RAT 3 results
The average score was 43.5 and the standard deviation was 12.53. The grades were no where near a normal distribution. To scale things a bit I made everything above the average of 43.5 at least a B and everything below, a C or lower--that is 43.5 is equal to 80%. This adjustment is what you see factored into the grade spreadsheet.

Task
Install virtualization software (for example, Sun's Virtual Box) on your laptop. Install an operating system (no Microsoft OS, no Linux) as a virtual machine. You will demo the virtual machine and talk about how the kernel differs from LInux. Deadline for signing up for this task is Thursday 5 November. Multiple people working on the same OS must coordinate their talks to cover different aspects of the kernel.
Possible OSs
- Open Solaris
- Mac OSX (may not be legal)
- Syllable Desktop
- Haiku
- Symbian Microkernel
Lab 2 (implementing a page table) posted
This lab is due 14 November.
Thread Lab
What is that last column on the grade sheet?
The penultimate column is a bit misleading because of the huge amount of extra credit people have. That column divides your current score (incl. extra credit) by what you could have earned so far. So it puts too much weight on the extra credit. The new last column divides your current score by the ("possible score so far" score + 6). This also is imperfect but is another indicator of your current status. Your final grade is completely determined by the column "Score".

Discussion
Statistically this looks pretty good. My goal was to have from the mean up to one standard deviation above to be a B and from the mean down one standard deviation to be a C. To make this test match that I added 4 points to everyone's grade. With that addition grades ranged from 66 to 95 with 4 people getting a 90 or higher.
Thread Lab
Now due next Friday the 30th, due to requests. The complete lab as written is due then.
Lab 1
Congratulations to Kurt Koller and Lauren Forney for having an OS that correctly passed all the tests.
Ok, I finished grading lab 1. I will be handing out my comment sheets to you at the next class. The grades for lab 1 are posted. The grades sort of suck. I thought about curving things but then had a better idea. I think it would be better learning experience wise, if I gave people the option of fixing their lab project. This time they can get help from others in the class. I will come up with a scheme that will compensate people adequately for this redo but not at the expense of the people who submitted correct initial labs. Instead of resubmission, I am thinking of in-class demos. We will talk more about this on Tuesday.
