Windows Earlier today, OSNews ran a story on a presentation held by Microsoft's Eric Traut, the man responsible for the 200 or so kernel and virtualisation engineers working at the company. Eric Traut is also the man who wrote the binary translation engine for in the earlier PowerPC versions of VirtualPC (interestingly, this engine is now used to run XBox 1 [x86] games on the XBox 360 [PowerPC]) - in other words, he knows what he is talking about when it comes to kernel engineering and virtualisation. His presentation was a very interesting thing to watch, and it offered a little bit more insight into Windows 7, the codename for the successor to Windows Vista, planned for 2010.

"Windows Vista is Microsoft's OS9. It's done, it's used used up, there's no more stretch in the elastics, as we Dutch say. It's time to move on, and make a viable plan for the future - and I don't see how Microsoft can maintain its relevancy by building atop Vista."

Yes, exactly like OS9 - a 64-bit, preemptive multitasking, hardware graphics accelerated OS9 with virtual memory.

Not literally, of course. Don't you grasp the concept of the analogy?

I would send this privately, but mine's preemptive. 2000Hz swap rate, actually. It has the OPTION of turning-off preemption on a task-by-task basis. Other operating systems prevent potentially abusive features, like applications turning-off interrupts (not same as turing-off preemption). Mine allows both.

True, mine does not have hardware graphics acceleration -- couldn't bring myself to look at Linux code and steal it.

I worked for a certain nameless monopoly event-ticket-selling company (who probably wasn't the one which crashed today selling world series tickets ) that had their own operating system and learned about processes voluntarily yielding the CPU before preemption. They had a propriatary VAX operating system and I'm pretty sure it once ran without preemption, since all code was controlled by the company and could be guarenteed not to abuse the privilege. In addition to some work on the operating system, I wrote business report applications and had to include commands to "swap-out" periodically so it didn't hog the CPU and ruin other user's responsiveness.

Yeah sure - apples are just like oranges.
