Some very interesting Linux anecdotes on this website, stories from the very early days of the Linux operating system, before we had the easy to install Linux distributions we use today. Apparently Linus Torvalds is/was a Doom fan and spent a lot of time playing that game as well as Prince of Persia. I guess many, many people have played that incredible game over the years. I have played around with the old linuxxdoom source code and managed to run that on a 256 color X11 session. But the sdldoom port is easier to get running on a modern PC. Nowadays there are source ports like Zdoom that can be compiled on Linux. I am reading through this book: The Ultramarines Omnibus by Graham McNeill, a story that follows a team of Warhammer 40K Ultramarines in their struggle against many evil foes and the struggles and glorious battles they fight.
I recommend this book to any fan of the Warhammer 40K universe and even though I have never played the tabletop game or anything, I find this a riveting read with the weapons and history of the Emperors finest soldiers described with amazing detail. If you are a fan of the Warhammer universe then definitely grab a copy of this book, it is well worth the read.
