To me it looks like a ZeroMQ client can be written in many languages so you don't need to know Clojure to use it. Therefore the article has an extra barrier to entry for understanding the content because more people understand OOP languages like Java than Clojure.

I guess my point is, don't skim the article and think it's not for you because you don't know Clojure. Here's a list of languages it supports ( http://zguide.zeromq.org/page:all#Ask-and-Ye-Shall-Receive ):

C++ | C# | Clojure | CL | Delphi | Erlang | F# | Felix | Go | Haskell | Haxe | Java | Lua | Node.js | Objective-C | Perl | PHP | Python | Q | Racket | Ruby | Scala | Tcl | Ada | Basic | ooc

Here is a more complete list of language bindings taken from http://www.zeromq.org/bindings:_start

Ada, Bash, Basic, C, Chicken Scheme, Common Lisp, C#, C++, D, Delphi, Erlang, F#, Felix, Flex (ActionScript), Go, Guile Scheme, Haskell, Haxe, Java, JavaScript (Node, Flash), Julia, LabVIEW, Lua, Nimrod, Objective-C, Objective Caml, ooc, Perl, PHP, Python, Q, Racket, R, REBOL (2 and 3), Red, Ruby, Scala, Smalltalk, Tcl, XPCOM

OP here, thanks for making that clear. I intentionally tried to keep the Clojure code as generally easy to read as possible, and aside from the big Clojure win (more specifically, functional programming win) towards the end, the code is pretty generic ZeroMQ stuff. I suppose it's not a coincidence that the ZeroMQ docs has the code snippets available in many programming languages :)

I have to confess that I, as a non-Clojure-speaker, found it much less interesting after seeing that your example was in Clojure. Using less common languages as examples makes it feel like it's in that big world of amusing side projects instead of something trying to be mainstream. Not on purpose, it's subconscious.

OTOH, Clojure gets more common as more people use it in examples. Subconsciously, if you keep seeing this strange language every other example code then you start to think that maybe it's not so side-projecty after all.

That's really not fair, to be honest. The ony way for small languages to break through is to get a lot of exposure so that people start using them.

On the contrary, if I see someone writing in Clojure or Scala it is a good indicator that they can be taken seriously.

I wrote an ATS binding which I use in a number of projects: https://github.com/doublec/ats-libzmq

I attempted to use ATS features to make sure resources are cleaned up and msg data usage is statically checked for correct sizes, etc.

Is it now possible to use ZeroMQ in JVM languages without JNI? I used ZeroMQ with Java 2 years ago and had to use JNI to make it work. (Which I did not like).

Yes, you can. The ZeroMQ git repository now contains a pure Java implementation of ZMTP/2.0 which aims to be compatible with libzmq 3.2.2.

I've recently started to migrate my ZeroMQ/JNI to pure JeroMQ and I have a few simple components in production already.

OP here, the examples are using JeroMQ. Actually, that's a lie, I use JZMQ. But the APIs are identical :)

OT, but someone should go update the Golang version to use zerocopy.
