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 do people usually do to separate/abstract platform dependent codes/files
Here is the port - https://github.com/FreeRTOS/FreeRTOS-Kernel/tree/main/portable/ThirdParty/GCC/Posix

TI CC2630: Having trouble deciding Contiki vs TI-RTOS
Freertos has support for generic cortex m3: https://github.com/FreeRTOS/FreeRTOS-Kernel/tree/main/portable/GCC/ARM_CM3 It could very well work almost out of the box with your mcu.

Ted Ts'o: "As an OS engineer, I deeply despise these optimization tricks, since I personally I care about correctness and not corrupting user data far more than I care about execution speed"
the only OS written in iso c i found was RTOS and they have open bug reports due to strict aliasing in simple things like their linked list implementation, which they don't bother to fix because somehow that causes even more problems (?!): https://github.com/FreeRTOS/FreeRTOS-Kernel/pull/54

Arduino or full featured RTOS?
You likely put the requirements of POSIX just to have an excuse. Fyi, FreeRTOS kernel, the only thing you need, is here: https://github.com/FreeRTOS/FreeRTOS-Kernel/

Nutshell custom memory allocators for me
FreeRTOS comes with 5 quite simple reference implementations of the heap memory allocator. You can study how it works.

Using FreeRTOS and dual core RP2040
The main branch is single-core. You're looking for the SMP branch.

C programmers scare me
On non-POSIX systems, malloc & free are implemented differently. EG FreeRTOS has some very simple malloc (and optionally free) implementations, eg heap_2.c (has malloc & free, but doesn't consolidate blocks), or heap_4.c (more complex, tries to prevent fragmentation by consolidating blocks, still less optmized & simpler than the glibc malloc/free used by most Linux systems).

Ask HN: Examples of Microkernels?
This is based on little kernel from recollection (noted somewhere in the docs)

Are there any jobs out there in C++ programming for someone who is primarily a hardware engineer? HFT or any other industry?
I've worked in LK (Little Kernel), which is the basis of the Android and WebOS boot loaders, but is also a reasonable stand-alone operating system, ThreadX, which is a very lightweight RTOS, and one or two others. These were all written in C, but it was also quite a few years ago, so I suspect a good chunk of the industry has moved to C++.

Is “make” or “makefile” like a OS?
You might also want to look into LK ("little kernel"). It's the basis for both the Android and WebOS bootloaders, which I've also worked on. It has multi-threading and I/O but doesn't support user processes. Might be good for embedded systems.
