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.
I’ve started learning Erlang a few days ago and it’s definitely a very interesting language and very suitable for web development (back end at least). I am going to experiment and eventually settle with one Erlang web framework to use for my next…
It says that Elixir has a tool called elixirc and Erlang has a tool called erlc to compile modules for use. It says immediately after this that you can then run code with the elixir command line tool.
Is there a way to compile a binary executable…
There's a lot of interest these days in Erlang as a language for writing parallel programs on multicore. I've heard people argue that Erlang's message-passing model is easier to program than the dominant shared-memory models such as threads.…
While considering alternatives for Java for a distributed/concurrent/failover/scalable backend environment I discovered Erlang. I've spent some time on books and articles where nearly all of them (even Java addicted guys) says that Erlang is a…
I have a process that needs to do some work every fifteen seconds. I'm currently doing it like this:
-behavior(gen_server).
interval_milliseconds ()-> 15000.
init()->
{ok,
_State = FascinatingStateData,
_TimeoutInterval =…
I have some Ruby and Java background and I'm accustomed to having exact numbers of lines in the error logs.
So, if there is an error in the compiled code, I will see the number of line which caused the exception in the console output.
Like in this…
I am curious why the comma ‹,› is a shortcut for and and not andalso in guard tests.
Since I'd call myself a “C native” I fail to see any shortcomings of short-circuit boolean evaluation.
I compiled some test code using the to_core flag to see what…
With regards to making a game server, it seems Erlang always comes up as a language that is "built for this kind of thing" with its scalability and concurrency features. I don't have experience in either Haskell nor Erlang, but on the surface they…
Message-passing is a fundamental part of Erlang. Alan Kay has argued that message-passing is a concept more important than objects in his view of object-oriented programming (and he "invented" the term!).
Can Erlang be considered an object-oriented…
As I understood from the "Erlang and OTP in action" book, the word behavior refers to:
the behaviour interface, which is a set of functions;
the behaviour implementation, which is the application-specific code (a callback module);
the behaviour…
I am trying to run the following command
rabbitmq-plugins.bat enable rabbitmq_management
and its giving me an error like this:

When I start up my Erlang emulator, there the first bit has a bunch of informational things. (Slightly reformatted for effect.)

I'm trying to run RabbitMQ on a small VPS (512mb RAM) along with Nginx and a few other programs. I've been able to tweak the memory usage of everything else without difficulty, but I can't seem to get RabbitMQ to use any less RAM.
I think I need to…
Part A:
Erlang has a lot of success stories about running concurrent agents e.g. the millions of simultaneous Facebook chats. That's millions of agents, but of course it's not millions of CPUs across a network. I'm having trouble finding metrics on…
