Erlang is a general-purpose, garbage-collected programming language and runtime environment, with built-in support for concurrency, distribution and fault tolerance.
Erlang is a general-purpose functional programming language and runtime environment. It has built-in support for concurrency, distribution and fault tolerance. Erlang is used in several large telecommunication systems from Ericsson. Erlang is open source and available for download on GitHub.
From the other languages I program in, I'm used to having ranges. In Python, if I want all numbers one up to 100, I write range(1, 101). Similarly, in Haskell I'd write [1..100] and in Scala I'd write 1 to 100.
I can't find something similar in…
My incomplete understanding is that Twisted, Stackless, Greenlet, Eventlet, Coroutines all make use of async network IO and userland threads that are very lightweight and quick to switch. But I'm not sure what are the differences between them.

I have installed Erlang/OTP and Elixir, and compiled the HelloWorld program into a BEAM using the command:
elixirc test.ex
Which produced a file named Elixir.Hello.beam
How do I run this file?
I'm currently learning Erlang and was wondering about what are some good practices or conventions for unit testing? I am currently using eunit.
To frame this question:
I'm currently writing one unit test module for each function, that way my test…
I am looking to make use of Erlang's hot code swapping feature on a gen_server, so that I don't have to restart it. How should I do that? When I searched, all I could find was one article which mentioned that I need to make use of…
I want to know technical details about garbage collection (GC) and memory management in Erlang/OTP.
But, I cannot find on erlang.org and its documents.
I have found some articles online which talk about GC in a very general manner, such as what…
According to http://elixir-lang.org/getting-started/basic-types.html#atoms:
Atoms are constants where their name is their own value. Some other
languages call these symbols
I wonder what is the point of have a atom type. Probably to help build a…
I need to pad the output of an integer to a given length.
For example, with a length of 4 digits, the output of the integer 4 is "0004" instead of "4". How can I do this in Erlang?
I'm building native mobile applications in both iOS and Android. These apps require "realtime" updates from and to the server, same as any other network-based application does (Facebook, Twitter, social games like Words with Friends, etc)
I think…
I searched for package management on Erlang and Elixir and got some pointers to rebar rebar3 mix hex and relx etc. Can you help clarify the relationships among them? Where to use what? Is package just synonym to Erlang's application made up of…
