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.

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++.
https://github.com/abseil/abseil-cpp/blob/master/absl/string...
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.

Backward compatible implementations of newer standards constructs?
Check out https://abseil.io. It offers absl::optional, which is a backport of std::optional.

3rd Edition of Programming: Principles and Practice Using C++ by Stroustrup
>Maybe take a shot at parsing JSON in C++ and see if the nostalgia survives the process.
I have used this library in the past and was actually pretty easy

Sane C++ Libraries
https://github.com/nlohmann/json
I used this for JSON last time I wrote any C++ a few years ago and it still seems popular. It seemed sane enough to me.

Experience using crow as web server
On the other hand, I'd like to bring in the json library of my choice, e.g. https://github.com/nlohmann/json or https://github.com/danielaparker/jsoncons. So I'd prefer the web server library provides as little as possible in the way of Json support, and certainly doesn't get in the way of using my library of choice. Similarly, I'd like to use my choice of automatic object serialization.

What are some C++ projects with high quality code that I can read through?
I find openMVG very decent, FTXUI might be a good one and nlohmann's json library is also pretty nice. I don't really know of any project that strictly adheres to the core guidelines, except maybe for some of Jason Turner's (sample) projects.

C++ Is Incredible
Please provide us an example of this one minute process you talk about for an example project of opening a JSON file, writing to it and closing it with a library like `nlohmann`s.

palpatine supports config file in JSON format
I worked on my partner’s static site generator, rwar, to implement this feature and she worked on my static site generator – palpatine. I was easily able to do this in rwar which is written in Python. However, I realized that this feature was much harder to implement on palpatine which is written in C++. Samina reached out multiple times seeking help for the broken Cmake configurations and for helping in integrating the nlohmann/json library.
