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.

Show HN: C-ocoa, Write iOS/macOS apps in any language, with a generated C API
Interesting project, though I'd rather just use Obj-C. I guess if you wanna use it in something like JavaScript or Lua it'd make sense to have C as a bindi g layer.

Interesting, I've been using a similar project for Nim lately: https://github.com/treeform/windy
It's surprising how simple Obj-C interaction is compared to Java JNI or something. Here's the Obj-C interop for Windy:

How to detect and even save key presses
I used https://github.com/treeform/windy in my text editor. It's a pure Nim library like SDL. For separate keypresses I used a state machine where every keypress advances the state and when it reaches an end state the action performed. Works pretty well ^

Simple Gamepad Support
I made it because I really like pixie/boxy/windy combo, but there is no gamepad support built-in.

Is Fidget usable for implementation of 3D rendering?
The author Fidget actually has a number of other great libraries that are part of the rendering stack. Notably, Pixie for text and shape rendering in 2D, Boxy for rendering textures to the GPU via opengl, and then Windy for an OS window context and user events, and a number of other libraries related to 3D rendering.

Nitro: A fast, lightweight 3MB inference server with OpenAI-Compatible API
My understanding is the proliferation of “XYZ-cpp” AI frameworks is due to the c++ support in Apple’s gpu library ‘Metal’, and the popularity of apple silicon for inference (and there are a few technical reasons for this): https://developer.apple.com/metal/cpp/

Show HN: C-ocoa, Write iOS/macOS apps in any language, with a generated C API
This is basically also what the "official" C++ API for Metal does (https://developer.apple.com/metal/cpp/), it's an automatically generated bindings wrapper which calls into ObjC runtime functions.
I also dabbled a bit with this idea by parsing clang AST-dumps of macOS system headers:
https://github.com/floooh/objc-ast-experiments
Unfortunately this is very brittle, and also broke on ARM CPUs, I guess the shim code needs some ABI adjustments (famously, objc_msgSend has multiple "ABI shapes": https://www.mikeash.com/pyblog/objc_msgsends-new-prototype.h...).

- Opinion for graphic api's?

A brief interview with Tcl creator John Ousterhout
It doesn't matter if the project driven by Microsoft or not, the cat (of automatically generated language bindings) is out of the bag. E.g. Zig is using the same approach without being an official MS project: https://github.com/marlersoft/zigwin32, and Apple has an automatically generated C++ API for Metal (https://developer.apple.com/metal/cpp/).
In the future, the question won't be "what language do I need to learn to code on this platform", but instead "are there language bindings for my favourite language".
- Cross platform low level graphics API suitable for game development?

GCC now includes Modula-2 and Rust. Do they work on OpenBSD?
this? https://developer.apple.com/metal/cpp/
Doesn't it just use objc/runtime.h and if anything is missing you can just add your custom api calls?

A learning path for Vulkan that focuses on concepts?
Metal has C++ bindings (which cover a full app lifecycle so you don’t have to touch Objective-C/Swift at all) but they’re based on the Objective-C memory model. There are some helper structs mimicking shared pointers, but you’ll still need to understand the basics of how an autorelease pool is used to avoid memory leaks and/or bad access crashes.

NimForUE - Nim plugin for UE5 with native performance, hot reloading and full interop that sits between C++ and Blueprints. This allows you to do common UE workflows like for example to extend any UE class in Nim and extending it again in Blueprint if you wish so without restarting the editor. The final aim is to be able to do in Nim what you can do in C++
