The Office of Disability Services will provide photocopying or carbonless impression paper, whichever works best for those involved. Taking notes for another person may help you take better notes for yourself, and volunteer service is often viewed favorably by employers when it appears on a student's resume. If necessary, however, you can be paid by Disability Services as a student worker, provided the student receiving the notes has attnded classes. Anyone interested in serving as a note taker should see me for a quick moment after class or should mailto:rapaport@cse.buffalo.edu directly, to give me your name and contact information for the studnet.

(I'm sorry if that sounds uncaring or overly rigid, but in a class of this size, it's necessary to stick with the rules. The HW is due at the beginning of class. I will probably not collect it until after I have made some announcements, so you can be one or two minutes late, but after I collect it, all papers that arrive afterwards *will* be considered late. Don't forget that you are entitled to one late HW with no penalty and that there will be opportunity later in the semester to make up for some late HWs.) ------------------------------------------------------------------------ William J.

The rest of you can delete this message. ------------------------------------------------------------------------ WELCOME TO THE CSE 111 E-MAIL LISTSERV FOR FALL 2004! ------------------------------------------------------------------------ I will use this mailing list to post important updates, additions, corrections, etc., that I may not have time for in lecture. The TAs will use this mailing list for similar purposes. And YOU can use this mailing list to discuss topics from lecture, to ask questions, to get further information, ... If you prefer to contact any of the TAs or me in private (i.e., if you don't want everyone else in class to know what you're asking), then please send us private email (our email addresses are on the syllbus). However, I reserve the right to re-post such email---without your name or any other identifying information---if I think the question and its answer are of general interest. If you do not want me to do this, please let me know in your email message. And now, here are... The 5 Commandments of Computer Security: ---------------------------------------- I. Thou shalt maintain the security of thy computer accounts and thy written work. (In plain English: Practice "safe" computing, and don't let anyone copy your work!) II. Thou shalt not share passwords with anyone, nor write thy password down where it may be seen by others. (In plain English: Make sure no one except you knows your password or can find it out!) III. Thou shalt not change permissions to allow others to read thy course directories and files. (In plain English: Don't let anyone else use your account!) IV. Thou shalt not walk away from a workstation without logging out. (In plain English: Always log out!) V. In groups that collaborate inappropriately, it may be impossible to determine who has offered work to others in the group, who has received work, and who may have inadvertantly made their work available to the others by failure to maintain adequate personal security. In such cases, thou shalt all be held equally liable. (In plain English: If your friend copies your work, BOTH of you will be held equally responsible!

After the 128s place, comes the 256s place (256=128*2), then the 512s place (512=256*2), etc. You will definitely need more than 8 bits to represent any number greater than 255 (which is the largest number you can represent in 8 bits).

In particular, do not use spaces to separate words (and it's also a good idea not to use apostrophes, commas, etc.). E.g., instead of "cse 111 hw2.doc", name it "cse-111-hw2.doc" (The reason has to do with Unix file systems; most of the faculty and TAs use the Unix operating system, which cannot easily handle files with blank spaces or certain other weird characters in their names.)

The point I was trying to make is that, *if* our perceptions of the real world are really discrete, then the fact that digital computers can only represent things discretely is *not* a limitation on what they can represent. A few of you asked for further information on this. My source was an article by Oliver Sacks that appeared in a recent issue of _The New York Review of Books_. Here's a link to a *preview* of the article.

The problem has 5 parts, not 4, and none of the answers could possibly be "false". In any case... The HW *defines* "nor" as follows: "x nor y" means: not(x or y) So all you have to do is construct a truth table for "not(x or y)". To do that, first do the truth table for "or". Then do the truth table for "not" applied to that result, the way we did a similar problem in lecture. Don't try to assume that the *logical* connective spelled "nor" means exactly the same thing as the *English* word spelled the same way. Actually, however, it does! To say that it is neither the case that 1+1=3 nor the case that 1+1=4 is to say it is not the case that either one is true. This is, in fact, the same as saying that both of them are false (i.e., "x nor y" is logically equivalent to "not(x or y)", by definition, and both are logically equivalent to "(not x) and (not y)".)

I am confused as to how to construct this, would | it be the same as a table for ( x nor y) and not ( x nor y)? I would | really appreciate it if you were able to shed some light on this | problem. First, everyone please note: I read this query this morning (Wed); it was sent late last night (around 11 pm). Questions sent that late will most likely *not* be answered in time for you to make use of the answer, since I usually do not read email at home in the evenings. Second, you should not be putting your HW off till the last minute! I have received a flurry of questions late yesterday. You should have started working on this homework when it was assigned, not the night before it is due. Please re-read the section of the syllabus on time management at: http://www.cse.buffalo.edu/~rapaport/111F04/syl.html#time-management Finally, my reply to the query: To construct the truth table for (x nor y) nor (x nor y) first construct a truth table for "x nor y". Then apply that truth table to two copies of itself; i.e., have a column of your truth table that is just like the column for "x nor y", but where "x" is replaced by "x nor y" and "y" is also replaced by "x nor y". If that's confusing, consider this: (x nor y) nor (x nor y) is essentially a "nor" statement of the form "A nor B", where A = "x nor y" and B = "x nor y". You know how to construct a truth table for "A nor B". But the truth values that you would use for A and for B will be whatever you find in the column for "x nor y", since that's what A and what B are. If you still are confused, here's an analogy. Suppose I had asked you to construct a truth table for: (x and y) and (x and y) You'd need 2 "input" columns, one for "x" and one for "y". You'd need an intermediate column for "x and y", and, if you'd like, you could have a 2nd intermediate column for the other occurrence of "x and y", though of course that column would be identical to the other one. Finally, you'd need an output column for "(x and y) and (x and y)": I/P: Intermediate column(s): O/P column: x y (x and y) optional column: (x and y) (x and y) and (x and y) - - --------- -------------------------- ----------------------- 0 0 0 0 0 0 1 0 0 0 1 0 0 0 0 1 1 1 1 1 From owner-cse111-fa04-list@LISTSERV.BUFFALO.EDU Wed Sep 29 13:09:12 2004 for ; Wed, 29 Sep 2004 13:09:11 -0400 (EDT) for ; Wed, 29 Sep 2004 13:09:11 -0400 (EDT) CSE111-FA04-LIST@LISTSERV.BUFFALO.EDU; Wed, 29 Sep 2004 13:07:46 -0400 17:07:45 -0000 i8TH7j95007793 for ; Wed, 29 Sep 2004 13:07:45 -0400 (EDT) cse111-fa04-list@listserv.buffalo.edu; Wed, 29 Sep 2004 13:07:45 -0400 (EDT) Date: Wed, 29 Sep 2004 13:07:45 -0400 Reply-To: CSE 111 Great Ideas in CS From: "William J.

Those students will be marked "1 day late", following the policy on late HWs as stated on the syllabus at: http://www.cse.buffalo.edu/~rapaport/111F04/syl.html#late I have this policy for several reasons: 1. This is a large lecture class, and having a uniform policy on when to hand in HWs makes things easier to manage. 2. I collect HW at the *start* of class in order to try to eliminate the number of people who skip class but come in at the end to hand in their HW. 3. This also encourages those of you who use the university computer printers to print out your HW to do this early enough so as not to miss class. There is often a *very* long wait for computer printouts, and you are advised to print out your HW no later than the night *before* the due date (see my earlier posting about doing your HW on time! :-) This may become more important when we begin Karel the Robot, which may require you to use the campus computers and printers. 4. If you were unavoidably late to class because your previous class went overtime or was on the South Campus, or because there was a traffic jam, or whatever, and that's why you handed your HW in at the end of class, then it's still late. But you are allowed to drop your lowest HW grade, so this one time shouldn't hurt your grade. Moreover, there will be other opportunities to make up for low HW grades. As the syllabus states, if you know now that you are always going to be late for class on the day that HW is due, please let me know. If you have a good reason (e.g., class at South Campus, etc., but *not* "I always oversleep" :-), then I won't mark you late. But you have to let me know.

(I don't want to take up time for material that *will* be on the exam on this material--which, however interesting--*won't* be on the exam.) ======================================================================== Place-value notation for decimals represents numbers this way: 1213.14159 Here, "1213" is called the "mantissa", the "." is called the "decimal point", and "14159" is the number to the right of the decimal point (no name). As you know, the numerals (reading from left to right) represent the following values: (Some notation: "*" represents multiplication, and "^" represents exponentiation; i.e., "10^3" represents 10 * 10 * 10.) 1 represents 1 * 1000 i.e., 1 * 10^3 2 represents 2 * 100 i.e., 2 * 10^2 1 represents 1 * 10 i.e., 1 * 10^1 3 represents 3 * 1 i.e., 3 * 10^0 following this pattern after the decimal point, we get: 1 represents 1 * 0.1 i.e., 1 * 10^(-1) 4 represents 4 * 0.01 i.e., 4 * 10^(-2) 1 represents 1 * 0.001 i.e., 1 * 10^(-3) 5 represents 5 * 0.0001 i.e., 5 * 10^(-4) 9 represents 9 * 0.00001 i.e., 9 * 10^(-5) or, in another notation, after the decimal point we have: 1 * 1/10 4 * 1/100 1 * 1/1000 5 * 1/10000 9 * 1/100000 So much for classical decimal numerals. Now how about binary numerals? Consider the binary numeral: 101.01101 Here, again reading from left to right, we have: 1 * 100 i.e., 1 * 2^2 i.e., 1 * 4 0 * 10 i.e., 0 * 2^1 i.e., 0 * 2 1 * 1 i.e., 1 * 2^0 i.e., 1 * 1 then comes the "binary point" [actually, it's called a "radix point"] 0 * 0.1 i.e., 0 * 2^(-1) i.e., 0 * 1/2 1 * 0.01 i.e., 1 * 2^(-2) i.e., 1 * 1/4 1 * 0.001 i.e., 1 * 2^(-3) i.e., 1 * 1/8 0 * 0.0001 i.e., 0 * 2^(-4) i.e., 0 * 1/16 1 * 0.00001 i.e., 1 * 2^(-5) i.e., 1 * 1/32 This next gets turned into "floating point" notation, so called because the location of the radix point "floats", or moves around: In floating-point notation, you only need to represent 3 things: the sign (+, -) the mantissa (the integer value to the left of the point) the exponent (a clue as to the location of the radix point) In decimal floating-point representation, the exponent is the power of 10 that the place value is multiplied by. In binary floating-point representation, the exponent is the power of 2 that the place value is multiplied by. Finally, each representation scheme decides on a fixed number of places for representing the mantissa. For very large numbers, or for numbers with lots of digits to the right of the point, you have to cut off the value somewhere, and then round off. For simplicity in explaining this notation, I'll use decimal numerals. Binary is the same, except that "2" replaces "10", and we use binary bits instead of decimal digits. For example, suppose we allow 5 digits for the mantissa. To represent: Use: 123.00 12300 * 10^(-2) Note: The "-2" exponent tells you to move the decimal point 2 places to the left, i.e., to divide by 100. (12300 divided by 100 = 123.00) 12345.00 12345 * 10^0 -120.01 -12001 * 10^(-2) 13574821 13575 * 10^3 (which = 13575000) In the last example, note that we rounded up. So there's a "round-off" error of 13575000 - 13574821 = 179. This is relatively small; 179 is only 0.00131% of the correct number. If that error is still too big, then you have to use a larger mantissa to be able to represent more information. Binary floating-point representation usually uses 64 bits: 1 bit for the sign 52 bits for the mantissa 11 bits for the exponent If a memory cell can only hold 8 bits, you need 8 memory cells to store all 64 bits of information (because 8 bits per cell * 8 cells = 64 bits). For more information, go to the new section of our "Binary Codes" website, called "Binary representation of negative and real numbers": http://www.cse.buffalo.edu/~rapaport/111F04/binarycode.html#negative ======================================================================== Here are the names of the different kinds of numbers: whole numbers: 1,2,3,... (non-negative) integers: 0,1,2,3,... integers: ...,-3,-2,-1,0,1,2,3,... rationals: all fractions i.e., all numbers representable by a decimal part to the right of the decimal point that eventually repeats, like: 3.111111.... 0.500000.... 1.142857142857... irrationals: all non-repeating decimals, including things like the square root of 2, pi, etc. imaginaries: things like the square root of -1.

To: CSE111-FA04-LIST@LISTSERV.BUFFALO.EDU ------------------------------------------------------------------------ ERROR IN HW #6 !!!! ------------------------------------------------------------------------ I'm really not having much luck with HW 6! First I accidentally send out the answers to an early draft. Now I see that there's a serious mistake! I have defined the "nand" connective incorrectly. Here is the correct definition. I will update the online version of the HW, too. The truth value of "x nand y" is FALSE if the truth values of x and of y are both TRUE; otherwise, the truth value of "x nand y" is TRUE. (In other words, "x nand y" is logically equivalent to "not(x and y)".) (That last parenthetical remark is still correct.)

Remember: Negation applies to only a single proposition. You can compute the negation of x, but if you need to compute the negation of (x or y), you first have to compute the truth values of (x or y), and then simply switch 0 with 1, and vice versa (which is what negation does). | Is it just | x and y or do we need to consider conjuntion in the input. I assume you're referring to the HW, which asks for "nand". You're right: First figure out the truth table for conjunction; then apply negation to that, as in your example of "or" and "nor", below. | Example: NOR | x y x or y x nor y | 0 0 0 1 | 0 1 1 0 | 1 0 1 0 | 1 1 1 0 | | I was looking at your flow charts with the answers from the first | set of questions and have not been able to figure it out. That last question is the kind of vague question I can't answer unless you show me exactly what part of it you can't figure out.

There were two parts: one for the labs and the TAs, one for the lecture and me. I'll review the lab comments with the TAs, and they can address your concerns directly. Here, let me try to summarize and respond to your comments on the course as a whole. In general and on the whole, you seem happy with the way things are going. A few of you noted some areas where things might have been done differently or areas that I need to take into consideration. ======================================================================== Need for improvement: ------------------------------------------------------------------------ 1. The "biggest" complaint, though there were really only a few, concerned the amount of time I took on binary representation and truth tables (too much) and on Turing machines (not enough). Of course, it's too late for me to do anything about that now, but I'll try to fix that in future versions of the course. 2. Several of you wanted to see the topics related more to concepts that you "understand" or to "daily life". That's a little vague. My assumption has been that you all use computers, and I'm trying to show you how they work from a theoretical perspective (i.e., not the hardware, but the software). If any of you have a more explicit example of ways in which I can make the topics more relevant, please let me know. By the way, the main topic for the second half of the course are the promised "algorithmic problem solving" techniques; these might seem even *less* "relevant", but--if you practice them--can be very applicable to all areas. 3. Another problem, of a more practical nature, is my writing on the blackboard, which is sometimes illegible or hard to decipher because of abbreviations. I'll try to do better! But please don't be afraid to raise your hand (or yell out if my back is turned :-) to ask me to clarify anything I've written. 4. Speaking of raising your hands, some of you said that you'd prefer me not to lecture so much and to answer more questions. I'd be happy to; please *ask* more questions :-) 5. Also on the topic of topics that I talk about, some of you wish that I'd spend less time going off on tangents or discussing things that you don't need to know. I can only assume that you mean things that don't get asked on exams or homeworks. But I can't ask about everything on exams and homeworks, and if I only talked about things that I'll ask you about, I wouldn't have much to say. (Yes, I can hear some of you thinking, "That's OK!" :-) Always pay attention to tangents; sometimes they contains words of wisdom that you will recall long after you forget how to convert binary to decimal. 6. The reading assignments have gotten mixed reviews from those of you who mentioned them. The Hillis book is for background reading; it's not a text, so I can't really treat it as one. The Karel book *is* a text, and we'll be going through it in more detail. We'll return to the Hillis book towards the end of the semester. 7. Several of you think I should be covering the topics faster. From the kinds of questions we've been getting during office hours and via email, I think there are just as many of you who think I should be covering them more slowly. Nevertheless, the pace should pick up with Karel. (There's an old saying: Be careful what you wish for; you might get it.) 8. A few of you think that our office hours have been erratic and inconsistent; others seem quite happy with them. Occasionally, we have to cancel or change hours, but we always let you know. You are always free to go to *any* TA, not just yours, for help, as well as me. And you're always free to make an appointment for a more convenient time. 9. Finally, at least one of you wishes that the class before ours should finish on time. Amen! Things you like: ------------------------------------------------------------------------ You seem to like the HWs, explanations, organization, and the website. In general, people seem pretty happy with the way things are going. Thanks! If you have any further comments, please share them with the class via the Listserv, with me via private email, or anonymously by putting a note in my mailbox in Bell 211.

Several of you felt you'd like to see more of a close connection between labs and lecture, that you'd like me to be more involved in labs. In fact, I meet with the TAs on a weekly basis, and provide them with guidelines on what I would like them to cover in the labs. They have a certain amount of freedom of choice among several items that I suggest, since each lab has a different "feel", each lab will have covered slightly different things in previous sessions, and the students will have slightly different questions. Again, if you have further comments, questions, or suggestions, please let me know. ------------------------------------------------------------------------ William J.

To start, | I give a preliminary definition of something like consciousness, what I | call a Conceptualizing Strategizing Control (CONSCS) System. The point | of a formal definition is: 1. to prove theorems, including: "A | conscs entity in a completely deterministic world can have free will." | (Of course, this requires defining conscs, entity, and free will.) | 2. to discern if the definition is likely to be "right." We can think | of the implications of a proposed definition as testable hypotheses that | we pit against our intuitions and known experiments. This is what makes | our "definition game" a science, and not just some dogmatic imposition | asserting how minds work. | | | The preliminary theory has plusses and minuses. The positive insights | include nice explanations for free will and self awareness. (These do a | reasonable job of demystifying Samuel Johnson's enigma: "All theory is | against the Freedom of the Will: all experience is for it.") The | negatives have to do with the theory's explanation of the emotions, like | the suffering that is caused by pain. (It is not immediate how the | theory accounts for suffering.) | | | If you're looking for the final answer to what is consciousness, you | will be deeply disappointed. This is much too preliminary for that. | What this talk does do is to give some idea how two theoretical computer | scientists (me and Steven Rudich), one graduate student (Ryan Williams), | and one undergraduate (Brendan Juba), approach this difficult but very | interesting problem. | | | Bio: Dr. Manuel Blum is the Bruce Nelson Professor of Computer Science | at Carnegie Mellon University. Previously he was the Arthur J. Chick | Professor in Electrical Engineering and Computing Sciences at the | University of California at Berkeley, where he served from 1968 to | 2000.

Depends on the question :-) | Do you want us to copy the program example from the book to Karel and | then correct them there, then printing. I'm not sure which question you have in mind. The questions from p. 6 are short-answer questions that don't require use of the Karel software. | What about drawing a map of the | final situation as in question 1 on page 19 should this be done on a | separate sheet of paper or is there someway to do it Karel? The question from p. 19 requires you to draw a picture of the final situation; you could do this with paper & pencil the way I do it on the blackboard, or--depending on how comfortable you feel with graphic software like MS Paint--you could run the program and cut & paste the final situation, then print it out. [see below[ As for correcting any errors, you could either do this online and print it out from the Karel software, or you could do it with pencil & paper, just indicating the correction(s) that have to be made, if any. The question from p. 20 (#3) is a very short answer that could either be printed out from the Karel software or written with pencil and paper. The question from p. 27 should be done using the Karel software and printed from there. However, attention all Mac users: Those of you who have replied to my email may do this one with pencil and paper. ======================================================================== How to cut and paste a Karel world (for Windows users): 1. Create the world, either using the Karel software or by having Karel execute a program. 2. Hit the "print screen" button to save an image of your entire screen; this works best if you get rid of anything on your screen other than Karel's world. 3. Open Paint, and use the "paste" command to paste the image of your screen; you can do this by right-clicking your mouse and selecting "paste". 4. I forget whether there's a way to crop that image to omit everything except K's world (and my version of Windows in my office where I'm typing this lacks Paint, so I can't try it out), but if there is, do that. 5. Otherwise, just print from the Paint program and cut/paste onto your homework. 6. It really might be easier to draw the world with pencil & paper :-) From owner-cse111-fa04-list@LISTSERV.BUFFALO.EDU Sun Nov 7 14:41:42 2004 for ; Sun, 7 Nov 2004 14:41:42 -0500 (EST) for ; Sun, 7 Nov 2004 14:41:42 -0500 (EST) CSE111-FA04-LIST@LISTSERV.BUFFALO.EDU; Sun, 7 Nov 2004 14:41:25 -0500 19:41:25 -0000 iA7JfP95021676 for ; Sun, 7 Nov 2004 14:41:25 -0500 (EST) cse111-fa04-list@listserv.buffalo.edu; Sun, 7 Nov 2004 14:41:25 -0500 (EST) Date: Sun, 7 Nov 2004 14:41:25 -0500 Reply-To: "William J.

It | seems that the students who didn't do well are being rewarded with a an | opportunity do great and the students who did well aren't rewarded at | all. I got a perfect score on the midterm but I know I am not as | confident about the second exam. I am going to be studying just as hard | as students who didn't do well on their midterm and if we both do well, | the student who didn't study for the midterm receives a perk?!? A fair question. I tend to believe in the "contract" theory of learning: You keep studying a subject until you learn it. Following that to its logical conclusion, everyone would eventually get an "A", since they wouldn't get any grade until they've learned the material. Allowing a cumulative final exam to supersede a midterm exam is a partial implementation of this theory. If you learned the first half of the material by the midsemester point and got an A, you won't lose that A even if you do slightly worse on the final exam. But if you do better on the final exam, then you're not penalized for not having fully learned the material the first time through. Arguably, *not* replacing a low midterm grade by a high final grade is just as unfair as replacing might be. If so, then I think the balance leans towards rewarding a higher final grade, since that is a measure of progress. It would certainly be unfair to say that the final exam grade replaces *everyone's* midterm exam grade. So those who do better on the midterm than on the final get the "perk" of not having that midterm grade ignored.

This paper makes various estimates and compares the answers with the estimates of disk and tape sales, and size of all human memory. There may be a few thousand petabytes [*] of information all told; and the production of tape and disk will reach that level by the year 2000. So in only a few years, (a) we will be able save everything - no information will have to be thrown out, and (b) the typical piece of information will never be looked at by a human being. * Here are the names of the units of very large storage sizes: gigabyte 1,000 megabytes terabyte 1,000 gigabytes petabyte 1,000 terabytes exabyte 1,000 petabytes From owner-cse111-fa04-list@LISTSERV.BUFFALO.EDU Tue Dec 21 10:42:43 2004 for ; Tue, 21 Dec 2004 10:42:43 -0500 (EST) for ; Tue, 21 Dec 2004 10:42:43 -0500 (EST) CSE111-FA04-LIST@LISTSERV.BUFFALO.EDU; Tue, 21 Dec 2004 10:42:19 -0500 15:42:15 -0000 iBLFgF95010153 for ; Tue, 21 Dec 2004 10:42:15 -0500 (EST) cse111-fa04-list@listserv.buffalo.edu; Tue, 21 Dec 2004 10:42:15 -0500 (EST) Date: Tue, 21 Dec 2004 10:42:15 -0500 Reply-To: "William J.
