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.

Even the simplest possible assembly program will/can have a console window. How exactly?
You might find the source code for FreeDOS of interest for learning more about how the low-level access to the interrupt services worked. Specifically, console.asm installs a character write routine (which calls BIOS INT 10h under the hood).

Trying to run FreeDOS off CF Card on 286 homebrew system --- Question about bootloader and drive geometry information
Looking at https://github.com/FDOS/kernel/blob/master/boot/boot.asm, I see %define statements for this type of information, but I'm not sure how these memory locations are normally populated with proper values. Is this something that Sys does when preparing the CF card? Or should the BIOS populate this information when loading the boot loader?

"My Reaction to Dr. Stroustrup’s Recent Memory Safety Comments"
That's where I'm coming from. FreeDOS still gets occasional commits once per few months but is not really developed anymore. Watcom C still seems like it's actively developed, but it's not clear what they are trying to achieve if they are not even interested in what's happening in C/C++ world!

How to Port to ARM (Just Curious, not ready to do it yet)
Here's the code for the kernel https://github.com/FDOS/kernel/ You will have to entirely rewrite the Assembly code since it is x86 assembly (Netwide Assembler is great, but not for ARM). Namely boot code is assembly. The kernel does compile under multiple compilers. I'm not too sure if ARM platforms handle this, but I would look at the Linux kernel for boot code on ARM.

Are DOS utilities open source.
"DOS" is a little bit of a general term. Microsoft's product, MS-DOS, is not Free Software. But there are other implementations, including FreeDOS, which is compatible with MS-DOS.

Quants use Rust; Devs use C++ - Hey, it's a compromise!
If you are comparing hoops that library authors need to jump through in both languages, you can easily make the real-world comparison in the other direction, by comparing Rust's Option with C++'s std::optional (an exercise left for the reader): Rust std: https://github.com/rust-lang/rust/blob/master/library/core/src/option.rs libcxx: https://github.com/llvm-mirror/libcxx/blob/master/include/optional

My favorite prime number generator
My favorite prime number generator is the undocumented __next_prime():
https://github.com/llvm-mirror/libcxx/blob/78d6a7767ed57b501...
There is no good reason to use this one except in a code golf environment that includes all headers by default, which is where I learned about it.

"My Reaction to Dr. Stroustrup’s Recent Memory Safety Comments"
I once read a Strousroup quote amounting to "If you understand std::vector, then you understand C++". I thought surely he couldn't have meant the interface but the implentation, googled that llvm's implementation is considered nice and clean, had a look, and noped straight out of there.

RFC: C++ Buffer Hardening
> For example, accessing a std::span or a std::vector outside of its bounds would abort the program, and so would accessing an empty std::optional.
I don't really understand the difference with libc++, libstdc++ and msvc stl's respective debug modes, they already do exactly these checks :
- https://github.com/llvm-mirror/libcxx/blob/78d6a7767ed57b501...
- https://github.com/gcc-mirror/gcc/blob/966010b2eb4a4c52f139b...
- Why is std::array implemented as a struct instead of a class?

C++ Concurrency Model on x86 for Dummies
I mean it's not hard to read the source for your platform. On Linux/x86_64/libc++ it's roughly:
- https://github.com/llvm-mirror/libcxx/blob/master/include/__...
- https://sourceware.org/git/?p=glibc.git;a=blob_plain;f=nptl/...
I don't particularly care to comb through it to see if anything has changed, but historically it was a a little spin-CAS to make the non-contended path fast and then dropping into a https://en.wikipedia.org/wiki/Futex, which is about as good as it gets for staying mostly in userspace but still letting it be scheduler aware so you're not burning up a core busy-polling, which is what often happens when people try to roll their own shit.
Google wants a bit more latitude on the heuristics and degrees of freedom around read/write ownership, so they did it like this: https://github.com/abseil/abseil-cpp/blob/master/absl/synchr... which is quite a bit better commented/legible.
If anyone reading this can do better than the `abseil-cpp` folks, not only would Google take their PR, they'd probably offer them a job.
