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.

What are some concepts/tools/tricks that are frequently used in C/C++ code for embedded software?
The only all-C++ RTOS implementation (that I've come across) is Distortos..
lockfree
- A lock-free ring-buffer with contiguous reservations (2019)
-
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
- A collection of lock-free data structures written in standard c++11
- A collection of embedded friendly lock-free data structures written in standard C++11
What are some alternatives?
micro-gl - Headers Only C++11 CPU Vector Graphics. no std-lib, no FPU and no GPU required !
rc_event_queue - VecDeque-like fast, unbounded, mpmc/spmc concurent FIFO message queue. Lockless reads, write-lock writes.
l4re-core - The core components of the L4Re operating system.
glibc - GNU Libc
Postform - Postponed formatting experiments with string interning in C++. Inspired by the defmt Rust crate
real-time-cpp - Source code for the book Real-Time C++, by Christopher Kormanyos
tlaplus - TLC is a model checker for specifications written in TLA+. The TLA+Toolbox is an IDE for TLA+.
BOSSA - BOSSA is a flash programming utility for Atmel's SAM family of flash-based ARM microcontrollers. The motivation behind BOSSA is to create a simple, easy-to-use, open source utility to replace Atmel's SAM-BA software. BOSSA is an acronym for Basic Open Source SAM-BA Application to reflect that goal.
Ring-Buffer - A simple ring buffer (circular buffer) designed for embedded systems.
VibSense - VibSense: A ~3kHz wireless vibration sensor powered by M5stack-core & MPU6886, optimized with RTOS for real-time measurements.
multiversion-concurrency-control - Implementation of multiversion concurrency control, Raft, Left Right concurrency Hashmaps and a multi consumer multi producer Ringbuffer, concurrent and parallel load-balanced loops, parallel actors implementation in Main.java, Actor2.java and a parallel interpreter
