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.

Atomics and Concurrency
If you're interested about lock-free data structures, I wrote [lockfree](https://github.com/DNedic/lockfree) a collection of lock-free data structures meant to be readable and both hosted system and embedded friendly.
-
Optimizing a Ring Buffer for Throughput
If you want more than a spsc queue, I've written `lockfree`, a collection of SPSC and MPMC data structures along the same principles the author here used:https://github.com/DNedic/lockfree.
The library is written in standard C++11 (but additional API's for higher C++ versions have been added), uses no dynamic allocation and is configurable so it is both big metal and deeply embedded friendly.

A collection of lock-free data structures written in standard C++11
- A lot of code won't work for types with no default constructors, but that is at least compile error
- Using memcpy[0] for arbitrary types is just wrong, see [1]

Lock-free data structures
My friend wrote a few lock-free data structures and he is now looking for some feedback. Here is the link: https://github.com/DNedic/lockfree

OpenPicoRTOS: 'cause the world DEFINITELY needs another RTOS !
If you're interested in how to do that you can check out a library of mine: https://github.com/DNedic/lfbb (although you don't need to bother with memory ordering if you don't want, you can just use the sequential consistency model).

How do you handle data coupling between RTOS tasks?
You might be interested to take a look at this if efficiency is one of your goals: https://github.com/DNedic/lfbb

Library for generic ringbuffer that can be filled via DMA?
I have exactly what you are looking for https://github.com/DNedic/lfbb

Best practices on loosely coupling the high-level modules on a sensor-packager-transmitter embedded c device.
I don't see a reason SensorCollector should send a flag when there is enough data to send, the circular buffer object should be able to tell you when there is enough data to send and it should not be coupled to your specific applicaton. For situations where you want the data to always be contigous and need a general purpose circular buffer, you can take a look at a library i wrote: https://github.com/DNedic/lfbb
