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 is your CI/CD pipeline setup and how are you handling larger binaries? are smaller game dev studios just brute forcing through LFS and building for each test?
Don't get me wrong, I'm a big fan of automated tests where it makes sense. I wrote a scripting language that I use for my personal game projects, and I never would have been able to do it if it weren't for the battery of tests for every feature, error, and corner case I could think of. But games are rarely like other software, with hard rules about what is "correct" or "incorrect". And it would be a nightmare to try to keep up with designers, constantly tweaking and tuning, so what's "correct" is literally a day to day, constantly moving target.

any modern procedural programming languages?
A second trial for you might be Jinx. Depending on your definition of procedural, Jinx is 100% only procedural. https://jamesboer.github.io/Jinx/

Which phases/stages does your programming language use?
Jinx (embeddable scripting language) works as following:
- How do I create a file that will automatically compile and run my c++ program when I double click it?
-
Is I already know C and OOP, do I basically already know C++?
Feel free to look at my own interpreter, written in modern C++. You're welcome to ask me if you have any questions.

I'm curious what a gameplay programmer would use a scripting language for
I use my own scripting language more like content, especially for things like one-off events and behaviors. Example: scripting special behaviors for a boss fight, or a room with a unique trap in it, or any other sort of one-off behavior that would be overkill for C++, but too complex for most other types of data-driven content. These days, visual scripting also helps to fill in these gaps between content and procedure.

What are the best free books for learning to write interpreters in C++?
You're welcome to look at my scripting language Jinx, written in modern C++. Just let me know if you have specific questions. Data flow is JxLexer.cpp -> JxParser.cpp -> JxScript.cpp. Most everything else is implementation details. Also, note the parer is pretty complex, mostly because Jinx has a crazily flexible syntax for functions.

Design examples for runtime scripting
Feel free to look at Jinx if you want an example of what I consider a fairly easy-to-use and integrate scripting system. Obviously, I'm a bit biased since I wrote it.

Is just UTF-8 support good enough?
If you're working in UTF-8 internally, you could just write your own UTF-16 to UTF-8 conversion functions to convert strings at API boundaries. I did this in my scripting language because I didn't want to bring in dependencies.

Appending to an std:string character-by-character: how does the capacity grow?
Yeah, it's nice! And Abseil does it, IFF you use LLVM libc++.

The standard adopted it as resize_and_overwrite. Which I think is a little clunky.

Shaving 40% Off Google’s B-Tree Implementation with Go Generics
This may be confusing to those familiar with Google's libraries. The baseline is the Go BTree, which I personally never heard of until just now, not the C++ absl::btree_set. The benchmarks aren't directly comparable, but the C++ version also comes with good microbenchmark coverage.

[R] AlphaDev discovers faster sorting algorithms
I wouldn't say it's that cryptic. It's just a few bitwise rotations/shifts/xor operations.

Deepmind Alphadev: Faster sorting algorithms discovered using deep RL
You can see hashing optimizations as well https://www.deepmind.com/blog/alphadev-discovers-faster-sort..., https://github.com/abseil/abseil-cpp/commit/74eee2aff683cc7d...
I was one of the members who reviewed expertly what has been done both in sorting and hashing. Overall it's more about assembly, finding missed compiler optimizations and balancing between correctness and distribution (in hashing in particular).
It was not revolutionary in a sense it hasn't found completely new approaches but converged to something incomprehensible for humans but relatively good for performance which proves the point that optimal programs are very inhuman.
Note that for instructions in sorting, removing them does not always lead to better performance, for example, instructions can run in parallel and the effect can be less profound. Benchmarks can lie and compiler could do something differently when recompiling the sort3 function which was changed. There was some evidence that the effect can come from the other side.
For hashing it was even funnier, very small strings up to 64 bit already used 3 instructions like add some constant -> multiply 64x64 -> xor upper/lower. For bigger ones the question becomes more complicated, that's why 9-16 was a better spot and it simplified from 2 multiplications to just one and a rotation. Distribution on real workloads was good, it almost passed smhasher and we decided it was good enough to try out in prod. We did not rollback as you can see from abseil :)
But even given all that, it was fascinating to watch how this system was searching and was able to find particular programs can be further simplified. Kudos to everyone involved, it's a great incremental change that can bring more results in the future.
