The FINAL EXAM will be Thursday, March 22 from 8:00-11:00 in the usual classroom.
Bring your official UCSC picture ID with you to the exam and be prepared to show it upon submitting your exam.

3/13/12 - Assignment 7 is now posted. Due to the short time left in the quarter, I have made it optional and EXTRA CREDIT. It is due any time before 5:00 pm on the day of the Final Exam (Thursday, March 22).

3/8/12 - More example code -- our character counting program. It takes as input, one the command line, the name of a file to count the alphabetic characters in. Run it like this:
    java CharCount book.txt
(assuming you want to count the characters in a file named book.txt).
You may copy and modify code from this example, for example the file reading code, for use in your cryptography program.

2/27/12 - As we approach the end of the term, I am adding another set of office hours.

My office hours for the rest of the quarter are:
• Mondays 3:30-5:00
• Wednesdays 10:30-12:00
• Fridays 11-1

2/27/12 - More program examples:

2/27/12 - My office hours will be 1/2 hour shorter today, from 3:30 to 4:30 (instead of 5:00), due to a medical appointment.

2/22/12 - Midterm 2 will be on Friday, March 2.

2/15/12 - Some problems we will work on Friday: Ch. 4, Exercises 8, 15, and 17.

2/13/12 - I have decided to make assignment 5 a two-week assignment.

1. Create the array, initialize it, and print it out
2. Create a mechanism for updating the array based on a single rule, then update the array once and print it out
3. Create a loop that applies the rule over and over, printing out the array after each step
4. Generalize it to work with any rule
5. Simplify and refine the implementation

2/13/12 - Some program examples:

2/1/12 - Midterm 1 today.

Here is a link to the current version of Javadoc

1/25/12 - Interesting talk today: The Chief Information Officer of the New York Stock Exchange will be talking today at 1:00 in E2-180 about some of the real-time computing needs of the stock exchange. I encourage all of you to attend, if you are free at that time. It should be very interesting and highlights some of the impact of our work as Computer Scientists in the real world.

1/23/12 - As explained in class on Friday, we will use eCommons for all homework assignments and submissions. The assignments will be posted there and all submissions must be via eCommons.

All assignments starting with #1 will be graded and all must be turned in before the lab following the one in which the assignment is discussed. (The due date posted on eCommons is the latest possible, but your actual due date depends upon which lab you are registered for).

1/18/12 - To log into the Unversity UNIX systems from your own computer, you need an ssh program. To get putty, a good ssh program for the PC, click here. To use it, enter "unix.ucsc.edu" in the Host Name box, then click on the Open button. Then log in with your username and CruzId Blue password. Now you can start entering unix commands to run on the University's unix systems. Any files you create will be in your Unix home directory on the University systems.
