Dave builds the World's Smallest Windows application live in x86 assembly using only a text editor and the command line to assemble the program using the Microsoft MASM assembler. Whether you're a professional programmer or just curious about how assembly language works, what makes it different from machine language, and why it can be faster and smaller than C you won't want to miss it! Take your Windows Programming to the next level. Or the previous level, depending on how you look at it!

Thanks for the recent shoutout on the podcast! I realize you can make a much smaller app by simply calling MessageBox, but that's why I outlined what I deem to be the "minimum functionality". SonicMouse has come the closest so far at 1776!
