cheatsheets

stuff i look up often, written down so i stop googling it.

• x86-64 for registers, the calling convention, and instructions
• interrupts for x86 interrupt calls, my slice of ralf brown's list
• gdb & lldb for the same debugging moves in both
• graphics for the pipeline, rasterization, raycasting, bsp, and raytracing
• math for matrix calculus, index identities, gaussian integrals, and residues
• quantum mechanics for angular momentum, perturbation theory, and operator identities
