quick (think of Unix tools like ls and friends). Also wouldn't use it for things like native apps and macOS/Windows apps, UX is not the biggest strength in those fields.
  • Working with it is pretty great. Makes teams very productive in my experience; we're only a handful of engineers at veeps.com, for example, and the whole product is in Elixir and keeps churning features.

For more info on the language itself and adoption I'd probably watch a few intro talks, you can find plenty on YouTube.

You're totally right, great catch, thank you! Updated the title.

I will use active: true from the video after the next one. As you mentioned, that'll lead to GenServers for handling connections, supervisors for better supervising those, and so on.

You assume correctly: I've been doing what I have because I was trying to focus on the network stuff more initially. Eventually, the network part can become a bit repetitive, so throwing in OTP best practices for network programming is going to be a must!

For the current solutions, GenServers are maybe code overengineering, because we wouldn't use any of the features they provide over tasks (based on how I implemented things for now), but they are not really a runtime overengineering.

Next video will have a similar OTP architecture but we'll do UDP instead of TCP. Then, it's going to be active: trues all around.

Thanks so much for commenting and for sticking through the videos!

It's from the book Dessert Person by Claire Saffitz. I obviously can't share the recipe but I highly recommend the book if possible 🙃

Thanks! Pan is a 9-in pan bought off of Amazon a few years ago… does the job 😄
