All electronic submissions must be made using the procedure that will be outlined in class and here later. Electronic submissions in all other forms, such as email or physical media, will be discarded and receive no credit.
Illegible, hard to read, or otherwise messy submissions, whether handwritten on typed, are likely to be returned without grading, for zero credit.
Fallback procedure If (and only if) there are unexpected problems and you are unable to submit your work as above, then you should save your file on your own computer (with some backups), compute its MD5 checksum using the md5sum utility on Unix-like systems (or other similar tools), and submit the file name, time stamp, and MD5 checksum (only, not the file itself) by email with a suitable Subject header.
