Some people have asked for an extension for the project. (Based on the mails I am getting, it is also possible that there is a bit of "behind the scenes organization" going on--since the frequency of mails has increased in the last couple of hours).
In extending deadlines at the last minute, my concern always is for those students who probably re-organized their lives to keep up with the announced deadline. To make sure that these people do not feel penalized, I will do the following: You can submit the project on Thursday with a flat 20% late penalty (this may look steep compared to zero penalty, but you should compare it to the "infinite" penalty implicit in the concept of "deadline" and feel blessed ;-).
(If it is indeed the case that the whole class needs the two extra days, then all of you get 20% penalty--and the idf of the penalty will be zero.. )
Please note that projects are due at the *beginning* of the class; resist the temptation to skip class and give the project at the end of the day..
ps: As I mentioned, you will still get partial credit for the earlier parts if you get all parts working by the final deadline.
