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.

Is it ever possible for 2 commits to have the same hash?
It's far more likely that somebody would try to artificially create a collision. There is code in git to try to detect this https://github.com/cr-marcstevens/sha1collisiondetection

C compiler in .NET
First milestone is to be able to compile this code https://github.com/cr-marcstevens/sha1collisiondetection/ using Cesium.

Hash collisions and exploitations – Instant MD5 collision
For sha1, people made a system where you can detect the patterns that lead to a collision, and (for example) replace it with a different hash only for inputs that would be a problem. https://github.com/cr-marcstevens/sha1collisiondetection i think git does this to eek more life out of sha1.
I imagine you could take a similar counter-cryptnalysis approach to md5. (I am out of my depth here, so there could be reasons this doesnt work for md5 im unaware of)

Apart from using exec.Command, is there a better way to check version of any external system app in /usr/local/bin like fzf or nodejs using go?
I'm saying that Git is on my side of opinion, that's why Git added collision detection (hardened SHA1) and added support for more stronger hashes and Git's goal is transition out of SHA1. The same is with fossil, that added hardened SHA1 since 2017 and by default uses SHA3 for new repositories.

Result of next C23 meeting: typeof is standard, call_once is mandated, char8_t is unsigned, unreachable(), = {}, K&R declarations are gone, int main() is now (void), @, $, ` are now source character, _Noreturn, true/false are keywords
If you know how a C++ lambda works under the hood, you'd understand that C++ lambdas create classes in order to ingest the capture targets then work on it, the code in the Orange C compiler for example does the following:

Pros and Cons of pthreads versus C11 threads?
Pelles C and OrangeC, I don't know about the former, but the latter does it via CreateThread, source.

Confusion in the standard and edge cases you've found in compilers, tests, and other such things
If you want a context as a why the original question, here's a big issue on why it's relevant at all to anyone who isn't developing libcxx.
