One more announcement: I'm leaving for a week-long trip to a software engineering conference in Toronto early Monday morning. What this means is that I will not be in Boudler to send out "notification" messages of receiving your exam next week. I return to Boulder on the 20th, and I will send out my notification messages on the 21st when I return to campus. Note: I am taking homework 5 and the extra credit assignments with me, and I will grade those while I'm away next week.
1:30:32 PM
Note to CATECS students who did not receive the corrected page 9 of the final exam. I will, of course, not downgrade you if, for whatever reason, your test proctor did not receive the updated page 9 of the final exam. No worries!
1:28:09 PM
CATECS Students:Today is the last day to submit Homework 5 and the Extra credit assignment. Due to the large amount of grading that I face (e.g. 32 final exams for CATECS students), I will not accept late homeworks or late extra credit assignments. FYI.
Wednesday, May 9, 2001
10:19:56 AM
In-Class Students: I have placed your final exams in room ECOT 717, where the department admin's office is located. Bring your id and you can pick up your exam during normal business hours.

ATTENTION CATECS STUDENTS!
I discovered on Thursday that there was a problem with one of the questions on the final. I have corrected the problem and I gave an updated final to CATECS to re-send to your test proctors. The problem appears on page 9 of the final. The corrected page 9 has the following phrase handwritten on the bottom of the page "corrected version". Be sure that your test proctor gives you the test with the corrected page!

I have placed four examples of student's homeworks on the website:
Matthias Hauswirth's Homework 2.
Edmon Begoli's Homework 3.
Nick Mezei's Homework 3.
Tom Polanski's Homework 3.
I hope you find these examples useful!
4:40:04 PM
Midterm: I announced this in class, but I wanted to repeat the information here. The midterm is a closed book, closed notes test. Bring a couple of pencils and a few pens with you. While you can do work in pencil, I prefer final answers to be written in pen. The test is printed single sided, so you will be able to use the back side of the exam as scratch paper.
1:27:16 PM
I just received a call from a librarian at the Math library with some disturbing news. Apparently, a student has been abusing the privilege of viewing the tapes of our class lectures by 1) vandalising the tapes and 2) removing them from the library. While we do not have any proof that it is a student who is currently enrolled in the class, it seems reasonable that only currently enrolled students would be interested in those tapes. This assumption leads to this message, which I will repeat in class tomorrow.
The tape viewing system at the Math library, works on the honor system. There is a room that allows students to pick up a tape and view it on one of the provided machines. Once you are finished viewing the lecture, you are supposed to return the tape. You are not supposed to leave the library with the tapes, and you should be respectful of the fact that other students may want to view these tapes.
The tapes are protected by a metal strip that is supposed to sound an alarm when a student attempts to leave the library with the tape. The vandalism that is occuring is that a student is ripping the metal strip off the tape to avoid detection when he or she leaves the library with that tape. Since the student who is doing this, is, in essense, destroying school property, there can be serious consequences if that student is caught.
I have two comments on this behavior: First, I cannot believe that any university student (undergraduate or graduate) would behave in this fashion. We are all here to learn and to expand our skills, vandalism should be the last thing on any of our minds. Second, the ability to view these tapes outside of class is a privilege not a right. In-class students are supposed to attend class in the studio. The tape library is maintained to allow those students who missed a class to see what occurred. Remember, if this was not a CATECS class, there would be no tapes for you to see if you missed a class.
This is a privilege that can be (and will be) revoked if this behavior continues. I have asked the librarian to keep me informed and I intend to follow up with her to monitor this situation.
9:59:28 AM
For those of you who have submitted homework assignments by fax or hard copy, please let me know if you would like the fax and/or hard copy returned to you. Otherwise, I will wait one week from this announcement and I will recycle all homework assignments that I have in my possession.

11:50:59 AM
Note to CATECS students: The midterm has been released to CATECS and they will be mailing the exam to your designated test proctors. There will be no new material covered on Tuesday, March 6th, so the last lecture you need to see to prepare for the midterm is Lecture 14. (Actually, I may present new material on Tuesday, March 6th, but it will not be required for the midterm.) CATECS students, you have until March 15th to take the exam. That is, your exam must have a postmark no later than March 15th. Contact your test proctors to arrange a time to take the exam. FYI.

At the end of lecture 11, I displayed a class diagram that was too complex for students to draw by hand in the time we had remaining. That diagram has now been scanned in and is available for study. By thursday lecture, take a look at the diagram, and write an english description for it. That is, do the reverse of what I had you do at the end of class: e.g. I gave you a textual description and had you create class diagrams, now do the reverse, generate the textual description from the class diagram. Have Fun!

I have deployed a Web-based system that allows students to view the grades that I have for them on-line. You should have received an e-mail message with your login information. Once you login, please change your password to something else, but please note: do not re-use a password that you have used on other accounts. These passwords are protected from outside hackers but can be discovered by someone who gains physical access to the server machine. So, use something that is easily remembered, but do not use a password that also works for your personal accounts.
Note: I deployed the system before grading homework 1 and homework 2, so the information is not quite current, but should be current by next week. FYI.

Note: if you are having problems finding a font that contains the ForAll (the upside down A) and Exists (the backwards E) quantifiers for your predicate logic assertions, try the following. Launch MS Word, and choose Insert->Symbol. In the resulting dialog, set the font to "Symbol" and look for the symbols. This solution worked on a PC running MS Windows 98 that I tried, and it worked for another student also using a MS Windows OS. Hope this helps!

More information on converting Postscript to PDF
Two students have written in with more information on converting postscript files to PDF files. Thanks to Sudipto Chakraborty and Nathan Blair for sending in this useful information! (Follow link above.)
Tuesday, February 13, 2001
2:07:58 PM
Just a quick note on Postscript and PDF files: The directions below for February 6th provide links and information on how to create Postscript files. If you print a document using the printer driver below, it will create a file with an extension of .prn. A .prn file is a Postscript file. On other platforms, the extension is .ps. So, both .prn and .ps files are the same type of file. A postscript file is not a PDF file.
In order to create a PDF file, you need to purchase Adobe Acrobat. Acrobat contains a program called Distiller that can take a Postscript file and convert it to a PDF file. So, if you use the printer driver below to create a postscript file, you can not use the Acrobat Reader to view that file. Acrobat Reader cannot view postscript files, it can only view PDF files.
2:06:29 PM
In the lectures section of the website, I have made the use case examples that I presented in class today available. You can look at the use cases as GIF images or you can download a 3.2 MB PDF file for viewing on your local machine.
Monday, February 12, 2001
3:23:56 PM
Note: slight change in schedule. I will devote all of Tuesday's lecture to Use Cases and we will pick up on Object and Class Diagrams on Thursday. As such, I will not be producing Lecture 9 slides for tomorrow. Stay tuned for Thursday's class notes that should appear by Wednesday.
1:34:30 PM
Quick note about the Midterm for CATECS students: I will be giving the midterm to CATECS on March 1st and they will send the midterm to your designated test proctor. Contact your test proctor to arrange a time to take the midterm. Your test proctor will then mail your exam back to me. Exams must be postmarked by March 15th. This policy allows you to receive your tapes for the lecture held on March 6th, in time to study and take the midterm by March 15th, which is one week after the in-class midterm. Send me mail if you have any questions.

Crash Course on Installing a Postscript Printer Driver on your Windows PC
Thanks to Sameer Totey for the pointer to the URL of the AdobePS Printer Driver.
Step 1: Downloads. First download the AdobePS Printer driver and then download the Acrobat Distiller Printer Description File. To do this, go to the following URLs:
AdobePS Printer Driver
Acrobat Distiller Printer Description File
Step 2: Unzipping. Unzip the printer description archive. Take note of the location where the printer description files are unzipped. On my PC, the default location was <C:\TEMP\ADOBE>. Remember this.
Step 3: Installing. Now, run the AdobePS installer. It will ask you a series of questions. The following answers worked for me on my PC (your milage may vary): When it asks if the printer is a local or network printer, pick local. When it asks what port to use, choose FILE: (if its available). Then, it will ask you to select a printer description file. The default choice is Generic Postscript Printer . This default should work okay, but I recommend selecting the Adobe Acrobat printer description file that is contained in the directory that was created in Step 2 above. The installer will ask you to configure the printer, you can just accept the defaults. The installer will ask you if you want this printer to be your default printer. I said Yes but if you already have a printer connected to your machine, I would probably say No . Finally, the installer will ask if you want to print a test page, I said yes . I was then able to convert that test page into a PDF file and all was well.
I hope this helps!

Lecture 8 is going to be taped early. In particular, I will be taping lecture 8 in the same CATECS studio that we use on Tuesday and Thurday from 1 PM to 2:15 PM on Wednesday. You can still attend lecture on Thursday because they will be playing the tape that we make on Wednesday during our normal lecture time. I would appreciate an audience, so if anyone can make it on Wednesday at 1 PM, please attend!

Answers to frequently asked questions:
1. The bookstore is out of the Mathiassen textbook. How do I get a copy?
You will have to order the book directly from the publisher. Go to <http://www.marko-publishers.com> to place your order on-line. I apologize for the problems, we ordered 50 copies of the textbook and we have approximately 70 people enrolled in the class.
2. Are there any reading assignments?
Not exactly...if you have the Mathiassen textbook go ahead and read the first two chapters. The rest of the book describes their particular object-oriented design method, so we will return to Mathiassen later in the class when we cover OO design methods.
3. What is the schedule for the rest of the Semester?
I will be updating the website this week with a more comprehensive look at the schedule for the semester. I have been working on grant proposal that was due today, so I could not devote my complete attention to the class. Now that the proposal is behind me, I'll be devoting more time to the class and this website. Thanks for your patience...

Decision on CATECS students who watch the class live: Turn your homework in according to the CATECS deadlines. I decided that it is best to keep the in-class students to one set of deadlines and the CATECS students to another set of deadline.
