The mainframe was an IBM 370 with VM and a variety of guest operating systems on top of it, including CMS and several batch systems. The computer was a mainframe that lived out near the airport, and there were a bunch of punch-card/printer computer centers around campus that needed operators to feed them. Phil had a job one year as a computer operator. com/ IdaSurface.Back when I was in college, and we had to walk uphill both ways in the snow to get to the punch-card computer center, my freshman roommate was a ham radio operator, and was friends with another ham, Phil Karn, KA9Q, who you might remember from TCP/IP on DOS and other projects.

Surfaces, which are doubly covered and therefore appear to be an immersed Topologically, all surfaces are Klein bottles, even the Roman and Boy Kepler's laws derived from Newtonian gravitation.Ī 3D immersion of a Klein bottle that smoothly deforms between theĮtruscan Venus surface, the Roman surface, the Boy surface, and the Isaac Newton's Principia Mathematica was published in 1687, and proved that For displays with multiple screens, XScreenSaver will manage all screens on the display simultaniously.
