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.

This isn’t the way to speed up Rust compile times
> What can I use to cache with MSVC that isn't Incredibuild?
Ccache works, but if you use the Visual Studio C++ compiler you need to configure your build to be cacheable.

Flutter or React Native
That ecosystem now is too young. All these things must be configured by an automatic installer. Packages and pods need to be tested before release, etc. Previous was 80 min compilation time of the Firestore package. Solved with https://ccache.dev/. But why Dart developers must know, how to install and configure object cache for C++ compilers?

Distcc: A fast, free distributed C/C++ compiler

https://github.com/icecc/icecream - another option that does what distcc does, but aimed at a somewhat different use case.
https://ccache.dev/ - a similar idea but provides caching of build outputs instead of distributing builds. You can use it together with distcc to achieve even better performance.

Boring Python: Code Quality
> All those big changes introduce commits that make git bisect generally slower.
Bisection search is log2(n) so doubling the number of commits should only add one more bisection step, yes?
> Which might be awful if you also have some C code to recompile at every step of bisecting.
That reminds me, I've got to try out ccache (https://ccache.dev/ ) for my project. My full compile is one minute, but the three files that take longest to compiler rarely change.

Ccache – a fast C/C++ compiler cache
I worked with the internals of this some 16 years ago, maintaining a customized version at Zeugma Systems. Some change of mine was reworked by someone and upstreamed:

IncludeGuardian - improve build times by removing expensive includes
ClangBuildAnalyzer reports on parsing, build, and link time, whereas IncludeGuardian only reports on parsing time.

"Fast Kernel Headers" Tree -v1: Eliminate the Linux kernel's "Dependency Hell"
https://github.com/aras-p/ClangBuildAnalyzer is a very useful tool to quantify the cost of different headers (and other costly parts of the compile such as template instantiations). It doesn’t help with actually fixing such problems, but it’s a pretty good ruler to measure where the time is spent.

sccache - Sccache is a ccache-like tool. It is used as a compiler wrapper and avoids compilation when possible. Sccache has the capability to utilize caching in remote storage environments, including various cloud storage options, or alternatively, in local storage.
Bear - Bear is a tool that generates a compilation database for clang tooling.
buildcache - A build cache
sol2 - Sol3 (sol2 v3.0) - a C++ <-> Lua API wrapper with advanced features and top notch performance - is here, and it's great! Documentation:
Redis - Redis is an in-memory database that persists on disk. The data model is key-value, but many different kind of values are supported: Strings, Lists, Sets, Sorted Sets, Hashes, Streams, HyperLogLogs, Bitmaps.
