Wed Apr 26 8:47 pm: Please read the following message carefully. Project #7 is an open project. You should not lean too much on other students for this project otherwise you will not learn what the project is intended to teach, and this will hurt you on the final. Remember, an open project does not mean you can share code. Here is the policy for open projects (which is already available in the class syllabus):
For open homeworks:
- You should try as much as possible to complete the homework by yourself.
- Assistance can be provided by teaching assistants (TAs), instructors, students in the course or other individuals.
- You must not submit another student's code (all or in part) as yours.

Fri Apr 21 2:33 pm: Video: Implementing a Heap - This video illustrates the process a programmer (Prof. Bill Pugh in this case) goes through while implementing code. The implementation presented corresponds to a heap implementation. This video was filmed in Dr. Bill Pugh's lecture, and it is the first part of a two-part video. Keep in mind that in this video some bugs might be present in the implementation as the testing phase has not been completed yet.

Mon Mar 6, 9:02 am: ITunes Jr Demo Day this Wednesday March 8 in lab. This Wednesday (March 8) all students that want to show their ITunes Jr GUI to the class can do so in lab. You are not required to demo your GUI on Wednesday, and those providing a demo of the ITunes Jr will not receive any credit or extra credit. Here are the general guidelines for this demo day:
-
A student will stand in front of the class and show their GUI on the main projector.
-
The student will show the code that implements the GUI to the class.
-
Students in the class may provide feedback (positive criticism is very important here) about the code.
-
Although students can see other students' code, no student should ask for another student's code or receive any such code.
-
Each student will have about 5 minutes to show their GUI.
-
To show your code you can use your own laptop or one of the Lab Macs.
-
Please don't be shy about showing your GUI/code. After all, one day you will have a boss and she/he will look at your code :).
-
If you want to improve your GUI for the demo that is fine.

Thu Feb 16, 10:08 am: If for some reason you realize you need to make major changes to the UML diagram you submitted on Tuesday then follow these steps:
-
Create a text file named "reasonsForUMLChange.txt" and explain why you needed to updated/change your UML diagram and what are the changes.
-
Create a zip file with the reasonsForUMLChange.txt file and the new UML diagram.
-
Upload the zip file using the Submit Server P2-UML Design entry by Friday Feb 17 at 6:00 pm.
Keep in mind that you will lose points for implementing a project that does not corresponds to the UML diagram you submitted on Tuesday. The above steps will prevent you from losing a significant number of points. Remember, you will need to complete the above steps only if major major changes are required in your UML diagram.
