7/19: In case you missed my announcements in lecture: Due to a very serious family emergency I am leaving Berkeley at the end of this week to go home (to southern California). My replacement will be Ana Ramirez Chang, who is a grad student in CS. I'm very sorry for having to disrupt the class like this and I hope that you all will understand, but I will remain involved with the course, and I will be glad to continue to answer questions by e-mail and on the newsgroup. I will also possibly hold "online office hours" on some chat program, such as AOL instant messenger, ICQ, or Google chat. -- Kevin

7/13: Go to Gap's page for review session notes and solutions.

7/11: The midterm location has changed. It will be in 145 McCone. Please take note.

In lecture I said that I was going to post some old midterms online, but it turns out that all of the old midterms that I have saved are all available on the HKN exam archive. So just use that.

7/10: You don't have to do exercise 1.16 on homework 2A, because I already gave the answer away in lecture. Thanks to Jason Gowan for pointing this out to me.

Also, here is the website for submitting anonymous feedback that I mentioned in lecture today. Please use it, especially if you have any suggestions for us (the staff).

Assignments

There are two labs per week. Lab assignments are worth zero points (but you still should do them!). Homework assignments are assigned (and will be posted online) every Monday and Wednesday, and are due the Wednesday of the following week at 11:59 PM. Homework is graded on effort; if you show that you made a reasonable attempt on every problem, then you will get full credit. Projects follow a more irregular schedule. Projects are graded on correctness and understanding. There will be four projects. The first two projects will be done individually, and the last two projects will be done in groups of two students. It is mandatory to turn in a paper copy of your projects and optional for homework assignments. The drop box for paper copies is in 283 Soda.

Solutions to all assignments will be posted in the solutions directory, which can be accessed on campus computers only.

Exams

Each midterm is worth 40 points, or about 13% of your course grade. There will be three midterms. The midterms are closed-book, closed-notes, closed-electronic-devices, closed-friends, etc.

Midterm 1 will be on Friday, 7/14/2006, 4-6 PM, in 534 Davis 145 McCone. It will emphasize weeks 1 and 2, but it will have one question on week 3 material. You can bring exactly one standard size (8.5 x 11) page of notes (front and back).

Midterm 1
Midterm 1 solutions

Midterm 2 will be on Friday, 7/28/2006, 4-6PM, in 10 Evans Hall. It will cover: data directed programming, message passing, tagged-data, deep-lists, trees, pairs/lists, object oriented programming (above the line), and Scheme-1

Midterm 2

Midterm 3 will be on Friday, 8/10/2006, 4-6PM, in 10 Evans Hall. It will cover: Environment diagrams, local state, mutation including lists (set-car! set-cdr!) and vectors, concurrency, metacircular evaluator.
You may bring up to 3 standard size (8.5 x 11) pages of notes (front and back).

Midterm 3

Old Midterm 3 Questions

Final Exam will be on Friday 8/18/2006, 3-6PM (not Berkeley time) in 60 Evans Hall


Tentative Course Schedule

Most online course materials will be in PDF format. There are many free PDF viewers available. Adobe Acrobat is a good one to get.

Warning: Schedule is subject to change, especially for the later weeks. Also, since this is my first time as the instructor for this class, my notes will probably be relatively rough and subject to additions and edits.

(Reading assignments for each lecture are in parenthesis. Section numbers refer to the textbook, Structure and Interpretation of Computer Programs, unless otherwise noted.)

I intend to cover all of Chapter 1, most of Chapter 2 (we will probably skip about half of the "Example" sections), most of Chapter 3 (we probably won't spend too much time on streams, and we'll skip some subsections here and there), Section 4.1, and some combination of Sections 4.2, 4.3, and 4.4. In addition, we will be doing a few things that are not in the textbook, including object oriented programming.
