Courses
All of the computing work for this course is designed to be performed and evaluated on the Computer Science Department's Linux systems. You may use any computing resources to which you enjoy legitimate access. But it is your sole responsibiliy to hand in your assignments in the form required for the class, and to make sure that they work on the CS Department's Linux systems.
I recommend that you work as much as possible in Ryerson 257. This is an informal work area used by students in several CS courses with substantial UNIX/Linux assignments. You will have the advantage of working with other students in the class, making discussion particularly easy. You will be right outside of my private office in Ryerson 257A, so we can yell at each other conveniently.
Please keep the lab clean. Ryerson 257's lab status is completely informal, and the university does not provide the sort of support appropriate to a public area. So you users must take care of it yourselves.
The Ryerson 257 is currently being reorganized to include office space for about 4 Ph.D. students. The lab is understood to be a slightly noisy area, so you may discuss work freely, but please be considerate of the Ph.D. students' needs for continuous work space. I am trying to get the space organized so that it is clear which areas and computers are reserved and which are up for grabs. All of the Ph.D. students are in the west (inner) half of the room. So the workstations in the east (outer) half are definitely available, and some of those in the west half as well. I welcome any volunteer efforts to improve the organization.
The lab is potentially accessible 24 by 7. But, since there is no formal supervision, access after 6:00 PM and on weekends depends on the presence of someone in the room to open the door. I have no current prospects for arranging reliable supervised access.
PRINTER
to ry257 (export PRINTER=ry257 or
setenv PRINTER ry257, depending on which shell you use),
or provided ry257 as an argument to your print command.
The Computer Science Instructional Computing Laboratories just moved from Ryerson Annex to the Regenstein Library. This lab is supervised formally, and mantains regular hours.
You may work remotely (e.g., from your home PC) on the
Linux stations in Ryerson 257 and Regenstein. You must use
ssh instead of telnet or
rlogin. ssh is more secure, more efficient,
and it provides remote display of X applications in a secure
and efficient way (so you don't have to worry about xhost
or setenv etc.) Each host is addressed by the hostname
given above, followed by .cs.uchicago.edu (e.g.,
union.cs.uchicago.edu).
You will need to use the following software for your homework assignments:
There is a handful of software external to DrScheme that will be used in this class. All required knowledge will be covered in the tutorial sessions offered in Reg. Library. Note that the use of an external text editing program, such as Emacs, it not a vital part of this course as DrScheme contains its own internal editing system. However, if you are so inclined, it may be a good time to start getting used to using other editing programs, as they will be vital later on in your computer science education.
bash, but if
you are accustomed to another shell, stick with it.mail or pine are available on the
Linux machines, mail is installed as /usr/bin/mail and
pine is installed as usr/local/bin/pine.man command to the
shell, but I recommend Xman, running in its own window, whenever you
are on a graphics terminal. The command is
//usr/openwin/bin/xman on the classes account and
/usr/X1186/bin/xman on the Linux machines. A lot of
documentation is moving to the texinfo format. Use the
info command, or invoke texinfo from
Emacs.
