[LON-CAPA-admin] L-C log rotation

[Gerd Kortemeyer]

Hi Peter,

The dog ate my homework ...

Yes, there is a student activity log, logging all of his/her  
activities, in the student's home directory. It doesn't rotate.

The course coordinator can view it from email messages or from the  
student's home screen.

Smart practice that stops all of this: don't accept any "the computer  
ate my homework" from any student who cannot present a valid receipt  
number for that problems. Students need to write down the receipt  
numbers - if they don't, their fault. Those are unique algorithmic  
proof that they solved the homework, and does not depend on any data  
stored on the server. You can validate those numbers from the PGRD  
screen.

Proof-positive is much easier than proof-negative.

BTW, a frequent scenario is the following: room mate or study partner  
left LON-CAPA logged in. Student A walks up to open terminal of  
student B and solves B's homework instead of their own. B is  
convinced that they did the homework, A naturally does not complain.  
Receipts would also detect this situation.

- Gerd.
