SECTION SIGNUP: Section enrollment is on a first-come, first-served basis
- e'mailing the course account does not get you into a section, nor does choosing
one when you submit your Scratch homework. The only way to enroll in a section
is to run the section program. YOU MUST be in a section to have homework
graded!
To sign up for a section, you will use the FAS username and password that
you created to send your initial e'mail on FAS WebMail. This time, however, you
will connect to FAS using a command line, or terminal, window. On a Mac,
look in the Utilities folder in Applications, and you should see a program named
Terminal. On Linux, you should also find Terminal, or a similar-named
command-line window.
On a PC, you can download SecureCRT from FAS
IT - click the Software Downloads tab on the top menu bar. Enter your Harvard
ID number and PIN when asked. You can then choose SecureCRT and download it.
Harvard has a group license for all enrolled students, which will cover your
use of the software. IF you are running a 64-bit operating system, there is a
link there to a free program called Putty, which you will need to use instead.
Once you have one of these programs, you will connect to nice.harvard.edu -
in SecureCRT, choose Open Connection, and you may find it already listed. If
you type it in yourself, you should use a protocol called SSH2 for the connection
to work. On a Mac or Linux, in Terminal, type the command:
> ssh yourusername@nice.harvard.edu
Replace "yourusername" with your own FAS account username. When asked,
enter your password. After a number of messages from the system, this brings
you to a command prompt, that looks similar to either "ice:~ %" or "username@ice4:~$".
At this prompt, enter the command:
> ~libe50a/bin/section
You should now see a request to enter your name, and then a list of available
sections. Choose the section you wish to join from the list, and you're done.
If you sign up for one section and then want to change your mind, you can run
the program again and select a different section from those available.
SCRATCH HOMEWORK SUBMISSION: AFTER you have signed up for a section, you
may now submit your Scratch Homework on the Scratch page.
You will be asked to authenticate with the username and password given by Dr.
Leitner last night in lecture. You will also need to indicate your section choice
when you do, so that each TA is able to locate the homework submissions for their
students for grading.
SEPTEMBER
9, 2011
SECTION UPDATE: We are still working out sections and have decided that,
since you do not need to submit homework until Sept. 19th, we will give you more
information on sections, show you how to run the section program, and show you
how to submit the Scratch Homework during the lecture on Monday (9/12). Remember,
you may always attend any section you wish to go to!
HOMEWORK 1 QUESTIONS: Several of you have written asking how to do the
two problems with user input, for calculating the temperature and the weight.
Dr. Leitner will cover these topics this coming Monday in lecture, and we will
also do more with them in sections next week.
SEPTEMBER

VIDEOS: The video of this evening's section is now posted and linked at right.
SECTIONS: Note that we've slightly changed the time for the Elluminate
sections below. To attend an Elluminate section, please be sure you have read
through the Elluminate page (linked below), and then use this Elluminate
Link for our online classroom. After enrollment closes and you have signed
up for sections, the link will be moved to the Section page (currently unavailable).

two clips. In the video presentation window, you can click on the course number
(CSCI E-50a - top left corner) to open a window with the website; also, you can
click in the Table of Contents (below the video) to jump to a particular topic
in the lecture.
LABOR DAY (September 5th): Next week Monday is Labor Day here in the US,
so there will NOT be any classes held that day, i.e., no lecture or section.
Sections WILL meet all other days next week, so please plan to attend one of
those sessions.
HOMEWORK 0: We have posted an initial homework to help you get started
with the course, linked below under Lecture Handouts.
Please download a copy - it will be due on Friday Sept. 9th.
HOMEWORK 1: The first homework problem set will be posted later this week,
and will cover Scratch. We will notify you by e'mail when it goes up, and it

SECTIONS: There will NOT be any section meetings this week. Next week
we will have "open sections"
- you may attend any time that works for you. The
times for Open Sections will be posted here later
this week.
Near the end of next week, we will open the Section Program so that you can sign
up for sections. When that happens, information will be posted here on the website.
WEBSITE: As you are looking around the website, there may be some pages
that you cannot access without a login. YOUR HUID WILL NOT work for these
pages. After enrollment is completed, we will tell you how to access them - you
will not need anything on them until after that time.
AUGUST
