ZeroMQ: High-Performance Concurrency Framework

ZeroMQ was followed by nanomsg ( https://nanomsg.org/ ) and nng ( https://nng.nanomsg.org/ ) Some of Martin's rationale here: https://250bpm.com/blog:23/index.html ZeroMQ is still widely used and popular, but I am not sure if it is still actively developed.

I've used zeromq, nanomsg, and nng. The differences are subtle and focused on native library support, background threading model, and other systems level things.

All of them are based on specs that are widely published. I've had zero problems implementing real robotic systems in nng, zmq, etc.

And it is so damn easy to use it's amazing to me the whole world doesn't use it.

Anything new with ZeroMQ? It's been around for a long time.

I'm pretty sure the world doesn't use it more because it doesn't have a flashy marketing campaign and trendy developer tools/libraries don't have a plugin for it. If a whole bunch of developers aren't writing blog posts about it, does it even exist? Plus, it's old, so it's bad.

The licensing was changed about nine months ago. LGPL-3.0+ is out and MPL 2.0 is in. Very thankful for that.

I looked at 0mq et al, and what I couldn't understand is why sockets have a single exclusive type. Like say I want a process that generally sends out streaming broadcast updates, but is also controlled through request-reply. It would need two separate sockets. Then I'd have to reinvent some sort of ordering protocol across the two (as well as program logic to handle the partially-connected state), which would defeat much of the point of using 0mq?

Ah ok. Was wondering why this was on HN front page today. :)

Why are you thankful for the MPL instead of the LGPL? Is there any advantage to the MPL other than being easier to incorporate MPL code into proprietary software?
