Software

We will use the Racket environment extensively. DrRacket, the major component of Racket, will be used to develop code, debug, and submit homeworks. CCS computers have an updated version installed (available on both Unix and Windows). To use it on your own machine, get it from the Racket website. Binary installers exist for all major operating systems, and the course work will be platform independent.

Racket has a system for distributing software bundles that will be used to get a course-specific plugin. This packages both specific functionality for each homework, and an integrated tool for homework submissions. Once you have Racket installed, download the plugin package, and use the “Setup PLT” application to install it. You can also use “Install .plt File” in the File menu, and enter the URL for the plugin.

Note: The handin server uses a dedicated port for communication. You need to work from a network that does not restrict this port — for example, if you use Northeastern’s ‘NUwave-guest’ network, then you will not be able to connect to the server. ‘NUwave’ (which requires you to authenticate through myNEU) does not have this restriction.

Additional software may be used later in the course.


Piazza Group

There is a piazza group for this course at Piazza.com. The piazza group is the main medium for discussions, questions, announcements etc. You should use it if you have any questions, so others can benefit from the discussion as well. If you want to ask a question that involves showing your solution code, make sure that you choose the “private” option. Do not to post any homework code on the piazza group without using the “private” option. Direct emails to the course staff should be your last resort. Consult the Email and Piazza Group Policies handout for further details about piazza group posts and emails.

Note that you do not need to request to be subscribed to the mailing list — you will get added after you register with the submission server.


IRC

IRC, or “Internet Relay Chat” is a text-based chat protocol where people can join channels on IRC servers and communicate. IRC is sometimes refered to as “interactive notepad”. The major benefit of using IRC is real-time conversations with fellow class members as well as course staff.

If you have a CCIS account, you are almost ready to start using IRC. The following will describe a basic configuration, as described by jmendel (aka John Mendelewski). Feel free to set up your client as you wish.

Read up on these commands before you start experimenting. Google is your friend.

Finally, IRC is a valuable resource: don’t abuse it! Specifically, you should not post any source code, and you should try to read homework texts thoroughly before you ask questions. This applies for both channels.


On-line books and other materials

There are lots of Racket and Scheme books on-line, a few good ones are:

You can also find some good on-line courses: In addition, there are lots of additional Scheme-related references at Schemers.org.
