Yello! I have been busy searching through the archives of my yahoo group which I started way back in 2003. And guess what? It has a wealth of information. It is quite amazing to see how I have evolved in my art of writing and thinking. Feels a little bit nostalgic to start talking about MS DOS, Windows, etc. Now that I have been almost exclusively working with Linux on the system level and have kept myself confined to application layer on Windows, it really is fun to go back and look at my article on Windows System Programming from 2003. I talk about a lot of stuff including message queues, context switching, semaphores and mutexes, BHOs, TSRs, etc. I doubt if people use them application layer programming anymore (atleast I don’t). It is long and quite interesting. The unedited article follows.
