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.

eCAL ipc framework
New version (5.94) of the high performance interprocess / interhost communication framework eCAL is available. eCAL supports different transport layer like shared memory for interprocess and udp multicast for interhost communication. It does not force the user to use a specific serialization format but supports some of the standards like google protobuf, capnproto or flatbuffers. The API is wrapped to C, C++, Python, C#, Rust and Go (the last two I never tested ;-)). Here you can find all the documentation. Check out the great applications for monitoring, record and replay. eCAL is Apache 2 licensed, repository hosted here. Have fun :-)
- eCAL 5.9.4 released

Should I run ROS on windows, through WSL or on linux with dual boot?
I you just need a fast publish / subscribe framework for windows you can give eCAL a try. The setup is done in less a minute and their is no dependency hell. Just to mention it as alternative. Documentation here

Google Protobuf vs JSON vs [insert candidate here]
I would concider using eCAL since it blasts everything out of the water in terms of performance and comes with some handy tooling for inspection of messages in-travel.

grpc_bench: open-source, objective gRPC benchmark
This really makes me want to try https://github.com/continental/ecal with https://github.com/google/flatbuffers to see how they compare. I also know that gpc for cpp at least stops functioning by about 4 MB of request size. Which I find stupid. What if I want to send uncompressed bitmaps!

Announcing Eclipse iceoryx 1.0.0
Congratulations. Well done. eCAL will update as soon as possible to the new release. The new custom header and the n:m pub/sub support are really welcome new features.

Learn Modern C++
I have not done a "desktop" program in 25+ years and never using C++ (or C), since then I'm mostly a web developer (PHP,Elixir, JS, Kotlin etc).
I'm currently doing a C++ audio plugin with the Juce framework.
This website has been a good resource, alongside https://www.learncpp.com
But I was actually close to give up before using those two things:
- https://github.com/nlohmann/json : my plugin use a json api backend and the Juce json implementation is atrocious (apparently because of being born in previous c++ version), but this library is GREAT.
- ChatGPT 4. I'm not sure I would have "succeeded" without it, at least not in a reasonable time frame. ChatGPT 3.5 is slow and does not give good results for my use case but 4 is impressive. And I use in a very dumb way, just posing question in the web UI. I probably could have it directly in MSVC?
Also I must say, for all its flaws, I have a renewed appreciation for doing UI on the web ;)

What C++ library do you wish existed but hasn’t been created yet?
https://github.com/nlohmann/json works well for me

It is either a clever technique or a sad failure
Here is one popular C++ library (nlohmann/json) removing its use.

How to compile project to separate files to prevent having single large executable as a result?
Before going into binary serialization I suggest you to get comfortable with serialization to text. You can try to write your data to text files and read them in again. Then after you get an idea of how this works you can try to use a library that writes to XML or json, e.g. nlohmann json
- What are some ways I can serialize objects?

Download the single header file json.hpp from https://github.com/nlohmann/json/releases and place it in your project directory or an include directory.
