Show you how to test and debug your Operating System in a very easy way.This article is the second part of my previous article. If you are not yet convinced, try it out and you would see how much fun it is to program Operating Systems. Learning all this would improve the programs you write a lot (even for regular Win32 user interface programming).Learning a lot of new tricks that can help you a lot in other kinds of programming.Learning the hardware of the Computer (CPU architecture, PCI, SATA, cash, Network card, ATA/ATAPI, etc.).Knowing what goes on behind the scenes.Learning the Assembler (Every one would admit, that knowing assembler is a wonderful thing).Learning the executables file format ( helps a lot).In the case of a programmer, the more he knows about the PC and the Operating system, his programs would be more reliable, stronger, and faster, and with less bugs. A programmer is like an astronaut in space, the more he knows about the spaceship he is flying, and how to fix it in case of a problem, it is more likely that he would return safely back to earth.Now, I would list what you will gain from learning how to develop an Operating System: It is not enough to read how an OS works, you have to build one with your own hands. I think that one of the most important ways of being a real professional programmer is to design and build an Operating System.
