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.

ToaruOS 2.0
From an old FAQ page[1] for TauruOS:
> I wrote ToaruOS at a time when I was much more competent at C than C++. I still think that's true. At this point, the effort of rewriting datastructures to make use of C++ functionality would not be a good use of time - and writing userspace code in C++ in ToaruOS-NIH is not yet possible as I have yet to get a C++ standard library set up.

C-Macs – a pure C macOS application
Even then, MFC and C++/CX were the only productive ways to use it from Microsoft SDKs.
.NET isn't as convenient as VB 6 was, fully embracing COM as the VBX replacement model, technically introduced in VB5, but still some stuff was lacking.
Then there is Delphi and C++ Builder.
It beat me that having doubled down on COM since how Longhorn went down, and Windows team getting their way doing avoiding .NET to take over, they hardly managed to create nice tooling as the competition.
Editing IDL files with a Notepad like experience, manually merging generated code, and a couple of frameworks that barely go beyond yet another way to do AddRef/Release/QueryInterface and aggregation.
Meanwhile D-BUS, XPC and AIDL, provide much better dev experience.
Pity that Borland products are kind of tainted due to mismanagement decisions, otherwise maybe fixing COM dev experience would already been seriously taken by VS team.
Ah, nowadays WIL is probably the best approach when having only to consume COM.

ntoskrnl7/crtsys: C/C++ Runtime library for system file (Windows Kernel Driver)
Have a look at WIL for a C++ library used by Microsoft themselves, including kernel development.
-
I'm thinking about using a struct to hold allocated memory and guaranteeing it will be released when the struct goes out of scope, as an alternative to smart pointers. What do you think?
I'm digging for more information and it looks like Microsoft's created a way to handle the problems I'm trying to address with this: https://github.com/Microsoft/wil/wiki/RAII-resource-wrappers

Unwrapping WinUI3 for C++
Since we are on this subject, those that need a nice C++ library to deal with COM in VC++, are better served with WIL.

RISC-V J extension – Instructions for JITs
Not since Vista.
https://docs.microsoft.com/en-us/cpp/build/reference/kernel-...
> Creates a binary that can be executed in the Windows kernel. The code in the current project gets compiled and linked by using a simplified set of C++ language features that are specific to code that runs in kernel mode.
And then there is WIL, https://github.com/microsoft/wil
https://community.osr.com/discussion/291326/the-new-wil-libr...
> First off, let me point out that this library is used to implement large parts of the OS. There are hundreds of developers here who use it. So unlike, uh, some other things that get tossed onto github, this project is not likely to wither and die tomorrow.
> There are, however, only a handful of kernel developers working on the library, so the kernel support has been coming along much slower. I'd like to expand the existing kernel features in depth ....

ToaruOS 2.0
> Plus C++ standard library can't be used anyway and auto pointers aren't really that much of a concern at the kernel level
https://github.com/microsoft/wil
"Ah, but that isn't used on the Windows kernel" would be the expected reply, well
https://community.osr.com/discussion/291326/the-new-wil-libr...
"Microsoft's toolchain does not ship a copy of the STL that works in kernel mode. Partly this is because the kernel's CRT doesn't support C++ exceptions. (And partly this is because I/O is wildly different in kernel, so you'd have to rewrite the implementation of all the I/O libraries.)
But for kernel developers, wil ships a subset of an STL implementation. To avoid conflicting with the real STL, it's available under the wistd namespace. The rule of thumb is that wistd::foo is a drop-in replacement for std::foo."

Linux Sucks 2021 – The End of Linux Is Nigh
Windows is a mix of legacy C code, which started to be migrated into C++ around the Vista time (hence /kernel in VC++) and .NET/COM (WinRT is basically COM with some extras).
Modern kernel code makes use of WIL.
