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.

Deploy multi-platform applications with C++ (desktop, mobile and web). An example with Dear ImGui
I wouldn't say that CMake isn't that painful for the deployment stage. I have successfully deployed an open source project on Windows, Mac, Linux, Android, and iOS.

Introducing TeaScript C++ Library
It's a very old project and a VERY basic engine. TBH, engines like godot do a much better job, have their own scripting language (to hide away C++), but still let you write some native code if need be. For TeaScript, I'd be more interested in using it to have a more dynamic pipeline for this project, but performance there is absolutely critical since it can mean the difference between 2 minutes an 2 hours.

What are the hallmarks of well written and high quality C++ code?
Does it work as a drop-in replacement? I've got this project here where I'm looking to squeeze more perf from: https://github.com/define-private-public/PSRayTracing

I made a drop in replacement of `std::shared_ptr` to experiment with performance. It wasn't any faster. Why?
While working on a ray tracing implementation, I was interested in replacing out the usage of std::shared_ptr with something else. I've always been told that shared pointers are slow, and this is due to things such as reference counting. The original implementation of this ray tracer used shared pointers quite extensively in the rendering (hot path) code. I didn't want to deviate from the architecture for my implementaiton . Mostly, the pointers are passed around as const-ref objects.

Question about branch prediction for clauses that are either `true` for 100% of the time, or `false` for 100% of the time.
Last year I was working on an implementation of the Ray Tracing in one Weekend book series. I noticed there was a fair amount of sub-optimal code in it, so I took the opportunity to rewrite parts of it to be better optimized. One of the other things I added to the CMake configuration were some compile time flags that could be toggled ON/OFF, as to use either the books code, or my code. e.g. WITH_BOOK_AABB_HIT=True, it would use the books' method AABB-Ray intersection. False, it would use my (faster) one. This allowed anyone else to download the code, toggle the change and easily see the effect it had on performance.

Stories of what happened when you forgot to initialize a variable
Here's my implementation: https://github.com/define-private-public/PSRayTracing It's different, mainly in structure (cleaner) and that it's much more performant. It also allows you to either use the code I wrote (typically faster) or the book's methods with the flip of a compiler flag.

Are We Modules Yet?
If you aren't aware of the c++ core guidelines[1] - it should be on your radar.
Also, it might not be a popular opinion, but I think Bjarne's books are just fine.

Toward a TypeScript for C++"
In addition to the other comments -
TypeScript deliberately takes a "good enough" approach to improving JavaScript, instead of designing an ideal but incompatible approach. For example, its handling of [function parameter bivariance](https://www.typescriptlang.org/docs/handbook/type-compatibil...) is unsound but works much better with the existing JavaScript ecosystem. By contrast, a more academic functional programming language would guarantee a sound type system but would be a huge shift from JavaScript.
By analogy, Herb Sutter is arguing that something like the [C++ Core Guidelines](https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines), with tooling help in this new Cpp2 syntax, can bring real improvements to safety. Something like Rust's borrow checker would bring much stricter guarantees, backed by academic research and careful design, but would be incompatible and a huge adjustment.

MechE student here. Is there benefit to learning C in addition to C++, or can one do everything with C++ that can be done with C?

C++ is everywhere, but noone really talks about it. What are people's thoughts?
Take a look at Effective Modern c++ by Scott Meyers and the ISO c++ core guidelines. These resources are great for learning how to write better, more modern C++. I don't think it would be hard to grasp if you're already familiar with the language, just make sure to actually write some code which makes use of this stuff, otherwise it's easy to forget.

What are some C++ specific antipatterns that might be missed by C#/Java devs?
Look to the C++ Core Guidelines. It's not perfect, it has some flaws, including some sabotaging advice apparently adopted for political reasons. But at least it has some C++ authorities (Bjarne and Herb) as authors.
