you will be able to do your problem sets on your own computer. If you're
running Mac OSX Tiger or Leopard, you'll already have Java 1.6 installed,
which is what you'll need to use to compile programs. You will also
need a programming editor, and there are some listed on this page
under Useful Downloads. There is also info on the Java
page about writing
your Java programs. If you are running Windows, you will need to install
Sun's Java SDK which is linked on the Java page.
Just to clarify Harvard accounts, the Harvard Faculty of Arts and Sciences
originally set up its computer servers to work for two populations - one for
general use, and one for programmers. These went by the hostnames of fas and
ice (for Instructional Computing Environment). Then a few years ago, they added
a cluster of Linux machines for programming, and named that the New Instructional
Computing Environment (nice). Subsequently, ICE was closed. The remaining two
both serve the same group of accounts, so logging into your "FAS" account
can be on either of these servers:
they have different versions of programming software installed and
different capabilities. For our programming, we'll be using nice,
although you can check e-mail or transfer files on either of them.
Once your account is set up, you'll need the software to be able to
connect. If you're on a Mac, you can look in Applications/Utilities/
and find the Terminal program. Open a window, and at the prompt type:
ice1:~ % ssh firstname.lastname@example.org
Replace username with your FAS account name. Type your password when
asked, and you're in.
If you are on a PC, you will need to download some software from Harvard
to make your connection. Go to the FAS
Computing page (http://www.fas-it.fas.harvard.edu/)
and click the link for Software Downloads. After you log in with your
HUID and PIN, you'll be taken to a downloads page. You should get copies
of SecureCRT (for telnet sessions) and SecureFX (for file transfer).
Harvard has a group license covering all students which includes Extension
students. Install this software on your computer. When you start SecureCRT,
it should open a dialog box with a list of Harvard connections, and
allow you to select FAS or NICE. If you need to create the connection,
you can type the hostname into the connection box. Be sure the protocol
is set to SSH2, enter your username, and click Connect. As the connection
is made, you may be asked to save an authentication key, and you should
click Accept and Save. You will then be asked for your password, and
you will be connected to your account.
We do sometimes use FAS e'mail, which you can get to by either going
to http://webmail.fas.harvard.edu in a browser, or by typing 'pine'
at the telnet prompt. I generally point new users to Harvard Computer
PDF for more on how to use your account. To submit homework, we'll
ask you to first upload it to your FAS account, then run a built-in
program named 'submit'. This is described in the link above for submitting
