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.

Ask HN: Good sources of math exercises for ~10-17 y/o?
Could solve Project Euler problems in Lua - aka, the easiest programming language to learn
https://projecteuler.net/
Alternatively, you could get a homeschool math textbook. They're written differently because the assumption is that the kid is going to have to teach themselves, and as such they are significantly more thorough and easy to understand. I highly recommend them. Don't get the kind that are "workbooks", those are usually trash. Find a good textbook that the kid can write in their own notebook for and sell after they're done with it. They'll learn how Ebay works, and algebra!

Ask HN: Are there any websites for SQL puzzle games?
A coworker used to solve Project Euler[1] problems using SQL while they waited for DB indexes to rebuild or tables to restore from backup in the middle of the night.

New to programming, starting with C++
If you want some recommendations on how to learn it best, I really suggest jsut using it and googling how to do the things you dont know how to do as you work. Right now, the advent of code is happening and its one of the best ways to practice and learn: https://adventofcode.com/ Another thing you might want to try is Project Euler: https://projecteuler.net
- Any programs or websites to practice programming?

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.
