Hi, I'm Mariano Guerra, below is my blog, if you want to learn more about me and what I do check a summary here: marianoguerra.github.io or find me on twitter @warianoguerra or Mastodon @marianoguerra@hachyderm.io

State of the BEAM 2017: Survey Results

Intro

You can't improve what you don't measure, and since I think there are areas in the BEAM community (Erlang, Elixir, LFE, Efene, Alpaca, Clojerl et al.) to improve we need to have a better picture of it.

That's why some months ago I decided to create this survey, I told to some people and started researching other "State of the X Community" yearly surveys, I wrote some draft questions and published to some people for feedback, after a couple of rounds I made a Form and ran a test survey for more feedback, after a couple dozen answers I cleared the results and announced it publicly with a weakly reminder on multiple channels.

Result Analysis

We got 423 Responses up to this point.

I present the results of the State of the BEAM Survey 2017 here in two ways:

  • Bar charts sorted by most answers to less

    • On questions with many answers I make a cut at some point

  • Raw data tables sorted by most answers to less

    • Here I did some consolidation of answers to avoid making them too large

I was thinking on doing a deep analysis on the answers but later I realized that if I did an analysis many people would read mine and avoid analyzing it themselves in detail.

Instead I decided to open an analysis thread in some forum and later maybe summarize the most interesting comments.

To ease the discussion I will do some light observations where I see it makes sense and make some questions to open the discussion.

Before diving into the result I want to make explicit two things that may make the results less representative than they should:

1. The "Elixir Effect"

I think the Elixir community is bigger or at least more active than the rest of the BEAM community, because of that and the fact that Elixir already has its own survey, I decided not to promote this survey there, to avoid the number of Elixir specific answers to skew the results and make this survey just be yet another Elixir survey with some BEAMers also replying.

With this clarification, and looking at the answers, I can identify some answers that are from Elixir-only developers, you can see that when some Elixir specific tools appear in the answers (Mix, ExUnit, Distillery, deploy to Heroku etc.), just keep that in mind when analyzing the results.

2. The "Survivorship Bias Effect"

From the wikipedia article on Survivorship bias

Survivorship bias or survival bias is the logical error of concentrating on the people or things that made it past some selection process and overlooking those that did not, typically because of their lack of visibility. This can lead to false conclusions in several different ways. It is a form of selection bias.

Survivorship bias can lead to overly optimistic beliefs because failures are ignored, such as when companies that no longer exist are excluded from analyses of financial performance.

/galleries/state-of-beam-2017/Survivorship-bias.png

The damaged portions of returning planes show locations where they can take a hit and still return home safely; those hit in other places do not survive.

This survey is done on people that wanted to learn Erlang, learned it, and are still active enough on the community to see the survey announcement.

This means that the answers are from the ones that "survived", which makes it really hard to get good feedback on the bad parts of the language, tooling and community since the most affected by it aren't going to stay around to fill this survey.

How to reach those? I don't know, propose solutions on the discussion.

I forgot to ask if I could make public the name of the companies so I won't, but I can say that I got 202 responses and most of them are not duplicates.

Things to improve for next year

  • Ask users if they want their answers available to be distributed in raw form for others to analyze

  • Ask users if I can share publicly the name of the company where they use Erlang

  • Decide what to do about Elixir-only replies, maybe make a question about it

  • Make specific questions regarding better tooling

  • I forgot Russia and Central America options, maybe next time do Latin America?

Let's see the results!

Which languages of the BEAM do you use?

/galleries/state-of-beam-2017/lang.png

Clearly Erlang is the most used language, ignoring the Elixir Effect, I'm kind of disappointed by the lack of users trying alternative languages. More so given the fact that many of the complaints or requests in other questions are already solved by other languages in the ecosystem, for example "better macros" or lisp inspired features being solved by LFE, static/stronger typing or better static analysis being solved by Alpaca, Elixir's pipe operator and a more mainstream syntax being solved by Efene.

My advice to the community, try the other languages, blog/tweet about it and share feedback with their creators, there's a language for each taste!

How would you characterize your use of BEAM Languages today?

/galleries/state-of-beam-2017/use.png

Many people using it for serious stuff, the Open Source answer is really low here but is contradicted by another answer below.

I think I should add another option for something like "experiments", "try new ideas".
