The ‘Doom’ in the title refers to the original computer video game released by the folks at iD software. 25 years ago, on December 10th, DOOM.zip was first published on the University of Wisconsin FTP server in December 1993. When the upload was complete, 10,000 people attempted to download the game at once, crashing the university's network. That game was the true push to the next generation of FPS games, moving away from fun to more darker genres. Every video game in use today has inherited or was inspired in some way to the original Doom.
I myself came across the game only five years later, given the serious lack of internet connectivity in India. People had to share the first episode of the shareware offline on floppy disks , and magazine CDs. The programmer in me was instantly hooked, more by the complex worlds created by the code on a 2d screen, than the actual game play. I knew immediately, I wanted to get into 3d graphics programming, and join the team of cutting edge , microprocessor system programming.
Years later, well, I am no-where in that area, although I do code. I now work in boring enterprise computing, using a fraction of my brainpower I used during my assembly language days in school. I did end up creating a 3d engine, using sectors for maps and perspective texture mapping, but I could not start a career into that area.
John Carmack is a computing god. And Doom is just one of the ways he pushed computing power of the 90s to its limits. Those days of efficient, system programming is long gone, and modern programmers don’t care about using as little memory as possible. But if you are interested, you can read about the source code of Doom in a new black book.
Its only a matter of years before Doom will end up in the museum of computing history.
