Or Erlang for even less noise ;) -module(math). sum(A, B) -> A + B.

Exact conversation I had with support after they suspended me after I sold something for the first time, but before I mailed the item. Its like they just randomly permanently suspe…

Agreed, sounds like Orleans. See https://github.com/erleans/erleans :) Also for general writing on erlang and k8s: https://adoptingerlang.org/docs/production/ -- I try to explain w…

Other replies are a bit outdated. It got a lot easier in OTP-23 to go without EPMD, https://blog.erlware.org/epmdlessless/ -- if you run with the same port. If not using the same p…

Try both. It may be because I've been doing Erlang so long but I still prefer it and its tools (like rebar3 and Common Test). I find the syntax more consistent, less verbose and th…

Not a big deal but, it was actually a bug in relx that caused it to be included (accidentally copying the erts dir from the symlink/copy in the _build/ /rel/ / dir instead of from …

4. The compiler should not be included and neither should the headers. Unless a user explicitly wants to include the compiler and also have a C compiler on the node in order to com…

> Why are there 55 c-header files in the directory of the erts? That shouldn't be the case anymore. It was a bug in rebar3 at one point and I think `mix release` may have copied sa…

makeself ( https://makeself.io/ ) is a generic way to do this for Linux that works for any Erlang/Elixir release -- meaning no use of mix or rebar3: https://gist.github.com/tslough…

Not really worth it since distributed mnesia is basically CA (in terms of CAP) which shouldn't be a thing, but is in the case of mnesia :)

Curious why they suggest a reverse proxy. It may be a holdover from a time before Erlang SSL got so many improvements? Heroku moved SSL termination to Erlang from ELB's and saw gre…

If you get to choose your infrastructure that may be fine. If you don't and you work in even a medium size company you likely work with what they have, which is increasingly kubern…

There are some performance related topics covered in the Docker chapter regarding schedulers. And there are improvements already merged for Erlang 23 to remove the need for as much…

It is not going against the grain. Using release upgrades (upgrading a release without restarting the VM -- unless the version of erts has changed) should only be used where necess…

Hi, one of the authors here, the Docker chapter and soon to come Kubernetes chapter hopefully shed some light on this very question. They are not alternatives, docker and k8s compl…

For 'heart' here I'm referring to the heart program that'll start if you run erl with `-heart` http://erlang.org/doc/man/heart.html -- it will restart a down node. I think part of …

Sure, you can write it yourself, and probably it is even easier to write in Erlang -- up to a limit due to the issues with distributed Erlang discussed above. I worry about, and ha…

> How much have you used BEAM? Over a decade professionally. The closest thing Erlang has to it is pool http://erlang.org/doc/man/pool.html

Right, they do, that is why containers are still useful to releases for deployment.

Deployment doesn't overlap. Erlang releases bundle up your code but you still need libraries like openssl, to have a nice bundle that can actually just run anywhere Docker is the w…

Yes, check out http://partisan.cloud/ . Erlang distribution was not designed for the cloud.

They really do not overlap at all. I don't understand why the comparison with docker and Kubernetes continues. Running BEAM on docker in kubernetes is great, a lot is added and ope…

The How I Start guide was just updated for 1.9 http://howistart.org/posts/elixir/1/index.html

It needs to be a matching libc. So a release that includes the Erlang runtime and is built on Debian (glibc) won't run on Alpine (musl).
