As per your email, a 0 means that the TAs did not receive a homework submission from you. A blank means that you did not exactly follow the directions and the TAs could not figure out how to initiallize your server. If you have a blank, you should have received an earlier email from Hameed asking you to come in and demo your assignment. The fact that the blank remains indicates that this demo has not been performed. If you still need to demo, Hameed should accommodate your schedule at this point in the semester. (In fact, you should insist on it and cc: me if he is having trouble finding the time)

If you got a number grade, realize that this is out of 200 points. If you are surprised at your grade, here are the procedures and exact commands I asked the TAs to use, and here are the exact point values which were deducted for various offenses.

There were three levels of testing: a full credit test using FCacm and FCpws,
a partial credit test using P1acm, and P1pws, and
I initially planned to offer a consolation prize using the exact files given on the web page.
In the end, Seung Wook took even more pity on you and cleaned those files up as explained here, resulting in Wacm and Wpws.

If you think your grade is incorrect please contact the TAs (and cc: me) with your concerns ASAP. I apologize once again for the way in which this homework was handled. I am in charge of the class and the ultimate responsibility rests with me. I repeat my promise that you will not be penalized by not having a chance to redress an incorrect grade, but it will be easier on all of us if you help me out by trying to resolve any conflicts ASAP
