I'm learning quite a bit about the Linux graphics stack recently. I started reading about openGL and cairo and how they work with drivers, the X Window System, the kernel and ultimately the GPU(allthisbriefly). Today I was reading about X11 because I wanted to learn how to create a window with compiled C code and eventually from there start messing with graphics some how. So I spent all day learning how X clients interact with the X server using the X11 protocol.
(this sparked ideas on how I could finally make use of that raspberry pi over the network for fun creating windows and such with xorg\x11.. and maybe from there ask my bud who lives in a different state if I could try putting some windows up on a test machine or somethin over the internet) Anyways, i'm excited...
I want to see who can stupefy me the most. Show me the lowest level code you yourself have written for a game. :)
