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.

Iterate files/directories/subdirectories in C ?
Thanks for the reply. Yea, I wonder how I would go about implementing an iterative approach tho. I am currently working with the following implementation: https://github.com/tronkko/dirent/blob/master/include/dirent.h

How can you iterate up the directory tree until the program gets to the first?
You can use dirent for both if you include a compatibility shim for windows.

macOS 14.4 causes JVM crashes
Minecraft runs on various Javas.
And there's a known issue with an interaction between minecraft, Java, and the video drivers that crashes out and it can be traced back all the way to here: https://github.com/glfw/glfw/issues/1997
It's not fixed.

Technical Considerations for GUI Toolkits [Discussion]
Window context manager - glfw, sdl
Types of tools for creating a gui (and how those tools approximately work): 1. Utilize the native _graphical interface API_, and depending on the platform, they have specific layers to interface: * Wayland, X11, for Linux * [GDI](https://learn.microsoft.com/en-us/windows/win32/gdi/windows-gdi) for windows * [Quartz](https://en.wikipedia.org/wiki/Quartz\_(graphics\_layer)) for macOS Example - GTK uses [wayland](https://gitlab.gnome.org/GNOME/gtk/-/blob/main/docs/reference/gdk/wayland.md) ([source code](https://gitlab.gnome.org/GNOME/gtk/-/tree/main/gdk/win32)) [X11](https://gitlab.gnome.org/GNOME/gtk/-/blob/main/docs/reference/gdk/x11.md) ([source code](https://gitlab.gnome.org/GNOME/gtk/-/tree/main/gdk/x11)) GDI ([source code](https://gitlab.gnome.org/GNOME/gtk/-/tree/main/gdk/win32)) Quartz ([source code](https://gitlab.gnome.org/GNOME/gtk/-/tree/main/gdk/macos)) [How to use wayland display server](https://bugaevc.gitbooks.io/writing-wayland-clients/content/black-square/the-wayland-client-library.html) (TODO missing "animation" section) 2. Utilize opengl _or other low level graphics api's_ with window context, use GPU to render widgets * Window context manager - [glfw](https://github.com/glfw/glfw), [sdl](https://www.libsdl.org/) * contexts and surfaces, reading input, handling events Example: ImGui, NanoVG, Nuklear, raylib Why? Mainly used for game development, but also good for gui's. _(i haven't seen any examples that uses this method that are used for developing general-use graphical user interfaces.)_

LWJGL = SFML vs Allegro vs SDL vs Ogre vs ???
I'm not familiar with LWJGL, my 5 seconds on their website makes me think you might be looking for something like GLFW https://www.glfw.org/ to handle I/O and window creation/management.

I have spent two whole work days trying to install GLEW
Consider GLFW3 for windowing and GLAD for function loading. I've used this combination myself successfully. Granted, that is "two things" you need, but OTOH it'll work well.

OpenGL (GLFW and GLAD) not linking with cmake
There is a pattern to it which is usable with every GitHub repository. For example, GLFW v3.3.8 can be fetched from: https://github.com/glfw/glfw/archive/refs/tags/3.3.8.tar.gz

Help
That is a static or import library for glfw. You need add the path to the directory where this file is located to the "library directories", see: https://www.learncpp.com/cpp-tutorial/a2-using-libraries-with-visual-studio-2005-express/
