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.

Open GL tutor request
Obj file parsing isn't really OpenGL... But you can take a look at this GitHub project: https://github.com/tinyobjloader/tinyobjloader

From Blender to OpenGL
For the Blender export part, the simplest 3D model format is OBJ. It's a text format that can be read in only ~100 lines of code. You can use Assimp for this. Or you can use something like tinyobjloader: https://github.com/tinyobjloader/tinyobjloader

[Part 5] Update of my Vulkan toy renderer: Meshlet cone culling, fast_obj, Vulkan dynamic rendering and many more
I've replaced tinyobjloader with fast_obj which speeds up model loading process significantly. Here is a good article comparing different obj loaders.

Texture UV issue
I don't think this is an issue with tinyobjloader but I'm unsure of how to troubleshoot from here. I've been following this tutorial to learn opengl.

oof: real-time, full-color console output for C++
Exampes I've seen are the stb single header libraries, as well as tinyobjloader. The necessity to do this is usually written in the comments at the top of the header file:

How can I get Triangles from OBJ files?
If you´re using tinyobjloader, the documentation here https://github.com/tinyobjloader/tinyobjloader explains how it works. There´s even a triangulate flag.
-
Is there a simple and reliable static object loader out there?
Try Tiny obj loader: https://github.com/tinyobjloader/tinyobjloader

Baking Lighting Data and Color Variations to Vertex Colors
Also, it's possible to store a color per vertex, tinyobjloader supports this extended format for OBJ. But, like you say, how many (if any) OBJ loading programs actually support these vertex colors I suspect you can count on one hand (and more likely, zero hands). Blender, for example, does a terrible job even interpreting cutout objects in OBJ files, a common case (see step 9). I doubt they'd ever add per vertex color import support for any file format they read in. But, I'm interested to hear if they do - Blender is (by far, I believe) the main DCC app used with Mineways exports.

Is it just mean, or is C# easier to learn than JavaScript or even PHP?
It's not the type system you're complaining about, though. It takes a bit of work but you can write types that include units information with no loss of performance.
-
I'm a beginner making a library for unit conversion, contributions are welcome
I recommend using this as reference https://github.com/mpusz/units it probably solves the same or similar problem.
-
Why is this piece of code compiling with char as c-tor argument?
Yep. And there are some libraries to provide strong-type int, depending on what you need: type_safe or even units.
-
C++'s smaller cleaner language
Indeed you cannot. Then again, you couldn't write a library like fmtlib in C in the first place. I mean why do you complain about C++ features which enable you to write libraries you otherwise couldn't? How would you expect to implement equivalent libraries to EVE or mp-units in C alone?

I got curious about units of measure in programming languages so I recreated xkcd/687.
How does it compare with https://github.com/mpusz/units ?

C++ for Mathematicians
I don't have a book to recommend, but I have a fantastic library: https://github.com/mpusz/units
- Cheatsheet for the C++ core guidelines (philosophy)
- Compile-time C++ library for compile-time dimensional analysis, units/quantities
-
Please Put Units in Names
Good C++ library for that topic is [0]. You can even go further and combine with something like [1] which is super helpful for kalman filters and other stuff where you have heterogeneous units in one vector.

This seems to be on a progress to standardisation for c++23/26: https://github.com/mpusz/units
