General Information:

Previous Semesters: Fall 2010 Fall 2009 Fall 2008 Fall 2007 Fall 2006 Spring 2006 Fall 2004 Fall 2003 Fall 2002 Fall 2001 Fall 2000


Class Policies and Grading

How Grades Will Be Computed. Final grades will be calculated based on the following weighting scheme. It is possible that the weighting formula may be adjusted as the semester progresses. Any such changes will be announced to the class:

Undergrads
Grads
CategoryWeight
Homework 112%
Homework 212%
Homework 312%
Homework 412%
Homework 512%
Exam #120%
Exam #220%
CategoryWeight
Homework 110%
Homework 210%
Project40%
Exam #120%
Exam #220%

For final letter grades, an overall average of 90-100 will result in an A, between 80-89 a B, between 70-79 a C, between 60-69 a D.

Students taking the class pass/fail must receive a B or better to pass. Students auditing the class will not be required to complete homework or exams.

Homeworks. Details on the requirements for successfully completing the homeworks will be given in the assignment on the Web. The homework is due by 11:55PM on the announced due date. The grade for a late homework assignment will be marked down 10% for each day it is late, maximum of three days (homework turned in more than three days late will receive a zero).

The work is expected to be completed by individuals and not in collaboration with others.

Exams. Exams will be based on assigned readings, lectures, and homework.

I expect all students to show up for exams and submit homeworks in a timely manner. No make-up exams will be given without written notice of an emergency (doctor's notice if in the hospital, for example), and IN ADVANCE if possible.

Project. Graduate students in the class will be expected to complete a multi-part project during the second half of the course. The project structure will be presented in class. The project consists of separate milestones, including a project proposal, implementation, demo, and final writeup.

Other Policies. A good portion of the learning in any upper level or graduate class comes from intelligent discussion during the class. If you don't attend class, you cannot participate, and your performance may reflect that. I expect that each student will make an effort to attend all lectures and contribute constructively to the discussion.

Students are expected to follow Georgia Tech's code of academic conduct. I am required to forward all suspected cases of academic misconduct to the Dean of Students, where they will be pursued to resolution. This is a very unpleasant process for all involved, so please do not put us in this situation.


Reading Materials

There is no required textbook for this class.

However, as we will be doing programming assignments using the Java Swing GUI toolkit, understanding the nuts and bolts of Swing programming may be useful. Thus, I'm recommending Java Swing, Second Edition (Loy, Eckstein, Wood, Elliot, and Cole; O'Reilly Press) as a good book on Swing with broad coverage of the toolkit.

If you don't want/need the book, you still may want to take a look at some of the links and documents in the Resources section of this page.

Another good book (also not required, but useful if you want to do fancy Swing stuff either in class or later on your own) is Swing Hacks (Marinacci and Adamson; O'Reilly Press). Lots of nifty tricks, plus it's written by a Georgia Tech alum. Another, more recent book in a similar vein that I haven't yet checked out in as much detail is Filthy Rich Clients by Haase and Guy.

Additional required readings for each class will be provided electronically and posted on the course syllabus. In addition, some supplemental readings will be provided. These readings will not be required but may prove useful as background material for students.


Resources, Documents, and Software

We will be using Java Standard Edition, version 6 for this class. Please be sure your code works with this version. Note: at the time of this class, version 7 is available but very new and has some reported bugs. Please do not use Java 7 for the homeworks!
