Homeworks will generally be due every Monday by noon. Late homeworks will not be accepted. Be sure to include the names and emails of all your group members.
Code assignments must be submitted electronically. See below for details. Written assignments must also be submitted electronically (in ascii, ps or pdf form). We strongly encourage you to typeset your assignments using LaTeX.
To electronically submit homework, copy the Postscript or PDF file containing your solution to your SEAS Eniac account using, for example, scp:
% scp main.pdf eniac-l.seas.upenn.edu: Password: ****** %Then connect via ssh to eniac-l.seas.upenn.edu and use the cis500submit command to submit your file for grading:
% ~cis500/bin/cis500submit hw1 main.pdf Submission successful. %Your files must be world-readable in order for them to be submitted. If you do not see "Submission successful" printed out, then we do not have a submission from you, and any previous submissions for that assignment were likely lost. For example, both "Submission FAILED" and "Cannot submit ..." both indicate an unsuccessful attempt at submission.
cis500submit will accept multiple files as input and can be run multiple times before the deadline. IMPORTANT: each time you run cis500submit, it overwrites your previous submission for that assignment. If you need to submit multiple files, submit them all at once.
One final note: cis500submit does not follow symbolic links. It's simplest to specify the actual file on the command line.
