CS212 Problem Sets
Submitting directly through email

The email address for homework submission is "cs212+hw".

Each student (or a pair of students) has a file stored in the CS212 account for each problem set. You can submit a file, delete it and so on. In order to be able to use this system you must get a user id (UID) which is a three digit-number will be given to you by mail. Everyone should request a number. You should only mail using your Cornell account.

Follow these submission instructions exactly, in case of a mistake, you will get this text as a reply:

• To submit a file, mail it to "cs212+hw@cs.cornell.edu".
• The subject line should be the command, its general syntax is: "UIDS COMMAND PS"
• The UIDS field should have the form of UID or UID-UID and so on (usually, two people per problem is allowed - do not specify more unless authorized). Do not put spaces between UIDs.
• Each of these UID should be one your own three-digit number, if you don't have one, or if you forgot yours, mail the course staff (UID's are given manually).
• Each UID is registered with some email address, so always mail from the same place (using your Cornell netid). Do not try to use random numbers.
• All UIDS that are submitted should be unique, you cannot submit a file with a group of UIDs that you are not registered with one of them.
• If you submit a new file, there shouldn't be any other file with one of the UIDs in this file.
• The COMMAND field is one of "submit", "check" or "delete". The first one is used to submit your file, the second to verify that it is there, and the third will delete the stored file so you can submit another version. One last command is "overwrite" which is the same as submit but if a copy exists already, it will be deleted first.
• The PS field should name a valid problem set - you will not be able to submit anything to problem sets that are not yet available, or that are over. The check command will not work either. These names will usually be "ps#" where "#" is replaced with the problem set number.
• On every server query you will get a message-id as part of the response, you can use these numbers as references in case of problems.
• All mail messages are saved in a backup space, so problems can always be resolved, and it will be much easier if you save the message-ids.
• Last note: please DO NOT play with the system, try to overload it or to break it - we do have that backup and any attempt to do one of these things will not be tolerated.
