I finished working thru “Programming Elixir 1.3”. It was theoretically interesting, but I’m left wondering how to use it to accomplish real world tasks. I’ve been a developer for a long time. My background is in imperative procedural languages, focusing on back end apps that are highly DB, and mode…

[image] bbense: With the BEAM that scaling comes almost for free, you can just throw hardware at your code and it will work. Not entirely free, you still have to make enough processes and split up your calculations enough that concurrent work can be done. That is pretty trivially easy to emu…

Insert semi made up quote about “Every sufficiently concurrent program includes a buggy half-implemented version of the BEAM”.

My concern was not the theory or benefits of Elixir. My question was about where the rubber meets the road. In a simple real world example, you have a task to query and join a half dozen different data sources, perform a bunch of arbitrary logic and output something. In Elixir, would that simply be…

[image] Justin: you have a task to query and join a half dozen different data sources, perform a bunch of arbitrary logic and output something. In Elixir, would that simply be a set that you pipe thru a ton of functions? That is the essence of functional programming in the rough, yes. You hav…

[image] Justin: In Elixir, would that simply be a set that you pipe thru a ton of functions? Pretty much - for example: defmodule Summary do defstruct order_id: 0, items: [], customer_name: "", date: Date.utc_today() defp cons_description(order_id), do: fn (%Item{orde…

[image] Justin: My concern was not the theory or benefits of Elixir. My question was about where the rubber meets the road. I wouldn’t buy anymore books. You are a kindred spirit as practical is how I really learn and 90% of the books on programming SUCK for that. I found Google better for f…

Google is great when you just want to get something done. Books have their use too. They can help to answer questions you didn’t even know to ask.

[image] Justin: My question was about where the rubber meets the road. Apologies for necroing to the mods but this discussion is interesting. :023: The way I educated myself with Elixir professionally pretty quickly was to try and replicate parts of, or the entirety of, my recent past projec…
