You will need the password sent in email to view them. Exam 4 was graded to give you your best percentage with or without problems 4b and 5a, which most people missed. We have decided on final letter grades, so the letter grades on the grades page are the ones submitted to the Registrar. You can stop by after 10am any day the rest of the week and get your exam from Gary (except Friday 9:45-2pm).

See the exams page for copies of old exams. The final exam will be in our normal classroom on Mon., Dec 11, 12:00pm-2:00pm, as has been in our syllabus.

If you are working at home, download hw342.zip from the course web page. On Thursday at 4:55pm, we remade the course libraries with a better (more elegant) version of the code for deref and eval-thunk that corresponds to our discussion in class on Tuesday. If you are working at home, to get the new code, you should download a new copy of the homework zip file hw342.zip, and a new copy of the course library, lib342.zip, and rerun the setup program (see the course library page) after doing that.

You should already be able to do most of these problems, and so we suggest that you most of them this week, instead of next week. If you are working at home, download hw342.zip from the course web page. At 9:14pm on Nov 15, we fixed the example in problem 4(a), thanks to Kirk Sykora, which was missing an derek. The use of "rx" on the last line should have been "deref(rx)". Com S 342 News http://www.igert.org http://www.igert.org/ Sat, 11 Nov 2006 23:07:00 CST IGERT programs are recruiting graduate students for next year. IGERT programs provide generous stipend ($30,000 per year) and tuition support for students through the National Science Foundation. The website: http://www.igert.org has links to over 100 programs throughout the nation that offer this support. See also the undergraduate summer research web page: http://www.igert.org/reus.asp.

If you are working at home, download hw342.zip from the course web page. On October 25 we fixed a problem with the numbering of the last problem (which is problem 9, not problem 1). On October 29 we corrected problem 4, which is now correctly noted as an extra credit problem.

The penalty for turning in a problem after class starts is the same as the penalty for turning it in by 5pm that day, which is meant to encourage you to come to class instead of working on homework during class. You can finish up homework after class without additional penalty that day. Please print out what you have done before class and hand that in to avoid penalties on those problems. Com S 342 News http://www.paulgraham.com/avg.html http://www.paulgraham.com/avg.html Fri, 25 Aug 2006 15:39:00 CDT Why learn Scheme? Besides needing it for the study of programming langauges in our course, there may be other reasons, as explained in this essay Paul Graham about the expressive power of Lisp and how it helped in a startup company. Note that Scheme is a dialect of Lisp. Home Page of Com S 342 http://www.cs.iastate.edu/~cs342/library.shtml http://www.cs.iastate.edu/~leavens/ComS342-EOPL2e/library.shtml Sun, 19 Mar 2006 00:00:00 CST The course library tells how to work with DrScheme at home, including getting your own copy of the course Scheme library, lib342.zip. If you get errors when installing a new version of the li342.zip on your homemachine, and if you had previously installed an old version, then try deleting the both old library directories (PLT/collects/lib342 and PLT/collects/typedscm) first, and then reinstall and run the setup program again. Contact the course staff if that doesn't help. You can always use the department Unix machines which have a working install if all else fails.
