News for UCLA Computer Science 131, Winter 2004

2004-03-17

• Java, Mono, or C++ reports on a recent language war.
• Partial midterm answers are available.

2004-03-11

A typo in Project 2 has been corrected. The correct status code for Forbidden is 403, not 404. Please see Internet RFC 2616 §10.4.3 for details.

2004-03-05

• Project 2 is available; it reflects the tentative project discussed in class Wednesday and in discussion today.
• The Twisted version number has been updated from 1.1.0 to 1.2.0 in resources.

A special case has been added to Homework 4 when when x is a NaN and x is y. In this special case, it is OK if cmp(x,y) returns 0; internally Python uses is as a short-cut before invoking your comparison method, and there's no easy way to change this without modifying the Python implementation. FloatingPointError must still be raised if the arguments to cmp are distinct objects and one is a NaN.

• Homework 4's due date has been extended to Thursday. Project 2's deadline has also been shifted back; but remember, no assignment will be accepted after the last day of class.
• Homework 4 has been clarified for 3-argument pow: it should behave as with float, and thus should always raise TypeError.
• For your convenience, the source code for Python 2.3.3 has been placed into ~eggert/src/python/Python-2.3.3 on SEASnet.

Homework 4 is available; it is essentially what was discussed in class yesterday.

2004-02-17

Homework 3 is available; it is due one week from today.

2004-02-12

• Homework 1 grades are available; please see Jonathan's comments on the grading.
• Homework 2 has been simplified. You need to implement only the forwards case, where the first argument to english_c/2 is a ground term. If you want to do the original version of Homework 2, including the "backwards" case as well (where the second argument is a ground term), you can turn this in as well, for 50% extra credit.
• Some examples have been added to Homework 2.
• In Homework 2, the C operators | and % have been quoted, as discussed in class.

2004-02-09

• Homework 1 now contains a solution.
• The midterm will cover all the material covered in lecture and discussion sections, along with Homeworks 1 and 2, Project 1, and Sebesta §§1-3.3, 15, 16.
• Winter 2003's midterms and answers are available. However, that quarter we covered topics in a different order, and used a different language (m4 rather than Python). Therefore, not all of the questions and answers will be directly applicable for studying for the midterm this quarter, and some of this quarter's pre-midterm topics (notably Prolog) were not covered by the old midterms. Also, an earlier edition of Sebesta was used, so the page and section numbers might not match your copy of Sebesta.

2004-02-04

• Homework 2 is available.
• The deadlines for Project 1, Homework 2, and Homework 3 have been adjusted.
• Jonathan's office hours have been added to the course schedules.

2004-02-03

begin has been added to the list of Scheme primitives that a matcher can use in Project 1. This isn't strictly necessary, since (begin A B C) is equivalent to ((lambda () A B C)), but it is a convenience.

2004-02-01

In Project 1, the last line of nonemptymatch has been changed from (not (eq? frag frag1)))))) to (and (not (eq? frag frag1)) frag1))))), so that on success it returns the unmatched suffix rather than simply returning #t.

As previously announced, Jonathan will not be on campus Friday. The morning section will still be held at the same time/place (10:00, Public Policy 1234). Gary Underwood, a previous TA for this course, has graciously agreed to teach the section. The afternoon section will not be held. To make up for this, Jonathan is holding a section tonight at 19:00 (to let people eat between 131's), hopefully in the same room the usual afternoon section (Boelter 5264). If the room is occupied, he'll leave a note as to where to go. Those of you who are in the morning section are welcome to join.

2004-01-23

• Project 1 is available. Its due date has been changed to 02-02. Homework 2's due date has also been moved, to 02-09.
• As was mentioned in class Wednesday, Homework 1's due date was moved to 01-21.

2004-01-15

A web discussion board is available for the class. Jonathan will monitor it regularly.

2004-01-07

• The room for discussion section 1B (Friday at 10:00) has been changed to Public Policy 1234.
• Obtain or renew your SEASnet account right away, as there are occasionally delays before your account is activated.
