you, we are making available a page of Homework Hints,

COPYING LECTURE PROGRAMS:
If you would like to copy any of the lecture examples, they are available to
you through your FAS account. Log into your account, change into the directory
where you'd like the program to be, and then type this command:
cp ~libe50a/unit2/programName.java
.
Be sure you include the period at the end, after a blank space or two - this
will copy the file and keep the same filename. You should change 'programName'
to whatever program you wish to copy. You may also get the sample programs that
Dr. Leitner writes in lecture using this command.
COLUMBUS DAY: Monday October 12th is Columbus Day - there will NOT be
a lecture on that day. However, the Monday evening section WILL meet at its usual
time and place.
MIDTERM: Our midterm exam will be held on Monday October 26th during
the first hour of class. If you are in the 6-state New England area, you
are expected to come to campus to take the exam. If you are outside this area,
you will need to schedule a proctored exam. Please see the information on the Extension
School website, and set up your proctor during the coming week.
HOMEWORK 2 CORRECTION: In Part D, the Babysitter problem states
that it is required for graduate credit students. It is one of the programs you

in Applications / Utilities / Terminal), and the command is: ssh
username@nice.harvard.edu Enter your password when asked.
On the PC you should download Secure CRT from the FAS
Downloads page. Click Downloads in the top menu and then log in with your

If you change your mind, you may run the program again to make a change. You
will need to know your section in order to submit your Scratch homework!

WELCOME! We hope you'll join us for the Fall semester of
CSCI E-50a! We assume that you have no prior programming experience,
but that you are comfortable doing basic things on a computer
(e-mail, web surfing, writing a letter, etc.). Come explore a
new world with us!
LECTURES: Lectures will begin on Monday, August 31st!! We
will be meeting this year in Maxwell
Dworkin, in Room G-115.
This year our lectures will be "live-streamed" - this means
that you can log on from home and watch them live as they are being
given. To do this, at class time, open your browser window and
go to: http://classroom.dce.harvard.edu.
You will see a list of classes being given with live-streaming,
and ours is third on the list. Click the class name, and it will
take you to a page where you can join the session. If it displays
a message that no videos are available, the page should automatically
refresh so that when we begin, you will see a button there labeled "Join".
Click that button to watch live. |
