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.

Implementing OTel Trace Context Propagation Through Message Brokers with Go
Several message brokers, such as NATS and database queues, are not supported by OpenTelemetry (OTel) SDKs. This article will guide you on how to use context propagation explicitly with these message queues.

Interview with Sebastian Holstein, Founder of Qaze
During our interview, we referred to NATS quite a few times! If you want to learn more about it, Sebastian suggests this tutorial series.

Sequential and parallel execution of long-running shell commands
Pueue dumps the state of the queue to the disk as JSON every time the state changes, so when you have a lot of queued jobs this results in considerable disk io. I actually changed it to compress the state file via zstd which helped quite a bit but then eventually just moved on to running NATS [1] locally.

Revolutionizing Real-Time Alerts with AI, NATs and Streamlit
Imagine you have an AI-powered personal alerting chat assistant that interacts using up-to-date data. Whether it's a big move in the stock market that affects your investments, any significant change on your shared SharePoint documents, or discounts on Amazon you were waiting for, the application is designed to keep you informed and alert you about any significant changes based on the criteria you set in advance using your natural language. In this post, we will learn how to build a full-stack event-driven weather alert chat application in Python using pretty cool tools: Streamlit, NATS, and OpenAI. The app can collect real-time weather information, understand your criteria for alerts using AI, and deliver these alerts to the user interface.

Why wasn't NATS[1] used ?
Written in Go, single-binary deployment... there's a lot to love about NATS !

Introducing “Database Performance at Scale”: A Free, Open Source Book
About cost, see [1]. Also, S3 prices have been increasing and there's been a bunch of alternative offers for object store from other companies. I think people in here (HN) comment often about increasing costs of AWS offerings.
Distributed systems and consensus are inherently hard problem, but there are a lot of implementations that you can study (like Etcd that you mention, or NATS [2], which I've been playing with and looks super cool so far :-p) if you want to understand the internals, on top of many books and papers released.
Again, I never said it was "easy" to build distributed systems, I just don't think there's any esoteric knowledge to what S3 provides.

Is it an antipattern to use the response channel as identifier
I am in a project were nats.io is used. Someone thought, it would be a great idea to link data in an event with data in a response using the response channel name.

Lightweight and fast AMQP (0-9-1) server

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
