Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

A Modern High-Performance Open Source Message Queuing System
Hi, one of the authors here. BlazingMQ depends on two other open source C++ libraries: https://github.com/bloomberg/bde and https://github.com/bloomberg/ntf-core. I believe documentation writer wanted to highlight that BlazingMQ does not depend on frameworks like ZooKeeper, etc.

Announcing YOMM2 version 1.3.1
It would be easy to make the runtime use polymorphic allocators, one for the temporary objects created by update_methods, and another for the hash and dispatch tables. The first allocator could use the stack (like this), and the second a block in the BSS segment.

Bloomberg finally opensourced memray —a new versatile memory profile for Python
I'm pretty sure they use C++ very extensively. They have their own C++ standard library for example. I'm not aware of them using FORTRAN or C. Do you have a reference for that?

What language best suits for fintech products and services?
No first-hand experience, but C++ is definitely a player. Check out John Lakos and bloomberg/bde. He was a force behind the improved allocators in C++11 and beyond. That repo I linked is a beast of a codebase (:

Bloomberg London
If I remember correctly, BDE ( https://github.com/bloomberg/bde ) is developed in London's office and definitely the team that works on it is one of the most experienced in the company.

Lightweight and fast AMQP (0-9-1) server
Slightly OT:
Are ZeroMQ and NanoMQ still widely used (and recommended)?

ZeroMQ – Relicense from LGPL3 and exceptions to MPL 2.0
Remarkable, up until recently, requests for a new release were sumewhat brusquely rejected and marked as spam.
https://github.com/zeromq/libzmq/issues/4455
I wonder what made the maintainer change his mind.

Essentials of Object Oriented and Functional Programming: A Guide to Modular Code
FP Libraries: gRPC, ZeroMQ, and AREG are examples of libraries with a special focus on providing possibilities for Interprocess Communication. Developed using C++, they facilitate communication through predefined APIs, emphasizing functional programming concepts.

A Modern High-Performance Open Source Message Queuing System
Unlikely, but they seem to be different things altogether. BlazingMQ appears to be a traditional message queue (think ActiveMQ), with message peristence. ZeroMQ is more of a network middleware (think Tibco Rendezvous), and does not include persistence.
BlazingMQ also appears to be more of a "platform" or "service" that an app can use (sort of like Oracle, say) -- ZeroMQ includes libraries that one can use to build an app, service or platform, but none is provided "out of the box".
Which makes it harder to get started with ZeroMQ, since by definition every ZeroMQ app is essentially built "from scratch".
If you're interested in ZeroMQ, you may want to check out OZ (https://github.com/nyfix/OZ), which is a Rendezvous-like platform that uses the OpenMAMA API (https://github.com/finos/OpenMAMA) and ZeroMQ (https://github.com/zeromq/libzmq) transport to provide a full-featured network middleware implementation. OZ has been used in our shop since 2020 handling approx 50MM high-value messages per day on our global FIX network.

What they don't teach you about sockets
I think the situation is more subtle than the poster admits.
No, ZeroMQ and successors do not tell you about socket state. You can't detect disconnection or reconnection. But then if a TCP connection fails in some way that does not lead to disconnection (packets getting dropped, remote machine powers down), it can't possibly tell you about that either, but you still need to deal with it. So in any case, you need some sort of application-level error detection and recovery; you need heartbeats, and serial numbers in messages, and a protocol for explicitly restarting a connection and performing the initial handshake. And once you have that, explicit connection events from ZeroMQ are much less important.
Admittedly, given that this is a TCP transport, reporting reconnections would still be useful, because TCP won't ever drop messages from the interior of a sequence itself (if it delivers 15, it has delivered 1 - 14 already), so you shouldn't need the serial numbers.
And if it's really not possible to detect authentication failures, than that seems rubbish. And it seems that is indeed the case: https://github.com/zeromq/libzmq/issues/3505
