Homework for this class will be collected electronically by the turnin system. You reach that system on the web by pointing your browser to http://turnin.cs.umb.edu/.

• User names and passwords

  In order to use the system you need a User name and a password. We have assigned you a user name, constructed from the first six characters of your last name followed by characters from your first name to make up a String of length at most eight. Here are some examples:

  	Full name	turnin User name
  	Kent, Clark	kentclar
  	Kennedy, John	kennedjo
  	Liu, Wei	liuwei
  

  Note that turnin user names are all lower case.

  All students start out with the same turnin password, which your instructor will tell you in class.

  Your first task is to change your password. Choose a good one. That's difficult, because there are conflicting requirements. A password should be easy to remember and hard to guess. Your password should

  • be at least eight characters long,

  • contain some upper case characters, some lower case characters and some characters that aren't letters or digits,

  • not be constructed in an obvious way from your name, or from any other easily available personal information, or from any words in any dictionary.

  You should not use the same password for multiple systems (for example, at multiple ecommerce sites) nor should you write down all your passwords in some obvious semipublic place.

  Never tell anyone your password. Not your friend. Not your partner. Not your instructor. Not your dog.

  Most people do not follow all these sensible guidelines. Don't be like most people.

  To change your password, connect to the turnin system and click on the section you attend. Enter your turnin user name and current password in the fields provided. Then follow instructions. You will be asked to enter your new password twice, just to prove (the first time) that you remember it. Do type it twice, don't just cut and paste.

• If you forget your password

  Tell your instructor. He or she will arrange to have a new one assigned to you (that may take a day or two). Then change that one, and remember it this time.

• Submitting work.

  To turn in work for an assignment, log in to the correct section with your user name and password. (The turnin system will not permit you to log in to the wrong section.)

  Do not log in to the Turnin demo, even if the turnin system will let you.

  Do not log in to cs119, even if you are in cs119, even if the turnin system will let you.

  Enter the folder in which your work should go. For homework 1 that's hw1.

  Indicate how many files you will submit. For cs110 hw1 that will be two if you are submitting both required files at the same time: memo.txt and Bank.java.

  The system will prompt you to browse for the files on your computer.

  After your submission is complete you will see a confirmation page in you browser, and the system will send you confirming email as well.\

  CLOSE THE BROSWER . If you just visit other pages then the next time you (or anyone else) returns to turnin you will still be logged in. That's unfortunate - we are working on fixing it.

• Acceptable file types

  The grading software accepts only plain ascii text. Do not submit MSWord docs, or class files, or images, or web pages. (Even if the turnin system accepts them, the software that needs to read them will choke later on.)

• Resubmission

  You may submit a revised version of any file at any time up until the due date for the assignment. The new version will replace the old one.

• Frequently asked questions

  The FAQ link on the turnin system page is the one that came with the system when we took it (with permission, of course) from its original authors. The information there is not necessarily correct for UMass-Boston. Some day we will get around to rewriting it.
