By looking at the comments you'd assume a new version of Phoenix got released.
Agreed. It's getting pretty annoying. Every Rails post that hits the front page now feels like it's getting hijacked/side-tracked by Elixir/Phoenix evangelists.

Re: Rails 5.0: Action Cable, API mode, and more
#82We've moved all of our backend offerings from Rails to Elixir/Phoenix. Despite some questioning the value of anything below 100ms response times there is a lot of data backing up the idea that Elixir/Phoenix can lead to a more maintainable and more economical solution. I spoke about this recently at RailsConf: https://www.youtube.com/watch?v=OxhTQdcieQE Don't get me wrong, I think Rails is an amazing technology but i…

#83I personally really love using Rails. It's been very productive for me over the past several years I've been able to make a living off of this. I see a lot of comments here about Elixir/Phoenix. Is the performance gain really that big? I currently serve 2-3 mil requests on Rails per day on around $200 worth of servers with at least one database call per request. In defense of Rails, there are so many libraries out th…
It's around 12 times faster in the general sense. Your mileage may vary. If you spend $200 you could theoretically hosting the same product on $50 worth of hardware.
That saving of $150 is equivalent to one hour of pro dev work time. It's hardly worth converting unless Elxir / Phoenix is much more productive and maintainable.

That's awesome! Michael Hartl is such a great member of the community.
A lot of name dropping on hacker news goes over me head because I've only been in the community a few years. I feel like Michael Hartl will be the name I drop 15 years from now whenever I'm discussing Rails and the origin of "modern" web development.
I agree. Have you heard his interview[1] on Software Engineering Daily? He's a really interesting guy.

#85Concurrency aside, why is Elixir preferred over Ruby when it doesn't even have a native array implementation? No, lists and tuples are no substitute nor are maps with numeric keys as Jose has suggested. If you want an array in Elixir your only option is Erlang's implementation which ain't pretty - http://erlang.org/doc/man/array.html. When I raised this issue in the mailing list and on IRC the response was invariably a definsive "I've never needed arrays", "We use tuples for most things in Elixir" or "Array performance characteristics are difficult to optimise in a functional language such as Elixir". I just find this disappointing.

#86I am very jealous as a Django developer. They decided to keep Channels as a third-party package after all, maintained by a single guy :(

Sorry if seems a bit off-topic but I raised this issue because there have been a lot of posts about Rails devs switching to Elixir/Phoenix.

I've just started learning Elixir out of interest so I can't quite answer your question. However, I'd like to ask: what have you found to be difficult to do using the Elixir types such as tuples, list, keyword lists, and maps that would otherwise be easy to do using arrays? I'm asking out of genuine curiosity because I've specifically noticed a lack of arrays when learning Elixir and I'm quite used to using them in other languages.

Python lacks a native array too but its list type seems to do just fine. What is it you want to do that you that requires an array?

Why do you want an array? You mean you want a memory area with adjacent cells layed out, to talk to C perhaps? Perhaps might want a list, a binary, or a sorted set, a tuple, a map and so on. You have to tell a bit more about your use case.
I used Erlang for many years, and in the last one full time. Not one time have I needed an "array". It seems you picked one odd feature no-one uses and are upset about it, I thik it is just a small misunderstand, if you share a bit more about what you are trying to do, you'll get more help.
> I just find this disappointing
Did you explain your use case to them. If you just said "I need an array" I see their response as perfectly rational. And from what I've seen, that is probably the friendliest and most approachable community, especially for newcomers.
