perceptronCobol VS SDL

I used to work in a bank with people that came from mainframes. They use to talk about Cobol and how it was a well paid job, cause of the lack of programmers.

As a way of learning the language I end up writing a perceptron in it [1]. It was a fun exercise.

I don't know if this could be considered "learning" in the sense that you mean, but I chose code that I wrote in a familiar language and re-wrote it in Cobol. It was fun and I end up learning a lot.

Correct. It's explained here:

XWayland has special hooks into the compositors that normal wayland clients don't get.

Found about this through the release of SDL 3: https://github.com/libsdl-org/SDL/blob/main/build-scripts/SD...

https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_events.h

If that app ran in a 640x480 mode, memory accesses would be just as fast as the VGA applications 25 years ago, correct?

I think there's a lot more going on than that. Here's SDL's current pixel access code:

We use the code examples throughout the article. The ellipsis characters "...." in the code were added by the author of the article. You can find the source files on the official GitHub of libsdl. In addition, each fragment has a reference to a specific area in the code. By the time this article is published, many errors will have already been fixed thanks to the issues we opened (for example, here and there). However, the links in the examples point exactly to the code you see in this article. Not only do we enjoy teasing developers but we also like making their projects a little bit better!

It's not that difficult, I recently started learning to use graphics APIs myself. OpenGL is for linux, etc., directx for windows and vulkan for all platforms. I read through a bunch of forums yesterday and decided to go for vulkan (here is a link to the sdk) for my next small projects because it can run on all platforms. I would recommend to watch a basic tutorial series (like this one) for the graphics api itself to get an understanding of whats going on. And on top of that I use SDL2 for eventhandling and ImGui for the graphical user interface. Here is a link to a guide for setting up vulkan on your platform in case you would go for it.

If I have the the skills and expertise: I could theoretically build a simple input remapper none using SDL (Steam Input relies on it) or JoyShockLibrary as a way to handle much wider Controller Support (otherwise: it would've been far more difficult to get Input API working across major Controller Types without documentation or reverse engineering).
